To describe the use of dexmedetomidine for sedation in a critically ill infant undergoing magnetic resonance imaging (MRI). ⋯ Dexmedetomidine and a small dose of propofol were used successfully to sedate a critically ill infant for MRI. More studies are required to determine the role of this unique drug in the pediatric population.

Our objective was to demonstrate that preemptive vessel dilator cricothyrotomy may be useful when managing the patient with airway obstruction. ⋯ Vessel dilator cricothyrotomy as a preemptive procedure in the management of patients with significant supraglottic airway obstruction may be a useful addition to the anesthesiologists' armamentarium of airway management devices.

Epidural cannulation is a difficult technique in the patient undergoing scoliosis repair, due to axial rotation of the vertebral bodies, as well as angulation of the spinal processes. This case series was performed to investigate whether ultrasonography could facilitate epidural insertion in patients with scoliosis, by assessing the degree of vertebral body rotation. ⋯ We conclude that ultrasonography may have a potential role to facilitate insertion of epidural catheters in patients with scoliosis.

It has been reported that the actual flow from a syringe pump changes due to vertical movement of the pump in vitro, but a direct study of the in vivo effects of fluid delivery irregularities caused by vertical pump displacement has not been performed. The aim of this study was to assess the influence of positional changes of the syringe pump on the internal pressure (IP) and flow from the circuit, and to examine blood pressure changes caused by pump movement in animals with or without hemorrhagic shock. ⋯ Vertical displacement of the syringe pump alters the flow due to a change of line IP, and blood pressure can be affected by pump movement during NE infusion.
