From: The tryptophan kynurenine pathway, neopterin and IL-6 during vulvectomy and abdominal hysterectomy
The effect of anesthesia in patients undergoing vulvectomy and major abdominal surgery on perioperative levels of plasma tryptophan. Values are the mean and SEM. There was a significant within subject effect (P < 0.001). There was a significant decrease prior to induction and 30 minutes prior to the end of operation ( bracket P < 0.001). A significant increase occurred 30 minutes prior to the end of operation and 24 hours post operative (bracket P < 0.001).
