The Effects of Argatroban on Thrombin Generation and Hemostatic Activation In Vitro (Case Report)
Anesth Analg 2004 99: 1283-1289. [Abstract] [Full Text]  

IMPLICATIONS: Argatroban can effectively reduce thrombin generation and prolong activated clotting in vitro. On the basis of its rapid binding to thrombin and its relatively short elimination half-life, argatroban may prove to be a useful adjunct for treating heparin resistance during cardiac surgery.

A Novel Thrombelastograph® Tissue Factor/Kaolin Assay of Activated Clotting Times for Monitoring Heparin Anticoagulation During Cardiopulmonary Bypass (Case Report)
Anesth Analg 2004 99: 1290-1294. [Abstract] [Full Text]  

IMPLICATIONS: This study evaluates the thrombelastograph as a new assay of blood clotting times; it is activated by the addition of tissue clotting factor and kaolin and used to monitor heparin anticoagulation during cardiopulmonary bypass. The thrombelastograph assay correlates with standard assays, is faster, is less sensitive to hemodilution, and can provide more information.

S(+)-Ketamine as an Analgesic Adjunct Reduces Opioid Consumption After Cardiac Surgery (Case Report)
Anesth Analg 2004 99: 1295-1301. [Abstract] [Full Text]  

IMPLICATIONS: This is the first placebo-controlled study to evaluate the efficacy and feasibility of S(+)-ketamine as a complementary analgesic to opioid after sternotomy in cardiac surgery patients. A small-dose S(+)-ketamine bolus followed by a continuous infusion for 48 h decreased cumulative opioid consumption and resulted in improved patient satisfaction with pain management. However, a few patients developed transient hallucinations.

The Impact of Isoflurane During Simulated Ischemia/Reoxygenation on Intracellular Calcium, Contractile Function, and Arrhythmia in Ventricular Myocytes (Case Report)
Anesth Analg 2004 99: 1302-1307. [Abstract] [Full Text]  

IMPLICATIONS: Isoflurane, a volatile anesthetic, administered during ischemia/reoxygenation, aggravated functional impairment in heart muscle cells. These alterations were probably caused by interference with intracellular Ca2+ handling proteins and by generation of oxygen radicals. Cardioprotection by isoflurane when given before ischemia should be reevaluated in situations of continuing ischemia and subsequent reperfusion.

Preconditioning by Isoflurane Is Mediated by Reactive Oxygen Species Generated from Mitochondrial Electron Transport Chain Complex III (Case Report)
Anesth Analg 2004 99: 1308-1315. [Abstract] [Full Text]  

IMPLICATIONS: The electron transport chain complex III inhibitor myxothiazol, but not the complex I inhibitor diphenyleneiodonium, abolished isoflurane-induced protection against ischemia-reperfusion injury and reactive oxygen species production in rabbits. Reactive oxygen species generated from electron transport chain complex III act in the signal transduction process mediating preconditioning by isoflurane in vivo.

Protein Kinase C Inhibitors Produce Mitochondrial Flavoprotein Oxidation in Cardiac Myocytes (Case Report)
Anesth Analg 2004 99: 1316-1322. [Abstract] [Full Text]  

IMPLICATIONS: Inhibition of protein kinase C (PKC) blocks ischemic and anesthetic preconditioning of the myocardium. We observed that PKC inhibition produces intense oxidation of mitochondria by a pathway involving inositol triphosphate. This may indicate that PKC modulates adenosine triphosphate-sensitive K channels to prevent injurious mitochondrial oxidation.

The Effect of Apolipoprotein E Genotype on Neuron Specific Enolase and S-100ß Levels After Cardiac Surgery (Brief Report)
Anesth Analg 2004 99: 1323-1325. [Abstract] [Full Text]  

IMPLICATIONS: Two blood tests thought to be biomarkers for brain injury were found to be increased after cardiac surgery with larger increases in patients with the apolipoprotein {epsilon}4 gene, a gene linked to Alzheimer's disease. There may be genetic differences in susceptibility to neurologic problems after surgery.

A Perioperative Echocardiographic Reporting and Recording System (Technical Communication)
Anesth Analg 2004 99: 1326-1329. [Abstract] [Full Text]  

IMPLICATIONS: The development of inexpensive digital video transcoders and the incorporation of highly efficient video capture, compression, and streaming technology into the Windows(R) computer operating system has simplified the task of implementing a high-fidelity, real-time, digital, echocardiographic recording system. An application that uses these technologies and runs on a notebook computer is described.

