当患者发生呼吸、心跳骤停时,首要的任务是即刻进行心肺复苏,即有效地人工呼吸和胸外按压,使得呼吸及循环得以重建,恢复有效微循环,使重要脏器获得再灌注,同时积极保护大脑,为大脑功能的恢复做好准备。但如果建立有效人工呼吸、循环所用时间超过4~6min将发生大脑神经不可逆损害〔1〕。因此要求抢救人员熟练掌握心肺复苏技术,在有限的时间内重建有效呼吸和循环。胸外按压对临床医护人员来讲相对容易,而气管插管则要求较高的技术,若反复插管或者插管过程中耽搁胸外按压,耽误时间,从而降低复苏成功率。为了探索喉罩和常规气管插管2种方法,何种方法更快
When the patient is breathing, cardiac arrest, the primary task is immediate cardiopulmonary resuscitation, that is, artificial respiration and chest compression, respiration and circulation can be rebuilt, to restore effective microcirculation, reperfusion of vital organs, at the same time Actively protect the brain and prepare for recovery of brain function. However, if the establishment of effective artificial respiration, the cycle of more than 4 ~ 6min will occur irreversible nerve damage [1]. Rescue workers are therefore required to master cardiopulmonary resuscitation techniques to reconstruct effective respiration and circulation within a limited time frame. Thoracic compression is relatively easy for clinical staff, and tracheal intubation requires a higher technology, if repeated intubation or intubation in the process of chest compression, delay time, thereby reducing the success rate of recovery. In order to explore the laryngeal mask and conventional tracheal intubation two methods, which method is faster
