Changes of dorsalis pedis artery flow pattern after caudal block in children: observational study using a duplex sonography.
To evaluate the changes of the flow velocity, the volume flow, and the diameter of dorsalis pedis artery using a duplex ultrasonography after caudal block with sevoflurane anesthesia in children. ⋯ Duplex sonographic measurements indicate that a caudal block changes the flow patterns of the dorsalis pedis artery significantly in the anesthetized children.

Comparative StudyComparison of effective inspired concentration of sevoflurane in preterm infants with different postconceptual ages.
Screening examination for retinopathy of prematurity (ROP) is stressful and painful to the neonate. Sevoflurane has been used successfully in anesthesia for full-term and premature neonates and has been recently used for pediatric outpatient procedures. In this study, we examined the effective inspired concentration of sevoflurane to prevent movement in response to stimulation of examination in 50% of patients (EIC50) of sevoflurane, as well as the response of sevoflurane to age in the preterm outpatients undergoing fundus examination. ⋯ Anesthesia with inhaled sevoflurane by a face mask can be accomplished in preterm outpatients undergoing fundus examination without intubation and i.v. accession. The EIC50 is lower, and the induction time is shorter in smaller aged patients compared with those in older ones.

Emergency cricothyrotomy in infants--evaluation of a novel device in an animal model.
According to different algorithms of airway management, emergency cricothyrotomy is the final step in managing an otherwise not accessible airway. As an alternative to an open surgical procedure, minimally invasive approaches exist. Quicktrach baby™ is a commercially available set for a minimal invasive cricothyrotomy in infants. The set consists of a plastic cannula over a metal needle for direct placement in the trachea. So far, this device has not been evaluated for its intended use. ⋯ Quicktrach™ baby proved to be a reliable technique. In the animal model, it is easy and fast to perform. Only a few minor complications occurred. Sufficient ventilation was possible in all attempts.
