Effect of hydration therapy and nursing intervention on preventing contrast-induced nephropathy after interventional treatment of lower extremity arteriosclerosis obliterans.

BACKGROUND: Endoluminal interventions have become one of the main options for the treatment of arteriosclerosis obliterans (ASO). OBJECTIVE: To explore the effect of hydration therapy and nursing intervention on the prevention of contrast-induced nephropathy (CIN) after interventional treatment of lower extremity ASO. METHODS: A convenience sampling method was used to select 94 patients who received ASO treatment in our hospital from March 2019 to May 2021 as the study subjects. All patients underwent endovascular interventional therapy and were randomly divided into two groups by the random number table method, with odd numbers entering the observation group (n= 47) and even numbers entering the control group (n= 47). The control group received routine nursing intervention, while the observation group underwent hydration therapy and had a corresponding nursing intervention scheme. The clinical efficacy of the two groups and the incidence of contrast-induced nephropathy after interventional therapy were compared, and an evaluation of satisfaction within the two groups was performed via a questionnaire. RESULTS: The total effective rate of patients in the observation group was higher after hydration treatment (97.87% vs 87.23%, p< 0.05). The blood urea nitrogen, creatinine, and ß2 microglobulin levels in the observation group were significantly lower than those in the control group after the intervention (p< 0.05). Patients in the observation group had higher nursing satisfaction after using preventive measures of hydration therapy combined with nursing interventions (100% vs 89.36%, p< 0.05). CONCLUSION: Hydration therapy and nursing intervention can effectively prevent CIN after interventional treatment of lower extremity ASO. After interventional therapy, patients had better clinical outcomes, lower biochemical indexes and improved satisfaction evaluations. The therapy is worthy of clinical promotion and application.
