Renal Dysfunction After Cardiac Surgery with Normothermic Cardiopulmonary Bypass: Incidence, Risk Factors, and Effect on Clinical Outcome
Anesth Analg 2003 96: 1258-1264. [Abstract] [Full Text]  

IMPLICATIONS: We found that postoperative renal dysfunction was a frequent and severe complication after normothermic cardiac surgery, independently associated with poor outcome. Independent predictors of this complication were advanced age, active endocarditis, and recent (within 48 h) radiocontrast agent administration (the only preoperative modifiable factor), as well as postoperative hemodynamic dysfunction.

Evaluating Surrogate Measures of Renal Dysfunction After Cardiac Surgery
Anesth Analg 2003 96: 1265-1273. [Abstract] [Full Text]  

IMPLICATIONS: A convenient surrogate measure of renal function is needed for evaluating renal-protective therapies in cardiac surgery. We evaluated the performance of serum creatinine concentration and calculated creatinine clearance for predicting dialysis, mortality, and prolonged hospitalization. Both measures were correlated with clinical outcomes. Creatinine clearance had the advantage of a distribution suitable for parametric statistical tests.

The Effect of Pericardial Restraint, Atrial Pacing, and Increased Heart Rate on Left Ventricular Systolic and Diastolic Function in Patients Undergoing Cardiac Surgery
Anesth Analg 2003 96: 1274-1279. [Abstract] [Full Text]  

IMPLICATIONS: Pericardial restraint or the institution of atrial pacing do not alter left ventricular function, as assessed by pulmonary artery catheter and transesophageal echocardiography measurements. Diastolic (but not systolic) measurements showed inconsistency with increased heart rate.

Changes in Respiratory Mechanics During Cardiac Surgery
Anesth Analg 2003 96: 1280-1287. [Abstract] [Full Text]  

IMPLICATIONS: We observed that cardiopulmonary bypass deteriorates lung function by inducing a heterogeneous airway constriction, whereas no such effects were observed in patients undergoing cardiac surgery without bypass. The impairment in parenchymal mechanics, which was obtained in both groups, may result from peripheral airway closure and/or be a consequence of mediator release.

Guiding Surgical Cannulation of the Inferior Vena Cava with Transesophageal Echocardiography
Anesth Analg 2003 96: 1288-1293. [Abstract] [Full Text]  

IMPLICATIONS: Correct positioning of the venous cannula draining blood to the cardiopulmonary bypass circuit is important. Intraoperative transesophageal echocardiography allows satisfactory determination of the cannula position in nearly all patients. Ten percent of venous cannulae are primarily positioned in the right hepatic vein and not in the inferior vena cava as intended.

The Effects of Isoflurane on the Cardiac Slowly Activating Delayed-Rectifier Potassium Channel in Guinea Pig Ventricular Myocytes
Anesth Analg 2003 96: 1308-1315. [Abstract] [Full Text]  

IMPLICATIONS: The effects of a volatile anesthetic, isoflurane, were determined on a cardiac potassium channel current, IKs, a major ionic component underlying the cardiac action potential. The result shows that IKs is significantly inhibited by isoflurane. This may contribute to anesthetic-induced changes in the electrocardiogram, particularly the prolongation of the QT interval.

An Assessment of Different Filter Systems for Extracorporeal Elimination of Bivalirudin: An In Vitro Study
Anesth Analg 2003 96: 1316-1319. [Abstract] [Full Text]  

IMPLICATIONS: Bivalirudin is a new, direct thrombin inhibitor. We investigated the extracorporeal elimination rate of different hemofilters and one plasmapheresis filter for bivalirudin. Our data show that bivalirudin can be effectively eliminated via hemofiltration and plasmapheresis, although there were significant differences in the elimination rates among the filter systems investigated.

Tracheal Extubation of Deeply Anesthetized Pediatric Patients: A Comparison of Desflurane and Sevoflurane
Anesth Analg 2003 96: 1320-1324. [Abstract] [Full Text]  

IMPLICATIONS: Deep extubation of children can be performed safely with desflurane or sevoflurane. Airway problems occur more frequently with desflurane. Awakening occurs more quickly with desflurane. Midazolam premedication has a greater effect on emergence times than does the choice of inhaled anesthetic. Emergence agitation occurs frequently with either technique.

Intravenous Lidocaine as Adjuvant to Sevoflurane Anesthesia for Endotracheal Intubation in Children (Brief Report)
Anesth Analg 2003 96: 1325-1327. [Abstract] [Full Text]  

IMPLICATIONS: Supplementing a sevoflurane induction of anesthesia in children with IV lidocaine 2 mg/kg can suppress cough after tracheal intubation and thus improve intubating conditions. In addition, lidocaine minimizes blood pressure fluctuations after tracheal intubation.

