Retrospective Analysis of the Patients Undergoing Neuroanaesthesia between the Years 2015-2019

Abstract

This study aimed to retrospectively evaluate the patients who underwent neuroanesthesia at Ondokuz Mayıs University Faculty of Medicine Hospital between 2015 and 2019. We included all patients who underwent neuroanesthesia between 01.01.2015 and 31.12.2019 and recorded demographic characteristics, comorbidities, type of surgery performed, anesthesia management and complications. We included a total of 5172 patients in the study. 52.9% of the patients were male and the mean age was 43.2%. We observed that the patients were operated most frequently for herniopathy (21.3%), shunt/external ventricular drainage (19.7%) and cranial mass (18.7%), and 77.3% of the cases were elective surgery. The average duration of anesthesia was 145.9 minutes. Thiopental (46.7%) and propofol (45.6%) were used most frequently as induction agents, while rocuronium (93.7%) was preferred as the neuromuscular blocking agent in almost all patients. Remifentanil (81.4%) was the most commonly used intraoperative analgesic. While inhalation anesthesia was preferred for maintenance in 3077 (59.5%) patients, total intravenous anesthesia was used in 1811 (35.1%) patients. Complications developed in 24.1% of the patients, and cardiovascular complications were observed in 71.9%. The study evinced that 1282 patients (24.8%) needed postoperative intensive care. This study revealed that the repetition of retrospective studies at regular intervals would contribute to the development of anesthesiology by enabling both the evaluation of the practices in the same clinic and the comparison between clinics. © 2022 Ondokuz Mayis Universitesi.