Is Muscle Relaxant Necessary for Cardiac Surgery? (Technical Communication)
Anesth Analg 2004 99: 1330-1333. [Abstract] [Full Text]  

IMPLICATIONS: Residual paralysis as a result of repetitive doses or continuous administration of muscle relaxants is counterproductive for fast-track cardiac surgery which aims for early postoperative extubation and quick recovery. Perioperative patient movement, unwanted diaphragmatic contractions, difficult surgical conditions, and residual paralysis were prevented in 87 patients undergoing cardiac surgery by injecting a single dose of either atracurium or cisatracurium during induction of anesthesia. This practice has no negative impact on surgery and allows early and safe extubation of the trachea.

The Effects of Propofol, Small-Dose Isoflurane, and Nitrous Oxide on Cortical Somatosensory Evoked Potential and Bispectral Index Monitoring in Adolescents Undergoing Spinal Fusion
Anesth Analg 2004 99: 1334-1340. [Abstract] [Full Text]  

IMPLICATIONS: In adolescent patients undergoing spinal fusion, propofol better preserves cortical somatosensory evoked potential amplitude measurement and provides a deeper level of hypnosis as measured by bispectral index values than combinations of small-dose isoflurane-N2O or small-dose isoflurane alone.

Fibrinogen in Children Undergoing Cardiac Surgery: Is It Effective?
Anesth Analg 2004 99: 1341-1346. [Abstract] [Full Text]  

IMPLICATIONS: Fibrinogen appears to be dysfunctional in children <12 mo old with congenital heart disease based on evidence from modified thromboelastography. This may help explain the benefits of transfusing cryoprecipitate to infants after cardiopulmonary bypass and may limit the use of modified thromboelastography in transfusion algorithms for infants after cardiac surgery.

The Pharmacokinetics of the Intravenous Formulation of Fentanyl Citrate Administered Orally in Children Undergoing General Anesthesia
Anesth Analg 2004 99: 1347-1351. [Abstract] [Full Text]  

IMPLICATIONS: In this pilot study of 10 children undergoing general anesthesia, we found pharmacokinetic variables and plasma concentrations with the IV formulation of fentanyl given by mouth to be similar to those described for oral transmucosal fentanyl. Further studies of efficacy and safety are required before this method of fentanyl administration can be safely recommended.

The Efficacy of the Arrow Staple Device for Securing Central Venous Catheters to Human Skin
Anesth Analg 2004 99: 1436-1439. [Abstract] [Full Text]  

IMPLICATIONS: Suturing central venous catheters to the skin exposes health care workers to unnecessary risks of needlestick injury. We compared the efficacy of an alternative attachment method using staples with the widely accepted suture method. Determining the anchoring strength of staples is important because there may be substantial risk and difficulty reinserting inadvertently dislodged catheters.

Intrathecal Morphine, but Not Buprenorphine or Pentazocine, Can Induce Spastic Paraparesis After a Noninjurious Interval of Spinal Cord Ischemia in the Rat (Brief Report)
Anesth Analg 2004 99: 1528-1531. [Abstract] [Full Text]  

IMPLICATION: The present study shows that neither intrathecal pentazocine nor intrathecal buprenorphine can increase spasticity of hindlimbs after a noninjurious interval of spinal cord ischemia in rats. These results indicate that the effect of various opioids on motor function after a noninjurious interval of spinal cord ischemia might be opioid-specific.

A Multicenter Randomized Controlled Trial Comparing Patient-Controlled Epidural with Intravenous Analgesia for Pain Relief in Labor
Anesth Analg 2004 99: 1532-1538. [Abstract] [Full Text]  

IMPLICATIONS: Two-hundred forty-two healthy, term, nulliparous patients in spontaneous labor were randomized to receive either patient-controlled IV or patient-controlled epidural labor analgesia. No difference in the incidence of cesarean delivery was observed between groups. The data support the hypothesis that epidural analgesia does not increase the incidence of cesarean delivery compared with IV analgesia.

Successful Removal of a Knotted Fascia Iliaca Catheter: Principles of Patient Positioning for Peripheral Nerve Catheter Extraction (Case Report)
Anesth Analg 2004 99: 1550-1552. [Abstract] [Full Text]  

IMPLICATIONS: We describe successful removal of a knotted fascia iliaca catheter. The principles for removal of knotted or broken peripheral catheters are not well known and may differ from those for spinal or epidural catheters. Altering patient positioning to minimize pressure and tension on the soft tissues surrounding the catheter may facilitate catheter removal.
