Pre-conditioning with HBO may induce cerebral and cardiac protection in patients undergoing on-pump CABG surgery

Clinical Bottom line:

1. Pre-conditioning with HBO resulted in improved clinical outcomes for patients undergoing 'on-pump' CABG surgery.

2. There were also potential cerebral and cardiac protective effects as determined by proxy outcomes.

3. No protective effects were noted in off-pump CABG

Citation/s:Yang L, Dong H, Chen M et al. Preconditioning with repeated hyperbaric oxygen induces myocardial and cerebral protection in patients undergoing coronary artery bypass graft surgery: a prospective, randomized, controlled clinical trial. Journal of Cardiothoracic and Vascular Anesthesia 2011;25(6):908-916.

Lead author's name and email:Yang Li: lxiong@fmmu.edu.cn

Three-part Clinical Question:For patients undergoing CABG, does the addition of hyperbaric oxygen to standard care confer any myocardial and cerebral protection?

Search Terms:CABG, preconditioning, cardiopulmonary bypass

The Study:Single-blinded randomised controlled trial without intention-to-treat.

The Study Patients:Male patients under 80 years having CAG either on cardiopulmonary bypass or off-pump.

Control group(N = 16; 15 analysed): Full orthodox pre-operative care for CABG. No sham treatment.

Experimental group(N = 15; 14 analysed): As above, but patients were given 5 daily sessions of HBOT at 2ATA breathing 100% ATA for 70 minutes.

The Evidence:

Comments:

1. Exclusion of female subjects and small numbers may limit external validity of the study

2. Only 2 biochemical markers were analyzed to measure cerebral injury; it may not be fully representative of actual cerebral damage.

3. Early post-operative outcomes may not be representative of long-term morbidity and mortality

4. Values of mean and standard deviation were not provided for non-significant results in off-pump patients.
