ABSTRACT

Introduction: The laryngeal mask, in circumstances and patients selected, is an aerial route with a minimal access more safe than the endotracheal tube.
Objective: To assess the use of the classic laryngeal mask in emergency surgery.
Methods: Eighty patients of both sexes were seen and classified according the ASA (American Society of Anesthesiologists) physical status as I and II aged between 18 and 60, distributed at random two groups with 40 patients each. Patients received balanced general anesthesia using midazolam, isoflurane and atracurio. Airway was approached with: laryngeal mask (group I) and endotracheal tube (Group II). The following variants were assessed: age, sex, ASA, surgical time, anesthetic time, laryngeal mask, blood pressure, heart rate, oxygen peripheral saturation.
Results: Regarding the previous ASA criteria there was predominance of type I (52,3%). The more used laryngeal mask used was the No. 4 for a 42,2%. As regards the mean surgical and anesthetic times, these were of 35 and 47 min, respectively. The mean systolic blood pressure before aesthesia was of 125,2 ± 17,8 mmHg and at the end of anesthesia it was of 109,2 ± 10,8 mmHg.
Conclusions: There were not significant differences between both groups compared as regards age, sex, ASA, surgical and anesthetic time and basal hemodynamic parameters. After insertion and extraction of devices there were significant differences noting a great hemodynamic stability using the laryngeal mask. The airway approach with the classic laryngeal mask in patients under general anesthesia produce less hemodynamic changes than when the endotracheal intubation is used.
