PERIOPERATIVE MEDICINE
Association between Anesthesiologist Age and Litigation 574
Michael J. Tessler, Ian Shrier, and Russell J. Steele 
Three age groups of Canadian anesthesiologists, from postresidency to retirement, were examined for frequency of litigation. The oldest group had the highest frequency of litigation and greatest severity of injury in the litigations pursued.
Exceptionally Stable Fluorous Emulsions for the Intravenous Delivery of Volatile General Anesthetics 580
Jun-Pil Jee, Maria C. Parlato, Mark G. Perkins, Sandro Mecozzi, and Robert A. Pearce 
A new dibranched fluorinated polymer allows the formation of exceptionally stable emulsions for the intravenous delivery of sevoflurane.
Delayed Environmental Enrichment Reverses Sevoflurane-induced Memory Impairment in Rats 586
Jennifer Shih, Laura D. V. May, Heidi E. Gonzalez, Elaine W. Lee, Rehan S. Alvi, Jeffrey W. Sall, Vinuta Rau, Philip E. Bickler, Gopal R. Lalchandani, Marianna Yusupova, Elliott Woodward, Heejae Kang, Alan J. Wilk, Colleen M. Carlston, Mortay V. Mendoza, Jeremy N. Guggenheim, Maximilian Schaefer, Allison M. Rowe, and Greg Stratmann 
Behavioral consequences of anesthesia-induced developmental neurotoxicity are treatable. Sevoflurane, but not tissue injury, caused a short-term memory deficit that was reversed by delayed environmental enrichment.
Surgery and Brain Atrophy in Cognitively Normal Elderly Subjects and Subjects Diagnosed with Mild Cognitive Impairment 603
Richard P. Kline, Elizabeth Pirraglia, Hao Cheng, Susan De Santi, Yi Li, Michael Haile, Mony J. de Leon, and Alex Bekker; for the Alzheimer's Disease Neuroimaging Initiative 
The authors explored postoperative changes in brain volume (total gray matter and hippocampus) and cognition using the Alzheimer's Disease Neuroimaging Initiative database. Analyzed regions showed increased rates of atrophy in surgical versus  nonsurgical subjects.
Advance Targeted Transfusion in Anemic Cardiac Surgical Patients for Kidney Protection: An Unblinded Randomized Pilot Clinical Trial 613
Keyvan Karkouti, Duminda N. Wijeysundera, Terrence M. Yau, Stuart A. McCluskey, Christopher T. Chan, Pui-Yuen Wong, Mark A. Crowther, Siroos Hozhabri, and W. Scott Beattie 
In 60 anemic cardiac surgical patients, prophylactic transfusion of 2 erythrocyte units 1 to 2 days before surgery reduced perioperative anemia and erythrocyte transfusions. Studies assessing the renal protective effects of this intervention are warranted.
A Prospective Randomized Equivalence Trial of the GlideScope Cobalt® Video Laryngoscope to Traditional Direct Laryngoscopy in Neonates and Infants 622
John E. Fiadjoe, Harshad Gurnaney, Nicholas Dalesio, Emily Sussman, Huaqing Zhao, Xuemei Zhang, and Paul A. Stricker 
In a population of healthy infants with normal airway anatomy, tracheal intubation was performed with similar times and success rates using the GlideScope Cobalt® video laryngoscope (Verathon Medical, Bothell, WA) as compared with direct laryngoscopy with a Miller 1 blade.
Comparative Effectiveness of the C-MAC Video Laryngoscope versus  Direct Laryngoscopy in the Setting of the Predicted Difficult Airway 629
Michael F. Aziz, Dawn Dillman, Rongwei Fu, and Ansgar M. Brambrink 
A randomized controlled trial that compared conventional Macintosh blade laryngoscopy with the C-MAC® video laryngoscope (Karl Storz, Tuttlingen, Germany) in patients presenting with a predicted difficult airway found that using the C-MAC video laryngoscope improves intubation success at first attempt.
