Plasma Aprotinin Concentrations During Cardiac Surgery: Full- Versus Half-Dose Regimens
Anesth Analg 2000 91: 257-264. [Abstract] [Full Text]  

Implications: The current dosing schedule for aprotinin results in a large variation in aprotinin plasma concentrations among patients and a large variation within each patient over time. We combined the information provided by our study with that of a previous pharmacokinetic study to develop a potentially improved, weight-based, dosing regime for aprotinin.

Congenital Tracheal Bronchus: The Inability to Isolate the Right Lung with a Univent Bronchial Blocker Tube (Case Report)
Anesth Analg 2000 91: 300-301. [Abstract] [Full Text]  

Implications: Tracheal bronchus is a congenital anomaly in whichthe right upper lobe bronchus originates from the lateral trachealwall. This anatomic variant is reported in approximately 1 of250 patients at bronchoscopy. Although it is usually of littleclinical significance, this atypical origin of the right upperlobe bronchus may complicate one-lung ventilation during thoracicsurgery.

Postoperative Death and Malpractice Suits: Is Autopsy Useful? (Brief Report)
Anesth Analg 2000 91: 344-346. [Abstract] [Full Text]  

Implications: This report demonstrates the extremely high yieldof autopsies performed in the case of postoperative death withsuspicion of malpractice. They frequently identified undetectedcomplications. They could also suggest faulty or negligent practicethat would otherwise go unrecognized. This report supports thewidespread use of autopsies to investigate perioperative death.

A Correlation Between Dexmedetomidine-Induced Biphasic Increases in Free Cytosolic Calcium Concentration and Energy Metabolism in Astrocytes
Anesth Analg 2000 91: 353-357. [Abstract] [Full Text]  

Implications: Cytosolic calcium concentration and metabolismwere measured in cultured astrocytes, the predominant glialcells. The results suggest that dexmedetomidine may owe itsanesthetic effects to a Ca2+-dependent increase in astrocyticenergy metabolism, allowing these cells to more effectivelyremove extracellular glutamate and potassium ions, and thus,decreasing neuronal excitability.

A Randomized, Double-Blinded Comparison of Ondansetron, Droperidol, and Placebo for Prevention of Postoperative Nausea and Vomiting After Supratentorial Craniotomy
Anesth Analg 2000 91: 358-361. [Abstract] [Full Text]  

Implications: Nausea and vomiting after brain surgery are particularlytroubling, because effective treatment may cause sedation, makingpostoperative neurological assessment difficult. Our study showsthat both ondansetron and droperidol are effective in reducingnausea, and that droperidol is particularly effective in reducingvomiting. Neither drug caused more sedation than placebo.

Concentrations of Lidocaine and Monoethylglycine Xylidide in Brain, Cerebrospinal Fluid, and Plasma During Lidocaine-Induced Epileptiform Electroencephalogram Activity in Rabbits: The Effects of Epinephrine and Hypocapnia
Anesth Analg 2000 91: 362-368. [Abstract] [Full Text]  

Implications: Hypocapnia increases the toxic dose of lidocainegiven IV without altering lidocaine concentrations in blood,brain, or cerebrospinal fluid. Whole-brain monoethylglycinexylidide concentration is greater during hypocapnia than duringnormocapnia, and the addition of epinephrine to lidocaine increasesthe concentration of monoethylglycine xylidide in plasma.

OBSTETRIC ANESTHESIA:

Informed Consent for Obstetric Anesthesia Research: Factors that Influence Parturients’ Decisions to Participate
Anesth Analg 2000 91: 369-373. [Abstract] [Full Text]  

Implications: Obtaining informed consent for obstetric anesthesiastudies presents a challenge to the anesthesiologist. Resultsfrom this study suggest that the environment in which consentfor obstetric studies is sought is not coercive. However, itis important that the anesthesiologist ensures that the patientfully understands the study and develops a rapport with thepatient to allay any anxiety associated with her participationas a potential research subject.

The Current Perception Thresholds Vary Between Horizontal and 70° Tilt-Up Positions
Anesth Analg 2000 91: 398-402. [Abstract] [Full Text]  

Implications: Current perception thresholds at the 70{degrees} tilt-upposture were significantly lower than those at the horizontalposture. When the compensatory mechanism for preserving bloodpressure was emphasized, the current perception thresholds wouldhave a relational connection to mean systolic blood pressure,similar to the concept of hypertension-induced hypoalgesia.

Preventing Postoperative Pain by Local Anesthetic Instillation After Laparoscopic Gynecologic Surgery: A Placebo-Controlled Comparison of Bupivacaine and Ropivacaine
Anesth Analg 2000 91: 403-407. [Abstract] [Full Text]  

Implications: Local anesthetic instillation (ropivacaine ratherthan bupivacaine) at the end of laparoscopy prevents postoperativepain and dramatically decreases the need for morphine. Thistechnique, compared with placebo, is safe, improves patientcomfort, shortens the stay in the postoperative care unit anddecreases nursing care in the ward.

