Perinatal outcome and risk factors of precipitate labor in term primipara: an analysis of 381 cases / 浙江大学学报·医学版

OBJECTIVE@#To investigate the perinatal outcome and risk factors of precipitate labor in term primipara.@*METHODS@#A total of 6951 full-term singleton primiparas with cephalic vaginal delivery in Women's Hospital, Zhejiang University School of Medicine from January 2020 to December 2020 were enrolled, among whom 381 cases of precipitate labor were classified as the precipitate labor group and 762 cases of normal labor were randomly selected as the control group. The perinatal outcomes of the two groups were compared, and the risk factors of precipitate labor were analyzed by multivariate logistic regression.@*RESULTS@#The incidence of precipitate labor in full-term, singleton pregnancy and cephalic primiparas was 5.48% (381/6951). The durations of the first and second stages of labor in the precipitate labor group were significantly shorter than that in the control group ( P<0.01); while there was no significant difference in the duration of the third stage of labor between the two groups ( P>0.05). Compared with the control group, the incidence of soft birth canal laceration in the precipitate labor group was increased ( P<0.01). However, there was no significant difference in postpartum hemorrhage and neonatal related perinatal outcomes between the two groups (all P>0.05). Multivariate logistic regression analysis showed that maternal height ( OR=1.038, 95% CI: 1.010-1.067, P<0.01), gestational age at delivery ( OR=0.716, 95% CI: 0.618-0.829, P<0.01), late miscarriage ( OR=1.986, 95% CI: 1.065-3.702, P<0.05), membrane rupture before labor ( OR=1.802, 95% CI: 1.350-2.406, P<0.01), labor induction by transcervical balloon ( OR=3.230, 95% CI: 2.027-5.147, P<0.01), labor induction by propess ( OR=2.332, 95% CI: 1.632-3.334, P<0.01) and labor induction by oxytocin ( OR=0.291, 95% CI: 0.219-0.386, P<0.01) were independently associated with precipitate labor.@*CONCLUSIONS@#The incidence of precipitate labor in full-term, singleton pregnancy was not low. Precipitate labor could lead to a significant increase in perineal laceration. Maternal height, history of late miscarriage, membrane rupture before labor and labor induction by transcervical balloon, labor induction by propess are risk factors, while labor induction by oxytocin and late gestational time of delivery are protective factors for precipitate labor in term primipara.

Perineal Lacerations: A Retrospective Study in a Habitual-Risk Public Maternity / Lacerações perineais: um estudo retrospectivo em uma maternidade pública de risco habitual

Abstract Objective In around 85% of vaginal births, the parturients undergo perineal lacerations and/or episiotomy. The present study aimed to determine the incidence of lacerations and episiotomies among parturients in 2018 in a habitual-risk public maternity hospital in southern Brazil, and to determine the risk and protective factors for such events. Methodology A retrospective cross-sectional study. Data were obtained from medical records and analyzed using the Stata software. Univariate and multivariate logistic regressions were performed. Values of p<0.05 were considered significant. Results In 2018, there were 525 vaginal births, 27.8% of which were attended by obstetricians, 70.7% by obstetric nurses, and 1.5% evolved without assistance. Overall, 55.2% of the parturients had some degree of laceration. The professional who attended the birth was a significant variable: a greater number of first- and second-degree lacerations, as well as more severe cases, occurred in births attended by nurses (odds ratio [OR]: 2,95; 95% confidence interval [95%CI]: 1,74 to 5,03). Positions at birth that did not enable perineal protection techniques (expulsive period with the "hands-off" method), when analyzed in isolation, determined the risk; however, in the final regression model, this relationship was not confirmed. Although reported in the literature, there were no associations between the occurrence of laceration and age, skin color, or birth weight. In 24% of the births, episiotomy was performed, and doctors performed 63.5% of them. Conclusion Births attended by nurses resulted in an increased risk of perineal lacerations, of varying degrees. In turn, those assisted by physicians had a higher occurrence of episiotomy.

