A standardized questionnaire was used to document patients\u2019 demographics, the presence of comorbidity and type, surgical diagnosis, anesthetic technique, intraoperative adverse events, and outcome of anesthesia. The questionnaire was administered pre- and post-operatively to determine the effects of the comorbidities on the outcome of anesthesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>One hundred and sixty-five adult patients aged between 18 and 84 years were studied. There were 89 (53.9%) females and 76 (46.1%) males. Forty-five (27.3%) have at least one comorbidity. Hypertension was the most common (48.8%) associated illness. Other comorbidities identified include anemia (17.8%), asthma (8.9%), diabetes mellitus (6.7%), chronic renal disease (6.7%), and others. The perioperative period was uneventful in majority of patients (80.6%) despite the presence of comorbidities. Intraoperative adverse events include hypotension, hypertension, shivering, and vomiting. No mortality was reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Hypertension was the most common comorbidity in this cohort of patients.
