Estimation of the parameters of cardiac function and of blood volume by arterial thermodilution in an infant animal model.
Experimental studies in adults and in animals have reported that estimation of the intracardiac volumes by arterial thermodilution is a more reliable method of blood volume estimation than pressure measurement. The objective of this study has been to analyze the values of cardiac function and blood volume in an infant animal model using the arterial thermodilution technique. ⋯ Intrathoracic and intracardiac volume values obtained by arterial thermodilution are lower than those considered normal in the adult, whereas the extravascular lung water is higher. These values must be taken into account when the PiCCO method is used in small children.

Randomized Controlled Trial Comparative StudyOral sedation with midazolam and diphenhydramine compared with midazolam alone in children undergoing magnetic resonance imaging.
The purpose of this study was to compare the safety and efficacy of oral midazolam and midazolam-diphenhydramine combination to sedate children undergoing magnetic resonance imaging (MRI). ⋯ Our study indicates that the combination of oral diphenhydramine with oral midazolam resulted in safe and effective sedation for children undergoing MRI. The use of this combination might be more advantageous compared with midazolam alone, resulting in less sedation failure during MRI.

Comparative StudyConvection heating in pediatric general surgery - a comparison of warming alternatives in a mannequin study.
Numerous methods of patient warming are used to prevent intraoperative hypothermia in children. Commercially available forced air warming blankets are effective, but are single-use items. We tested a custom-designed heat dissipation unit (HDU) against one such commercially available blanket. ⋯ The custom-built HDU compares favorably in our mannequin study with a Bair Hugger forced air warming blanket. As it is reusable, it offers considerable potential savings.

Case ReportsEpidural analgesia in the surgery of congenital tracheal stenosis: slide tracheoplasty on cardiopulmonary bypass.
Epidural analgesia in children is highly effective and safe; however, it has not enjoyed great popularity in surgery that requires cardiopulmonary bypass. A major concern is the possibility of damage to blood vessels with the epidural needle or catheter and epidural hematoma formation. ⋯ Improved pulmonary function, suppressed hormonal and metabolic stress responses, easy early tracheal extubation, and good analgesia and sedation that allows neurological examination to alert any possibles hidden complications, are the advantages. A dedicated medical team is essential in the perioperative management to achieve maximum benefit for these patients.

Case ReportsAcute pancreatitis after anesthesia with propofol in a child with glycogen storage disease type IA.
Glycogen storage disorder type 1A (GSD 1A) is an inherited disorder of glycogen metabolism characterized by fasting hypoglycemia, lactic acidosis, hyperuricemia, and hyperlipidemia. These children have a higher risk of developing pancreatitis because of hypertriglyceridemia. Drug-induced pancreatitis accounts for a small proportion of cases of pancreatitis. ⋯ We present a 4-year-old girl with GSD 1A, who required tonsillectomy and adenoidectomy under general anesthesia. She developed acute pancreatitis in the postoperative period. Propofol was used as a general anesthetic and the postoperative incidence of pancreatitis is discussed.
