Perioperative cardiac arrest and its mortality in children. A 9-year survey in a Brazilian tertiary teaching hospital.
The incidence of perioperative cardiac arrest and mortality in children is higher than in adults. This survey evaluated the incidence, causes, and outcome of perioperative cardiac arrests in a pediatric surgical population in a tertiary teaching hospital between 1996 and 2004. ⋯ Perioperative cardiac arrests were relatively higher in neonates and infants than in older children with severe underlying disease and during emergency surgery. The fact that all anesthesia attributable cardiac arrests were related to airway management and medication administration is important in prevention strategies.

Review Case ReportsAnesthesia and Prader-Willi syndrome: preliminary experience with regional anesthesia.
The constellation of neonatal hypotonia, developmental delay, hypogonadism and obesity caused by hyperphagia was first reported in 1956 and subsequently termed Prader-Willi syndrome (PWS). Genetic analysis has demonstrated abnormalities of chromosome 15. ⋯ A lumbar plexus catheter was used to provide postoperative analgesia in one patient while regional anesthesia (fasica iliaca block, spinal anesthesia, and lateral vertical infraclavicular block) was used to provide primary intraoperative anesthesia in three other patients while avoiding the need for general anesthesia. Previous reports of the anesthesia care of patients with PWS are reviewed and the potential perioperative implications of the sequelae of PWS are discussed.

Randomized Controlled TrialPharmacokinetic-pharmacodynamic relationship of rocuronium under stable nitrous oxide-fentanyl or nitrous oxide-sevoflurane anesthesia in children.
The aim of this study was to compare pharmacokinetics and pharmacokinetic-pharmacodynamic (PK-PD) relationship of rocuronium in children anesthetized with nitrous oxide (N2O) and fentanyl or with N2O and sevoflurane. ⋯ Disposition of rocuronium was similar under stable N2O-fentanyl and N2O-sevoflurane anesthesia. Sevoflurane reduced rocuronium requirements as well as decreased EC50 relevant to inhibition of T1 and rocuronium transfer to effect compartment. Therefore, the potentiating effect of sevoflurane seems to be mainly of PD origin, probably due to an increased sensitivity of the neuromuscular junction.

Randomized Controlled TrialDexmedetomidine decreases emergence agitation in pediatric patients after sevoflurane anesthesia without surgery.
The purpose of the present study was to determine whether prophylactic use of 1 microg x kg(-1) dexmedetomidine affected the incidence of emergence agitation (EA) after sevoflurane based anesthesia without surgery in children. ⋯ We concluded that a 1 microg x kg(-1) dose of i.v. dexmedetomidine reduces EA after sevoflurane anesthesia in children undergoing MRI.
