Maternal and neonatal outcomes in late preterm prelabour rupture of membranes: a retrospective studyLeelodharry, Vakil Kumar 05 February 2019 (has links)
Background: The management of late preterm prelabour rupture of membranes (PPROM) is associated with an increased risk of neonatal prematurity related morbidity due to many obstetric care guidelines which favour delivery at 34 weeks or immediately upon diagnosis of ruptured membranes after 34 weeks gestation. However, expectant management of this group of patients (i.e delayed delivery) between 34+0 and 36+6 weeks of gestation is associated with an increased risk of neonatal and maternal infectious morbidities.
Aim of Study: The aim of this study was to evaluate the impact of the latency period on maternal and neonatal outcomes in late preterm prelabour rupture of membranes in a regional perinatal service in Cape Town, South Africa. The latency period was defined as the time from rupture of membranes to the time of delivery. In addition, we sought to investigate whether immediate induction of labour in the absence of overt signs of infection or fetal compromise should be prioritised in women who present with late preterm prelabour rupture of membranes.
Methods: This was a retrospective cohort study carried out over a period of two years in two secondary level hospitals of the Metro West area of Cape Town. The subjects were low risk HIV negative women with singleton pregnancies with ruptured membranes in the late preterm period. Maternal and neonatal outcomes were studied between two latency periods, namely short latency (< 48 hours) and long latency period (≥ 48 hours) after ruptured membranes.
Results and Conclusion: There were no significant differences in maternal and neonatal outcomes between the two groups of latency periods when latency was defined as the time from ruptured membranes to delivery. The study favoured a delayed induction thereby improving neonatal outcomes by decreasing the complications of prematurity. There were more adverse maternal outcomes, including an increase likelihood of augmentation of labour and more operative delivery along with its major risk, that of obstetric haemorrhage, were noted in the short latency period group. Therefore, a delayed induction policy appeared to be more appropriate. Preterm delivery places the newborn at risk of prematurity. Therefore, the risk of prematurity must be balanced with the risks of intrauterine infection and antepartum haemorrhage, the two major complications of expectant management if delayed induction is to be adopted. Proper monitoring of both the pregnant woman and fetus is essential when expectant management is carried out to avoid these adverse maternal and neonatal outcomes.

A study comparing paracervical block with procedural sedation in the surgical management of incomplete/missed miscarriagesNaiker, Manasri January 2014 (has links)
Includes bibliographical references. / Objective: To compare the analgesic efficacy of Paracervical Block (1% lidocaine) with procedural sedation (Midazolam/Fentanyl) in the surgical management of incomplete/ missed miscarriages. Study design: An efficacy trial with a naturally occurring control group who received what is standard practice. The study compared two methods of analgesia. The study group received paracervical block and the control group received procedural sedation. The study ran over two consecutive months (December 2012/January 2013). Setting: Groote Schuur Hospital, a level three hospital situated in Cape Town, South Africa. Population: All women between 18 and 55 years of age that were admitted to Groote Schuur Hospital requiring a uterine evacuation following either a spontaneous incomplete or a missed miscarriage that were not excluded by any of the exclusion criteria. Methods: Over the two month period recruited participants (those patients who fit the inclusion criteria and were agreeable to participate) were allocated to either the control group (month 1) or the intervention group (month 2), depending on which month they had the uterine evacuation. Data was collected from the uterine evacuations of the recruited participants over the two month study period. Main outcome measure: The participants perceived pain during and after uterine evacuation (10 minutes and two hours), scored by the participant on an eleven point numerical pain scale. Secondary outcomes were the surgeons’ satisfaction with the analgesia, duration of procedure and complications/ side effects of the two methods of analgesia under study. Results: A total of 111 participants were recruited over the study period, 57 in the control group and 54 in the intervention group. The average pain score during the procedure was lower in the Paracervical block group compared with the procedural sedation group, but this difference was not statistically significant at a 5% level (t=-1.8495, p=0.0671). For the Paracervical block group, the ‘’pain during” mean and the standard deviation (SD) were 5.56 and 2.50 respectively, whilst for the Procedural sedation group, the mean and SD were 6.49 and 2.81 respectively. Conclusion: Paracervical block using 1% lidocaine is an effective and safe alternative to procedural sedation in the surgical management of incomplete/missed miscarriages.

