Review
Spinal cord stimulation for chronic non-cancer pain: a review of current evidence and practice.
Spinal cord stimulation provides analgesia through electrical stimulation of the dorsal column of the spinal cord via electrode leads placed into the epidural space. In traditional tonic stimulation, a painful sensation is replaced with paraesthesia. Spinal cord stimulation is effective in reducing neuropathic pain, enhancing function, and improving quality of life in different chronic pain conditions. ⋯ Results are encouraging to date, and they may provide superior analgesia and cover for deficiencies of traditional tonic stimulation. Although complications are not uncommon, they are rarely life threatening or permanently disabling. Nonetheless, device removal is occasionally needed.

Intravenous infusion of lignocaine has emerged in recent years as a feasible, cost-effective, and safe method to provide postoperative analgesia. There is, however, no literature about this perioperative pain control modality in Chinese patients. This study aimed to determine whether perioperative intravenous lignocaine safely reduces postoperative pain, shortens postoperative ileus, and reduces the length of hospital stay in laparoscopic colorectal surgery. ⋯ Intravenous lignocaine is a safe and effective postoperative analgesic in a Chinese population. It enhances the rehabilitation process for patients following laparoscopic resection of colorectal cancer.
