Objective To investigate the effects of two fluid resuscitation methods on hemodynamics, myocardial injury and prognosis in patients with traumatic hemorrhagic shock (THS). Methods A total of 120 patients with THS admitted to the hospital from February 2018 to February 2023 were selected, and randomly divided into the limited group and the control group, with 60 patients in each group. The control group received conventional fluid resuscitation, while the limited group received limited fluid resuscitation (LFR). The hemodynamic indicators, myocardial damage indicators, and prognosis of the two groups were compared. Results After resuscitation, cardiac output (CO), cardiac index (CI) and mean arterial pressure (MAP) in the limited group were higher than those in the control group (P＜0.05). After resuscitation, the levels of cardiac troponin T (cTnT), creatine kinase (CK) and creatine kinase isozyme (CK-MB) in the limited group were lower than those in the control group (P＜0.05). After resuscitation, the incidence of complications in the limited group was lower than that in the control group (P＜0.05). Conclusion Compared with conventional fluid resuscitation, LFR can significantly improve the patients' hemodynamics, alleviate myocardial damage, and reduce the occurrence of complications
