Abstract

Abstract Background and objective: To observe the prevalence of atelectasis in patients undergoing bariatric surgery and the influence of the body mass index (BMI), gender and age on the prevalence of atelectasis. Method: Retrospective study of 407 patients and reports on chest X-rays carried out before and after bariatric surgery over a period of 14 months. Only patients who underwent bariatric surgery by laparotomy were included. Results: There was an overall prevalence of 37.84% of atelectasis, with the highest prevalence in the lung bases and with greater prevalence in women (RR = 1.48). There was a ratio of 30% for the influence of age for individuals under the age of 36, and of 45% for those older than 36 (RR = 0.68). There was no significant influence of BMI on the prevalence of atelectasis. Conclusion: The prevalence of atelectasis in bariatric surgery is 37% and the main risk factors are being female and aged over 36 years.

Resumo

Resumo Justificativa e objetivo: Observar a prevalência de atelectasia em pacientes submetidos à cirurgia bariátrica e a influência do índice de massa corporal (IMC), do sexo e da idade sobre a prevalência de atelectasia. Método: Estudo retrospectivo de 407 pacientes e laudos de radiografias de tórax feitas antes e após a cirurgia bariátrica durante 14 meses. Apenas os pacientes submetidos à cirurgia bariátrica por laparotomia foram incluídos. Resultados: Houve uma prevalência geral de atelectasia de 37,84%, com maior prevalência nas bases pulmonares e em mulheres (RR = 1,48). Houve uma proporção de 30% para a influência da idade nos indivíduos com menos de 36 anos e de 45% naqueles com mais de 36 anos (RR = 0,68). Não houve influência significativa do IMC sobre a prevalência de atelectasia. Conclusão: A prevalência de atelectasia em cirurgia bariátrica é de 37% e os principais fatores de risco são sexo feminino e idade superior a 36 anos.
