To explore the effect of intraoperative preventive nursing intervention on postoperative complications of lower limb deep vein thrombosis and pressure injury in obese patients with gastroesophageal reflux disease(GERD).

100 obese patients with GERD who underwent laparoscopic gastric volume reduction surgery at the People’s Hospital of Xinjiang Uygur Autonomous Region from January to December 2023 were selected as the research subjects. They were randomly divided into an experimental group and a control group, with 50 cases in each group. The control group received routine nursing intervention, while the experimental group received intraoperative preventive nursing intervention on the basis of the control group. Independent sample t-test was used to compare postoperative D-dimer levels, lower limb deep vein flow velocity, lower limb DVT incidence, DVT diameter, and pressure injury incidence between two groups of patients.

The average level of D-dimer in the experimental group after surgery was lower than that in the control group [(1.14±0.23) mg/L vs (1.23±0.21)mg/L]. The lower limb deep vein velocity in the experimental group after surgery was faster than that in the control group [(22.17±3.26)m/s vs (20.43±1.88)m/s]. The incidence of DVT detected in the experimental group after surgery was lower than that in the control group (2 cases vs 10 cases). The DVT diameter in the experimental group after surgery was smaller than that in the control group [(0.37±0.14)cm vs (0.46±0.09)cm], and the differences were statistically significant (t=2.138, P=0.035; t=-3.269, P=0.001; χ²=3.774, P=0.028; t=4.010, P<0.001). The incidence of pressure injury in the experimental group was lower than that in the control group (2% vs 16%), and the differences were statistically significant (χ²=3.481, P=0.031).

Intraoperative preventive nursing intervention can reduce the incidence of lower limb deep vein thrombosis and pressure injury in obese patients with GERD after surgery, and improve the prognosis of patients.
