T WO factors have increased interest in ketamine for postoperative analgesia. The first was the discovery of the N-Methyl-D-asparrate (NMDA) receptor and its role in central pain processing and spinal cord neural plasticity. 1 Ketamine is one of two clinically useful NMDA receptor antagonists available (the other is dextromethorphan). Ketamine binds non-competitively to the PCI, (phencyclidine)...

The purpose of this study was to determine whether intravenous ketorolac tromethamine could produce preemptive analgesia in patients undergoing laparoscopic gynecologic surgical procedures. Each patient's response to pain was measured by the mechanical visual analogue scale (M-VAS) and total analgesic use. By using a double-blind design, 49 patients were randomized into the preemptive group (n ...

Multimodal Management Of Acute Pain: The Role of IV NSAIDs A cute pain is common in hospitalized patients, particularly in postoperative patients. In fact, postoperative pain often is undertreated and is associated with poor outcomes, higher costs of care, poor patient satisfaction, and an increased risk for developing chronic pain syndromes. The failure to treat postoperative pain adequately i...

Successful ambulatory surgery is dependent on analgesia that is effective, has minimal adverse effects, and can be safely managed by the patient at home after discharge. A number of studies have identified that the provision of effective postoperative analgesia is inadequate for a significant proportion of patients. The following discussion details the current available analgesic options for am...

BACKGROUND The analgesic properties of ketamine are associated with its non-competitive antagonism of the N-methyl-D-aspartate receptor; these receptors exhibit an excitatory function on pain transmission and this binding seems to inhibit or reverse the central sensitization of pain. In the literature, the value of this anesthetic for preemptive analgesia in the control of postoperative pain is...

BACKGROUND Peripheral nerve blocks have become an increasingly popular form of anesthesia. Preemptive analgesia reduces central sensitization, postoperative pain, and analgesic consumption. Different additive has been used to prolong regional blockade and improve postoperative analgesia. AIM This study was conducted to evaluate whether preemptive ankle block using combination of ropivacaine a...
