Aim: We assessed out-of-hospital cardiac arrest patients' cerebral oxygenation during cardiopulmonary resuscitation (CPR) using near infrared spectrophotometry (NIRS). We evaluated the relation between a rise in patients' cerebral saturation values between the start and end of CPR and return of spontaneous circulation. Materials and methods: Twenty-three patients with unwitnessed out-of-hospital cardiac arrest and brought to our emergency department by emergency ambulance were evaluated. Cerebral saturations from time of start of CPR were measured using NIRS. CPR was performed for a maximum of 30 min. the relation between cerebral saturations in patients with or without return of spontaneous circulation was then evaluated. Results: Twenty-three patients, 12 (52.2%) female and 11 (47.8%) male, with a mean age of 64.09 +/- 13.66 were included. A correlation was determined between a rise in cerebral saturation measured throughout CPR and the return of spontaneous circulation (P < .001). Conclusion: Patients whose cerebral saturation values measured with NIRS rise during CPR have a higher post-resuscitation survival rate. Monitoring of patients during CPR with this non-invasive technique may be a good method for predicting return of spontaneous circulation. Published by Elsevier Inc.
