不同麻醉方式用于支气管镜诊疗的临床观察OACSTPCD

Objective To observe the adverse reactions of different anesthesia methods used in bronchoscopic diagnosis and treatment,and provide ideas for clinical selection of the best anesthesia methods.Methods 150 patients from June 2022 to June 2023 for bronchoscope were randomly divided into group W(atomization with lidocaine combined with intravenous sedation),group Q(laryngeal mask general anesthesia)and group H(lidocaine sprayed by laryngeal anesthetic tube combined with general anesthesia),with 50 cases in each group.Heart rate(HR),mean arterial pressure(MAP)and percutaneous arterial oxygen saturation(SpO2)values were recorded at different time points,adverse reactions during recovery,recovery time and dosage of anesthetic drugs were recorded.Results At T1 and T2,SpO2 in group W(89.4±0.7)%and(91.8±0.3)%were lower than that(99.6±0.8)%in T0,and lower than those(98.6±1.3)%and(98.5±1.6)%in group Q and(99.7±0.3)%and(98.4±1.6)%in group H,the difference were statistically significant(P<0.05).At T1 and T2,the MAP of group W were(108.5±7.8)and(105.6±7.3)mmHg,which were significantly higher than those of T0(87.5±8.6)mmHg,and higher than those of group Q(92.6±8.5)and(85.8±11.3)mmHg,respectively,higher than those(85.7±9.2)and(85.2±10.8)mmHg in group H,the differences were statistically significant(P<0.05).The MAP of group Q at T1 and T3 was(92.6±8.5)and(91.4±8.6)mmHg,respectively,higher than that of T0(87.8±7.5)mmHg,and higher than those of group H(85.7±9.2)and(86.5±7.2)mmHg,with statistical significance(P<0.05).At T1 and T2,the HR of group W was(92.7±9.6)and(91.3±9.2)times/min,higher than that of T0(72.3±8.4)times/min,and higher than those of group Q(75.3±11.6)and(78.5±12.8)times/min,respectively,and higher than those of group H(76.6±10.7)and(77.2±8.5)times/min,and the differences were statistically significant(P<0.05).The hypoxemia,arrhythmia and cough rates in group Q were higher than those in group W and group H,and the differences were statistically significant(P<0.05).The recovery time of group H was(11.5±7.2)min,which was significantly lower than that of group W(16.8±8.5)min and group Q(17.6±6.4)min,and the differences were statistically significant(P<0.05).The dosage of propofol in group H was(314.3±12.7)mg and remifentanil was(211.6±12.5)μg,both lower than those in group W(390.5±12.4)mg and(268.4±13.6)μg,and lower than those in group Q(387.6±15.2)mg and(372.5±15.3)μg.The differences were statistically significant(P<0.05).The dosage of micuronium chloride was(23.7±3.8)mg in group H,lower than(32.5±4.3)mg in group Q,and the difference was statistically significant(P<0.05).Conclusion Lidocaine sprayed by laryngeal anesthetic tube combined with general anesthesia is the best anesthesia method for bronchoscopic diagnosis and treatment,which is beneficial to respiratory management and less adverse reactions in perioperative period.
