Randomized Controlled Trial Comparative Study Clinical TrialA comparison of amrinone with sodium nitroprusside for control of hemodynamics during infrarenal abdominal aortic surgery.
The control of hemodynamic changes during surgical resection of abdominal aortic aneurysms (AAA) remains a challenge to anesthesiologists. In the past, hypertensive episodes have been treated with sodium nitroprusside (SNP). However, amrinone may provide some benefits when compared with SNP because of its positive inotropic and vasodilatory properties. Therefore, the purpose of this study was to compare amrinone with SNP for hemodynamic control during AAA surgery. ⋯ This study demonstrates that amrinone provides equivalent hemodynamic control to SNP during abdominal aortic aneurysm surgery because it allows moderate reductions in blood pressure without affecting other hemodynamic measurements. Further studies are needed to assess whether patients with poor preoperative left ventricular function would benefit from amrinone management during AAA resection.

Randomized Controlled Trial Comparative Study Clinical TrialPain outcomes after thoracotomy: lumbar epidural hydromorphone versus intrapleural bupivacaine.
To evaluate postthoractomy analgesia in patients receiving lumbar epidural hydromorphone versus intrapleural bupivacaine. ⋯ Epidural hydromorphone is superior to intrapleural bupivacaine in achieving satisfactory pain outcomes during the first 5 hours after thoracotomy.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of intrapleural versus intravenous morphine for postthoracotomy pain management.
To compare the analgesic effects of intrapleural and intravenous morphine administration for postthoracotomy pain management. ⋯ IPM achieved better analgesia than IVM and this effect is probably attributable to peripheral effects of morphine.
