Zusammenfassung
Hintergrund
Eine präklinische transtracheale Ventilation über eine kleinlumige Punktionskanüle kann in einer „Cannot-intubate-cannot-ventilate-Situation“ lebensrettend sein. Ein selbst zusammengestelltes Notfallset, bestehend aus einem Dreiwegehahn, der zwischen eine transtracheale Punktionskanüle und eine Sauerstoffquelle eingebaut wird, wurde im Tierexperiment mit einem handgesteuerten Jetgenerator verglichen.
Material und Methoden
An 10 narkotisierten Schweinen (18–35 kgKG) wurde eine kleinlumige Punktionskanüle transtracheal platziert und eine Teilobstruktion des Atemwegs etabliert. Die Tiere wurden in zufälliger Reihenfolge für je 15 min mithilfe eines handgesteuerten Jetgenerators und des Notfallbestecks ventiliert.
Ergebnisse
Mit beiden Gerätschaften konnte bei allen Tieren eine suffiziente Oxygenierung und Ventilation erzielt werden.
Schlussfolgerung
Die Effektivität des selbst zusammengestellten Notfallsets ist mit der eines handgesteuerten Notfalljetgenerators vergleichbar.
Abstract
Introduction
Prehospital transtracheal ventilation via a needle cricothyroidotomy may be lifesaving in cannot-intubate-cannot-ventilate situations. A self-made device consisting of a three-way stopcock placed between a transtracheal airway catheter and an oxygen supply was constructed and the effectiveness of the device was compared with a hand-triggered emergency jet generator in animal experiments.
Materials and methods
An emergency transtracheal airway catheter was inserted into the trachea of 10 anesthetized pigs (18–35 kgbw) and a situation of partial expiratory airway obstruction was established. All pigs were ventilated in a randomized order via the transtracheal airway catheter with the hand-triggered emergency jet injector and the self-made device for 15 min each.
Results
With both devices satisfactory oxygenation and ventilation was achieved in all animals.
Conclusions
The efficacy of the self-made device during the experiment was comparable with the efficacy of the hand-triggered emergency jet injector.
