2 | METHODS
Patients who were brought to our emergency services due to OHCA and
hospitalized in ICU after a successful CPR were investigated
retrospectively. Successful CPR was defined as acute respond to the CPR
in the emergency department and transfer to the ICU for follow-up.
Patients with trauma, systemic infection, intracranial hemorrhage, major
surgery within the previous 14 days and malignancy were excluded from
the study. Consequently, a total of 102 patients with OHCA were included
in this study. Local ethic committee was approved the study design and
the study was conducted in full accordance with the Declaration of
Helsinki.
Blood samples were obtained routinely immediately after hospital
admission. Complete blood cell (CBC) counts were measured with an
automated blood cell counter. Neutrophil to lymphocyte ratio (NLR) was
calculated as the ratio of neutrophil to lymphocyte. Platelet to
lymphocyte ratio (PLR) was calculated as the ratio of platelet to
lymphocyte. Also, arterial blood gas sampling and biochemical analyses
including serum electrolytes, creatinine, aminotransferases, serum
albumin and CRP was obtained from all patients. CAR was calculated as
the ratio of CRP to the albumin.
Our study population were divided into two groups as follows: survivor
(n = 43) and non-survivor (n = 59) during follow-up. The archive records
of all patients were investigated retrospectively, and baseline
characteristics, blood gas samples and laboratory parameters were
compared between two groups.
