BACKGROUND The aim of this study was to investigate the role of chemokine (C-X-C motif) ligand 13 (CXCL13) in morphine tolerance in rats with cancer-induced bone pain (CIBP). MATERIAL AND METHODS We established a rat CIBP model and a rat CIBP-morphine tolerance (BM) model. BM rats were intrathecally administered rmCXCL13, neutralizing anti-CXCL13, and normal saline, while the control group rats underwent a sham operation and were injected with normal saline. The morphine analgesia was assessed by measuring mechanical withdrawal threshold (MWT) and mechanical withdrawal duration (MWD) at various time points...

PURPOSE: Inadequate analgesia following abdominal surgery may affect outcome. Data in patients undergoing liver surgery suggested that postoperative coagulopathy might delay epidural catheter removal. Thus, alternative analgesic techniques should be evaluated. METHODS: We compared the analgesic efficacy of intraoperative intrathecal morphine [single injection 4 µg/kg before skin incision (ITM group, n = 23)] to intravenous opioids [iv remifentanil infusion during surgery followed by i...

BACKGROUND: Posterior spinal fusion to correct idiopathic scoliosis is associated with severe postoperative pain. Intrathecal morphine is commonly used for analgesia after adolescent posterior spinal fusion; however, anticipating and managing the increase in pain scores after resolution of analgesic effect of intrathecal morphine analgesia is challenging. In 2014, we developed a clinical protocol detailing both the administration of intrathecal morphine intraoperatively and the transition to routine, scheduled oral analgesics at 18 h postoperatively...

BACKGROUND: Spinal anesthesia with intrathecal morphine is a reliable, easy to apply, and cost effective method for controlling pain after total knee arthroplasty (TKA). However, postoperative nausea and vomiting (PONV) is a major concern. 5-Hydroxytryptamine receptor 3 (5-HT3) antagonists like ondansetron and ramosetron are commonly used for preventing PONV, but the optimal choice remains unclear. We conducted a study to assess the effectiveness of ramosetron and ondansetron, hypothesizing that the longer acting ramosetron may be better than ondansetron in the first 48 hours after TKA, performed with spinal anesthesia and intrathecal morphine...

Concerns over interactions between analgesics and experimental outcomes are a major reason for withholding opioids from rats undergoing surgical procedures. Only a fraction of morphine injected intravenously reaches receptors responsible for analgesia in the central nervous system. Intrathecal administration of morphine may represent a way to provide rats with analgesia while minimizing the amount of morphine injected. This study aimed to assess whether morphine injected intrathecally via direct lumbar puncture provides sufficient analgesia to rats exposed to acute surgical pain (caudal laparotomy)...

INTRODUCTION: Motor cortex stimulation is a well-known treatment modality for refractory neuropathic pain. Nevertheless, some cases of therapeutic failure have been described but alternative therapies for these cases are rarely reported. CASE REPORT: The patient presented with neuropathic pain in his right arm due to a cervical syrinx which was surgically treated by a shunt in 2003 with no clinical improvement. As alternative therapy, after an evaluation by repetitive magnetic transcranial stimulation with significant benefit, motor cortex stimulation was successfully implanted in 2004...

Opioids and NSAIDs are commonly used to manage pain in the early phase of spinal cord injury (SCI). Despite its analgesic efficacy, however, our studies suggest that intrathecal (i.t.) morphine undermines locomotor recovery and increases lesion size in a rodent model of SCI. Similarly, intravenous (i.v.) morphine attenuates locomotor recovery. The current study explores whether i.v. morphine also increases lesion size after a spinal contusion (T12) injury, and quantifies the cell types that are affected by early opioid administration...

BACKGROUND: Subarachnoid block is the preferred technique for providing anesthesia for patients undergoing cesarean section. Various pharmacological agents in added to local anesthetics (LA) modify their original effects in terms of block characteristics and quality of analgesia. However, there is ongoing debate about this practice of using adjuncts with LA. We tested whether addition of lipophilic versus lipophobic opioids to LA gives any clinical benefits to maternal and fetal outcome when used in these patients requiring spinal anesthesia...

PURPOSE: Intrathecal morphine provides superior pain control for patients undergoing cesarean delivery when compared to intravenous opioid patient-controlled analgesia. However, no study has assessed the overall cost associated with each modality as a primary outcome. The aim of this study is to determine the overall cost of each modality for the first 24 h post cesarean delivery. METHODS: Charts of patients undergoing cesarean delivery at our institution from January 1, 2014 to December 31, 2014 were reviewed...

