The Incidence and Prediction of Automatically Detected Intraoperative Cardiovascular Events in Noncardiac Surgery
Anesth Analg 2004 98: 569-577. [Abstract] [Full Text]  

IMPLICATIONS: The objective of this study was to evaluate prognostic models for quality assurance purposes to predict the occurrence of automatically detected intraoperative cardiovascular events in 58,458 patients undergoing noncardiac surgery. Two newly developed models showed good discrimination but, because of reduced calibration, their clinical use is limited. The ASA physical status classification and the Revised Cardiac Risk Index are unsuitable for the prediction of intraoperative cardiovascular events.

Prophylactic Treatment with Desmopressin Does Not Reduce Postoperative Bleeding After Coronary Surgery in Patients Treated with Aspirin Before Surgery
Anesth Analg 2004 98: 578-584. [Abstract] [Full Text]  

IMPLICATIONS: Continuation of aspirin until the day before coronary artery bypass grafting may increase postoperative bleeding. The administration of desmopressin to these patients after the neutralization of heparin with protamine sulfate does not reduce postoperative bleeding.

Amplification by Hyperoxia of Coronary Vasodilation Induced by Propofol
Anesth Analg 2004 98: 595-603. [Abstract] [Full Text]  

IMPLICATIONS: Propofol induced a coronary vasodilation that was amplified in the presence of hyperoxia. This phenomenon does not seem to be related to previous coronary vasoconstriction. The myocardial effects of propofol were not significantly modified in the presence of hyperoxia.

Damage to Pulmonary Artery Catheter During Transmyocardial Laser Revascularization (Case Report)
Anesth Analg 2004 98: 614-616. [Abstract] [Full Text]  

IMPLICATIONS: We report an unusual case of pulmonary artery catheter (PAC) damage during transmyocardial laser revascularization (TMLR). This observation should alert the anesthesiologist to the fact that the PAC may be damaged when TMLR is performed on the right side of the heart. We recommend that the PAC be withdrawn during this procedure.

PEDIATRIC ANESTHESIA:

Frederick A. Robertson and George M. Hoffman
Clinical Evaluation of the Effects of Signal Integrity and Saturation on Data Availability and Accuracy of Masimo SET® and Nellcor N-395 Oximeters in Children
Anesth Analg 2004 98: 617-622. [Abstract] [Full Text]  

IMPLICATIONS: We compared new pulse oximeters from Nellcor and Masimo and found that, with good signal conditions, both new devices performed similarly to older technology. Overall, Masimo reported less data as questionable than Nellcor. With poor signal conditions or during hypoxemia, the new devices are not clinically equivalent to each other or to the older technology.

Comparison of Recovery Profile After Ambulatory Anesthesia with Propofol, Isoflurane, Sevoflurane and Desflurane: A Systematic Review
Anesth Analg 2004 98: 632-641. [Abstract] [Full Text]  

IMPLICATIONS: A systematic analysis of the literature comparing postoperative recovery after propofol, isoflurane, desflurane, and sevoflurane-based anesthesia in adults demonstrated that early recovery was faster in the desflurane and sevoflurane groups. The incidence of nausea and vomiting were less frequent with propofol.

Attenuation of Gap-Junction-Mediated Signaling Facilitated Anesthetic Effect of Sevoflurane in the Central Nervous System of Rats
Anesth Analg 2004 98: 647-652. [Abstract] [Full Text]  

IMPLICATIONS: The intracerebroventricular administration of the gap-junction inhibitor, carbenoxolone, reduced the MAC of sevoflurane, and sevoflurane suppressed the signaling through gap-junctions in the central nervous system. The inhibition of gap-junctions may be one of the mechanisms and the site of action of sevoflurane.

Functional Inhibition by Methadone of N-Methyl-D-Aspartate Receptors Expressed in Xenopus Oocytes: Stereospecific and Subunit Effects
Anesth Analg 2004 98: 653-659. [Abstract] [Full Text]  

IMPLICATIONS: At clinically achievable concentrations, methadone inhibits functional N-methyl-D-aspartate receptors. These results indicate a unique mode of action by this opioid that may enhance its ability to treat chronic pain and to limit opioid tolerance.

The Effects of Hexanol on G{alpha}i Subunits of Heterotrimeric G Proteins
Anesth Analg 2004 98: 660-7. [Abstract] [Full Text]  

IMPLICATIONS: Although the {alpha} subunit of heterotrimeric G proteins is a potential target of anesthetics, we found no evidence that hexanol affects the ability of the G{alpha}i subunit to bind or hydrolyze guanosine triphosphate, either in purified subunits or in subunits derived from smooth muscle cell membranes. This finding implies that this is not a mechanism by which hexanol interferes with receptor-G protein function.

Peroxynitrite Decreases Rabbit Tissue Factor Activity In Vitro
Anesth Analg 2004 98: 668-671. [Abstract] [Full Text]  

IMPLICATIONS: Tissue factor (TF) initiates physiological coagulation in vivo. Hepatoenteric ischemia-reperfusion injury is associated with peroxynitrite (OONO-) formation, coagulopathy and decreased TF activity in rabbits. We determined that OONO- decreased rabbit TF activity in vitro via thrombelastography(R).

Local Anesthetic Properties of a Novel Derivative, N-Methyl Doxepin, Versus Doxepin and Bupivacaine
Anesth Analg 2004 98: 672-676. [Abstract] [Full Text]  

IMPLICATIONS: N-methyl doxepin and doxepin are both potent Na+ channel blockers; they elicit rat sciatic nerve block lasting longer than that induced by bupivacaine and seem to be nontoxic to peripheral nerves at concentrations up to 10 mM.

