摘要
Objective: Aim of this study was to examine immature granulocyte/total granulocyte (IG/TG) ratio for prediction of return of spontaneous circulation (ROSC) and early mortality in post cardiac arrest survivors. Methods: The study was carried out prospectively between January 2021 and January 2022. Non-traumatic out-of-hospital cardiac arrest (OHCA), over the age of 18 and non-pregnant were included. Patients’ whose IG levels were not studied, with hematological disease and who receiving immunosuppressive therapy were excluded. A palpable pulsation of the main arteries for at least 15 minutes was considered ROSC. Data were compared between the<4 hour and ≥4 hour survival groups and patients with and without ROSC. Results: Total of 254 OHCA patients were included in the study. ROSC was achieved in 84 (33.1%) of these patients and 170 (66.9%) patients were died. There were 28 patients (33.3%) with survival of <4 hours and 56 patients (66.7%) with survival of ≥4 hours in patients with ROSC. The IG count and IG/TG ratio did not differ significantly between the ROSC groups and between the groups separated by survival time (P>0.05). Conclusion: We found no significant differences between subgroups defined according to survival duration. Similarly, no differences found between OHCA patients with and without sustained ROSC.
