Nursing care for pediatric patients with central venous access devicesReid, Jacqueline, G 08 January 2015 (has links)
Abstract
Central venous access devices (CVADs) have become essential interventions for pediatric patients. However, their use is associated with serious complications. The most common and potentially preventable complication is catheter related blood steam infections (CRBSIs). Despite the implementation of interventions that have been shown to decrease their risk, CRBSIs still occur. Pediatric nurses were surveyed regarding their knowledge and application of recommended CVAD care practices, and their perspectives on possible factors that could contribute to the incidence of CRBSIs. Donabedian’s (1966) Structure-Process-Outcome Model guided the study. A cross-sectional, descriptive and exploratory mixed-methods survey design was used. The convenience sample consisted of 93 pediatric nurses. Findings indicate areas of concern related to adherence to CVAD care guidelines and situations that could interfere with the provision of recommended CVAD care. The primary factor identified was the use of improper technique by members of the healthcare team and the patients’ families.

Vliv využití Midline a PICC katétrů na četnost komplikací spojených s žilními vstupy u hospitalizovaných pacientů / Influence of Midline and PICC catheters use on frequency of complications associated with venous lines in hospitalised patientsHromádková, Jaroslava January 2019 (has links)
Presented dissertation deals with the problematics of optimal choice of venous access for each hospitalized patient at standard internal wards. Introduction of vascular access must be safe for the patient and must allow the fulfillment of all the goals for which it was indicated. In recent years, in addition to peripheral cannulas and non-tunneled central catheters, introduction of midline catheters and PICC gets into everyday practice. The choice of optimal vascular access device since adminition can bring benefit to the patients in the form of decline of complications. Goal: The goal of master thesis was to prove that the use of new types of vascular access devices has influence on the decline of vascular access devices related complication occurence. Methods: To reach the goal we used a quantitative method of data collection during certain time period using created collection protocols. Research investigation took place from November 2017 to February 2018 at two standard wards of Department of Internal Medicine FN Motol. Results: A total of 350 venous access devices (271 peripheral cannulas, 54 midline catheters, 35 PICC) in 187 hospitalized patients was monitored. Prevalence of complications, average length of placement and reasons for extraction of individual vascular access devices was...

Komplikationer hos patienter med PICCKarevaara, Anette January 2013 (has links)
SAMMANFATTNING Bakgrund: PICC är en central infart som används inom vården för att kunna ge kärlretande läkemedel. Komplikationer vid användning av PICC kan vara infektion, trombos, tromboflebit eller stopp i katetern. Syfte: Syftet med studien är att undersöka förekomsten av komplikationer av PICC hos onkologiska patienter samt för att se om det finns några skillnader mellan olika diagnosgrupper och behandlingar med avseende på förekomsten av djupa ventromboser (DVT) och infektioner. Syftet är också att ta reda på hur länge en PICC sitter och hur vanligt det är att en PICC felplaceras. Metod: Metoden som används är en retrospektiv, deskriptiv, kvantitativ undersökning. I studien ingår alla onkologpatienter som fått en PICC år 2009-2011 (n=677). Data samlades in med hjälp av journalgranskning. Resultat: Förekomsten av DVT var 5,6 %. Patienter som fick behandling med Capecitabin hade statistiskt signifikant mer DVT jämfört med andra behandlingar. Patienter som fick behandling med R-CHOP hade statistiskt signifikant mindre DVT jämfört med andra behandlingar. Antalet infektioner var 3 %. Stopp i katetern drabbade 1,8 % av patienterna, 17 % hade besvär med rodnad under förbandet, 12 % av alla katetrar åkte ut 4 cm eller mer och 2,5 % av katetrarna felplacerades vid inläggningen. En PICC var insatt i medelvärde 92 dagar, median 105 dagar. Slutsats: Förekomsten av komplikationer av PICC var låg hos onkologiska patienter med undantag för hudbesvär som förekom hos var sjätte patient. Behandlingar innehållande Capecitabin förefaller öka risken för DVT men fler studier behövs för att öka kunskaperna om detta. PICC är en säker venös infart vid behandling med cytostatika. / ABSTRACT Background: PICC (peripherally inserted central catheter) is a central line used in healthcare to