Comparison of application effects of extubation under different anesthesia depth indexes in children undergoing low-temperature plasma radiofrequency ablation of tonsils
Objective:To compare application effects of extubation under different anesthesia depth indexes(NT value)in children undergoing low-temperature plasma radiofrequency ablation of tonsils.Methods:A prospective study was conducted on 76 children who underwent low-temperature plasma radiofrequency ablation of tonsils in this hospital from July 2021 to April 2022.According to the random number table method,they were divided into control group and observation group,38 cases in each group.Both groups underwent tracheal intubation general anesthesia.The control group was extubated at the NT value of 95-100,while the observation group was extubated at the NT value of 80-94.The levels of hemodynamic indexes(heart rate,mean arterial pressure and respiratory rate)at different time[immediately after stopping anesthesia maintenance(T0),immediately after extubation(T1)and 10 min after extubation(T2)],the levels of stress indicators[cortisol(Cor),epinephrine(E)]at different time(before extubation and 30 min after extubation),the local cerebral oxygen saturation(rSO2)at different time(T0,T1,T2),and the incidence of adverse reactions were compared between the two groups.Results:At T1 and T2,the levels of mean arterial pressure,heart rate and respiratory rate of the two groups were higher than those at T0,but those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).30 min after extubation,the levels of Cor and E in the two groups were higher than those before extubation,but those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).At T0,T1 and T2,there were no significant differences in the rSO2 level between the two groups(P>0.05).The incidence of adverse reactions in the observation group was 5.26%(2/38),which was lower than 21.05%(8/38)in the control group,and the difference was statistically significant(P<0.05).Conclusions:Extubation under NT value of 80-94 in the children with low-temperature plasma radiofrequency ablation of tonsils can improve the levels of hemodynamic indexes and stress indicators and reduce the incidence of adverse reactions.Moreover,it is superior to extubation at NT value of 80-94.
