ICU患者发生产ESBLs革兰阴性杆菌 感染的危险因素分析及预测模型的建立

[摘要]　目的　探讨ICU患者发生产超广谱β-内酰胺酶（extended spectrum beta-lactamases, ESBLs）革兰阴性杆菌感染的危险因素，并构建相关预测模型。方法　选取2017年5月—2021年4月我院ICU发生大肠埃希菌或肺炎克雷伯菌感染的189例患者作为研究对象，收集患者的临床资料，使用单因素分析、LASSO回归和多因素Logistic回归分析ICU患者30 d内发生产ESBLs革兰阴性杆菌感染的危险因素，并据此建立列线图预测模型。结果　急性生理与慢性健康评分≥16分、留置尿管时长≥7 d、抑酸剂使用时长≥3 d、第三代头孢菌素使用时长≥3 d、抗菌药物联用时长≥3 d和ICU住院时间≥15 d是ICU患者30 d内发生产ESBLs革兰阴性杆菌感染的危险因素（P均＜0.05）。依此建立预测ICU患者30 d内发生产ESBLs革兰阴性杆菌感染的列线图风险模型，模型验证结果显示C-index为0.795，校正曲线趋近于理想曲线，AUC为0.807（95%CI：0.775～0.839），在2%～81%预测范围内，列线图净获益。结论　ICU患者30 d内发生产ESBLs革兰阴性杆菌感染的危险因素包括APACHEⅡ评分≥16分、留置尿管时长≥7 d、抑酸剂使用时长≥3 d、第三代头孢菌素使用时长≥3 d、抗菌药物联用时长≥3 d和ICU住院时间≥15 d，据此构建的列线图模型能有效预测ICU患者30 d内发生产ESBLs革兰阴性杆菌感染的风险概率，具有一定的临床价值。     

居家个性化护理,助脑梗死患者早日康复

脑梗死也叫作缺血性脑卒中,是中老年人群中常见的一种脑血管疾病,死亡率、致残率均较高。脑梗死急性期须治疗1~2周,出院后也须长期服药预防复发,从康复角度来讲,也须进行3~6个月的康复治疗。许多老年患者在治疗的过程中会产生恐惧、焦虑等情绪,对治疗配合度、治疗效果均有着一定的影响。因此,脑梗死护理在治疗过程中起着非常重要的作用,患者需要接受个性化的身心护理来配合治疗。     

《医疗质量管理办法》中医疗质量概念及相关问题探讨

采用文献复习和实证研究经验的方法对《医疗质量管理办法》中涉及的医疗质量概念及相关问题进行探讨。《医疗质量管理办法》中的医疗质量的定义存在重大缺失,没有涉及医疗服务的结果,特别是患者安全。医疗质量的定义应与国际相关权威机构保持一致,应高度重视医疗服务的结果,特别是患者安全。

经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.     

康复新液联合碳酸氢钠治疗呼吸重症儿童口腔念珠菌感染的临床疗效

目的 探究康复新液联合碳酸氢钠对呼吸重症儿童口腔念珠菌感染的临床疗效。方法 选取2017年1月-2020年7月在滨州医学院附属医院儿童呼吸重症科进行治疗的呼吸重症儿童口腔念珠菌感染患儿596例为研究对象，根据随机数字表法分为对照组298例和研究组298例，对照组采用碳酸氢钠治疗，研究组采用康复新液联合碳酸氢钠治疗。治疗2周后，分析两组患儿口腔白斑面积、pH值变化、真菌菌落数及治疗有效率，同时记录口腔疼痛评分变化和不良反应发生率。结果 经过两种方案治疗后，两组患儿的白斑面积、pH及真菌菌落数均有改善(P<0.05),口腔疼痛评分均降低(P<0.05),研究组改善情况优于对照组(P<0.05)。治疗2周后，研究组治愈率52.35%高于对照组，总有效率84.56%高于对照组(P<0.05),且两组患儿不良反应发生率均较小，比较无统计学差异。结论 康复新液联合碳酸氢钠对呼吸重症儿童口腔念珠菌感染具有良好的临床疗效，药物的联合应用能够显著降低口腔内白斑面积，改善口腔环境，且安全性较高，值得推广使用。
