Effect of nurse-led multiple disciplinary team-based intervention in the prevention of venous thromboembolism in paitents undergoing general surgery

Objective To investigate the effect of nurse-led multiple disciplinary team-based intervention in the prevention of venous thromboembolism in paitents undergoing general surgery. Methods A total of 118 patients who underwent general surgery in the Tianjin First Central Hospital from May 2017 to October 2018 were divided into study group and control group by random digits table method, with 59 cases in each group. The control group received routine thrombosis prevention nursing, the study group carried out nurse-led multiple disciplinary team-based intervention. The condition of lower limbs deep venous hemodynamic was detected by color Doppler ultrasonography at 3 days after surgery, the levels of D-dimer, thrombelastograph coagulation analyzer (TEG) coagulation parameters were also measured at after 24 hours of admission and postoperative day 3, respectively. Results The vein blood stasis rate was 94.9% (3/59) in the study group, 79.7% (12/59) in the control group, the venous blood flow of the lower 1imbs in the study group was better than that in the control group (Z value was 2.477, P<0.05). At 3 days after surgery, the levels of D-dimer were (5.26±1.42) mg/L in the study group, (6.36±1.58) mg/L in the control group, D-dimer was decreased in study group compared to the control group, the difference was statistically significant (t value was 3.991, P<0.05). Coagulation reaction time(R) value and solidification angle(Angel), maximum thrombus intensity(MA), composite coagulation index(CI) levels were (5.30±0.91) min, (69.64±21.93) deg, (65.40±13.76) mm and (1.23±0.20) in the study group, those index were (4.41±0.75) min, (76.64±16.02) deg, (70.98±13.39) mm, (2.09±0.36) in the control group, R value were increased and Angel, MA, CI levels were decreased in the study group compared to the control group (t value was 2.001-15.997, P<0.05). Conclusions Nurse-led multiple disciplinary team-based intervention improves the lower limbs deep venous hemodynamic and coagulation function, as well as reduce the incidence of venous thromboembolism.
