Acute Hemodynamic Collapse After Induction of General Anesthesia for Emergent Pulmonary Embolectomy
Anesth Analg 2006 102: 1311-1315. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: In patients undergoing pulmonary embolectomy, severe hypotension after anesthesia induction, which requires emergent institution of cardiopulmonary bypass, occurs frequently (19%) and is unpredictable. Therefore, we recommend preparing and draping patients before induction of general anesthesia for surgical pulmonary embolectomy.

Anesthetic Preconditioning with Sevoflurane Does Not Protect the Spinal Cord After an Ischemic-Reperfusion Injury in the Rat
Anesth Analg 2006 102: 1341-1347. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Paraplegia remains a devastating consequence of descending and thoracoabdominal aortic operations that have a period of obligate spinal cord ischemia. This research demonstrated no benefit of anesthetic preconditioning in attenuating this type of injury.

Inhibition of Glycogen Synthase Kinase Enhances Isoflurane-Induced Protection Against Myocardial Infarction During Early Reperfusion In Vivo
Anesth Analg 2006 102: 1348-1354. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Inhibition of the regulatory protein, glycogen synthase kinase, enhances protection against myocardial infarction by isoflurane administered immediately before and during early reperfusion after prolonged coronary artery occlusion via a mitochondrial permeability transition pore-dependent mechanism.

The Influence of B-Cell Lymphoma 2 Protein, an Antiapoptotic Regulator of Mitochondrial Permeability Transition, on Isoflurane-Induced and Ischemic Postconditioning in Rabbits
Anesth Analg 2006 102: 1355-1360. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Inhibition of the antiapoptotic regulatory protein Bcl-2 abolishes myocardial protection produced by brief exposure to isoflurane or repetitive, transient ischemic episodes during early reperfusion in rabbits. In contrast, inhibition of Bcl-2 did not affect protection afforded by cyclosporin A, a direct mitochondrial permeability transition pore (mPTP) antagonist. The results suggest that Bcl-2 mediates isoflurane-induced and ischemic postconditioning by indirectly modulating mPTP activity in vivo.

The Analgesic Efficacy of Acetaminophen, Ketoprofen, or Their Combination for Pediatric Surgical Patients Having Soft Tissue or Orthopedic Procedures
Anesth Analg 2006 102: 1365-1371. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We compared the analgesic efficacy of the combination of acetaminophen 60 mg/kg rectally plus 40 mg/kg orally per 24 h and ketoprofen (a traditional nonsteroidal antiinflammatory drug) 4 mg/kg per 24 h IV with the single drugs in pediatric surgical inpatients. The combination produced better pain treatment than either single drug when evaluated by 24-h morphine requirement or objective pain scores.

An Evaluation of Efficacy of Balloon Inflation on Venous Cannulation Pain in Children: A Prospective, Randomized, Controlled Study
Anesth Analg 2006 102: 1372-1375. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Venipuncture is the most common painful event for hospitalized children. We observed that 20 s of forced exhalation during balloon inflation reduced both the incidence and severity of venipuncture pain. This reduction in venipuncture pain may be the combined effect of distraction and Valsalva.

What Postoperative Outcomes Matter to Pediatric Patients?
Anesth Analg 2006 102: 1376-1382. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We investigated, for the first time, which postoperative outcome is most important to pediatric patients using standard gamble techniques. The results suggest a difference between boys and girls, as well as a difference between children's and adults' preferences.

The Use of Oral Granisetron Versus Intravenous Ondansetron for Antiemetic Prophylaxis in Patients Undergoing Laparoscopic Surgery: The Effect on Emetic Symptoms and Quality of Recovery
Anesth Analg 2006 102: 1387-1393. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Preoperative administration of granisetron, 1 mg per os, was not significantly different from ondansetron, 4 mg IV, in preventing emetic symptoms and improving recovery after laparoscopic surgery. However, ondansetron was more cost-effective than granisetron for routine prophylaxis as a result of its lower cost and comparable antiemetic efficacy and patient satisfaction.

