Comparison of postoperative sore throat following laryngoscopy conducted by Miller and Macintosh laryngoscope blades
ABSTRACT
BACKGROUND: Post operative sore throat (PST) is one of the most common complaints after tracheal intubation. In this study we compared the effects of curved and straight laryngoscope blades on severity and incidence of PST. METHOD: In this prospective randomized clinical trial we evaluated incidence and severity of PST in 147 ASA physical status I–II, aged 18 – 62 y (group Miller, n = 71), (group Macintosh, n = 76) following intubation with Miller and Macintosh laryngoscope blades by using Visual Analog Scale (VAS). RESULTS: The overall incidence of PST in our study was 35.4% (Macintosh group = 39.5% and in Miller group = 31% and P = 0.829). The incidence of PST was not statistically different between two kinds of laryngoscope blades and the mean rank of pain score was not statistically different in recovery room and up to 48 hours after surgery. CONCLUSIONS: Our study showed these types of laryngoscope blade had not association with incidence and severity of PST. .