Evaluation of serial beta-human chorionic gonadotrophin levels after primary treatment of molar pregnancies : can the follow-Up for surveillance of persistence or malignant transformation be shortened?Hall, Warren J. 12 1900 (has links)
Thesis (MMed)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Objective: The aim of the study was to determine whether Beta-hCG levels at various time intervals during the follow-up period after primary treatment of molar pregnancies could be used to predict progression of the disease later, in an attempt to shorten the period of surveillance. Furthermore an assessment of the demographic details and risk factors for the development of persistent trophoblastic disease was examined. Levels of compliance to the current surveillance protocol were evaluated.
Method: A retrospective analysis of all patients diagnosed with molar pregnancies at Tygerberg Hospital, Cape Town from January 2000 to December 2010.
Results: Among the 120 patients, 13 (19.7%) of complete moles and 10 (20%) of partial moles developed persistent trophoblastic disease. There was no statistical significance of the demographic data when comparing the two types of moles. 66% of complete and 50% of partial moles were lost to follow-up within the first six months of surveillance. A potential Beta-hCG cut-off value of 148mIU/ml at week 6 offered a sensitivity of 0.89 and specificity of 0.88 that surveillance could be terminated.
Conclusions: Patient compliance is a limiting factor in the evaluation of molar pregnancy surveillance. However, based on our results, the suggestion that termination of surveillance after primary evacuation could occur at 6 weeks if the Beta-hCG level was 148 mIU/ml or lower remains undecided, and it is our opinion that higher sensitivities and specificities are required. Further research is needed to solidify this claim. The acquisition of demographic information of our population remains a priority, in order for more informed decisions to be made. / AFRIKAANSE OPSOMMING: Doel: Die doel van die studie was om te bepaal of Beta-mCG vlakke of verskillende intervalle, gedurende die opvolg periode na primêre behandeling van mola swangerskappe gebruik kan word om siekte progressie te voorspel, en sodoende die tydperk van opvolg te verminder. Verder was die demografiese besonderhede en risiko faktore vir die ontwikkeling van persisterende trofoblastiese siekte ondersoek. Die nakoming tot die huidige toesighouding protokol was geevalueer.
Metode: ‘n Retrospektiewe analise van al die pasiënte wat gediagnoseer is met ‘n mola swangerskap by Tygerberg Hospitaal, Kaapstad vanaf Januarie 2000 tot Desember 2010.
Resultate: Van die 120 pasiënte het 13 (19.7%) van die volledige molas en 10 (20%) van die gedeeltelike molas persisterende trofoblastiese siekte ontwikkel. Daar was geen statistiese belang in die demografiese data, wanneer die twee tipe molas met mekaar vergelyk is nie. 66% van die volledige en 50% van die gedeeltelike molas was verlore met opvolg binne die eerste ses maande van opvolg. ‘n Potensiële Beta-mCG afsnywaarde van 148mIU/ml op ses weke het ‘n sensitiwiteit van 0.89 en spesifisiteit van 0.88 gewys dat toesighouding getermineer kan word.
Opsomming: Pasiënt nakoming is ‘n beperkende faktor in die opvolg van mola swangerskappe. Alhoewel, gebaseer op ons resultate, ons kan voorstel dat terminasie van “surveillance/toesighouding” na primêre lediging, kan plaasvind op 6 weke indien die Beta-mCG vlak 148mIU/ml of minder is, bly dit onbeslis. Dit is ons opinie dat hoër vlakke van sensitiwiteit en spesifisiteit nodig is. Verdere navorsing is nodig om hierdie voorstelling te staaf. Die invordering van demografiese inligting van ons populasie bly ‘n prioriteit, om sodoende meer ingeligte besluite te neem.

Pre-operative urodynamic studies : is there value in predicting post-operative stress urinary incontinence in women undergoing prolapse surgeryJanse van Rensburg, Karina 12 1900 (has links)
Thesis (MMed)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: Aims of the study
Urodynamic studies (UDS) have been suggested to be performed as part of the pre-operative work-up of patients undergoing prolapse surgery. Some women with POP have occult stress urinary incontinence (OSUI) and even if subjectively continent, have a higher incidence of developing de novo stress urinary incontinence (SUI). The aim of this study was to describe the outcome of a group of patients who had pre-operative UDS and manual prolapse reduction.
