ObjectiveTo investigate the clinical effect of laryngeal mask anesthesia in short-time pediatric surgery. MethodsA total of 60 cases of children planed to receive short-time surgery were randomly divided into study group and control group,30 cases in each group. According to the weight of children, the type of the third generation laryngeal mask were selected in the study group, then the children were given intravenous injection of atropine 0.01 mg/kg, sufentanil 0.25 g/kg and propofol 2 mg/kg respectively；After the disappearance of the throat reflex, jaw relaxation, eyelash reflex disappeared, laryngeal mask were installed. The children of control group were given intramuscular injection of ketamine (4-5 mg/kg) or intravenous injection of ketamine (1-2 mg/kg). The blood pressure, heart rate, respiratory rate, oxyhemoglobin saturation and anesthesia effect of the two groups were observed and compared during the operation. ResultsThe heart rate and respiratory rate of 5 min and 15min in the study group were significantly lower than those in the control group, the difference was statistically significant (P＜0.05).Compared with the control group, the 5 min and 15 min oxyhemoglobin saturation of the study group was not statistically significant (P＞0.05).The highest blood pressure of 5 min and 15 min in the study group were significantly lower than those in the control group, the difference was statistically significant (P＜0.05) . The analepsia time of the study group was (10.3±5.7) min,significantly shorter than (17.5±7.6) min of the control group, the difference was statistically significant (P＜0.05). The incidence of adverse reactions in the study group was significantly lower than that in the control group, the difference was statistically significant (P＜0.05). ConclusionLaryngeal mask anesthesia has the characteristics of lower heart rate and respiratory rate, smooth anesthesia, high oxyhemoglobin saturation, short analepsia time, less adverse reactions, which can be used in clinical application.
