Abstract

Acute respiratory failure is a common postoperative complication, especially in obese patients who are prone to ventilation-perfusion mismatch and airway obstruction. This paper examines the results of the short-term non-invasive ventilation (NIV) administered in the first 24 hours of surgery on the obese population. Obese patients (BMI 30-45, ASA II-III) who were undergoing minor peripheral surgery were randomly selected (n=144) and divided into two groups (NIV n=60 and standard care (control) n=60). Postoperative spirometry and pulse oximetry measurements were taken at multiple intervals to assess respiratory function. Results showed that NIV significantly improved oxygen saturation and lung function in the initial 12 hours compared to the control group. Despite modest overall differences, NIV demonstrated a faster recovery of lung function and reduced risk of atelectasis in the PACU. This study suggests that early NIV can be beneficial in improving postoperative pulmonary outcomes, particularly in obese patients, and may offer a practical therapeutic approach in day surgery settings.
