Randomized Controlled Trial Comparative Study Clinical Trial
Additional droperidol, not butorphanol, augments epidural fentanyl analgesia following anorectal surgery.
To examine the effects of additional droperidol or butorphanol to epidural fentanyl infusion on postsurgical analgesia. ⋯ In this study population, additional droperidol, not butorphanol, improved postsurgical analgesia accompanied by less incidence of nausea/vomiting during epidural fentanyl administration.

Comparative Study
Effects of epidural anesthesia on the cardiovascular response to a rapid increase in isoflurane concentration.
To compare circulatory variables to an abrupt increase in isoflurance concentration via mask in patients who received either upper thoracic or lumbar epidural anesthesia, or neither. ⋯ Epidural anesthesia can blunt circulatory responses to a sudden increase in isoflurane concentration.

Case Reports
Cardiac arrest due to succinylcholine-induced hyperkalemia in a patient with wound botulism.
Cardiac arrest due to hyperkalemia is a known complication of succinylcholine administration in patients with neuromuscular disease, extensive burns, and prolonged immobility. We report a case of hyperkalemic cardiac arrest following the administration of succinylcholine in a patient suffering from wound botulism.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Pooled analysis of three large clinical trials to determine the optimal dose of dolasetron mesylate needed to prevent postoperative nausea and vomiting. The Dolasetron Prophylaxis Study Group.
To identify the maximally effective dolasetron dose (i.e., maximum efficacy with minimum adverse events) for prevention of postoperative nausea and vomiting (PONV) using the statistical power generated in a pooled patient sample from three large, nearly identical clinical trials. ⋯ Dolasetron 12.5 mg, given near the end of anesthesia, is the maximally effective dose studied for preventing postoperative nausea and vomiting.

Comparative Study
Comparison of acute normovolemic hemodilution and preoperative autologous blood donation in clinical practice.
To compare, by model simulation, acute normovolemic hemodilution (ANH) and preoperative autologous blood donation (PABD) to predict their efficacy in current clinical practice. To discuss their similarities and offer guidelines based on expected operative blood loss. ⋯ PABD exemplifies a "chronic" form of ANH in current clinical practice and offers little advantage over ANH as a blood conservation technique for high-blood-loss operations. When surgical blood loss is predictably mild to moderate (range 250 to 1,000 mL), neither blood conservation technique is necessary.
