目的 调查住院老年患者因经外周静脉置入中心静脉导管（PICC）而引发的血栓情况，并分析其影响因素，为老年患者置入PICC产生的相关性血栓（PICC-CRT）和症状性血栓的评估与干预提供借鉴。方法 在2023年1月—2023年12月期间，选取广州市第一人民医院接受PICC置管的317例住院老年患者。采用包括患者一般情况调查表、运动功能评定、肌力检测、 Barthel指数评定、Padua评分等多种工具进行综合评估。采用多因素 Logistic 回归构建 PICC-CRT 及症状性血栓的预测模型，并应用逐步回归法优化变量筛选过程。模型性能通过 ROC 曲线进行评估。结果 去除临床资料不完整的患者40例，最终纳入277例患者的完整资料，其中123例患者出现了PICC-CRT，发生率为44.40%（123/277）。血栓分级中，I级78例，Ⅱ级37例，Ⅲ级8例。无症状血栓83例，占67.48%，发生率29.96%（83/277）；症状性血栓40例，占32.52 %，发生率14.44%（40/277）。单因素分析联合多因素Logistic回归显示，卒中史、凝血酶原时间（PT）、导管留置时间是住院老年患者PICC-CRT的关键因素（P＜0.05），预测模型ROC曲线下面积为0.719；置管史、恶性肿瘤史、导管留置时间、置管后并发症数量是住院老年患者PICC症状性血栓的独立影响因素（P＜0.05），预测模型ROC曲线下面积为0.812。结论 文章总结了PICC-CRT和症状性血栓独特的影响因素，基于关键因素构建了预测模型预测其发生，为护理人员预防PICC-CRT和症状性血栓的发生提供了参考。

   Objective To explore the incidence of thrombosis associated with peripherally inserted central catheter（PICC）placement in hospitalized elderly patients and to analyze its influencing factors，in order to provide a reference for the assessment and prevention of PICC-catheter related thrombosis（PICC-CRT）and symptomatic thrombosis in this population．Methods A total of 317 elderly inpatients who underwent PICC placement at a tertiary hospital in Guangzhou between January and December 2023 were enrolled．Comprehensive assessments were conducted using general patient information forms，motor function evaluation，muscle strength testing，Barthel Index，and Padua score．Multivariate Logistic regression analysis was used to construct predictive models for PICC-CRT and symptomatic thrombosis，with variable selection optimized via stepwise regression．Model performance was evaluated using receiver operating characteristic（ROC）curve analysis．Results After excluding 40 patients with incomplete clinical data，277 cases were included in the final analysis．Among them，123 patients developed PICC-CRT，with an incidence rate of 44.40%（123/277）．Thrombosis was graded as Grade I in 78 cases，Grade II in 37 cases，and Grade III in 8 cases．Asymptomatic thrombosis occurred in 83 cases（29.96%），accounting for 67.48% of PICC-CRT；symptomatic thrombosis occurred in 40 cases（14.44%），accounting for 32.52%．Univariate and multivariate Logistic regression analyses identified history of stroke，prothrombin time（PT），and catheter dwell time as key risk factors for PICC-CRT（P＜0.05），with the area under the curve（AUC）of 0.719．History of catheterization，malignancy，catheter dwell time，and number of post-catheterization complications were independent predictors of symptomatic thrombosis（P＜0.05），with an AUC of 0.812．Conclusions This study identified distinct risk factors for PICC-CRT and symptomatic thrombosis in elderly inpatients．Predictive models based on key variables may provide useful references for clinical staff in preventing the occurrence of PICC-related and symptomatic thrombosis．

Methods A total of 180 elderly patients（all underwent painless gastroscopy）admitted to Xiamen Traditional Chinese Medicine Hospital from October 2021 to October 2022 were selected as the study subjects．They were randomly divided into groups using a random number table method．Among them,90 patients in Group A were given a combination of nalbuphine and ciprofol,while 90 patients in Group B were given a combination of nalbuphine and propofol．Anesthesia related indicators,hemodynamics,and perioperative adverse reactions were compared between the two groups．There was no statistically significant difference in the induction amount,induction time,number of additional times,total additional amount,awakening time,and recovery room stay time between the two groups of patients（t=1.486,0.830,1.157,0.941,0.906,1.403,all P>0.05）．The results of repeated measures analysis of variance showed that there were statistically significant differences among the grouping factors,including SBP（F=30.019,P<0.001）,HR（F=282.057,P<0.001）,SpO₂（F=64.518,P<0.001）,time factors SBP（F=21.780,P<0.001）,HR（F=345．118,P<0.001）,SpO₂（F=41.762,P<0.001）,and interaction factors SBP（F=12.941,P<0.001）,HR（F=193.295,P<0.001）,and SpO₂（F=13.546,P<0.001）．The line chart visually shows that the SBP,HR,SpO₂ of Group A patients were lower than those of Group B．The incidence of perioperative adverse reactions in Group A patients（20.00%）was lower than that in Group B patients（56.67%）（χ²=25.593,P<0.001）. Conclusions The two anesthesia regimens used for elderly painless gastroscopy have similar anesthesia effects,with more stable hemodynamics of ciprofol combined with nalbuphine,and a lower incidence of perioperative adverse reactions．

目的 了解门诊老年患者补充与替代医学（CAM）使用现状及影响因素。方法 采用便利抽样法,选取2020年11月—2021年2月广东省某三甲医院老年科门诊就诊的老年患者作为研究对象,调查方法采用一般资料调查表和CAM使用情况调查表进行横断面调查。应用二元Logistics回归分析探讨门诊老年患者使用CAM的影响因素。结果 参与调查的123例老年患者中,有75例（61.0%）老年患者使用CAM,使用CAM的项目主要为中草药、药膳等中国传统医学项目。支付方式是门诊老年患者是否使用CAM的影响因素,使用医保支付的患者较公费、自费患者更愿意使用CAM（OR=5.054,95%CI：1.452~17.590,P<0.05）。结论 CAM在门诊应用广泛,我们应充分发挥我国传统医学优势,为老年人疾病防治提供更多的思路。政府层面也可进一步提高医保覆盖范围,让更多的患者有经济能力可以接受安全、有效的治疗。

Objective To explore the preventing and nursing measures of common complications in elderly patients with ultrasound-guided peripherally inserted central catheter (PICC). Methods The data of 116 elderly patients with PICC catheterization in our hospital from December 2019 to January 2021 were retrospectively analyzed.Patients were divided into implementation group and control group (58 cases each) according to whether they received special preventive nursing for complications of ultrasound-guided PICC catheterization (specialized nursing). The catheterization outcomes and complications of the two groups were compared, the changes in the psychological state were evaluated, and satisfaction rate of the patients was investigated. Results The success rate of the first catheterization, the head-end in place, and ideal placement of the head-end in implementation group were higher than those of the control group, the average number of catheterization and operation time were less than those of the control group, and the differences were statistically significant (P<0.05). The total incidence of various complications in the implementation group was 18.97%, while that in the control group was 46.55%, the difference between two groups was statistically significant (P<0.05). The scores of Self-Rating Anxiety Scale and Self-Rating Depression Scale of the two groups after PICC catheterization were lower than those before catheterization, and the implementation group was lower than the control group, the differences were statistically significant (P<0.05). The total satisfaction rate of patients in the implementation group was 96.55%, and that in the control group was 77.59%, which difference was statistically significant (P<0.05). Conclusion Special preventive nursing measures could improve the catheterization accuracy of ultrasound-guided PICC for elderly patients, reduce the risk of catheter-related complications, relieve the psychological pressure of patients, and improve patients’ satisfaction.
