Doenças cardíacas congênitas são as mais frequentes entre as malformações congênitas graves, afetando de duas a três crianças por 100 nascidos vivos, sendo o defeito do septo atrioventricular (DSAV) responsável por 5% desses, e atingindo cerca de 50% dos pacientes portadores de Síndrome de Down. Caracteriza-se essencialmente por vários graus de desenvolvimento incompleto do tecido septal ao redor das valvas atrioventriculares, bem como de anormalidades na formação das mesmas. Recomenda-se a correção cirúrgica ao redor de 4 meses de vida, no intuito de prevenir o surgimento de hipertensão pulmonar (HP) irreversível devida ao hiperfluxo pulmonar, no entanto a despeito disso, identifica-se a presença de hipertensão pulmonar em pacientes já submetido ä correção do defeito cardíaco. O presente estudo teve por objetivo analisar a prevalência de hipertensão pulmonar diagnosticada através do ecocardiografia e identificar dos fatores de risco em pacientes submetidos à correção cirúrgica de DSAV nos últimos 16 anos no Hospital das Clínicas da Faculdade de Medicina de Ribeirão preto da Universidade de São Paulo (HCFMRP - USP). Foram selecionados pacientes portadores de DSAV, submetidos à correção cirúrgica no HCFMRP - USP, no período de janeiro de 1999 a janeiro de 2016, em seguimento no Ambulatório de Cardiologia Infantil do HCFMRP-USP, considerados portadores de hipertensão pulmonar os pacientes que apresentaram à ecocardiografia valores estimados de pressão sistólica de artéria pulmonar (PSAP) superiores a 30 mmHg. Foram analisadas variáveis clínicas pré e pós-operatórias. Não foi encontrada correlação entre peso e idade na data da correção cirúrgica e presença de HP na avaliação ecocardiográfica pós-operatória; no entanto esta se relacionou com tempo prolongado de circulação extra-corpórea e ventilação mecânica. Houve aumento significativo na sobrevida nos últimos oito anos analisados, refletindo a melhoria na qualidade de atendimento clinico e cirúrgico dos pacientes. A alta perda de seguimento ambulatorial causa preocupação, porém reflete as dificuldades próprias de serviços de saúde de países em desenvolvimento. / Congenital heart diseases are the most common serious congenital malformations, affecting two of three children per 100 newborns, the atrioventricular septal defect (AVSD) is responsible for 5% of these cases, reaching almost 50% of bearers of Down\'s Syndrome.

This research aimed to analyze the prevalence of pulmonary hypertension diagnosed by transthoracic echocardiogram and identify risk factors for this outcome in patients undergoing surgical correction of AVSD in the last 16 years at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP - USP). All patients diagnosed with AVSD, submitted to surgical correction and followed at the HCFMRP - USP in the last 16 years and were selected. Those who had systolic pulmonary arterial pressure above 30 mmHg in the echocardiogram evaluation were considered to have pulmonary hypertension. Clinical variables before and after surgery were analyzed. Anthropometric and age data at the surgery had no influence in the presence of PH in the follow up. Although prolonged cardiopulmonary bypass and pulmonary mechanical ventilation had significantly affected that outcome. The survival had increased significantly in the last eight years of our study, reflecting the improvement of assistance. A high loss of follow up was detected and made us very concerned, however shows the difficulties and low investment in the public health system in developing countries.

