Abstract: Background Despite new improvements on cardiopulmonary resuscitation (CPR), brain damage is very often after resuscitation. Objective To assess the prognostic value of cerebral oxygen saturation measurement (rSO 2 ) for assessing prognosis on patients after cardiopulmonary resuscitation. Design Retrospective analysis. Measurements and results We analyzed 25 post-CPR patients (12 female and 13 male). All the patients were cooled to a target temperature of 33–34 °C. The Glascow Coma Scale (GCS), Corneal Reflexes (CR), Pupillary Reflexes (PR), arterial Base Excess (BE) and rSO 2 measurements were taken on admission. The rewarming GCS, CR, PR, BE and rSO 2 measurements were made after the patient's temperature reached 36 °C. Results In survivors, the baseline rSO 2 value was 67.5 (46–70) and the percent difference between baseline and rewarming rSO 2 value was 0.03 (0.014–0.435). In non-survivors, the baseline rSO 2 value was 30 (25–65) and the percent difference between baseline and rewarming rSO 2 value was 0.031 (−0.08 to −20). No statistical difference was detected on percent changes between baseline and rewarming values of rSO 2. Statistically significant difference was detected between baseline and rewarming GCS groups ( p = 0.004). No statistical difference was detected between GCS, CR, PR, BE and rSO 2 to determine the prognosis. Conclusion Despite higher values of rSO 2 on survivors than non-survivors, we found no statistically considerable difference between groups on baseline and the rewarming rSO 2 values. Since the measurement is simple, and not affected by hypotension and hypothermia, the rSO 2 may be a useful predictor for determining the prognosis after CPR.
