Clinical Application of Bilateral Proximal Lower Limb Tourniquet in the Emergency Treatment of Limb Fractures with Hemorrhagic Shock

Objective: To analyze the clinical application of bilateral proximal lower limb tourniquet in the emergency treatment of limb fractures with hemorrhagic shock. Methods: A total of 80 patients with limb fractures and hemorrhagic shock who were admitted to our hospital between February 2016 and April 2020 were selected for the study. Patients were divided into two groups according to their order of admission. The control group (40 patients) had a conventional tourniquet applied to the injured limb, while the experimental group (40 patients) had a bilateral proximal lower limb tourniquet applied in addition to the conventional tourniquet on the injured limb. We observed and recorded the 24-hour mortality rate, the incidence of tourniquet shock, the occurrence of postoperative thrombosis, skin, muscle, and nerve damage, and the time required for blood pressure to recover to the lower limit of the normal range. Results: The 24-hour mortality rate in the experimental group was 0.0%, significantly lower than the 12.5% in the control group, with a statistically significant difference (P<0.05). There was no statistically significant difference between the two groups in terms of the incidence of tourniquet shock, postoperative skin, muscle, and nerve damage, or postoperative limb thrombosis (P>0.05). Compared with the control group, the experimental group had a significantly shorter time for blood pressure to recover to the lower limit of the normal range (P<0.05). Conclusion: In the clinical emergency treatment of patients with limb fractures and hemorrhagic shock, using a bilateral proximal lower limb tourniquet significantly reduces the 24-hour mortality rate, promotes faster recovery of blood pressure to the lower limit of the normal range, and does not increase the risk of tourniquet shock or postoperative skin, muscle, nerve damage, or limb thrombosis, making it valuable for clinical application.
