《Respiratory investigation》2021,59(5):628-634
BackgroundThe respiratory dynamics of coronavirus disease 2019 (COVID-19) patients under invasive ventilation are still not well known. In this prospective cohort, we aimed to assess the characteristics of the respiratory system in COVID-19 patients under invasive mechanical ventilation and evaluate their relationship with mortality.MethodsFifty-eight COVID-19 patients who underwent invasive mechanical ventilation between March 11, 2020 and September 1, 2020 were enrolled for the present study. Demographics and laboratory values at baseline were recorded. Respiratory variables such as tidal volume, plateau pressure, positive end expiratory pressure, static compliance, and driving pressure were recorded daily under passive conditions. Further, the median values were analyzed.ResultsMedian age of the patients was 64 years (58–72). Mortality was 60% on day 28. Plateau pressure, driving pressure, and static compliance significantly differ between the survivors and non-survivors. When patients were categorized into two groups based on the median driving pressure (Pdrive) of ≤15 cmH2O or >15 cmH2O during their invasive mechanical ventilation period, there was significantly better survival on day 28 in patients having a Pdrive ≤ 15 cmH2O [28 days (95% CI = 19–28) vs 16 days (95% CI = 6–25), (log-rank p = 0.026).ConclusionCOVID-19 related acute respiratory distress syndrome (ARDS) seemed to have similar characteristics as other forms of ARDS. Lung protective ventilation with low plateau and driving pressures might be related to lower mortality. 相似文献

【摘要】 目的 探讨高原藏族慢性阻塞性肺疾病(COPD)患者合并症的临床分布特点,为高原藏族COPD合并症的预防提供参考。方法 以2012年3月~2016年4月临床确诊的565例伴有合并症的高原藏族COPD患者作为研究对象,回顾性分析高原藏族COPD合并症的患病率、危险因素及发病机制。结果 高原藏族COPD患者的合并症类型主要包括CVD(心血管疾病)、代谢综合征、支气管扩张、感染、焦虑抑郁及支气管哮喘,以合并高血压比例最高为(333%),其次为CVD(包括肺心病及冠状动脉粥样硬化性心脏病、心律失常所致)为165%,糖尿病118%及代谢紊乱合并症97%,支气管扩张症63%。随着增龄,在不同性别中的发病比例无明显差异(P>005), 3个不同年龄段相比,高原藏族COPD合并高血压、CVD在60~80岁年龄段的患病比例最高(P<005),而代谢综合征、支气管扩张和感染的患病比例在>80岁年龄段的患病比例最高,差异有统计学意义(P<005)。结论 在高原缺氧环境下,COPD可与多种疾病伴发,而在COPD低氧、炎症和氧化应激等作用下,进一步促进了CVD、尤其高血压的发生,也可能导致和加重代谢紊乱和糖尿病。因而,重视和研究这些疾病的相关机制对预防高原COPD合并症的发生、进展有重要的临床意义。 相似文献

PurposeHigh explosives are used to produce blast waves to study their biological effects. The lungs are considered as the critical target organ in blast-effect studies. The degree of lung hemorrhaging is related to both the explosive power and the increased lung weight. We studied the characteristics of the biological effects from an air explosion of a thermobaric bomb in a high-altitude environment and the lethality and lung injury severity of goats in different orientations and distances.MethodsGoats were placed at 2.5, 3, 4, and 5 m from the explosion center and exposed them to an air blast at an altitude of 4700-meter. A group of them standing oriented to the right side and the other group seated facing the explosion center vertically. The lung injuries were quantified according to the percentage of surface area contused, and using the pathologic severity scale of lung blast injury (PSSLBI) to score the 4 injury categories (slight, moderate, serious and severe) as 1, 2, 3, and 4, respectively. The lung coefficient (lung weight [g]/body weight [kg]) was the indicator of pulmonary edema and was related to lung injury severity. Blast overpressure data were collected using blast test devices placed at matching locations to represent loadings to goats. All statistical analyses were performed using SPSS, version 26.0, statistical software (SPSS, Inc., Chicago, IL, USA).ResultsIn total, 127 goats were involved in this study. Right-side-standing goats had a significantly higher mortality rate than those seated vertical-facing (p < 0.05). At the 2.5 m distance, the goat mortality was nearly 100%, whereas at 5 m, all the goats survived. Lung injuries of the right-side-standing goats were 1 – 2 grades more serious than those of seated goats at the same distances, the scores of PSSLBI were significantly higher than the seated vertical-facing goats (p < 0.05). The lung coefficient of the right-side-standing goats were significantly higher than those of seated vertical-facing (p < 0.05). Mortality, PSSLBI, and the lung coefficient results indicated that the right-side-standing goats experienced severer injuries than the seated vertical-facing goats, and the injuries were lessened as the distance increased. The blast overpressure was consistent with these results.ConclusionThe main killing factors of the thermobaric bomb in the high-altitude environment were blast overpressure, blast wind propulsions and burn. The orientation and distances of the goats significantly affected the blast injury severity. These results may provide a research basis for diagnosing, treating and protecting against injuries from thermobaric explosions. 相似文献

目的 探讨助听器干预对久居(超过40年)西藏高原地区听障患者的疗效情况。方法 选取49例(63耳)助听器佩戴者进行分析,包括听力情况、听阈、助听器后言语及助听器效果国际问卷主观感受相关分析等,并对助听器补偿效果进行了综合评价。结果 63耳中,中度听力损失34耳,重度听力损失25耳,极重度听力损失4耳。其中单耳35例,问卷平均得分(20.34±4.39)分;双耳14例,问卷平均得分(27.07±4.16)分;双耳得分高于单耳分数。助听言语分辨率与问卷主观评估呈正相关(r=0.528,P<0.01)。助听阈值显示大多数患耳未得到最佳的听力补偿,但助听器干预前后听力比较具有统计学意义(P<0.05),高频听力补偿更为明显。助听后言语测听显示,助听后言语最大分辨率较助听前高(P<0.05)。结论 高原地区听障者对助听器的使用客观听力参数与主观评价相对一致,助听效果较为显著而且双耳验配较单耳验配更具优势,总体助听效果持肯定态度。 相似文献
