Postcardiac Surgery Complications: Association of Acute Renal Dysfunction and Atrial Fibrillation
Anesth Analg 2003 96: 637-643. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We found an independent association between new-onset atrial fibrillation and postoperative creatinine increase that is influenced by age. The degree to which atrial fibrillation is associated with postoperative creatinine increase diminishes with advancing age. This interaction suggests that a common etiology for these two complications may be more important in younger patients.

Comparison of Alpha-Stat and pH-Stat Cardiopulmonary Bypass in Relation to Jugular Venous Oxygen Saturation and Cerebral Glucose-Oxygen Utilization
Anesth Analg 2003 96: 644-650. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: A prospective, randomized study in 52 patients during cardiopulmonary bypass revealed that pH-stat increased jugular venous oxygen saturation and decreased arteriovenous oxygen-glucose differences. There was no difference in the incidence of jugular venous desaturation. These findings suggest an increased cerebral blood flow with no protection against jugular venous desaturation during pH-stat.

Changes in Cerebral Microcirculation During and After Abdominal Aortic Cross-Clamping in Rabbits: The Role of Thromboxane A₂ Receptor
Anesth Analg 2003 96: 651-656. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Abdominal aortic unclamping after a 20-min clamp caused an initial dilation followed by a sustained constriction of pial arterioles. Seratrodast, a thromboxane A2 receptor antagonist, attenuated the vasoconstriction suggesting that it is at least partly mediated by thromboxane A2 washed out from the region rendered ischemic by clamping.

Dexmedetomidine Decreases Perioperative Myocardial Lactate Release in Dogs
Anesth Analg 2003 96: 657-664. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Dexmedetomidine decreases plasma catecholamines and heart rate during emergence from anesthesia. In dogs with a coronary stenosis, these sympatholytic effects decrease myocardial lactate release and, therefore, minimize emergence-related myocardial ischemia.

Mexiletine Differentially Modulates Vasorelaxation Mediated by Adenosine Triphosphate-Sensitive K⁺ Channels in Aortas from Normotensive and Hypertensive Rats
Anesth Analg 2003 96: 673-679. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Mexiletine induces augmentation of vasodilation mediated by adenosine triphosphate (ATP)-sensitive K+ channels activated by the opener as well as a nitric oxide donor in normotensive, but not hypertensive, rat aortas, partly by the soluble guanylate cyclase-independent action of nitric oxide on ATP-sensitive K+ channels of vascular smooth muscle cells.

Patient-Controlled Epidural Analgesia in Children: Can They Do It?
Anesth Analg 2003 96: 686-691. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: A descriptive analysis of prospectively recorded data in 132 children receiving patient-controlled epidural analgesia for postoperative pain relief demonstrates satisfactory analgesia without serious toxicity or side effects in children as young as 5 yr. This modality should be considered as another strategy in pediatric postoperative pain management.

Single-Lung Ventilation with a Cuffed Endotracheal Tube in a Child with a Left Mainstem Bronchus Disruption (Case Report)
Anesth Analg 2003 96: 696-697. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS:We report a case of management of ventilation during operative repair of a traumatic left mainstem bronchial disruption in a pediatric patient. With the use of a conventional cuffed endotracheal tube, with the cuff partially in the right mainstem bronchus and partially in the trachea, we successfully managed the case with single-lung ventilation.

A Comparison of Airway Responses During Desflurane and Sevoflurane Administration via a Laryngeal Mask Airway for Maintenance of Anesthesia (Brief Report)
Anesth Analg 2003 96: 701-705. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Although sevoflurane is less pungent than desflurane at larger concentrations, neither anesthetic seems to irritate the airway when administered at the smaller concentrations often used during maintenance of anesthesia. Both anesthetics may be delivered effectively via a laryngeal mask airway, with minimal evidence of airway irritation.

GABA_A Receptor Blockade Antagonizes the Immobilizing Action of Propofol but Not Ketamine or Isoflurane in a Dose-Related Manner
Anesth Analg 2003 96: 706-712. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: IV picrotoxin and gabazine antagonized the immobilizing action of propofol in a dose-related manner, whereas antagonism of the immobilizing action of ketamine and isoflurane was similar, smaller than for propofol, and not dose-related. These results are consistent with a role for {gamma}-amino-n-butyric acid subtype A receptors in mediating propofol anesthesia but not ketamine or isoflurane anesthesia.

The Effect of Propofol on the Interaction of Platelets with Leukocytes and Erythrocytes in Surgical Patients
Anesth Analg 2003 96: 713-719. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS:In vitro experiments have shown that propofol inhibits platelet aggregation and increases nitric oxide production. This study shows that doses habitually used to induce or maintain anesthesia also have these effects. These findings have potential applications for patients at increased risk for bleeding and may partly explain the hypotensive effect of propofol.