INTRODUCTION: Epidural analgesia is commonly used for management of pain during childbirth. Need for emergent Caesarean section e.g. because of signs of foetal distress or lack of progress is however not an uncommon event. In females having an established epidural; general anaesthesia, top-up of the epidural or putting a spinal are all possible options. Dosing of the spinal anaesthesia in females having epidural is a matter of discussion. PRESENTATION OF CASE: We describe a healthy 32 years, 0 para mother in gestation week 36 having labour epidural analgesia but due to foetal distress scheduled for an emergent Caesarean section category 2 that developed upper extremity weakness and respiratory depression after administration of standard dose high density bupivacaine/morphine/fentanyl intrathecal anaesthesia...

BACKGROUND: The appropriate dose of intrathecal morphine for post-cesarean analgesia is unclear. With the inclusion of routine non-steroidal anti-inflammatory drugs, the required dose of morphine may be significantly less than the 200-300μg common a decade ago. We performed a two-center, prospective, randomized, blinded trial comparing three doses of intrathecal morphine, combined with routine intravenous ketorolac, in 144 healthy women undergoing elective cesarean delivery. METHODS: Patients received an intrathecal injection of hyperbaric bupivacaine 12mg, fentanyl 15μg and a randomized dose of 50, 100, or 150μg morphine in a volume of 2...

BACKGROUND: The effectiveness of transversus abdominis plane (TAP) blocks for acute pain relief after caesarean section, in comparison to normal practice, remains uncertain. METHODS: Electronic literature databases were searched from inception to May 2016 for randomised controlled trials that assessed the effectiveness of TAP blocks following caesarean section. Trials were eligible if comparisons were made against no block or placebo, and/or intrathecal morphine...

The conversion of high-dose intravenous (IV) opioids to an equianalgesic epidural (EP) or intrathecal (IT) dose is a common clinical dilemma for which there is little evidence to guide practice. Expert opinion varies, though a 100 IV:10:EP:1 IT conversion ratio is commonly cited in the literature, especially for morphine. In this study, the authors surveyed 724 pain specialists to elucidate the ratios that respondents apply to convert high-dose IV morphine, hydromorphone, and fentanyl to both EP and IT routes...

UNLABELLED: Complex regional pain syndrome (CRPS) presents a therapeutic challenge due to its many presentations and multifaceted pathophysiology. There is no approved treatment algorithm and clinical interventions are often applied empirically. In cases of CRPS where symptoms are localized to an extremity, a targeted treatment is indicated. We describe the use of intrathecal bupivacaine monotherapy, delivered through a retrograde catheter, in the treatment of CRPS affecting the lower extremity...

BACKGROUND: Morphine is the most common opioid injected into the intrathecal space for postoperative analgesia following cesarean delivery, but ongoing medication shortages have resulted in limited availability. One proposed morphine alternative is hydromorphone. Studies investigating its use in post-cesarean analgesia are limited. This study was conducted to determine the median effective dose of intrathecal hydromorphone 12h postpartum. METHODS: Twenty healthy women undergoing elective cesarean delivery were recruited into this study...

A 1-week-old infant was brought to a regional hospital with a history of recurrent seizures following lower abdominal septic skin infection. She was found to have neonatal tetanus, and a spatula test was positive. The tetanus infection was associated with a superficial skin infection, common in neonates. Treatment included sedatives (diazepam, chlorpromazine, phenobarbitone and morphine), muscle relaxants, antibiotics and ventilation in the neonatal intensive care unit. Intrathecal and intramuscular immunoglobulin were given, and the wound was treated...

Opioid analgesics have less efficacy in diabetic neuropathy treatment, and tolerance often occurs after chronic usage. Given that thalidomide can potentiate the morphine efficacy in diabetic neuropathy treatment, we investigated the effects of intrathecal administrations of thalidomide on morphine tolerance during the treatment of diabetic neuropathy. We found that intrathecal administrations of thalidomide (25 mg/kg/ml) potentiated the analgesic effects of morphine on mechanical hyperalgesia and prevented the development of morphine tolerance...

More than 240 million opioid prescriptions are dispensed annually to treat pain in the US. The use of opioids is commonly associated with opioid tolerance (OT) and opioid-induced hyperalgesia (OIH), which limit efficacy and compromise safety. The dearth of effective way to prevent or treat OT and OIH is a major medical challenge. We hypothesized that mesenchymal stem cells (MSCs) attenuate OT and OIH in rats and mice based on the understanding that MSCs possess remarkable anti-inflammatory properties and that both OT and chronic pain are associated with neuroinflammation in the spinal cord...
