Background

Patient-ventilator asynchrony (PVA) is common in critically ill patients undergoing mechanical ventilation and may adversely affect clinical outcomes. Traditional bedside assessment methods are subjective and intermittent. We developed a real-time digital platform to continuously monitor ventilator waveforms and quantify overall asynchrony burden of severe pneumonia patients.

Methods

The study retrospectively analyzed mechanically ventilated coronavirus disease 2019 (COVID-19 patients admitted to the Department of Critical Care Medicine of Peking Union Medical College Hospital (PUMCH) from December 2022 to August 2023. Ventilator waveforms were continuously collected and processed using the remote ventilate view platform, which automatically identified eight PVA subtypes and calculated the Overall Asynchrony Index (OAI) across the full ventilation course. Respiratory mechanics were also extracted. Primary outcomes included intensive care unit (ICU) mortality and 28-day ventilator-free days (VFDs), while secondary outcomes included the length of ICU stay and duration of mechanical ventilation. The study used R, Jamovi, and Python for statistical analysis.

Results

Twenty-three mechanically ventilated COVID-19 patients admitted to the ICU at Peking Union Medical College Hospital were included in this study. No correlation was found between the index and ventilatory parameters, compliance, and disease severity. Patients with an OAI ≥10 % were more likely to have fewer 28-day VFDs (1.3 days vs. 11.4 days, P = 0.027) and were demonstrated to have a higher ICU mortality (66.7 % vs. 18.2 %, P = 0.036). Among eight types of PVA, flow insufficiency was found to be associated with prognosis (P = 0.012). OAI correlated with the prognosis of COVID-19 patients. Patients with an OAI ≥10 % were more likely to have fewer 28-day VFDs and higher ICU mortality.

Conclusions

A higher OAI and increased flow insufficiency were associated with worse outcomes in COVID-19 patients receiving mechanical ventilation. This study demonstrates the feasibility and clinical potential of a real-time, platform-based approach for automated detection and longitudinal monitoring of PVA.
患者-呼吸机不同步(PVA)在接受机械通气的危重患者中很常见,并可能对临床结果产生不利影响。传统的床边评估方法是主观的和间歇性的。我们开发了一个实时数字平台来连续监测呼吸机波形并量化重症肺炎患者的总体非同步负担。方法回顾性分析2022年12月至2023年8月北京协和医院重症医学科收治的2019冠状病毒病(COVID-19)患者。使用远程通气视图平台连续收集和处理呼吸机波形,自动识别8种PVA亚型并计算整个通气过程中的总体异步指数(OAI)。同时提取呼吸力学。主要结局包括重症监护病房(ICU)死亡率和28天无呼吸机天数(vfd),次要结局包括ICU住院时间和机械通气持续时间。本研究使用R、Jamovi和Python进行统计分析。结果入选北京协和医院重症监护病房机械通气的新冠肺炎患者23例。该指数与通气参数、依从性和疾病严重程度之间没有相关性。OAI≥10%的患者28天vfd更少(1.3天vs. 11.4天,P = 0.027), ICU死亡率更高(66.7% vs. 18.2%, P = 0.036)。在8种PVA类型中,血流不足与预后相关(P = 0.012)。OAI与COVID-19患者预后相关。OAI≥10%的患者更有可能出现较少的28天vfd和较高的ICU死亡率。结论采用机械通气的COVID-19患者OAI升高和血流不全加重与预后较差相关。本研究证明了实时、基于平台的PVA自动检测和纵向监测方法的可行性和临床潜力。

Background

The anatomical configuration of the anterior scalene muscle, inserting between the subclavian vein and artery, creates a space between them. By placing an ultrasound probe in the infraclavicular area, an optimal longitudinal view of both the proximal part of the axillary and the distal part of the subclavian vein and artery can be obtained, while the pleura is out of view. This Seeing Artery and VEin Simultaneously in the long axis (SAVES) method for ultrasound-guided infraclavicular axillary/subclavian vein cannulation offers theoretical advantages because it may avoid iatrogenic pneumothorax and reduce the risk of arterial damage. The objective of the present study was, to our knowledge, for the first time, to determine the safety and efficacy of the SAVES method for ultrasound-guided infraclavicular axillary/subclavian vein cannulation in adult critically ill patients.

