结肠镜检查肠道准备研究热点的可视化分析

背景肠道准备是结肠镜检查前的必要环节,其研究主题较为分散.掌握肠道准备的研究现状及发展趋势,对于疾病研究和实际临床工作具有重要的价值,而目前该领域采用文献计量学的形式对此进行归纳和总结的研究是缺乏的.目的了解结肠镜检查前肠道准备相关研究在国内外的研究热点和发展趋势,以为研究者及临床工作者提供指导价值.方法检索建库至2022-09-10中国知网(CNKI)、万方、维普、中国生物医学文献数据库(CBM)、Web of Science核心数据集中与肠道准备主题相关的文献,采用CiteSpace 6.1.R3软件对年发文量、国家、机构、发文作者、关键词及聚类、文献共被引情况进行可视化分析.结果共分别纳入中、英文文献2340篇、2674篇,年发文量均呈逐年上升趋势,国际上最高产作者为Hassan Cesare,最高产国家为美国、韩国、英国等,国内最高产作者为孟小芬、张媛媛、钮美娥,最高产机构为苏州大学第一附属医院、中国人民解放军总医院、西安交通大学附属第二医院,研究热点为肠道准备质量、肠道准备方案的研究、特殊人群的肠道准备.结论国内外肠道准备相关的研究具备一定研究基础,国内研究能紧跟国际研究热点,但国际间、团队间合作仍需加强,未来应扩大基于更广泛人群的、更契合大数据时代发展的肠道准备相关研究产出,以为临床提供更高质量的研究证据.

Application of early enteral nutrition nursing based on enhanced recovery after surgery theory in patients with digestive surgery

BACKGROUND Postoperative nursing can improve the restlessness and gastrointestinal function of patients with tracheal intubation under general anesthesia in digestive surgery.Wide application of various nursing methods and routine nursing in periop-erative nursing of patients with general anesthesia in digestive surgery.AIM To investigate the impact of early postoperative enteral nutrition nursing based on the enhanced recovery after surgery(ERAS)theory on postoperative agitation and gastrointestinal recovery in patients undergoing general anesthesia that experienced tracheal intubation.METHODS The data of 126 patients with digestive surgery from May 2019 to February 2022 were retrospectively analyzed.According to different nursing methods,they were divided into control group and observation group,with 63 cases in observation group and 63 cases in control group.The patients in the control group had standard perioperative nursing care,whereas those in the observation group got enteral nourishment as soon as possible after surgery in accordance with ERAS theory.Both the rate and quality of gastrointestinal function recovery were compared between the two groups after treatment ended.Postoperative anes-thesia-related adverse events were tallied,patients'nutritional statuses were monitored,and the Riker sedation and agitation score(SAS)was used to measure the incidence of agitation.RESULTS When compared to the control group,the awake duration,spontaneous breathing recovery time,extubation time and postoperative eye-opening time were all considerably shorter(P<0.05).There was no significant difference in the recovery time of orientation force between the two groups(P>0.05);however,the observation group had a lower SAS score than the control group(P<0.05).The recovery time for normal intestinal sounds,the time it took to have the first postoperative exhaust,the time it took to have the first postoperative defecation,and the time it took to have the first postoperative half-fluid feeding were all faster in the observation group than in the control group(P<0.05);Fasting blood glucose was lower in the observation group compared to the control group(P<0.05),while the albumin and hemoglobin levels were higher on the first and third postoperative days;however,there was no statistically significant difference in the incidence of anesthesia-related adverse reactions between the two groups(P>0.05).CONCLUSION The extremely early postoperative enteral nutrition nursing based on ERAS theory can reduce the degree of agitation,improve the quality of recovery,promote the recovery of gastrointestinal function,and improve the nutritional status of patients in the recovery period after tracheal intubation under general anesthesia.