Resumo Objetivo Aproximadamente 85% dos partos vaginais cursam ou com lacerações perineais e/ou com episiotomia. Este estudo objetivou determinar a incidência de lacerações e episiotomias das parturientes de 2018 de uma maternidade pública de risco habitual, no sul do Brasil, bem como determinar os fatores de risco e proteção para tais eventos. Métodos Estudo transversal retrospectivo, no qual os dados foram obtidos dos prontuários e analisados no programa Stata. Realizaram-se regressões logísticas uni e multivariada. Foram considerados como significantes valores de p<0,05. Resultados Em 2018, aconteceram 525 partos vaginais, sendo 27,8% assistidos por médicos obstetras, 70,7%, por enfermeiros obstetras, e 1,5% evoluíram sem assistência. Ao todo, 55,2% das parturientes apresentaram algum grau de laceração. O profissional que assistiu ao parto foi uma variável que demonstrou significância: um maior número de lacerações de primeiro e segundo graus, bem como casos de maior gravidade, ocorreram em partos assistidos por enfermeiros (razão de probabilidades [RP]: 2,95; intervalo de confiança de 95% [IC 95%]: 1,74 a 5,03). Posições ao nascimento que não permitiam técnicas de proteção perineal (período expulsivo na técnica "sem mãos" [hands off, em inglês]), quando analisadas isoladamente, determinaram o risco; contudo, no modelo final de regressão, essa relação não se confirmou. Apesar de relatada na literatura, não houve associação entre a ocorrência de laceração e a idade, a cor da pele, ou o peso de nascimento. Em 24% dos partos, uma episiotomia foi realizada, tendo os médicos executado 63,5% delas. Conclusão Partos assistidos por enfermeiros resultaram em um maior risco de lacerações perineais, de variados graus. Por sua vez, os assistidos por médicos apresentaram maior ocorrência de episiotomia.

Tratamiento del cuerpo extraño rectal en un Servicio de Urgencia / Rectal foreign body treatment at an urgency service

Resumen Introducción: El cuerpo extraño rectal (CER) es un problema de difícil manejo para el cirujano general. La vía anal es la puerta de entrada más habitual seguido de la oral. La sospecha clínica es fundamental para el diagnóstico, pudiendo apoyarse de imágenes. El tratamiento es su extracción por vía transanal o por vía anterior. Objetivos: Caracterizar, describir y presentar el tratamiento de los pacientes con CER que consultaron en urgencia del Hospital el Pino (HEP) entre los años 2011 y 2016. Material y Método: Estudio serie de casos. Se realiza revisión de fichas clínicas de pacientes con CER en un periodo de 5 años en el Servicio de Urgencia del HEP. Se identificó a los pacientes tratados en box y a aquellos tratados en pabellón. Se caracterizó según variables demográficas, tratamiento, complicaciones y días de hospitalización. Resultados: Se identificaron 18 pacientes, 13 hombres y 5 mujeres de 45 años (± 36-51) y 34 años (± 23-64) respectivamente. En 1 de ellos fue posible extracción manual transanal en box sin anestesia y en 17 se requirió tratamiento en pabellón, donde 12 fue por vía transanal y 5 por abordaje abdominal. En ningún caso se identificó lesión intestinal. Evolución postoperatoria adecuada. Días de hospitalización promedio 1,8 días. Conclusión: Este es un problema infrecuente y de difícil manejo. Existe mayor frecuencia en hombres de edades media siendo la puerta de entrada la vía anal en todos los casos. En la mayoría se requirió extracción en pabellón bajo anestesia siendo el abordaje transanal el más utilizado y con buenos resultados.

Introduction: The rectal forcing body (RFB) is a problem which involves a difficult management for surgeons. Anal via is the most frequent entrance area, followed by the oral via. Clinical suspicion is fundamental for diagnosis and it is possible to support it using imaging. Treatment considers extraction through transanal or frontal via. Aim: To describe and present the treatment of patients with rectal foreing body in the Urgency Service of El Pino Hospital during years 2011 to 2016. Materials and Method: Case studies. Clinical records revision of patients with rectal foreing body in the Urgency Service of El Pino Hospital considering a 5-year period. Patients are identified as those treated in the box and in a surgical pavilion. Patients were classified according to demographic variables, received treatment, associated complications and hospitalization time. Results: 18 patients are identified, 13 men and 5 women, 45 (± 36-51) and 34 (± 23-64) years respectively. It was possible to manually extract via trans-anal at box, in one of these cases; 17 of them required treatment at surgical pavilion, where 12 were via trans-anal and 5 via abdominal. None of these cases had intestinal injury. Post-surgery evolution was adequate. Average hospitalization was 1.8 days. Conclusion: RFB is a non-frequent problem which requires high diagnose suspicious to be able to carry out proper treatments. It is more frequent in middle age men, with transanal input. In most cases, the extraction was done in surgical pavilion and required anesthesia and were done via trans anal with good results.