Methods
This was a retrospective descriptive study including all women who had prolapse surgery during the period January 2006 to December 2011. Patients received routine pre-operative UDS and manual reduction of prolapse, performed at maximum bladder capacity determined by UDS. Patients demonstrating urodynamic SUI or OSUI were offered a concomitant anti-incontinence procedure. Post-operative follow-up data included symptoms of SUI and clinical evidence of SUI.
Results
The final group consisted of 131 women. The mean age of the patients was 57 years (range 33 to 79) and parity 3.6 (range 0 to 7). The mean body mass index was 32 (range 19 to 53). Twenty-four (18.3%) women had demonstrable SUI on clinical examination at initial presentation in the clinic. At the time of urodynamic studies, forty patients (30.5%) had evidence of SUI determined by either UDS and/ or cough test in the standing position at maximum bladder capacity. Ninety-one women (69.5%) had no evidence of UI on UDS, of which 20(15.3%) demonstrated OSUI (SUI on manual reduction of prolapse at maximal bladder capacity determined by UDS). Of the 40 women with UI on UDS, 36 had 1-step surgery (combination of anti-incontinence procedure and prolapse repair) and 4 had prolapse surgery alone. Of the 20 women with OSUI on UDS, 16 had 1-step (combined) surgery and 4 prolapse surgeries only. Of the 4 who had prolapse surgery alone, 3 complained of post-operative SUI. In the group with no SUI on UDS and manual reduction of POP, 69 of the 71 women had follow-up data. Only 1 had demonstrable SUI on examination. The manual reduction test had a sensitivity of 42.9% and a specificity of 98.5% (95% CI, 92.0-99.9%). The positive predictive value was 75.0% (95% CI, 19.4-99.3%), with a high negative predictive value of 94.4% (95% CI, 86.2-98.8%). Conclusion
The numbers in our study are too small to determine sensitivity and positive predictive value of UDS and manual prolapse reduction for the detection of OSUI. However, our data shows promise in identifying POP patients without OSUI, which is a complement of the hypothesis. We recommend that UDS can be performed pre-operatively in women undergoing prolapse surgery, to identify patients with urodynamic stress incontinence. Manual reduction of the prolapse at maximum bladder capacity can then be done to identify a subgroup of patients without OSUI. Future research is needed on the true predictive value of reduction stress testing with larger numbers. / AFRIKAANSE OPSOMMING: Doel van die studie
Urodinamiese studies (UDS) word voorgestel as deel van die pre-operatiewe ondersoeke voor prolaps chirurgie gedoen word. Sommige vroue met genitale prolaps het verborge druklek, en selfs as hulle subjektief kontinent is, het hulle ‘n groter insidensie van de novo druklek. Die doel van die studie was om die uitkoms van ‘n groep pasiënte wat pre-operatiewe UDS en manuele prolaps reduksie gehad het, te beskryf.
Metodes
Die studie was ‘n retrospektiewe beskrywende studie. Al die pasiënte wat prolapse chirurgie in die tydperk Januarie 2006 tot Desember 2011 gehad het, is ingesluit. UDS en manuele prolaps reduksie tydens maksimale blaaskapasiteit, bepaal deur UDS, was deel van die roetine pre-operatiewe ondersoeke. In die gevalle waar urodinamiese druklek of verborge druklek demonstreer is, is die opsie van ‘n meegaande prosedure vir kontinensie tydens prolaps chirurgie aangebied. Post-operatiewe opvolg inligting het simptome van druklek en kliniese bewys van druklek ingesluit.
