Comparative Study
Quantitative analysis of chest compression interruptions during in-hospital resuscitation of older children and adolescents.
To quantitatively describe pauses in chest compression (CC) delivery during resuscitation from in-hospital pediatric and adolescent cardiac arrest. We hypothesized that CPR error will be more likely after a chest compression provider change compared to other causes for pauses. ⋯ Provider switches account for a significant portion of no-flow time. Measurable residual leaning is more likely after provider switch. Feedback systems may allow some providers to continue high quality CPR past the recommended switch time of 2 min during in-hospital resuscitation attempts.

Randomized Controlled Trial Comparative Study
"Mouth to mouth ventilation": a comparison of the laryngeal mask airway with the Laerdal Pocket Facemask.
Ten nurses with basic airway management experience were formally trained to use a classic laryngeal mask airway (LMA) and a Laerdal Pocket Facemask (LPFM) for oxygen enriched expired air ventilation (EEAV). They then used both of these devices for EEAV in a randomised fashion in 100 anaesthetised ASA I/II patients for elective surgery. EEAV was considered successful if the patient's arterial oxygen saturation was maintained above 93% on room air for 3 min. ⋯ There was no apparent learning curve for either apparatus. Mean time in seconds (s) for first successful ventilation from picking up the apparatus was 26.8s and 15.1s, for the LMA and LPFM respectively (P<0.005). Although the LMA took significantly longer time to insert, it proved to be more successful and easier to use than the LPFM for EEAV.

Comparative Study
Extubation force: a comparison of adhesive tape, non-adhesive tape and a commercial endotracheal tube holder.
This study compares adhesive tape, non-adhesive tape and a commercial endotracheal tube holder in terms of the force required to extubate endotracheal tubes from a cadaver. ⋯ Although the Lillehei method provided the greatest resistance to tube dislodgement, it may not be ideal for the prehospital or emergency department context. The Thomas Tube Holder was quick and effective and may provide a good compromise in these environments, although once time is no longer important, clinicians may elect to revert to the Lillehei method which provides greater security.

Comparative Study
Effects of large volume, ice-cold intravenous fluid infusion on respiratory function in cardiac arrest survivors.
International guidelines for cardiopulmonary resuscitation recommend mild hypothermia (32-34 degrees C) for 12-24h in comatose survivors of cardiac arrest. To induce therapeutic hypothermia a variety of external and intravascular cooling devices are available. A cheap and effective method for inducing hypothermia is the infusion of large volume, ice-cold intravenous fluid. ⋯ Resuscitation from cardiac arrest is associated with a deterioration in respiratory function. The infusion of large volumes of cold fluid does not cause a statistically significant further deterioration in respiratory function. A larger, randomized and prospective study is required to assess the efficacy and safety of ice-cold fluid infusion for the induction of therapeutic hypothermia.
