The Effect of Dilution on Plasma Coagulation Kinetics Determined by Thrombelastography Is Dependent on Antithrombin Activity and Mode of Activation (Case Report)
Anesth Analg 2004 99: 1587-1592. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Hemodilution-associated hypercoagulability is of clinical interest, given the morbidity and mortality associated with perioperative thrombophilia. We determined that decreased antithrombin activity is responsible for accelerated clot initiation via thrombelastography with in vitro plasma-based experiments. Celite activation of plasma resulted in a linear relationship between degree of dilution and thrombelastographic variables.

The Effect of Hemopure® on Coagulation in Clinically Relevant Concentrations (Case Report)
Anesth Analg 2004 99: 1593-1597. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Hemopure(R), a polymerized bovine hemoglobin used as a blood substitute, might interfere with coagulation. At clinically relevant in vitro dilutions of whole blood, the effects of Hemopure(R) on whole-blood coagulation as measured by the thrombelastograph were not significantly different from those of the carrier substance, lactated Ringer's solution.

The Response to Activated Protein C After Cardiopulmonary Bypass: Impact of Factor V Leiden (Case Report)
Anesth Analg 2004 99: 1598-1603. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Patients without factor V Leiden (FVL) have increased sensitivity to the activated protein C after cardiac surgery, whereas FVL carriers do not. These data provide mechanistic support for previous speculations that FVL subjects are at increased postoperative thrombotic risk relative to noncarriers.

Fenoldopam Mesylate and Renal Function in Patients Undergoing Liver Transplantation: A Randomized, Controlled Pilot Trial (Case Report)
Anesth Analg 2004 99: 1604-1609. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We evaluated renal function comparing fenoldopam versus dopamine in liver transplantation recipients. In the fenoldopam-treated group, serum creatinine and BUN improved. There were more "interventions" of furosemide to maintain urine output >1 mL {middle dot} kg-1 {middle dot} h-1 in the dopamine group.

The Effects of Halothane, Isoflurane, and Sevoflurane on Ca²⁺ Current and Transient Outward K⁺ Current in Subendocardial and Subepicardial Myocytes from the Rat Left Ventricle (Case Report)
Anesth Analg 2004 99: 1615-1622. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Halothane, isoflurane, and sevoflurane reduce action potential duration (APD) by virtue of inhibitory effects on membrane currents, principally the calcium current. The differential effects of anesthetics on APD in the subepicardium and subendocardium appear to be due to their inhibitory action on the transient outward K+ current.

Transfusion-Related Acute Lung Injury (Brief Report)
Anesth Analg 2004 99: 1623-1624. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Transfusion may rarely cause acute lung injury. Diagnosis is difficult because there is no single test for the condition. Diagnosis and management are described. Earlier recognition may lead to earlier diagnosis, treatment, and prevention.

The Anterior Jugular Venous System: Variability and Clinical Impact (Case Report)
Anesth Analg 2004 99: 1625-1629. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The anterior jugular venous system provides an important collateral venous network with the subclavian and deep jugular veins, especially in unilateral occlusion of an innominate vein. In such cases, central venous catheters may be correctly placed via the anterior jugular venous system. However, central venous catheters malpositioned in the anterior jugular vein can increase the risk for complications and should be removed.

The Development and Validation of a Risk Score to Predict the Probability of Postoperative Vomiting in Pediatric Patients
Anesth Analg 2004 99: 1630-1637. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The incidence of postoperative vomiting might be predicted using duration of surgery >=30 min, age >=3 yr, strabismus surgery, and a positive history of postoperative vomiting/postoperative nausea and vomiting in the children or in their relatives. The predicted incidence of postoperative vomiting is 9%, 10%, 30%, 55%, and 70% for 0-4 of these risk factors present.

Anesthetic Concerns for Robot-Assisted Laparoscopy in an Infant (Case Report)
Anesth Analg 2004 99: 1665-1667. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The robotic surgical system for pediatric laparoscopy severely limits the anesthesiologist's access to the patient and requires advance preparation to ensure patient safety. We present the anesthetic management of the first successful robot-assisted laparoscopic Kasai procedure in an infant.

Postoperative Confusion Increases in Elderly Long-Term Benzodiazepine Users
Anesth Analg 2004 99: 1674-1678. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Some elderly patients are preoperatively treated with benzodiazepines for anxiety, insomnia, and depression. Although preoperative use of benzodiazepines is one of the risk factors for postoperative confusion, the relationship between postoperative confusion and preoperative psychiatric symptoms or duration of benzodiazepine exposure is unclear.

The Postoperative Blood-Sparing Efficacy of Oral Versus Intravenous Tranexamic Acid After Total Knee Replacement
Anesth Analg 2004 99: 1679-1683. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: To decrease complications related to blood transfusions, pharmacological manipulation of the clotting system may be performed. However, such strategies must be safe, reliable, and easy to administer. This study demonstrates that the blood-sparing efficacy of oral tranexamic acid is similar to that of IV tranexamic acid.

