Randomized Controlled Trial Comparative Study
A randomised trial comparing a 4-stage to 2-stage teaching technique for laryngeal mask insertion.
To compare the '4-stage' teaching technique (demonstration, deconstruction, formulation, performance) with the traditional '2-stage' teaching technique (deconstruction, performance) in laryngeal mask airway (LMA) insertion. ⋯ The 2-stage teaching technique is not statistically different to the 4-stage teaching method in efficacy of LMA insertion skill acquisition or retention.

In trauma patients with chest injuries, traumatic pericardial effusion is an important scenario to consider because of its close linkage to cardiac injury. Even with advances in imaging, diagnosis remains a challenge and use of which surgical approach is controversial. This study reviews the treatment algorithm, surgical outcomes, and predictors of mortality for traumatic pericardial effusion. ⋯ Precise diagnoses of traumatic pericardial effusions are still challenging and easily omitted even with FAST, repeat cardiac echo and CT. The number of patients with traumatic pericardial effusion requiring surgical repair is high. Standardized therapeutic protocol, different surgical approaches have not impact on survival. Correct identification, prompt drainage, and preparedness for concomitant cardiac repair seem to be the key to better outcomes.

Therapeutic hypothermia has been shown to provide neuroprotection and improved survival in patients suffering a cardiac arrest. We report outcomes of consecutive patients receiving therapeutic hypothermia for cardiac arrest and describe predictors of short and long-term survival. ⋯ Therapeutic hypothermia is useful in the treatment of patients suffering a cardiac arrest. Several clinical factors may aid in predicting patients who are likely to survive after a cardiac arrest.

Mild to moderate therapeutic hypothermia (TH) has been shown to improve survival and neurological outcome in patients resuscitated from out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF) as the presenting rhythm. This approach entails the management of physiological variables which fall outside the realm of conventional critical cardiac care. Management of serum potassium fluxes remains pivotal in the avoidance of lethal ventricular arrhythmia. ⋯ Therapeutic hypothermia is associated with a significant decline in serum potassium during cooling. Hypothermic core temperatures do not appear to protect against ventricular arrhythmia in the context of severe hypokalemia and cautious supplementation to maintain potassium at 3.0 mmol l(-1) appears to be both safe and effective.