Contrasting Roles of the N-Methyl-d-Aspartate Receptor in the Production of Immobilization by Conventional and Aromatic Anesthetics
Anesth Analg 2006 102: 1397-1406. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Blockade of N-methyl-d-aspartate (NMDA) receptors by conventional inhaled anesthetics does not mediate the capacity of such anesthetics to produce immobility in the face of noxious stimulation. In contrast, for aromatic anesthetics, NMDA receptors mediate production of immobility in proportion to the capacity of such anesthetics to block the NMDA receptor.

Differential Modulation of Human N-Methyl-d-Aspartate Receptors by Structurally Diverse General Anesthetics
Anesth Analg 2006 102: 1407-1411. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We found that equianesthetic concentrations (1 minimum alveolar anesthetic concentration [MAC]) of 15 structurally diverse inhaled anesthetics produced a sixfold range of inhibition of the human N-methyl-d-aspartate (NMDA) receptor, a finding that may be useful in a determination of the contribution of NMDA receptor inhibition to the MAC of inhaled anesthetics.

Do N-Methyl-d-Aspartate Receptors Mediate the Capacity of Inhaled Anesthetics to Suppress the Temporal Summation that Contributes to Minimum Alveolar Concentration?
Anesth Analg 2006 102: 1412-1418. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Blockade of N-methyl-d-aspartate receptors may explain the action of a few inhaled anesthetics, as defined by MAC, but may have minimal relevance for immobilization produced by most commonly used inhaled anesthetics.

The Minimum Alveolar Anesthetic Concentration of 2-, 3-, and 4-Alcohols and Ketones in Rats: Relevance to Anesthetic Mechanisms
Anesth Analg 2006 102: 1419-1426. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The position of the C-OH group of an alcohol or the C=O group of a ketone (that is, the length of the acyl carbon chain extending from the C-OH or C=O group) is not a better predictor of anesthetic potency than the total length of the carbon chain or the affinity of the alcohol or ketone to a lipid (olive oil) phase.

Bronchial Mucus Transport Velocity in Patients Receiving Propofol and Remifentanil Versus Sevoflurane and Remifentanil Anesthesia
Anesth Analg 2006 102: 1427-1430. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Anesthetic drugs may depress bronchial clearance. Using an in vivo method, we demonstrated significantly more depression of bronchial clearance in patients anesthetized with sevoflurane compared with propofol. This might have an impact on the use of these drugs in patients at high risk for pulmonary complications.

Novel Depots of Buprenorphine Prodrugs Have a Long-Acting Antinociceptive Effect
Anesth Analg 2006 102: 1445-1451. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The antinociceptive effects of three novel depots of buprenorphine esters were evaluated. We found that the novel depots of buprenorphine esters buprenorphine propionate, enanthate, and decanoate had a long duration of antinociceptive effect after IM injections in rats. This result is valuable for the development of long-acting analgesia for pain management.

Naloxone Does Not Increase the Minimum Alveolar Anesthetic Concentration of Sevoflurane in Mice (Brief Report)
Anesth Analg 2006 102: 1452-1455. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The opioid antagonist naloxone does not increase the minimum alveolar anesthetic concentration of sevoflurane in mice. Opioid receptors do not mediate the capacity of inhaled anesthetics to suppress movement in response to noxious stimulation.

The Impact of Therapy on Quality of Life and Mood in Neuropathic Pain: What Is the Effect of Pain Reduction?
Anesth Analg 2006 102: 1473-1479. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We evaluated the relationship between analgesia and mood/quality of life using outcomes from a recent clinical trial. Treatment-induced analgesia was shown to correlate with improvement in mood and quality of life. These results suggest that greater analgesic efficacy may lead to larger improvements in mood/quality of life.

