Comparison between External Fixation and Pelvic Binder in Patients with Pelvic Fracture and Haemodynamic Instability who Underwent Various Haemostatic Procedures

Haemostatic procedures such as preperitoneal pelvic packing (PPP), pelvic angiography (PA), and internal iliac artery ligation are used for haemorrhage control in pelvic fracture patients with haemodynamic instability. Pelvic external fixation (PEF) and pelvic binder (PB) are usually applied with haemostatic procedures to reduce the pelvic volume. This study aimed to compare the clinical outcomes between patients who underwent PEF and PB. Among 173 patients with pelvic fracture admitted to the emergency room of three regional trauma centres between January 2015 and December 2018, the electronic charts of haemodynamically unstable patients were retrospectively analysed. Among 92 patients included in the analysis, 21 patients underwent PEF and 71 patients underwent PB. There were significant differences in tile classification and laparotomy between the PEF and PB groups (p = 0.018 and p = 0.046). PPP tended to be more frequently preformed in the PEF group (p = 0.074), whereas PA tended to be more commonly performed in the PB group than in the PEF group (p = 0.058). After propensity score matching to adjust for differences in patient characteristics and adjunct haemostatic procedure, there was a significant difference in haemorrhage-induced mortality between the PEF and PB groups (0% vs 25%, p = 0.047). Kaplan–Meier curve analysis also showed a significant difference in haemorrhage-induced mortality between the two groups (log-rank test, p = 0.020). Among the volume reduction procedures performed with other haemostatic procedures in patients with pelvic fracture and haemodynamic instability, PEF significantly reduced haemorrhage-induced mortality compared to PB.

Successful management of perimortem cesarian section with two types of pelvic packing; a case report

Perimortem cesarean is rare and one of the worst possible scenarios in obstetrics. Multidisciplinary approach and speed are extremely important. Pelvic packing in massive postpartum hemorrhages is a method which obstetricians do not commonly use. The patient who had cardiac arrest during travail was successfully managed with a peripartum hysterectomy and two different types of pelvic packing after perimortem cesarean. The mother and baby were healthily discharged. Fetal and maternal survival after perimortem cesarean is quite low. The most important factor determining survival is speed. Pelvic packing is effective in postpartum unstoppable bleeding.

Place of preperitoneal pelvic packing in severe pelvic traumatisms: About 20 cases performed in a French military level one trauma center

BackgroundThe overall mortality of hemodynamically unstable pelvic fractures is high. Hemorrhage triggers off the Moore lethal triad. Hemostatic management during the golden hour is essential. Combined with pelvic stabilisation, preperitoneal pelvic packing (PPP) is proposed to control venous and bony bleeding, while arterioembolisation can stop arterial bleeding. No international consensus has yet prioritized these procedures. The aim of this study was to analyse a serie of PPP in a military level one trauma center and propose an algorithm for hemodynamically unstable pelvic traumas regardless of the military facility.MethodFrom January 2010 to December 2020, every patient from our military institution with a hemodynamically unstable pelvic fracture underwent PPP combined with pelvic stabilisation. Before 2012 data were retrospectively collected from database (PMSI), after 2012 data were prospectively recorded in our polytrauma database and retrospectively analysed. The care algorithm applied focused on hemodynamic status of polytraumatised patients on admission. Primary criteria were early hemorrhage-induced mortality (<24h) and overall mortality (<30d). Secondary criteria were systolic blood pressure (SBP) and red blood cells (RBC) units administered.Results20 patients with a pelvic fracture had a PPP. Mean age was 49,65 +/-23,97 years and median ISS was 49 (31; 67). The decrease of blood transfusion and increase of SBP between pre- and postoperative values were statistically significant. Eight patients (40%) had postoperative arterial pelvic blush and 7 patients were embolised. The early mortality by refractory hemorrhagic shock was 25% (5/20). Overall mortality at 30 days was 50% (10/20).ConclusionPPP is a quick, easy, efficient and safe procedure. It can control venous, bony and sometimes arterial bleeding. PPP is part of damage control surgery and we propose it in first line. Angio-embolization remains complementary. Besides, PPP is the only means available in precarious conditions of practice, notably in military forward units.

Emergency Management of Pelvic Bleeding

Pelvic trauma continues to have a high mortality rate despite damage control techniques for bleeding control. The aim of our study was to evaluate how Extra-peritoneal Pelvic Packing (EPP) and Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) impact the efficacy on mortality and hemodynamic impact. We retrospectively evaluated patients who sustained blunt trauma, pelvic fracture and hemodynamic instability from 2002 to 2018. We excluded a concomitant severe brain injury, resuscitative thoracotomy, penetrating trauma and age below 14 years old. The study population was divided in EPP and REBOA Zone III group. Propensity score matching was used to adjust baseline differences and then a one-to-one matched analysis was performed. We selected 83 patients, 10 for group: survival rate was higher in EPP group, but not significantly in each outcome we analyzed (24 h, 7 day, overall). EPP had a significant increase in main arterial pressure after procedure (+20.13 mmHg, p < 0.001), but this was not as great as the improvement seen in the REBOA group (+45.10 mmHg, p < 0.001). EPP and REBOA are effective and improve hemodynamic status: both are reasonable first steps in a multidisciplinary management. Zone I REBOA may be useful in patients ‘in extremis condition’ with multiple sites of torso hemorrhage, particularly those in extremis.

Secondary Angio-Embolization After Emergent Pelvic Stabilization and Pelvic Packing Is a Safe Option for Patients With Persistent Hemorrhage From Unstable Pelvic Ring Injuries

Introduction: In patients with severe pelvic ring injuries, exsanguination still is the leading cause of death in the early post-injury phase. While mechanical pelvic ring stabilization and pre-peritoneal pelvic packing are mainly addressing venous bleeding, angio-embolization aims to control arterial bleeding. The goal of the present study was to evaluate the rate of postoperative angio-embolization after mechanical pelvic ring injury stabilization and pre-peritoneal pelvic packing. Bleeding sources detected in the angiography and the patient's outcome were investigated.Patients and Methods: Retrospective observational cohort study at a single academic level I trauma center, reviewing all patients with pelvic ring injuries admitted from 01/2010 to 12/2019. Patients with emergent mechanical pelvic ring stabilization (supraacetabular external fixator and/or pelvic C-clamp) and direct pre-peritoneal pelvic packing were further analyzed. Patients that underwent postoperative angio-embolization were compared with those that did not. All postoperative angio-embolizations were evaluated with regards to bleeding sources and type of embolization.Results: During the study period, a total of 39 patients required immediate mechanical pelvic stabilization and direct pre-peritoneal pelvic packing. Of these, 12 patients (30.8%) underwent a postoperative angio-embolization. The following vessels were identified as bleeding sources: superior gluteal artery (n = 6), obturator artery (n = 2), internal pudendal artery (n = 2), unnamed branches of the internal iliac artery (n = 3). A selective embolization was successful in 11 patients; in 1 patient, an unilateral complete occlusion of the internal iliac artery was performed to control the bleeding. Mean time from hospital admission to the surgical procedure was 52.8 ± 14.7 min and the mean time from admission to angio-embolization was 189.1 ± 55.5 min. The in-hospital mortality rate of patients with angio-embolization was 25.0% (n = 3). Of these, 2 patients died due to multiple organ failure and 1 patient due to severe head injury.Conclusion: Secondary angio-embolization after external pelvic fixation and pre-peritoneal pelvic packing was effective in controlling ongoing bleeding. The most frequently detected bleeding vessel was the superior gluteal artery, which is difficult to surgically address, further highlighting the importance of angio-embolization in the management algorithm.
