An Update on Nonopioids: Intravenous or Oral Analgesics for Perioperative Pain Management.

Despite an appreciation for many unwanted physiologic effects from inadequate postoperative pain relief, moderate to severe postoperative pain remains commonplace. Although treatment options have evolved in recent years, the use of nonopioid analgesics agents can reduce acute pain-associated morbidity and mortality. This review focuses on the importance of effective postoperative nonopioid analgesic agents, such as acetaminophen, nonsteroidal anti-inflammatory agents, gabapentinoid agents, NMDA antagonists, alpha 2 agonists, and steroids, in opioid sparing and enhancing recovery.

Pharmacology of Antiemetics: Update and Current Considerations in Anesthesia Practice.

Postoperative nausea and vomiting (PONV) is associated with delayed recovery and dissatisfaction after surgical procedures. A key component to management is identifying risk factors and high-risk populations. Advances in pharmacologic therapeutics have resulted in agents targeting different pathways associated with the mediation of nausea and vomiting.

Pulmonary Vasodilators and Anesthesia Considerations.

Pulmonary hypertension (PH) is a complex disease process of the pulmonary vasculature system characterized by elevated pulmonary arterial pressures. Patients with PH are at increased risk for morbidity and mortality, including intraoperatively and postoperatively. Appreciation by the clinical anesthesiologist of the pathophysiology of PH is warranted.

Adjuvant Agents in Regional Anesthesia in the Ambulatory Setting.

Purpose Of Review: A majority of surgical practice has involved ambulatory centers with the number of outpatient operations in the USA doubling to 26.8 million per year. Local anesthesia delivery provides numerous benefits, including increased satisfaction, earlier discharge, and reduction in unplanned hospital admission.

The Role of Acupuncture in Pain Management.

Acupuncture is a traditional Chinese practice of medicine that has gained popularity in Western culture and around the world. It involves the insertion of thin needles into the skin to stimulate nerves, muscles, and connective tissues throughout the body with the goal of alleviating pain, tension, and stress. More broadly, acupuncture is actually a family of different procedures.

New Pain Management Options for the Surgical Patient on Methadone and Buprenorphine.

Perioperative management of patients receiving opioid addiction therapy presents a unique challenge for the anesthesiologist. The goal of pain management in this patient population is to effectively manage postoperative pain, to improve patient satisfaction and outcomes, and to reduce the cost of health care. Multimodal analgesics, including nonsteroid anti-inflammatory drugs, intravenous acetaminophen, gabapentanoid agents, and low-dose ketamine infusions, have been used to improve postoperative pain and to reduce postoperative opioid use.

Botulinum Toxin: Pharmacology and Therapeutic Roles in Pain States.

Botulinum toxin, also known as Botox, is produced by Clostridium botulinum, a gram-positive anaerobic bacterium, and botulinum toxin injections are among the most commonly practiced cosmetic procedures in the USA. Although botulinum toxin is typically associated with cosmetic procedures, it can be used to treat a variety of other conditions, including pain. Botulinum toxin blocks the release of acetylcholine from nerve endings to paralyze muscles and to decrease the pain response.

New Labor Pain Treatment Options.

Presently, the gold standard for pain control in laboring patients is neuraxial blockade, which includes a spinal, epidural, or a combined spinal-epidural technique. In conjunction with neuraxial blockade or by itself, some of the other agents employed related to labor pain include opioids, non-opioids, nitrous oxide, patient-controlled analgesia (PCA), and distraction therapy. Alternative treatments include acupuncture, hypnotism, yoga, exercise during pregnancy, hydrotherapy, transcutaneous electronic nerve stimulation, massage, and relaxation techniques.

96-hour methamphetamine self-administration in male and female rats: a novel model of human methamphetamine addiction.

Methamphetamine (MA) is a highly addictive psychostimulant drug of abuse for which no FDA-approved treatment exists. While high on MA, both male and female MA users report engaging in risky behaviors and are more likely to be involved in violent criminal activities and to engage in domestic and sexual violence. A unique aspect of MA is that it is typically used in binges.

Combinations of oxazepam and metyrapone attenuate cocaine and methamphetamine cue reactivity.

Background: We have previously reported that combining low doses of oxazepam and metyrapone (OX/MET) reduces intravenous cocaine self-administration without affecting stress-hormone levels. We hypothesized that the combination of OX/MET would also inhibit the reinstatement of cocaine or methamphetamine seeking induced by the presentation of a conditioned reinforcer and that stress hormone levels would not be influenced by this treatment.

Methods: Male rats were implanted with jugular catheters and trained to self-administer cocaine or methamphetamine during daily 2-h sessions.
