A retrospective descriptive study was performed on 43 patients aged 8 to 12 years, who underwent scoliosis surgery in an elective way by means of modified Drummond´s posterior instrumentation technique under intravenous general anesthesia, with deliberate hypotension. The patients were operated on at "FranK País" International Scientific Orthopedic Center from October 2003 to October 2004. For applying general anesthesia, we used total intravenous technique with fentanil, midazolan and atracure, and hypotension was controlled with nitroglycerin. The findings were: blood losses amounting to 380+,-60 ml, with emergence from anesthesia at 1,20 +0,45 minutes and anesthesia reversion in 42 % of patients. The most frequent postoperative complications were pain in 44,4 %; oliguria in 20 % and bleeding in 6,6 % of patients respectively. It was concluded that the use of total intravenous anesthesia at low dose resulted in a shorter emergence from anesthesia, with anesthesia reversion in less than half of patients and reduced blood losses thanks to the use of controlled hypotension technique using nitroglycerin.