Resultate
Die finale groep was 131 vroue reikwydte. Die gemiddelde ouderdom van die pasiënte was 57 jaar (reikwydte 33 - 79) en pariteit 3.6 (reikwydte 0 - 7). Die gemiddelde liggaamsmassa indeks was 32 (reikwydte 19 - 53). Vier-en-twintig (18.3%) vroue het aantoonbare druklek gehad met kliniese ondersoek tydens die eerste kliniek afspraak. Tydens UDS het 40(30.5%) pasiënte druklek getoon tydens UDS en/ of hoestoets in die staande posisie teen maksimale blaaskapasiteit. Een-en-negentig (69.5%) het geen tekens van urinêre inkontinensie tydens UDS demonstreer nie, waarvan 20(15.3%) verborge druklek demonstreer het (druklek met reduksie van prolapse tydens maksimale blaaskapasiteit, bepaal deur UDS). Veertig pasiënte het urodinamiese druklek gehad, waarvan 36 een-stap chirurgie (‘n kombinasie van prolaps herstel en meegaande kontinensie prosedure) en 4 prolaps chirurgie alleenlik gehad het. Uit die 20 vroue met verborge druklek tydens UDS, het 16 een-stap (kombinasie) chirurgie en 4 prolaps chirurgie alleen gehad. Uit die 4 wat prolaps chirurgie alleen gehad het, het 3 post-operatiewe klagtes van druklek gehad. In die groep wat geen inkontinensie tydens UDS en manuele prolaps reduksie gehad het nie, het 69 van die 71 vroue opvolg data gehad. Druklek kon net by een pasiënt met ondersoek demonstreer word. Die manuele reduksie toets het ‘n sensitiwiteit van 42.9% en ‘n spesifisiteit van 98.5% (95% CI, 92.0-99.9%) gehad. Die positiewe voorspellingswaarde was 75.0% (95% CI, 19.4-99.3%), en die negatiewe voorspellingswaarde was 94.4% (95% CI, 86.2-98.8%).
Gevolgtrekking
Die getalle in ons studie was te min om te bepaal wat die sensitiwiteit en positiewe voorspellingswaarde van UDS and manuele prolaps reduksie is om verborge druklek te demonstreer. Die belowende data om pasiënte te identifiseer met genitale prolaps sonder verborge druklek (‘n kompliment van die hipotese). UDS kan pre-operatief gedoen word in pasiënte wat prolapse herstel chirurgie benodig, om pasiënte met urodinamiese druklek te identifiseer. Manuele reduksie van die prolaps tydens maksimum blaas kapasiteit kan dan volg, om ‘n subgroep van pasiente sonder verborge druklek, uit te ken. Verdere navorsing, met groter getalle word benodig om die werklike voorspellende waarde van die reduksie toets te ondersoek.

How safely can we follow up post-term pregnancy with uncertain gestation using amniotic fluid index measurementMohamed, Amenah Mahmoud Mustafa 12 1900 (has links)
Thesis (MMed)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: Background:
Studies about management of prolonged pregnancy dealt with pregnancy with certain gestational age, confirmed with early ultrasound scans.
Objective: The primary aim for the study is to review the current management of uncertain gestational age (GA) post term pregnancy in Tygerberg Academic Hospital (TBH). Women at 42 weeks with an uncertain GA and an amniotic fluid index (AFI) of ≥ 10 cm as well as reassuring cardiotocographs (CTG) would be assessed to determine whether follow up over one week or two weeks are required.
Method:
A retrospective descriptive study included all patients with an uncertain gestation of 42 weeks referred to TBH.
Results:
A total of 135 pregnant women were studied. Booking fundal height (BFH) was used to determine GA in 99% and last menstrual period (LMP) in 1% of patients. The time interval between first evaluation at 42 weeks and delivery varies between 0 to 46 days (median 10 days); 104 women delivered vaginally (71% spontaneously, 6% after induction of labour (IOL)); 31 women (23%) by caesarean section; 1 elective, 4 due to cephalopelvic proportion (CPD), 5 had failed IOL, 3 poor progress and 18 fetal distress. Out of the total 11 (8%) women with AFI ≥ 10 had caesarean sections for fetal distress within 2 weeks of the visit at 42 weeks. No neonatal morbidity or mortality was noted in this study.
Conclusion:
Weekly monitoring with AFI and CTG for women at 42 weeks with unsure gestation is safe. A follow-up following 2 weeks cannot be recommended as 8% of women required caesarean sections within less than 2 weeks due to fetal distress. / AFRIKAANSE OPSOMMING: Agtergrond:
Studies oor verlengde swangerskap handel oor swangerskappe met seker swangerskapsduurte, bevestig met vroeë ultraklank skandering.
Doelwit: Die primêre doelwit van die studie is om die huidige hantering van verlengde swangerskap met onseker swangerskapsduurte by Tygerberg Hospitaal (TBH) te beoordeel. Vroue wat volgens onseker swangerskapsduurte 42 weke swanger is met ‘n amnionvogindeks (AVI) van >10 en gerusstellende kardiotokogramme (KTG) sal nagegaan word om te bepaal of opvolg oor een of twee weke nodig is.