Methods

A retrospective study was performed on consecutive adult critically ill patients who underwent ultrasound-guided infraclavicular axillary/subclavian vein cannulation performed by the same physician in a medical/surgical intensive care unit (12 beds) between 20 August 2021 and 20 December 2024. The overall success rate, the first-pass success rate, the access time and number of attempts, the incidence of difficulty with insertion of the guidewire/dilator/catheter, and the mechanical complication rate were analyzed.

Results

A total of 111 adult critically ill patients required 142 ultrasound-guided infraclavicular axillary/subclavian vein punctures using the SAVES method. The overall success rate was 100%, and the first-pass success rate was 75.4%. The access time was 38.5 (interquartile range: 21.5–80.0) s. The proportions of different numbers (1, 2, and 3) of attempted catheterizations were 88.7%, 9.2%, and 2.1%, respectively. The incidence of difficulty with guidewire insertion was 15.5%, while no difficulty with insertion of the dilator or catheter was experienced. No instance of pneumothorax, hemothorax, arterial puncture, brachial plexus injury, or cardiac tamponade was recorded. The incidence of hematoma formation was 2.1%. The occurrence rate of posterior venous wall penetration was 3.5%. The catheter malposition rate was 5.6%.

Conclusions

The SAVES technique may be a safe and effective approach for ultrasound-guided infraclavicular axillary/subclavian vein cannulation. A larger controlled prospective study is warranted to confirm these findings.
前斜角肌的解剖结构插入锁骨下静脉和动脉之间,在它们之间创造了一个空间。通过在锁骨下区域放置超声探头,可以获得腋窝近端和锁骨下静脉和动脉远端最佳的纵向视图,而胸膜则不在视线范围内。超声引导下锁骨下腋窝/锁骨下静脉插管的长轴同时观察动脉和静脉(saved)方法具有理论上的优势,因为它可以避免医源性气胸并降低动脉损伤的风险。据我们所知,本研究的目的是首次确定超声引导下成人重症患者锁骨下腋窝/锁骨下静脉插管的安全性和有效性。方法回顾性研究2021年8月20日至2024年12月20日在某内科/外科重症监护病房(12张床位)由同一医师连续行超声引导下锁骨下腋窝/锁骨下静脉插管的成年危重患者。分析总成功率、一次通过率、入路时间及次数、导丝/扩张器/导管插入困难发生率及机械并发症发生率。结果111例成人危重患者采用超声引导下锁骨下腋窝/锁骨下静脉穿刺142次。整体成功率100%,一次通过成功率75.4%。获取时间为38.5秒(四分位间距为21.5 ~ 80.0秒),不同次数(1、2、3次)尝试置管的比例分别为88.7%、9.2%、2.1%。导丝插入困难的发生率为15.5%,而扩张器或导管的插入没有困难。无气胸、血胸、动脉穿刺、臂丛损伤或心包填塞病例记录。血肿发生率为2.1%。后静脉壁穿透率为3.5%。导管错位率为5.6%。结论超声引导下锁骨下腋窝/锁骨下静脉置管是一种安全有效的方法。有必要进行更大规模的对照前瞻性研究来证实这些发现。

Background

The potential role of aerosol drug therapy (ADT) in patients with acute respiratory distress syndrome (ARDS) remains uncertain. The objective of this study is to determine the prevalence and practice patterns of ADT in patients with ARDS.

Methods

This secondary analysis of a prospective observational multi-centric cohort study done in critically ill patients to know the ADT practice pattern was conducted in nine participating intensive care units (ICUs) across India between November 2022 and March 2023. The study recruited newly admitted adult patients (age >18 years) who had an artificial airway and required mechanical ventilation (invasive or non‑invasive). These patients were followed up for the next 14 days or until ICU discharge or death. This secondary analysis collected data about screened patients with ARDS, related to each aerosol therapy including ongoing respiratory support, type of drug, and aerosol‑generating device, including ongoing respiratory support, type of drug, and aerosol‑generating device.

