Prognostic factors of intraoperative awakening

Abstract

A prospective longitudinal cohort study was carried out in patients announced for major elective surgery, with orotracheal general anesthesia, at the “Carlos Manuel de Céspedes de Bayamo Provincial Hospital, from the Cauto region during the period from January 1, 2016 until December 31, 2018; with the objective of identifying the risk factors hypothetically related to the prognosis of intraoperative awakening. The exposed cohort consisted of two patients who experienced intraoperative awakening in the study period, and met the inclusion criteria. The magnitude of the associations was estimated by calculating the relative risks (RR). Age equal to or greater than 65 years, difficult intubation, patients with ASA III and IV physical status, and chronic alcohol ingestion, were the surgical risk factors depending on the patient, associated with the prognosis of awakening. Intraoperative in patients announced for major elective surgery, under general orotracheal anesthesia, although not significantly; while the female sex did not present an association. The time of surgery equal to or greater than four hours, was constituted in the surgical risk factor depending on the surgery, related to the prognosis of appearance of intraoperative awakening in patients announced for major elective surgery, with orotracheal general anesthesia.