Prevalence of high-grade perineal tear during labor in Mexican adolescents / Prevalencia de desgarro de alto grado en parto de adolescentes mexicanas

Abstract Introduction: There is a high rate of deliveries in adolescents in Mexico. This age group is vulnerable to obstetric complications, including lacerations of the anal sphincter. Objective: To determine the prevalence of third and fourth degree perineal tears in adolescents during childbirth, and to evaluate risk factors in comparison with deliveries with lacerations of adult women. Methods: All obstetric care episodes were reviewed from a public tertiary hospital data in Monterrey, Mexico in 2014. Age, primiparity, delivery instrumentation, episiotomy, body mass index, product weight and tear´s degree were documented at the deliveries with tears of third and fourth degree. Results: The prevalence of third and fourth degree tears of 2.0% was found in the general population, being adolescents the most affected with 2.5%. The unadjusted odds ratio of high-grade tears in adolescent females at delivery, compared to adult females, was 1.36 (95% CI = 0.99-1.86, p= 0.05). No difference was found when comparing risk factors among high-grade tear deliveries in adolescents versus adults. Conclusions: A higher prevalence than previous reported for high grade tears during delivery was found. The data suggest adolescence as a risk factor for high-grade tears during delivery.

Resumen Introducción: En México hay una elevada tasa de partos en adolescentes. Este grupo es vulnerable para complicaciones obstétricas, entre ellas laceración del esfínter anal. Objetivo: Conocer la prevalencia de desgarros perineales de tercer y cuarto grado en adolescentes durante el parto y evaluar factores de riesgo en comparación con partos con laceración de mujeres adultas. Métodos: Se revisaron todas las atenciones obstétricas en un hospital publico de tercer nivel en Monterrey, Nuevo León, México en el año 2014. Se documentó edad, primiparidad, instrumentación del parto, realización de episiotomía, índice de masa corporal, peso del producto y grado del desgarro en los partos que presentaron desgarros de tercer y cuarto grado Resultados: Se encontró una prevalencia general de 2.0% de desgarros de tercer y cuarto grado y en adolescentes de 2.5%. La razón de momios sin ajustar de desgarros de alto grado en mujeres adolescentes en comparación con mujeres adultas fue de 1.36 (IC 95%= 0.99-1.86, p= 0.05). No se encontró diferencia al comparar factores de riesgo entre los partos con desgarro de alto grado en adolescentes contra adultas. Conclusiones: Se encontró una prevalencia mayor a lo reportado de desgarros de alto grado durante el parto. Los datos sugieren a la adolescencia como factor de riesgo para desgarros de alto grado.

Perineal trauma in a low-risk maternity with high prevalence of upright position during the second stage of labor / Trauma perineal em uma maternidade de baixo risco com alta prevalência de parto vertical durante o período expulsivo

Abstract Objective Perineal trauma is a negative outcome during labor, and until now it is unclear if the maternal position during the second stage of labormay influence the risk of acquiring severe perineal trauma. We have aimed to determine the prevalence of perineal trauma and its risk factors in a low-risk maternity with a high incidence of upright position during the second stage of labor. Methods A retrospective cohort study of 264 singleton pregnancies during labor was performed at a low-risk pregnancymaternity during a 6-month period. Perineal trauma was classified according to the Royal College of Obstetricians and Gynecologists (RCOG), and perineal integrity was divided into three categories: no tears; first/ second-degree tears + episiotomy; and third and fourth-degree tears. A multinomial analysis was performed to search for associated factors of perineal trauma. Results From a total of 264 women, there were 2 cases (0.75%) of severe perineal trauma, which occurred in nulliparous women younger than 25 years old. Approximately 46% (121) of the women had no tears, and 7.95% (21) performed mediolateral episiotomies. Perineal trauma was not associated with maternal position (p = 0.285), health professional (obstetricians or midwives; p = 0.231), newborns with 4 kilos or more (p = 0.672), and labor analgesia (p = 0.319). The multinomial analysis showed that white and nulliparous presented, respectively, 3.90 and 2.90 times more risk of presenting perineal tears. Conclusion The incidence of severe perineal trauma was low. The prevalence of upright position during the second stage of labor was 42%. White and nulliparous women were more prone to develop perineal tears.

