Small Risk of Serious Neurologic Complications Related to Lumbar Epidural Catheter Placement in Anesthetized Patients
Anesth Analg 2003 96: 1547-1552. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We report no neurologic complications in 4298 patients undergoing epidural catheter placement while under general anesthesia. Although the risk of neurologic complications associated with lumbar epidural catheter placement in anesthetized patients is small, the relative risk compared with epidural catheterization in awake patients is unknown.

The Effects of Epidural and General Anesthesia on Tissue Oxygenation
Anesth Analg 2003 96: 1553-1557. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Epidural anesthesia significantly increased subcutaneous tissue oxygenation in the thigh both with and without general anesthesia. Although each increase was statistically significant, previous work suggests that the magnitude of these changes is unlikely to markedly reduce the risk of surgical wound infection.

Knowledge and Practice Regarding Prophylactic Perioperative Beta Blockade in Patients Undergoing Noncardiac Surgery: A Survey of Canadian Anesthesiologists
Anesth Analg 2003 96: 1558-1565. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: This survey found that anesthesiologists were aware of and supported the use of prophylactic perioperative ß blockers in patients with risk factors or known coronary artery disease; however, only 57% frequently prescribed perioperative ß blockers. A lack of awareness of the current "best" evidence was not a barrier to use.

Supplementing Transesophageal Echocardiography with Transthoracic Echocardiography for Monitoring Transcatheter Closure of Atrial Septal Defects with Attenuated Anterior Rim: A Case Series
Anesth Analg 2003 96: 1584-1588. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Transesophageal echocardiography can be useful for confirming successful deployment of the occluder in the majority of patients with atrial septal defect. In a small number of atrial septal defects with attenuated anterior superior rim which have unusual anterior inferior morphology, supplemental transthoracic echocardiography is required to verify successful deployment of the occluder when transesophageal echocardiography visualization fails to reliably diagnose adequate placement of the occluder.

The Contribution of the Coronary Concentrations of Propofol to Its Cardiovascular Effects in Anesthetized Sheep
Anesth Analg 2003 96: 1589-1597. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS:With use of selective coronary artery infusions in sheep, the coronary concentrations of propofol were shown to be the major contributor to the cardiac depression caused by propofol but were a less significant contributor to the hypotension caused by this drug. Models of the cardiovascular effects of propofol should account for these relationships.

Postoperative Analgesia in Children Undergoing Myringotomy and Placement Equalization Tubes in Ambulatory Surgery
Anesth Analg 2003 96: 1621-1624. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We compared four different analgesics in the management of pain after placement of pressure equalization tubes during myringotomy in children and demonstrated that ketorolac or butorphanol provided superior analgesia when compared with acetaminophen with codeine or plain acetaminophen. Children who received ketorolac versus butorphanol had less vomiting in the 24 h after surgery.

The Efficacy of Celecoxib Premedication on Postoperative Pain and Recovery Times After Ambulatory Surgery: A Dose-Ranging Study
Anesth Analg 2003 96: 1631-1635. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Oral premedication with celecoxib 400 mg was more effective than 200 mg in reducing postoperative pain and the need for rescue analgesic medication in the early postoperative period. However, neither dose of celecoxib was more effective than a placebo in facilitating the recovery process after outpatient surgery.

Can the Bispectral Index Be Used to Predict Seizure Time and Awakening After Electroconvulsive Therapy?
Anesth Analg 2003 96: 1636-1639. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The bispectral index (BIS) value immediately before the electroconvulsive therapy (ECT) stimulus correlates with the duration of the motor and electroencephalogram (EEG) seizure activity during methohexital anesthesia. In addition, the increase in the BIS value during the ECT-induced seizure was proportional to the duration of EEG seizure activity. However, the BIS value on awakening from anesthesia varied widely, from 29 to 97.