Toda cirurgia implica em lesão de tecidos, manipulação de estruturas e órgãos, sendo a dor uma conseqüência desse processo, que pode, porém, ser minimizada. O presente estudo tem como objetivos caracterizar o processo de manejo da dor aguda na criança no período pós-operatório a partir dos registros contidos nos seus prontuários, identificar como as enfermeiras cuidam das crianças com dor no período pós-operatório e quais fatores influenciam sua prática. Para tanto, foram analisados, retrospectivamente, os registros sobre dor pós-operatória de 300 prontuários de 280 crianças de 0 a 14 anos submetidas à cirurgia no ano de 2004 em três hospitais de uma cidade do interior do Paraná. Também foram ouvidas, por meio de entrevista, as 15 enfermeiras que trabalhavam nas unidades pediátricas dos três hospitais. A caracterização do manejo da dor a partir dos registros dos prontuários indicou a existência de poucos registros sobre dor pós-operatória realizados por enfermeiras, sendo que a grande maioria deles foi realizada por auxiliares ou técnicos de enfermagem, com alguma variação entre os hospitais pesquisados. Procedeu-se a análise qualitativa dos dados, os quais foram agrupados ao redor de três temas: as experiências de dor e suas repercussões; a atuação da enfermeira no manejo da dor pós-operatória; formação, aquisição e disseminação de conhecimentos sobre dor pediátrica. O estudo mostrou que as enfermeiras avaliam a dor pós-operatória de forma assistemática e, em geral, limitam-se ao controle farmacológico da dor. Realizam o manejo da dor na dependência da conduta e prescrição médicas, utilizando forma limitada as estratégias não-farmacológicas de alívio. Demonstraram interesse em ampliar seus conhecimentos na área e na formação de grupos de dor nas instituições em que trabalham. Consideramos que os resultados do estudo podem provocar a discussão do tema nos hospitais pesquisados e, numa visão otimista, podem contribuir para deflagrar e estimular a implementação da avaliação sistematizada da dor em crianças e adolescentes nesses locais. / ABSTRACT TACLA, T. G. M. Care of children with post-operative pain: Pediatric nurses experiences. 2006. 251p. PhD Dissertation ¾ Escola de Enfermagem de Ribeirão Preto. Universidade de São Paulo, 2006. All surgical procedures involve tissue lesions, manipulation of structures and organs, causing pain which can be minimized during the process. The objectives of this study are to characterize the process of managing post-operative acute pain in children based on their medical records, to identify how nurses care for children in pain during the post-operative period, and which factors affect their practices. The study evaluated 300 medical records on post-operative pain of 280 children, 0-4 y. o., who underwent surgery in 2004, in 3 hospitals located in a city in the interior of the state of Paraná. An interview with 15 nurses who worked in the Pediatric Ward of these hospitals was also carried out. Characterization of pain management from the medical records revealed that only a few nurses make notes of post-operative pain, and that the majority of the records were made by nursing aides and technicians, with some variations among the researched hospitals. Data were analyzed qualitatively and grouped into three topics: the experiences of pain and its consequences, nurses? performance during post-operative pain management, and pediatric pain knowledge development, acquisition and dissemination. Results from the study showed that nurses evaluate post-operative pain a-systematically, which, in general, is limited to pharmacological pain control. Their management depends on the doctor?s prescription, thus using limited non-pharmacological pain-relief strategies. They show interest in broadening their knowledge in the area and in developing pain groups in their institutions. We believe that the results from this study may generate a discussion on the topic in these hospitals, and, consequently, contribute to the implementation of a systematic evaluation of pain in children and adolescents in these places.

A fibrilação atrial (FA) é a arritmia mais comum no pós-operatório de cirurgia cardíaca. Apesar de estar relacionada a alterações estruturais, alguns pacientes, mesmo que sem tais condições, ainda assim, cursam com fibrilação atrial no pós-operatório (FAPO) causando aumento no tempo de internação e custos. Estudos recentes vem ampliando o conhecimento sobre pequenos fragmentos de RNA, chamados de microRNAs (miRNAs) que podem interferir diretamente no aparecimento de algumas doenças na área cardiovascular. O objetivo do presente estudo é: 1) comparar a expressão dos miRNAs 1, 23 e 26 entre pacientes com e sem FAPO; 2) comparar nos grupos a expressão destes miRNAs entre os período pré e pós-cirúrgico; 3)comparar a expressão dos genes GJA1, KCNJ2, CACNB1, CACNA1C e KCNN3 entre os tempos pré e pós-cirúrgico no grupo FAPO; 4) comparar estes últimos genes no tecido atrial; 5) comparar os genes relacionados à produção de interleucinas (IL)-1, 6 e fator de necrose tumoral alfa (TNF?) entre os grupos e entre os tempos pré e