Randomized Controlled Trial Clinical TrialProinflammatory cytokine release during pediatric cardiopulmonary bypass: influence of centrifugal and roller pumps.
It has been proposed that nonocclusive centrifugal pumps may elicit less blood cell trauma and hence a reduced inflammatory response than standard roller pumps. However, there have been no reports describing the impact of such pumps on proinflammatory cytokine release in pediatric cohorts. ⋯ The current study confirms the proinflammatory nature of pediatric CPB surgery, but failed to show a significant advantage of centrifugal pumping over roller perfusion in terms of the inflammatory response.

Randomized Controlled Trial Clinical TrialForced-air warming is no more effective than conventional methods for raising postoperative core temperature after cardiac surgery.
To determine whether postoperative forced-air warming of cardiac bypass patients in the intensive care unit (ICU) results in faster rate of warming and improved outcomes compared with more conventional ICU warming methods. ⋯ There is no evidence from this study to warrant use of forced-air warming devices for the care of postoperative cardiac surgical patients in the ICU.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA randomized multicenter double-blind comparison of urapidil and ketanserin in hypertensive patients after coronary artery surgery.
To compare the hemodynamic responses, safety, and efficacy of urapidil and ketanserin in hypertensive patients after coronary artery surgery. ⋯ In contrast to ketanserin, urapidil did not increase heart rate. Urapidil was more effective in lowering arterial blood pressure than ketanserin. However, one third of the patients treated with urapidil developed hypotension after 60 minutes of continuous infusion.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the effects of sodium nitroprusside and isoflurane during rewarming on cardiopulmonary bypass.
Afterdrop in core temperatures after discontinuation of cardiopulmonary bypass (CPB) is reported to be a sign of inadequate total body rewarming on CPB. The purpose of this study was to compare the effects of three different drug regimens on hemodynamic stability and the uniformity of rewarming during the rewarming period of CPB. ⋯ Isoflurane produced more stable hemodynamic conditions than SNP during the rewarming period, improved the uniformity of rewarming, and permitted earlier extubation in the intensive care unit (ICU). It is concluded that isoflurane alone is capable of fulfilling the anesthesia needs during hypothermia and the rewarming period of CPB.