Results

Fifty-three (24.3%) of the 218 patients had ARDS, with a mean age of (60.2±14.8) years. At admission, the acute physiology and chronic health evaluation (APACHE II) and sequential organ failure assessment (SOFA) score of the recruited patients were 17.4±7.1 and 7.7±4.0, respectively. Respiratory support was provided with invasive mechanical ventilation (IMV) alone, non-invasive ventilation (NIV) alone, or both in 45.3%, 24.5%, and 30.2% of patients, respectively. The mean duration of the ICU stay was (6.4 ± 4.0) days. Of the 53 patients with ARDS, 51 (96.2%) received 1285 aerosol sessions during follow-up for 330 patient days. Of all patients with ARDS who received aerosol therapy, 71.4% were prescribed while on IMV and 25.7% on NIV. A single drug was used in 60.7% of the aerosol sessions used a single drug, and 39.3% were prescribed combination drugs. Shorter-acting bronchodilators were the predominant drugs, with jet nebulizers (55.4%) being the most commonly used aerosol generators. These were followed by ultrasonic (23.1%) and vibrating-mesh nebulizers (21.5 %). During IMV, only in 50.1% of aerosol sessions (460 out of 918) was an aerosol generator placed at the optimum position (15–30 cm away from the Y-junction).

Conclusions

Aerosol therapy is frequently used in ARDS, with bronchodilators being the most common drug. The jet nebulizer is the most familiar aerosol-generating device, but only half of the aerosol sessions are at the optimum position during invasive mechanical ventilation.
背景:气溶胶药物治疗(ADT)在急性呼吸窘迫综合征(ARDS)患者中的潜在作用尚不确定。本研究的目的是确定急性呼吸窘迫综合征患者ADT的患病率和实践模式。方法对2022年11月至2023年3月期间在印度9个重症监护病房(icu)对危重患者进行的前瞻性观察性多中心队列研究进行二次分析,以了解ADT实践模式。该研究招募了新入院的成年患者(年龄18岁),他们使用人工气道并需要机械通气(有创或无创)。随访14天或至ICU出院或死亡。该二次分析收集了筛选的ARDS患者的数据,这些数据与每种气溶胶治疗相关,包括持续的呼吸支持、药物类型和气溶胶产生装置,包括持续的呼吸支持、药物类型和气溶胶产生装置。结果218例ARDS患者中53例(24.3%)发生ARDS,平均年龄(60.2±14.8)岁。入院时,患者的急性生理和慢性健康评估(APACHE II)评分为17.4±7.1分,序事性器官衰竭评估(SOFA)评分为7.7±4.0分。分别有45.3%、24.5%和30.2%的患者采用有创机械通气(IMV)、无创通气(NIV)或两者同时提供呼吸支持。ICU平均住院时间为(6.4±4.0)d。在53例ARDS患者中,51例(96.2%)在随访期间接受了1285次气溶胶治疗,随访时间为330个患者日。在所有接受气雾剂治疗的急性呼吸窘迫综合征患者中,71.4%的患者同时服用IMV, 25.7%的患者同时服用NIV。在使用单一药物的气雾剂疗程中,使用单一药物的占60.7%,使用联合药物的占39.3%。短效支气管扩张剂是主要药物,喷射雾化器是最常用的气溶胶发生器(55.4%)。其次是超声波雾化器(23.1%)和振动网雾化器(21.5%)。在IMV过程中,只有50.1%的气溶胶试验(918次试验中的460次)将气溶胶发生器放置在最佳位置(距离y型交界处15-30厘米)。结论雾化治疗是ARDS常用的治疗方法,支气管扩张剂是最常用的药物。喷射喷雾器是最常见的气溶胶产生装置,但在有创机械通气过程中,只有一半的气溶胶处于最佳位置。

Background

This study sought to evaluate the role of videoart in decreasing the risk of stress symptoms in patients hospitalized in the intensive care unit (ICU).

