We aimed to create a system for monitoring of regional cerebral oxygen saturation (rSO ) in patients with prehospital cardiopulmonary arrest and clarify the changes in rSO during cardiopulmonary resuscitation.
We measured rSO in cardiopulmonary arrest patients who were transferred by the emergency response vehicle of Nagasaki University Hospital. We developed a portable rSO monitor (HAND ai TOS), which is small enough to carry during prehospital treatment. The sensor is attached to the forehead of the patient and monitors rSO continuously during treatment and transfer.
No difficulties were experienced in monitoring rSO during patient treatment and transfer. Median time (interquartile range) from the emergency medical service call to emergency response vehicle arrival was 15.0 min (11.0-19.5 min). Median rSO on emergency response vehicle arrival at the scene was 46.3% (44.0-48.2%) ( = 9; median age, 74.0 years; four men, five women). Median rSO showed significant increase within 5 min after return of spontaneous circulation ( = 6, 46.6% versus 58.7%, < 0.05). There was no significant increase in rSO during prehospital cardiopulmonary resuscitation until return of spontaneous circulation was established.
We developed an rSO monitoring system for use during prehospital cardiopulmonary resuscitation. The monitoring system showed a significant increase in rSO after return of spontaneous circulation, whereas there was no significant increase in rSO during cardiopulmonary resuscitation after intubation but before return of spontaneous circulation.
我们旨在创建一个用于监测院前心肺骤停患者局部脑氧饱和度(rSO₂)的系统,并阐明心肺复苏期间rSO₂的变化情况。
我们对由长崎大学医院急救车转运的心肺骤停患者测量了rSO₂。我们开发了一种便携式rSO₂监测仪(HAND ai TOS),其体积小到足以在院前治疗期间携带。该传感器附着于患者前额,在治疗和转运过程中持续监测rSO₂。
在患者治疗和转运期间监测rSO₂未遇到困难。从急救医疗服务呼叫到急救车到达的中位时间(四分位间距)为15.0分钟(11.0 - 19.5分钟)。急救车到达现场时的rSO₂中位数为46.3%(44.0 - 48.2%)(n = 9;中位年龄,74.0岁;4名男性,5名女性)。自主循环恢复后5分钟内rSO₂中位数显著升高(n = 6,46.6%对58.7%,P < 0.05)。在建立自主循环之前,院前心肺复苏期间rSO₂无显著升高。
我们开发了一种用于院前心肺复苏期间的rSO₂监测系统。该监测系统显示自主循环恢复后rSO₂显著升高,而在插管后但自主循环恢复前的心肺复苏期间rSO₂无显著升高。
