Objectives: To find out the incidence of pulmonary complications post-operatively among elderly patients after elective open upper abdominal surgery under general anaesthesia and to study the effect of preexisting respiratory ailments on post-operative pulmonary complications. Methodology: This was a hospital based cross-sectional study conducted in the department of anaesthesiology, GMC Srinagar. Results: Postoperatively, 49% of the patients had SPO2 less than 94% while on auscultation, there was decreased air entry in about 42% of the patients. On chest X-Ray, the major finding was collapse in 15% of the patients postoperatively. The respiratory rate was increased in 28% of the patients. In total, about 55% of the patients had post-operative pulmonary complications. The presence of preoperative pulmonary complications was associated with the development of respiratory complications in the post-operative period (p<0.001). Conclusion: The presence of preoperative respiratory symptoms was the most important risk factor for the development of postoperative pulmonary complications.