Metode:
‘n Retrospektiewe studie wat alle pasiënte insluit wat na Tygerberg Akademiese Hospitaal verwys word wat ‘n onseker swangerskapsduurte van 42 weke het.
Resultate:
‘n Totaal van 135 vroue is bestudeer. Die fundale hoogte is gebruik om swangerskapsduurte te bepaal in 99% van gevalle en die laaste menstruasie in 1%. Die tydsinterval tussen die eerste evaluasie op 42 weke en verlossing wissel tussen 0 en 46 dae (mediaan 10 dae); 104 vroue het ‘n vaginale verlossing gehad (71% met spontane aanvang van kraam, 6% na induksie van kraam); 31 (23%) is met keisersnitte verlos; 1 elektief, 4 as gevolg van skedelbekken disproporsie, 5 gefaalde induksies, 3 swak vordering en 18 met fetal nood. Uit die totaal was daar 11 (8%) vroue met ‘n AVI ≥ 10 wat keisersnitte vir fetale nood binne 2 weke van die besoek op 42 weke gehad het. Geen neonatale morbititeit of mortaliteit het in die studie voorgekom nie.
Gevolgtrekking:
Weeklikse monitering met AVI en KTG vir vroue wat 42 weke swanger is met onseker swangerskapsduurte, is veilig. Opvolg na 2 weke kan nie aanbeveel word nie want 8% het keisersnitte vir fetale nood gehad na minder as 2 weke.

A study of different clinical and biochemical parameters in polycystic ovary syndrome affecting ovulation induction outcome and fertility potentialSiebert, T. I. 12 1900 (has links)
Thesis (DMed (Obstetrics and Gynaecology))--Stellenbosch University, 2008. / Chapter 1 presents a literature study on the diagnostic debate of PCOS. The literature study
includes a discussion of the recent Rotterdam consensus statement regarding the diagnosis of
PCOS. This is followed by a discussion on the essential work-up of the patient presenting with
PCOS. Finally, chapter 1 presents a discussion on the complexity of the different variations in
women presenting with PCOS.
Chapter 2 is a literature review on ovulation induction methods in patients who present with
PCOS. This literature study puts special emphasis on the different available methods used for
ovulation induction in women with PCOS and the profounding effect weight loss will have in
managing these patients. This chapter also addresses the use of newer agents, like aromatase
inhibitors (Letrozole), and the current role of each of these agents in ovulation induction protocols.
Chapter 3 is a literature overview on the effect of Metformin in Clomiphene-resistant PCOS
women. The inclusion criteria of this review was all prospective randomized trials where Metformin
was added for ovulation in the Clomiphene-resistant PCOS patient. The data is presented as a metaanalysis.
Chapter 4 is a prospective randomise control trial to evaluate the benefit of metformin if added to
Clomiphene in a primary ovulation induction protocol in comparison to Clomiphene alone. This
chapter also evaluates all factors influencing ovulation outcome. Finally in the discussion section all
the recent studies published addressing this topic were reviewed.
Chapter 5 is a literature review to evaluate the classification systems for semen parameters and the
in vivo fertility potential. This data is also used to establish fertility/subfertility thresholds for semen
parameters.
This chapter also presents the results of a prospective and retrospective study of the semen analysis
of the partners of women with PCOS. We believe that this population presents the best reference
group to study the semen profile of the general male population.
Chapter 6 is a summary of the results of these studies and serves as an evidence based approach for
ovulation induction in women with PCOS.

