Efficacy and Safety of Dexmedetomidine for Prolonged Sedation in the PICU: A Prospective Multicenter Study (PROSDEX).

Objectives: We sought to evaluate dexmedetomidine efficacy in assuring comfort and sparing conventional drugs when used for prolonged sedation (≥24 hr) in critically ill patients, by using validated clinical scores while systematically collecting drug dosages. We also evaluated the safety profile of dexmedetomidine and the risk factors associated with adverse events.

Design: Observational prospective study.

Fetal surgery and maternal cortisol response to stress. The myelomeningocele sheep model.

Background: Prenatal surgery represents a multifactorial stressor event for mother and fetus. The stress response to fetal surgery was evaluated by measuring maternal plasma and amniotic fluid (AF) cortisol levels in the myelomeningocele (MMC) sheep model.

Subjects And Methods: Pregnant ewes (n = 8) underwent general anesthesia for MMC-induction (step 1: 75 d gestation), surgical defect repair (step 2: 110 d gestation), and delivery (step 3: 140 d gestation).

Prenatal detection of the cystic form of meconium peritonitis: no issues for delayed postnatal surgery.

Prenatal ultrasound (US) diagnosis and postnatal outcome are reviewed in three babies with the complex form of meconium peritonitis (MP), the cystic type. Perinatal management is discussed. Large intra-abdominal cysts with signs of calcifications were detected during the second mid-trimester.