Methods

This is a prospective observational cohort study conducted in a general ICU in which 8 of 18 rooms are equipped with a videoart system. Competent patients who spent at least 48 h in the ICU were asked to complete an Impact of Events Scale (IES) questionnaire during hospitalization and at least 1 year after discharge. Patients were recruited from April 2017 until June 2020, and follow-up phone calls were made from June to August 2021. The primary outcome was an IES score indicative of significant stress symptoms during hospitalization. Secondary outcomes were IES scores indicative of significant stress symptoms after discharge and clinical parameters during hospital stay. The cut-off value for high-risk stress symptoms was 26. However, because there is uncertainty in the literature regarding the desired cut-off value, two other values were also analyzed. Outcomes that were found statistically significant were further examined using a logistic regression model for the control of confounders.

Results

Eighty-one patients completed the questionnaire during hospital stay and 24 patients after discharge. At home, patients who were exposed to videoart had a marginally lower mean IES score (median=6 [interquartile range: 0–18] vs. median=32 [interquartile range:10–45], P = 0.054) and a significantly lower rate of high-risk stress symptoms using the primary cut-off value (11.8 % vs. 57.1 %, P=0.038; odds ratio=10.00 95 % CI: 1.22 to 81.80, P=0.03). However, statistical significance was lost after adjustment for confounders (odds ratio=12.00, 95 % CI: 0.67 to 222.00, P=0.09) . There was no difference in the mean IES score, significant stress symptoms rate, or in any of the other endpoints examined during the hospital stay.

Conclusions

There is a trend toward the beneficial effect of videoart for the alleviation of stress symptoms among ICU patients. However, further study is needed to examine the role of this technology.
背景:本研究旨在评估视频治疗在降低重症监护病房(ICU)住院患者压力症状风险中的作用。方法:这是一项在普通ICU进行的前瞻性观察队列研究,其中18个房间中有8个配备了视频艺术系统。在ICU住院至少48小时的合格患者被要求在住院期间和出院后至少1年完成事件影响量表(IES)问卷调查。2017年4月至2020年6月招募患者,2021年6月至8月进行随访电话随访。主要结局是住院期间显著应激症状的IES评分。次要结局是显示出院后显著应激症状的IES评分和住院期间的临床参数。高危应激症状的临界值为26。然而,由于文献中关于期望的截止值存在不确定性,因此还分析了另外两个值。发现有统计学意义的结果进一步使用控制混杂因素的逻辑回归模型进行检查。结果81例患者住院期间完成问卷调查,24例出院后完成问卷调查。在家中,接触视频艺术的患者平均IES评分略低(中位数=6[四分位数范围:0-18]对中位数=32[四分位数范围:10-45],P= 0.054),使用主要临界值,高危应激症状发生率显著降低(11.8 %对57.1 %,P=0.038;比值比=10.00 95 % CI: 1.22至81.80,P=0.03)。然而,校正混杂因素后,没有统计学意义(优势比=12.00,95 % CI: 0.67 ~ 222.00, P=0.09)。在平均IES评分、显著的应激症状率或住院期间检查的任何其他终点方面没有差异。结论视频辅助治疗对缓解ICU患者的应激症状有良好的效果。然而,还需要进一步的研究来检验这项技术的作用。

Background

Inadvertent intensive care unit (ICU) readmission is associated with longer length of stay and increased mortality. Conversely, delayed ICU discharge may represent inefficient use of resources. To better inform discharge timing, several hospitals have implemented machine learning models to predict readmission risk following discharge. However, these models are typically created locally and may not generalize well to other hospitals or patient populations. A single multi-hospital-based model might provide more accurate predictions and insight into features that are applicable across diverse clinical settings.

Methods

This study involved a retrospective multi-center cohort from one academic hospital (Amsterdam University Medical Center [AUMC]) and two large teaching hospitals (Maasstad Ziekenhuis [MSZ] and OLVG). Data from the latter two hospitals were combined to create a pooled model, which was tested on the academic hospital dataset. Data relating to all adult ICU patients were included, starting from the implementation of the electronic health record system until the commencement of model development for each hospital. An XGBoost model was trained to predict a composite outcome of readmission or mortality within 7 days and an autoencoder was used as an out-of-distribution (OOD) detector to capture dataset heterogeneity.