pós-cirúrgico; 6)avaliar as características clínicas e evolutivas da população estudada. Pacientes submetidos à cirurgia de revascularização miocárdica foram submetidos à coleta de 20ml de sangue pré e pós-cirurgia bem como fragmento de tecido atrial. Um total de 143 pacientes compuseram os grupos: FAPO (24 pacientes), controle genético (24 pacientes) e controle total (97 pacientes + 24 grupo controle genético). Do ponto de vista clínico observou-se maior idade, tempo de anóxia, tempo de internação em terapia intensiva e hospitalar no grupo FAPO. A análise genética revelou menor expressão do miRNA-23 no grupo FAPO (p=0,02). A comparação entre os períodos pré e pós-cirúrgico revelou redução dos três miRNAs no tempo pós-cirúrgico (p<0,05) e dos genes relacionados às proteínas de canal (p<0,05). A comparação no tecido não evidenciou alterações entre os grupos. Os genes relacionados ás citocinas revelaram redução no período pós-cirúrgico (p<0,05) em ambos os grupos. Concluiu-se que o miRNA-23 pode ter implicação no surgimento da FAPO e outros miRNAs não estudados devem estar envolvidos neste processo uma vez que houve redução de outros genes de canais relacionados ao aparecimento de FAPO. / Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery. AF is related to cardiac structural changes although a group of patients still remains developing post-operative atrial fibrillation (FAPO) even without those changes, leading to more days in the hospital and costs. Recent studies showed that short fragments of RNA, called microRNA (miRNA) can contribute to the development of several diseases in the cardiovascular area. The aim of this study is to 1) compare the expression of miRNA-1, 23 and 26 between the group with and without FAPO; 2) compare, in the FAPO group, the expression of these miRNAs in the pre and post-surgery periods; 3) compare the expression of GJA1, KCNJ2, CACNB1, CACNA1C e KCNN3 genes between the pre and post-surgery periods; 4) compare this genes in atrial tissue; 5) compare the genes related to inflammation cytokines as interleukin(IL)-1, 6 and alpha tumoral necrosis factor between the groups in the pre and post-surgery periods; 6) evaluate clinical and evaluative patterns of the study population. Twenty milliliters of blood samples in the pre and post-operative periods and an atrial fragment were extracted from patients submitted to coronary artery bypass graft surgery. A total of 143 patients were divided in the FAPO group (24 patients), genetic control group (24 patients) and a total control (97 + 24 genetic control patients). The clinical analysis showed bigger age and clamp-time, more days in the intensive care unit and hospital in the FAPO group. The genetic analysis revealed less expression of miRNA-23 in the FAPO group (p=0.02). The comparison between the pre and post-surgery periods showed reduction in the three studied miRNAs (p<0.05) and reduction in the genes related to the production of the membrane protein channel sites. The comparisons in the atrial tissue didn´t show any difference in the study groups. The cytokines showed post-surgery reduction (p<0.05) in both groups. The conclusion is that miRNA-23 can be implicated in FAPO as others miRNAs not studied can also be, once there was a significative reduction in the genes related to FAPO development.

Among the nurses' activities, discharge planning is an important step in the systematization of nursing care. This study aimed identify the orientation needs felt by orthopedic surgical patients at hospital discharge, to know the patients´ feelings about receiving orthopedic discharge, to know the patients' perceptions of the guidelines received at discharge, to identify the professional involved in the process of orientation of discharge and to contribute to the construction of guideline to be made available to the patient and his family in the moment of discharge. Twenty patients submitted to orthopedic surgery participated in an oral interview, which was recorded in audio, guided by a script of guiding questions and a form with clinical and socio-demographic data. The content of the interviews was organized according to the reference of the Discourse of the Collective Subject and for the analysis and interpretation of these data the content analysis in thematic analysis mode was used. OREM Self-Care Theory was used for the categorization of orientation needs. Clinical and socio-demographic data were analyzed according to the frequency of their variables. The results showed that the profile of the participants is composed mainly of men, aged between 18 and 45 years, married and with full secondary education. The SUS was the prevalent health agreement and osteosynthesis was the most frequent procedure. Happiness was the main feeling related to hospital discharge. The most mentioned doubts and orientation needs were all about rehabilitation, illness/accident insurance and recovery time. The guidelines were based on universal self-care requisites (feeding, hydration, hygiene, dressing protection), health deviation in self-care requisites (rehabilitation, rest, dressing, movement, return, hand