A randomized control study comparing the pharyngolaryngeal morbidity of laryngeal mask airway versus endotracheal tube



A randomized control study comparing the pharyngolaryngeal morbidity of laryngeal mask airway versus endotracheal tube



Anesthesia Essays and Researches 10(2): 189-194



Endotracheal tube (ETT) has been associated with various pharyngolaryngeal morbidities (PLMs) following general anesthesia (GA). Laryngeal mask airway (LMA), currently the most commonly used supraglottic airway device, has several advantageous over the ETT but has been associated with varying results of PLM. The aim of our study was to compare the PLM between them and to know whether LMA is a better alternative. One hundred and seventy American Society of Anesthesiologists Grades 1 and 2 women scheduled for elective mastectomy were included in the study, 85 each in either group, E Group (intubated with ETT) and L Group (using LMA) on a random basis. All patients received GA with controlled ventilation using a muscle relaxant. PLMs such as hoarseness, pain on phonation, sore throat, and difficulty in swallowing were documented by an interview done postoperatively. Peroperative parameters such as intubation attempts, trauma during airway device insertion, and intraoperative incidents were also analyzed. A sample size of 85 patients in each group was calculated in order to achieve a study power of 0.8 and alpha level was taken as 0.05. Data were analyzed using SPSS version 16 using Chi-square test, Mann-Whitney U-test and Fisher's exact test were used as nonparametric tests. A two-tailed P< 0.05 was considered significant. Patients in E Group had statistically significant increased incidence of a sore throat and voice complaints whereas L Group showed a statistically significant increase of swallowing problems. There was also a significant correlation between traumatic insertion and sore throat, pain on swallowing in the L Group, which could be due to direct trauma. ETT was associated with an increased incidence of voice problems and sore throat whereas LMA had an increased incidence of dysphagia and odynophagia. Use of LMA changes the pharyngolaryngeal profile to a more acceptable one.
