Application and effect of radiation protection nursing measures in PET/CT examination
PET/CT检查中放射防护护理措施的应用与效果

摘要

目的 构建PET/CT检查“分层防护+全程管控”护理体系，评估其对辐射暴露剂量、患者防护认知及护理满意度的影响。方法 选取2025年1月至6月行PET/CT检查的68例患者，随机分为对照组与实验组各34例。对照组实施常规防护护理，实验组采用精准防护护理方案（术前分层评估与分级宣教、术中精准防护干预、术后延续性指导及全程质量控制）。对比两组辐射暴露剂量、防护知识知晓率及护理满意度。结果 实验组甲状腺、胸部、腹部及平均体表辐射剂量均显著低于对照组（P＜0.001），其中平均剂量降低43.75%；实验组防护知识知晓率（97.06%）、护理总满意度（97.06%）均显著高于对照组（70.59%、82.35%），差异均有统计学意义（P＜0.05）。结论 “全流程精准防护护理体系”可有效降低PET/CT检查患者辐射暴露剂量，提升患者防护认知及护理满意度，优化临床放射防护质量，适用于临床推广应用。

Abstract

Objective To construct a nursing system of PET/CT examination with “layered protection+full process control”, and evaluate its impact on radiation exposure dose, patient protection cognition, and nursing satisfaction.
Methods A total of 68 patients who underwent PET/CT examination from January to June 2025 were selected and randomly divided into the control group and the experimental group, with 34 cases in each group. The control group received routine radiation protection nursing, while the experimental group adopted a precise protection nursing plan (preoperative hierarchical assessment and graded health education, intraoperative precise protection intervention, postoperative continuous guidance and full-process quality control). The radiation exposure dose, awareness rate of protective knowledge and nursing satisfaction were compared between the two groups.
Results The radiation doses of thyroid, chest, abdomen and average body surface in the experimental group were significantly lower than those in the control group (P＜0.001), and the average dose was reduced by 43.75%; the awareness rate of protective knowledge (97.06%) and total nursing satisfaction (97.06%) in the experimental group were significantly higher than those in the control group (70.59%, 82.35%), and the differences were statistically significant (P＜0.05).
Conclusion   The "full-process precise protection nursing system" can effectively reduce the radiation exposure dose of patients undergoing PET/CT examination, improve patients' protective cognition and nursing satisfaction, optimize the quality of clinical radiation protection, and is suitable for clinical promotion and application.