Changes in Consciousness, Conceptual Memory, and Quantitative Electroencephalographical Measures During Recovery from Sevoflurane- and Remifentanil-Based Anesthesia
Anesth Analg 2003 96: 720-725. [Abstract] [Full Text] [PDF] [Appendix]  [Request Permissions]  

IMPLICATIONS: During the recovery phase from a remifentanil-based anesthetic, the bispectral index is not reliably predictive of the depth of consciousness, because of suppression ratio artifacts. Entropy measures of the electroencephalogram show promise, but there is still no gold standard to estimate anesthetic depth.

Modulation of Remifentanil-Induced Analgesia, Hyperalgesia, and Tolerance by Small-Dose Ketamine in Humans
Anesth Analg 2003 96: 726-732. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Coadministration of ketamine and morphine for pain relief is still controversial. Our experimental pain study with volunteers showed that ketamine enhances opioid analgesia without increasing sedation and reduces respiratory depression. Opioid-induced hyperalgesia and tolerance were not affected by ketamine and depended on the type of nociceptive stimulus. This may explain the conflicting results on opioid tolerance in previous studies.

Modulation of Myofilament Ca²⁺ Sensitivity by - and -Opioid Agonists in Intact Guinea Pig Hearts
Anesth Analg 2003 96: 733-739. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Our results indicate that {delta}- and {kappa}-opioid agonists enhance myofilament Ca2+ sensitivity despite decreasing available intracellular Ca2+ concentrations in intact isolated guinea pig beating hearts, and these effects are mediated by {delta}- and {kappa}-opioid receptor stimulation.

The Postoperative Effects of Halothane Versus Isoflurane on Hepatic Artery and Portal Vein Blood Flow in Humans
Anesth Analg 2003 96: 740-745. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Volatile anesthetics may alter liver circulation with serious adverse effects. Using implanted pulsed Doppler probes in six anesthetized patients, we showed that halothane acted mainly as a vasoconstrictor of the liver vascular bed, whereas isoflurane was a vasodilator, confirming the beneficial effect of isoflurane on liver oxygen supply.

Gamma-Aminobutyric Acid Neuropharmacological Investigations on Narcosis Produced by Nitrogen, Argon, or Nitrous Oxide
Anesth Analg 2003 96: 746-749. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We studied the effects in the rat of {gamma}-aminobutyric acid (GABA) receptor antagonists on narcosis induced by nitrogen and argon that act only at high pressures. Our results show that the GABA A receptor may play a significant role, suggesting that some mechanisms might be similar to those of clinical inhaled anesthetics.

The Effect of Vecuronium Is Enhanced by a Large Rather than a Modest Dose of Gentamicin as Compared with No Preoperative Gentamicin
Anesth Analg 2003 96: 750-754. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We demonstrated that the neuromuscular relaxant effect of vecuronium is enhanced by a large (4 mg/kg) rather than a modest (1.2 mg/kg) dose of gentamicin as compared with no gentamicin given before surgery.

Carbon Monoxide Production from Sevoflurane Breakdown: Modeling of Exposures Under Clinical Conditions
Anesth Analg 2003 96: 757-764. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Sevoflurane breakdown in desiccated absorbents is expected to result in only mild carbon monoxide (CO) exposure. Completely dry absorbent and high minute ventilation rates may degrade sevoflurane to extremely large CO concentrations. Serious CO poisoning or spontaneous ignition of flammable gases within the breathing circuit are possible in extreme circumstances.

Intravenous Droperidol Causes a Reduction in the Bispectral Index in Propofol-Sedated Patients During Spinal Anesthesia
Anesth Analg 2003 96: 765-768. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: An antiemetic dose of IV droperidol causes a decrease in the bispectral index in patients sedated with propofol during spinal anesthesia. We conclude that droperidol may enhance the hypnotic effect of propofol.

Continuous Intrathecal Clonidine and Tizanidine in Conscious Dogs: Analgesic and Hemodynamic Effects
Anesth Analg 2003 96: 776-782. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Clonidine is an effective spinal analgesic, but it is dose-limited by cardiovascular side effects. We compared the analgesic properties and side effects of clonidine with those of a similar drug, tizanidine. Continuous spinal infusion of tizanidine produced similar analgesia as clonidine, but with fewer adverse effects on blood pressure and heart rate.