Results

In total, 44,837 patients were available for analysis across the three hospitals. The average readmission rates were 7.1 %, 6.9 %, and 5.9 % for MSZ, OLVG, and AUMC, respectively. Performance evaluation of the local models on AUMC data demonstrated weighted area under the receiver operating characteristic curves of 69.7 %±0.8 %, 70.5 %±0.5 %, and 76.5 %±1.9 %, respectively, whereas the pooled model achieved a weighted area under the receiver operating characteristic curves of 71.1 %±0.7 %. The difference between internal and external performance was reduced when cardiac surgery patients were excluded. The key features across models were albumin levels and the use of oxygen therapy.

Discussion

A single, multi-hospital-based model performed comparably on external datasets, especially when cardiac surgery patients were excluded. However, when applied externally, model predictions risk being uncalibrated for specific patient subgroups and require careful calibration before implementation. While external models were more stable than local ones over OOD scores, their performance was comparable after excluding cardiac surgery patients. Although pooling data marginally improved performance on external datasets, the incorporation of data from diverse hospitals is likely to provide greater benefits.
背景:重症监护病房(ICU)再入院与住院时间延长和死亡率增加有关。相反,延迟ICU出院可能代表资源利用效率低下。为了更好地了解出院时间,几家医院已经实施了机器学习模型来预测出院后的再入院风险。然而,这些模型通常是在当地创建的,可能无法很好地推广到其他医院或患者群体。单一的基于多医院的模型可能提供更准确的预测和对适用于不同临床环境的特征的洞察。方法采用一所学术医院(阿姆斯特丹大学医学中心[AUMC])和两所大型教学医院(Maasstad Ziekenhuis [MSZ]和OLVG)的回顾性多中心队列研究。后两家医院的数据被结合起来创建了一个汇总模型,并在学术医院数据集上进行了测试。从电子健康记录系统的实施开始,直到每家医院的模型开发开始,所有成人ICU患者的数据都被纳入其中。训练XGBoost模型来预测7天内再入院或死亡的综合结果,并使用自动编码器作为分布外(OOD)检测器来捕获数据集异质性。结果三所医院共收集患者44837例。MSZ、OLVG和AUMC的平均再入院率分别为7.1 %、6.9 %和5.9 %。局部模型在AUMC数据上的性能评价显示,受者工作特征曲线下的加权面积分别为69.7 %±0.8 %、70.5 %±0.5 %和76.5 %±1.9 %,而合并模型在受者工作特征曲线下的加权面积为71.1 %±0.7 %。当排除心脏手术患者时,内部和外部表现的差异减小。各模型的关键特征是白蛋白水平和氧治疗的使用。基于单一、多医院的模型在外部数据集上的表现相当,特别是在排除心脏手术患者的情况下。然而,在外部应用时,模型预测有可能无法针对特定患者亚组进行校准,并且在实施之前需要仔细校准。虽然外部模型在OOD评分上比局部模型更稳定,但在排除心脏手术患者后,它们的表现是相当的。虽然汇集数据略微提高了外部数据集的性能,但合并来自不同医院的数据可能会带来更大的好处。

Background

Critically ill patients in ICUs are highly vulnerable to infectious diseases. Early and accurate identification of pathogens is vital for initiating appropriate antimicrobial therapy. To evaluate the diagnostic effectiveness in patients with suspected infectious diseases; three different molecular technologies and conventional microbiological tests were used.

Methods

A total of 97 individuals suspected of having infectious diseases were retrospectively enrolled from July 2023 to January 2024 at Shanghai General Hospital. Samples were collected for metagenomic next-generation sequencing (mNGS), droplet digital polymerase chain reaction (ddPCR), multiplex drop-off digital polymerase chain reaction (MDO-dPCR), and conventional microbiological tests (CMTs) for suspected pathogen detection. The diagnostic efficacies of the three molecular technologies and CMTs were compared, and the effects of their joint application on clinical outcomes were evaluated. Intergroup comparisons were performed using the Kruskal–Wallis test, with a P-value <0.05 considered statistically significant.

