The Impact of Postoperative Discontinuation or Continuation of Chronic Statin Therapy on Cardiac Outcome After Major Vascular Surgery
Anesth Analg 2007 104: 1326-1333. [Abstract] [Full Text] [PDF] [CME]  

IMPLICATIONS: We retrospectively examined the frequency of cardiac myonecrosis (troponin I release >0.2 ng/mL) in patients who had either statin therapy discontinued or resumed immediately after major vascular surgery. Discontinuation of statin therapy was associated with an increased postoperative cardiac risk, suggesting that statin therapy should be resumed early after major vascular surgery.

Coagulopathy After Cardiac Surgery May Be Influenced by a Functional Plasminogen Activator Inhibitor Polymorphism
Anesth Analg 2007 104: 1343-1347. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: In this observational study of elective cardiac surgery patients we demonstrate a consistent decrease in plasminogen activator inhibitor-1 (PAI-1) mRNA production after cardiopulmonary bypass. The extent of the decrease was related to PAI-1 genotype. In addition, we describe an association between PAI-1 4G/5G genotype and a propensity to receive coagulation blood products early after cardiac surgery.

The Effects of Jaw Thrust and the Lateral Position on Heart Rate Variability in Anesthetized Children with Obstructive Sleep Apnea Syndrome
Anesth Analg 2007 104: 1352-1355. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: In children with obstructive sleep apnea syndrome, in the neutral neck position, anesthesia induced an occluded airway and changed heart rate variability (HRV). Relief of the occluded airway by jaw thrust and lateral positioning returned HRV to preanesthetic levels. These changes in HRV paralleled the improved stridor scores.

The Impact of Positive End-Expiratory Pressure on Functional Residual Capacity and Ventilation Homogeneity Impairment in Anesthetized Children Exposed to High Levels of Inspired Oxygen
Anesth Analg 2007 104: 1364-1368. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Functional residual capacity (FRC) and ventilation distribution decreased significantly at a fraction of inspired oxygen (Fio2) of 1.0 compared with an Fio2 of 0.3 when children were ventilated with a very low positive end-expiratory pressure (PEEP) of 3-cm H2O. These changes in FRC and ventilation distribution were prevented by the continuous administration of PEEP of 6-cm H2O.

An Evaluation of a Single Dose of Magnesium to Supplement Analgesia After Ambulatory Surgery: Randomized Controlled Trial
Anesth Analg 2007 104: 1374-1379. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: In a randomized, placebo-controlled, double-blind trial, an IV bolus of magnesium sulfate 4 g, administered after anesthetic induction in patients undergoing ambulatory ilioinguinal hernia repair or varicose vein operations under general anesthesia, had no impact on postoperative pain and analgesic consumption.

The Role of the Anesthesiologist in Fast-Track Surgery: From Multimodal Analgesia to Perioperative Medical Care (Special Article)
Anesth Analg 2007 104: 1380-1396. [Abstract] [Full Text] [PDF] [CME]  

IMPLICATIONS: The pivotal role of the anesthesiologist as the key perioperative physician in facilitating the recovery process has assumed increased importance in the current fast-track recovery environment. The choice of premedication, anesthetic, analgesic and antiemetic drugs, as well as cardiovascular, hormonal, and fluid therapies, can influence the ability to fast-track patients after elective surgery.

Modulation of Remifentanil-Induced Postinfusion Hyperalgesia by Propofol
Anesth Analg 2007 104: 1397-1403. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Brief opioid exposure can enhance pain sensitivity. We investigated subhypnotic concentrations of propofol on remifentanil-induced hypersensitivity in an experimental human pain model. Propofol delayed and decreased, but did not completely antagonize, remifentanil-induced anti-analgesia. This may explain the increased demand for analgesics after remifentanil-based anesthesia.

Morphine Metabolism After Major Liver Surgery
Anesth Analg 2007 104: 1409-1414. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This study demonstrates that patients undergoing major liver surgery have a decreased morphine clearance. The impaired morphine metabolism is associated with an increased incidence of sedation.

Riluzole, a Glutamate Release Inhibitor, Induces Loss of Righting Reflex, Antinociception, and Immobility in Response to Noxious Stimulation in Mice
Anesth Analg 2007 104: 1415-1421. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Glutamatergic neurons are important targets for anesthetic action. We examined the ability of riluzole, which inhibits glutamate release from nerve terminals, to produce components of the anesthetic state. Our findings suggest that riluzole-induced loss of consciousness, immobility, and antinociception are associated with inhibition of glutamatergic neurotransmission in the central nervous system.

Increased -Aminobutyric Acid Levels in Mouse Brain Induce Loss of Righting Reflex, but Not Immobility, in Response to Noxious Stimulation
Anesth Analg 2007 104: 1422-1429. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The functional relevance of {gamma}-aminobutyric acid (GABA)-ergic inhibitory neurotransmission in mediating essential components of anesthesia is unknown. We examined the ability of increased GABA levels to produce behavioral components of anesthesia. Our findings suggest that unconsciousness and immobility are mediated through different neuronal pathways and/or regions in the central nervous system.

The Effects of the Local Anesthetics Lidocaine and Procaine on Glycine and -Aminobutyric Acid Receptors Expressed in Xenopus Oocytes
Anesth Analg 2007 104: 1434-1439. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Lidocaine and procaine enhanced glycine receptor function at low concentrations and inhibited glycine and {gamma}-aminobutyric acid type A receptors functions at high concentrations. The mechanism of the local anesthetic (LA)-induced enhancement of glycine receptor function probably differs from that of general anesthetics. These findings may explain the pharmacological effects of LAs, such as antinociception and convulsion.

