Randomized Controlled Trial Comparative Study Clinical Trial
Effects of nicardipine-, nitroglycerin-, and prostaglandin E1-induced hypotension on human cerebrovascular carbon dioxide reactivity during propofol-fentanyl anesthesia.
To investigate the effects of nicardipine-, nitroglycerin-, and prostaglandine E1-induced hypotension on cerebrovascular carbon dioxide (CO2) reactivity over a wide range of arterial CO2 tension (PaCO2) (PaCO2; range 25 to 50 mmHg). ⋯ Nicardipine-, nitroglycerin-, and prostaglandin E1-induced hypotension attenuate the human cerebrovascular CO2 reactivity during propofol-fentanyl anesthesia.

Randomized Controlled Trial Clinical Trial
Influence of the priming technique on pharmacodynamics and intubating conditions of cisatracurium.
To determine the effects of the priming technique on the intubating conditions and pharmacodynamics of different doses of cisatracurium. ⋯ When primed, cisatracurium 0.09 mg/kg and 0.14 mg/kg produced an onset time comparable with that of 0.2 mg/kg and allowed an earlier spontaneous recovery (p < 0.05). In this study, there was no benefit in priming cisatracurium 0.19 mg/kg.

Randomized Controlled Trial Clinical Trial
Isoflurane, nitrous oxide, and fentanyl pharmacodynamic interactions in surgical patients as measured by effects on median power frequency.
To identify and quantify the simultaneous interactions of isoflurane, nitrous oxide (N2O), and fentanyl during surgical procedures. The slowing of the EEG to a median power frequency of 2 Hz to 3 Hz was chosen as the measure of pharmacodynamic drug effect. ⋯ The potency of N2O and fentanyl to substitute isoflurane in maintaining a median power frequency of 2 Hz to 3 Hz during surgery is less than anticipated from minimum alveolar concentration studies.

Case Reports
Entrapment of an exchange wire by an inferior vena caval filter: a technique for removal.
The anesthesiology literature does not describe entrapment of a guidewire by an inferior vena caval filter. Because anesthesiologists are involved in central access in various perioperative and intraoperative settings, consideration of this complication is important. A case of guidewire entrapment by an inferior vena caval filter and a unique technique for removal of the entrapped wire is presented.
