The effect of the usage of laryngeal mask with different cuff pressures on intraoperative hemodynamy and postoperative morbidity in curettages

Objective: This study was aimed to investigate and compare the effect of the inflation of LMA cuff to pressures of 40 cmH2O and 60 cmH2O on intraoperative hemodynamy and postoperative sore throat, earache, dysphonia, dysphagia, bleeding, nausea, vomitting during curettages that are short-duration operations.Methods: This is a prospective, randomized study. Sixty ASA I-II female patients who would undergo elective curettage under general anesthesia were randomized to two groups. The LMA cuff was inflated to 60 cmH2O in Group I (n=30) patients and 40 cmH2O in Group II (n= 30) patients.Preoperative basal heart rate; systolic, diastolic and mean blood pressures, SpO2 values, intraoperative heart rate, systolic, diastolic and mean blood pressure, SpO2 and end-tidal CO2 values, laryngeal mask cuff pressure (following the LMA application at 1st, 5th, 10th, 15th and 20th minutes) values were all recorded. Also, heart rate, systolic, diastolic and mean blood pressure, SpO2 values at the 20th minute of postoperative period were recorded. Sore throat, earache, dysphonia, dysphagia, bleeding, nausea, vomitting at the 20th minute of preoperative and postoperative periods were recorded.Results: There were no differences between the two groups with respect to demographic characteristics of the patients, duration of operations and LMA trying periods. Also there were no differences between the two groups concerning the intraoperative hemodynamy and postoperative sore throat, earache, dysphonia, dysphagia, bleeding, nausea, vomitting.Conclusion: Inflation of LMA cuff to 40 cmH2O and 60 cmH2O during curettages which are short-duration operations, did not make any differences concerning the intraoperative hemodynamy and postoperative sore throat, earache, dysphonia, dysphagia, bleeding, nausea, vomitting. Cuff pressures were measured continuously. Cuff pressures that we used can be used safely.Key Words: Laryngeal Mask, cuff pressure, postoperative morbidity, intaoperative hemodynamyContact Adress: drsahinali@yahoo.com
