Randomized Controlled Trial Comparative Study Clinical Trial
Adjuvant bupivacaine scalp block facilitates stabilization of hemodynamics in patients undergoing craniotomy with general anesthesia: a preliminary report.
To evaluate the effect of 0.25% bupivacaine scalp block on alterations in hemodynamics and plasma catecholamine metabolites during general anesthesia in patients undergoing frontotemporal craniotomy. ⋯ Pretreatment with 0.25% bupivacaine scalp block appeared to be an effective adjuvant treatment for maintaining stable hemodynamics for patients undergoing craniotomy during general anesthesia especially at the time of skin incision and dural opening. This study design was unable to discern any correlation between elevation in hemodynamic parameters and a rise in serum catecholamine levels.

Randomized Controlled Trial Comparative Study Clinical Trial
Gender differences between predicted and measured propofol C(P50) for loss of consciousness.
To investigate gender differences in the effective dose of 50% for loss of consciousness (C(P50LOC)) for propofol using Diprifusor, the most commonly used target-controlled infusion system. ⋯ Predicted C(P50LOC) by Diprifusor for men tended to be underestimated; that for women tended to be overestimated. Our data support a review of Diprifusor (Astra Zeneca, Osaka, Japan) pharmacokinetic parameters to avoid awareness during operation, particularly for women.

Randomized Controlled Trial Comparative Study
Influence of aging on lidocaine requirements for pain on injection of propofol.
To evaluate the influence of aging on lidocaine requirements for propofol-induced pain on injection. ⋯ A lidocaine dose of 40 mg for young patients and 20 mg for old patients, with venous occlusion for two minutes, is sufficient to reduce pain on injection of propofol.

Randomized Controlled Trial
Concurrent expansion of plasma volume and left ventricular end-diastolic volume in patients after rapid infusion of 5% albumin and lactated Ringer's solution.
To examine the effects of plasma volume expansion on plasma volume, left ventricular end-diastolic volume (LVEDV), and cardiac index (CI) after rapid fluid infusion, as knowledge of the degree of concordance between plasma and cardiac preload expansion could optimize LVEDV expansion without administering excessive fluid. ⋯ Intravenous fluids increased LVEDV to a lesser extent and duration than did plasma volume expansion. Monitoring of LVEDV was a poor guide for fluid administration to maximize CI.

Multicenter Study
Patient perception of the role of anesthesiologists: a perspective from the Caribbean.
To assess patients' perception of the role of an anesthesiologist in a Caribbean country. ⋯ Patients still have inadequate knowledge regarding anesthesiologists and their different roles in hospitals.
