Preconditioning With Hyperbaric Oxygen in Cardiovascular Surgery

Status Completed

Clinical Trial Summary

Animal studies have shown that preconditioning with hyperbaric oxygen can induce central nervous system and heart ischemic tolerance. This study was designed to determine the protective effect of hyperbaric oxygen preconditioning on brain and myocardium ischemia-reperfusion injury during coronary artery bypass graft surgery.

Clinical Trial Description

60 patients scheduled to undergo coronary revascularization were recruited for this trial. Exclusion criteria included Emergency operation, age older than 80 years, learning difficulty, previous cerebrovascular disease, visual or hearing impairment, history of pneumothorax, Claustrophobia, middle ear disease, EF < 35%. Patients were randomized either to the control group or hyperbaric oxygen group. The laboratory analysis of markers included S100B, NSE and troponin I. The assessment of cognitive dysfunction was performed 5 days before surgery and 7 days after surgery and haemodynamic measurements, length of stay in ICU, length of stay in hospital post-operation were recorded. ;
