Comparison of Postoperative Pulmonary Complications Between Smokers and Nonsmokers

This is a prospective observational study designed to evaluate the effect of smoking on early postoperative respiratory symptoms such as cough, airway secretions, and wheezing in adult patients undergoing elective abdominal surgery. Participants will be divided into two groups based on smoking history. The study aims to assess the incidence of minor pulmonary complications-such as increased secretions requiring suctioning, oxygen need, and early respiratory discomfort-within the first 24 hours after surgery. Data will be collected on parameters including secretion volume, oxygen saturation, aspiration frequency, and presence of cough or wheezing. The results will help determine whether active smoking is associated with a higher frequency of early postoperative pulmonary events.