provide vascular irritant drugs. Complications with PICC can be infection, thrombosis, thrombophlebitis or occlusion of the catheter. Aim: The aim of the study is to examine the incidence of complications of PICC in oncology patients and to see if there are any differences between diagnostic groups and treatments for the presence of deep venous thrombosis (DVT) and infection. The aim is also to find out for how long time a PICC is inserted and how common it is for a PICC misplaced. Method: The method used is a retrospective, descriptive, quantitative survey. The study includes all oncology patients who received a PICC years 2009-2011 (n=677). Data were collected through medical record review. Results: The incidence of DVT was 5,6 %. Patients treated with Capecitabin had statistically significantly more DVT compared with other treatments. Patients treated with R-CHOP had statistically significantly less DVT compared with other treatments. The incidence of infections was 3 %. Occlusion of the catheter affected 1,8 % of patients, 17 % had problems with redness under the dressing, 12 % of all catheters went out four cm or more and 2,5 % of the catheters were misplaced at insertion. A PICC was inserted in mean 92 days, median 105 days. Conclusion: The complication rate of PICC was low in oncology patients with the exception of skin problems that occurred in every sixth patient. Treatments containing Capecitabin appears to increase the risk of DVT but more studies are needed to raise awareness of this. PICC is a safe venous access for chemotherapy.

Midline ur ett banperspektiv : en intervjustudie med sjuksköterskorJuhlin, Emma, Ellefors, Fredrika January 2022 (has links)
Bakgrund: Barn som vårdas på sjukhus är ofta i behov av någon form av venaccess. På flera platser i Sverige finns enbart perifiera venkatetrar att tillgå när en central infart ej är aktuellt. För barn med långvarigt behov av intravenösa läkemedel kan detta orsaka upprepade stick och kateterbyten. Midline är en perifer venaccsess med längre hållbarhet som nyligen börjat användas inom pediatrisk vård. Syfte: Studiens syfte är att undersöka sjuksköterskors erfarenheter av att vårda barn med Midline. Metod: Studien genomfördes med kvalitativ metod genom semistrukturerade intervjuer.Därefter utfördes en innehållsanalys för att besvara studiens syfte. Deltagarna var nio sjuksköterskor vid fyra olika sjukhus i mellersta och södra Sverige. Resultat: Analysen resulterade i kategorierna: En ny typ av infart, En vårdupplevelse med barnet i fokus samt Att företräda barnen. Tillgång till en infart som var säker och hade längre hållbarhet än andra perifiera venkatetrar uppskattades av deltagarna. Tydliga instruktioner och rutiner ansågs viktiga. En stor fördel med Midline ur ett barnperspektiv var färre stick i samband med långvarigt behov av venaccsess. Samt vikten av det interprofessionella samarbetet som krävs för att få inläggning av katetern att bli så bra som möjligt. Slutsats: Deltagarna såg Midline som ett bra alternativ till andra perifiera infarter i vården av barn med behov av långvarig venaccess. Detta då det minskade lidandet för barnen samt att det gav en möjlighet till lek och vistelse utanför sjukhus som annars hade varit svårt att tillgodose. / Background: Children in hospital care may need venous access. In many places in Sweden the only type of access available is peripheral venous catheter or central lines. For children with a long need of intravenous treatment this can cause repeated procedures and pain.Midline is a peripheral venousacsess with longer durability that recently has been introduced in pediatric care. Aim: To explore nurses experience of using Midline in paediatric care. Method: The method used was a qualitative design with a content analysis. Semistructured interviews were conducted with nine nurses from four different hospitals in the middle and southern parts of Sweden. Results: The participants’ experiences were categorized in three main categories: A new type of venous access, A care experience with the child in focus and To represent the child. To have a secure access with a longer durability compared to a regular venous catheter was highly appreciated by the participants. Instructions and routines where essential for the catheter to work properly. Fewer painful procedures was seen as an advantage with the Midline catheter through the children's perspective. Conclusion: The participants saw the Midline catheter as a good alternative to the regular peripheral venous catheter in the paediatric care. It was seen to decrease childrens suffering and gave a better opportunity to play and spend time outside of the hospital.

