BACKGROUND Although early reviews of clinical findings were mostly negative, there is still a widespread belief for the efficacy of preemptive analgesia among clinicians. In this study, we evaluated whether the preemptive use of ketamine decreases post operative pain in patients undergoing appendectomy. METHODS In double-blind, randomized clinical trials, 80 adult male patients undergoing an ...

BACKGROUND US soldiers injured in Iraq, and civilian burn trauma patients are treated at the US Army Institute of Surgical Research. Burn patients experience extreme pain during wound care, and they typically receive opioid analgesics and anxiolytics for debridement. Virtual Reality (VR) has been applied as an adjunct to opioid analgesics for procedural pain. We describe the first use of ketami...

Ketamine is an IV anesthetic with N-methyl-d-aspartate receptor (NMDAR)-blocking properties. However, it is still unclear whether ketamine's general anesthetic actions are mediated primarily via blockade of NMDAR. Functional NMDARs are composed by the assembly of a GluRzeta1 (NR1) subunit with GluRepsilon (GluRepsilon1-4; NR2A-D) subunits, which confer unique properties on native NMDARs. We hyp...

BACKGROUND Propofol-ketamine anesthesia is a room air, spontaneous ventilation (RASV), dissociative intravenous (IV) sedation technique reported to have a near-zero postoperative nausea and vomiting (PONV) rate. Clonidine premedication has been reported to control blood pressure intra- and postoperatively, as well as to reduce the requirements for hypnotic agents. The bispectral index (BIS) mon...

Objective—Suicidal ideation is a medical emergency, especially when severe. Little research has been done on pharmacological interventions that could address this problem. Ketamine, an Nmethyl-D-aspartate (NMDA) antagonist, has been reported to have antidepressant effects within hours. We examined the effects of a single dose of ketamine on suicidal ideation in subjects with treatment-resistant...

Background. US soldiers injured in Iraq, and civilian burn trauma patients are treated at the US Army Institute of Surgical Research. Burn patients experience extrem pain during wound care, and they typically receive opioid analgesics and anxiolytics for debridement. Virtual Reality (VR) has been applied as an adjunct to opioid analgesics for procedural pain. We describe the first use of ketami...

BACKGROUND Tetralogy of fallot (TOF) is the most common cyanotic congenital heart disease. Anesthesia induction is a challenging issue in these patients due to the risk of worsening hypoxemia following decrease in pulmonary blood flow. We evaluated the effect of three anesthetic induction regimens on the arterial oxygen saturation (SaO2%) in children with TOF. METHODS Seventy six children age...

Introduction: The use of ketamine in the prehospital setting has increased with EMS providers. Adverse effects administration have not been well-established trauma population. objective this study was to evaluate pre-hospital on patients presenting a Level 1 center. This hypothesized that respiratory depression or oversedation from would increase number ED (Emergency Department) intubations. Me...

BACKGROUND Tonsillectomy is one of the most common surgeries in children and posttonsillectomy pain and agitation management is a great challenge for anesthesiologists. OBJECTIVES The aim of this study was to compare the efficacy of a single dose of ketamine combined with paracetamol with paracetamol alone in the management of postoperative pain in tonsillectomy. MATERIALS AND METHODS In th...
