A clinical study of mechanical ventilation in the treatment of acute respiratory failure following abdominal surgery / 中国普通外科杂志

ABSTRACT

Objective To explore the predisposing factors in the development of acute respiratory failure after abdominal surgery and the factors affecting the therapeutic effect of mechanical ventilation. Methods A (retrospective) study was undertaken for acute respiratory failure after abdominal surgery in 91 patients. The (underline) diseases, introducing causes and efficacy of mechanical ventilation were retrospectively analysed. (Results) Postoperative pneumonia was the cause of acute respiratory failure in 53 cases and ARDS caused by severe abdominal infection and severe acute pancreatitis in 38 cases. Of the 91 cases, complicated with COPD in 38 cases, severe malnutrion 32 cases, and hypokalemia 14 cases. Respiratory failure occurred at(4.08?2.45)days after operation. The duration of mechanical ventilation was(21.66?21.42)days; 33 cases died, and 58 cases were successfully recovered with mechanical ventilation.Conclusions The (management) of acute respiratory failure after abdominal asurgery should be rational use of mechanical (ventilation), adjustment of weaning strategy and avoidance of dependance on mechanical ventilation. Timely treatment of the primary disease, effective control of abdominal infection and aggressive symptomatic and (supportive) treatment are factors that affect the success or failure of mechanical ventilation.
