Efficacy of intraoperative epidural dexamethasone and bupivacaine in reduction of pain and disability following lumbar discectomy.

Background: In lumbar disc herniation, although surgery can provide relief from pain in the low back and lower extremities, many drugs can provide more relief; thus, the aim was the evaluation of epidural dexamethasone and bupivacaine efficacy in lumbar disc herniation surgery.

Methods: A total of 42 cases were evaluated in a triple-blind randomized clinical trial study. Patients were divided into intervention and control groups based on permuted block randomization.

Evaluation of the prognostic value of multimodal intraoperative monitoring in posterior fossa surgery patients with cerebellopontine angle tumors.

The aim of this study was to compare the outcomes of four intraoperative monitoring approaches in order to compare their prognostic value in surgical complications of the facial nerve. This quasi-experimental study was conducted on 25 patients with Cerebellopontine Angle (CPA) tumors, who were hospitalized in the Valiasr Hospital, affiliated to the Arak University of Medical Sciences, Arak, Iran. The degree of the facial nerve paralysis was assessed based on the House-Brackmann (HB) facial nerve grading system.
