脓毒症当前仍然是全球范围内重要的医疗卫生问题,其对世界公共卫生及患者安全带来重大威胁。脓毒症是指宿主对感染反应失调引起的危及生命的器官功能障碍, 其发病率和病死率均极高,是临床重症医学中的重大挑战。在脓毒症病情的进展过程中, 可出现组织灌注不足、血流动力学不稳定等变化, 从而导致多器官功能受损,而心脏是常见的被累及的重要靶器官之一, 这种由脓毒症所导致的不同程度的心肌损伤, 被称为“脓毒性心肌病”, 其发生和发展机制复杂多样, 涉及循环心肌抑制因素、心肌自身因素及自主神经失调等多个方面。文章综述了脓毒症患者发生心肌损伤的高危因素, 以期为临床治疗和预防提供参考。
Sepsis currently remains an important global healthcare issue, and a major threat to world public health and patient safety．Sepsis is a life-threatening organ dysfunction caused by dysregulation of the host response to infection, with extremely high morbidity and mortality,which is a major challenge in clinical critical care medicine．During the progression of sepsis, changes such as inadequate tissue perfusion and haemodynamic instability may occur, leading to impairment of multiple organ functions, while the heart is one of the commonly involved vital target organs, and the varying degree of myocardial damage caused by sepsis is known as “septic cardiomyopathy”．The mechanisms of its occurrence and development are complex and diverse, involving circulating myocardial inhibitory factors, myocardial auto-factors, and autonomic dysregulation．In this paper, we review the high-risk factors for myocardial injury in septic patients, providing a reference for clinical treatment and prevention.
目的 统计分析Ⅲ型食管闭锁与食管气管瘘(esophageal atresia and tracheoesophageal fistula,EA-TEF)术后气管食管瘘复发(recurrent tracheoesophageal fistula,RTEF)的高危因素,并计算高危因素预测RTEF的能力。方法 回顾分析2015年9月—2021年1 月我院EA-TEF患儿的临床资料,并根据术后是否气管食管瘘复发分成复发组(recurrent组,R组)及无复发组(not recurrent组,NR组),比较两组患儿的基本情况、开放手术或胸腔镜手术、手术时间、气管食管瘘结扎方式等术中情况,统计分析RTEF的高危因素,分析其预测RTEF的能力。结果 研究期间共纳入Ⅲ型食管闭锁患儿154例,男98例,女56 例,R组11例,NR组143例,单因素对比分析R组与NR组患儿除吻合口瘘外其余均无统计学差异,其中R组吻合口瘘6人,占该组54.55%;NR组13人,占该组9.10%,P<0.001;Logistic回归模型调整后可见有吻合口瘘相对于无吻合口瘘发生RTEF的风险增加12倍(OR=12.000,95%CI:3.216~44.771)。结论 RTEF与患儿基本情况、术中情况无关,与吻合口瘘显著相关,且有吻合口瘘的患儿出现RTEF风险是无吻合口瘘患儿的12倍。
Objective To statistical analyze the high-risk factors of recurrent tracheoesophageal fistula (RTEF) after the repair of type Ⅲ esophageal atresia and tracheoesophageal fistula (EA-TEF),and evaluate the ability of these high-risk factors predicting RTEF. Methods Retrospectively analyzed the clinical data of children with type Ⅲ EA-TEF in our hospital from September 2015 to January 2021. Patients were divided into two groups (recurrent and non-recurrent group,R and NR group) according to whether there was RTEF. The general situation of those patients, situation during surgery like open or thoracoscopic surgery,operation time,method of tracheoesophageal fistula ligation were compared. Those factors of two groups were analyzed, the high-risk factors of RTEF were summarized, and Logistic regression analysis on the high-risk factors was performed to analyze the ability of predicting RTEF. Results A total of 154 infants with type Ⅲ EA-TEF were included in the study, 98 males, 56 females. There were 11 cases in R group, 143 cases in NR group. Univariate comparative analysis was carried out on R group and NR group, and no statistical differences were found except in anastomotic fistula. There were 6 patients in R group with anastomotic fistula, accounting for 54.55%, and 13 patients in NR group, accounting for 9.10%,P< 0.001. After adjusting the Logistic regression model with the high-risk factors, there was 12-fold increase in the risk of RTEF with anastomotic fistula (OR=12.000, 95%CI: 3.216~44.771) compared with no anastomotic fistula. Conclusion RTEF was not related to patients' general situation or surgery situation, but significantly related to anastomotic fistula. Patients who with anastomotic fistula had a 12-fold increase in the risk of RTEF compared with no anastomotic fistula.
目的 通过对广东地区流行季节的发热新生儿肠道病毒感染临床特点及高危因素探讨,对高危患儿采取有效防治措施。方法 以2019年5月—10月广东省妇幼保健院门诊因发热收治入院的诊断为肠道病毒感染28例新生儿为研究对象,回顾性分析这些患儿的临床资料,分析新生儿肠道病毒感染的高危因素。结果 因发热收治入院的新生儿检测后肠道病毒感染发病率达38.3%,热峰高于38.5℃,发热持续时间大于3 d、细菌培养阴性是新生儿肠道病毒感染的高危因素。结论 在肠道病毒流行季节,对发热新生儿均应常规进行肠道病毒检测,肠道病毒感染患儿,经过有效的治疗后,能够取得较好的治疗效果,但需及时控制病毒的传播途径,针对相关危险因素进行有效的控制,从而降低发病率。
目的 探讨<34周早产儿发生晚发型败血症的危险因素及其病原分布,为防控及治疗用药提供依据。方法 选择2015年1月—2017年12月本院收治的<34周早产儿,根据是否发生晚发型败血症分为感染组及对照组,回顾性分析两组临床资料,对其可能的危险因素采用多因素Logistic回归分析。分析感染组患儿所感染的病原菌及其药敏情况。结果 感染组27例,对照组73例,单因素分析显示感染组患儿出生体重低于对照组,出生窒息、机械通气、使用H2受体阻滞剂、多种抗生素使用、经外周中心静脉置管（PICC）及PICC留置≥14天比例均高于对照组,差异有统计学意义（P<0.05）。多因素logistic回归分析显示出生体质量、PICC留置是<34周早产儿发生晚发型败血症的独立危险因素。感染组中血培养阳性20例,真菌培养阳性11例（55.0%）,G+菌5例（25.0%）,G-菌4例（20.0%）。药敏结果中两性霉素B和氟康唑敏感性高。结论 早期早产儿发生晚发型败血症受多重因素影响,真菌已成为主要致病菌,应针对高危因素加强感染防控,根据血培养及药敏结果合理使用抗菌药物。
