Physiologic changes during tourniquet use in children.
The hemodynamic and metabolic effects of unilateral tourniquet use were assessed in 30 children. Intraoperative hyperthermia, tachycardia, endtidal CO2, and lactic acid concentration were measured before and after tourniquet inflation. Maximum changes in temperature and pulse rate occurred in patients who had tourniquet application time lasting greater than 75 min. Lactate and endtidal CO2 levels were also significantly increased in the same group of patients.
