骨盆创伤:隐匿出血风险与团队资源Pelvic Trauma: Occult Bleeding Risk and Team Resources

这不是一张骨盆创伤处置清单,而是一门“先形成问题表征,再逐步获得信息”的临床思维课。学员需要说清已知、可疑、担心、xABCDE 优先级、资源瓶颈和下一次复评。This is not a pelvic-trauma treatment checklist. It is a progressive reasoning lesson: build a problem representation first, then receive new information. Learners state what is known, suspected, feared, prioritized within xABCDE, resource-limited, and due for reassessment.

骨盆创伤:从识别隐匿出血到选择止血路径Pelvic trauma: from hidden bleeding to the right haemorrhage-control pathway

先学会认出危险、正确上骨盆带,再按 WSES 分级和国内共识选择止血路径;学完再进入下方互动病例。Recognise danger, apply the binder correctly, then choose a pathway by WSES grade and Chinese consensus; then try the interactive case.

01 · 为什么危险Why it is dangerous

骨盆像一个能装下大量血液的碗The pelvis is a bowl that can hold a lot of blood

高能量骨盆环损伤可在体表看不到血的情况下导致失血性休克。大部分出血来自骨折面和静脉丛,少部分来自动脉——所以“先关上碗”很重要。High-energy pelvic ring injuries can cause shock with no visible blood. Most bleeding comes from fracture surfaces and venous plexus, a minority from arteries — so close the bowl first.

出血来源Bleeding source

约 85% 来自骨、软组织或大静脉;动脉出血约占少数但常更凶险。About 85% from bone, soft tissue or large veins; arterial bleeding is a minority but often brisker.

合并伤Associated injuries

不稳定骨盆骨折患者中多达 90% 伴其他严重损伤:胸、腹、颅脑、长骨。Up to 90% of unstable pelvic fractures have other significant injuries.

死亡率Mortality

10–15% 到急诊时已休克,其中约三分之一死亡;近期报道死亡率约 32%。10–15% arrive in shock; about one third of them die (recent reports ~32%).

WSES:约 85% 的骨盆出血源自骨、软组织或主要静脉结构;死亡主要由不可控出血和生理衰竭造成。WSES: about 85% of pelvic bleeding originates from bone, soft tissue or major veins; deaths come mainly from uncontrolled bleeding and physiological exhaustion.

02 · 识别Recognise

认出“不稳定”:用数字而不是感觉Define “unstable” with numbers, not feelings

满足下列任一项,就按血流动力学不稳定处理,启动骨盆带、输血与止血资源。Any one of these means haemodynamically unstable: binder, blood and haemorrhage-control resources now.

查体Exam

看会阴/阴囊血肿、下肢短缩外旋、尿道口出血;骨盆挤压分离试验最多一次,怀疑时不做。Look for perineal/scrotal haematoma, shortened externally rotated leg, blood at meatus; spring the pelvis once at most, not at all if suspected.

影像Imaging

抢救室骨盆正位片 + eFAST;稳定者做多期增强 CT 看造影剂外溢。AP pelvis + eFAST in the bay; multiphase contrast CT if stable to look for blush.

别被骗Don’t be fooled

FAST 阴性不能排除腹膜后/骨盆出血。A negative FAST does not exclude retroperitoneal or pelvic bleeding.

中国专家共识(2015):怀疑骨盆骨折且血流动力学不稳定者不应过多搬动,禁忌行骨盆挤压-分离试验,尽早使用骨盆带。Chinese consensus (2015): in unstable patients with suspected pelvic fracture, minimise movement, avoid compression-distraction testing, apply a binder early.

真实照片/影像Real image骨盆带培训:双手定位在大转子水平,再收紧(培训演示,非真实患者)。Binder training: hands locate the greater trochanters before tightening (demonstration, no patient).Sgt. Mykaela Martin · Public domain · Wikimedia Commons

03 · 骨盆带Binder

骨盆带:以股骨大转子为中心,不是髂嵴Pelvic binder: centre on the greater trochanters, not the iliac crests

骨盆带通过减少骨盆容积、稳定骨折端来减少出血。最常见的错误是绑得太高(在腰部/髂嵴),几乎没有作用。A binder reduces pelvic volume and stabilises fragments. The commonest error is placing it too high (waist/iliac crests), where it barely works.

位置Position

触摸双侧大转子,带子中线对准大转子;双膝内旋并拢、用绷带固定膝踝。Palpate both trochanters and centre the binder there; internally rotate and tie knees and ankles.

