Abstract

Objective: To compare effectiveness of Laryngeal mask airway versus endotracheal tube to evaluate post-operative sore throat and hoarseness of voice among anesthetized adults.

Study Design: Prospective comparative study

Place and Duration of Study: Operation Theatre Complex, Surgical Ward 1 and 2, Combined Military Hospital, Lahore Pakistan, from Jun to Oct 2020.

Methodology: A total of 70 patients of both gender undergoing elective surgeries were included. Afterwards a lottery method was applied to segregate patients randomly into Group-L and Group-T. In Group-L, airway was secured with laryngeal mask airway while in Group-T, airway was secured with endotracheal tube. Hoarseness of voice was evaluated at time of extubation and 24 hours post extubation.

Results: Demographic data was comparable in both groups. Mean time of anesthesia was 71.31±22.87 and 82.86±32.34 minutes for Group-L and Group-T respectively with p-value of 0.09. Sore throat was seen in 12(34.29%) patients in Group-L as compared to 19(51.43%) in Group-T (p-value=0.094). Hoarseness of voice was seen in 3(8.57%) patients in Group-L as compare to 13(37.14%) in Group-T (p-value= 0.005).

Conclusion: There was less occurrence of postoperative sore throat and hoarseness of voice in patients undergoing elective surgery with laryngeal mask airway as compared with endotracheal tube.
