The Feasibility of Epicardial Echocardiography for Measuring Aortic Valve Area by the Continuity Equation
Anesth Analg 2009 108: 17-22. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Measurement of the aortic valve area is an important component of a comprehensive intraoperative echocardiographic examination during cardiac surgery involving the aortic valve. We demonstrate that epicardial echocardiography can be used as an intraoperative alternative or adjunct to transesophageal echocardiography for measuring the aortic valve area.

Intrathecal Morphine Preconditioning Induces Cardioprotection via Activation of Delta, Kappa, and Mu Opioid Receptors in Rats
Anesth Analg 2009 108: 23-29. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Intrathecal morphine at a dose 1/1000th of the IV dose, conferred the same cardioprotection as ischemic myocardial preconditioning. This finding might have implications for when neuroaxial analgesia is planned perioperatively for patients with coronary artery disease.

Incidence and Risk Factors for Perioperative Hyperglycemia in Children with Traumatic Brain Injury
Anesth Analg 2009 108: 81-89. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Hyperglycemia after traumatic brain injury (TBI) is associated with poor outcome. In this study of children with TBI undergoing urgent/emergent craniotomy, perioperative hyperglycemia was common and hypoglycemia was not rare. Perioperative hyperglycemia was predicted by age < 4 yr, severe TBI and the presence of multiple lesions that include subdural hematoma.

The Influence of Head and Neck Position on the Oropharyngeal Leak Pressure and Cuff Position of Three Supraglottic Airway Devices
Anesth Analg 2009 108: 112-117. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Oropharyngeal leak pressure of ProSeal laryngeal mask airway was significantly lower than that of laryngeal tube section or Cobra perilaryngeal airway in the neck extension and rotation position. In addition, on moving the head and neck from the neutral position use of the laryngeal tube section and Cobra perilaryngeal airway resulted in an increased incidence of gastric insufflation and difficulty in ventilation.

Arteriovenous Differences in Plasma Dilution and the Distribution Kinetics of Lactated Ringer's Solution
Anesth Analg 2009 108: 128-133. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The arteriovenous difference in plasma dilution in the forearm was reversed 2.5 min after infusing Ringer's lactate solution, whereas kinetic analysis showed a corresponding value for the whole body of 14-20 min. Distribution of Ringer's occurs at various rates in different body regions rather than being a fixed-rate single process.

Nicotinic Receptors Partly Mediate Brainstem Autonomic Dysfunction Evoked by the Inhaled Anesthetic Isoflurane
Anesth Analg 2009 108: 134-141. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Clinically relevant concentrations of isoflurane inhibit brainstem respiratory rhythmogenesis, prolong {gamma}-aminobutyric acid (GABA)ergic inhibitory postsynaptic currents (IPSC) and, in the meantime, reduce GABAergic IPSC frequency in cardiac vagal neurons. The decrease of the frequency of GABAergic IPSCs is partially dependent upon inhibition of presynaptic {alpha}4{beta}2 nicotinic receptors. These mechanisms may contribute to cardiorespiratory homeostatic autonomic regulation impairment induced by isoflurane.

Propofol and Isoflurane Enhancement of Tonic Gamma-Aminobutyric Acid Type A Current in Cardiac Vagal Neurons in the Nucleus Ambiguus
Anesth Analg 2009 108: 142-148. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This study demonstrates that the general anesthetics propofol and isoflurane enhance phasic and tonic {gamma}-aminobutyric acid type A currents in cardiac vagal neurons, which is likely an important mechanism responsible for the changes of heart rate and autonomic regulation during general anesthesia.

Competitive Substrates for P-Glycoprotein and Organic Anion Protein Transporters Differentially Reduce Blood Organ Transport of Fentanyl and Loperamide: Pharmacokinetics and Pharmacodynamics in Sprague-Dawley Rats
Anesth Analg 2009 108: 149-159. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: These findings suggest that transport proteins variably regulate fentanyl and loperamide pharmacokinetics and pharmacodynamics and may provide potential targets for therapeutics designed to modulate individual responses to opioids. The interindividual variability of fentanyl response may be related to currently unappreciated transporter interactions with other drugs, such as statins or variable transporter expression, thus affecting pharmacodynamics.

Modeling the Gabaergic Action of Etomidate on the Thalamocortical System
Anesth Analg 2009 108: 160-167. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Computer simulation of etomidate action on the thalamocortical system revealed that GABAergic tonic inhibition, as compared to phasic inhibition, had greater depressant effects on cerebral cortical neuronal function. Furthermore, GABAergic anesthetic action in the thalamus alone does not likely explain how etomidate produces unconsciousness.

A Novel Process for Introducing a New Intraoperative Program: A Multidisciplinary Paradigm for Mitigating Hazards and Improving Patient Safety (Special Article)
Anesth Analg 2009 108: 202-210. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The development and introduction of a novel comprehensive multidisciplinary process that includes in situ simulation allows clinicians to proactively identify hazards and design safe-care systems. Anesthesiologists can play a pivotal role in improving clinical safety by leading changes in improving teamwork, creating a protocol for delivery of therapy, and changing the system before exposing patients to unnecessary and preventable hazards. With the novel process described in this paper, we have been able to implement a new intraoperative program that proactively identified potential hazards.