Procedimento de inserção, manutenção e remoção do cateter central de inserção periférica em neonatos / Insertion, maintenance and removal procedures of peripherally inserted central catheters in neonatesCamargo, Patricia Ponce de 30 May 2007 (has links)
O cateter central de inserção periférica (PICC) é um dispositivo cada vez mais utilizado nas Unidades de Terapia Intensiva Neonatal (UTIN). O objetivo do estudo foi caracterizar os neonatos (RN) submetidos ao procedimento de inserção do cateter PICC e descrever suas práticas de inserção, manutenção e remoção em RN. Estudo observacional com delineamento longitudinal realizado no Berçário Anexo à Maternidade do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Os dados foram obtidos pela observação dos procedimentos e informações registradas nos prontuários dos neonatos submetidos ao procedimento. No estudo, incluíram-se todos os procedimentos de inserção, manutenção e remoção de cateter PICC ocorridos entre de março e setembro de 2006, em recém-nascidos internados na unidade neonatal citada. Antes do início da coleta dos dados, o projeto de pesquisa foi apreciado e aprovado pelo Comitê de Ética em Pesquisa da Instituição, campo do estudo. No período estudado, ocorreram 37 procedimentos de inserção do cateter PICC. A média da idade gestacional e o peso dos RN eram de 32,2 semanas e 1.289,2 gramas, respectivamente. A maioria, 22 (59,4%) RN, era do sexo masculino, 18 (48,7%) RN tinham menos de três dias de vida no dia do procedimento e 35 (94,6%) RN foram submetidos à inserção do cateter para infundir nutrição parenteral total. A maioria, 21 (56,8%) RN, apresentou diagnóstico de síndrome do desconforto respiratório. A administração de fármaco sedativo previamente ao procedimento ocorreu em 4 (10,8%), nenhum RN recebeu analgesia. O tipo de cateter mais utilizado foi o de poliuretano, 35 (94,6%). A média da freqüência de punções venosas foi 3,4 e em 8 (21,6%) RN foram obtidos sucesso na introdução do cateter na primeira punção venosa. As veias mais puncionadas foram as localizadas em membros superiores, a basílica foi puncionada em 29,9% dos RN e a cefálica, em 22,8% dos RN. Fragilidade vascular, transfixação venosa e obstrução do cateter foram os principais motivos de insucesso na inserção do PICC. Alteração da viscosidade sangüínea foi uma intercorrência identificada pelas enfermeiras na inserção do PICC. A prevalência de sucesso do procedimento foi de 64,9% (24 RN). Obteve-se posicionamento central da ponta do cateter em 20 (83,3%) RN e periférico em 4 (16,7%) RN. A média da extensão do cateter introduzido em MSD foi de 11,4 cm, em MSE, 13,5cm e em região cervical, 7,1 cm. Solução de clorexidina a 0,5% foi o anti-séptico mais utilizado nos curativos e a NPT foi a solução mais infundida pelo cateter. O tempo médio de permanência do cateter foi 8,9 dias, 11 (27,5%) foram removidos em decorrência de infecção do cateter, 7 (17,5%) pelo término da terapia intravenosa e 7 (17,5%) por obstrução. Dos 24 cateteres removidos, 14 (58,3%) foram enviados para cultura, dos quais, 10 (71,4%) tiveram resultado negativo. Das quatro pontas com resultado positivo, em duas (14,3%) foram identificados Estafilococos coagulase negativa / The peripherally inserted central catheter (PICC) are increasingly employed in the neonatal intensive care units. The aims of the study were to characterize the neonates who underwent PICC catheter insertion and to describe insert, upkeep and removal PICC catheter practices in neonates. Prospective cohort study carried out at Neonatal Intensive Care Unit of University of São Paulo School Medical Hospital. Data were obtained by nurse procedures performance observation and from the medical chart records of the neonates who underwent PICC catheter insertion. Data were collected from March to September, 2006 and all the neonates underwent PICC catheter insertion during this period were included in the study. The study protocol was approved by the Research Ethics Board of the Hospital where the study was carried out. Written informed consents were obtained from parents or legal guardian of all infant newborns underwent PICC catheter insertion and from certified registered nurses responsible for catheter insertion, maintenance of the line and for removal it. It was obtained data from 32 infants newborn underwent procedure of PICC catheter insertion. The gestacional age and infant weight mean were, 32.2 weeks and 1289.2 g, respectively; 22 (59.4%) neonates were male, the PICC catheter was inserted in 18 (48.7%) neonates in the first three days of life and 35 (94.6%) babies were underwent PICC insertion to provide total parenteral nutrition; 21 (56.8%) neonates had diagnosis of respiratory distress syndrome, any