End-tidal carbon dioxide monitoring during sedation with a combination of midazolam and ketamine for children undergoing painful, invasive procedures.
Previous studies evaluating the respiratory effects of sedation regimens have focused on events such as a decline in O2 saturation or apnea. The current study used both end-tidal carbon dioxide (ETCO2) monitoring and pulse oximetry to evaluate the respiratory effects of midazolam and ketamine. ⋯ The incidence of adverse cardiorespiratory events associated with the current sedation regimen of midazolam-ketamine is lower than that reported with other commonly used regimens. The addition of ETCO2 monitoring provides an additional monitor to allow for early detection of airway obstruction or subclinical degrees of respiratory depression.

Apparent life-threatening events presenting to a pediatric emergency department.
To review the etiology, clinical decision-making process, and outcomes of apparent life-threatening events (ALTEs) presenting to a children's hospital emergency department (ED). ⋯ This is a diverse group of infants, many of whom appear normal following the ALTE. There are many possible diagnoses, but diagnosis correlates poorly with presenting symptoms. It also appears that many commonly performed investigations conducted in this group of infants may not be those that are most helpful for diagnosis, and doctors may be making diagnoses with little supportive evidence. Until research on this group of "first-presentation" infants provides management guidelines for family and emergency doctors, it may be prudent to advise that all such infants presenting with an ALTE should be admitted for a period of observation and further investigation. This would help ensure more accurate diagnosis, as well as provide reassurance for the family.

Needle cricothyroidotomy may provide a life-saving airway when tracheal intubation is not possible. Indications for needle cricothyroidotomy are discussed. Methods of needle/angiocatheter insertion and proposed means to connect to an oxygen source for intermittent insufflation are reviewed. ⋯ Potential complications are discussed. Complete upper airway obstruction is a contraindication to needle cricothyroidotomy because of the risks of barotrauma. In a crisis situation, the emergency practitioner needs a simple, reliable, effective, and preplanned technique to deal with the "nightmare airway."
