Current status of establishing a venous line in CPA patients by Emergency Life-Saving Technicians in the prehospital setting in Japan and a proposal for intraosseous infusion

Table 1 Return of spontaneous circulation (ROSC) and 1-month survival rate after CPA with or without adrenaline administration

	ROSC (n = 8,136)	Non ROSC (n = 104,302)	1-month survival rate after CPA (n = 5,907)	Non survival (n = 106,538)
Adrenaline administration	1,570 (18.5%)***	6,651 (81.5%)	427 (5.2%)	7,737 (94.8%)
No adrenaline administration	6,566 (6.3%)	97,691 (93.7%)	5,480 (5.3%)	98,801 (94.7%)

ROSC and 1-month survival rate after CPA for adrenaline administration were compared using the chi-square test.
The rate of ROSC was significantly higher in the group with adrenaline administration compared to the group without adrenaline administration; however, there was no difference in the 1-month survival rate. ***p < 0.001 in chi-square test.
