Neither the Accuracy nor the Precision of Thermal Dilution Cardiac Output Measurements Is Altered by Acute Tricuspid Regurgitation in Pigs
Anesth Analg 2004 98: 884-890. [Abstract] [Full Text]  

IMPLICATIONS: Cardiac output is a valuable measurement that guides the medical care of patients with heart and lung disease. This study demonstrates that the thermal dilution technique of determining cardiac output is valid when acute tricuspid valve regurgitation is present in pigs.

Inotropes Improve Right Heart Function in Patients Undergoing Aortic Valve Replacement for Aortic Stenosis
Anesth Analg 2004 98: 891-902. [Abstract] [Full Text]  

IMPLICATIONS: Compared with placebo, both epinephrine and milrinone similarly improved biventricular performance after aortic valve replacement, with a greater impact on right ventricular function. Choice of either inotropic drug should be driven by blood pressure and hemodynamic goals in this setting.

Intrathecal Morphine Reduces Infarct Size in a Rat Model of Ischemia-Reperfusion Injury
Anesth Analg 2004 98: 903-909. [Abstract] [Full Text]  

IMPLICATIONS: Our findings suggest that spinally-administered morphine provides a previously unrecognized cardioprotective benefit. In anesthetized rats subjected to ischemia-reperfusion injury, we show that very small doses of intrathecal morphine reduce infarct size in rats, and this benefit is as great as that provided by much larger doses of IV morphine.

Accurate Central Venous Port-A Catheter Placement: Intravenous Electrocardiography and Surface Landmark Techniques Compared by Using Transesophageal Echocardiography
Anesth Analg 2004 98: 910-914. [Abstract] [Full Text]  

IMPLICATIONS: Intravenous electrocardiography guidance to position catheters obtains a satisfactory catheter tip placement that is in accordance with transesophageal echocardiography views. The surface landmark technique does not result in reliable placement at the superior vena cava-right atrium junction.

The Effect of Erythropoietin on Allogeneic Blood Requirement in Patients Undergoing Elective Liver Resection: A Model Simulation
Anesth Analg 2004 98: 921-926. [Abstract] [Full Text]  

IMPLICATIONS: A mathematical model simulation suggests that the routine preoperative administration of erythropoietin to patients scheduled for major and median liver resection presenting with a preoperative hemoglobin concentration in the range 10-13 g/dL could reduce blood transfusion requirements. However, the cost/benefit ratio warrants consideration.

Cardiac Anesthesiology, Professionalism and Ethics: A Microcosm of Anesthesiology and Medicine (Special Article)
Anesth Analg 2004 98: 927-934. [Abstract] [Full Text]  

IMPLICATIONS: Cardiac anesthesiologists have contributed to enhanced survival and decreased morbidity of patients with heart disease undergoing surgery. These achievements do not by themselves fulfill the moral obligations incurred by the concept of Civic Professionalism, however. Cardiac anesthesiologists, in common with all physicians, must share the obligation to advocate for the human right of universal access to health care.

Perioperative Rofecoxib Improves Early Recovery After Outpatient Herniorrhaphy
Anesth Analg 2004 98: 970-975. [Abstract] [Full Text]  

IMPLICATIONS: Rofecoxib (50 mg per os), given before and after surgery, was effective in improving postoperative pain management, as well as the speed and quality of recovery after outpatient inguinal herniorrhaphy. However, it failed to accelerate the postdischarge resumption of normal activities of daily living.

Skin Sensitivity to Rocuronium and Vecuronium: A Randomized Controlled Prick-Testing Study in Healthy Volunteers
Anesth Analg 2004 98: 986-989. [Abstract] [Full Text]  

IMPLICATIONS: Building concentration-skin response curves to prick tests with rocuronium and vecuronium in healthy, nonatopic, anesthesia-naive male and female volunteers demonstrated that the nonreactive concentration for both muscle relaxants is the 1:1000 dilution of the stock solutions. Our observation calls into question the past practice of prick-testing skin for sensitivity to neuromuscular blocking drugs by using undiluted solutions.

