Randomized Controlled Trial Clinical TrialThe effects of hydroxyethyl starch solutions on thromboelastography in preoperative male patients.
Hydroxyethyl starches (HES) have been shown to decrease clot strength and to increase coagulation times assessed by thromboelastography (TEG). HES with minimal anticoagulant side-effects is beneficial for plasma volume expansion in the perioperative setting. A comparison of the in vivo effects of high, middle and low molecular weight HES solutions on TEG variables has not been performed so far. ⋯ Infusion of HES 450/0.7/4.6 compromises TEG parameters more than the other solutions tested, whereas HES 130/0.4/9 has the smallest effect. Further outcome-related studies are needed in order to assess the clinical relevance of our findings.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the catheter-technique psoas compartment block and the epidural block for analgesia in partial hip replacement surgery.
The aim of this study was to compare the intra- and postoperative analgesia provided by the catheter-technique psoas compartment block and the epidural block in hip-fractured patients. We also compared hemodynamic stability, motor blockade, ease of performing the technique, and complications. ⋯ The continuous psoas compartment block provides excellent intraoperative and postoperative analgesia with a low incidence of complications for partial hip replacement surgery

Randomized Controlled Trial Comparative Study Clinical TrialComparison of epidural, continuous femoral block and intraarticular analgesia after anterior cruciate ligament reconstruction.
The purpose of this study was to compare three locoregional techniques of pain management after arthroscopic anterior cruciate ligament reconstruction (ACLR). ⋯ We conclude that either epidural or continuous femoral nerve block provide adequate pain relief in patients who undergo ACLR, whereas intraarticular analgesia seems unable to cope satisfactorily with the analgesic requirements of this surgical procedure.

Randomized Controlled Trial Clinical TrialClinical trial of esmolol-induced controlled hypotension with or without acute normovolemic hemodilution in spinal surgery.
Drug-induced controlled hypotension (CH) combined with acute normovolemic hemodilution (ANH) is being widely used for blood conservation in surgical patients. The purpose of this study was to investigate the efficacy and safety of esmolol-induced CH combined with ANH (hematocrit down to 28%). ⋯ Our data suggest that ANH of moderate degree can be combined with esmolol-induced CH to improve blood conservation in surgical patients.

Randomized Controlled Trial Comparative Study Clinical TrialRemifentanil-propofol vs. sufentanil-propofol: optimal combinations in clinical anesthesia.
Two opioid regimens, computer-simulated to provide optimal general anesthesia in combination with propofol, were compared using clinical criteria. ⋯ The present clinical trial conducted in thyroid surgery is consistent with previous computer-simulated opioid-propofol combinations with respect to intraoperative and recovery variables. Effect-site propofol ranges were, however, lower than expected.