Use and Misuse of Oxytocin During DeliveryJonsson, Maria January 2009 (has links)
Obstetric malpractice claims, concerning delivery during a period of eight years, were analysed for motives behind disciplinary actions, and for the frequency of inappropriate oxytocin use.Failure to respond to signs of foetal distress, injudicious use of oxytocin and a failure to effect a timely delivery were the recurrent problems that accounted for the majority of disciplinary actions. Inappropriate use of oxytocin was more frequent than reported in earlier studies. (Paper I) In a case-control study, differences in the obstetric management in neonates born with and without acidaemia (umbilical artery pH < 7.05), was evaluated. Out of 28,486 deliveries during 1994–2004, 305 neonates were born with acidaemia. Uterine hyperactivity and oxytocin use were independently associated to acidaemia at birth. The increased uterine activity was related to oxytocin treatment in 75 % of cases. Pathological cardiotocographic patterns occurred significantly more often in the case group. The results indicate that guidelines on oxytocin use and foetal surveillance are not followed. The duration of bearing down is less important when uterine contraction frequency has been considered. (Paper II) In a subset of study II, cases with metabolic acidosis (umbilical artery pH < 7.05 and base deficit ≥12 mmol/L) and controls were audited for the occurrence of suboptimal intrapartum care, and the nature of such care. It was found that suboptimal care occurred in half (49%) of the cases, while it was less frequent but not uncommon among controls (13%). Suboptimal care consisted of injudicious use of oxytocin and a failure of appropriate action upon signs of foetal distress. A high rate of NICU admissions and diagnosis of encephalopathy in the case group confirms that metabolic acidosis should be avoided. We estimate that metabolic acidosis could probably have been prevented in 40-50% of the cases.(PaperIII) Women (n=103) scheduled for elective caesarean section in regional anaesthesia were randomised to 5 or 10 units oxytocin, given as an intravenous bolus (double blinded), and electrocardiograms were analysed for ST depressions as a sign of myocardial ischaemia. ST depressions were associated with oxytocin administration significantly more often in subjects receiving 10 compared with 5 units. A dose of 10 units resulted in a more marked decrease of the mean arterial blood pressure, but no difference in increase of the heartrate. There was no difference in estimated blood loss. (paper IV)

Maternal position during caesarean section for preventing maternal and neonatal complications : a cochrane reviewCluver, Catherine Anne 12 1900 (has links)
Thesis (MMed)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Background: During caesarean section mothers can be in different positions. Theatre tables could be tilted laterally, upwards, downwards or flexed and wedges or cushions could be used. There is no consensus on the best positioning at present. Objectives: We assessed all available data on positioning of the mother to determine if there is an ideal position during caesarean section that would improve outcomes. Search methods: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (September 2009), PubMed (1966 to 14 September 2009) and manually searched the references of retrieved articles. Selection criteria: Randomised trials of women undergoing caesarean section comparing different positions. Data collection and analysis: Two authors assessed eligibility, trial quality and extracted data. Results: We identified 17 studies with a total of 683 woman included. We included nine studies and excluded eight studies. Included trials were of variably quality with small sample sizes. Most comparisons had data from single trials. This is a shortcoming and applicability of results is limited. The incidence of air embolism was not affected by head up versus horizontal position (risk ratio (RR) 0.91; 95% confidence interval (CI) 0.65 to 1.26). We found no change in hypotensive episodes when comparing left lateral tilt (RR 0.11; 95% CI 0.01 to 1.94), right lateral tilt (RR 1.25; 95% CI 0.39 to 3.99) and head down tilt (mean difference (MD) -3.00; 95% CI -8.38 to 2.38) with horizontal positions or full lateral tilt with 15-degree tilt (RR 1.20; 95% CI 0.80 to 1.79). Hypotensive episodes were decreased with manual displacers (RR 0.11; 95% CI 0.03 to 0.45), a right lumbar wedge compared to a right pelvic wedge (RR 1.64; 95% CI 1.07 to 2.53) and increased in right lateral tilt (RR 3.30; 95% CI 1.20 to 9.08) versus left lateral tilt. Position did not affect systolic blood pressure when comparing left lateral tilt (MD 2.70; 95% CI -1.47 to 6.87) or head down tilt (RR 1.07; 95% CI 0.81 to 1.42) to horizontal positions, or full lateral tilt with 15-degree tilt (MD -5.00; 95% CI -11.45 to 1.45). Manual displacers showed decreased fall in mean systolic blood pressure compared to left lateral tilt (MD -8.80; 95% CI -13.08 to -4.52). Position did not affect diastolic blood pressures when comparing left lateral tilt versus horizontal positions. (MD-1.90; 95% CI -5.28 to 1.48). The mean diastolic pressure was lower in head down tilt (MD -7.00; 95% CI -12.05 to -1.95) when compared to horizontal positions. There were no statistically significant changes in maternal pulse rate, five-minute Apgars, maternal blood pH or cord blood pH when comparing different positions. Authors' conclusions There is limited evidence to support or clearly disprove the value of the use of tilting or flexing the table, the use of wedges and cushions or the use of mechanical displacers. Larger studies are needed. / AFRIKAANSE OPSOMMING: Agtergrond:
Tydens keisersnitte kan moeders in verskillende posisies wees. Teater tafels kan lateraal, opwaarts, afwaarts of gebuig word, of 'n wig en kussings kan gebruik word. Op die oomblik is daar geen konsensus oor die beste posisie nie.
