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
A comparison of defibrillation efficacy between different impedance compensation techniques in high impedance porcine model.
Impedance compensation methods differ markedly among manufacturers and can play an important role in defibrillation success. In this study we compared the efficacy of two different commercial defibrillators based on defibrillation success in a high impedance porcine model of cardiac arrest. The first defibrillator (A) compensates high impedance by controlling current with fixed shock duration, while the second defibrillator (B) by prolonging the shock duration. ⋯ For transthoracic impedances greater than average, the current-based compensation technique was more effective than the duration-based compensation technique.
