Abstract:
Objective To study the effect of tetracaine jelly on hemodynamics during extubation period in general anesthesia.Methods One hundred patients who performed tracheal cannula and general anesthesia were divided into control group (50 patients) and experiment group (50 patients) by random digits table method.Control group:sterile paraffin oil was applied to the endotracheal tube.Experiment group:tetracaine jelly was applied to the endotracheal tube.The systolic blood pressure (SBP),diastolic blood pressure (DBP) and heart rate(HR) were measured before the anesthesia induction(T1),5 min after stopping infusion drugs (T2),1 min after tracheal extubation (T3),3 min after tracheal extubation (T4) and 5 min after tracheal extubation (T5) were observed.The resistant effect after waking and the number of sore throat,hoarseness were recorded.Results The level of SBP,DBP,HR at T1 and T2 had no significant difference between two groups (P ＞ 0.05).The level of SBP,DBP,HR at T3-T5 in experiment group were significantly lower than those in control group [SBP:(122.3 ± 11.3),(120.0 ± 9.8),(112.0 ± 6.3) mmHg (1 mmHg =0.133 kPa) vs.(158.3 ± 15.0),(142.5 ± 13.5),(133.0± 14.5) mmHg;DBP:(75.0 ± 13.5),(75.8 ± 10.5),(58.3 ±4.2) mmHg vs.(111.0 ± 20.3),(106.5 ± 12.8),(63.8 ± 15.8) mmHg;HR:(81.9 ± 13.7),(83.6 ± 13.4),(60.7 ± 3.5) times/min vs.(113.5 ± 19.4),(117.5 ± 21.7),(71.8 ± 14.6) times/min](P ＜ 0.05).The total effective rate of tolerance in experiment group was higher than that in control group [96％(48/50) vs.56％(28/50)],the rate of sore throat and hoarseness were lower than those in control group [6％ (3/50) vs.48％ (24/50),4％ (2/50) vs.36％ (18/50)],there were significant differences (P ＜ 0.05).Conclusion Tetracaine jelly can reduce the cardiovascular response of tracheal extubation,enhance the tolerance of tracheal tube and decrease the morbidity of sore throat and hoarseness.