Doelwitte:
Ons het alle beskikbare data oor die plasing van die moeder ondersoek, met die doel om 'n ideale posisie vir 'n verbeterde uitkoms tydens 'n keisersnit vas te stel.
Metodes: Ons het die “Cochrane Pregnancy and Childbirth Group's Trials Register“ (September 2009), PubMed (1966 tot 14 September 2009) deursoek en die herwinde artikels se verwysings per hand nagegaan.
Keuringskriteria:
Gerandomiseerde proewe van vroue wat keisersnitte ondergaan het, is in verskillende posisies vergelyk.
Data insameling en analise:
Twee outeurs het die kwaliteit, die geskiktheid en data van die studie beoordeel.
Resultate:
Ons het 17 studies geidentifiseer wat 'n totaal van 683 vroue ingesluit het. Ons het nege studies ingesluit en agt uitgesluit. Die ingeslote studies was van wisselvallige gehalte en die monster groepe was klein. Die meeste vergelykings het data van enkele studies gegee. Dit is 'n tekortkoming en die bruikbaarheid van die resultate is beperk.
Die plasing van kop-op teenoor horisontale posisie het die voorkomssyfer van lug embolisme nie geaffekteer nie.(risiko verhouding RR 0.91;95% 95% vertroue interval Cl 0.65 tot 1.26). Daar is geen hipotensiewe veranderinge gevind toe 'n vergelyking gemaak is tussen linker laterale kantel (RR 0.11; 95% Cl 0.01 tot 1.94) regter laterale kantel (RR 1.25; 95% Cl 0.39 tot 3.99) en kop-af kantel (“mean difference” MD -3.00; 95%Cl -8.38 tot 2.38) teenoor horisontale posisies of volle laterale kantel met 'n 15 grade kantel nie (RR 1.20;95% Cl 0.8. tot 1.79). Hipotensiewe episodes het verminder met hand verplasers (RR 0.11; 95% Cl 0.03 tot 0.45), 'n regter lumbale wig in vergelyking met 'n regter bekken wig (RR 1.64; 95% Cl 1.07 tot 2.53) en 'n vermeerdering van die regter laterale kantel (RR3.30; 95% Cl 1.20 tot 9.08) teenoor die linker laterale kantel.
In die vergelyking tussen die posisie van linker laterale kantel (MD 2.70; 95% Cl -1.47 tot 6.87) of kop-af kantel (RR 1.07; 95% Cl 0.81 tot 1.42) teenoor horisontale posisies, of volle laterale kantel met 15 grade kantel (MD -5.00; 95% Cl -11.45 tot 1.45) het die posisie nie die sistoliese bloeddruk geaffekteer nie. Hand verplasers het 'n verminderde daling in gemiddelde sistoliese bloeddruk veroorsaak in vergelyking met linker laterale kantel plasing (MD -8.80;95% Cl-13.08 tot -4.52).
In die vergelyking tussen linker laterale kantel en horisontale posisie was daar geen effek op die diastoliese bloeddruk nie (MD -1.90; 95% Cl -5.28 tot1.48). Die gemiddelde diastoliese druk was laer in die kop-af kantel (MD -7.00; 95% Cl -12.05 tot -1.95) in vergelyking met horisontale posisies.
In die vergelyking tussen die verskillende posisies was daar geen betekenisvolle statistiese veranderinge in die moeder se polstempo, vyf minute Apgartellings, moederlike bloed pH of naelstringbloed pH nie.
Outeur se gevolgtrekkings:
Daar is beperkte getuienis om die waarde van kantel, buiging van tafel, die gebruik van wieë en kussings of die gebruik van maganiese verplasers te ondersteun of totaal te verwerp. Groter studies is nodig.