Pulmonary Hypertension in Lambs Transfused with Stored Blood Is Prevented by Breathing Nitric Oxide 637
David M. Baron, Binglan Yu, Chong Lei, Aranya Bagchi, Arkadi Beloiartsev, Christopher P. Stowell, Andrea U. Steinbicker, Rajeev Malhotra, Kenneth D. Bloch, and Warren M. Zapol 
In this study, an ovine model of autologous blood storage and transfusion was developed. The model was utilized to examine the hemodynamic effects of blood transfusion after storage of erythrocytes for prolonged periods. SUPPLEMENTAL DIGITAL CONTENT IS AVAILABLE IN THE TEXT 
Choice of Anesthetic Combination Determines Ca2+Leak after Ischemia-Reperfusion Injury in the Working Rat Heart: Favorable versus  Adverse Combinations 648
Michael Zaugg, Lianguo Wang, Liyan Zhang, Phing-How Lou, Eliana Lucchinetti, and Alexander S. Clanachan 
The choice of anesthetic combination determines the postischemic sarcoplasmic Ca2+leak and intracellular Ca2+overload after ischemia-reperfusion injury in the working rat heart. Propofol antagonizes sevoflurane protection but does not block remifentanil protection. SUPPLEMENTAL DIGITAL CONTENT IS AVAILABLE IN THE TEXT 
Intraoperative Hypotension and Perioperative Ischemic Stroke after General Surgery: A Nested Case-control Study 658
Jilles B. Bijker, Suzanne Persoon, Linda M. Peelen, Karel G. M. Moons, Cor J. Kalkman, L. Jaap Kappelle, and Wilton A. van Klei 
This study supports the hypothesis that intraoperative hypotension, especially when defined as a decrease in mean blood pressure relative to baseline, can influence the evolution of postoperative strokes by compromising blood flow to ischemic areas.
Continuous Femoral Nerve Blocks: Decreasing Local Anesthetic Concentration to Minimize Quadriceps Femoris Weakness 665
Maria Bauer, Lu Wang, Olusegun K. Onibonoje, Chad Parrett, Daniel I. Sessler, Loran Mounir-Soliman, Sherif Zaky, Viktor Krebs, Leonard T. Buller, Michael C. Donohue, Jennifer E. Stevens-Lapsley, and Brian M. Ilfeld 
For continuous femoral nerve blocks, the authors found no evidence that local anesthetic concentration and volume influence block characteristics, specifically quadriceps weakness, suggesting that local anesthetic dose (mass) is the primary determinant of perineural infusion effects.
Xenon Attenuates Hippocampal Long-term Potentiation by Diminishing Synaptic and Extrasynaptic N  -methyl-D-aspartate Receptor Currents 673
Stephan Kratzer, Corinna Mattusch, Eberhard Kochs, Matthias Eder, Rainer Haseneder, and Gerhard Rammes 
In acute murine hippocampal brain slices, the inhalational anesthetic xenon impaired long-term potentiation and N  -methyl-D-aspartate receptor-mediated neurotransmission.
Influence of Supervision Ratios by Anesthesiologists on First-case Starts and Critical Portions of Anesthetics 683
Richard H. Epstein and Franklin Dexter 
The number of operating rooms that an anesthesiologist can supervise concurrently is determined by the probability of multiple simultaneous critical portions of cases (i.e.  , requiring presence) and the availability of cross-coverage. The timing and duration of critical portions of cases was determined from 1 yr of data at a tertiary care hospital and the percentages of days with at least one supervision lapse occurring at supervision ratios between 1:1 and 1:3 were determined. Even at a supervision ratio of 1:2, lapses occurred on 35% of days. Decreasing the supervision ratio from 1:2 to 1:3 has a large impact on supervision lapses during first case starts. These lapses occur even after excluding case starts, lunch relief, and breaks. To mitigate morning lapses, either staggered starts or additional anesthesiologists working at the start of the day would be required.
CRITICAL CARE MEDICINE
Molecular Changes Induced in Rat Liver by Hemorrhage and Effects of Melanocortin Treatment 692
Caterina Lonati, Andrea Sordi, Daniela Giuliani, Luca Spaccapelo, Patrizia Leonardi, Andrea Carlin, Alessandra Ottani, Maria Galantucci, Paolo Grieco, Anna Catania, and Salvatore Guarini 
Melanocortins restore blood pressure, reverse metabolic acidosis, and prevent hemorrhage-induced alterations in liver gene expression. Melanocortins could be an effective adjunctive therapy in hemorrhagic shock. SUPPLEMENTAL DIGITAL CONTENT IS AVAILABLE IN THE TEXT