The Effect of Epidural Bupivacaine on Induction and Maintenance Doses of Propofol (Evaluated by Bispectral Index) and Maintenance Doses of Fentanyl and Vecuronium
Anesth Analg 2004 99: 1684-1688. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Epidural local anesthetics reduce the requirement of hypnotics, analgesics, and muscle relaxants. However, no study has evaluated the effect of local anesthetics on all three components of balanced anesthesia, i.e., hypnosis, analgesia, and muscle relaxation, in the clinical setting. We observed that epidural bupivacaine significantly reduces the requirement of all three during general anesthesia.

The Inotropic and Lusitropic Effects of Ketamine in Isolated Human Atrial Myocardium: The Effect of Adrenoceptor Blockade
Anesth Analg 2004 99: 1689-1695. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In isolated human myocardium, racemic ketamine induced a moderate positive inotropic effect but a profound direct negative inotropic effect in the presence of ß-adrenoceptor blockade. Furthermore, ketamine hastened relaxation through stimulation of ß-adrenoceptor. This should be interpreted with the known various physiopathologic states and treatments interfering with {alpha}- and ß-adrenoceptors.

The Hemodynamic Effects of Ephedrine on the Onset Time of Rocuronium in Pigs
Anesth Analg 2004 99: 1703-1707. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In an animal study, the effect of ephedrine on onset time, cardiac index, and muscle blood flow was determined after administration of thiopental. A correlation between onset time of muscle relaxants and hemodynamic variables is discussed. Our results demonstrated that ephedrine did not shorten onset time of rocuronium in healthy pigs.

Apoptosis Is Not Enhanced in Primary Mixed Neuronal/Glial Cultures Protected by Isoflurane AgainstN-Methyl-D-Aspartate Excitotoxicity
Anesth Analg 2004 99: 1708-1714. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Isoflurane inhibition of N-methyl-D-aspartate-induced necrotic cell death, evaluated in mixed neuronal/glial cell cultures, did not result in caspase-3-mediated apoptotic cell death. Our in vitro results failed to support the hypothesis that cells protected by isoflurane neuroprotection later deteriorate into an apoptotic state.

Potent Activation of the Human Tandem Pore Domain K Channel TRESK with Clinical Concentrations of Volatile Anesthetics
Anesth Analg 2004 99: 1715-1722. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Enhancement of background K channel currents by volatile anesthetics may contribute to neuronal depression during anesthesia. Currents passed by a newly discovered human background K channel, TWIK-related spinal cord K channel, are strongly enhanced by volatile anesthetics in the clinical range, suggesting a role for it in volatile anesthetic mechanisms.

Measuring Depth of Sedation with Auditory Evoked Potentials During Controlled Infusion of Propofol and Remifentanil in Healthy Volunteers
Anesth Analg 2004 99: 1728-1736. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Acoustic stimuli induce distinct changes in the electroencephalogram (EEG). We found that one component of these EEG modifications can be used to monitor the targeted light levels of sedation in critically ill patients nearly continuously, independent of adding remifentanil to a propofol-based sedation regime.

A Comparison of Postoperative Pain Control in Patients After Right Lobe Donor Hepatectomy and Major Hepatic Resection for Tumor
Anesth Analg 2004 99: 1747-1752. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Patients who underwent right lobe donor hepatectomy (RLDH) experienced more postoperative pain as compared with patients after major hepatic resection for tumor. This may be partially explained by the longer surgical duration observed in the RLDH group. Better perioperative teaching for patient-controlled epidural analgesia use may improve early postoperative pain control in RLDH patients.

The Intravenous Ketamine Test: A Predictive Response Tool for Oral Dextromethorphan Treatment in Neuropathic Pain
Anesth Analg 2004 99: 1753-1759. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In this study, an IV infusion of ketamine, a parenteral N-methyl-D-aspartate receptor antagonist, was found to predict the analgesic response to an oral treatment regimen of dextromethorphan, an oral N-methyl-D-aspartate antagonist, in 84% of patients with neuropathic pain. A fine-tuned IV ketamine test may enhance patient care by saving time and conserving valuable resources.

Intrinsic Spinal Cord Catheter Placement: Implications of New Intractable Pain in a Patient with a Spinal Cord Injury (Case Report)
Anesth Analg 2004 99: 1763-1765. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: A case is presented of new intractable flank pain after intrathecal infusion system placement in a man with a T12 spinal cord injury. Pain after intrathecal infusion system placement was evaluated by magnetic resonance imaging and the catheter was found to be intraparenchymal. Increased vigilance is warranted when caring for paraplegic patients.

A Comparison of Changes in Cardiac Preload Variables During Graded Hypovolemia and Hypervolemia in Mechanically Ventilated Dogs
Anesth Analg 2004 99: 1780-1786. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We simultaneously monitored dynamic preload variables—such as systolic blood pressure variation, its down component, pulse pressure variation, stroke volume variation, and esophageal Doppler-derived corrected flow time—during induced hypovolemia and hypervolemia. The results demonstrated that these variables, with the exception of corrected flow time, are useful indicators of hypovolemia, but not of hypervolemia.

