Perioperative Pharmacokinetics of Methadone in Adolescents 1153

Anshuman Sharma, Danielle Tallchief, Jane Blood, Thomas Kim, Amy London, and Evan D. Kharasch

A Gain-of-function Mutation in Adenylate Cyclase Confers Isoflurane Resistance in Caenorhabditis elegans  1162

Owais Saifee, Laura B. Metz, Michael L. Nonet, and C. Michael Crowder 

A gain-of-function mutation in an adenylate cyclase gene was discovered in the nematode Caenorhabditis elegans  that strongly reduces the potency of isoflurane. This mutation acts in neurons to regulate neurotransmitter release and isoflurane sensitivity

Perioperative Nerve Injury after Total Hip Arthroplasty: Regional Anesthesia Risk during a 20-year Cohort Study 1172

Adam K. Jacob, Carlos B. Mantilla, Hans P. Sviggum, Darrell R. Schroeder, Mark W. Pagnano, and James R. Hebl 

This cohort study determined the overall incidence of perioperative nerve injury after total hip arthroplasty to be 0.72. Use of neuraxial or peripheral regional anesthesia techniques did not increase the risk for perioperative nerve injury

Klaus Görlinger, Daniel Dirkmann, Alexander A. Hanke, Markus Kamler, Eva Kottenberg, Matthias Thielmann, Heinz Jakob, and Jürgen Peters 

First-line fibrinogen and/or prothrombin complex concentrate administration combined with point-of-care testing (thromboelastometry, impedance aggregometry) was associated with a markedly decreased incidence of allogeneic blood transfusion and of thrombotic/thromboembolic events in cardiovascular surgery

Pharmacogenomic Strain Differences in Cardiovascular Sensitivity to Propofol 1192

Thomas A. Stekiel, Stephen J. Contney, Richard J. Roman, Craig A. Weber, Anna Stadnicka, Zeljko J. Bosnjak, Andrew S. Greene, and Carol Moreno 

There is a pharmacogenomic difference in Dahl Salt Sensitive rats compared with Brown Norway control rats manifesting as enhanced cardiovascular sensitivity to propofol. This is attributable to altered renin gene function in the Dahl strain

Barbara L. Leighton, Michael H. Wall, Ellen M. Lockhart, Louise E. Phillips, and Amanda J. Zatta 

Amniotic fluid embolism patients who received recombinant factor VIIa had significantly worse outcomes than cohorts who did not receive recombinant factor VIIa. Death and major organ thrombosis were common in patients receiving recombinant factor VIIa

CRITICAL CARE MEDICINE

Neuroprotective Effect of Curcumin in an Experimental Rat Model of Subarachnoid Hemorrhage 1229

Chang-Po Kuo, Chueng-He Lu, Li-Li Wen, Chen-Hwan Cherng, Chih-Shung Wong, Cecil O. Borel, Da-Tong Ju, Chun-Mei Chen, and Ching-Tang Wu 

Treatment with multiple doses of curcumin after subarachnoid hemorrhage reduced mortality rate and improved functional and histological outcomes. Possible mechanisms include attenuation of glutamate level by preservation of glutamate transporter-1 protein expression and attenuation of oxidant stress

PAIN MEDICINE

Metabotropic Glutamate Receptor 5 Antagonism with Fenobam: Examination of Analgesic Tolerance and Side Effect Profile in Mice 1239

Michael C. Montana, Beth A. Conrardy, Laura F. Cavallone, Benedict J. Kolber, Lesley K. Rao, Suellen C. Greco, and Robert W. Gereau IV 

Daily administration of the mGlu5 antagonist fenobam for up to 2 weeks does not result in tolerance to fenobam’s analgesic effects and is well tolerated in mice

Buprenorphine Metabolites, Buprenorphine-3-glucuronide and Norbuprenorphine-3-glucuronide, Are Biologically Active 1251

Sarah M. Brown, Michael Holtzman, Thomas Kim, and Evan D. Kharasch 

Buprenorphine-3-glucuronide and norbuprenorphine-3-glucuronide had moderate to high affinity for human μ, δ, and/or nociceptin receptors, and elicited mild analgesic responses. Norbuprenorphine-3-glucuronide but not buprenorphine-3-glucuronide caused sedation and decreased tidal volume. Glucuronide metabolites may contribute to buprenorphine effects

Isozyme-specific Effects of Protein Kinase C in Pain Modulation 1261

Chengshui Zhao, Michael Leitges, and Robert W. Gereau IV 

This study utilizes a panel of genetically modified mice to demonstrate the diverse roles of the α, β, γ, and δ isoforms of protein kinase C in mediating hypersensitivity after inflammation or nerve injury

Rewarding Electrical Brain Stimulation in Rats after Peripheral Nerve Injury: Decreased Facilitation by Commonly Abused Prescription Opioids 1271

Eric E. Ewan and Thomas J. Martin 

Spinal nerve ligation in rats suppresses opioid facilitation of rewarding brain stimulation in a manner that is distinct from analgesia-related manipulations

Shifts in Cell-type Expression Accompany a Diminishing Role of Spinal P38-Mapkinase Activation over Time during Prolonged Postoperative Pain 1281

Liang Huang, Yong-Jing Gao, Jeffrey Wang, and Gary Strichartz 

During prolonged, postoperative pain, expression of activated mitogen-activated protein kinase p38 shifts from microglia to neurons. Inhibition of P-p38 at early times prevents later postoperative pain, but later inhibition causes only transient pain relief

EDUCATION

Case Scenario

Opioid Association with Serotonin Syndrome: Implications to the Practitioners 1291

Rahul Rastogi, Robert A. Swarm, and Trusharth A. Patel 

Serotonin syndrome is an uncommon but potentially life-threatening drug-induced toxicity, from interaction of opioids to other serotonergic agents. This toxic reaction can either be avoided, through knowing a patient’s detailed medicinal history, or be diagnosed early to prevent severe morbidity and mortality. It is even more critical for a practicing anesthesiologist to understand this entity, as the syndrome will be even more difficult to diagnose if secondary to overlapping symptoms from anesthetic. This case scenario focused on serotonin syndrome pathophysiology and management, and its association to routinely used opioids

Review Articles

Genetic Variation, β-blockers, and Perioperative Myocardial Infarction 1316

Peter Nagele and Stephen B. Liggett 

Perioperative myocardial infarction (MI) is a common and potentially fatal complication after noncardiac surgery. The use of β-adrenergic receptor blocking drugs for prevention and treatment of perioperative MI has become controversial. Interindividual genetic variation may determine the clinical response to β-blocker therapy. This article reviews the molecular, cellular, and physiologic consequences of polymorphisms in the adrenergic signaling pathway and CYP2D6 gene, and shows that these are likely relevant factors influencing efficacy, safety, and toxicity of β-blocker therapy in prevention and treatment of perioperative MI

Use of Concatemers of Ligand-Gated Ion Channel Subunits to Study Mechanisms of Steroid Potentiation 1328

Joe Henry Steinbach and Gustav Akk 

Neurosteroids potentiate responses to neurotransmitter at multiple sites on receptors. The authors review the use of covalently linked channel subunits to characterize the sites individually and provide insights into the mechanisms of neurosteroid potentiation

Structural Studies of the Actions of Anesthetic Drugs on the γ-Aminobutyric Acid Type A Receptor 1338

The γ-aminobutyric acid type A receptor is the major target for many clinically used anesthetic drugs. The authors describe the current state of knowledge of the structural rearrangements taking place during receptor activation and modulation
