Application of titanium fixation plates for sternum closure after off-pump coronary artery bypass grafting in elderly patients / 中华老年医学杂志

ABSTRACT

Objective To investigate the role of titanium plate fixation for sternum closure after off-pump coronary artery bypass grafting (OPCABG) in elderly patients.Methods A total of 120 elderly patients who accepted OPCABG were randomly divided into two groups.The control group (n =60) received wire to fix the sternum,and the experimental group (n=60) received titanium plate combined with wire to fix the sternum.The chest closure time,the rate of postoperative incision pain,the rate of sternal dehiscence and sternal re-fixation between two groups were observed and recorded.Results The rates of postoperative incision pain,sternal dehiscence,sternal re-fixation was lower in experimental group than in control group [11.7％(7/60) vs.38.3％(23/60),3.3％(7/60) vs.13.3％(8/60),1.7％(1/60) vs.11.7％(7/60),x2 =11.378,3.927,4.821 respectively all P＜0.05].The chest closure time was longer in experimental group than in control group [(39±5)min vs.(30±2) min,x2 =13.386,P＜0.05].Conclusions Titanium fixation plate combined with wire for sternum closure can increase the stability of sternum fixation,reduce the postoperative pain and sternal dehiscence,and then decrease the risk of sternal re-fixation,but delay sternal closure of OPCABG in the elderly.