Results

Joint detection exhibited a high negative predictive value. The sensitivity of MDO-dPCR, ddPCR, and mNGS was 52.6%, 48.5%, and 96.6%, respectively; and the corresponding specificity was 72.5%, 73.3%, and 50.0%. A positive correlation was observed between pathogen copies detected using MDO-dPCR and procalcitonin (Pearson’s ρ=0.21, P=0.039), acute physiology and chronic health evaluation II (Pearson’s ρ=0.24, P =0.018), and sequential organ failure assessment (Pearson’s ρ=0.25, P=0.012). Therapeutic regimens were adjusted in 51.5% of the patients (50/97) based on the results of the combination tests.

Conclusions

In the present study, we highlighted the significance of molecular technologies for the early diagnosis of patients with suspected infections. These technologies can serve as a complement to CMTs and should be implemented promptly to guide clinicians in providing timely and effective anti-infective treatments.

Background

Improving outcomes among patients with invasive group A Streptococcus pyogenes (iGAS) infections is an unmet clinical need. The main objective of this study was to analyze epidemiological and outcome differences in adults admitted to the intensive care unit (ICU) with iGAS infection over a 15-year period and to evaluate the impact of M1uk isolates and clindamycin optimization on patient outcomes.

Methods

This was a single-center observational study conducted at the ICU of Donostia University Hospital, located in Donostia, Spain. The recruitment of all consecutive adult patients admitted to the ICU by iGAS was carried out from January 2010 to May 2024 and divided into three periods: pre-pandemic (January 2010–2019), pandemic (2020–2021), and post-pandemic (May 2022–2024). The main outcome variables were ICU length of stay, hospital length of stay, and ICU mortality. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software (version 25; SPSS Inc., Chicago, IL, USA). A significance level of P <0.05 was considered for all analyses.

Results

Sixty-eight adults were enrolled, with a crude mortality in pre- and post-pandemic periods being 25.5% and 10.0% (P=0.200), respectively. Twenty (29.4%) were respiratory and 29 (41.2%) were soft tissue infections. The incidence had valleys (<1/100,000) in 2020 and 2021 and peaks (>4/100,000 inhabitants) in 2014, 2019, and 2023. Pre-pandemic patients were significantly younger (median: 58.0 vs. 67.5 years, P <0.050), had lower Charlson scores (median: 0 vs. 2, P=0.009), and required more renal replacement therapy (48.9% vs. 15.0%, P=0.013). Emm1 type was the most frequent isolated strain, with the M1uk lineage being represented in 6 out of 7 Emm1 isolates in post-pandemic period. M1uk-infected patients were older (median: 67.0 vs. 50.0 years, P=0.073) but mortality was similar. Most patients (86.6%) received β-lactams plus clindamycin. Interestingly, time to clindamycin administration was earlier (median: 1 h vs. 24 h; P <0.050) in the post-pandemic period with a 5-fold increase in ICU mortality (5.6% to 26.5%, OR=6.14, 95% CI: 0.74 to 50.85; P=0.090) among those adults who did not receive clindamycin in the emergency department.

