A-Type and B-Type Natriuretic Peptides in Cardiac Surgical Procedures
Anesth Analg 2004 98: 11-19. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: A-type natriuretic peptide is primarily influenced by volume reloading of the heart after cross-clamp, whereas the secretion of B-type natriuretic peptide (BNP) is related to the duration of ischemia and long-term left ventricular pressure and/or volume overload. Preoperative BNP, but not postoperative BNP, concentrations predict long-term outcome after coronary artery bypass grafting.

Myocardial Protection Using Fructose-1,6-Diphosphate During Coronary Artery Bypass Graft Surgery: A Randomized, Placebo-Controlled Clinical Trial
Anesth Analg 2004 98: 20-29. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Fructose-1,6-diphosphate (FDP) may increase high-energy phosphate levels under anaerobic conditions and therefore ameliorate ischemic injury. A dose-ranging safety study for FDP was conducted in patients undergoing coronary artery surgery. Preischemic provision of FDP significantly improved cardiac function and reduced perioperative ischemic injury. These myocardial protective effects may improve patient outcome after cardiac surgery.

Clonidine Prolongs Spinal Anesthesia in Newborns: A Prospective Dose-Ranging Study
Anesth Analg 2004 98: 56-59. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Spinal anesthesia is suitable but often too short for complete surgery in newborns. This controlled, randomized, prospective, dose-ranging study was conducted in 75 neonates to test the hypothesis that clonidine could significantly lengthen bupivacaine spinal block. Clonidine 1 {micro}g/kg, added to spinal isobaric bupivacaine, doubles the duration of the block without significant deleterious hemodynamic or respiratory side effects.

Spinal Chloroprocaine Solutions: Density at 37° C and pH Titration
Anesth Analg 2004 98: 70-74. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Dextrose-free 2-chloroprocaine is hyperbaric relative to cerebrospinal fluid at 37{degrees}C, and therefore can be used for spinal anesthesia without dextrose. Bisulfite-free 2-chloroprocaine remains very acidic (pH <4.0). The pH can be increased to more than 7.0 with a small amount of bicarbonate (0.25-0.33 mL/10 mL).

Spinal 2-Chloroprocaine: A Comparison with Lidocaine in Volunteers
Anesth Analg 2004 98: 75-80. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The spinal anesthetic profile of chloroprocaine (40 mg) compares favorably with the same dose of spinal lidocaine. Reliable sensory and motor blockade with predictable duration and minimal side effects and without signs of transient neurological symptoms make chloroprocaine an attractive choice for outpatient spinal anesthesia.

Spinal 2-Chloroprocaine: A Dose-Ranging Study and the Effect of Added Epinephrine
Anesth Analg 2004 98: 81-88. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Hyperbaric spinal 2-chloroprocaine is effective and has an anesthetic profile appropriate for use in the surgical outpatient over the dose range of 30-60 mg without signs of transient neurologic symptoms. The addition of epinephrine is not recommended because of the frequent incidence of side effects.

Spinal 2-Chloroprocaine: The Effect of Added Fentanyl
Anesth Analg 2004 98: 89-94. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Spinal 2-chloroprocaine (40 mg) provides rapid onset and reliable blockade without signs of transient neurological symptoms, giving it a positive profile for ambulatory surgical settings. The addition of fentanyl appears to lengthen the regression to L1 dermatome and tourniquet time while minimally lengthening duration of block.

Spinal 2-Chloroprocaine: The Effect of Added Dextrose
Anesth Analg 2004 98: 95-101. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Spinal chloroprocaine provides adequate potency with reliable regression, seemingly without concerns of transient neurologic symptoms, and hence an appealing profile for outpatient surgery. The addition of dextrose does not alter peak block height or tolerance of thigh tourniquet, and increases the degree of residual bladder dysfunction.

Antagonism of Cisatracurium and Rocuronium Block at a Tactile Train-of-Four Count of 2: Should Quantitative Assessment of Neuromuscular Function Be Mandatory?
Anesth Analg 2004 98: 102-106. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: After the administration of cisatracurium or rocuronium, train-of-four (TOF) ratios <0.70 should rarely be observed in the postanesthesia care unit if neostigmine-assisted antagonism of residual block is delayed until the tactile TOF count at the thumb is 2 or more.

Pharmacodynamic Interactions Between Cisatracurium and Rocuronium
Anesth Analg 2004 98: 107-110. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We assessed the clinical effect of administering cisatracurium after an intubating dose of rocuronium in 60 patients undergoing isoflurane/nitrous oxide and oxygen anesthesia. The clinical duration of the first two maintenance doses of cisatracurium administered after rocuronium was significantly prolonged. This supports the contention that combinations of structurally dissimilar neuromuscular blocking drugs result in a synergistic effect.

Chronic Treatment with Antipsychotics Enhances Intraoperative Core Hypothermia
Anesth Analg 2004 98: 111-115. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Antipsychotics inhibit autonomic thermoregulation. This is caused by decreased heat production, increased heat loss, and impaired central action at the hypothalamus. Thus, schizophrenic patients receiving antipsychotics may have impaired intraoperative temperature regulation.