临时替代Improvised

没有专用骨盆带时,可用床单在同一水平环绕收紧并钳夹固定。Without a device, wrap a sheet at the same level and clamp it.

时间与皮肤Time & skin

尽早过渡到确定性固定;NICE 建议 24 小时内移除(WSES:不超过 24–48 小时),并先定好替代固定;定时查皮肤。Move to definitive fixation early; NICE removes binders within 24 h (WSES: ≤24–48 h) with a replacement plan; check skin.

欧洲指南 R20:怀疑骨盆骨折时院前即辅助使用骨盆带(1C);骨盆环破裂合并失血性休克者立即闭合并稳定骨盆环(1B)。European guideline R20: adjunct pre-hospital binder for suspected pelvic fracture (1C); immediate ring closure and stabilisation in haemorrhagic shock (1B).

展开:指南原文要点与教学提示Expand: guideline points and teaching notes

WSES 提醒:骨盆带过紧或长时间持续压力(>9.3 kPa 超过 2–3 小时)会增加皮肤坏死和压疮风险。WSES warns that over-tightening or continuous pressure (>9.3 kPa for >2–3 h) raises the risk of skin necrosis and pressure ulcers.

04 · 分型Classification

分型:Young-Burgess 看机制,WSES 看生理Classify: Young-Burgess for mechanism, WSES for physiology

Young-Burgess 告诉你力从哪里来、哪里会破;WSES 分级把骨折形态和血流动力学结合起来,直接对应处理路径。Young-Burgess tells you where the force came from and what breaks; WSES combines anatomy with haemodynamics and maps to a pathway.

APCAPC

前后挤压,“开书样”,骨盆容积增大,出血风险高(APC-II/III)。Anteroposterior compression, “open book”: volume increases, high bleeding risk (APC-II/III).

LCLC

侧方挤压,最常见;老年人低能量 LC 也可能大出血(尤其服抗凝药)。Lateral compression, commonest; even low-energy LC can bleed in older adults, especially on anticoagulants.

VS / CMVS / CM

垂直剪切多见于高处坠落,半骨盆上移;混合机制并存。Vertical shear from falls with hemipelvis displacement; combined mechanisms coexist.

WSES 分级中,只要血流动力学不稳定,无论骨折类型均为 IV 级(重度)。In WSES grading, any haemodynamically unstable patient is grade IV (severe), whatever the fracture pattern.

AI 教学插图AI teaching illustration多学科团队:急诊、创伤外科、骨科、介入、麻醉同步决策。MDT: emergency, trauma surgery, orthopaedics, IR and anaesthesia decide together.

05 · 止血路径Haemorrhage control

按路径止血:填塞、栓塞、REBOA 各有位置Follow the pathway: packing, embolisation and REBOA each have a place

不稳定患者不去 CT,而是去能止血的地方。没有 24 小时介入能力的医院,腹膜外骨盆填塞联合外固定是重要选择。Unstable patients go to where bleeding stops, not to CT. Where 24-hour IR is unavailable, preperitoneal packing with external fixation is key.

腹膜外填塞Preperitoneal packing

骨盆出血致不稳定时均应考虑,尤其无介入条件的医院(WSES 1C);须与骨盆稳定联合。Consider in all pelvic-related instability, especially without IR (WSES 1C); combine with stabilisation.

血管栓塞Angioembolisation

CT 见动脉造影剂外溢,或填塞/固定后仍不稳定时考虑。For arterial blush on CT, or persistent instability after packing/fixation.

REBOAREBOA

只是“通往手术或栓塞的桥”,不是确定性止血;Zone III 用于骨盆出血。Only a bridge to surgery or embolisation, not definitive control; Zone III for pelvic bleeding.

WSES:REBOA 被定位为“通往手术的桥梁”;中国共识(2015)也建议极不稳定者在急诊室稳定骨盆、腹膜外填塞和/或主动脉球囊阻断后立即送导管室。WSES positions REBOA as a bridge to surgery; the 2015 Chinese consensus advises stabilisation, packing and/or balloon occlusion in the ED, then straight to angiography for extreme instability.

06 · 合并伤Associated injuries

别只看骨盆:尿道、直肠、阴道和开放伤口Look beyond the bone: urethra, rectum, vagina and open wounds

骨盆骨折常合并泌尿生殖和直肠损伤。开放性骨盆骨折死亡率更高,需要尽早识别和多学科处理。Pelvic fractures often involve genitourinary and rectal injury. Open pelvic fractures carry higher mortality and need early MDT care.