Resumo Objetivo O trauma perineal é um desfecho negativo durante o parto, e é incerto, até omomento, se a posiçãomaternal durante o período expulsivo pode influenciar o risco de evoluir com trauma perineal severo. Nós objetivamos determinar a prevalência de trauma perineal e seus fatores de risco em uma maternidade de baixo risco com alta prevalência de posição vertical durante o período expulsivo. Métodos Um estudo de coorte retrospectivo de 264 gestações únicas durante o trabalho de parto foi realizado durante 6 meses consecutivos. O trauma perineal foi classificado de acordo com o Royal College of Obstetricianns and Gynecologists (RCOG). A integridade perineal foi dividida em três categorias: períneo íntegro; trauma perineal leve (primeiro e segundo graus + episiotomia); e trauma perineal severo (terceiro e quarto graus). Uma análise multinomial foi realizada para buscar variáveis associadas ao trauma perineal. Resultados De um total de 264 mulheres, houve 2 casos (0,75%)de trauma perineal severo m nulíparas com menos de 25 anos. Aproximadamente 46% (121) das mulheres não tiveram trauma perineal e 7,95% (21) realizaram episiotomias mediolaterais. Não houve correlação do trauma perineal com a posição de parto (p = 0,285), tipo de profissional que realizou o parto (p = 0,231), recém-nascidos com 4.000 gramas ou mais (p = 0,672), e presença de analgesia de parto (p = 0,319). Uma análise multinomial evidenciou que mulheres brancas e nulíparas apresentaram, respectivamente, um risco 3,90 e 2,90 vezes maior de apresentar trauma perineal. Conclusão A incidência de trauma perineal severo foi baixa. A prevalência de parto vertical durante o período expulsivo foi de 42%. Mulheres brancas e nulíparas foram mais suscetíveis a apresentar trauma perineal.

Implementação de práticas assistenciais para prevenção e reparo do trauma perineal no parto / Implementación de prácticas asistenciales para la prevención y reparación de trauma perineal en el parto / Implementation of care practices to prevent and repair perineal trauma in childbirth

RESUMO Objetivos Implementar práticas assistenciais para prevenção e reparo do trauma perineal no parto normal. Métodos Estudo quase-experimental, realizado no Hospital da Mulher Mãe-Luzia, Macapá, AP. Realizaram-se 74 entrevistas com enfermeiros e médicos e 70 com puérperas, e analisaram-se dados de prontuários (n=555). O desenvolvimento da pesquisa se deu em três fases: pré-auditoria e auditoria de base (fase 1); intervenção educativa e implementação de boas práticas assistenciais (fase 2); auditoria pós-implementação (fase 3); a análise foi pela comparação das fases 1 e 3. Resultados Após a intervenção educativa, menos profissionais incentivavam puxos dirigidos, realizavam episiotomia e suturavam lacerações de primeiro grau; mais mulheres informaram que o parto foi em posição litotômica; mais registros nos prontuários indicaram o uso de Vicryl® na sutura da mucosa e pele. Conclusões A intervenção educativa melhorou os cuidados e os desfechos perineais, porém há lacunas na implementação das evidências e inadequações no manejo do cuidado perineal.

ABSTRACT Objective To implement care practices for perineal trauma prevention and repairing in normal birth. Method Quasi-experimental study conducted at Hospital da Mulher Mãe-Luzia, in Macapá, AP, Brazil. Seventy-four (74) nurses and obstetricians and 70 post-partum women were interviewed and the records of 555 patients were analyzed. The study was conducted in three stages: pre-audit and baseline audit (phase 1); educational intervention and implementation of best practices (phase 2); post-implementation audit (phase 3). Data was analyzed by comparison of the results of phases 1 and 3. Results Following the educational intervention, a lower number of health professionals encouraged directed pushing, performed episiotomies and repaired first-degree lacerations; more women reported lithotomy position; more patient records indicated the use of Vicryl™ to suture the perineal mucosa and skin. Conclusion The educational intervention improved birth care and perineal outcomes. Nevertheless, gaps were identified in the implementation of evidence, as well as inappropriate perineal care management

Flexor Digitorum Superficialis and Flexor Digitorum Profundus with separated sheaths, a new normal variation in human / Flexor superficial de la y Flexor profundo de los con vainas separadas, una nueva variación normal en humanos

Case description: A 25 years old man presented with a laceration on radial side of proximal phalanx of 4th finger (zone II flexor) which was due to cut with glass. Clinical findings: The sheaths of Tendons of flexor digitorum sperficialis and profundus were not the same and each tendon had a separate sheath. Treatment and outcome: The tendons were reconstructed by modified Kessler sutures, after 15 months the patient had a 30 degrees of extension lag even after physiotherapy courses. Clinical relevance: This is the first reported of such normal variation in human hand tendon anatomy.

