Abstract:
Objective To investigate the effectiveness and safety of applying compound lidocaine cream on tracheal mucosa as topical anesthesia to reduce the stress reaction during extubation of tracheal tube. Methods Sixty patients (aged 18-65yr,body weight 40-80kg,ASA Ⅰ-Ⅱ) scheduled for elective surgery under general anesthesia were selected,and they were randomly divided into compound lidocaine cream group (group L,n=30) and control group (group C,n=30). Orotracheal intubation was performed in all the patients. Compound lidocaine cream was uniformly smeared on the foremost third of endotracheal tubes before intubation in group L,and no drug was coated on endotracheal tubes in group C. The changes in blood pressure and heart rates during extubation,the use of hypotensive drugs,cough reflex,breath holding,sore throat and pharyngeal discomfort after extubation were compared between the two groups. Results The operation and intubation time of the two groups showed no significant difference. The blood pressure and heart rate during extubation,the rate of using hypotensive drugs,and the incidence of cough reflex and breath holding were lower in group L than in group C,while the foreign body sensation in pharynx were after extubation was more frequent in group L than in group C. The incidence of pharyngodynia was similar in the two groups,and the pharyngodynia and foreign body sensation in pharynx markedly improved one day after operation in both groups. Conclusion Topical anesthesia of tracheal mucosa using compound lidocaine cream may reduce the cough reflex and breath holding during extubation,and inhibit the stress reaction.
