Randomized Controlled Trial Comparative StudyInfluence of low-molecular-weight hydroxyethyl starch on microvascular permeability in patients undergoing abdominal surgery: comparison with crystalloid.
Adequate volume therapy is essential for stable hemodynamics and sufficient urinary output perioperatively. Hydroxyethyl starch (HES) has been reported to attenuate the microvascular hyperpermeability which occasionally occurs in surgical patients. This study was carried out to evaluate the effect of low-molecular-weight HES on the urinary microalbumin/creatinine ratio (MACR), a marker of microvascular permeability, in surgical patients. ⋯ Although low-molecular-weight HES does not improve microvascular hyperpermeability, the expansion of the intravascular volume by HES results in higher urinary output in the postoperative period than that seen with crystalloid solution. The lower concentration of sICAM-1 after surgery may be due to hemodilution.

Randomized Controlled TrialEffects of landiolol on the cardiovascular response during tracheal extubation.
The objective of this study was to investigate the effect of landiolol on the cardiovascular responses to emergence from anesthesia and tracheal extubation. Fifty-nine patients without cardiovascular disorders who were scheduled for tympanoplasty were randomly allocated to receive a loading dose of landiolol at 0.125 mg x kg(-1) x min(-1) for 1 min, followed by an infusion at 0.01 mg x kg(-1) x min(-1) (group L1), 0.02 mg x kg(-1) x min(-1) (group L2), 0.03 mg x kg(-1) x min(-1) (group L3), or 0.04 mg x kg(-1) x min(-1) (group L4). ⋯ Just after extubation compared with the baseline, the MAP increased significantly in all groups; the HR increased in groups L1 and L2; and the RPP increased in all groups, except for group L4. Continuous administration of landiolol, at 0.03 or 0.04 mg x kg(-1) x min(-1), may prevent the increases in HR and RPP, respectively, that occur at the emergence from anesthesia and tracheal extubation.

Randomized Controlled Trial Comparative StudyThe comparative effects of sevoflurane versus isoflurane on cerebrovascular carbon dioxide reactivity in patients with previous stroke.
The use of volatile anesthetics is reportedly related to altered cerebrovascular carbon dioxide (CO2) reactivity. We examined the comparative effects of sevoflurane versus isoflurane on cerebrovascular CO2 reactivity in patients with previous stroke. ⋯ Our findings suggest that, in patients with previous stroke, cerebrovascular CO2 reactivity under sevoflurane anesthesia was lower than that under isoflurane anesthesia.

Randomized Controlled TrialAdding intrathecal morphine to unilateral spinal anesthesia results in better pain relief following knee arthroscopy.
Intrathecal morphine is administered to provide profound and prolonged analgesia, and to treat acute postoperative pain. We compared the effectiveness of hyperbaric bupivacaine alone and in combination with morphine for unilateral spinal anesthesia in patients undergoing knee arthroscopy. ⋯ We conclude that unilateral spinal anesthesia with hyperbaric bupivacaine plus 0.16 mg morphine is preferable to hyperbaric bupivacaine alone with respect to analgesic requirement, duration of analgesia, and VAS values.
