Effectiveness and safety of morphine sulfate extended-release capsules in patients with chronic, moderate-to-severe pain in a primary care setting.
The purpose of this study was to determine the effectiveness and safety of morphine sulfate extended-release capsules among primary care patients with chronic, moderate-to-severe pain using a universal precautions approach that assessed and monitored risk for opioid misuse and abuse. ⋯ The results suggest that pain outcomes improved in patients with chronic, moderate-to-severe pain receiving morphine sulfate extended-release capsules within the context of a structured universal precautions approach in the primary care setting.

Tapentadol extended-release for treatment of chronic pain: a review.
Tapentadol is a centrally acting analgesic with a dual mechanism of action of mu receptor agonism and norepinephrine reuptake inhibition. Tapentadol immediate-release is approved by the US Food and Drug Administration for the management of moderate-to-severe acute pain. It was developed to decrease the intolerability issue associated with opioids. ⋯ Initial trials demonstrating efficacy in neuropathic pain suggest that tapentadol has comparable analgesic effectiveness and better gastrointestinal tolerability than opioid comparators, and demonstrates effectiveness in settings of inflammatory, somatic, and neuropathic pain. Gastrointestinal intolerance and central nervous system effects were the major adverse events noted. Tapentadol will need to be rigorously tested in chronic neuropathic pain, cancer-related pain, and cancer-related neuropathic pain.

To provide a review of local anesthetic (LA) agents and adjuncts, opioids and muscle relaxants, and their intraoperative effects and postoperative outcomes in intravenous regional anesthesia (IVRA). ⋯ Ropivacaine is effective for IVRA and improves postoperative analgesia. Muscle relaxants enhance the motor block and when combined with fentanyl allow for an equivalent quality of IVRA with 50% reduction in LA dose.

Renal and hepatic dysfunction or injury might be involved by ether based anesthetic and intravenous anesthetic drug or surgical stress. The purpose of this study is to compare the effect of moderate duration low-flow sevoflurane versus total intravenous anesthesia on renal and hepatic functions. ⋯ These results show that the renal and hepatic effect of moderate duration low-flow sevoflurane and total intravenous anesthesia is similar.

Route of administration for illicit prescription opioids: a comparison of rural and urban drug users.
Nonmedical prescription opioid use has emerged as a major public health concern in recent years, particularly in rural Appalachia. Little is known about the routes of administration (ROA) involved in nonmedical prescription opioid use among rural and urban drug users. The purpose of this study was to describe rural-urban differences in ROA for nonmedical prescription opioid use. ⋯ Alternative ROA are common among rural drug users. This finding has implications for rural substance abuse treatment and harm reduction, in which interventions should incorporate methods to prevent and reduce route-specific health complications of drug use.