Conclusions

The incidence of iGAS infections requiring ICU admission showed no significant increase post-Coronavirus Disease-19 pandemic. The highly toxigenic M1uk strain became predominant, but it was not associated with worse mortality among adult ICU patients.
背景:改善侵袭性A组化脓性链球菌(iGAS)感染患者的预后是一个尚未满足的临床需求。本研究的主要目的是分析15年期间iGAS感染入住重症监护病房(ICU)的成人的流行病学和结局差异,并评估M1uk分离株和克林霉素优化对患者结局的影响。方法本研究是在西班牙多诺斯蒂亚大学医院ICU进行的单中心观察性研究。从2010年1月至2024年5月,通过iGAS连续招募所有ICU成年患者,并将其分为三个时期:大流行前(2010年1月- 2019年)、大流行前(2020年- 2021年)和大流行后(2022年5月- 2024年)。主要结局变量为ICU住院时间、住院时间和ICU死亡率。数据分析使用社会科学统计软件包(SPSS)软件(版本25;SPSS Inc.,芝加哥,伊利诺伊州,美国)。所有分析均考虑P <;0.05的显著性水平。结果纳入68名成人,大流行前和大流行后的粗死亡率分别为25.5%和10.0% (P=0.200)。呼吸道感染20例(29.4%),软组织感染29例(41.2%)。发病率在2020年和2021年出现低谷(1/10万人),在2014年、2019年和2023年出现高峰(4/10万人)。大流行前的患者明显更年轻(中位数:58.0比67.5岁,P <0.050), Charlson评分较低(中位数:0比2,P=0.009),并且需要更多的肾脏替代治疗(48.9%比15.0%,P=0.013)。Emm1型是最常见的分离株,在大流行后时期,7株Emm1分离株中有6株为M1uk谱系。m1uk感染的患者年龄较大(中位数:67.0 vs 50.0岁,P=0.073),但死亡率相似。大多数患者(86.6%)接受β-内酰胺类药物联合克林霉素治疗。有趣的是,大流行后给予克林霉素的时间更早(中位数:1小时对24小时;P <0.050),在急诊科未接受克林霉素治疗的成年人中,ICU死亡率增加了5倍(5.6%至26.5%,OR=6.14, 95% CI: 0.74至50.85;P=0.090)。结论2019冠状病毒病大流行后ICU住院iGAS感染发生率无明显增加。高毒力的M1uk菌株成为优势菌株,但它与ICU成人患者较差的死亡率无关。

Continuous renal replacement therapy (CRRT) is critical in managing several conditions in critically ill pediatric patients. The clinical and economic impact of CRRT is profound and diverse, similar to the patients and conditions it is used to treat. Although much medical literature surrounds CRRT in adults, there remains a gap in research for pediatric populations. This article provides a brief review of current kidney replacement therapies, focusing on CRRT indications, prescribing practices, and modality comparisons. We aim to evaluate the current practical considerations and effectiveness of these therapies and highlight recent advances and future directions, especially in relation to the pediatric patient population. We analyzed recent literature and clinical guidelines on CRRT for critically ill pediatric patients. Key considerations include prescription strategies and comparison of different CRRT modalities, and essential considerations include anticoagulation, settings, and complications. We also explore recent advances in CRRT technologies and their role in clinical management. CRRT offers significant benefits for patients with severe kidney impairments by providing continuous support and improving outcomes. Discussing current recommendations and uses of CRRT and recent advancements will improve its safety and efficacy. Advances in technology and clinical practice are enhancing the use of CRRT, though further research is needed to optimize treatment and address ongoing challenges.
持续肾替代治疗(CRRT)是处理危重儿科患者几种情况的关键。CRRT的临床和经济影响是深刻而多样的,与它用于治疗的患者和疾病相似。尽管很多医学文献都围绕着CRRT在成人中的应用,但对儿科人群的研究仍然存在空白。本文简要回顾了目前的肾脏替代疗法,重点是CRRT的适应症、处方实践和模式比较。我们的目的是评估这些疗法目前的实际考虑和有效性,并强调最近的进展和未来的方向,特别是在儿科患者群体中。我们分析了最近关于儿科危重患者CRRT的文献和临床指南。主要考虑因素包括处方策略和不同CRRT方式的比较,基本考虑因素包括抗凝、设置和并发症。我们还探讨了CRRT技术的最新进展及其在临床管理中的作用。CRRT通过提供持续的支持和改善预后,为严重肾损害患者提供了显著的益处。讨论CRRT目前的建议和使用以及最近的进展将提高其安全性和有效性。技术和临床实践的进步正在加强CRRT的使用,尽管需要进一步的研究来优化治疗和应对持续的挑战。
