Intra-aortic balloon pump requirement, use of ≥2 inotropic agents, post-operative myocardial infarction and need for post-operative haemodialysis are independent risk factors for patients undergoing open heart surgery. Selection of methods for protecting the myocardium and renal functions during the intra-operative period would reduce the duration of ICU stay.

It seems that apolipoprotein E epsilon4 allele may not affect neurobehavioral status in the intermediate period after on-pump coronary artery bypass grafting.

Infiltration of the median sternotomy incision and the mediastinal tube insertion sites with 0.25% levobupivacaine in addition to morphine patient-controlled analgesia was found to be effective in reducing postoperative morphine consumption when compared with morphine patient-controlled analgesia alone during the initial 24 h after cardiac surgery.

In proximal aortic operations requiring prolonged periods of cerebral protection, the mortality and neurological morbidity are not determined by the type of cerebral protection method only. Factors like hypertension and diabetes may play a role in the development of temporary neurological dysfunction.

The neuromuscular effects of 0.6 mg kg(-1) rocuronium under propofol anaesthesia were markedly prolonged in young and elderly renal failure patients compared to patients with normal renal function, and also in elderly patients with normal renal function compared with young adults.
