Prevalence of Obstructive Sleep Apnea in Surgical Patients Attending at Skims Hospital, Kashmir, and its Correlation with Perioperative Morbidity

ABSTRACT

Background and Objective: Patients presenting for surgical procedures often get undiagnosed for obstructive sleep apnea(OSA), thus increasing the incidence of perioperative adverse outcomes. Hence, early diagnosis of this disease is importantin formulating anesthetic management and specific means which may decrease the complications and improve outcome,and therefore, the study was conducted to evaluate the prevalence of OSA in patients presenting in our institute for surgicalprocedures.Materials and Methods: A total of 600 patients of aged >18 years, American Society of Anesthesiologists I-III scheduled forelective surgeries under anesthesia, were randomly enrolled in the study. Their demographic data, anthropometric measurementswere noted. They were screened for OSA by STOP-BANG questionnaire and were followed to assess correlation betweenOSA and perioperative morbidity.Results: We observed that out of a total of 600 patients, 23 patients had moderate and severe OSA. Hence, the prevalence ofmoderate-to-severe OSA was 3.8% in our study. Mean age of subjects was 43.1 years and female predominance was seen inthis study. Out of a total of 600 patients, 23 patients had moderate and severe OSA. There was a significant correlation betweenseverity of OSA and anthropometric measurements and perioperative morbidity.Conclusion: Early screening can help in detecting the OSA among patients and thus help in alleviating perioperative morbidity