Dysregulation of Cellular Calcium Homeostasis in Chemotherapy-Evoked Painful Peripheral Neuropathy
Anesth Analg 2006 102: 1485-1490. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Paclitaxel and vincristine often produce a pain syndrome that compromises their usefulness as anticancer drugs. The experiments described here suggest that the pain may be caused by an impairment of neuronal or glial ability to properly regulate intracellular Ca2+. A possible underlying pathology could be impaired mitochondrial Ca2+ regulation.

Predicting Anesthesia Times for Diagnostic and Interventional Radiological Procedures
Anesth Analg 2006 102: 1491-1500. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Anesthesia times for individual diagnostic radiological procedures (e.g., magnetic resonance imaging) can be based on systematic rules from the facility's experts. In contrast, a series of interventional radiological procedures performed on the same day can be scheduled consecutively up to a calculated time (e.g., 4 pm), assuring that the anesthesia team usually finishes before the end of the workday (6 pm).

Selective Recruitment Maneuvers for Lobar Atelectasis: Effects on Lung Function and Central Hemodynamics: An Experimental Study in Pigs
Anesth Analg 2006 102: 1504-1510. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Lobar lung collapse is common after anesthesia and surgery. A standard, general (global) lung inflation maneuver is usually effective in improving lung function but may cause significant cardiovascular depression. This experimental study shows that selective inflation of a collapsed lobe via a balloon catheter is effective and has no significant circulatory side effects.

The Synergistic Effects of Pentoxifylline on Systemic and Regional Perfusion After Hemorrhage and Hypertonic Resuscitation
Anesth Analg 2006 102: 1518-1524. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Pentoxifylline (PTX) has beneficial effects when administrated after hemorrhagic shock, restoring cardiac output and improving splanchnic perfusion. We tested the hypothesis that a combination of small volumes of hypertonic saline solution and PTX in the initial treatment of hemorrhagic shock provides synergistic hemodynamic benefits.

Precordial Doppler Probe Placement for Optimal Detection of Venous Air Embolism During Craniotomy
Anesth Analg 2006 102: 1543-1547. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: For early detection of venous air embolism, accurate precordial Doppler probe verification with test injections is crucial. Left parasternal Doppler probe placement was at least as sensitive to test injections as right parasternal placement. Vigorous central test injection may result in false positive verification of laterally placed precordial Doppler probes.

Unrecognized Drug-Drug Interactions: A Cause of Intraoperative Cardiac Arrest? (Case Report)
Anesth Analg 2006 102: 1569-1572. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This case report uses the emerging literature on the hepatic CYP450 enzyme system to provide an analysis of how multiple drug-drug interactions had a catastrophic effect in a patient receiving an otherwise uncomplicated anesthetic. We believe that evaluations in the field of anesthetic pharmacology will increasingly be based on this type of analysis.

A Comparison of Sister Chromatid Exchanges in Lymphocytes of Anesthesiologists to Nonanesthesiologists in the Same Hospital
Anesth Analg 2006 102: 1573-1577. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This prospective study demonstrates that the incidence of sister chromatid exchanges in anesthesiologists exposed to waste anesthetic gases such as sevoflurane and nitrous oxide is more frequent in unexposed physicians in the same hospital. The increase of sister chromatid exchanges in anesthesiologists is reversible if they work free from exposure for 2 mo.

Tactile Fade Detection with Hand or Wrist Stimulation Using Train-of-Four, Double-Burst Stimulation, 50-Hertz Tetanus, 100-Hertz Tetanus, and Acceleromyography
Anesth Analg 2006 102: 1578-1584. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: To detect residual neuromuscular blockade, tactile evaluation of 50-Hz tetanic, train-of-four (TOF), or double-burst fade lacks sensitivity. Fade after a 100-Hz tetanus is unreliable. An acceleromyographic TOF ratio of 1.0 is recommended to exclude residual paralysis. Stimulation at the hand and the wrist yields similar results for tactile evaluation.
