Surgical stress and neuroendocrine responses in infants and children.
We studied the stress hormone response to surgery in 42 infants and children. Plasma levels of the stress hormones ACTH, cortisol, beta-endorphin and arginine-vasopressin (AVP) were determined on three occasions, i.e., one day before surgery, 60 to 90 minutes after skin closure and on the day after surgery (anesthesia by halothane and nitrous oxide). We observed an increase in the levels of both ACTH and cortisol in most patients after surgery, although there was no correlation between them. Beta-endorphin levels, on the other hand, rose after surgery and correlated significantly with ACTH in 30 patients. A steep rise in AVP levels was found in 84% of the subjects, a phenomenon that could not have been due only to osmotic or cardiovascular stimuli. The values of all the stress hormones declined and normalized on the day after surgery. We conclude that routine surgery in infancy or childhood induces a dramatic, albeit transient, stimulation of neuroendocrine stress hormones.
