Anesthetic hypotension effects on neurologic outcome after hemilaminectomy
Veterinarians at Purdue University College of Veterinary Medicine reported on the Effect of Anesthesia-associated Hypotension on Neurologic Outcome in Dogs undergoing Hemilaminectomy in the February 15, 2017, JAVMA. The purpose of their study was to determine if hypotension was linked to neurologic outcome. The anesthesia records of 56 dogs with acute severe thoracolumbar intervertebral disc herniation (IVDH) and absent nociception were reviewed. Hypotension was defined as MAP < 60 or SAP < 80 mm Hg. Sixty-one percent of patients regained ambulation. Fifty- nine percent of patients experienced hypotension during anesthesia. Whether dogs regained motor or urinary function was not significantly associated with the occurrence of hypotension. However, normotension should be the goal in all patients undergoing general anesthesia.
