Introduction: To investigate the impact of risk management intervention based on failure mode and effect analysis (FMEA) theory on the prevention of deep vein thrombosis (DVT) in patients after pulmonary nodule surgery.

Materials: Ninety-six patients with pulmonary nodules included in our hospital from January 2020 to December 2021 were selected for the study.

Methods: Ninety-six postoperative patients with pulmonary nodules included in our hospital from January 2020 to December 2021 were selected for the study. The patients were numbered in order of surgery time and divided into control group (48 cases) and observation group (48 cases) according to the random number table method. The patients in the control group were subjected to conventional nursing interventions, while the patients in the observation group were given risk management interventions based on FMEA theory. The failure mode RPN score, pulmonary function index, recovery and incidence of DVT were compared between the two groups.

Results: After the intervention, the RPN values of each failure mode were lower in the observation group than in the control group (P<0.05). The incidence of DVT was lower in the observation group than in the control group (P<0.05). The forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and FEV1/FVC were better in both groups 7 days after surgery than before surgery (P<0.05), and the levels of these pulmonary function indexes were better in the observation group compared with the control group (P<0.05). The time of tracheal tube removal, time of drainage tube removal, postoperative activity time and hospitalization time were shorter in the observation group than in the control group (P<0.05).

Conclusion: By implementing risk management interventions based on FMEA theory in postoperative patients with pulmonary nodules, it can reduce the incidence of DVT, improve patients' pulmonary function, and accelerate the recovery process.