The Effect of Endothelin-1 on Alveolar Fluid Clearance and Pulmonary Edema Formation in the Rat
Anesth Analg 2009 108: 225-231. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This study shows that endothelin-1 (ET-1) inhibitis alveolar fluid clearance in anesthetized rats and in the isolated, ventilated, perfused rat lung by inhibition of amiloride-sensitive epithelial Na+ channels. This effect is mediated by the endothelin-B-receptor, and, in addition to increasing capillary pressure, contributes to pulmonary edema formation in situations when ET-1 expression is incresaed, e.g., in acute respiratory distress syndrome and at high-altitude.

Acute Interstitial Pneumonia–Hamman-Rich Syndrome: Clinical Characteristics and Diagnostic and Therapeutic Considerations
Anesth Analg 2009 108: 232-237. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This retrospective study suggests that acute interstitial pneumonia is a rapidly progressive disease frequently leading to respiratory failure and mechanical ventilation. We propose that transbronchial lung biopsy may be a logical first diagnostic step, to be followed by an open lung biopsy, if necessary.

Etomidate Infusion in the Critical Care Setting for Suppressing the Acute Phase of Cushing’s Syndrome (Case Report)
Anesth Analg 2009 108: 238-239. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Although prolonged sedation with etomidate is contraindicated due to the endocrine complications of the drug, our young, female patient with typical Cushing's syndrome did not respond to other therapeutic methods. Etomidate infusion was successfully used to suppress the hypercortisolic state. This may be an option for other patients with Cushing's syndrome.

Airway Scope and StyletScope for Tracheal Intubation in a Simulated Difficult Airway
Anesth Analg 2009 108: 273-279. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Direct laryngoscopy is difficult in patients whose cervical spine is immobilized by a rigid collar. The Airway Scope(R) and StyletScope(R) are laryngoscopes designed to facilitate difficult tracheal intubation. Both offer high success rates in these patients, however, Airway Scope is faster and less likely to cause esophageal intubation.

Postischemic Brain Injury Is Attenuated in Mice Lacking the β₂-Adrenergic Receptor
Anesth Analg 2009 108: 280-287. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Brain injury is reduced and neurological outcome improved after middle cerebral artery occlusion in mice lacking the {beta}2AR or in wild type mice pretreated with a selective {beta}2AR antagonist. This is consistent with a shift away from prosurvival signaling to prodeath signaling in the presence of {beta}2AR activation in cerebral ischemia.

Cardiovascular Safety of the Cyclooxygenase-2 Selective Inhibitors Parecoxib and Valdecoxib in the Postoperative Setting: An Analysis of Integrated Data
Anesth Analg 2009 108: 299-307. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Parecoxib and valdecoxib were not found to increase the risk of cardiovascular adverse events after noncardiac surgery, suggesting that the increased risk of cardiovascular thromboembolic events associated with parecoxib and valdecoxib after cardiac surgery with cardiopulmonary bypass cannot be generalized to patients undergoing noncardiac surgery.

The Effects of Smoking Status on Opioid Tapering Among Patients with Chronic Pain
Anesth Analg 2009 108: 308-315. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Clinical observations suggest that there is an association between chronic opioid use and smoking which may affect the ability of smokers with chronic pain to eliminate the use of opioids. Despite an increased frequency of baseline opioid use, smoking did not affect the success of opioid tapering.

The Effects of Local Anesthetic Concentration and Dose on Continuous Infraclavicular Nerve Blocks: A Multicenter, Randomized, Observer-Masked, Controlled Study
Anesth Analg 2009 108: 345-350. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Patients with a continuous infraclavicular nerve block given a 0.4% ropivacaine infusion at 4 mL/h experienced an insensate limb three times more often than those given an equal basal dose, but as a 0.2% concentration at 8 mL/h. This is the opposite of the relationship previously reported for continuous popliteal-sciatic nerve blocks. The interaction between local anesthetic concentration and volume is thus complex and varies among catheter locations.

An Evaluation of the Epidural Catheter Position by Epidural Nerve Stimulation in Conjunction with Continuous Epidural Analgesia in Adult Surgical Patients
Anesth Analg 2009 108: 351-358. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The epidural nerve stimulation test, which has been described as a simple and reliable way to confirm epidural catheter position, was associated with technical difficulties and interpretation problems. The role of the repeated use of the epidural stimulation test in improving the quality of analgesia in patients undergoing postoperative continuous epidural analgesia remains undetermined.

The Influence of Arm Abduction on the Anatomic Relations of Infraclavicular Brachial Plexus: An Ultrasound Study (Brief Report)
Anesth Analg 2009 108: 364-366. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Arm abduction reduces the depth of the brachial plexus at the infraclavicular level but does not have a marked influence on the position of the brachial plexus relative to the coracoid process or the pleura. Ultrasound examination may under-estimate the skin-to-plexus distance due to the transducer pressure on the skin and compression of the underlying tissues.

Tramadol as an Adjuvant to Lidocaine for Axillary Brachial Plexus Block (Brief Report)
Anesth Analg 2009 108: 367-370. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This study confirms the benefit of perineural use of tramadol. The prolongation of blocks and postoperative analgesia are dose-dependent. However, the delay of onset of the block with high-dose tramadol could limit its routine use.
