To evaluate the hemodynamic response in the prone position in surgical patients by measuring the effects of prone positioning on cardiac function using transesophageal echocardiography (TEE). ⋯ The prone position caused LVV to decrease. The prone position also led to decreased systolic PVFV and PVVTI and enhancement of diastolic PVFV and PVVTI. These changes were probably due to a decrease in the venous return due to inferior vena caval compression, and decreased left ventricular compliance due to increased intrathoracic pressure in the prone position.

Randomized Controlled Trial Multicenter Study Clinical Trial
A double-blind, parallel-group, placebo-controlled, dose-ranging, multicenter study of intravenous granisetron in the treatment of postoperative nausea and vomiting in patients undergoing surgery with general anesthesia.
To compare the effectiveness of granisetron with placebo in the treatment of established postoperative nausea and vomiting (PONV). ⋯ Granisetron was significantly more effective than placebo in all groups. Further studies in specific subgroups may be warranted.

Randomized Controlled Trial Clinical Trial
Combined popliteal and posterior cutaneous nerve of the thigh blocks for short saphenous vein stripping in outpatients: an alternative to spinal anesthesia.
To compare a combination of peripheral nerve blocks with spinal anesthesia in ambulatory patients undergoing short saphenous vein stripping. ⋯ The combination of popliteal and posterior cutaneous nerve of the thigh blocks provided adequate anesthesia and a faster recovery profile with a similar subjective acceptance of both anesthetic techniques in ambulatory patients undergoing short saphenous vein stripping in the prone position.

Randomized Controlled Trial Clinical Trial
Spontaneous movements associated with rocuronium injection: the effects of prior administration of fentanyl.
To determine if prior injection of fentanyl decreases the incidence of spontaneous movements during rocuronium administration. ⋯ Prior injection of fentanyl significantly decreases the incidence of spontaneous movements associated with rocuronium administration.

Randomized Controlled Trial Comparative Study Clinical Trial
Epidural block for obstetrics: comparison of bolus injection of local anesthetic with gravity flow technique.
To test the hypothesis that slow administration of local anesthetic into the epidural space by gravity flow reduces the incidence of signs and symptoms of unintended injection. ⋯ Gravity flow administration of local anesthetic-opioid solution during epidural block for obstetrics was associated with fewer signs of systemic drug absorption and cardiovascular perturbations than was the traditional bolus injection. This study supports the current opinion that slow administration of local anesthetic during epidural block contributes to fewer adverse events.