positioning, medication, intercurrence, treatment of another fracture) and developmental self-care requisites (recovery time). The guidelines were offered mainly by a physician, accompanied or not by a nurse, evidencing the absence of systematization in the discharge planning and the predominantly clinical focus of these guidelines. The survey of the orientation needs of the interviewees supported the elaboration of infographic to advise the verbal guidelines offered at the time of discharge and to be consulted at home. Our expectation that the results of the study contribute to the professionals involved in the discharge process, so that they may rethink their practices considering, above all, the systematized discharge plan / O planejamento de alta se dá a partir das necessidades do paciente, incluindo suas necessidades de aprendizado, abrangendo o período compreendido entre o momento da admissão até o momento da alta hospitalar, com abordagem multiprofissional. Dentre as atividades do enfermeiro, o planejamento de alta é etapa importante da sistematização da assistência de enfermagem. O estudo teve como objetivos conhecer os sentimentos de pacientes submetidos a cirurgia ortopédica ao receber alta hospitalar, identificar as necessidades de orientação sentidas por esses pacientes, conhecer suas percepções sobre as orientações recebidas durante a alta hospitalar, identificar o (s) profissional (is) envolvidos no processo da orientação de alta e construir coletivamente um material didático a ser disponibilizado ao paciente e sua família no momento de alta. Foram sujeitos da pesquisa 20 pacientes submetidos à cirurgia ortopédica que participaram de uma entrevista oral, gravada em áudio, orientada por um roteiro de questões norteadoras e de um formulário com dados clínicos e sócio demográficos. O conteúdo das entrevistas foi organizado segundo o referencial do Discurso do Sujeito Coletivo e para análise e interpretação desses dados foi utilizada a análise de conteúdo, modalidade análise temática. Para a categorização das necessidades de orientação foi utilizada a Teoria do Autocuidado de OREM. Os dados clínicos e sócio demográficos foram analisados segundo a frequência de suas variáveis. Os resultados mostraram que o perfil dos participantes é composto majoritariamente de homens, com idade entre 18 e 45 anos, casados e com ensino médio completo. O SUS foi o convênio de saúde prevalente assim como as osteossínteses foram os procedimentos mais frequentes. Felicidade foi o principal sentimento relacionado a alta hospitalar. As dúvidas e necessidades de orientação mais referidas foram alusivas a reabilitação, auxílio doença/seguro por acidente e tempo de recuperação. As orientações recebidas versaram sobre requisitos de autocuidado universais (alimentação, hidratação, higiene, proteção do curativo), requisitos de autocuidado nos desvios de saúde (reabilitação, repouso, curativo, movimentação, retorno, posicionamento da mão, medicação, intercorrência, tratamento de outra fratura) e requisitos de autocuidado desenvolvimentista (tempo de recuperação). As orientações foram ofertadas principalmente pelo médico, em conjunto ou não com o enfermeiro evidenciando a ausência de sistematização no planejamento de alta e o enfoque predominantemente clínico dessas orientações. O levantamento das necessidades de orientação dos entrevistados subsidiou a construção de um infográfico para assessorar as orientações verbais ofertadas no momento da alta e para ser consultado em casa. Esperamos que os resultados do estudo contribuam para que os profissionais envolvidos no processo de alta repensem suas práticas considerando, sobretudo, o planejamento sistematizado de alta

Masters of Science - Msc (Physiotherapy) / Post-operative physiotherapy plays a vital role in the management of patients with incontinence in order to optimise the outcome of obstetric fistula surgery. Women who suffer residual urinary incontinence continue to experience shame, social isolation and institutional rejection. Incontinence continues to impair them leading to lower levels of role participation and restriction in most activities. Gynocare Fistula Center, Eldoret, receives a number of referrals for women with obstetric fistula requiring surgical and physiotherapy care. Many studies have focused on the determinants of surgical outcomes and social reintegration but none have focused on woman's perceptions and experiences with postoperative physiotherapy. While continence is not always achieved immediately after surgery, this study was designed to explore women's perceptions and experience of postoperative physiotherapy management at an obstetric fistula center in Eldoret,Kenya. Participants were then asked about their experiences and related perceptions and perceived challenges regarding the physiotherapy service following discharge from the Center. An explorative qualitative method was used to explore the women's perceptions and experiences of the post-operative physiotherapy management, as well as their perceived challenges regarding access to physiotherapy post discharge.