A Comparison of Liver Function After Hepatectomy in Cirrhotic Patients Between Sevoflurane and Isoflurane in Anesthesia with Nitrous Oxide and Epidural Block
Anesth Analg 2004 98: 990-993. [Abstract] [Full Text]  

IMPLICATIONS: In cirrhotic patients with Child-Pugh Grade A, isoflurane induced more of an increase in serum concentrations of liver enzymes after surgery than sevoflurane when combined with nitrous oxide and epidural block. However, the increases were small, and there was no clinical liver damage.

Isoflurane Pretreatment Supports Hemodynamics and Leukocyte Rolling Velocities in Rat Mesentery During Lipopolysaccharide-Induced Inflammation
Anesth Analg 2004 98: 999-1006. [Abstract] [Full Text]  

IMPLICATIONS: Isoflurane pretreatment supported hemodynamics and increased leukocyte rolling velocities in the mesenteric microcirculation during lipopolysaccharide-induced inflammation. Faster rolling velocities may reduce the incidence of inflammation by decreasing leukocyte-endothelial interactions and cellular injury.

Xenon and Isoflurane Differentially Modulate Lipopolysaccharide-Induced Activation of the Nuclear Transcription Factor KB and Production of Tumor Necrosis Factor- and Interleukin-6 in Monocytes
Anesth Analg 2004 98: 1007-1012. [Abstract] [Full Text]  

IMPLICATIONS: This study has shown that monocytes respond to lipopolysaccharide (LPS) in the presence of xenon with an increased activation of nuclear transcription factor (NF)-{kappa}B, whereas isoflurane inhibits LPS-induced activation of NF-{kappa}B. These findings suggest a possible molecular mechanism for the different effects of both anesthetics on monocyte tumor necrosis factor-{alpha} and interleukin-6 production.

The Effects of Propofol on Hypothalamic Paraventricular Nucleus Neurons in the Rat
Anesth Analg 2004 98: 1017-1023. [Abstract] [Full Text]  

IMPLICATIONS: We investigated the actions of propofol on the rat hypothalamic paraventricular nucleus neurons, which are involved in the control of cardiovascular and sympathetic functions. The results suggest that propofol enhancement of gamma-aminobutyric acidA-receptor mediated currents and inhibition of voltage-gated Ca2+ currents at the central level may be, at least in part, involved in general anesthetic-induced cardiovascular and sympathetic depression.

The Effect of Local Anesthetics on Monocyte mCD14 and Human Leukocyte Antigen-DR Expression
Anesth Analg 2004 98: 1024-9. [Abstract] [Full Text]  

IMPLICATIONS: Monocyte surface receptors have a crucial role in the host response to microbial infection. We investigated the effects of local anesthetics on monocyte mCD14 and human leukocyte antigen (HLA)-DR expression. Our results show that local anesthetics suppress HLA-DR expression on the surface of human monocytes.

Bispectral Index as an Indicator of Seizure Inducibility in Electroconvulsive Therapy Under Thiopental Anesthesia
Anesth Analg 2004 98: 1030-1035. [Abstract] [Full Text]  

IMPLICATIONS: We found that the bispectral index (BIS) score serves as an indicator of seizure inducibility in electroconvulsive therapy (ECT) under thiopental anesthesia and that the relationship between BIS score and seizure duration was not linear, suggesting that the pharmacological mechanisms by which thiopental and propofol suppress ECT seizure activity are different.

Preoperative Oral Rofecoxib Reduces Postoperative Pain and Tramadol Consumption in Patients After Abdominal Hysterectomy
Anesth Analg 2004 98: 1039-1043. [Abstract] [Full Text]  

IMPLICATIONS: This study was designed to determine whether the administration of a preoperative dose of rofecoxib to patients undergoing abdominal hysterectomy would decrease patient-controlled analgesia tramadol use or enhance analgesia. We conclude that the preoperative administration of oral rofecoxib provided a significant analgesic benefit and decreased the opioid requirements in patients undergoing abdominal hysterectomy.

