Opioids and non-steroidal anti-inflammatory drugs are used commonly to manage pain in the early phase of spinal cord injury (SCI). Despite its analgesic efficacy, however, our studies suggest that intrathecal morphine undermines locomotor recovery and increases lesion size in a rodent model of SCI. Similarly, intravenous (IV) morphine attenuates locomotor recovery. ⋯ These data suggest that morphine use is contraindicated in the acute phase of a spinal injury. Faced with a lifetime of intractable pain, however, simply removing any effective analgesic for the management of SCI pain is not an ideal option. Instead, these data underscore the critical need for further understanding of the molecular pathways engaged by conventional medications within the pathophysiological context of an injury.

Opioids are the mainstay of pain management for acute postsurgical pain. Oral oxycodone is an opioid that can provide effective acute postoperative pain relief. ⋯ Oral oxycodone appears to offer safe and effective postoperative analgesia, and is a well-accepted and reasonable alternative to standard intravenous opioid analgesics.Key words: Postoperative, pain, analgesia, oral oxycodone, opioid.

Randomized Controlled TrialEffects of transcutaneous electrical acupoint stimulation at different frequencies on perioperative anesthetic dosage, recovery, complications, and prognosis in video-assisted thoracic surgical lobectomy: a randomized, double-blinded, placebo-controlled trial.
Transcutaneous electrical acupoint stimulation (TEAS), a non-invasive and non-pharmacological adjunctive intervention for perioperative analgesia, may also reduce the incidence of postoperative pulmonary complications. The effect of TEAS on video-assisted thoracic surgical (VATS) patients is still unknown, however. The purpose of this study was to investigate the effects of TEAS of different frequency on perioperative anesthetic dosage, recovery, complications, and prognosis for patients undergoing VATS lobectomy. ⋯ TEAS is a safe noninvasive adjunctive intervention for anesthesia management among patients undergoing VATS lobectomy. TEAS at 2/100 Hz can reduce intraoperative opioid dosage and slow the decrease of PaO2 during one-lung ventilation. It can also effectively reduce pain score, extubation time, and PACU stay immediately after surgery. Further, 100 Hz TEAS can reduce PONV morbidity.

Comparative StudyContinuous intravenous analgesia with fentanyl or morphine after gynecological surgery: a cohort study.
This retrospective study aims to compare postoperative pain relief offered by continuous intravenous infusion of either fentanyl or morphine. ⋯ In low-risk patients undergoing open gynecological surgery, continuous intravenous infusion of both fentanyl and morphine for postoperative pain relief is effective. In our cohort of patients, continuous intravenous infusion of fentanyl was associated with lower need for analgesic rescue drug, faster bowel recovery and shorter hospital length of stay.

Intrathecal therapy is an important part of the pain treatment algorithm for chronic disease states. The use of this option is a viable treatment strategy, but it is inherent for pain physicians to understand risk assessment and mitigation. In this manuscript, we explore evidence and mitigating strategies to improve safety with intrathecal therapy. ⋯ Intrathecal therapy is a viable and relatively safe option for the treatment of cancer- and noncancer-related pain. Continued research and expert opinion are required to improve our current pharmacokinetic and pharmacodynamic model of intrathecal drug delivery, as this will undoubtedly improve safety and efficacy.
