Comparative Study Clinical TrialA comparison of Plateletworks and platelet aggregometry for the assessment of aspirin-related platelet dysfunction in cardiac surgical patients.
To compare the assessment of aspirin-related platelet dysfunction using Plateletworks (Helena Laboratories, Beaumont, TX), a new point-of-care platelet function analyzer, with turbidometric platelet aggregometry, in cardiac surgical patients. ⋯ These findings suggest that Plateletworks is of limited use for the detection of aspirin-related platelet defects in cardiac surgical patients.

Randomized Controlled Trial Comparative Study Clinical TrialEffectiveness of a circulating-water warming garment in rewarming after pediatric cardiac surgery using hypothermic cardiopulmonary bypass.
To evaluate the effectiveness and safety of the ALLON 2001 microprocessor-based thermoregulation system in pediatric patients undergoing cardiac surgery requiring hypothermic cardiopulmonary bypass compared with the routine thermal care. ⋯ The investigated thermoregulation system was effective in preventing the after-drop of temperature that occurs after cardiopulmonary bypass in small infants compared with routine warming methods.

Randomized Controlled Trial Clinical TrialDecreased concentration of antithrombin after preoperative therapeutic heparin does not cause heparin resistance during cardiopulmonary bypass.
To determine if preoperative heparin therapy causes an increase in the incidence of intraoperative heparin resistance by reducing the concentration of antithrombin in plasma. ⋯ Preoperative heparin causes an increased incidence of heparin resistance and reduced antithrombin concentrations. However, heparin resistance was not causally related to reduced antithrombin because antithrombin concentrations were not different between heparin-resistant and heparin-responsive patients in the POHI group.

Clinical TrialProcalcitonin and C-reactive protein kinetics in postoperative pediatric cardiac surgical patients.
To determine the kinetics of procalcitonin (PCT) and C-reactive protein (CRP) concentration after pediatric cardiac surgery with cardiopulmonary bypass. ⋯ An increment of both PCT and CRP was observed just after CPB. However, PCT values remained within reference values, whereas CRP concentrations increased significantly after CPB until the third day. These preliminary results suggest that PCT was more effective than CRP to monitor patients with SIRS and a favorable outcome.

Anesthetic considerations during caval inflow occlusion in children with congenital heart disease.
Caval inflow occlusion (IO) was introduced to facilitate surgical pulmonary and aortic valvotomy without cardiopulmonary bypass (CPB). Although a technique that is used infrequently today, it remains useful in some patients with complex single-ventricle congenital cardiac defects who require an atrial septectomy. The potential for complications and anesthetic considerations have not been described previously. ⋯ IO is an effective technique for short intracardiac procedures without the need for CPB. Close collaboration between anesthesia and surgical staff is essential to keep the duration of IO as short as possible and because of the potential for hemodynamic instability.
