Abstract

Evidence based data in the very recent years suggest that in spite of tremendous advances in contemporary anaesthetic practice, advances, airway management continue to be of paramount importance to anesthesiologists. In this RCT (Randomized Control Clinical Trial), the ultimate aim was to depict the anaesthetic safely of the patients of routine laparoscopic cholecystectomy (ASA II & III) in terms of haemodynamic and laryngeal adverse outcomes in BIRDEM General Hospital, Bangladesh. A total number of 200 patients (100 patients with endotracheal tube & 100 patients with LMA) were selected on the basis of simple random sampling. In each patient, after preoxygenation, anaesthesia was introduced with propofol, fentanyl and vecuronium. Anaesthesia was maintained with N2O, O2, Halothane and vecuronium. Ventrilation was set at 8 ml/kg and respiratory rate was 12/min. The ultimate result of this study suggest that in Group A (ETT group), mean±SD of age was 41±1.1 and in Group B (LMA group), it was 37±1.7. Demographic status suggests that the average BMI in both groups were 28.9 and 30.6 respectively. In ETT group, majority of patients (69%) had ASA grade II, in contrast, in LMA group, it was 52%. Average anaesthetic duration in both group were 45 & 50 minutes respectively. There found no significant difference in haemodynamic parameter between both groups at different phases of peroperative period. Laryngeal complications, like tube leakage and gastric insufflation were found in 2 & 3 patients respectively with the use of LMA. Regarding laryngeal morbidity following tube removal, coughing and trauma to lip, teeth, and tongue were slightly higher in with ETT than LMA tube. The incidence of sore throat was slightly higher with the use of LMA (07%) in contrast to ETT (05%), but complications like dysphagia, dysphonia, and dysarthia were found to be same in both groups. P-values suggest less significant result here.