Remifentanil With Thiopental for Tracheal Intubation Without Muscle Relaxants
Anesth Analg 2003 96: 1336-1339. [Abstract] [Full Text]  

IMPLICATIONS: We evaluated in a double-blinded manner the dose requirements for remifentanil with thiopental without muscle relaxants for obtaining acceptable intubation condition. Our results show that remifentanil 4 {micro}g/kg administered before thiopental provided excellent or satisfactory intubation condition in 94% of patients.

Modulation of Noninactivating K⁺ Channels in Rat Cerebellar Granule Neurons by Halothane, Isoflurane, and Sevoflurane
Anesth Analg 2003 96: 1340-1344. [Abstract] [Full Text]  

IMPLICATIONS: The volatile anesthetics halothane, isoflurane, and sevoflurane, reversibly enhanced a noninactivating outwardly rectifying K+ current in rat cerebellar granule neurons. These findings support a model of anesthesia that includes a site of action at baseline K+ channels.

Mutation of KCNK5 or Kir3.2 Potassium Channels in Mice Does Not Change Minimum Alveolar Anesthetic Concentration
Anesth Analg 2003 96: 1345-1349. [Abstract] [Full Text]  

IMPLICATIONS: Mice harboring mutations in either of two different potassium channels have minimum alveolar anesthetic concentration (MAC) values that do not differ from MAC values found in control mice. Such findings do not support the notion that these potassium channels mediate the capacity of inhaled anesthetics to produce immobility in the face of noxious stimulation.

Halothane and Isoflurane Have Additive Minimum Alveolar Concentration (MAC) Effects in Rats
Anesth Analg 2003 96: 1350-1353. [Abstract] [Full Text]  

IMPLICATIONS: Despite differences in their capacities to inhibit spinal dorsal horn cells, isoflurane and halothane are additive in their ability to suppress movement in response to a noxious stimulus.

Enflurane Decreases Glutamate Neurotransmission to Spinal Cord Motor Neurons by Both Pre- and Postsynaptic Actions
Anesth Analg 2003 96: 1354-1359. [Abstract] [Full Text]  

IMPLICATIONS: Explanations proposed for anesthetic-induced central nervous system depression include enhancement of synaptic inhibition and depression of excitation. The results reported herein suggest that, in the case of enflurane, the mechanism is a shift in the balance toward inhibition. Excitation is uniformly depressed by multiple mechanisms, whereas some anesthetic actions tend to enhance inhibition.

The Influence of Hemorrhagic Shock on Etomidate: A Pharmacokinetic and Pharmacodynamic Analysis
Anesth Analg 2003 96: 1360-1368. [Abstract] [Full Text]  

IMPLICATIONS: Hemorrhagic shock produced minimal changes in the pharmacokinetics and no change in the pharmacodynamics of etomidate in swine. These results suggest that, unlike other sedative hypnotics and opioids, minimal adjustment in the dose of etomidate is required to achieve the same drug effect during hemorrhagic shock.

Hemodynamic Interactions of Propofol and Dantrolene in Chronically Instrumented Dogs
Anesth Analg 2003 96: 1369-1373. [Abstract] [Full Text]  

IMPLICATIONS: Our study suggests that dantrolene reverses the hypotensive action produced by propofol and causes an increase in coronary blood flow with a decrease in coronary vascular resistance, but does not significantly change the negative inotropic effects.

Prevalence and Characteristics of Pain Induced by Percutaneous Liver Biopsy
Anesth Analg 2003 96: 1392-1396. [Abstract] [Full Text]  

IMPLICATIONS: Percutaneous liver biopsy is a painful procedure in most patients. Mild anxiolytic treatment plus local anesthetic infiltration seem to produce insufficient analgesia. A more profound analgesic treatment is required for better control of this pain.

Local Anesthetics Differentially Inhibit Sympathetic Neuron-Mediated and C Fiber-Mediated Synovial Neurogenic Plasma Extravasation
Anesth Analg 2003 96: 1397-1402. [Abstract] [Full Text]  

IMPLICATIONS: Local anesthetic wound irrigation is often used to treat postoperative surgical pain. Large concentrations of local anesthetics are usually used, and these concentrations may have possible neurotoxic and myotoxic effects. Our results demonstrate antiinflammatory effects of lidocaine and bupivacaine at concentrations smaller than used clinically.

Intrathecal Clonidine Reduces Hypersensitivity After Nerve Injury by a Mechanism Involving Spinal m4 Muscarinic Receptors
Anesth Analg 2003 96: 1403-1408. [Abstract] [Full Text]  

IMPLICATIONS: Neuraxial clonidine is an effective adjunct in the treatment of neuropathic pain and increases acetylcholine concentrations in cerebrospinal fluid in humans. These data in animals suggest that spinal m4 type muscarinic receptors are important to the effect of clonidine in treating hypersensitivity to touch after nerve injury.

