摘　　要：Background:Anoxic brain injuries represent the main determinant of poor outcome after cardiac arrest(CA).Large animal models have been described to investigate new treatments during CA and post-resuscitation phase,but a detailed model that includes extensive neuromonitoring is lacking.Method:Before an electrically-induced 10-minute CA and resuscitation,46 adult pigs underwent neurosurgery for placement of a multifunctional probe(intracranial pressure or ICP,tissue oxygen tension or PbtO_(2) and cerebral temperature)and a bolt-based technique for the placement and securing of a regional blood flow probe and two sEEG electrodes;two modified cerebral microdialysis(CMD)probes were also inserted in the frontal lobes and accidental misplacement was prevented using a perforated head support.Result:42 animals underwent the CA procedure and 41 achieved the return of spontaneous circulation(ROSC).In 4 cases(8.6%)an adverse event took place during preparation,but only in two cases(4.3%)this was related to the neurosurgery.In 6 animals(13.3%)the minor complications that occurred resolved after probe repositioning.Conclusion:Herein we provide a detailed comprehensive neuromonitoring approach in a large animal model of CA that might help future research.