A Comparison of Pharmacokinetic/Pharmacodynamic versus Mass-Balance Measurement of Brain Concentrations of Intravenous Anesthetics in Sheep
Anesth Analg 2007 104: 1440-1446. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Accurate estimates of t1/2Keo are critical for effect-compartment dosing in IV anesthesia. We compared the pharmacokinetic/pharmacodynamic and mass-balance methods for propofol, methohexital, and ketamine in a sheep model. Both methods give similar values for t1/2Keo. Methohexital crosses into the brain much faster than either propofol or ketamine.

Sevoflurane: Are There Differences in Products? (Medical Intelligence)
Anesth Analg 2007 104: 1447-1451. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Although the two sevoflurane products available in the United States are rated therapeutically equivalent, there are differences in the manufacturing processes between Ultane(R) and generic sevoflurane. They are also packaged in different containers. The quantities of impurities are, however, low and qualitative differences minor and unlikely to be of clinical significance.

Desflurane Hepatitis Associated with Hapten and Autoantigen-Specific IgG4 Antibodies (Case Report)
Anesth Analg 2007 104: 1452-1453. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We provide the first documentation of cytochrome P450 2E1 IgG4 autoantibodies, as well as 58 kDa endoplasmic reticulum protein and trifluoroacetyl chloride hapten-specific IgG4 antibodies, in a patient who developed hepatitis after desflurane anesthesia. These findings suggest that allergic and autoimmune mechanisms have critical roles in the development of desflurane-induced liver injury.

Significant Hypoglycemia Secondary to Icodextrin Peritoneal Dialysate in a Diabetic Patient (Case Report)
Anesth Analg 2007 104: 1473-1474. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Icodextrin, a peritoneal dialysate commonly used in the renal failure patient with diabetes, may lead to an overestimation of blood glucose levels as determined by bedside glucometers. Failure to communicate this information to all caregivers may lead to inappropriate treatment and patient mortality.

Electrocerebral Silence After Intracarotid Propofol Injection Is a Function of Transit Time
Anesth Analg 2007 104: 1498-1503. [Abstract] [Full Text] [PDF] [Videos]   

IMPLICATIONS: The duration of electrocerebral silence after intracarotid bolus injection of propofol during cerebral hypoperfusion was related to the transit time of the propofol emulsion. In the cerebral circulation, the effects of highly lipid-soluble drugs are a function of the time available for the drug to diffuse across the blood brain barrier.

Magnesium as an Adjuvant to Postoperative Analgesia: A Systematic Review of Randomized Trials
Anesth Analg 2007 104: 1532-1539. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Systematically searched randomized trials do not provide convincing evidence that perioperative magnesium may have favorable effects on postoperative pain intensity and analgesic requirements. Perioperative magnesium supplementation prevents postoperative hypomagnesemia and decreases the incidence of postoperative shivering.

Multimodal Analgesia to Prevent Propofol-Induced Pain: Pretreatment with Remifentanil and Lidocaine Versus Remifentanil or Lidocaine Alone
Anesth Analg 2007 104: 1540-1544. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This prospective, randomized, double-blind study evaluated the incidence and severity of propofol injection pain after pretreatment with remifentanil, premixing propofol with lidocaine, or the combination of both. The combination of remifentanil and lidocaine significantly reduced the incidence of mild pain and completely abolished moderate and severe pain as compared to either drug alone.

Do Surgical Patients Benefit from Perioperative Gabapentin/Pregabalin? A Systematic Review of Efficacy and Safety
Anesth Analg 2007 104: 1545-1556. [Abstract] [Full Text] [PDF] [Data Supplement]   

IMPLICATIONS: This systematic review shows that preoperative administration of gabapentin/pregabalin reduces postoperative pain intensity, opioid consumption, and opioid-related adverse effects without major risks. Studies defining optimal dosing, duration of the treatment, and effects on chronic pain are needed.

Ten Consecutive Cases of Complex Regional Pain Syndrome of Less than 12 Months Duration in Active Duty United States Military Personnel Treated with Spinal Cord Stimulation (Case Report)
Anesth Analg 2007 104: 1557-1560. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Spinal cord stimulation for refractory complex regional pain syndrome of less than 1 yr duration may be effective as measured by decreased opioid intake, participation with physical rehabilitation, and retention on active military duty. These observations should be interpreted cautiously based on the short duration of postimplantation follow-up and the small number of cases presented.

Experimental Neuropathy in Mice Is Associated with Delayed Behavioral Changes Related to Anxiety and Depression
Anesth Analg 2007 104: 1570-1577. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Patients with chronic pain frequently suffer affective disorders. To study the relationship between pain and affective disorders, we examined anxiety and depression-related behaviors in mice subjected to spinal nerve ligation. Nerve injury can trigger affective disturbances in mice that appear much later than sensory hypersensitivity.

Epidural Anesthesia and Analgesia Decrease the Postoperative Incidence of Insulin Resistance in Preoperative Insulin-Resistant Subjects Only
Anesth Analg 2007 104: 1587-1593. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Insulin resistance is a feature of the endocrine stress response to surgery. In this study, epidural anesthesia and analgesia, compared with general anesthesia and patient-controlled analgesia, decreased the incidence of insulin resistance immediately after surgery and 48 h postoperatively in patients who were insulin-resistant before surgery.
