Il est proposé d'utilser l'administration locale d'hémostatiques pour arrêter les hémorragies notamment jonctionelles. Ceci est en théorie efficace. Néanmoins il s'agit de produits onéreux et des moyens simples comme l'emploi de sond à ballonet est également proposé. Ce travail confirme la pertinence d'une telle démarche, notamment le XStat. Mais il montre aussi qu'une sonde à ballonet est pratiquement aussi efficace. Alors, surtout ne pas se priver.

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.

Background

Tension pneumothorax (TP) is a life-threatening condition. The immediate recommended management is needle decompression (ND), followed by the insertion of an intercostal chest drain. The European Trauma Course (ETC) and the Advanced Trauma Life Support (ATLS) guidelines differ on needle size and decompression site, creating clinical uncertainty. This meta-analysis aims to explore the optimal approach for emergency needle decompression in TP.

Methods

This meta-analysis followed the PRISMA 2020 guidelines. It included English-language RCTs, cohort, case–control, cross-sectional studies, and case series with more than six patients. Studies on adults undergoing needle decompression therapy for TP or with chest wall thickness measurements were included. Ovid MEDLINE, Embase, and Web of Science databases were searched until May 31, 2024. Data were extracted, assessed for quality using OCEBM and GRADE, and analyzed using SPSS and OpenMeta with random-effects models. Primary outcome: needle decompression failure rate. Secondary outcomes: patient demographics, cannula size, and chest wall thickness comparisons.

Results

This review analyzed 51 studies on needle decompression for TP, with a weighted mean patient age of 36.67 years. Radiological data from 24 studies (n = 8046) indicated a 32.84% failure rate for needle penetration into the pleural cavity (I²: 99.72%). Increased needle length reduced failure rates by 7.76% per cm. No significant differences in chest wall thickness between genders were observed (T-test, p = 0.77), but thickness at the 5th anterior axillary line (5AAL) and 5th midaxillary line (5MAL) was less than at the 2nd midclavicular line (2MCL). Injury rates were higher at 5AAL than 5MAL, with strong positive correlations between needle length and injury at these sites (0.88, 0.91).

Conclusion

Based on our meta-analysis, a 7 cm needle may be appropriate for decompression of right-sided tension pneumothorax at either the 5th intercostal space along the midaxillary line or the 2nd intercostal space along the midclavicular line. For left-sided cases, given the potential risk of cardiac injury, the 2nd midclavicular line is a safer option. However, these recommendations should be interpreted with caution due to considerable heterogeneity among the included studies, potential risk of bias, and variability in measurement techniques. Clinical decisions should always be individualized, taking into account patient-specific factors.