Postoperative Myalgia After Succinylcholine: No Evidence for an Inflammatory Origin
Anesth Analg 2003 96: 1640-1644. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Administration of dexamethasone before succinylcholine was not effective in decreasing the incidence or the severity of succinylcholine-induced postoperative myalgia. Furthermore, there was no significant relationship between postoperative myalgia and time course of interleukin-6 concentrations, a marker of inflammation. Pretreatment with dexamethasone is not justified to prevent postoperative myalgia after succinylcholine.

Sympathetic and Vascular Consequences from Remifentanil in Humans
Anesth Analg 2003 96: 1645-1650. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Remifentanil occasionally has been associated with hypotension, the mechanism of which is unclear. This study found that remifentanil directly causes the forearm arterial vasculature to dilate.

Effect-Site Concentration of Propofol for Recovery of Consciousness Is Virtually Independent of Fentanyl Effect-Site Concentration
Anesth Analg 2003 96: 1651-1655. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS:The effect-site concentration for propofol at awakening was virtually independent of the fentanyl effect-site concentration over the range of 0.8 to 3.0 ng/mL; however, 0.8 ng/mL of fentanyl was associated with inadequate postoperative analgesia, and 3.0 ng/mL of fentanyl was associated with respiratory toxicity. The optimal postoperative fentanyl effect-site concentration during recovery from propofol general anesthesia for laparotomy thus appears to be near 2 ng/mL.

The Effects of Local and Intravenous Anesthetics on Recombinant Rat VR1 Vanilloid Receptors
Anesth Analg 2003 96: 1656-1660. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Vanilloid receptors (VR1) are activated by capsaicin, the pain-producing component of hot chili peppers. We suggest that local (but not IV general) anesthetics may have inhibitory actions on this receptor.

-2 Adrenoreceptors Probably Do Not Mediate the Immobility Produced by Inhaled Anesthetics
Anesth Analg 2003 96: 1661-1664. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Although stimulation (agonism) of {alpha}-2 adrenoreceptors can decrease the inhaled anesthetic concentration required to produce immobility in the face of noxious stimulation, blockade of {alpha}-2 adrenoreceptors minimally affects the concentration. Thus, augmentation of the effect of {alpha}-2 adrenoreceptors is not an appreciable part of the mechanism whereby inhaled anesthetics produce immobility.

Inhibition of Human TREK-1 Channels by Bupivacaine
Anesth Analg 2003 96: 1665-1673. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The interaction of bupivacaine with human TREK-1 channels was studied with the patch-clamp technique. Bupivacaine inhibited TREK-1 channels and depolarized the membrane potential of cells expressing TREK-1 channels in a concentration-dependent and reversible manner. Both effects may contribute to conductance block caused by bupivacaine.

The Effects of Enflurane, Isoflurane, and Intravenous Anesthetics on Rat Diaphragmatic Function and Fatigability
Anesth Analg 2003 96: 1674-1678. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Enflurane did not change contraction or relaxation in fresh isolated rat diaphragm, but enhanced diaphragmatic fatigability itself and fatigue-induced impairment of twitch characteristics and tetanic tensions. Isoflurane, midazolam, ketamine, propofol, and thiopental had no direct effects on diaphragmatic functions under unfatigued and fatigued conditions. Isoflurane and these IV anesthetics may be advantageous over enflurane to anesthetize and/or sedate patients who are predisposed to diaphragmatic fatigue.

Resistive-Heating and Forced-Air Warming Are Comparably Effective
Anesth Analg 2003 96: 1683-1687. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Efficacy was similar for forced-air and resistive heating, and both maintained intraoperative core temperature far better than circulating-water mattresses. We thus conclude that even during major abdominal surgery, resistive heating maintains core temperature as effectively as forced air.