Descripción del caso: Se presentó un hombre de 25 años con una laceración en la parte radial de la falange proximal del cuarto dedo de la mano (zona flexor II) causada por el corte con un vidrio. Hallazgos clínicos: Las cubiertas de los tendones del flexor digitorum sperficialis y profundus estaban separadas en diferentes cubiertas. Tratamiento y resultado: Los tendones se reconstruyeron por la suturas modificadas de Kessler. Después de 15 meses el paciente presentó una pérdida del 30% en la extensión , aun después de la fisioterapia. Relevancia clínica: Es el primer reporte de la variación en la anatomía de la mano.

Clinical characteristics and causality of eye lid laceration in Iran

The aim of this study was to assess the etiological characteristics and visual outcomes of ocular trauma with more attention to eyelid laceration. In a cross-sectional study, 98 cases of isolated traumatic eyelid laceration were consecutively studied and its epidemiology, etiology and association with visual outcome were evaluated. The findings of this study could be used to develop healthcare related precautions and work place safety recommendations. Of the 98 patients included in the study, men exhibited a greater vulnerability and they were mostly aged around 29 years old. In terms of the place of trauma, 42 [42.8%] cases occurred in the street, 29 cases [29.6%] occurred at home, and 18 cases [18.4%] occurred at the workplace, while 5 cases [5.1%] happened in entertaining environments like parks. For 3 patients [3%], the incident took place at a public pathway, and in 1 patient [1%], the case occurred at school. As the most common cause of trauma, 41 patients [41.8%] had an object hit their eyes. In addition, assaults were a major cause of injury. The right eye and the upper lid were also the most common sites of injuries. Although no blindness occurred due to trauma causing eyelid laceration, the visual outcomes were correlated with severity of the incident defined based on the presence of open globe injuries. This study could possibly highlight the risk factors of eyelid laceration and provide the healthcare community with the essential recommendations regarding the safety precautions in dangerous settings, including daily/routine work places

Subacute Course of Common Iliac Arterial Laceration in Lumbar Disc Surgery

Vascular injuries in lumbar disc surgery are serious complications which may be overlooked due to a broad range of clinical manifestations. It is important to be aware of the perioperative implications of this rare occurrence to lower mortality risk. A 20-yr-old man with a right L4-5 lumbar disc protrusion was operated on routinely under a surgical microscope. A bloody surgical field was noted temporarily during a discectomy along with a decreased blood pressure. After fluid resuscitation with an ephedrine injection, the bleeding soon stopped spontaneously and his vital signs were stabilized. Fifty hours after the operation, the patient showed signs of hypovolemic hypotension with abdominal distension. The right femoral artery pulsation was absent on palpation. An enhanced CT angiography revealed a retroperitoneal hematoma and obstruction of the left common iliac artery. An urgent laparotomy was done to repair the injured vessel by excision and interposition of a graft. The patient had an uneventful recovery.The subacute course of deterioration might have been due to intermittent blood leakage from the lacerated common iliac artery, which was sealed spontaneously. It is very important to pay close attention to post-surgical clinical manifestations to avoid a potentially fatal outcome in lumbar disc surgery.