The Superiority of Water-Diluted 0.25% to Neat 1% Lidocaine for Trigger-Point Injections in Myofascial Pain Syndrome: A Prospective, Randomized, Double-Blinded Trial (Brief Report)
Anesth Analg 2000 91: 408-409. [Abstract] [Full Text]  

Implications: Trigger-point injection with a mixture of commerciallyavailable 1% lidocaine in sterile distilled water at a ratioof 1:3 compared with 1% lidocaine alone resulted in better efficacyand less injection pain. This simple procedure may be suitablefor treatments of a wide range of myofascial pain syndromes.

The Addition of Dilute Epinephrine Produces Equieffectiveness of Bupivacaine Enantiomers for Cutaneous Analgesia in the Rat (Brief Report)
Anesth Analg 2000 91: 410-416. [Abstract] [Full Text]  

Implications: Here we show that the more potent optical R-isomerof bupivacaine (Bup) can be used at a smaller dose (80%) thanthe S-isomer of Bup to give equal pain relief of a skin prick.Although the analgesia from R-Bup is briefer than that fromequipotent S-Bup solutions, the durations become equal whena very dilute solution of the vasoconstrictor epinephrine ismixed with the R-isomer. The resulting vasoconstriction thusreduces vascular drug uptake and peak blood levels of systemicdrug, reducing potential toxicity.

The Effect of Spinal Ibuprofen on Opioid Withdrawal in the Rat (Brief Report)
Anesth Analg 2000 91: 417-422. [Abstract] [Full Text]  

Implications: This study shows that spinal ibuprofen blocksopioid withdrawal hyperalgesia in the rat in a stereospecificfashion, implicating the likely release of spinal prostaglandinsduring withdrawal and their possible role as neuromodulatorsin the enhancement of nociception that accompanies this phenomenon.

Compound A Concentrations During Low-Flow Sevoflurane Anesthesia Correlate Directly with the Concentration of Monovalent Bases in Carbon Dioxide Absorbents
Anesth Analg 2000 91: 434-439. [Abstract] [Full Text]  

Implications: Sevoflurane degradation to Compound A is decreasedby lowering the concentration of monovalent bases in the carbondioxide absorbent (Dragersorb 800 Plus(R) [Drager,Luebeck, Germany] and Medisorb(R) [Datex-Ohmeda, Bromma, Sweden])and is virtually eliminated in the absence of these bases (Amsorb(R)[Armstrong Medical, Coleraine, Northern Ireland]).

Sevoflurane Stimulates Inositol 1,4,5-Trisphosphate in Skeletal Muscle
Anesth Analg 2000 91: 440-445. [Abstract] [Full Text]  

Implications: Inhaled anesthetics increase intracellular ionizedcalcium in the skeletal muscle cell and the ionized calciumincrease is partly released from the intracellular store byinositol 1,4,5-triphosphate (IP3) formation. IP3 plays an importantrole in excitation-contraction coupling and malignant hyperthermia.We studied whether sevoflurane affects IP3 formation and themechanisms that modulate IP3.

Absorption of Carbon Dioxide by Dry Soda Lime Decreases Carbon Monoxide Formation from Isoflurane Degradation
Anesth Analg 2000 91: 446-451. [Abstract] [Full Text]  

Implications: We determined, in vitro, that carbon monoxide(CO) formation from isoflurane by dry soda lime is reduced bycarbon dioxide (CO2). We believe that the potential for injuryfrom CO is less in the clinical milieu than suggested by datafrom experiments without CO2 because of an interdependence betweenCO formation and CO2 absorption.

Between-Center Variability of Results of the In Vitro Contracture Test for Malignant Hyperthermia Susceptibility
Anesth Analg 2000 91: 452-457. [Abstract] [Full Text]  

Implications: The diagnostic outcomes of tests for malignanthyperthermia susceptibility were compared between two laboratoriesby using muscle tissue from the same patients. Identical outcomeswere found for 56% of the patients. Almost all diverging outcomeswere seen in cases with a few small contractures near the cutofflimit. Different diagnostic criteria for clinical and scientificpurposes are suggested.

Inhaled Anesthetics Have Hyperalgesic Effects at 0.1 Minimum Alveolar Anesthetic Concentration
Anesth Analg 2000 91: 462-466. [Abstract] [Full Text]  

Implications: The inhaled anesthetics isoflurane, halothane,nitrous oxide, and diethyl ether produce antianalgesia at subanestheticconcentrations, with a maximal effect at approximately one-tenththe concentration required for anesthesia. This effect may enhanceperception of pain when such small concentrations are reachedduring recovery from anesthesia.
