Obstructive Sleep Apnea, Postoperative Complications
Conditions
Keywords
obstructive sleep apnea, postoperative pulmonary complications, general anesthesia
Brief summary
It is known that perioperative respiratory complications occur more often in obstructive sleep apnea syndrome (OSAS) patients during general anesthesia. Although there are prospective RCTs in this area, the need for further and larger studies remains due to the heterogenity of the results. Moreover, the incidence of postoperative pulmonary complications in OSAS patients undergoing surgery in Turkey and the predictive factors affecting the respiratory adverse events are uncertain. Therefore, in this prospective observational cohort study, it was aimed to determine the incidence of postoperative pulmonary complications and the predictor factors associated with patient, anesthesia and surgery in surgical patients with a confirmed or highly suspected OSAS diagnosis undergoing general anesthesia.
Interventions
The incidence of postoperative pulmonary complications in OSAS patients undergoing elective surgery under general anesthesia will be determined.