Factors related to obstetric third and fourth degree perineal lacerations in a jamaican cohort / Factores relacionados con las laceraciones perineales obstétricas de tercer y cuarto grado en una cohorte de Jamaica

OBJECTIVES: The aim of this study was to identify significant and modifiable risk factors associated with obstetric third and fourth degree perineal lacerations and to produce recommendations that may reduce their morbidity and prevalence. METHODS: This is a retrospective case control study performed between March 2004 and March 2008. All patients diagnosed with third and fourth degree perineal lacerations were identified (cases) along with randomly assigned controls who delivered during the same time period. Nineteen cases and 38 controls were identified giving a total of 57 patients. Each patient's hospital record was collected and the data extracted. RESULTS: When analysed for weight greater than or equal to 3.5 kg versus birthweight of less than 3.5 kg, the difference between cases and controls was found to be statistically significant, with a p value of 0.012. Of the cases, 21% had an operative delivery (forceps or vacuum) whereas only 2.6% of the controls had an operative delivery. This was found to be statistically significant (p = 0.011). CONCLUSIONS: This study has shown that the two main factors related to the obstetric third and fourth degree perineal lacerations were babies weighing more than 3.5 kg and the use of forceps or vacuum to assist with deliveries. These high risk patients should be attended to by the most senior staff that is available.

OBJETIVOS: El objetivo de este estudio fue identificar factores de riesgo modificables y significativos asociados con las laceraciones perineales obstétricas de 3er y 4to grado, y producir recomendaciones que puedan reducir su morbilidad y prevalencia. MÉTODOS: Se trata de un estudio de caso control retrospectivo realizado entre marzo de 2004 y marzo de 2008. Todas las pacientes diagnosticadas con laceraciones perineales de 3er y 4to grado fueron identificadas (casos) con controles asignados de manera aleatoria, que tuvieron el parto en el mismo período de tiempo. Diecinueve casos y 38 controles fueron identificados, para un total de 57 pacientes. Se recogieron y se extrajeron los datos de las historias clínicas de cada paciente. RESULTADOS: Al analizárseles en términos de peso superior o igual a 3.5 kg frente a un peso al nacer por debajo de 3.5 kg, la diferencia entre los controles y los casos resultó ser estadísticamente significativa, con un valor p de 0.012. De los casos, el 21% tuvo un parto operativo (fórceps o vacío), mientras que sólo el 2.6% de los controles tuvo un parto operativo. Esto resultó ser estadísticamente significativo (p = 0.011). CONCLUSIONES: Este estudio ha demostrado que los dos factores principales relacionados con las laceraciones perineales obstétricos de 3er y 4to grado, eran bebés con un peso de más de 3.5 kg y el uso de fórceps o vacío en la asistencia a los partos. Estos pacientes de alto riesgo deben ser atendidos por el personal disponible de mayor experiencia.

Laceração traqueal pós-intubação: análise de três casos e revisão de literatura / Post-intubation tracheal injury: report of three cases and literature review

A laceração traqueal pós-intubação é uma complicação rara e potencialmente fatal. Entre as principais causas, se destacam a hiperinsuflação do balonete e tentativas repetidas de intubação em situações de emergência. O diagnóstico depende da suspeita clínico-radiológica e da confirmação por fibrobroncoscopia. O manejo pode ser conservador ou cirúrgico, e essa opção depende de fatores do paciente (comorbidades, estabilidade ventilatória), das características da lesão (tamanho e topografia) e do tempo decorrido até o diagnóstico. O presente estudo relata três casos de laceração traqueal decorrente de trauma de intubação com dois pacientes submetidos a tratamento operatório e um deles ao tratamento conservador.

Post-intubation tracheal injury is a rare and potentially fatal complication. Among the most common causes, cuff overinflation and repetitive attempts of orotracheal intubation in emergency situations are paramount. Diagnosis is based on clinical and radiological suspicion, confirmed by fiberoptic bronchoscopy. Both conservative and surgical management apply, and the decision-making process depends on the patient profile (comorbidities, respiratory stability), characteristics of the lesion (size and location) and the time elapsed between the occurrence of the injury and the diagnosis. We report the cases of three patients presenting tracheal laceration due to traumatic orotracheal intubation, two submitted to surgical treatment and one submitted to conservative treatment.

Anatomia, fisiologia e importância clínica do corpo perineal / Anatomy, physiology and clinical importance of the perineal body

O corpo perineal feminino é uma estrutura de interconecção para componentes musculares, fasciais e fibrosos, medindo cerca de 2 cm de diâmetro, situado em posição mediana, entre o ânus e a vagina. É também o ponto de conexão dos mecanismos de continência fecal e urinária. A função do corpo perineal é dar suporte da região anorretal à pelve e da vagina à fáscia pélvica, prevenir a expansão do hiato urogenital, funcionar como barreira entre vagina e reto e preservar a continência urinária e fecal. É importante na obstetrícia, pois pode ser lesado durante o parto vaginal e geralmente é mal reparado, devido ao desconhecimento de sua anatômia; é o local onde o cirurgião realiza a episiotomia com risco de lesão ao nervo pudendo durante o parto. A revisão sistemática deste assunto evidenciou que a massagem protege do trauma e que a episiotomia não deve ser usada como rotina. Para assegurar um atendimento obstétrico e ginecológico de qualidade é necessário ter um conhecimento adequado da anatomia pélvica, das indicações corretas da episiotomia e da importância clínica do corpo perineal.

