Comparison of application of SLIPA laryngeal mask airway and general anesthesia with endotracheal intubation in pediatric operations

Objective To compare the effects of SLIPA laryngeal mask airway and endotracheal intubation anesthesia on hemodynamics in children and the complications after extubation or removal of laryngeal mask airway.Methods 50 children undergoing lower abdominal and lower limb operations were selected and divided into SLIPA laryngeal mask group(group S)and endotracheal intubation group(group E),with 25 cases in each group.The blood pressure(SBP and DBP)and heart rate(HR)were recorded respectively before anesthesia(T0),before intubation or inserting laryngeal mask airway(T1),after intubation or inserting laryngeal mask(T2),before extubation or removal of laryngeal mask airway(T3),1min after extubation or removal of laryngeal mask airway(T4),and 5min after extubation or removal of laryngeal mask airway(T5).The complications such as cough,laryngeal spasm or bronchial spasm,vomiting,hoarseness,sore throat while extubation or removal of laryngeal mask airway were also recorded.Results Compared with T0,SBP,DBP and HR in two groups were decreased at T1(P0.05).Compared with T1,SBP,DBP and HR in group E were significantly increased at T2 and T4(P0.05),which were also significantly higher than those in group S at T2 and T4(P0.05).After extubation or removal of laryngeal mask airway,the incidences of cough,hoarseness,and sore throat were significantly lower in group S than those in group E(P0.05).Conclusion SLIPA laryngeal mask ventilation can provide less stress reaction and complications of pharynx in pediatric abdomen and limbs operations.
