Randomized Controlled Trial Comparative Study
The effect of two different counting methods on the quality of CPR on a manikin--a randomized controlled trial.
To compare the quality of cardiopulmonary resuscitation (CPR) and rescuers' exhaustion using different methods of counting, and to establish an appropriate method of counting. ⋯ Counting from 1 to 10 three times in Chinese as opposed to 1-30 results in better quality chest compressions. Counting from 1 to 10 three times was associated with less user feelings of fatigue, and a longer time to peak heart rate. These findings support the teaching of counting compressions 1-10 three times during CPR.

The optimal depth of sternal compressions during cardiopulmonary resuscitation (CPR) in infants is unknown; current guidelines recommend compressing to a depth of 1/3rd to 1/2 the anterior-posterior (AP) diameter of the chest. Our experience to compress the chest at 1/3rd the AP diameter often fails to provide an adequate blood pressure response. We reviewed our experience with CPR, depth of compressions, and arterial blood pressure response in a cohort of 6 infants having cardiac surgery and subsequent cardiac arrest. ⋯ The mean diastolic pressure was similar with both strategies (30.5 vs. 30.6mm Hg, p=0.99). In this cohort of 6 infants having cardiac surgery and subsequent cardiac arrest, attempting to compress the chest at 1/2 the AP diameter increased systolic blood pressure by 62% compared to attempting to compress 1/3rd the AP diameter. Perhaps resuscitators should attempt to compress infants' chests 1/2 rather than 1/3rd the AP diameter of the chest.

With the recent introduction of therapeutic hypothermia the application of sedation becomes necessary in cardiac arrest patients. We therefore analysed the usefulness of the Glasgow coma score (GCS) for outcome prediction in survivors of cardiac arrest treated with therapeutic hypothermia. ⋯ Our results indicate that monitoring of the GCS is a simple and reliable method for clinical outcome assessment in patients treated with therapeutic hypothermia. Thus, GCS monitoring remains a powerful tool to predict outcome of patients treated with therapeutic hypothermia.

Widespread application of early goal-directed therapy (EGDT) and the severe sepsis resuscitation bundle is limited by clinician knowledge, skills and experience. This study evaluated use of simulation-based teaching during medical training to increase future clinician knowledge in the above therapies for severe sepsis and septic shock. ⋯ Medical simulation is an effective method of educating EGDT and the severe sepsis resuscitation bundle to medical students with limited experience in patient care. The results suggest that our course may be of further benefit at increasing clinical experience with this intensive protocol for the management of severe sepsis and septic shock.

We developed a suction laryngoscope, which enables simultaneous suction and laryngoscopy in cases of airway haemorrhage and evaluated its potential benefits in physicians with varying emergency medical service experience. ⋯ In a model of severe simulated airway haemorrhage, employing a suction laryngoscope significantly decreased the likelihood of oesophageal intubations in physicians with occasional emergency medical service experience.
