[Effects of surgery and anesthesia on serum immunoglobulins]

Serum immunoglobulins levels after surgery with and without anaesthesia are reported. No significant change was found after surgery without anaesthesia; significant changes of serum Ig (A,G,M) were observed in surgery with anaesthesia (60-180 m') group on day 1 following operation. This Ig decrease is probably due to a reduced immunologic response by long anaesthesia.
