Abstract:
Objective To investigate the application value of local anesthesia with lidocaine carbonate and tetracaine in the prevention of tracheal intubation and extubation response in nasal endoscopy. Methods From January 2016 to March 2017, 90 patients scheduled for endoscopic sinus surgery were randomly divided into 3 groups,with 30 cases in each group.Before endotracheal intubation,1%tetracaine was used for endotracheal surface anesthesia,and air was filled into tracheal intubation airbag(group T). The intratracheal surface was sprayed with physiological saline and 1.73%lidocaine carbonate was filled into tracheal intubation airbag (group C).The 1%tetracaine was used for endotracheal surface anesthesia,and 1.73%lidocaine carbonate was filled into tracheal intubation airbag(group TC).The mean artery pressure(MAP)and heart race(HR)were recorded before induction(T1), immediately after intubation(T2),immediately after extubation(T3),and 5 min after extubation(T4).The scoring of cough during extubation was recorded.Sore throat scores were recorded by using Visual Analogue Scale(VAS)at 30 min,1 h,2 h,6 h and 24 h after extubation,respectively. Results The MAP and HR were less in the group T and TC than those in the group C at T 2(F=8.384,P=0.000;F=6.154,P=0.003), less in the group C and TC than in the group T at T 3(F=14.112, P=0.000; F=3.514,P=0.034).The cough scores were the lowest in the group TC(0.9 ±0.7), median in the group C(1.3 ±0.7), and the highest in the group T(1.7 ±0.5)(F=10.307, P=0.000).The VAS scores of pharyngalgia were the lowest in the group TC (2.1 ±0.8),median in the group C(3.0 ±1.2),and the highest in the group T(3.8 ±1.3)(F=17.961,P=0.000)at 30 min after surgery,and lower in the group TC(1.8 ±0.7)than in the group T(2.5 ±1.0)(F=5.058,P=0.008)at 1 h after surgery.Conclusion Local anesthesia combined with lidocaine carbonate and tetracaine can effectively reduce the cardiovascular response of endotracheal intubation and extubation and relieve the incidence of postoperative cough and sore throat.
