Abstract
Inflation and oesophageal pressures were recorded simultaneously during bag and mask resuscitation of 9 asphyxiated babies. After half a minute of standard inflation pressures, higher pressures were applied for at least 5 inflations by occluding the blow-off valve. No air entered the oesophagus until a high mean inflation pressure of 5.4 kPa was exceeded. These findings were confirmed in 4 fresh stillborn babies studied similarly. We conclude that resuscitation using bag and mask, applying pressures less than 3.5 kPa, should not lead to gastric distension.
摘要
在对9名窒息婴儿进行面罩气囊复苏过程中，同时记录充气压力和食管压力。在标准充气压力维持半分钟后，通过关闭排气阀施加更高压力至少进行5次充气。直到平均充气压力超过5.4 kPa时，才有空气进入食管。在4名采用类似方法研究的新鲜死产婴儿中证实了这些发现。我们得出结论，使用面罩气囊进行复苏时，施加小于3.5 kPa的压力不应导致胃扩张。