The Effect of Hypothermia on Myogenic Motor-Evoked Potentials to Electrical Stimulation with a Single Pulse and a Train of Pulses Under Propofol/Ketamine/Fentanyl Anesthesia in Rabbits
Anesth Analg 2003 96: 1692-1697. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Intraoperative monitoring of myogenic motor-evoked potentials (MEPs) may be required under hypothermic conditions because of its neuroprotective efficacy. However, data on the influence of hypothermia on myogenic MEPs are limited. The results indicate that multipulse stimulation may be better than single-pulse stimulation when monitoring MEPs during hypothermia.

The Effect of Systemic Zonisamide (Zonegran^TM) on Thermal Hyperalgesia and Mechanical Allodynia in Rats with an Experimental Mononeuropathy
Anesth Analg 2003 96: 1700-1706. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Zonisamide causes a dose-related decrease in heat sensitivity in a rat model of neuropathic pain, but relieves mechanical sensitivity only in a dose that is sedating to the rat. Zonisamide may be useful in the treatment of some types of neuropathic pain.

Antinociceptive Potentiation and Attenuation of Tolerance by Intrathecal Electric Stimulation in Rats
Anesth Analg 2003 96: 1711-1716. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Control of chronic pain is a major health problem. We show here that direct electrical stimulation of the spinal cord in rats enhances analgesia and attenuates naloxone-induced withdrawal symptoms. This may warrant further investigation in the context of long-term use of intrathecal opioids for controlling chronic pain.

Prone Position Improves Lung Mechanical Behavior and Enhances Gas Exchange Efficiency in Mechanically Ventilated Chronic Obstructive Pulmonary Disease Patients
Anesth Analg 2003 96: 1756-1767. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: By assessing respiratory mechanics, inspiratory work, hemodynamics, and gas exchange, we showed that prone positioning of mechanically ventilated chronic obstructed pulmonary disease patients improves oxygenation and lung mechanics during sigh versus semirecumbent positioning. Furthermore, certain pronation-related benefits versus preprone-supine positioning (reduced lung elastance and improved oxygenation) are maintained in the postprone supine position.

The Numeric Rating Scale and Labor Epidural Analgesia
Anesth Analg 2003 96: 1794-1798. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: This study demonstrated that unless the score of the verbal numeric 0-10 rating scale (NRS) is 0 or 1, most women want more analgesic medication for labor epidural analgesia. Additionally, we found that grouping the NRS values into 3 categories for analysis (0 or 1, 2 or 3, and > 3) is more useful to the clinician than using the full spectrum of NRS scores.

Postdural Puncture Headache: An Imaging-Guided Management Protocol (Case Report)
Anesth Analg 2003 96: 1809-1812. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We propose an imaging-based algorithm for the management of headache caused by the inadvertent puncture of dura that occurs sporadically during epidural analgesia. Its implementation can identify those postdural puncture headache cases that cannot benefit from epidural blood patches, and their unnecessary application can consequently be avoided.

Does Lead Interfere with Hemoglobin-Based Oxygen Carrier (HBOC) Function? A Pilot Study of Lead Concentrations in Three Approved or Tested HBOCs and Oxyhemoglobin Dissociation with HBOCs and/or Bovine Blood with Varying Lead Concentrations
Anesth Analg 2003 96: 1813-1820. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Gunshot wounds rapidly increase circulating lead concentrations. Lead concentrations are small in three hemoglobin-based oxygen carriers (HBOCs), and HBOCs and/or bovine blood do not appear to be affected by lead concentrations in terms of immediate oxygen on-loading and off-loading. HBOCs may be useful in patients with gunshot wounds.

Storage Capacities of the Laryngeal Mask and Laryngeal Tube Compared and Their Relevance to Aspiration Risk During Positive Pressure Ventilation (Brief Report)
Anesth Analg 2003 96: 1821-1822. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Supraglottic airways used for positive pressure ventilation run the occasional risk of regurgitated liquid entering the lungs (aspiration). A dynamic model described here shows that the laryngeal tube has a larger liquid storage capacity between the two cuffs than the bowl of the laryngeal mask, with a consequent smaller aspiration risk.
