Surgical treatment of lumbar intervertebral disc herniation is a critical procedure due to the proximity of the operation field to neural structures. Providing a bloodless field and optimizing surgeon vision is of high value in this regard. Total intravenous anesthesia with propofol and inhalation anesthesia with isoflurane are both used in spine surgeries. Both of these agents have vasodilator properties that could be benefited in inducing controlled hypotension as a blood sparing technique.

Methods: After obtaining ethics approval and informed consent, 88 Iranian patients with American society of anesthesiology score 1 and 2 were randomly divided into two groups. The ISO group received isoflurane and the PRO group received propofol as the main anesthetic agent. Hemodynamic changes, intraoperative bleeding, urinary output, and surgeon satisfaction score were recorded. Results: The two groups were similar in demographic characteristics (for age P = 0.072; for gender P = 0.286). The ISO group had significantly lower blood pressure after 30 minutes of anesthesia (P = 0.01). Intraoperative bleeding in terms of qualitative and quantitative measures was lower in the ISO group (P = 0.001). Isoflurane anesthesia was also associated with a higher surgeon satisfaction score (P = 0.01).
