The temperature and humidity of inspired gases in infants using a pediatric circle system: effects of high and low-flow anesthesia.
The effects of low-flow anesthesia on the temperature and humidity of the inspired gas in infants during mechanical ventilation is unknown. This study was designed to evaluate the temperature and humidity of the inspired gas in infants using a pediatric circle absorber system with high and low fresh gas flow (HFGF and LFGF) anesthesia. ⋯ Low-flow anesthesia with a pediatric circle system in infants neither increases the temperature of the inspired gas, nor achieves the minimum humidity of 50% reported to prevent ciliary damage, although the humidity during LFGF did increase threefold compared with HFGF. To maintain the temperature and humidity of the inspired gas during mechanical ventilation in infants, passive or active gas humidification should be used.

Case ReportsAwake nasotracheal intubation using fiberoptic bronchoscope in a pediatric patient with Freeman-Sheldon syndrome.
The Freeman-Sheldon syndrome is a congenital disease primarily affecting the facial, limb and respiratory muscles that give rise to classical clinical features including typical whistling face and short webbed neck associated with difficult intubation. We present successful awake nasotracheal intubation in a 6-year-old patient with typical clinical features of Freeman-Sheldon syndrome by using fiberoptic bronchoscope on two separate occasions.

Case ReportsPost dural puncture headache in a pediatric patient with idiopathic intracranial hypertension.
We describe the occurrence of postdural puncture headache (PPDH) in an adolescent with idiopathic intracranial hypertension (IIH) and its successful management with an epidural blood patch. PPDH is a very rare occurrence in patients with intracranial hypertension and is described as a paradoxical situation in the literature. There are only two previous case reports (in adults) of the possible association. ⋯ After a failed trial of conservative management, she had an uneventful but curative epidural blood patch with 15 ml of autologous venous blood and was able to return to school the day after the blood patch. Follow-up review by her neuro-ophthalmologist shows resolution of her headaches, considerable improvement in her visual field defect and resolution of papilledema. This is the first report of PPDH and its successful management with an epidural blood patch in a pediatric patient with IIH.

Pharmacokinetics and efficacy of ropivacaine for continuous epidural infusion in neonates and infants.
The primary objective of this noncomparative study was to evaluate the pharmacokinetics of ropivacaine during a 48-72-h continuous epidural infusion of ropivacaine in children under 1 year. The secondary objectives were to assess efficacy and safety. ⋯ Epidural infusions (0.2-0.4 mg.kg(-1).h(-1) ropivacaine) provided satisfactory pain relief in neonates and infants under 1 year. As plasma concentrations of unbound ropivacaine were not influenced by the duration of the infusion, ropivacaine can be safely used for postoperative epidural infusion for 48-72 h. Levels of unbound ropivacaine were higher in the neonates than in the infants, but were below threshold concentrations for CNS toxicity in adults (> or =0.35 mg.l(-1)). This should not preclude the use of ropivacaine infusions in neonates but suggests a need for caution during the first weeks of life.
