Abstract
There is lack of studies on the effectiveness of transcutaneous contrast-enhanced ultrasound-guided injections of hemostatic agents for liver. spleen and kidney trauma. We compared treatment by hemostatic agents to surgical treatment in a retrospective interventional human study. The study enrolled a total of 135 subjects from emergency unit of the Chinese People's Liberation Army General Hospital in Beijing. Within the cohort, 62 patients received contrast enhanced ultrasound-guided injection of hemostatic agents and the rest received surgical treatments. The injury severity score was lower in the hemostatic agent treatment group than surgical treatment group (p<0.05), but Glasgow coma scale scores did not reach statistical significance. The patients in the surgical treatment group had significantly higher hospital fees than those in the hemostatic treatment group (p<0.05), although the length of hospitalization did not significantly differ between two groups. Safety outcome variables pre- and post-treatment remained within normal limits in both groups. Hemostatic agents were more cost-effective than surgery to treat patients with liver, spleen and kidney trauma. However, given the limited sample size, subsequent studies drawing upon larger populations from multiple medical centers are necessary for follow-up.
