Central venous access devices (CVAD) are used to facilitate intravenous treatment with coagulation factor concentrates (CFCs) in haemophilia A (HA). Guidelines for perioperative CFC replacement therapy are based on single centre experiences, and the length of replacement therapy varies.
The aim of this study was to evaluate whether haemostasis coverage under four days is as effective and safe as a longer period of haemostatic coverage.
We identified patients with severe HA without inhibitors or major bleeds within one month of the surgery who received their first CVAD. We compared the CFC consumption and bleeds between children with ≤4 and those who received 5-7 perioperative treatment days including the day of surgery. Bleeds were recorded up to 4 days after the end of perioperative haemostatic coverage.
In total, 144 children met the eligibility criteria and were included in the study cohort: 34 had received haemostatic coverage for ≤4 days, while 110 had received 5-7 days of haemostatic coverage. One bleed related to the surgery occurred in both groups.
Overall, the bleeding complications were rare. Haemostatic coverage with CFCs under ≤4 days with elective CVAD insertions was as effective as coverage for ≥5 days.
中央静脉通路装置(CVAD)用于在甲型血友病(HA)患者中方便给予凝血因子浓缩物(CFC)的静脉内治疗。围手术期 CFC 替代治疗的指南基于单中心经验,替代治疗的时间长短不一。
本研究旨在评估 4 天内的止血覆盖是否与更长时间的止血覆盖同样有效和安全。
我们确定了在手术前一个月内没有抑制剂或重大出血且接受首次 CVAD 的重度 HA 患者。我们比较了接受≤4 天和 5-7 天围手术期治疗(包括手术当天)的患儿之间的 CFC 消耗和出血情况。出血情况记录至围手术期止血覆盖结束后 4 天。
共有 144 名患儿符合入选标准并纳入研究队列:34 名患儿接受≤4 天的止血覆盖,110 名患儿接受 5-7 天的止血覆盖。两组均发生 1 例与手术相关的出血。
总体而言,出血并发症罕见。择期 CVAD 植入术的 CFC 止血覆盖≤4 天与覆盖≥5 天同样有效。
