目的根据重症监护室(ICU)护理人员对气管插管患者拔管后吞咽功能障碍(PSD)预防知信行(KAP)的调查结果,分析KAP的影响因素。方法以电子调查问卷的方式,采用目的抽样法,选取2022年6-8月江苏、浙江、上海等省市10家医院ICU护理人员作为研究对象,按照问卷条目数乘以5~10倍来计算样本量,抽取医院ICU护理人员对气管插管患者PSD预防KAP问卷调查,ICU护理人员对吞咽功能障碍预防KAP的影响因素,使用单因素、多因素分析方法进行分析。结果共纳入316名ICU护理人员的问卷进行分析,ICU护理人员对于气管插管患者PSD预防知识得分(67.02±11.30)分、态度得分(34.67±6.10)分、行为得分(43.96±8.76)分。不同性别、学历、医院级别的ICU护士、是否专科护士对气管插管患者PSD预防态度维度,差异有统计学意义(P<0.05);不同年龄、职称的ICU护士对气管插管患者PSD预防行为维度,差异有统计学意义(P<0.05)。多重线性回归分析结果显示,学历对ICU护理人员气管插管PSD预防知识、态度产生影响,职称对ICU护理人员行为产生影响(P<0.05)。结论ICU护理人员对气管插管患者PSD预防有一定的知识水平,但认可程度和参与程度有待提升。管理者应重点加强护理人员对气管插管患者PSD预防相关内容培训,明确吞咽功能预防的操作流程,提高重视程度。

为探讨御旱基因型大豆应答干旱胁迫生理和产量的响应机制,以御旱型辽豆14和干旱敏感型辽豆21为试验材料,分析不同生长阶段及抗性品种间的变化规律。2021和2022年连续两年分析水分胁迫对大豆株高、叶面积指数、叶绿素含量、器官生物量、器官含水量、根冠比等生理特性,产量及相关性状的影响。结果表明:随着生育进程的推进,各处理植株的株高、叶面积指数、各器官生物量逐渐累积,整体表现为:鼓粒期>结荚期>开花期>营养生长期。各个时期控水土壤干旱胁迫使植株的叶绿素含量、叶面积指数、株高、各器官含水量降低,但使植株的根冠比提高。相同水分条件下,叶绿素含量整体表现为辽豆21>辽豆14。植株各器官含水量表现为辽豆14>辽豆21。2021年结荚期和鼓粒期控水时,辽豆14的叶面积指数和株高高于辽豆21。同一时期控水,土壤水分提高使大豆根、茎、叶、叶柄、荚皮的干重提高,2020年结荚期和鼓粒期控水时,御旱基因型辽豆14的叶柄干重均显著高于干旱敏感型辽豆21。适宜土壤水分含量条件下两个品种的单株荚数、单株粒数和单株产量较高。各个时期控水,品种差异均显著影响大豆的单株荚数、单株粒数、百粒重和单株产量。同一时期相同水分条件下,大豆的单株荚数、单株粒数和单株产量表现为:辽豆14>辽豆21;而百粒重则表现为:辽豆21>辽豆14。本研究揭示了御旱基因型大豆应答干旱胁迫的生理特征,对指导我国大豆抗旱生产栽培具有重要的理论价值。
