Management of Life-Threatening Hemorrhage from Maxillofacial Firearm Injuries Using Foley Catheter Balloon Tamponade

Pre-hospital management of penetrating neck injuries: derivation of an algorithm through a National Modified Delphi

BACKGROUND

Timely and effective pre-hospital management of penetrating neck injuries (PNI) is critical to improve patient outcomes. Pre-hospital interventions in patients with PNI can be especially challenging due to the anatomical injury site coupled with a resource-limited environment. Nationally, in the United Kingdom, no consensus statement or expert agreed guidance exists on how to best manage PNI in the pre-hospital setting.

METHOD

We conducted a national modified e-Delphi study with subject matter experts (SMEs) from multiple professional specialities with experience in the management of PNI. Pre-identified SMEs were contacted and consented prior to participation allowing for a remotely conducted Delphi using REDCap and Microsoft Teams. In Round 1, statements drawn from the literature base were distributed to all SMEs. Round 2 comprised a facilitated and structured discussion of the statements and then an online survey provided final ratification in Round 3. Of the participating SMEs consensus was set a priori at 70%.

RESULTS

Of the 67 pre-identified SMEs, 28 participated, resulting in a response rate of 42%. From the first two rounds, 19 statements were derived with every statement achieving consensus in Round 3. Subsequently, an algorithm for the pre-hospital management of PNI was developed and agreed with SME consensus.

CONCLUSION

Curation of national consensus statements from SMEs aims to provide principles and guidance for PNI management in a complicated patient group where pre-hospital evidence is lacking. Multi-professional national consensus on the best approach to manage these injuries alongside a novel PNI management algorithm aims to optimise time critical care and by extension improve patient outcomes.

The effectiveness of Foley catheter balloon tamponade versus expanding sponges and hemostatic granules for catastrophic penetrating groin hemorrhage with small skin defect: A comparative study in a live tissue porcine model with evaluation of a concise training program

BACKGROUND

Prompt bleeding control in the prehospital phase is essential to improve survival from catastrophic junctional hemorrhage. This study aimed to compare the effectiveness and practicality of Foley catheter balloon tamponade (FCBT), Celox-A, and XSTAT for the treatment of catastrophic hemorrhage from penetrating groin injuries with a small skin defect in a live-tissue porcine model. In addition, this study aimed to determine whether a training program could train military personnel in application of these advanced bleeding control adjuncts.

METHODS

A standardized wound was created in 18 groins from 9 anesthetized swine. Eighteen military medics participated in the training program and performed a bleeding control procedure after randomization over the swine and test products and after transection of the femoral neurovascular bundle. Primary endpoints were bleeding control, time to bleeding control, rebleeding, blood loss, medic performance, and user product rating.

RESULTS

No significant differences were found in vital signs and laboratory values between the groups. In the Celox-A group, 3/6 groins achieved hemorrhage control. This was 6/6 in the XSTAT and FCBT groups. XSTAT scored best on application time, time to obtain hemorrhage control, hemorrhage control score, and practicality. No significant differences were found between groups for rebleeding, amount of blood loss, and medic performance. Military medics had a significant higher preference for XSTAT over Celox-A. This was not significant for FCBT.

CONCLUSION

All tested products proved effective in obtaining hemorrhage control. XSTAT has the highest effectivity and shortest application time for the treatment of catastrophic bleeding from nonpackable, penetrating junctional groin injuries with a small skin defect, compared with Celox-A and FCBT. XSTAT scored best on practicality. This study shows that our training curriculum can be used to train military medics with limited prior experience in the use of advanced bleeding control techniques for penetrating junctional groin injuries with small skin defect.

Pre-hospital management of penetrating neck injuries: a scoping review of current evidence and guidance

Penetrating injuries to the neck pose a unique challenge to clinicians due to the proximity of multiple significant anatomical structures with little protective soft tissue coverage. Injuries to this area, whilst low in incidence, are potentially devastating. Respiratory, vascular, gastro-oesophageal and neurological structures may all be involved, either in isolation or combination. These injuries are particularly difficult to manage in the resource poor, often austere and/or remote, pre-hospital environment. A systematic scoping review of the literature was conducted to evaluate the current available research pertaining to managing this injury profile, prior to the patient arriving in the emergency department. The available research is discussed in sections based on the commonly used trauma management acronym 'cABCD' (catastrophic haemorrhage, Airway, Breathing, Circulation, Disability) to facilitate a systematic approach and clinical evaluation familiar to clinicians. Based on the available reviewed evidence, we have proposed a management algorithm for this cohort of patients. From this we plan to instigate a Delphi process to develop a consensus statement on the pre-hospital management of this challenging presentation.