Ventricular Fibrillation Median Frequency May Not Be Useful for Monitoring During Cardiac Arrest Treated with Endothelin-1 or Epinephrine
Anesth Analg 2004 99: 1787-1793. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Median fibrillation frequency (MF) has been suggested as an online monitoring tool during resuscitation. In a pig model, during prolonged resuscitation, we compared the individual curves of MF, mean fibrillation amplitude, and coronary perfusion pressure and found that MF was not useful for monitoring resuscitation efforts.

A Novel Method to Assess Platelet Inhibition by Eptifibatide with Thrombelastograph®
Anesth Analg 2004 99: 1794-1799. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We examined a novel batroxobin-based activator for detecting platelet inhibition induced by eptifibatide on thrombelastography (TEG(R)). We concluded that batroxobin-modified TEG(R) was more sensitive than kaolin TEG(R) for detecting eptifibatide-induced platelet inhibition at clinical concentrations.

Hepatic Hydrothorax in the Absence of Ascites: Respiratory Failure in a Cirrhotic Patient (Case Report)
Anesth Analg 2004 99: 1803-1804. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Hydrothorax is a pleural space fluid accumulation. Most pleural effusions are rarely observed. Although unusual, these effusions associated with hepatic cirrhosis and ascites have been well described. However, the case we present here showed no clinical signs of ascites before surgery. Therefore, the patient developed a right-sided hydrothorax as a result of residual motor blockade during anesthesia recovery.

Is Intrathecal Magnesium Sulfate Safe and Protective Against Ischemic Spinal Cord Injury in Rabbits?
Anesth Analg 2004 99: 1805-1812. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Intrathecal administration of magnesium sulfate has a risk of neurotoxicity and shows no evidence of protective effects against ischemic spinal cord injury. Although the intrathecal use of magnesium sulfate has been reported in humans, further evaluations of its safety are warranted.

Acute Adrenal Insufficiency After Large-Dose Glucocorticoids for Spinal Cord Injury (Case Report)
Anesth Analg 2004 99: 1813-1814. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We describe a patient who developed adrenal insufficiency (AI) after glucocorticoid therapy for spinal cord injury. Their temporal association and the exclusion of other possible etiologies led us to postulate that AI was a complication of the glucocorticoids. Clinicians should, therefore, consider AI in patients with SCI receiving glucocorticoids.

Iatrogenic Arteriovenous Fistula During Lumbar Microdiscectomy (Case Report)
Anesth Analg 2004 99: 1815-1817. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Iatrogenic vascular injuries after lumbar disk surgery are rare but potentially life threatening. Such injuries may perioperatively present in a diverse array of manifestations, and often the diagnosis is delayed or overlooked, which may increase morbidity and mortality. Early diagnosis and surgical repair of these vascular injuries can be life saving.

Using Heart Rate Variability to Stratify Risk of Obstetric Patients Undergoing Spinal Anesthesia
Anesth Analg 2004 99: 1818-1821. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The heart rate variability statistic peak point correlation dimension (PD2) successfully predicted hypotension within 20 min of spinal anesthesia in all 22 pregnant women undergoing cesarean delivery. If further research supports this finding, real-time electrocardiograph analysis of peak PD2 might prevent adverse circulatory events in these women.

Determining Minimum Alveolar Anesthetic Concentration of Halothane in Rats: The Effect of Incremental Change in Halothane Concentration and Number of Crossovers
Anesth Analg 2004 99: 1822-1828. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We determined the minimum alveolar anesthetic concentration (MAC) of halothane in rats by using the bracketing technique. The size of the incremental change in halothane affected the estimation of MAC. Increment size should be considered when MAC estimates are compared between studies or when the accuracy of MAC is assessed.

Paramedian Lumbar Epidural Catheter Insertion with Patients in the Sitting Position Is Equally Successful in the Flexed and Unflexed Spine
Anesth Analg 2004 99: 1829-1832. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Positioning for lumbar epidural block involves flexing the spine, which can be difficult and painful in patients with lower limb injury. With the paramedian approach, it was possible to perform the block in most sitting patients without flexing the spine. The median approach required spinal flexion in most patients.

Anesth Analg 2004 99: 1861-1863. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Hydrogen peroxide is used intraoperatively and perioperatively for the identification of fistula tracts. A venous oxygen embolism occurred in a 66-yr-old man after the intraoperative injection of 60 mL 3% hydrogen peroxide into an enterocutaneous fistula. The relevant aspects of the diagnosis and treatment of oxygen embolism are discussed.

Anesth Analg 2004 99: 1864-1866. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The incorrect assembly of a bladder irrigation system caused air to be pumped from an open drain through the resectoscope into the bladder, which led to a near fatal cardiac arrest caused by venous air embolism. Anesthesiologists and urologists should be aware of this potential complication.
