Randomized Controlled Trial Multicenter StudyRed blood cell transfusion thresholds in pediatric patients with sepsis.
In children with severe sepsis or septic shock, the optimal red blood cell transfusion threshold is unknown. We analyzed the subgroup of patients with sepsis and transfusion requirements in a pediatric intensive care unit study to determine the impact of a restrictive vs. liberal transfusion strategy on clinical outcome. ⋯ In this subgroup analysis of children with stable sepsis, we found no evidence that a restrictive red cell transfusion strategy, as compared to a liberal one, increased the rate of new or progressive multiple organ dysfunction syndromes. Furthermore, a restrictive transfusion threshold significantly reduced exposure to blood products. Our data suggest that a hemoglobin level of 7.0 g/dL may be safe stabilized for children with sepsis, but further studies are required to support this recommendation.

Randomized Controlled TrialAngiotensin-converting enzyme inhibition alters the inflammatory and fibrinolytic response to cardiopulmonary bypass in children.
Many children with a congenital heart defect undergo surgical correction requiring cardiopulmonary bypass. One-sixth of these patients take an angiotensin-converting enzyme inhibitor for heart failure treatment. The effect of angiotensin-converting enzyme inhibition on the fibrinolytic and inflammatory response in children undergoing cardiopulmonary bypass is unknown. In adults, angiotensin-converting enzyme inhibition attenuates the increase in plasminogen activator inhibitor-1 after cardiopulmonary bypass, whereas the effect on the interleukin-6 response is uncertain. This study tests the hypothesis that preoperative angiotensin-converting enzyme inhibition attenuates postoperative plasminogen activator inhibitor-1 and interleukin-6 expression after cardiopulmonary bypass in children. ⋯ Angiotensin-converting enzyme inhibition attenuates the increase in postoperative plasminogen activator inhibitor-1 but enhances the interleukin-6 response in children undergoing cardiopulmonary bypass.

Randomized Controlled TrialA trial of methadone tapering schedules in pediatric intensive care unit patients exposed to prolonged sedative infusions.
To compare the efficacy of a low-dose methadone tapering schedule to a high-dose methadone tapering schedule in pediatric intensive care unit patients exposed to infusions of fentanyl, with or without infusions of midazolam, for ≥ 5 days. ⋯ Patients who received infusions of fentanyl for at least 5 days were just as likely to complete a low-dose methadone taper as a high-dose methadone taper. Because of the risks of both withdrawal and oversedation with any fixed methadone schedule, the methadone dose must be adjusted according to each patient's response.
