Application of compound lidocaine cream in indwelling urethral catheter after buried penis surgery in children

ObjectiveTo observe the application effect of compound lidocaine cream in indwelling urethral catheter after buried penis surgery in children.

MethodsSixty children with buried penis surgery were divided into the observation group and control group by random number table method, 30 cases in each group.The observation group used compound lidocaine cream to lubricate the catheter, and the control group used liquid paraffin oil to lubricate the catheter.The mean arterial pressure (MAP) and heart rate (HR) were recorded at the time point of before anesthesia induction (T₀), after catheterization (T₁), after laryngeal mask removal (T₂), after being transferred into recovery room (T₃) and after directional force recovery (T₄) in the two groups.The operation time, anesthesia time and stay time in recovery room were recorded.Ramsay sedation score and catheterization-induced agitation score at T₄, one-time success rate of catheterization and urine routine on the first day after operation were compared between the two groups.

ResultsThe one-time success rate of catheterization in the observation group and control group was 90.00% and 93.33%, respectively, and the difference of which was not statistically significant (P>0.05).The stay time in observation group was shorter than that in control group (P < 0.05).MAP and HR in the two groups changed with time, and the difference of which was statistically significant (P < 0.01).At T₄, MAP and HR in observation group were significantly lower than those in control group (P < 0.01).Ramsay sedation score in observation group was significantly higher than that in control group(P < 0.01), and catheterization-induced agitation score was significantly lower than that in control group (P < 0.01).There was no significant difference in the incidence of agitation between the two groups (P>0.05).There was no significant difference in white blood cell, red blood cell and bacterial count between the two groups (P>0.05).

ConclusionsCompound lidocaine cream as a lubricant for indwelling urethral catheter after buried penis surgery in children can reduce agitation caused by catheter stimulation and stress reaction.
