Abstract

Background and objectives: To assess lung ultrasound for the diagnosis and monitoring of respiratory complications in thoracic surgery.

Methods: Prospective observational study in a University hospital, single institution. Adult patients scheduled for pulmonary resection surgery excluding pneumonectomy. An ultrasound follow-up was performed from the day before the surgery to the third day after surgery with calculation of B-line and lung score (reaeration and loss of aeration scores). Respiratory complications were collected throughout the hospitalization period.

Results: Fifty-six patients were included. Eighteen patients presented a respiratory complication (32%), and they presented significantly higher BMI and ASA scores. Patients operated by videothoracoscopy were less at risk of complications. At day 3, a reaeration score = 2 on the ventilated side or =-2 on the operated side, and a B-line score > 6 on the operated side were in favor of a complication.

Conclusion: Lung ultrasound can help in the diagnosis of respiratory complications following pulmonary resection surgery.

Resumo

Justificativa e objetivos: Avaliar a ultrassonografia pulmonar para o diagnóstico e acompanhamento das complicações respiratórias em cirurgia torácica. 

Métodos: Estudo prospectivo observacional em hospital universitário, única instituição. Pacientes adultos programados para cirurgia de ressecção pulmonar, excluindo pneumectomia. O acompanhamento ultrassonográfico foi realizado do dia anterior à cirurgia até o terceiro dia após a cirurgia com cálculo da linha B e escore pulmonar (escores de reaeração e perda de aeração). As complicações respiratórias foram coletadas durante todo o período de internação.

Resultados: Cinquenta e seis pacientes foram incluídos. Dezoito pacientes apresentaram complicação respiratória (32%) e apresentaram IMC e pontuação ASA significativamente maiores. Os pacientes operados por videotoracoscopia apresentaram menor risco de complicações. No dia 3, um escore de reaeração ≤ 2 no lado ventilado ou ≤ -2 no lado operado e um escore de linha B> 6 no lado operado foram a favor de uma complicação.

Conclusão: A ultrassonografia pulmonar pode auxiliar no diagnóstico de complicações respiratórias após cirurgia de ressecção pulmonar.
