Maximum inspiratory and expiratory pressures in the pre and postoperative periods of patients with incisional abdominal hernia corrected by Lázaro da Silva technique.

OBJECTIVE: To verify the effect of longitudinal abdominal incisional herniorrhaphy on respiratory muscle pressure. METHOD: The technique of incisional herniorrhaphy used was proposed by Lázaro da Silva. To measure the pressure, we used a water manometer in 20 patients, median age 48.5 years (range 24 70). We analyzed the maximum inspiratory pressure at the level of residual volume (IP-RV) and functional residual capacity (IP-FRC) and the maximum expiratory pressure of functional residual capacity (EP-FRC) and total lung capacity (EP-TLC) in the preoperative and late postoperative (40 90 days) periods, in 13 patients with large incisional hernias and in 7 patients with medium incisional hernias. RESULTS: There was a significant increase in IP-FRC (p = 0.027), IP-RV (p = 0.011) and EP-TLC (p = 0.003) in patients with large incisional hernias. EP-FRC increased, but not significantly. In patients with medium incisional hernias, the changes were not significant. CONCLUSION: Surgical correction of large incisional hernias improves the function of the breathing muscles; however, surgery for medium incisional hernias does not alter this function.

Purple urine bag syndrome: case report.

A 65-year-old male with a history of urinary tract trauma requiring cystotomy and chronic bladder catheterization, presenting with chronic and uninvestigated changes in the color of the urine bag system, with no urine color change, and positive urine culture for Proteus mirabilis . These characteristics refer to the purple urine bag syndrome, a not weel-known condition, with a benign course in most cases, and associated with urinary tract infection in patients with chronic bladder catheterization. Although it is characterized by marked changes, it is underdiagnosed by healthcare professionals.

RESUMO Homem de 65 anos com história de trauma do sistema urinário, sendo necessário cistotomia e sondagem vesical crônica, apresentando alterações crônicas e não investigadas da cor do sistema coletor de urina, sem alteração da cor da urina, e urocultura positiva para Proteus mirabilis . Tais características remetem à síndrome do saco coletor de urina roxo, uma entidade pouco conhecida, de curso benigno na maioria da vezes, associada à infecção urinária em paciente com cateterismo vesical de demora. Embora seja caracterizada por alterações marcantes, é subdiagnosticada pelos profissionais de saúde.

Maximum inspiratory and expiratory pressures in the pre and postoperative periods of patients with incisional abdominal hernia corrected by Lázaro da Silva technique / Pressões máximas inspiratórias e expiratórias no pré e pós-operatório de pacientes com hérnias incisionais abdominais corrigidas pela técnica de Lázaro da Silva

RESUMO Objetivo: verificar o efeito da herniorrafia incisional abdominal longitudinal na pressão dos músculos da respiração. Método: a técnica de herniorrafia incisional utilizada foi a proposta por Lázaro da Silva. Para aferir a pressão foi utilizado manômetro de água, em 20 pacientes, idade mediana 48,5 anos (mínimo 24, máximo 70). Foram analisadas a pressão máxima inspiratória no nível do volume residual (PIVR) e da capacidade residual funcional (PICRF) e a pressão máxima expiratória da capacidade residual funcional (PECRF) e da capacidade pulmonar total (PECPT), no pré-operatório e pós-operatório tardio (entre 40 e 90 dias), em 13 pacientes com hérnias incisionais grandes e em 7 pacientes com hérnias incisionais médias. Resultados: houve aumento significante da PICRF (p=0.027), da PIVR (p=0.011), da PECPT (p=0.003) nos pacientes com hérnias incisionais grandes. A PECRF aumentou, porém de forma não significante. Nos pacientes com hérnias incisionais médias as alterações não foram significantes. Conclusão: a correção cirúrgica da hérnia incisional grande melhora a função dos músculos da respiração, porém a cirurgia da hérnia incisional média não altera a referida função.
