Abstract

A prospective, controlled, double-blinded investigation was conducted to evaluate whether infants undergoing circumcisions with 1% lidocaine dorsal penile nerve blocks experienced decreased stress as compared with those receiving saline solution injections or no injections. Stress was measured in terms of pulse rate and oxygen saturation on a pulse oximeter. A subjective grading scale was also developed to measure infant irritability. The total number in the study was 51 with 23 infants in the lidocaine group, 21 in the saline solution group, and 7 in the no injection group. The results of the study revealed an average increase of 28.8% in the pulse rate above baseline for the control infants (p less than 0.001) versus no significant change in the lidocaine group. The average oxygen saturation of the control groups decreased by 5.6% from baseline (p less than 0.001), and that of the lidocaine group decreased by 1.0%, which was not a significant change. The subjective data were gained by using a grading scale of 1 to 6 with 1 being the least irritable infant and 6 being the most irritable infant. The physician evaluation gave an average rating of 4.2 to the control group versus 2.4 for the lidocaine group (p less than 0.001). The nursing evaluation during the procedure gave an average rating of 4.2 to the control group versus 2.3 to the anesthetized group (p less than 0.001). The subjective evaluation of infants before and after the procedure was not significantly different. There were no major complications in any of the groups.
