The purpose of in pediatric short surgical anesthesia, two airway protection device laryngeal mask endotracheal tube compared to the application and promotion in the region provide the basis for evaluation of laryngeal mask usage in short anesthesia for pediatric laryngeal mask. Methods minor surgery in August 2010 to December 2010, the First Affiliated Hospital of Guangxi Medical University (expected operation time ≤ 2 hours), 65 cases in August -13 years were randomly divided into laryngeal mask (LMA group, n = 32) and intubation group (ETT group, n = 33). Both groups using propofol 3mg/kg fentanyl 3μg/kg induction of anesthesia, the the ETT group added vecuronium 0.1mg/kg the LMA group choose the laryngeal mask the ETT group into the endotracheal tube . Based on end-tidal carbon dioxide concentration was adjusted respiratory parameters, so that it does not exceed 40mmHg. Both groups were given sevoflurane 2% to 3% to maintain anesthesia inhalation combined with propofol 10mg/kg intravenous pump into. To record patients preoperative, intraoperative and postoperative situations, including preoperative gender, age, weight, ASA physical status, the number of operations of the LMA inflated, placed before the laryngeal mask (T1), placed in the laryngeal mask after (T2), surgery start time (T3) after the start of surgery, 15 min (T4), the end of surgery (T5), (T6) pulled out of the heart rate (HR), systolic blood pressure (SBP), pulse oxygen saturation (SpO2), end-tidal carbon dioxide partial pressure (PETCO2), recorded surgical start and end time, unplug the airway device out of room time, intraoperative and postoperative adverse reactions. Results (1) the patients gender composition, age, ASA classification compare the difference was not statistically significant (P gt; 0.05). (2) two cases of children placed LMA failed to change endotracheal intubation, the results are not included in the LMA group. (3) patients in the two groups SpO2 was no significant difference (P gt; 0.05), there was no hypoxemia (SpO2 <94%), carbon dioxide waveform smooth, PETCO2 did not exceed 40mmHg. LMA group and ETT group placed airway protection device, the LMA group of intraoperative peak airway pressure than ETT group, a statistically significant (P lt; 0.05). Intraoperative use of the LMA compared with ETT HR and SBP, P lt; 0.05. (4) after surgery in children unplug the the airway device time and recovery room stay time LMA group than short ETT group, P lt; 0.05. Overall complication rate of LMA group compared with the ETT group (P lt; 0.05), after extubation occurred choking LMA group compared with the ETT group (P lt; 0.05), postoperative nausea and vomiting and bloating rate between the two groups was no difference (P gt; 0.05). Conclusion pediatric laryngeal mask minor surgery is safe and feasible, and master the appropriate depth of anesthesia laryngeal mask can be used as alternatives to promote the application of endotracheal intubation.
