To the Editor.—Dr Lander and colleagues1have shown once again the value and safety of anesthesia for neonatal circumcision. In this study, local infiltration ring block or dorsal penile nerve block resulted in less heart rate elevation and less crying during the circumcision procedure. Outcome measures said to have been investigated included heart rate, respiratory rate, oxygen saturation, palmar sweat, sleep-wake states, crying, motor responses, and methemoglobin level. Only heart rate, crying, and methemoglobin levels were reported, and the reader assumes that no significant changes were found in the remaining parameters.
