About this study

Official title: Retroperitoneal Packing or Angioembolization for Hemorrhage Control of Pelvic Fractures - Quasi-randomized Clinical Trial of 56 Hemodynamically Unstable Patients With Injury Severity Score ≥ 33

This study is designed to answer whether minimal invasive vessel clotting (angioembolization) or open surgery (retroperitoneal packing) is more effective for pelvic fractures with massive bleeding. Patients admitted at daytime (7am-5pm) are treated with angioembolization while patients admitted at nighttime (5pm to 7am) are treated with open surgery.

Read the detailed description

In patients with pelvic fracture uncontrollable bleeding is the major cause of death within the first 24h after injury. Early hemorrhage control is therefore vital for successful treatment. Nowadays, recommended techniques for hemorrhage control in pelvic fractures are retroperitoneal pelvic packing and angioembolization, dependent upon the available technical staff and resources and the condition of the patient.

Retroperitoneal pelvic packing, on the one hand, is a relatively simple method in controlling pelvic hemorrhage even with limited resources. Since 89% of pelvic fracture hemorrhage originates from venous bleeding, fracture stabilization and compressive hemostasis by packing is a reasonable approach. Angioembolization, on the other hand, has great high effectiveness with regard to bleeding control, but requires an angiography suite and technical staff. Since hemostasis of retroperitoneal venous bleeding often can be achieved by external pelvic fixation, angioembolization is required for the 11% arterial bleedings which are hard to control by packing. Even though many authors see both methods as complements, time is crucial in the multitrauma setting and the severely injured patient does not tolerate multiple interventions well. Until now good predictors for treatment choice are unavailable, and management of hemodynamically unstable pelvic fractures remains a matter of debate.

This study was designed to answer following questions:

  • Is retroperitoneal pelvic packing or angiography superior with regard to in-hospital mortality, complications, required secondary procedures, or post-intervention blood loss?
  • Which of these methods is the more rapid intervention in the acute setting?

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PACKINGProcedure or surgery

    Also called retroperitoneal pelvic packing

    By retroperitoneal access the space in front of the pelvic fracture is compressed with surgical towels, which stops effectively venous bleeding

  • ANGIOProcedure or surgery

    Also called angioembolization

    Using en endovascular approach, bleeding arteries are identified and clotted using embolizing agents, or coils.

Study groups in NCT02535624
Study groupRoleWhat they receive
ANGIOActive comparatorPatients with persistent hemodynamic instability (systolic blood pressure (SBP) <90 mmHg after the transfusion of 4 packed red blood cell (PRBC) units in the emergency department) were taken urgently to the angiography suite for pelvic angiography. These patients had to tolerate transfer to the suite. Patients receiving primarily angioembolization therapy were defined as the ANGIO group.
Receives: Procedure: ANGIO
PACKINGActive comparatorIndication for pelvic packing was persistent SBP<90 mmHg during the initial resuscitation period with 3000 ml of intravenous (IV) crystalloids and transfusion of 4 PRBC units. These patients were treated primarly with retroperitoneal packing, while angioembolization OR staff was unavailable (5pm-7am), and were defined as the PACK group.
Receives: Procedure: PACKING

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants deceased occurring in-hospital during or after treatment with packing or embolization

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

Secondary outcomes (6)
  1. Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

  2. Number of postoperative packed red blood cell units administered for each participant

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

  3. Number of participants which required a secondary procedure (PACKING or ANGIO) after the primary intervention (PACKING or ANGIO)

    Packing for ANGIO and angioembolization for PACKING.

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

  4. Time from admission (in minutes) to treatment (PACKING or ANGIO) for each participant

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

  5. Procedural/surgical time (in minutes) for each participant

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

  6. Days on ICU for each participant

    Measured: participants will be followed for the duration of hospital stay, an expected average of 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing PACKING and ANGIO in people with Shock, Hemorrhagic and Fractures, Bone, run by Uppsala University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants deceased occurring in-hospital during or after treatment with packing or embolization (time frame: participants will be followed for the duration of hospital stay, an expected average of 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02535624, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2017.
