Randomized Controlled Trial Clinical TrialUse of low-dose rocuronium for intubation of children during volunteer surgery abroad.
Low-dose rocuronium (ROC) might improve safety during volunteer surgery abroad (VSA) by facilitating intubation with a lower halothane concentration than is typically used. We hypothesized that 0.25 mg.kg(-1) of ROC would improve intubation conditions during 3% halothane induction and still allow for rapid return to spontaneous ventilation (SV). ⋯ When administering 3% halothane for induction of VSA patients, a high frequency of adequate intubation conditions can be achieved without a relaxant, rendering the known benefits of 0.25 mg.kg(-1) of ROC unapparent. ROC 0.25 mg.kg(-1) does allow rapid return to SV.

Randomized Controlled Trial Comparative Study Clinical TrialEvaluation of relatively low dose of oral transmucosal ketamine premedication in children: a comparison with oral midazolam.
Oral Transmucosal ketamine (lollipop) has been shown to be an effective, harmless preoperative medication for children. However, its efficacy was not compared with commonly used premedication drugs. We, therefore, compared the efficacy of oral transmucosal ketamine with oral midazolam for premedication in children. ⋯ These results indicate that a relatively low dose of oral transmucosal ketamine premedication provides no benefits over oral midazolam in children.

Randomized Controlled Trial Comparative Study Clinical TrialRandomized trial comparing overnight preoperative fasting period Vs oral administration of apple juice at 06:00-06:30 am in pediatric orthopedic surgical patients.
We aimed to evaluate the efficacy of clear liquids orally administered at 06:00-06:30 am on the morning of surgery to reduce prolonged preoperative fasting periods. ⋯ A 15 ml.kg(-1) of apple juice for patients of <3 years of age or 10 ml.kg(-1) for older children, at 06:00-06:30 am of the surgical morning is a simple procedure to prevent dehydration and to produce positive behavior in low-risk, pediatric surgical patients.

Pilot study of neuraxial imaging by ultrasound in infants and children.
Ultrasonography is becoming an important adjunct in regional anesthesia. Epidural anesthesia may pose significant challenges in infants and children because of difficulties in identifying the epidural space. In addition, epidural catheters are sometimes difficult to advance. The present study was performed to evaluate an optimal ultrasound technique for direct visualization of neuraxial structures in children. ⋯ Paramedian longitudinal scans with linear probes are the most favorable method of imaging neuraxial anatomy at lumbar and thoracic cord levels in infants and children, with the best results in neonates up to 3 months of age. Based on these results, and using real time imaging, a practical technique for ultrasound-guided epidural anesthesia for neonates and infants at lumbar and thoracic levels of the spinal cord is planned.

Comparative StudyCatheterization of the radial or brachial artery in neonates and infants.
In neonates and small children, percutaneous insertion of arterial catheters may be very difficult because of the small diameter of the arteries. Multiple attempts at cannulation are common and may be a predictor of serious adverse events following arterial cannulation. As an end artery, the brachial artery is usually not recommended for cannulation. However, limited data exist about brachial artery catheterization in neonates and young children. In this retrospective study, we report our experience with arterial indwelling catheters placed in neonates and small children prior to surgery for congenital heart defects. ⋯ Even considering the nature of a retrospective study design, we conclude that the brachial artery could be considered for cannulation in neonates and small children.
