We report the life-saving administration of thrombolysis during cardiopulmonary resuscitation in a patient with recent intracerebral haemorrhage. A 53-year-old male with intracerebral haemorrhage was admitted to the intensive care unit. On the 24th day of treatment he suffered cardiac arrest with pulseless electrical activity. ⋯ Permanent restoration of a spontaneous rhythm was feasible only after administration of systemic thrombolysis with recombinant tissue plasminogen activator. Neurological examination and a computed tomogram of the brain did not show rebleeding. We conclude that under extreme circumstances absolute contraindications to thrombolysis should be weighed against the potential benefit.

Randomized Controlled Trial Comparative Study
The size 1 LMA-ProSeal: Comparison with the LMA-Classic during pressure controlled ventilation in a neonatal intubation manikin.
The classic laryngeal mask airway (cLMA) has been demonstrated to be effective for airway management during neonatal resuscitation. However, high airway pressures, when required, cannot be achieved with this device. A neonatal prototype of the LMA-ProSeal (PLMA), which might improve the oropharyngeal leak pressure, has recently been produced. The airway sealing pressures of the cLMA and the PLMA were compared in a neonatal manikin. ⋯ The neonatal PLMA allows higher airway pressure ventilation than the cLMA, in a neonatal intubation manikin. If confirmed clinically, this may have important implications during neonatal resuscitation when high airway pressures are required.

Randomized Controlled Trial
Hypertonic saline during CPR: Feasibility and safety of a new protocol of fluid management during resuscitation.
In experimental studies infusion of hypertonic saline during cardiopulmonary resuscitation (CPR) increased resuscitation success rate and improved myocardial and cerebral reperfusion during CPR. We tested the feasibility and the safety of this new therapeutic measure in a randomised, preclinical pilot study. ⋯ HHS after CA is feasible and safe and might improve short term survival after CPR. However, whether giving HHS could be a useful measure to increase resuscitation success after out-of-hospital CA requires a larger preclinical trial.

Providing cardiopulmonary resuscitation (CPR) to a patient in cardiac arrest introduces artefacts into the electrocardiogram (ECG), corrupting the diagnosis of the underlying heart rhythm. CPR must therefore be discontinued for reliable shock advice analysis by an automated external defibrillator (AED). Detection of ventricular fibrillation (VF) during CPR would enable CPR to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. ⋯ CPR artefacts were added to the ECG signals and four degrees of corruption were tested. Mean sensitivities of 97.83%, 98.27%, 98.32% and 98.02% were achieved, producing sensitivity increases of 28.44%, 49.75%, 59.10% and 64.25%, respectively, sufficient for ECG analysis during CPR. Although satisfactory and encouraging sensitivity values have been obtained, further clinical and experimental investigation is required in order to integrate this type of artefact suppressing algorithm in current AEDs.

We reported previously that therapeutic hypothermia with extracorporeal lung and heart assist (ECLHA) improved neurological outcome after 15 min cardiac arrest (CA) in dogs, although 45 min was needed to achieve hypothermia. We now investigate whether rapidly induced hypothermia with ECLHA (RHE) would result in a better outcome than slowly induced hypothermia with ECLHA (SHE) in dogs. ⋯ Rapid hypothermic induction might be an important factor to improve neurological outcomes in prolonged CA models.