尿道Urethra

尿道口出血、会阴血肿、男性前列腺上移 → 先逆行尿道造影,不盲插导尿管;必要时耻骨上造瘘。Blood at meatus, perineal haematoma, high-riding prostate → retrograde urethrogram before catheter; suprapubic if needed.

直肠/阴道Rectum/vagina

检查有无出血或骨折刺破;开放伤需早期抗生素、清创,必要时粪便转流。Check for blood or penetrating fragments; open injuries need early antibiotics, debridement, possibly diversion.

老年人Older adults

低能量跌倒也可大出血;询问抗凝/抗血小板药并尽早逆转。Low-energy falls can bleed; ask about anticoagulants/antiplatelets and reverse early.

WSES:高等级损伤中胸腹合并伤可达 80%;膀胱、尿道(1.6–25%)、阴道、直肠等损伤在会阴血肿或广泛软组织破坏时应高度怀疑。WSES: thoraco-abdominal injuries in up to 80% of high-grade cases; suspect bladder, urethra (1.6–25%), vagina and rectum with perineal haematoma or major soft-tissue disruption.

WSES 2017 · ATLS 11 Musculoskeletal trauma

骨盆创伤最常见的 4 个错误Four common pelvic trauma mistakes

✕骨盆带绑在腰部髂嵴水平。Binder placed at the waist/iliac crests.

✓以股骨大转子为中心重新放置,并内旋并拢双下肢。Re-centre on the greater trochanters and internally rotate the legs.

EU 2023 R20 · WSES

✕反复挤压骨盆“确认”不稳定。Repeatedly springing the pelvis to “confirm” instability.

✓怀疑即不做挤压分离试验,靠骨盆正位片和 CT 诊断。If suspected, skip springing; diagnose with AP pelvis and CT.

中国共识 2015Chinese consensus 2015

✕FAST 阴性就停止找出血。Stopping the bleeding search after a negative FAST.

✓FAST 看不到腹膜后;持续不稳定按骨盆出血路径处理。FAST misses the retroperitoneum; treat persistent instability as pelvic bleeding.

WSES 2017

✕不稳定患者先送 CT。Sending an unstable patient to CT first.

✓去手术室/杂交手术室或导管室止血;稳定后再做 CT。Go to OR/hybrid OR or angiography; CT once stable.

01

风险从机制与生理开始Start with mechanism and physiology

高能量机制和持续灌注异常需要考虑骨盆及其他隐匿出血来源;避免反复诱发骨盆不稳的检查。High-energy mechanism and persistent perfusion abnormalities warrant assessment of pelvic and other occult bleeding sources; avoid repeated provocative pelvic testing.

02

影像记录检查条件Record imaging conditions

报告束带是否在位、检查时的生理和未回答的问题。表面复位不能独立排除骨盆环损伤。Report binder status, physiology at imaging and unresolved questions. Apparent reduction cannot independently exclude pelvic ring injury.

03

资源与复评同步Coordinate resources and reassessment

骨科、止血、复苏及进一步影像路径按生理与本地资源协同制定,束带移除需团队计划。Coordinate orthopaedic, haemorrhage-control, resuscitation and imaging pathways by physiology and local resources; binder removal requires a team plan.

暂停判断:束带在位 CT 未见异常,但疼痛持续,能结束评估吗?Pause and decide: CT with a binder is unremarkable but pain persists. Can assessment end?

不能。把检查条件、机制和症状一起报告,由团队安排安全的进一步评估;不要自行移除束带来测试。No. Report imaging conditions, mechanism and symptoms together and plan safe further assessment with the team; do not independently remove the binder to test stability.

核对依据、版本与适用范围Check evidence, version and scope

真实公开图用于观察训练;病例与指南各自标明来源,病例报告不能单独建立普遍治疗规则。Public images support observation training. Case reports and guidelines are distinguished; a case report alone cannot establish a general treatment rule. Clinical applicability remains pending teacher review.

说明机制、院前趋势、保护/搬动信息、已完成评估和仍未知内容。State mechanism, prehospital trend, protection/movement information, completed assessment, and remaining unknowns.

A · Assessment

区分已知、可疑和担心;说明 C/E 重点及 A/B/D 和合并伤是否改变排序。Separate known, suspected, and feared; state the C/E focus and whether A/B/D or associated injury changes priority.

R · Resources / Reassessment

说清需要同步的资源、当前瓶颈、下一次患者复评和系统复评责任人。State resources to synchronize, current bottlenecks, and owners of the next patient and system reassessment.

