Effects of dyclonine gel on success rate and complication of laryngeal mask airway insertion / 实用医学杂志

ABSTRACT

Objective To evaluate the effects of dyclonine gel on the success rate and complication of laryngeal mask airway(LMA)insertion. Methods Eighty ASAⅠ~Ⅱpatients undergoing ureteroscopic lithotripsy under general anesthesia received insertion of LMA coated with either dyclonine gel(group A,n=40)or paraffin oil(group B ,n = 40). Systolic blood pressure(SBP),diastolic blood pressure(DBP)and heart rate(HR)were recorded before anesthesia (T0),after induction (T1),at LMA insertion (T2),and 3 min after LMA insertion (T3). Time and frequency of LMA insertion ,incidence of abnormal sensation of pharynx and sore throat after surgery in 2 groups were recorded. Results Compared with those at T0,the SBP,DBP and HR were lower at T1, T2 and T3 in 2 groups(P<0.05). The one-time success rate of group A and group B were 90%and 97.5%respec-tively(P>0.05).The incidence of abnormal sensation of pharynx and sore throat was significantly lower in group A (5%vs. 20%)(P<0.05). Conclusion Dyclonine gel cream-coated LMA can reduce the incidence of sore throat in patients undergoing ureteroscopic lithotripsy under general anesthesia.
