Abstract:
Objective To establish a less-damage method for tracheal intubation so as to improve the quality of post-cardiac arrest syndrome.Methods Thirty rabbits wvere divided into 3 groups of 10 rabbits each according to the random number table:group A receiving direct endotracheal intubation after anesthesia,Group B separation of cervical tissue and retrograde tracheal intubation after anesthesia and Group C percutaneous retrograde tracheal intubation after anesthesia.After the intravenous injection of forskolin,cardiac arrest was induced by endotracheal tube clamping.After 5 minutes of untreated arrest,conventional cardiopulmonary resuscitation was initiated.Changes in arterial pressure,occurrence of post-resuscition syndrome and survival time were examined in all groups.Results Groups A,B and C showed 40％,60％ and 80％ success rate in cardiopulmonary resuscitation (P ＜ 0.01) and animal survival time of 23.4 hours (11.6-35.8 hours),62.7 hours (29.4-88.6 hours) and 79.5 hours (40.9-118.2 hours) (P ＜ 0.01).Conclusions Percutaneous retrograde tracheal intubation is suitable to increase cardiopulmonary resuscitation rate and survival rate in rabbits with post-cardiac arrest.The model has good stability and repeatability and can be used for study of post-cardiac arrest syndrome.