Perioperative Intravenous Lidocaine Has Preventive Effects on Postoperative Pain and Morphine Consumption After Major Abdominal Surgery
Anesth Analg 2004 98: 1050-1055. [Abstract] [Full Text]  

IMPLICATIONS: The perioperative administration of systemic small-dose lidocaine reduces pain during surgery associated with the development of pronounced central hyperalgesia, presumably by affecting mechanoinsensitive nociceptors, because these have been linked to the induction of central sensitization and were shown to be particularly sensitive to small-dose lidocaine.

Intrathecal Clonidine and Bupivacaine Have Synergistic Analgesia for Acute Thermally or Inflammatory-Induced Pain in Rats
Anesth Analg 2004 98: 1056-1061. [Abstract] [Full Text]  

IMPLICATIONS: The analgesic interaction between intrathecally administered bupivacaine and clonidine was examined during acute thermal and inflammatory-induced pain in rats. The analgesia produced by the combination of these two drugs was synergistic in both acute thermal and inflammatory induced pain, with a decrease in behavioral side effects.

A Dose Ranging Study of Dexamethasone for Preventing Patient-Controlled Analgesia-Related Nausea and Vomiting: A Comparison of Droperidol with Saline
Anesth Analg 2004 98: 1066-1071. [Abstract] [Full Text]  

IMPLICATIONS: Morphine administration by patient-controlled analgesia (PCA) is often associated nausea and vomiting. In this double-blind study, the minimum effective dose of dexamethasone for reducing this complication was 8 mg. This was as effective as adding droperidol 0.1 mg/mL to the morphine PCA without causing drowsiness, restlessness or arrhythmias.

Acetylsalicylic Acid, Diclofenac, and Lornoxicam, but Not Rofecoxib, Affect Platelet CD 62 Expression
Anesth Analg 2004 98: 1082-1085. [Abstract] [Full Text]  

IMPLICATIONS: We compared the effect of rofecoxib and three nonselective nonsteroidal antiinflammatory drugs on platelet function, measured by CD 62 P expression. Platelet function was not altered by rofecoxib, but it was inhibited by aspirin, diclofenac, and lornoxicam. Rofecoxib may be safer than classic NSAIDs with respect to platelet function during the perioperative period.

Postoperative Epidural Anesthesia Preserves Lymphocyte, but Not Monocyte, Immune Function After Major Spine Surgery
Anesth Analg 2004 98: 1086-1092. [Abstract] [Full Text]  

IMPLICATIONS:Epidural analgesia affects the immune system. Postoperative epidural analgesia, compared with conventional IV opioid therapy, preserves lymphocyte rather than monocyte functions. An improvement of postoperative immune function by epidural analgesia therefore may improve postoperative resistance to infectious complications or to chronic pain states.

The Effects of Pretreatment with Lidocaine or Bupivacaine on the Spatial and Temporal Expression of c-Fos Protein in the Spinal Cord Caused by Plantar Incision in the Rat
Anesth Analg 2004 98: 1093-1098. [Abstract] [Full Text]  

IMPLICATIONS: Prevention of early pain by pretreatment with local anesthetics provides little benefit for postoperative pain relief in the plantar incision model, although c-Fos expression is suppressed. The number of c-Fos-expressing neurons is not necessarily correlated with pain behavior.

Patient Satisfaction with Preoperative Assessment in a Preoperative Assessment Testing Clinic
Anesth Analg 2004 98: 1099-1105. [Abstract] [Full Text]  

IMPLICATIONS: Patient satisfaction can serve as an important indicator of the quality of preoperative care delivered in Preoperative Assessment Testing Clinics (PATC). Information and communication, both from clinical and nonclinical service providers, remain the most important positive components, and the total duration of the clinic visit represents the most negative component, of patient satisfaction in a PATC.

Prolonged Cardiovascular Collapse Due to Unrecognized Latex Anaphylaxis (Case Report)
Anesth Analg 2004 98: 1124-1126. [Abstract] [Full Text]  

IMPLICATIONS: We describe a patient who experienced latex-induced intraoperative anaphylaxis. The event coincided with antibiotic administration, which prompted us to erroneously assume that the causative allergen was medication related. Allergy to latex must always be considered as a potential culprit of perioperative cardiovascular collapse.