Determining the Number of Beds in the Postanesthesia Care Unit: A Computer Simulation Flow Approach
Anesth Analg 2003 96: 1415-1423. [Abstract] [Full Text]  

IMPLICATIONS: Designing new operating room (OR) facilities implies many decisions on the number of ORs, postanesthesia care unit (PACU) beds, and on the staff of nurses and porters. To make these decisions, managers can use rules of thumb or recommendations. Our study highlights the interest of using flow simulation to validate these choices. In this case study we determine the number of PACU beds and porter staff and assess the impact of decreasing the number of porters on PACU bed requirements.

Educating Patients About Anesthesia: A Systematic Review of Randomized Controlled Trials of Media-Based Interventions
Anesth Analg 2003 96: 1424-1431. [Abstract] [Full Text]  

IMPLICATIONS: The effectiveness of media-based interventions for educating patients about general process and risks of anesthesia were compared in this systematic review. The use of video and/or printed information can decrease patient anxiety and increase patient knowledge. However, patient satisfaction was similar between media-based intervention and nonintervention groups.

A Demographic, Service, and Financial Survey of Anesthesia Training Programs in the United States
Anesth Analg 2003 96: 1432-1446. [Abstract] [Full Text]  

IMPLICATIONS: A survey was conducted of anesthesia training program directors that demonstrated that their departments' financial conditions have been eroding over the years 2000 to 2002. During this same period of time, departments were receiving an increase in institutional support from $34,319/full-time equivalent (FTE) faculty in the year 2000 to $59,680/FTE in the year 2002. Although there seems to be an approximate 10% shortage in academic faculty, the number of departments with open positions has progressively decreased from 91% to 73% over the past 3 yr. On average, the financial condition of the training departments has deteriorated over the past 3 yr despite a significant increase in institutional support to enable departments to recruit and retain faculty in an era of an apparent national shortage of anesthesiologists.

Anesthetic Technique Influences Brain Temperature, Independently of Core Temperature, During Craniotomy in Cats
Anesth Analg 2003 96: 1460-1466. [Abstract] [Full Text]  

IMPLICATIONS: Deep barbiturate anesthesia reduced brain temperature independently of body temperature in cats and significantly more than the reduction seen with halothane anesthesia. The magnitude of temperature reduction was sufficient to account for cerebral protection by barbiturates independently of any other properties of the drug.

Electron Paramagnetic Resonance Assessment of Brain Tissue Oxygen Tension in Anesthetized Rats
Anesth Analg 2003 96: 1467-1472. [Abstract] [Full Text]  

IMPLICATIONS: Using in vivo electron paramagnetic resonance oximetry, we studied the patterns of cerebral tissue oxygenation (PtO2) during exposure to various inhaled and injected general anesthetics, and to varying levels of inspired oxygen. These data show that inhaled anesthetics result in larger levels of PtO2 in the brain than do several injectable anesthetics. The results highlight the experimental utility of electron paramagnetic resonance in measuring PtO2 during anesthesia and serve as a foundation for further study of PtO2 in response to physiologic perturbations and therapeutic interventions directed at preventing cerebral ischemia.

Epidural Ropivacaine Versus Bupivacaine for Labor: A Meta-Analysis
Anesth Analg 2003 96: 1473-1479. [Abstract] [Full Text]  

IMPLICATIONS: This metaanalysis of 23 randomized controlled trials shows that both ropivacaine and bupivacaine provide excellent labor analgesia. There was no significant difference between the two drugs in mode of delivery, maternal satisfaction, or neonatal outcomes. Whether or not there is a difference in motor block at clinically relevant doses is unresolved.

Lumbar Spondylodiscitis Caused by Propionibacterium acnes After Epidural Obstetric Analgesia (Case Report)
Anesth Analg 2003 96: 1486-1488. [Abstract] [Full Text]  

IMPLICATIONS: We report a case of Propionibacterium acnes spondylodiscitis after the placement of an epidural catheter for obstetric analgesia. This observation should alert the anesthesiologist to the fact that infection, although rare, may occur after uneventful epidural analgesia in the healthy parturient and reinforces the importance of aseptic technique during epidural catheter insertion.

Management of a Parturient with a History of Local Anesthetic Allergy (Case Report)
Anesth Analg 2003 96: 1489-1490. [Abstract] [Full Text]  

IMPLICATIONS: The management of parturients with a strong history of allergy to local anesthetics poses significant challenges to the obstetric anesthesiologist. We recommend that when such patients have a strong desire to receive labor analgesia with local anesthetics, they undergo provocative challenge testing with preservative-free bupivacaine performed in labor and delivery with preparations for emergent cesarean delivery after 24-wk gestation.

Differing Incidences of Relevant Hypotension with Combined Spinal-Epidural Anesthesia and Spinal Anesthesia
Anesth Analg 2003 96: 1491-1495. [Abstract] [Full Text]  

IMPLICATIONS: This study, based on a large number of patients with a retrospective design by using on-line recorded data, suggests that spinal anesthesia as part of combined spinal-epidural anesthesia may more often lead to relevant hypotension than spinal anesthesia alone. Preexisting arterial hypertension and a sensory block height exceeding T6 are major risk factors for the development of this complication.