of them received analgesics and 4 (10,8%) newborns received sedation. The polyurethane catheter was more used, 35 (94,6%) than the silicone catheter, 2 (5,4%). The mean of venous puncture frequency was of 3.4 and the rate success obtained in the first attempt was 21,6% (8 newborn). The most accessed veins for insertion PICC lines were basilic, 29,9% and cephalic, 22,8%. Vascular fragility, venous transfixation and obstruction were the majorities causes of failure to insert the PICC line. The frequency of success on PICC line insertion was 64,9% (24 neonates). The position of tip catheter in 83,3% (20 neonates) was central (superior vena cava), others 16,7% (4 neonates) tips was peripherally. The length of catheter line mean to thread in right arm veins was 11,4 cm, in the left arm,13,5cm and in the jugular vein was 7,1 cm. It was used chlorhexidine 0.5% antiseptic solution in the majority of catheter insertion site dressing. Total parenteral nutrion was the soluction infused by the catheter line. The mean time of remaining the catheter was 8.9 days, 11(27,5%) catheters were withdrawn due to suspect of catheter infection, 7(17,5%) catheters withdrawn after end the intravenous therapy and 7 (17,5%) due to obstruction. From 24 catheters withdrawn, 14 (58,3%) tip catheters were underwent to microbyological analysis and the results were negative for 10 (71,4%) analysis, from others four tips catheter which results were positive, in two (14,3%) identified coagulase-negative staphylococci

Trvalý cévní přístup u dialyzovaných pacientů z pohledu sestry. / Permanent Vascular Access in Dialysis Patients from the viewpoint of Nurses and Patients.ŠVÁBOVÁ, Veronika January 2010 (has links)
The issue of chronic renal failure and cannulation of permanent venous accesses in patients treated at haemodialysis centres is a topical and widespread problem of these days. According to generally accessible resources the incidence of terminal stage of renal failure, and thus the necessity to treat a patient by means of elimination methods, is very high, it reaches four individuals per thousand inhabitants according to the statistics. It is obviously a widespread nursing problem. The theoretical part of the thesis is divided into a summary and description of the present situation in chronic renal failure, particularly a brief insight into the chronic renal failure and its causes and syndromes. It also deals with the topic of the present treatment possibilities with stress on patient treatment at nephrologic outpatient clinics and in haemodialysis centres. The next chapter of the thesis describes the development from haemodialysis history up to the present advanced elimination methods. The present elimination methods bring the necessity of functional provision of venous access, particularly cannulation of AV fistulas, it is a very frequent nursing operation provided by nurses treating chronically affected patients at haemodialysis centres. This chapter is concluded by general knowledge of the techniques of cannulation of permanent venous accesses, possible occurrence of complications during the cannula penetration itself in relation to the physical phase of nursing treatment about patients with chronic renal failure. The practical part of the thesis was aimed at discovering or possible confirmation of the hypotheses discussed in the theoretical part. The practical research was based on searching for problems among dialyzed patients related to the permanent venous access, on finding the approach of nurses working at dialysis centres to cannulation of permanent accesses and on mapping the access of patients with permanent venous access to nurses with short time experience at a dialysis centre. Research questions were determined for this purpose and were processed within qualitative research into case reports upon depth interviews with nurses working at the dialysis centres of České Budějovice Hospital, Český Krumlov Hospital and Písek Hospital and their patients. The research data were processed into charts, where responses from patients and those from nurses were assessed separately. Occurrence frequency of the individual answers was particularly monitored in the individual output tables, however the responses were not processed by means of standard statistic methods because of the chosen methodology and thus a low number of respondents, but the output data served for drawing conclusions and preparing recommendations for application of nursing methods. The thesis conclusion summarizes the obtained knowledge and recommends possible procedures of solving the problems of cannulation of permanent venous accesses in patients with chronic renal failure treated at haemodialysis centres.

