OBJECTIVE: This study investigated the efficacy of precision nursing combined with intermittent pneumatic compression (IPC) devices in preventing perioperative deep vein thrombosis (DVT) in patients with ovarian cancer.
METHODS: A retrospective analysis was conducted on 136 ovarian cancer surgery patients at Xi\'an People\'s Hospital from February 2019 to April 2023. The patients were divided into two groups: 71 patients received precision nursing with IPC intervention (study group), while the remaining received standard nursing care (control group). Key variables analyzed included operation duration, intraoperative blood loss, postoperative blood transfusion requirements, changes in limb circumference, and variations in coagulation parameters activated partial thromboplastin time (APTT), D-Dimer (D-D), Fibrinogen (FIB), and Prothrombin Time (PT) before and after surgery. The incidence of DVT was recorded in both groups to determine risk factors for deep vein thrombosis.
RESULTS: No significant differences were observed between the groups regarding operation duration, intraoperative blood loss, and postoperative blood transfusion rates (P > 0.05). Post-intervention, significant improvements were noted in the study group, with reduced FIB and D-D levels and increased PT and APTT levels compared to the control group (P < 0.05). Furthermore, the study group exhibited a significantly smaller post-intervention difference in limb circumference and a lower incidence of DVT (P=0.003). Precision nursing combined with IPC, pre-intervention D-D < 498.5, and FIGO stages III+IV were identified as independent factors against DVT development.
CONCLUSIONS: Precision nursing paired with an IPC device significantly reduces the risk of perioperative DVT in ovarian cancer patients compared to conventional care.

OBJECTIVE: To investigate the effect of risk management combined with intraoperative precision care on the efficacy and safety of interventional embolization therapy for elderly patients with cerebral aneurysms.
METHODS: In this prospective randomized controlled study, we included 60 elderly patients with cerebral aneurysm treated with interventional embolization. The patients were randomly divided into an experiment group (n=30) and a control group (n=30). The control group received conventional care during the interventional procedure, while the experiment group received risk management combined with precision care. The outcome of the procedure, time to disappearance of clinical symptoms, length of hospitalization, incidence of complications, neurological function and quality of life before and 3 months after the procedure in both groups were assessed and compared.
RESULTS: Compared with the control group, the experiment group had significantly less intraoperative bleeding, shorter operative time (all P<0.001), shorter time to disappearance of clinical symptoms and shorter hospitalization (all P<0.001), and a lower rate of surgical complications (P<0.05). Three months after the operation, the experiment group had better neurological function and quality of life, with significantly lower mRs scores (modified Rankin scale), NIHSS (National Institute of Health Stroke Scale) and higher SF-36 scores (MOS item short from health survey) than those of the control group (both P<0.001).
CONCLUSIONS: Risk management combined with precision care can effectively improve the surgical safety of interventional embolization in elderly patients with cerebral aneurysm, reduce the incidence of surgical complications, and thus improve the prognosis.
