Effect of lidocaine combined with ropivacaine in penile dorsal nerve block for pediatric circumcision

Abstract

Objective To explore the effect of lidocaine combined with ropivacaine in penile dorsal nerve block for pediatric circumcision. Methods 130 children with pediatric circumcision surgery were divided into observation group and control group by the digital meter method, 65 cases in each group.The control group was taken inhaled sevoflurane composite static note ketamine surgery, the observation group was given ropivacaine combined with intravenous infusion of ketamine for penile dorsal nerve block anesthesia.The anesthesia effects of the two groups were recorded. Results In the observation group, 10 min after surgery, the rhythm of the heart was (98.47±10.88)times/min, central arterial pressure was (65.13±7.78)mmHg.In the control group, 10min after surgery, the rhythm of the heart was (121.78±15.23)times/min, central arterial pressure was (85.27±12.31)mmHg, the differences between the two groups were statistically significant(t=10.040, 11.150, all P<0.05). In the observation group, the used ketamine, waking up time, pain score, incidence rate of pain and irritability were (41.38±11.28)mg, (5.54 ±1.03)min, (2.11±1.13)points, 7.69%, respectively, which in the control group were (71.47±16.82)mg, (13.67±2.57)min, (3.89±1.79)points, 26.15%, respectively, the differences between the two groups were statistically significant(t=11.978, 23.673, 6.779, χ2=7.878, all P<0.05). Conclusion The anesthesia effect of lidocaine combined with ropivacaine in penile dorsal nerve block for pediatric circumcision is stable, safe and reliable, it is worthy of popularization and application in clinic.
