Preoperative Intravenous Fluid Therapy Decreases Postoperative Nausea and Pain in High Risk Patients
Anesth Analg 2005 100: 675-682. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Intensive preoperative IV rehydration reduces the incidence and severity of postoperative nausea and vomiting (PONV) in high risk patients undergoing ambulatory surgery. This prospective, randomized, controlled, double-blind clinical trial demonstrates that perioperative hydration with a balanced salt solution at 2 mL/kg per hour of fasting effectively reduces PONV and postoperative pain in high risk patients undergoing gynecologic laparoscopy.

Bacteriostatic Saline Containing Benzyl Alcohol Decreases the Pain Associated with the Injection of Propofol (Brief Report)
Anesth Analg 2005 100: 683-686. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We studied the effect of preinjection with bacteriostatic saline, an agent with known anesthetic properties, on the incidence of pain associated with the IV injection of propofol. We found that it decreases the incidence and severity of pain, and the decrease is comparable to that of mixing lidocaine with propofol.

Dexmedetomidine Decreases the Convulsive Potency of Bupivacaine and Levobupivacaine in Rats: Involvement of ₂-Adrenoceptor for Controlling Convulsions
Anesth Analg 2005 100: 687-696. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Dexmedetomidine decreased the convulsive potency of racemic bupivacaine and levobupivacaine by increasing their convulsive dose and plasma and brain concentrations at the onset of convulsions. Because this anticonvulsant effect was antagonized by yohimbine, an {alpha}2-adrenoceptor antagonist, dexmedetomidine would exert its anticonvulsant effect via the {alpha}2-adrenoceptor.

Cutaneous Heat Loss with Three Surgical Drapes, One Impervious to Moisture
Anesth Analg 2005 100: 738-742. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Our results indicate that heat loss from dry or wet skin is comparable when subjects are covered with a new surgical drape impervious to fluid (Tiburon) and when they are covered with conventional surgical drapes. Hypothermia or hyperthermia is thus no more likely to occur when using the Tiburon than conventional drapes.

The Influence of Trauma and Ischemia on Carbohydrate Metabolites Monitored in Hamster Flap Tissue
Anesth Analg 2005 100: 817-822. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: In a hamster skin flap model we demonstrated that in traumatized tissue, lactate/pyruvate ratio is more appropriate than lactate to detect ischemic hypoxia. However, both markers may be increased as a result of trauma itself. This markedly reduces their specificity to detect ischemic hypoxia in the presence of trauma.

Sepsis Stage Dependently and Differentially Attenuates the Effects of Nondepolarizing Neuromuscular Blockers on the Rat Diaphragm In Vitro
Anesth Analg 2005 100: 823-829. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: We demonstrated by in vitro experiments with septic rats that sepsis stage-dependently and differentially attenuates the actions of nondepolarizing neuromuscular blockers. Late sepsis more intensely attenuates the actions than does early sepsis. The sepsis-induced attenuations were largest for pancuronium, second largest for rocuronium, and smallest for d-tubocurarine.

The Effects of Propofol or Sevoflurane on the Estimated Cerebral Perfusion Pressure and Zero Flow Pressure
Anesth Analg 2005 100: 835-840. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Propofol significantly increases, and sevoflurane significantly decreases cerebral vascular tone as assessed by changes in zero flow pressure. Thus, despite moderate decreases in mean arterial blood pressure, the estimated cerebral perfusion pressure is preserved during sevoflurane, but not during propofol anesthesia.

Anesth Analg 2005 100: 855-865. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The overall incidence of cardiac arrest during spinal or epidural anesthesia was 1.8 per 10,000 blocks between 1988 and 2002. Patients who experienced a cardiac arrest during neuraxial anesthesia had an equal or greater likelihood of survival than those who arrested during general anesthesia.

Adding Clonidine to the Induction Bolus and Postoperative Infusion During Continuous Femoral Nerve Block Delays Recovery of Motor Function After Total Knee Arthroplasty
Anesth Analg 2005 100: 866-872. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: The addition of clonidine 1 {micro}g/kg in the initial bolus followed by clonidine 1 {micro}g/mL in the postoperative infusion during continuous femoral nerve block after total knee arthroplasty does not provide clinically relevant advantages in terms of improving postoperative analgesia, but it potentially delays the recovery of motor function.

Capnogram Shape in Obstructive Lung Disease
Anesth Analg 2005 100: 884-888. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: Capnogram shape was used to separate obstructive lung disease subjects from normals and subjects with restrictive lung disease. Changes in the capnogram shape correlated with changes in spirometry. This suggests that the capnogram may be useful as a noneffort-dependent method for distinguishing obstructive subjects from normals.

Peak Airway Pressure Increase Is a Late Warning Sign of Partial Endotracheal Tube Obstruction Whereas Change in Expiratory Flow Is an Early Warning Sign
Anesth Analg 2005 100: 889-893. [Abstract] [Full Text] [PDF] [Request Permissions]  

IMPLICATIONS: With low inspiratory flow (V) rates, peak inspiratory airway pressure may fail to indicate progressive obstruction of the endotracheal tube. The decelerating effect of endotracheal tube narrowing on expiratory V, by contrast, can easily and reliably be recognized on the expiratory V-volume plot, making expiratory Vanalysis a helpful monitoring tool.