Centrala venösa infarter på röntgenavdelningen : En litteraturöversikt om patientsäkerhet och bildkvalitet / Central venous access in the radiology department : A literature review on patient safety and image qualityLankinen, Minna, Westman, Marina January 2020 (has links)
Centrala venösa infarter används inom vården för att administrera läkemedel, ge parenteral nutrition och för blodprovstagning. Indikationer på att en patient behöver en central venös infart är att patienten behöver akut vård eller långvarig intravenös administrering av läkemedel. Många av dessa patienter behöver dessutom genomgå undersökningar via datortomografen (DT), där kontrastmedel kan krävas för att undersökningen ska kunna utföras. Syfte: Syftet med litteraturöversiktet var att sammanställa kunskap om centrala venösa infarters användbarhet vid administrering av kontrastmedel i samband med DT undersökningar. Metod: En allmän litteraturöversikt som baseras på tolv kvantitativa artiklar. Resultat: I de tolv artiklarna så uppmärksammades fyra kategorier som syftar till användbarheten: Tryck och Flödeshastigheter, Kateterspetsläge, Efterspolning och Diagnostisk bildkvalitet. Flera av studierna visade på kateterspetsförskjutning i samband med en kontrastmedelsinjektion med tryckspruta på DT. Tre av de fyra studier som kontrollerade bildkvalitet visade på bra diagnostisk bildkvalitet. Slutsats: Centrala venösa infarter är användbara vid administrering av kontrastmedel under datortomografiundersökningar under förutsättning att röntgensjuksköterskan har rätt kunskap om användandet av dem. Nationella riktlinjer behövs för att underlätta röntgensjuksköterskans arbete med dem så att hanteringen av dem utförs patientsäkert. / Central venous access is used in healthcare for drug administration, blood sampling, and providing parenteral nutrition. Indications for a patient needing a central venous access are either that a patient needs urgent care or prolonged intravenous administration of drugs. Many of these patients also need to undergo examinations via computed tomography (CT), where contrast agents may be required for the examination to be performed. Purpose: The purpose of the literature review was to compile knowledge about the usability of central venous access during the administration of contrast agents in connection with CT examinations. Method: A general literature review based on twelve quantitative articles was performed. Result: In the twelve articles, four categories were observed with the aim being usefulness: Pressure and Flow Rates, Catheter Tip position, Flushing and also Diagnostic Image Quality. Several of the studies showed catheter tip displacement being in connection with a contrast injection of a syringe during the CT examinations. Three of the four studies that controlled image quality showed good diagnostic image quality. Conclusions: Central venous access is useful in the administration of contrast agents during computed tomography examinations, provided that the radiographer has the correct knowledge of their use. National guidelines are needed to facilitate the radiographers work with them so that their usability is carried out with patient safety in mind.
