Cardiac Arrest During and/or Resulting From A Procedure

Brief summary
During CPR bag-valve mask ventilation is difficult for basically skilled rescuers. Ventilation may be inefficient or with too high pressures result in stomach inflation and aspiration. Studies suggest that with a supraglottic airway device, such as the laryngeal tube, a basically skilled rescuer may ventilate more efficient and also safer. No prehospital study has been conducted comparing laryngeal tube and bag-valve mask ventilation during CPR. Thus, this study intends to compare ventilation with laryngeal tube and bag-valve mask performed by paramedics during CPR.
Detailed description
During CPR bag-valve mask ventilation is difficult for basically skilled rescuers. Ventilation may be inefficient or with too high pressures result in stomach inflation and aspiration. Studies suggest that with a supraglottic airway device, such as the laryngeal tube, a basically skilled rescuer may ventilate more efficient and also safer. No prehospital study has been conducted comparing laryngeal tube and bag-valve mask ventilation during CPR. This study intends to compare ventilation with laryngeal tube and bag-valve mask performed by paramedics during CPR. This study may provide information if paramedics in an emergency should ventilate as they do traditionally with bag-valve mask ventilation or if they should ventilate with a laryngeal tube.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Efficient ventilation | From start of paramedic ventilating the patient during CPR until emergency physician takes over ventilation or patient breathes again spontaneously after return of spontaneous circulation (ROSC) | Does chest rise clearly during CPR? Thus efficient ventilation will be assessed during CPR, which may last on average between 20 and 60min. Therefore efficient ventilation will be assessed from starting CPR at 0min to 20min or rarely 60min or longer. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Aspiration | From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 1 month after enrollment of the last patient at August 30th 2014 | Aspiration will be assessed 24hrs after CPR with bronchoscopy |
