Randomized Controlled Trial
Utility of gum-elastic bougie for tracheal intubation during chest compressions in a manikin: a randomized crossover trial.
The utility of the gum-elastic bougie (GEB) as an assistive device for tracheal intubation during chest compressions has not been sufficiently validated. This study aimed to compare the utility of the GEB during chest compressions on an adult manikin. ⋯ These findings suggest that the GEB facilitates tracheal intubation during chest compressions performed by novice physicians in adult simulations.

Randomized Controlled Trial
The effects of proximal and distal routes of intraosseous epinephrine administration on short-term resuscitative outcome measures in an adult swine model of ventricular fibrillation: a randomized controlled study.
It is unknown if the anatomical distance of intraosseous (i.o.) epinephrine injection from the heart affects resuscitative outcome. The purpose of this study was to explore the relationships between the anatomical distance of i.o. epinephrine injection and measures of resuscitative outcome in an adult swine model of ventricular fibrillation (VF). ⋯ The anatomical distance of i.o. epinephrine injection from the heart did not affect short-term measures of resuscitative outcome in an adult swine model of VF including the occurrence of ROSC, 30 minute post-ROSC survival, and time to ROSC. Rapidly administered epinephrine, irrespective of route of administration, increased the chance ROSC and survival to 30 minutes post-ROSC would occur in this study.

Shock Index (SI) is considered to be a predictor of mortality in many medical and trauma settings. Many studies have shown its superiority to conventional vital sign measurements in mortality prediction. ⋯ In nontrauma adult patients, triage time SI, MSI, and Age SI are superior to blood pressure for mortality prediction in ESI level 2. They can be used alone or in combination with similar results, but their low sensitivity and specificity make them usable only as an adjunct for this purpose.

Case Reports
Use of intra-aortic balloon pump support for oozing-type cardiac rupture after acute myocardial infarction.
Left ventricular free wall rupture usually leads to acute hemopericardium and sudden cardiac death resulting in cardiac tamponade. Rarely, only a few patients with subacute free wall rupture such as oozing-type ventricular rupture or left ventricular false aneurysm may permit time for pericardiocentesis and surgery. We report a 63-year-old man with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention about 12 hours from the onset, and cardiac tamponade occurred on the second day. ⋯ In the following 24 hours, about 600 mL of hemorrhagic pericardial fluid was drained. The most likely diagnosis was concerning for oozing-type ventricular rupture, and a conservative approach was decided. The patient survived to the acute phase under IABP support and was discharged with complete recovery.

The study aims to assess if electrocardiographic (ECG) abnormalities could predict the development of neurogenic pulmonary edema (NPE) within 24 hours in cases of spontaneous subarachnoid hemorrhage (SAH). ⋯ Electrocardiographic abnormalities, especially abnormal Q or QS wave and NSSTTCs, may predict the development of NPE within 24 hours in adult patients with spontaneous SAH.
