随着人们生活水平的不断提高,饮食习惯不断发生变化,高脂、高盐及高糖饮食越来越普遍,导致产生如慢性肾脏疾病等许多慢性疾病.血液透析为终末期慢性肾脏疾病患者常用的治疗手段之一 [1],临床应用较广泛,可有效降低患者的病死率,提高患者的生命质量.为了提高透析治疗质量,保障治疗安全,从医学工程角度结合血液透析治疗原理分析,最关键的因素在于保证透析液的质量.因此,血液净化中心的质量控制工作应围绕水质监控开展,针对各种异常情况作好预案,落实好持续改进工作,以提高工作质量.
Objective To propose a calibration method for the parameters of uterine contraction pressure probes in fetal monitors.Methods With the reference of calibration methods and indicator requirements for other parameters of existing fetal monitors,the calibration method for the parameters of the uterine contraction pressure probe was designed.Based on this method,the calibration of the parameters of the uterine contraction pressure probe(including nonlinear error,repeatability,and temperature drift)for six fetal monitors from three different manufacturers was carried out,and the uncertainty of the nonlinear error of uterine contraction pressure for this method was analyzed.Results The nonlinear errors of the uterine contraction pressure probes of six fetal monitors at theoretical values of 25%,50%,and 75%were-2.6%to 3.3%,-4.0%to 3.0%,and-4.3%to 3.3%,respectively,which met the index requirements of YY/T 0449-2018"Ultrasonic Doppler Fetal Monitor"(no more than±10%).The repeatability range was 0.5%to 1.0%;The temperature drift range was-1～0 mmHg;The uncertainty range of the non-linear error of uterine contraction pressure was 1.1%to 1.4%.Conclusion The parameters of the uterine contraction pressure probe of the fetal monitor can be effectively evaluated through this method.The uncertainty of its nonlinear error is less than 1/3 of the maximum allowable error(±10%),indicating that it can be used for calibration analysis of clinical instruments.
Objective The effectiveness of three different methods for cleaning luminal instruments used in thoracoscopic surgery was compared,providing a basis for improving the quality of luminal instrument cleaning.Methods With the selection of 568 thoracoscopic surgical instruments used in hospitals from January 2021 to June 2022,the instruments were divided into three groups using the random number table method,which were subjected to mechanical spray cleaning(193 pieces,mechanical group),manual cleaning(171 pieces,manual group),and decompression boiling cleaning(204 pieces,decompression group).The pass rates of three groups of cleaning were compared.Results The cleaning qualification rates of the mechanical group,manual group,and decompression group were 48.20%,81.87%,and 87.75%,respectively,with statistically significant differences(χ2 =95.087,P<0.05).There were statistically significant differences in the cleaning pass rate between the mechanical group and the manual group and the decompression group(χ2=43.207,70.120,P<0.05);There was no statistically significant difference in the cleaning qualification rate between the manual group and the decompression group(χ2 =2.085,P>0.05).Conclusions Mechanical spray cleaning has poor cleaning effect on the lumen instruments used in thoracoscopic surgery,while manual cleaning and decompression boiling cleaning have similar effects.However,due to significant human factors,it is difficult to ensure the effectiveness of manual cleaning.With simple operation,higher work efficiency,fixed cleaning process,and more stable and reliable cleaning effect,decompression boiling cleaning can accelerate the turnover efficiency and use frequency of lumen instruments,while reducing occupational exposure problems caused by manual cleaning.
Objective The effect of comprehensive nursing group in hemodialysis patients with chronic renal failure was explored.Methods 80 patients with chronic renal failure admitted to the First People's Hospital of Fuzhou City from March 2020 to March 2022 were divided into the control group(40 cases,receiving routine nursing intervention)and the observation group(40 cases,receiving comprehensive nursing group intervention),by using the random number table method,with continuous intervention for 4 weeks.The psychological status[assessed by Self-rating Depression Scale(SDS)and Self-rating Anxiety Scale(SAS)],incidence of complications and quality of life[assessed by Quality of Life Rating Scale(QOL)]were compared between the two groups.Results After intervention,the scores of SDS and SAS and the incidence of complications in the observation group were lower than those in the control group,and the QOL scores were higher than those in the control group,with statistical significance(P<0.05).Conclusion The comprehensive nursing team can improve the negative emotions of patients with chronic renal failure treated with hemodialysis,reduce the risk of complications,and improve their quality of life.
目的 探讨腹腔镜子宫切除术治疗子宫内膜癌患者的临床效果.方法 选取2020 年 1 月至 2022 年 1 月医院收治的 40 例子宫内膜癌患者,根据随机数字表法分为对照组和试验组,每组 20 例.对照组行开腹子宫切除术治疗,试验组行腹腔镜子宫切除术治疗.比较两组手术指标、淋巴结清扫数量及治疗前后的排尿功能和膀胱功能,并统计两组术后并发症发生率.结果 试验组术中出血量少于对照组,手术时间、术后肛门排气时间、住院时间均短于对照组,差异均有统计学意义(P<0.05).两组淋巴结清扫数量比较,差异无统计学意义(P>0.05).治疗前,两组排尿功能和膀胱功能比较,差异均无统计学意义(P>0.05);治疗后,试验组排尿功能和膀胱功能各项指标均优于对照组,差异均有统计学意义(P<0.05).试验组术后并发症发生率低于对照组,差异有统计学意义(P<0.05).结论 与开腹手术相比,腹腔镜子宫切除术治疗子宫内膜癌患者的效果更优,可减少术中出血量,加快术后恢复,改善排尿功能和膀胱功能,且安全性更高.
