VASOVAGAL REACTIONS IN NEUROAXIAL ANESTHESIA AND THEIR PROPHYLAXIS
Abstract
The rate, character and peculiarities of the vasovagal reactions (VVR) while application of neuroaxial anesthesia in 800 patients were analyzed. In 720 (90%) patients a spinal anesthesia was conducted, in 80 (10%) – catheterization of epidural space. On the stage of access to subdural/еpidural space before the anesthetic injection the VVR signs were noted in 67 (8.4%) patients, including hypotension - in 42 (62.7%), bradycardia- in 26 (38.8%), combination of bradycardia and hypotension - in 20 (29.8%), short-term loss of consciousness - in 3 (4.5%), generalized convulsions - in 1. Algorithm of the urgent medical help provision while the VVR occurrence is proposed.
