[Hemodynamic parameters and blood-free surgical field with nitroglycerin in maxillofacial surgery].

73 oral facial surgery have been performed using controlled-hypotension induced with nitroglycerin (NTG) to reduce surgical bleeding. Surgical bleeding has been reduced in more than 45% of cases. But frequent lack of correlation between blood pressure, heart beat and bleeding might imply vascular reflex mechanisms induced by controlled-hypotension using NTG. Hemodynamic parameters such as blood pressure and heart rate seem to be insufficient to monitor controlled hypotension efficiency on surgical bleeding. The use of peroperative tissues blood flow monitoring may help for the better understanding of surgical bleeding during controlled-hypotension using NTG.
