Randomized Controlled Trial Comparative StudyComparison of rescue techniques for failed chloral hydrate sedation for magnetic resonance imaging scans-additional chloral hydrate vs intranasal dexmedetomidine.
Chloral hydrate, a commonly used sedative in children during noninvasive diagnostic procedures, is associated with side effects like prolonged sedation, paradoxical excitement, delirium, and unpleasant taste. Dexmedetomidine, a highly selective α-2 agonist, has better pharmacokinetic properties than chloral hydrate. We conducted this prospective, double-blind, randomized controlled trial to evaluate efficacy of intranasal dexmedetomidine with that of a second oral dose of chloral hydrate for rescue sedation during magnetic resonance imaging (MRI) studies in infants. ⋯ Intranasal dexmedetomidine induced satisfactory rescue sedation in 1- to 6-month-old infants during MRI study, and appears to cause sedation in a dose-dependent manner.

Postoperative pain control with paravertebral catheters after pediatric total pancreatectomy and islet autotransplantation: a retrospective cohort study.
Total pancreatectomy and islet autotransplantation (TPIAT) has been used to treat pediatric patients with chronic pancreatitis. The primary symptom of this disease is extreme poorly controlled pain. This results in significant alterations in the quality of life of the patient. We sought to determine if the addition of bilateral thoracic paravertebral catheters with continuous ropivacaine infusion would improve postoperative opioid use and pain control. ⋯ Bilateral paravertebral catheters may provide decreased opioid use and improved postoperative pain control after TPIAT.

Usefulness of stroke volume variation to assess blood volume during blood removal for autologous blood transfusion in pediatric patients.
Dynamic variables based on the heart-lung interaction induced by positive pressure ventilation have not been shown to be useful in assessing cardiac preload in pediatric patients. ⋯ Stroke volume variation obtained from the FloTrac/Vigileo(TM) monitoring system revealed a strong correlation with EBV during ANH without surgical stimulation. The usefulness of this device as an indicator of cardiac preload under hypovolemic or normovolemic conditions in children during surgery remains to be determined.

Observational StudyValidity of sidestream endtidal carbon dioxide measurement in critically ill, mechanically ventilated children.
Capnography is used to monitor the endtidal carbon dioxide tension (EtCO2) in exhaled gas. Sidestream capnography has great potential to monitor mechanically ventilated pediatric patients, given the continuous sampling from the endotracheal tube into a gas sensor. However, hemodynamic and respiratory impairments may reduce reliability and validity of sidestream capnography to monitor arterial carbon dioxide tension (PaCO2) in critically ill, mechanically ventilated children. ⋯ Sidestream capnography in mechanically ventilated infants and children seems moderately reliable and valid when corrected for individual differences. Therefore, it could only be used with caution for trend estimation in the individual patient.