Are Peripheral Opioid Antagonists the Solution to Opioid Side Effects? (Medical Intelligence)
Anesth Analg 2004 98: 116-122. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The major analgesic effects of opioid medication are mediated within the brain and spinal cord. Many of the side effects of opioids are caused by activation of receptors outside these areas. Recently developed peripherally restricted opioid antagonists have the ability to block many opioid side effects without affecting analgesia.

Alaris AEP^TM Monitor’s "Click Detection" Does Not Help to Detect Inadvertent Disconnection of Headphones During Anesthesia
Anesth Analg 2004 98: 123-127. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Signal transmission of auditory evoked potentials can be suppressed by anesthetics, but also by disconnection of headphones. In the present study, we demonstrate that even the Alaris AEPTM monitor with the very new feature "Click Detection" was not able to detect the loss of headphones during general anesthesia with propofol and remifentanil.

Correlation of Bispectral Index and Guedel’s Stages of Ether Anesthesia (Technical Communication)
Anesth Analg 2004 98: 132-134. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: For the first time, bispectral index (BIS) has been studied in patients being anesthetized solely with ether. Ether both causes an increase and decrease in BIS during induction and emergence. The index observed during the surgical stage of ether anesthesia is probably the correct value for the depth of hypnosis because no other volatile anesthetic can produce the true anesthetic state when used alone. This value could be taken as the value to be attained when balanced anesthesia is being practiced.

Preoperative Rofecoxib Oral Suspension as an Analgesic Adjunct After Lower Abdominal Surgery: The Effects on Effort-Dependent Pain and Pulmonary Function
Anesth Analg 2004 98: 135-140. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Rofecoxib belongs to class of analgesics known as cyclooxygenase-2 inhibitors that reduce pain and inflammation with less risk of bleeding than standard nonsteroidal antiinflammatory drugs. We found that patients treated with rofecoxib 25 or 50 mg before open abdominal surgery required less IV morphine during the first day of recovery. Despite reductions in morphine requirements, rofecoxib-treated patients reported lower pain intensity scores at rest and after a vigorous cough. In the 50-mg group, improvements in pain control correlated with greater preservation of baseline cough effectiveness (vital capacity) at 12 h. These findings may offer clinical advantages in patients with preexisting pulmonary disease.

The Efficacy of Dexmedetomidine Versus Morphine for Postoperative Analgesia After Major Inpatient Surgery
Anesth Analg 2004 98: 153-158. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The use of dexmedetomidine for postoperative analgesia resulted in significantly less additional pain medication (morphine) and slower heart rates than a control group receiving only morphine. These outcomes may prove advantageous for patients who might be placed at higher risk by tachycardia or large doses of morphine.

The Pharmacokinetics and Efficacy of Ropivacaine Continuous Wound Instillation After Spine Fusion Surgery
Anesth Analg 2004 98: 166-172. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Postoperative pain after lumbar arthrodesis is related to soft tissue and muscle dissection and to manipulations and removal at the operation site. By blocking noxious stimuli from the surgical area, infiltration and wound perfusion with ropivacaine were more effective in controlling pain than systemic analgesia.

Amiodarone Decreases Heat, Cold, and Mechanical Hyperalgesia in a Rat Model of Neuropathic Pain
Anesth Analg 2004 98: 178-184. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Amiodarone was found to produce a statistically significant decrease in heat, cold, and mechanical hyperalgesia in a rat model of neuropathic pain after intraperitoneal injection. Considering its long half-life in humans, amiodarone has the potential to provide long lasting pain relief in neuropathic pain states.

Ventilation-Perfusion Distribution Related to Different Inspiratory Flow Patterns in Experimental Lung Injury
Anesth Analg 2004 98: 211-219. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In acute lung injury, mechanical ventilation with decelerating flow has been suggested to improve ventilation-perfusion distribution when compared with constant flow. We tested this hypothesis in an animal model. Contrary to the hypothesis, we found a more favorable ventilation-perfusion distribution during constant flow when compared with decelerating flow.

Risperidone and Exaggerated Hypotension During a Spinal Anesthetic (Case Report)
Anesth Analg 2004 98: 240-241. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Parturients receiving neuraxial blocks may be taking antipsychotic medications. Although the therapeutic effects of antipsychotic medications are mediated by dopaminergic and serotonergic antagonism, many possess alpha-adrenergic antagonist properties. We report a case of exaggerated hypotension during a spinal anesthetic for cesarean delivery that may have been a result of the alpha-adrenergic antagonism of risperidone.

Administration of 100% Oxygen Before Removal of the Laryngeal Mask Airway Does Not Affect Postanesthetic Arterial Partial Pressure of Oxygen
Anesth Analg 2004 98: 257-259. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The endotracheal tube and laryngeal mask airway are substantially different artificial airways used to ventilate the lungs of anesthetized patients. Breathing 100% oxygen before removing the endotracheal tube results in lung function defects. This study shows that oxygen breathing before removing the laryngeal mask airway has no effect on pulmonary function.
