Abstract

Background: Regarding the highly usage of laryngeal mask for ventilation in GENERAL ANESTHESIA, its easy manipulation and lesser complications comparing with facial masks, and also the importance of exhaled CO2, this study has been carried out in Mofid hospital in 1998 to compare the efficacy of laryngeal and facial mask on exhaled CO2. Materials and methods: This clinical trial of cross over type has performed on 30 patients between 1-12 years old undertaking GENERAL ANESTHESIA for a minor surgery less than one hour. Pre anesthetic drugs were similar an all candidates. Patients were randomly distributed in two groups: In the first group 15 patients were given laryngeal mask and after 15 minutes the respiratory rate and exhaled CO2 were measured, then for 5 minutes the facial mask was replaced and the same indices were measured. In the second group the other 15 patients were given facial mask and after 15 minutes the above indices were measured, then again for another 5 minutes the facial mask was remained and finally the respiratory rate and exhaled CO2 were measured. T-test was used for analyzing these two parameters. Results: Among 30 patients, 10 were girls and the remaining 20 were boys aged 2±6 years old who had undertaken operations including herniorraphy, undescended testis, and orchiopexy. Exhaled CO2 was measured 37±5.2 and 44.3±6.2 mmHg in the facial and laryngeal mask, respectively. Meanwhile, respiratory rate was reported 30.6±8.2 and 31.5±7.9 per minute in the facial and laryngeal mask, respectively. Conclusion: Using laryngeal mask despite its easy manipulation and relatively few complications may lead to higher exhaled CO2 which in turn could cause problems.
