Abstract 163: Monitoring System of Regional Cerebral Oxygen Saturation During Pre-hospital Cardiopulmonary Resuscitation
Objective: We aimed to establish the monitoring system of rSO2 in patients with cardiopulmonary arrest (CPA) from pre-hospital, and clarify the changes in rSO2 during cardiopulmonary resuscitation (CPR).
Method: We measured rSO2 in CPA patients who are transferred by the emergency response vehicle of Nagasaki University Hospital. We developed a portable rSO2 monitor (HAND ai TOS) which is small enough to carry during the pre-hospital treatment. rSO2 sensor was attached to the forehead of patients, and monitored continuously during treatment and transfer.
Result: There was no difficulty for treatment and transfer in monitoring rSO2. Mean rSO2 on arrival is 46.4±3.56% (n=6, Mean Age 77, M:F=1:2). Mean rSO2 after return of spontaneous circulation (ROSC) is 68.8±1.42% (n=3, Mean Age 83.3, M:F=2:1). ROSC showed the significantly higher increase in rSO2 than CPR (68.8±1.42 vs 46.2±3.20, p<0.05). Mechanical CPR showed more increase in rSO2 than manual CPR. Figure shows the representative rSO2 change after ROSC.
Conclusion: We developed the rSO2 monitoring system in pre-hospital CPR. rSO2 changed in response to the pre-hospital treatment, which may contribute to the quality improvement in pre-hospital CPR.