Pointed out this complexity, several studies are focused on understanding how these can best treated by surgical procedures that could be less harmful to the patient. Invasive mechanical ventilation is one of the major supporting at the time of performing such procedures, but this could be one of the greatest complications at the time of the patient´s evolution in the ICU environment, since the moment of its withdrawal depends on many factors. Objective: The aim of this study was to evaluate whether the time required for a safety extubation following the surgical procedure would be associated to the complexity of the preoperative cardiopathy. Methodology: A total of 352 medical records of patients from a three-year period who had undergone surgery and maintained in the ICU were investigated . They were divided into two groups: neonates and non-neonates. To perform the statistical tests, six groups were created for evaluation among them, according to the degree of complexity. Rachs-1 Cardio-Surgical Risk assessment was taken into account to observe each patient´s degree of complexity. Results: Non-Neonates: Discrete male predominance in the period. When we compared the mortality according to the increase in the complexity, we could observe a statistically significant difference in four of the six evaluated groups, as well as the intubation time length , which was higher as the complexity of heart diseases increased. Regarding the estimative lines of intubation time, the best correlation was the polynomial with a 0.84-correlation coefficient, which could be feasible at the moment to evaluate intubation time. Neonates: Predominance of male sex. There was no significant difference in relation to mortality according to Rachs-1, as well as the intubation length of time. Thus, there was no statistically significant difference between the samples; this demonstrated that there was no increase in time length as the complexity increased. CONCLUSION: After assessing data and comparing them with the ones from the literature, we could conclude that the time length of patients´ intubation in the postoperative period of cardiac surgery is directly related to the complexity of the heart failure to be corrected; except in newborns from this evaluated group. The extubation time length behaved polynomially, and could be feasible to predict the patient´s extubation. Regarding the deaths, there is a relationship with a higher number according to the increase of the complexity of the heart failures, but no relationship was observed according to the case of the newborns. / As Cardiopatias Congênitas apresentam-se como um grupo de afecções que respondem por um grande número de óbitos. Levando-se em consideração esta complexidade, várias são as pesquisas com foco no entendimento de como estas cardiopatias podem ser mais bem tratadas, a partir de procedimentos cirúrgicos que se apresentam menos lesivos ao paciente. Um dos maiores aliados no momento da realização de procedimentos de grande porte como tal, é a ventilação mecânica invasiva. No entanto, este auxílio pode ser um dos maiores complicadores no momento da evolução do paciente no ambiente de UTI, pois o momento da sua retirada depende de muitos fatores. OBJETIVO: O objetivo deste trabalho foi avaliar se o tempo necessário para a realização da extubação com segurança do paciente, após a realização do procedimento cirúrgico, estaria ligado à complexidade da cardiopatia pré-operatória. METODOLOGIA: Foram investigados prontuários de 379 pacientes de um período de três anos, os quais passaram por cirurgia e estiveram na UTI. Foram divididos em dois grupos: neonatos e não neonatos. Para a realização dos testes estatísticos foram gerados seis grupos para avaliação entre eles, de acordo com o grau de complexidade. Levou-se em consideração a avaliação de Risco Cárdio-Cirúrgico Rachs-1 para constatação do grau de complexidade de cada paciente RESULTADOS: Não Neonatos: Discreta predominância do sexo masculino no período. Quando comparamos a mortalidade de acordo com o aumento da complexidade, pudemos observar diferença estatisticamente significante em quatro dos seis grupos, bem como, o tempo de intubação, que foi maior conforme o aumento da complexidade das cardiopatias. Com relação às linhas de estimativa de tempo de intubação, observou-se que a melhor correlação foi a polinomial com coeficiente de correlação de 0,84, podendo ser útil no momento da avaliação de tempo de intubação. Neonatos: Predomínio do sexo masculino. Não houve diferença significante com relação à mortalidade de acordo com o Rachs-1, bem como o tempo de intubação. Assim, sem diferença estatística considerável entre as amostras, o que demonstrou não haver aumento de tempo de acordo com o aumento da complexidade. CONCLUSÃO: Após a avaliação dos dados e confrontá-los com dados da literatura, concluiu-se que o tempo de intubação em pacientes no pós-operatório de cirurgia cardíaca está diretamente ligado à complexidade da cardiopatia a ser corrigida; exceto em pacientes recém-nascidos no grupo avaliado. O tempo até a extubação comportou-se de forma polinomial, podendo ser útil na predição para uma possível extubação do paciente. Com relação aos óbitos observamos que existe associação com o maior número de acordo com o aumento da complexidade das cardiopatias, porém, mais uma vez, no caso dos recém-nascidos não foi observada relação.

