Randomized Controlled TrialPropofol and propofol-ketamine in pediatric patients undergoing cardiac catheterization.
We investigated the effects of propofol and propofol-ketamine on hemodynamics, sedation level, and recovery period in pediatric patients undergoing cardiac catheterization. We performed a prospective, randomized, double-blind study. The study included 60 American Society of Anesthesiologists physical status II or III (age range, 1 month-13 years) undergoing cardiac catheterization for evaluation of congenital heart disease. ⋯ Ten patients in group 1 and 3 patients in group 2 required additional fentanyl doses (p = 0.057). The number of additional propofol doses was lower in group 2 (p < 0.05). Propofol combined with low-dose ketamine preserves mean arterial pressure better without affecting the recovery and thus is a good option in pediatric patients undergoing cardiac catheterization.

Multicenter Study Controlled Clinical TrialAdministration of steroids in pediatric cardiac surgery: impact on clinical outcome and systemic inflammatory response.
Cardiopulmonary bypass (CPB) is associated with a systemic inflammatory response. Pre-bypass steroid administration may modulate the inflammatory response, resulting in improved postoperative recovery. We performed a prospective study in the departments of cardiovascular surgery and pediatric intensive care medicine of two university hospitals that included 50 infants who underwent heart surgery. ⋯ Postoperative plasma levels of interleukin-8 were correlated with the duration of CPB time (r = 0.62, p < 0.001). Administration of steroids had no significant impact on the laboratory parameters of inflammation. Administration of prednisolone into the priming solution of the CPB circuit had no measurable influence on postoperative recovery and did not suppress the inflammatory response.

Case ReportsStent implantation for recurrent interatrial obstruction in an infant with hypoplastic left heart syndrome.
We report the case of a 19-month-old girl with hypoplastic left heart syndrome who, after Norwood stage 1 and 2 procedures, developed recurrent interatrial obstruction and was treated effectively with stent implantation. The stent was explanted electively 14 months after implantation and showed almost no endothelium formation. Therefore, there was no need for redo atrioseptectomy and the surgical intervention could be staged electively.

Case ReportsUnilateral pulmonary edema: unusual presentation of acute rheumatic fever.
Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical condition and not readily recognized early and managed accordingly. Acute rheumatic fever, which is a common disease in developing countries, does not commonly present with UPE. ⋯ We conclude that UPE should be considered in the differential diagnosis for the patient with clinical criteria of rheumatic fever who presents with unilateral lung opacification. With early recognition and antifailure treatment, it is possible to reduce morbidity and mortality in such patients.

Milrinone and low cardiac output following cardiac surgery in infants: is there a direct myocardial effect?
We assessed the effect of milrinone on myocardial function in pediatric patients with postoperative low cardiac output syndrome by index of myocardial performance in a prospective, open-label, nonrandomized, consecutive study. Fifteen patients with low cardiac output syndrome following cardiac surgical treatment were studied in the tertiary cardiothoracic pediatric intensive care unit between April 2001 and November 2003 (age range, 0.2-16 months; median, 7; weight, 2.7-11.8 kg; median, 5). ⋯ Treatment with milrinone led to improvement in biventricular myocardial function [mean right ventricular index from 0.521 (SD-0.213) to 0.385 (SD-0.215), p = 0.003; mean left ventricular index from 0.636 (SD-0.209) to 0.5 (SD-0.171), p = 0.012). No difference was found in the values of heart rate corrected right or left ventricular ejection time prior to and while on treatment with milrinone (right ventricle: mean, 1.23 (SD-0.42) and 1.14 (SD-0.48), p = 0.29; left ventricles: mean, 1.17 (SD-0.51) and 1.13 (SD-0.48), p = 0.66) Our data support the direct myocardial effect of milrinone as part of the mechanism behind its already proven benefit in children with low cardiac output syndrome following cardiac surgery.