Vasodilation Increases the Threshold for Bupivacaine-Induced Convulsions in Rats
Anesth Analg 2004 98: 677-682. [Abstract] [Full Text]  

IMPLICATIONS: Bupivacaine, a long-acting local anesthetic, induces central nervous system toxicity when its plasma concentration is increased. Nicardipine and phentolamine increased the cumulative dose but did not affect the threshold plasma concentrations, required for bupivacaine-induced convulsions, suggesting that both nicardipine and phentolamine inhibited the increase in the plasma concentration of bupivacaine by inducing peripheral vasodilation.

Pretreatment with Thiopental for Prevention of Pain Associated with Propofol Injection
Anesth Analg 2004 98: 683-686. [Abstract] [Full Text]  

IMPLICATIONS: Pain associated with IV injection of propofol is seen in 28%-90% patients. Pretreatment with thiopental 0.25 mg/kg and 0.5 mg/kg after manual venous occlusion for 1 min effectively attenuated pain associated with propofol injection. Thiopental 0.5 mg/kg was the most effective in prevention of propofol pain and can be used routinely.

The Pharmacodynamic Effects of a Lower-Lipid Emulsion of Propofol: A Comparison with the Standard Propofol Emulsion
Anesth Analg 2004 98: 687-691. [Abstract] [Full Text]  

IMPLICATIONS: The pharmacodynamic profile of a lower-lipid containing emulsion of propofol (Ampofol(R)) was compared with Diprivan(R) when administered for induction and maintenance of general anesthesia. This preliminary study demonstrated that the two formulations of propofol were equivalent with respect to their induction and maintenance properties. However, Ampofol(R) was associated with a more frequent incidence of pain on injection.

Dextromethorphan-Associated Epidural Patient-Controlled Analgesia Provides Better Pain- and Analgesics-Sparing Effects than Dextromethorphan-Associated Intravenous Patient-Controlled Analgesia After Bone-Malignancy Resection: A Randomized, Placebo-Controlled, Double-Blinded Study
Anesth Analg 2004 98: 714-722. [Abstract] [Full Text]  

IMPLICATIONS: Patients undergoing bone-malignancy surgery under combined general and epidural anesthesia received randomly patient-controlled epidural analgesia (PCEA) or IV patient-controlled analgesia (PCA) postoperatively and dextromethorphan (DM) 90 mg or placebo double-blindly for 3 days (n = 30/group/set). The DM effect was recorded with minimal untoward effects: it afforded better pain control and reduced the demand for analgesics compared with the placebo, especially when associated with PCEA. DM patients ambulated earlier than placebo recipients.

Reduction of ß-Endorphin-Containing Immune Cells in Inflamed Paw Tissue Corresponds with a Reduction in Immune-Derived Antinociception: Reversible by Donor Activated Lymphocytes
Anesth Analg 2004 98: 723-729. [Abstract] [Full Text]  

IMPLICATIONS: The immune system not only contributes to inflammation, but also provides localized analgesia. A depleted immune system results in a reduction of immune-derived analgesia and a potentiation of inflammatory pain. Donor activated lymphocytes reverse these effects, highlighting the importance of a functional immune system in inflammatory pain.

Analgesia After Total Knee Arthroplasty: Is Continuous Sciatic Blockade Needed in Addition to Continuous Femoral Blockade? (Brief Report)
Anesth Analg 2004 98: 747-749. [Abstract] [Full Text]  

IMPLICATIONS: A child with neurofibromatosis, scoliosis, and a chest wall deformity presenting for spinal fusion developed severe hypotension while prone. This was due to compression of the heart by the sternum, not compression of the great vessels by neurofibromas. Sternal pressure in prone patients with chest wall deformities should be avoided. Unique management included the use of transesophageal echocardiography to determine the cause of the hypotension.

Is Physician Anesthesia Cost-Effective?
Anesth Analg 2004 98: 750-757. [Abstract] [Full Text]  

IMPLICATIONS: Recent outcome studies suggest improved patient outcomes when physicians medically direct nurse anesthetists versus anesthesia care delivered with nonmedically directed nurses. The relative cost-effectiveness of this practice model is, however, unknown. This economic analysis suggests that outcome gains with physician anesthesia may be obtained at cost savings or, under conservative assumptions, at a cost deemed reasonable by society.

Functional Residual Capacity and Respiratory Mechanics as Indicators of Aeration and Collapse in Experimental Lung Injury (Technical Communication)
Anesth Analg 2004 98: 782-789. [Abstract] [Full Text]  

IMPLICATIONS: Lung injury was quantified on computed tomography and related to monitored values of functional residual capacity and mechanical properties of the respiratory system. We found the functional residual capacity to be a more sensitive marker of the lung perturbations than the compliance. It might be of value to include functional residual capacity in the monitoring of acute lung injury.

The Effect of Bupivacaine on Myocardial Tissue Hypoxia and Acidosis During Ventricular Fibrillation (Technical Communication)
Anesth Analg 2004 98: 790-795. [Abstract] [Full Text]  

IMPLICATIONS: In this animal study pretreatment with bupivacaine attenuated the progression of myocardial acidosis during ventricular fibrillation. The dogs regained normal hemodynamic variables after lipid infusion. The findings suggest such that bupivacaine may protect the heart against ischemic acidosis.
