The Retrospective Analysis of the Patients Who Underwent Direct Laryngoscopy in Terms of Anesthesia Between 2000 and 2010

Abstract

Objective: In our study we aimed to retrospectively analyze a total of 2.233 patients who underwent direct laryngoscopy (DL) between 2000 and 2010 at Ondokuz Mayis University, Department of Anesthesiology. Method: The data were obtained by analyzing preoperative-intraoperative anesthesia registration forms and hospital computerized-automation system. Results: According to the results, the number of patients underwent DL increased over the years, the indication in 57% of the patients was benign and malignant diseases of the larynx, 88% of the patients were male, 54% were aged between 45 and 65, 15% had an ASA score of 3-4, 98% were underwent elective surgery and 64,5% had one or more additional systemic disease. 6,3% of the patients (140 patients) were identified as having a difficult intubation. Mallampati score (MS) could be obtained for only 1542 patients (69,1). Accordingly, 1482 patients (%96) had a Mallampati score of 1-2 and 60 patients (%4) had a Mallampati score of 3-4. The most commonly used agents in anesthesia were propofol (93%) for induction, succinylcholine (48%) and mivacurium (39%) as muscle relaxants, sevoflurane (%56) and nitrous oxide (68%) in maintenance. In recent years, the use of propofol, rocuronium, and remifentanil was increased. Conclusion: We suggest that several studies can be done from anesthesia records maintained regularly and systematically, and doing these studies at certain intervals may contribute to continuous assessment of the clinical interventions and to the development of anesthesiology, enabling comparisons to be made between clinics.
