To describe the echocardiographic parameters of the right ventricle (RV) in first 24h post-cardiac arrest (CA) in humans; to determine if the etiology of arrest predicts RV dysfunction; to quantify parameters of the right ventricle in the first 24h post-CA. ⋯ RV dysfunction is present in the majority of post-CA patient regardless of the etiology of arrest. Further studies are needed to investigate if there are relationships between echocardiographic findings and survival and to assess temporal findings of RV function post-CA.

Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. ⋯ Manure related hydrogen sulphide intoxication is associated with a high mortality, although in some cases, recovery appears to be far more favourable than the initial presentation would suggest. Possibly protection from hypoxic injury due to induction of a suspended animation-like state by hydrogen sulphide may be responsible.

Observational Study
The influences of adrenaline dosing frequency and dosage on outcomes of adult in-hospital cardiac arrest: A retrospective cohort study.
To investigate the influence of dosing frequency and dosage of adrenaline on outcomes of cardiopulmonary resuscitation (CPR). ⋯ Higher adrenaline average dosing frequency may be associated with worse outcomes after CPR. Besides, according to current recommendations, patients with BW above 82.5kg may not receive adequate dose of adrenaline.

Observational Study
Low cerebral activity and cerebral oxygenation during immediate transition in term neonates-A prospective observational study.
To analyze whether in term neonates during immediate transition after birth low cerebral activity measured by amplitude-integrated EEG (aEEG) is linked to cerebral regional oxygen saturation (crSO2) measured by near-infrared spectroscopy (NIRS). Additionally, the cerebral fractional tissue oxygen extraction (cFTOE) was calculated to analyze whether cerebral activity is linked to cFTOE. ⋯ The present study demonstrates that neonates with initially low cerebral activity during immediate transition after birth concurrently showed low crSO2 (<10th percentile), but increased cerebral oxygen extraction (cFTOE>90th percentile). Cerebral monitoring with aEEG and NIRS might provide useful information on the neonates' condition during immediate transition.

Potassium cardioplegia-induced transient asystole may conserve myocardial energy, foster chemical defribrillation, and improve VF arrest outcome. A trial of potassium infusion with or without calcium reversal was conducted to test for improvement in intra-arrest VF waveform and post-ROSC hemodynamics. ⋯ Chemical defibrillation and ROSC are possible post potassium-induced asystole. Potassium followed by calcium reversal, but not potassium alone, led to ROSC and post-ROSC hemodynamics comparable to recommended therapy.
