Objectives:
Deep sternal wound infection is a devastating complication of cardiac surgery. In the current era of increasing patient comorbidity, newer techniques must be evaluated in attempts to reduce the rates of deep sternal wound infection.
Methods:
A randomized controlled trial comparing sternal closure with traditional sternal wires in figure-8 formation with the Pioneer cabling system® from Medigroup after adult cardiac surgery was performed.
Results:
A total of 273 patients were enrolled with 137 and 135 patients randomized to sternal wires and cables group, respectively. Baseline characteristics between the two groups were well balanced. Deep sternal wound infection occurred in 0.7% of patients in the wires group and 3.7% of patients in the cables group (absolute risk difference = -3.0%, 95% confidence interval: -7.7 to 0.9%; P = 0.12). Patients in the cables group were extubated slightly earlier than those in the sternal wires group postoperatively (9.7 vs 12.8 h; P = 0.03). There was, however, no significant difference in hospital and follow-up pain scores or analgesia requirements.
Conclusions:
The Pioneer sternal cabling system appears to facilitate early extubation after adult cardiac surgery, but it does not reduce the rate of deep sternal infectionAustralian New Zealand Clinical Trials Registry: ANZCTR-ACTRN12615000973516.
