Abstract

The study aimed to identify the risk factors for respiratory failure after surgery. Postoperative respiratory failure (PRF) was defined as prolonged intubation after surgery or reintubation after unsuccessful extubation. We conducted a retrospective analysis of the following risk factors: age, obesity as reflected by body mass index (BMI), gender, patient admitted to hospital (in-patient status) vs. outpatient surgery, smoking, hypertension, chronic obstructive pulmonary disease (COPD), diabetes, abnormal liver function, anaemia, respiratory infection, physical condition as reflected by ASA class, case type (elective or emergency), anaesthesia type, and surgical duration. The incidence of PRF was found to be 2.4%. Independent risk factors were older age, inpatient status, hypertension, COPD, elective procedure, surgical duration >2 hours, and ASA class ≥3. The study concludes that PRF results in significant postoperative complications. Minimising these risks is essential in improving PRF and subsequently surgical outcomes.

Keywords: Postoperative respiratory failure; Prolonged intubation; Reintubation; Risk factors.