The Comparative Effects of Desflurane and Isoflurane on Lumbar Cerebrospinal Fluid Pressure in Patients Undergoing Craniotomy for Supratentorial Tumors
Anesth Analg 2004 98: 1127-32. [Abstract] [Full Text]  

IMPLICATIONS: This is the largest study to date comparing the effects of desflurane and isoflurane on patients undergoing craniotomy for supratentorial mass lesion with evidence of midline shift or edema. Neither desflurane nor isoflurane significantly altered lumbar cerebrospinal fluid pressure when moderate hypocapnia was maintained.

Continuous Assessment of Cerebral Autoregulation in Subarachnoid Hemorrhage
Anesth Analg 2004 98: 1133-1139. [Abstract] [Full Text]  

IMPLICATIONS: The moving correlation coefficients between slow changes of arterial blood pressure and mean or systolic flow velocity, termed "Mx" and "Sx," respectively, characterize cerebral autoregulation but have not been applied to subarachnoid hemorrhage. A study in 15 patients revealed that Mx and Sx were significantly increased, indicating impaired autoregulation during vasospasm as compared with baseline, as well as on the side of vasospasm in comparison with the contralateral side.

Bispectral Index Values at Sevoflurane Concentrations of 1% and 1.5% in Lower Segment Cesarean Delivery
Anesth Analg 2004 98: 1140-1144. [Abstract] [Full Text]  

IMPLICATIONS: Bispectral index (BIS) values <60 are consistent with a high probability of unconsciousness. An end-tidal concentration of 1.5% sevoflurane maintained BIS values <60 during cesarean delivery, whereas 1% did not. Adverse effects were not seen with the use of larger concentrations of sevoflurane.

Epidural Infusions of Ropivacaine and Bupivacaine for Labor Analgesia: A Randomized, Double-Blind Study of Obstetric Outcome
Anesth Analg 2004 98: 1145-1152. [Abstract] [Full Text]  

IMPLICATIONS: In a randomized-controlled study, we found no major outcome advantage of continuous epidural infusion of ropivacaine 0.1% with fentanyl 0.0002% over bupivacaine 0.1% with fentanyl 0.0002% for labor analgesia. Although ropivacaine was associated with a shorter first stage of labor, the relative difference is probably of limited clinical importance, and there was no difference in the mode of delivery.

Intrathecal Sufentanil and Fetal Heart Rate Abnormalities: A Double-Blind, Double Placebo-Controlled Trial Comparing Two Forms of Combined Spinal Epidural Analgesia with Epidural Analgesia in Labor
Anesth Analg 2004 98: 1153-1159. [Abstract] [Full Text]  

IMPLICATIONS: Combined spinal epidural analgesia (CSE) produces pain relief during labor. Fetal heart rate changes after CSE using intrathecal sufentanil have been reported. We performed a randomized, blinded trial confirming that fetal heart rate changes are more frequent after CSE using 7.5 {micro}g of intrathecal sufentanil as compared with other forms of neuraxial labor analgesia.

Tramadol Added to 1.5% Mepivacaine for Axillary Brachial Plexus Block Improves Postoperative Analgesia Dose-Dependently
Anesth Analg 2004 98: 1172-1177. [Abstract] [Full Text]  

IMPLICATIONS: Tramadol's unique mechanism of action suggests efficacy as a local anesthetic adjunct for peripheral plexus blockade. Our study demonstrates that tramadol, added to mepivacaine for brachial plexus anesthesia, extends the duration and improves the quality of postoperative analgesia in a dose dependent fashion with acceptable side effects.

The Incidence of Lumbar Ligamentum Flavum Midline Gaps (Brief Report)
Anesth Analg 2004 98: 1178-1180. [Abstract] [Full Text]  

IMPLICATIONS: The ligamentum flavum is a crucial anatomical landmark for the safe performance of epidural anesthesia. However, the present study demonstrates some failure of the lumbar ligamentum flavum as a landmark. This may mean that, using a midline approach, one cannot always rely on the ligamentum flavum as a perceptible barrier to epidural needle advancement.
