Resumo

JUSTIFICATIVA E OBJETIVOS: A medicina endoscópica está cada vez mais sendo usada atualmente, porém não é isenta de riscos. Portanto, este estudo avaliou os fatores associados com complicações perioperatórias em cirurgias endoscópicas com irrigação intraoperatória. MÉTODO: Estudo de coorte durante seis meses. Foram incluídos pacientes com > 18 anos, submetidos a cirurgias endoscópicas que usariam fluidos de irrigação no intraoperatório. Pacientes em uso de diuréticos, com insuficiência renal, distúrbios cognitivos, hiponatremia prévia a cirurgia, gestantes e moribundos foram excluídos. Foram alocados em dois grupos os pacientes que apresentaram complicações ou não no período perioperatório. As complicações avaliadas estavam relacionadas a alterações neurológicas, cardiovasculares, renais e sangramentos no perioperatório. RESULTADOS: Foram incluídos 181 pacientes e 39 excluídos, portanto 142 preencheram os critérios. Apresentaram complicações 21,8% dos pacientes, com maior ocorrência em cirurgias endoscópicas de próstata, seguidas de histeroscopias, bexiga, artroscopia de joelho e ombro, respectivamente 58,1%, 36,9%, 19,4%, 3,8% e 3,2%. Comparando os grupos, apresentaram associação com complicações na análise univariada; idade, sexo, tabagismo, cardiopatia, ASA, sódio sérico no fim da cirurgia, total de fluido de irrigação administrado, ressecção transuretral de próstata, histeroscopia. Entretanto, apenas idade (OR = 1,048), sódio sérico (OR = 0,962) e volume de fluido de irrigação administrado no intraoperatório (OR = 1,001) foram variáveis independentes para complicações na regressão múltipla. CONCLUSÃO: Graves complicações em cirurgias endoscópicas têm grande ocorrência. O sódio sérico no fim da operação, a quantidade de fluido de irrigação e a idade foram fortes fatores independentes associados ao problema. Dessa forma, tais fatores devem ser levados em consideração nesses tipos de cirurgias.

Abstract

BACKGROUND AND OBJECTIVES: Currently, endoscopic medicine is being increasingly used, albeit not without risks. Therefore, this study evaluated the factors associated with perioperative complications in endoscopic surgery with intraoperative irrigation. METHOD: A cohort study of six months duration. Patients aged > 18 years undergoing endoscopic surgery with the use of irrigation fluids during the intraoperative period were included. Exclusion criteria were: use of diuretics, kidney failure, cognitive impairment, hyponatremia prior to surgery, pregnancy, and critically ill. The patients who presented with or without complications during the perioperative period were allocated into two groups. Complications evaluated were related to neurological, cardiovascular and renal changes, and perioperative bleeding. RESULTS: In total, 181 patients were enrolled and 39 excluded; therefore, 142 patients met the study criteria. Patients with complications amounted to 21.8%, with higher prevalence in endoscopic prostate surgery, followed by hysteroscopy, bladder, knee, and shoulder arthroscopy (58.1%, 36.9%, 19.4%, 3.8%, 3.2% respectively). When comparing both groups, we found association with complications in univariate analysis: age, sex, smoking, heart disease, ASA, serum sodium at the end of surgery, total irrigation fluid administered, TURP, and hysteroscopy. However, in multiple regression analysis for complications, only age (OR = 1.048), serum sodium (OR = 0.962), and volume of irrigation fluid administered during surgery (OR = 1.001) were independent variables. CONCLUSION: The incidence of serious complications in endoscopic surgeries is high. Serum sodium at the end of the operation, amount of irrigation fluid, and age were strong independent factors associated with the problem. Thus, these factors must be taken into account in these surgeries.