This case is reported to highlight the possiblitity of a serious fatal internal injury without significant external injury in the chest.

Effect of episiotomy on perineal lacerations in spontaneous vertex deliveries

To evaluate the effects of episiotomy on the frequency of perineal lacerations. Cross-Sectional analytical study. Department of Gynae Obstetrics unit III. Lady willingdon Hospital Lahore. From April 1994 to March 1996. 2918 women who delivered vaginally were included in the study. Only right mediolateral episiotomy incision was used in these cases. Local anaesthesia in the form of 2% Lignocain was used in all cases to infiltrate the area before episiotomy cut. The delivery was conducted in most cases by a resident. The rate of perineal lacerations with or without episiotomy in both primiparae and multiparae groups was noted. Results 2918 women of term singleton babies were entered into this study. Episiotomy was performed in 1419 [48.63%] of these women. There were 1095[37.53%] primiparae and 1823 [62.47%] multiparae in the study groups. The rate of episiotomy in primiparae and multiparae were 93.42% and 21.72% respectively. A total of 267 [9.2%] perineal tears were sustained by these women during vaginal delivery. Episiotomy was associated with 151 [10.6%] perineal tears compared to 116[7.7%] without episiotomy. The incidence of fourth degree perineal laceration was 0.4% without episiotomy but increased to 1% with the use of episiotomy. This difference is statistically significant. Episiotomy is not protective against severe perineal lacerations. A selective use of episiotomy is recommended for appropriate indications

Laceration of the posterior inferior cerebellar artery by suboccipital puncture of the cisterna magna: case report

Relatamos o caso de um homem de 27 anos que procurou o pronto atendimento de um hospital com cefaléia intensa, vômitos e um episódio de perda de consciência. Uma tomografia de crânio foi normal e o paciente foi dispensado. Dez horas após, o paciente procurou o setor de emergência do nosso hospital com as mesmas queixas. Uma punção suboccipital tecnicamente dificultada pela ansiedade do paciente que se movimentou durante a coleta foi realizada evidenciando amostra de LCR levemente hemorrágico. A análise do LCR mostrou presença de 1600 hemácias íntegras sem aumento de leucócitos nem alterações bioquímicas. Houve piora acentuada da cefaléia e após 6 horas apresentou sonolência, torpor e sinais de descerebração. Nova tomografia mostrou sangue no espaço subaracnóideo e nos ventrículos. Uma angiografia realizada de emergência demonstrou laceração da artéria cerebelar póstero-inferior esquerda com a formação de um pseudoaneurisma. O paciente foi de imediato operado tendo sido realizada a clipagem do pseudoaneurisma com sucesso. Dezesseis dias após o paciente teve alta com exame neurológico normal.

Outcome of corneal scleral laceration in Yazd

The aim of this study is to define the epidemiologic characteristics and clinical profile and evaluation of final visual outcome of corneal scleral laceration. A prospective survey was conducted over a two year period from March 2000 to March 2002 on 79 consecutively admitted patients who underwent corneal scleral repairment at Yazd Eye Hospitals. This study included 79 eye injuries. Fifty nine of cases [74.7%] occurred in males and 20 cases [25.3%] in females. Mean age was 17.08 years. Left eye was more commonly involved [57%]. Initial VA was an important predictor of final VA. Good initial VA > 20/200 leading to excellent final VA. 40.6% of traumas occurred in the first decade of life. Injuries less than 10 mm and related to zone I and II predicted a good visual outcome. In this study endophthalmitis [5.1%] was much less likely to develop in eyes with primary repairment within 24 hours from the injury [1.5%] than in eyes being repaired after 24 hours [21.4%] and the difference was significant [P==0.016]. Significant predictive factors for final VA after corneal scleral injury include: initial VA, wound length, wound and location,, and the time of primary repair