Post-operative ileus (POI) is the functional inhibition of propulsive intestinal motility which is a frequent occurrence following abdominal surgery in the horse and in humans. Rodent and human-derived data have shown that manipulation-induced activation of the resident muscularis externa (ME) macrophages in the intestine contributes to the pathophysiology of the disease. Most studies of the disease, specifically in the horse, have focussed on identification of risk factors, descriptive studies of the disease or the assessment of the efficacy of various therapeutic and prophylactic interventions. As a result, the proposed pathogenesis of equine POI is largely reliant on the translation of data from rodent models. The aims of this thesis were to identify macrophage populations in the normal equine gastrointestinal tract (GIT) and to study equine macrophage activation by stimulating equine bone marrow-derived macrophages (eqBMDMs) with lipopolysaccharide (LPS) as a model for intestinal macrophage activation. Firstly, the normal population of macrophages in the equine GIT was determined. Using CD163 as an immunohistochemical marker for macrophages. CD163+ve cells were present in all tissue layers of the equine intestine: mucosa, submucosa, ME and serosa. CD163+ve cells were regularly distributed within the ME, with accumulations adjacent to the myenteric plexus, and therefore to intestinal motility effector cells such as neurons and the Interstitial Cells of Cajal. The differentiation and survival of intestinal macrophages depends upon signals from the macrophage colony-stimulating factor (CSF-1) receptor. LPS translocation from the gut lumen is thought to be a key activator of ME macrophages. To provide a model for gut macrophages, a protocol was optimised to produce pure populations of equine bone marrow-derived macrophages (eqBMDMs) by cultivation of equine bone marrow in CSF-1. Macrophage functionality was assessed using microscopy, flow cytometry and phagocytosis assays. EqBMDMs responded to LPS stimulation with increases in expression of positive control genes, tumour necrosis factor alpha (TNF-α) and Indoleamine 2,3-dioxygenase (IDO1). The same mRNA was subjected to transcriptomic (RNA-Seq) analysis. Differential gene expression and network cluster analysis demonstrated an inflammatory response characterised by the production of pro-inflammatory cytokines such as interleukin 1 beta (IL-1β) and interleukin 6 (IL-6). However, in contrast to rodent macrophages, eqBMDMs failed to produce nitric oxide in response to LPS, showing species-specific variation in innate immune biology. Using these data, we compared gene expression in normal equine intestine and in intestine from horses undergoing abdominal surgery for colic (abdominal pain). Horses undergoing abdominal surgery showed evidence of increased expression of IL-1β, IL-6 and TNF-α in the mucosa and ME when compared to control tissue. Horses with post-operative reflux (POR), a clinical sign of POI, had increased gene expression of IL-1β, IL-6 and TNF-α compared to horses that did not develop POR following abdominal surgery. These preliminary data suggest that there is macrophage activation within the ME of the intestine during abdominal surgery in the horse, and that a greater activation state is present in horses that subsequently develop POR. The final part of this study was to investigate the effect of a long-acting form of CSF- 1, an Fc fusion protein (CSF1-Fc), as a potential treatment for POI using a mouse model. This work, performed in collaboration with another research group, found that mice lacking the C-C chemokine receptor type 2 (CCR2) gene, which is required for monocyte recruitment into tissues, had a longer recovery period following intestinal manipulation (IM) than wild type (WT) mice. With the administration of CSF1-Fc, infiltration of neutrophils to the ME was reduced and the number of macrophages in the ME was increased in both WT and CCR2-/- mice following IM. Administration of CSF1-Fc in CCR2-/- mice improved recovery of gastrointestinal transit three days following IM, to the same extent as WT mice. Network cluster analysis and RT-qPCR of the ME revealed clusters of genes induced and downregulated by CSF1-Fc, with increased expression of anti-inflammatory and pro-resolving genes after IM in WT and CCR2-/- mice following treatment with CSF1-Fc.

<p>Post-operative sore throat is a common minor complication following general anaesthesia via endotracheal intubation. Pharyngeal packing has often been implicated in this minor anaesthetic complication. In maxillo-facial and oral surgery, two types of throat packs are commonly used namely ribbon gauze and tampons. In order to establish the efficacy of these two types of throat packs a prospective, randomised, clinical study was conducted. The objectives of the study were threefold: to investigate the effect of the two different types of throat packs on the incidence of post-operative sore throat, to determine the quality of seal provided by the two different types of throat packs and finally, to formulate a faculty protocol. The study consisted of 70 patients undergoing third molar surgery. All the patients were intubated via endotracheal intubation and had a throat pack placed. Patients were also randomly selected and allocated to two groups. One group had ribbon gauze while the other group had a tampon as a throat pack. The study reflected no statistically significant difference in the incidence of postoperative sore throat between the two groups. It was interesting to note that the symptoms of sore throat resolved quicker with the use of tampons. On the other hand, the ribbon gauze provided a better pharyngeal seal.</p>

Patients were also randomly selected and allocated to two groups. One group had ribbon gauze while the other group had a tampon as a throat pack. The study reflected no statistically significant difference in the incidence of postoperative sore throat between the two groups. It was interesting to note that the symptoms of sore throat resolved quicker with the use of tampons. On the other hand, the ribbon gauze provided a better pharyngeal seal.</p>
