Comparative Study Clinical Trial Controlled Clinical TrialRegional anesthesia during newborn circumcision. Effect on infant pain response.
A controlled, double-blind investigation was undertaken to determine whether regional anesthesia by dorsal penile nerve block (DPNB) could effectively minimize the pain and behavioral disruptions usually associated with newborn circumcision. Fifteen infants had DPNB with lidocaine, eight control infants had DPNB with saline, and eight additional control infants were circumcised without undergoing DPNB. Newborn distress was gauged by subjective observation, measurement of heart rate, and the percent of time spent crying in six sequential timed intervals during circumcision. ⋯ Infants who had DPNB with lidocaine cried 50 percent less during circumcision compared to combined controls (p less than 0.01). DPNB was easily administered, and there were no significant complications. Physicians who circumcise newborns have good reason to employ the technique of dorsal penile nerve block with lidocaine to minimize infant pain and distress.
