Objective To investigate the therapeutic efficacy of Huiyang Decoction on traumatic hemorrhagic shock and to propose a new viable treatment approach for the disease.Methods A retrospective analysis was performed on a cohort of 40 patients with traumatic injuries who underwent surgical intervention at the Department of Critical Care Medicine,Wuxi Ninth People's Hospital Affiliated to Soochow University,from March 2022 to December 2023.A total of 20 patients who received standard hemorrhagic shock treatment and received postoperative blood transfusion to hemoglobin 80 g/L were selected as the control group.A total of 20 patients who were treated with Huiyang decoction for 3 days on the basis of the above treatment were selected as the observation group.The improvement of serum creatine kinase(CK)and creatine kinase isoenzyme(CK-MB)in the two groups was observed.The total effective rate was defined as the recovery+significant improvement+improvement of CK and CK-MB to compare the total effective rate after treatment,and TCM symptom score before and after treatment between two groups.Results After 3-day treatment,the CK level in the observation group was higher than that in the control group before treatment(P<0.05),and decreased after treatment,but there was no significant difference compared with the control group(P>0.05).CK-MB levels showed no significant difference between the two groups before treatment(P>0.05),and that in the observation group was lower compared with the control group after treatment(P<0.01).The total effective rate of CK-MB in the observation group was significantly higher than that in the control group(85.00%vs 55.00%,x2=4.290,P<0.05).The observation group slightly surpassed control group in the total effective rate of CK,however,there was no statistically significant difference(50.00%vs 30.00%,x2=1.670,P>0.05).Following treatment,both groups exhibited a significant reduction in TCM syndrome scores for dizziness,fatigue,and cold limbs compared to pre-treatment(P<0.01),and the observation group demonstrated lower TCM syndrome scores compared to the control group(P<0.05).Conclusion Huiyang Decoction has a beneficial effect on traumatic hemorrhagic shock,and can increase TCM symptom scores and improve abnormalities of serum CK-MB level after hemorrhagic shock.