Breech deliveries in Tygerberg Academic Hospital : maternal and neonatal outcomes of vaginal and abdominal deliveries - a case-controlled studyLindeque, L. X. 12 1900 (has links)
Thesis (MMed)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: The Objective: To review the difference in short term neonatal and maternal outcomes
among singleton infants with breech presentation delivered by vaginal or elective caesarean
section route at term, at Tygerberg Academic Hospital (TBH) in Cape Town.
The study design was a retrospective case control study.
Method:
Part I
A total of 120 patients were selected. 60 vaginal breech deliveries and 60 elective caesarean
sections for breech presentation (comprising the control group). 60 cases of vaginal
deliveries were collected and 60 control cases of planned elective caesarean sections, where
the indication for CS was breech presentation, were collected in the same manner.
Part II
Nineteen registrars completed a questionnaire regarding their subjective experiences of
vaginal breech deliveries at Tygerberg Academic Hospital.
Results:
Part I
An analysis of the results found statistically significant differences in maternal ages between
the two groups, with younger women delivering by CS; gravidity and parity was lower in the
CS group; blood loss was observed to be higher in the CS group with more women requiring
a blood transfusion when compared to vaginal delivery; there were more neonatal
admissions in the vaginal delivery group as well as more birth trauma, neonatal seizures and
death in this group; Apgar scores were higher in the CS group and finally, neonates born by
CS were more commonly discharged at the same time as their mothers in the CS group.
Part II
When analyzing the registrar questionnaire it can be noted that although clinicians are
performing an adequate number of breech vaginal deliveries, with an average of 10
deliveries per year, the skills training for clinicians is invaluable. Not all registrars learned
skills from a senior clinician and skills training in skills labs are essential for initial and even
continual training of these clinicians. It is suggested that these skills training programs be made compulsory for all registrars and that a biyearly attendance and completing of such a
course be mandatory for those wishing to work in the labour ward.
Conclusions:
Although not statistically significant, there was more morbidity and mortality associated
with vaginal breech delivery. / AFRIKAANSE OPSOMMING: Doel: Om die korttermyn neonatale en moederlike uitkomste van enkeling swangerskappe
met stuitligging wat vaginaal of met elektiewe keisersnee verlos is by die Tygerberg
Akademiese Hospitaal in Kaapstad, te bepaal.
Die werkstuk is ‘n retrospektiewe gekontroleerde-gevallestudie.
Metode:
Deel 1
‘n Totaal van 120 pasiënte is gekies. 60 gevalle van vaginale stuitverlossings en 60 kontrolegevalle
van beplande elektiewe keisersnitte waar die indikasie stuitligging was.
Deel 2
Negentien kliniese assistente het die vraelys oor hul persoonlike ervaring van vaginale
stuitverlossing by die Tygerberg Akademiese Hospitaal ingevul.
Resultate:
Deel 1
‘n Ontleding van die resultate wys statisties betekenisvolle verskille in die moederouderdom
van die twee groepe, met meer jong vroue wat met keisernit geboorte gee.
Graviditiet en pariteit was laer in die keisersnit-groep. Bloedverlies was hoër in die
keisersnit-groep en in vergelyking met die vaginale verlossings met meer vroue wat
bloedoortapping benodig. In die vaginale verlossingsgroep was meer neonatale toelatings
nodig asook meer geboortetrauma, neonatale konvulsies en sterftes. Apgar-tellings was
hoër in die keisersnitgroep en neonate wat met ‘n keisersnitte gebore is, is meer dikwels
saam met hul moeders ontslaan.
Deel II
Ontleding van die vraelys vir kliniese assistente wys dat hoewel klinici ‘n genoegsame getal
van gemiddeld 10 vaginale stuitverlossings per jaar uitvoer, vaardigheidsopleiding vir klinici
van onskatbare waarde sal wees.
Nie alle kliniese assistente leer vaardighede by senior klinici nie en opleiding in ‘n
vaardigheidslaboratorium is noodsaaklik vir die aanvanklike en selfs voortdurende opleiding
van dié kliniese assistente. Dit word voorgestel dat hierdie vaardigheidkursusse verpligtend gemaak word vir alle kliniese asssistente en bywoning en voltooiing van die kursus twee
maal per jaar verpligtend moet wees vir diegene wat in ‘n kraamsaal wil werk.
Gevolgtrekking:
Vaginale stuitverlossings, hoewel nie stastisties betekenisvol nie, het met meer morbiditeit
en sterftes gepaardgegaan.
