Abstract
Summary: Plasma arginine vasopressin concentrations were measured in eight healthy, full term male infants before and during circumcision. There was no change in mean (± S.E.) plasma arginine vasopressin level from the baseline period (2.1 ± 0.5 μ/ml) to 1–2 min after application of a crushing clamp on the dorsal foreskin (1.8 ± 0.7 μ/ml).
Speculation: Unlike adults, the healthy newborn appears to tolerate a painful stimulus without increased plasma arginine vasopressin.
