ABSTRACT
STUDY DESIGN: Prospective study. OBJECTIVES: This study compared the early postoperative analgesic effects and the postoperative nausea and vomiting (PONV) associated with 3 methods of pain control after posterior spinal decompression. SUMMARY OF LITERATURE REVIEW: Spinal surgery causes severe postoperative pain. Efficient and safe methods for postoperative analgesia after spinal surgery are necessary. MATERIALS AND METHODS: To determine the clinical symptoms and to assess improvements in postoperative pain, 52 patients in whom single-level posterior lumbar decompression was planned were randomly assigned to 3 groups. For postoperative pain control, 18 patients received a preoperative single-shot epidural injection (SEI), 16 patients received a postoperative continuous epidural injection (CEI), and 18 patients received only postoperative intravenous patient-controlled analgesia (IV-PCA). Patient ratings of pain intensity (visual analog scale score from 0 [no pain] to 10 [most severe pain]), nausea (from 0 [no nausea] to 5 [severe nausea]), and vomiting (from 0 [no vomiting] to 5 [severe vomiting]) were recorded immediately after the operation and at 4 hours, 12 hours, 1 day, and 2 days postoperatively. RESULTS: The CEI group showed significantly enhanced analgesic effects, followed by the SEI group and the IV PCA group (p < 0.05). PONV due to postoperative pain control was more severe in the IV PCA group than in the other 2 groups (p < 0.05). CONCLUSIONS: Continuous epidural injection (CEI) is effective for postoperative pain control and minimizes the occurrence of PONV after posterior spinal decompression.

A schwannoma is a benign tumor that originates from the peripheral nerve sheath. Schwannomas occur most commonly in the head and neck region involving the brachial plexus and the spinal nerves. The lower limbs are less commonly affected. This paper presents a case of a patient with a schwannoma showing atypical localization at the digital nerve of the foot causing neurological symptoms.
