Comparison of figure-of-8 wiring or simple straight-wiring technique assessed by the frequency of early noninfectious sternal dehiscence.
Observational register study with 7835 patients having sternal closure with figure-of-8 steel wires was compared with 2122 patients, where the sternotomy was closed by simple interrupted straight wires. The endpoint was the rate of early (within 30 days) sterile sternal dehiscence.
Fourteen patients (0.66%) with single wires and five patients (0.06%) with figure-of-8 wires underwent re-operation for nonmicrobial sternal disruption (p < 0.0001). The median time-point for re-intervention was 6 days for both groups. In more than 6000 patients, the sternotomy was closed with five figure-of-8 wires without dehiscence in any of them.
In a large cohort of consecutive cardiac operations, it was found that sternal closure with figure-of-8 wires is better than closure with simple interrupted wires.
比较采用 8 字布线或单纯直布线技术时早期非感染性胸骨裂开的频率。
对 7835 例采用 8 字钢丝行胸骨闭合的患者与 2122 例采用单纯间断直钢丝行胸骨切开术的患者进行观察性登记研究。终点是早期（30 天内）无菌性胸骨裂开的发生率。
14 例（0.66%）单根钢丝患者和 5 例（0.06%）8 字钢丝患者因非微生物性胸骨破裂而行再次手术（p < 0.0001）。两组的再次干预中位时间点均为 6 天。在超过 6000 例患者中，5 根 8 字钢丝闭合胸骨均未发生裂开。
在一项大型连续心脏手术队列中，发现 8 字布线的胸骨闭合优于单纯间断钢丝。