最后练习:用 60 秒完成交接Final practice: deliver a 60-second handover

患者复评Patient reassessment
  • 意识与整体表现Mental status and overall appearance
  • 呼吸与灌注趋势Breathing and perfusion trend
  • 新体征与新症状New findings and symptoms
  • 团队行动后的变化Change after team action
系统复评System reassessment
  • 人员、空间和设备Staff, space, and equipment
  • 影像与下游能力Imaging and downstream capacity
  • 血液与手术/介入资源Blood and surgical/procedural resources
  • 转运与交接瓶颈Transfer and handover bottlenecks

教师提示Instructor Notes

建议节奏Suggested timing

院前信息 6 分钟,问题表征与优先级 10 分钟,信息释放 12 分钟,检查与资源 8 分钟,交接复盘 9 分钟。Prehospital information 6 minutes, representation and priority 10, information release 12, investigations and resources 8, handover debrief 9.

常见误区Common misconception

把没有明显外出血、某项床旁检查未见异常或一个时间点相对稳定,误认为隐匿风险已经被排除。Treating absent obvious external bleeding, a non-revealing bedside test, or one relatively stable moment as exclusion of occult risk.

揭示点Reveal point

每轮先让学员写出“新信息改变了什么”,再显示参考思路;教师不追求唯一答案,而追问理由和复评计划。Before revealing the reference, learners state what changed. The instructor asks for rationale and reassessment rather than one unique answer.

临床判断与关键步骤Clinical decisions and key steps

具体方案;以本院为准;每项数字同时核对人群、阶段和来源。Follow institutional protocols; check population, stage and source with every number.

不稳定骨盆:固定与确定性止血Unstable pelvis: stabilization and definitive control

不稳定定义Instability definition

WSES:SBP<90,或需持续补液/输血/升压药维持;BD>6 mmol/L、SI>1或24 h需4–6 U RBC也是风险依据,单位不可跨国直接折算。以本院规范为准。WSES: SBP below 90 or maintained by ongoing fluids/blood/vasopressors; BD over 6, SI over 1 or4–6 RBC units in24 hours also indicate risk. Do not directly convert national component units. Follow institutional policy.

大转子→分流止血Greater trochanters→control pathway

骨盆带中心位于大转子/耻骨联合水平;无相关肢体禁忌时双膝并拢、踝内旋,避免反复挤压分离试验。同步血液、保温、TXA及其他出血源检查。以本院规范为准。Center the binder at greater trochanters/symphysis level; knees together and internal leg rotation when associated injuries allow. Avoid repeated springing. Coordinate blood, warming, TXA and other-source checks. Follow institutional policy.

骨盆带→动脉出血且不需开腹:血管造影栓塞;需开腹/快速控制:腹膜外填塞+外固定。REBOA Zone III仅受训团队为疑盆腔来源、极不稳定者的过渡,不是所有路径的必经最后一步。以本院规范为准。Binder→arterial bleeding without laparotomy need: AE; laparotomy/rapid control need: preperitoneal packing plus external fixation. ZoneIII REBOA is a skilled-team bridge in extreme instability with suspected pelvic source, not a mandatory final step. Follow institutional policy.

去除也有计划Removal needs a plan

NICE1.2.17:全部骨盆带24 h内去除;不稳定骨折先与骨盆外科确定替代固定。国内旧共识≤36 h条目需作者核对原文,不用较长上限替代现有移除计划。以本院规范为准。NICE 1.2.17 removes all binders within 24 hours, with an alternative stabilization plan for unstable fractures. The older Chinese at-most36-hour clause awaits author original-text verification; do not use it to extend current removal plans. Follow institutional policy.

IJEM 2025 多发伤骨盆骨折研究IJEM 2025 pelvic fracture polytrauma study

本土证据:从队列回到 MDT 问题Local evidence: from cohort to MDT questions

Ding 等,IJEM 2025:32 例多发伤合并骨盆骨折的单中心回顾性研究;报告死亡 3/32(9.4%),胸部合并伤 28/32(87.5%)。Ding et al., IJEM 2025: a single-center retrospective cohort of 32 polytrauma patients with pelvic fractures, reporting 3/32 deaths (9.4%) and 28/32 associated thoracic injuries (87.5%).

教学启示:同时看全身损伤、生理趋势和跨专科接续。方法报告单因素及相关性分析;不能据此证明 MDT 降低死亡,或把 GCS/ISS 解释为已验证的独立因果因素。Teaching implication: integrate whole-body injury, physiological trends and specialty transitions. Reported methods use univariate/correlation analysis; this does not prove that MDT reduces mortality or establish GCS/ISS as independent causal factors.
