BACKGROUND: Pelvic bleeding from trauma and postpartum hemorrhage is often difficult to treat successfully by emergency providers particularly in low resource environments, when hospital presentation is delayed or there is a lack of immediate surgical, anesthesia, and transfusion capabilities. Pneumatic anti-shock garments (PASG) decrease pelvic blood flow and hemorrhage. A tightly fitted neoprene non-pneumatic anti-shock garment (NASG) has been shown to decrease blood loss and improve survival rates from postpartum hemorrhage. AIMS: The objective of this study was to determine whether blood flow to the pelvis is decreased by use of the NASG or by an improvised PASG. METHODS: A PASG was made using three bicycle tubes, placing one tube on each leg and one on the lower abdomen/pelvis, wrapping firmly with sheets and inflating the tubes to approximately 3.5 bar (45 psi). A Doppler ultrasound was used to measure distal aortic blood flow in 12 healthy adults at baseline and in both devices. Data were analyzed with one sample and paired t tests. RESULTS: Mean flow was 1.99 l/min at baseline. Mean flow decrease was 1.11 [95% confidence interval (CI): 0.64-1.57, p = 0.0003 for the difference] for the PASG and 0.65 (95% CI: 0.03-1.26, p = 0.04) for the NASG. The PASG decreased blood flow more than the NASG (mean difference: 0.46, 95% CI: 0.02-0.90, p = 0.04). CONCLUSIONS: Both devices decreased distal aortic blood flow, but the improvised PASG device decreased it by a larger margin. |
