Brief Summary

Median sternotomy has been the standard incision for coronary artery bypass grafting (CABG) in patients undergoing surgery for coronary artery disease. Given the increasing risk profile of contemporary cardiac surgery patients, sternal complications are subject to increase concomitantly. Despite advances in many areas of cardiac surgical procedures, innovation in sternal closure technique has been lacking and postoperative complications remain. In this study, the investigators aim to assess the effectiveness of using a novel osteoconductive biologic bone cement (KryptoniteTM, Doctors Research Group Inc.) as an adjunct to conventional sternal closure in post CABG patients having median sternotomy. The outcomes of interest for this study will include: pain, discomfort, lung function, wound healing and analgesic use. The investigators assume that the use of KryptoniteTM will decrease postoperative pain leading to improvement in postoperative lung function. This may also lead to improvement in patient recovery and decrease in postoperative complications. The investigators will undertake a single-blinded randomized, controlled study consisting of patients undergoing elective coronary artery bypass grafting (CABG) randomly assigned to either Group A (usual closure with stainless steel wires) or Group B (usual closure with stainless steel wires plus application of bone cement). Each group will consist of 64 patients in a total of 128 patients. Lung function data using a spirometer will be collected preoperatively and 3rd and 5th postoperative days as well as in outpatient clinic. Pain data will be collected on the 1st to 5th postoperative days.

Eligibility Criteria

Age50 Years - 79 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients presenting for elective isolated on-pump CABG surgery using left internal mammary artery as a graft, through first-time median sternotomy aged between 50 and 79, who provide informed consent to participate.

You may not qualify if:

  • Patients who: are in emergent need for surgery, have had prior median sternotomy, are not applicable to the use of left internal mammary artery as a graft, are at high-risk of early post-operative bleeding requiring reopening of chest (taking anti-platelet medication within 24 hours of surgery), have had previous radiotherapy to the chest, present in a clinical preoperative state that suggests a prolonged recovery (e.g., other concurrent illness such as significant respiratory disease or renal failure requiring dialysis, current use of steroids, residence in a long-term care facility, current substance abuse), or present with cognitive impairment (e.g., confusion, dementia, Alzheimer's disease) that would preclude completion of survey questions, will be ineligible.
