Abstract:
Objective:To determine the effects of preperitoneal balloon (PPB) tamponade with different volumes of fluid on hemodynamically unstable pelvic fracture-associated arterial and venous hemorrhage in a swine model.Methods:A model of open-book pelvic fracture with injuries to external iliac vessels was established in 18 female 12-month old Bama miniature pigs. After the successful establishment of hemodynamically unstable pelvic fracture with vascular injury was confirmed by contrast agent imaging, the animals were randomized into 3 even groups ( n=6): a control group (group C) subjected to PPB tamponade with 0 mL fluid injected, group T1 subjected to PPB tamponade with 500-mL fluid injected, and group T2 subjected to PPB tamponade with 1,000-mL fluid injected. The 3 groups were compared in terms of 60-min survival rate, balloon pressure, peritoneal pressure, bladder pressure, 70-min survival rate, blood loss, and infusion volume. Results:There was no statistically significant difference in the basic hemodynamic or other experimental indicators among the 3 groups before experiment, indicating comparability ( P>0.05). The 60-min survival rate in group T2 was 100.0% (6/6), significantly higher than those in group C and group T1 [0.0% (0/6), 0.0% (0/6)] ( P<0.05). After fluid injection, the balloon pressure and preperitoneal pressure in group T2 were respectively (127.2±4.7) mmHg and (34.5±3.6) mmHg, significantly higher than those in group T1 [(78.7±3.8) mmHg and (13.7±2.8) mmHg] and in group C [0 mmHg and (9.0±1.4) mmHg], and the 2 indicators in group T1 were significantly higher than those in group C (all P<0.05). After fluid injection, there was no statistically significant difference among groups C, T1, and T2 in bladder pressure [(6.7±1.0) mmHg, (5.8±1.9) mmHg, and (6.0±1.1) mmHg] or in bleeding volume [(1,163.0±191.3) mL, (1,212.0±148.4) mL, and (975.0±133.2) mL] (all P≥ 0.05). The infusion volume in group T1 [(1,250.0±225.8) mL] was significantly larger than that in group C [(951.7±177.8) mL] ( P<0.05). No colorectal or bladder injuries were found by the anatomy of the experimental animals in 3 groups. Conclusions:PPB tamponade with 1,000-mL fluid injected in a swine model can efficiently control pelvic fracture-associated arterial and venous hemorrhage, and increase the 60-min survival rate with no colorectal or bladder injuries.
