Analysis of the analgesic effect and safety of dexmedetomidine combined with dorsal penile nerve block in children with circumcision

Abstract

Objective To investigate the effect and safety of dexmedetomidine combined with dorsal penile nerve block for circumcision in children. Methods 130 children with circumcision were divided into the observation group and the control group according to the digital table, 65 cases in each group. The control group received total inhalation of seven halothane anesthesia, and the observation group received dexmedetomidine combined with dorsal penile nerve block anesthesia. The efficacy and safety of the two groups were compared. Results In the observation group after induction, the mean arterial pressure[(69.89±5.24)mmHg], awake and mean arterial pressure[(70.14±5.30)mmHg], rhythm of the heart after induction[(100.36±10.67)times/min], the rhythm of the heart when they woke up[(102.64±10.58)times/min], blood oxygen saturation after induction[(98.25±0.63)%], awake and blood oxygen saturation[(98.64±0.66)%]and other signs of vital signs had no statistically significant differences compared with the control group(F=0.130, 0.215, 0.548, 0.613, 0.106, 0.257, all P>0.05). In the observation group, the eyelash reflex disappearing time, operation time, awakening time were(23.16±2.13)s, (9.70±1.24)min, (10.03±1.27)min, respectively, which in the control group were(27.98±3.87)s, (11.88±2.87)min, (11.89±3.87)min, respectively, there were statistically significant differences between the two groups(t=8.797, 5.621, 6.633, all P<0.05). In the observation group, the postoperative agitation score, sedation score, pain score were(2.75±1.25)points, (1.11±0.13)points, (5.26±1.44)points, respectively, which in the control group were(6.78±2.89)points, (1.11±0.13)points, (8.97±3.64)points, respectively, there were statistically significant differences between the two groups(t=10.318, 17.236, 10.318, all P<0.05). Conclusion Application of dexmedetomidine combined with penile dorsal nerve block anesthesia in pediatric circumcision takes effect quickly, children with stable vital signs, less postoperative agitation, it is worthy of popularization and application in clinic.