The Effects of Intrathecal Tramadol on Spinal Somatosensory-Evoked Potentials and Motor-Evoked Responses in Rats
Anesth Analg 2003 96: 783-788. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Spinal somatosensory-evoked potentials and evoked compound muscle action potential were used to evaluate the effects of intrathecal tramadol on sensory and motor neural conduction. Intrathecal tramadol dose-dependently reduced the amplitude and delayed the latency of both spinal somatosensory-evoked potentials and compound muscle action potential. These results indicate that tramadol exerts a dose-related central neural blockade.

Inclusion of Turnover Time Does Not Influence Identification of Surgical Services that Over- and Underutilize Allocated Block Time
Anesth Analg 2003 96: 813-818. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Turnover time is difficult to determine from existing operating room information systems. This study determined the use of block time with and without turnover time for each surgical service in a large academic hospital. Turnover time did not change identification of surgical services that over- (one service) or underused (three services) allocated block time.

Nerve Gas Terrorism: A Grim Challenge to Anesthesiologists (Special Article)
Anesth Analg 2003 96: 819-825. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The 1995 Tokyo subway strike proved nerve gas to be a fearsome terrorist weapon of mass destruction. Because the clear liquid is easily hidden until released, rescuers must aid nonbreathing casualties near instantly. Anesthesiologists are uniquely qualified to train these rescue squads and to manage nerve gas victims in the hospital.

Noninvasive Estimation of Cerebral Perfusion Pressure and Zero Flow Pressure in Healthy Volunteers: The Effects of Changes in End-Tidal Carbon Dioxide
Anesth Analg 2003 96: 847-851. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Increasing end-tidal CO2 increases the estimated cerebral perfusion pressure and vice versa. These results are opposite to those expected from the known effects of CO2 on intracranial pressure. Thus, we support the suggestion that, in the absence of intracranial hypertension, vascular tone remains a major determinant of effective downstream pressure and cerebral perfusion.

Intrathecal Fentanyl, Sufentanil, or Placebo Combined with Hyperbaric Mepivacaine 2% for Parturients Undergoing Elective Cesarean Delivery
Anesth Analg 2003 96: 852-858. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Sensory, motor, and analgesic block characteristics of the local anesthetic mepivacaine alone or combined with intrathecal opioids were studied in parturients undergoing elective cesarean delivery in a randomized, double-blinded clinical trial. Mepivacaine was found to be an acceptable local anesthetic for spinal anesthesia in parturients undergoing cesarean delivery. In combination with sufentanil 5 {micro}g, complete and effective analgesia were significantly prolonged.

An Evaluation of the Supraclavicular Plumb-Bob Technique for Brachial Plexus Block by Magnetic Resonance Imaging
Anesth Analg 2003 96: 862-867. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In magnetic resonance images of volunteers, simulated needle passes with the "plumb-bob" approach to the supraclavicular brachial plexus block were analyzed for precision and risk profile. To avoid needle contact with the lung, the subclavian vein, and the subclavian artery, our results suggest a change in the method's initial needle direction.

Infragluteal-Parabiceps Sciatic Nerve Block: An Evaluation of a Novel Approach Using a Single-Injection Technique
Anesth Analg 2003 96: 868-873. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Sciatic nerve block using the infragluteal-parabiceps approach produces sensory loss and motor paralysis after a single 0.4 mL/kg injection of levobupivacaine 0.625% with epinephrine (1:200,000) in >90% of patients. The approach is reliable, uses consistent soft-tissue landmarks, is not typically painful, and does not produce significant complications.

The Effect of Spinal Bupivacaine in Combination with Either Epidural Clonidine and/or 0.5% Bupivacaine Administered at the Incision Site on Postoperative Outcome in Patients Undergoing Lumbar Laminectomy
Anesth Analg 2003 96: 874-880. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Spinal anesthesia with supplemental epidural clonidine in combination with incision site subcutaneous bupivacaine was evaluated both intra- and postoperatively and compared with spinal anesthesia alone for lower lumbar spine procedures. Both epidural clonidine and subcutaneous incisional bupivacaine, added to spinal anesthesia for lumbar spine surgery, improves pain relief and reduces the need for postoperative opioids with their associated side effects.

A Comparison of Hyperbaric 1% and 3% Solutions of Small-Dose Lidocaine in Spinal Anesthesia
Anesth Analg 2003 96: 881-884. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: When the dose of lidocaine was kept constant at 30 mg, hyperbaric 1% lidocaine solution resulted in shorter times for recovery from motor block and to urination than did hyperbaric 3% lidocaine solution. Levels of sensory block were similar. Therefore, the more dilute lidocaine for spinal anesthesia may be suitable for day-care surgery and short duration surgery.
