The hemodynamic management of adult patients with distributed shock often includes the use of catecholamines vasoconstrictor drugs. It was unclear whether adding vasopressin or vasopressin analogs to catecholamine therapy was beneficial for the treatment of patients with distributed shock. The Canadian Society of Intensive Care recently updated its clinical practice guideline to provide recommendations for the addition of vasopressin to catecholamine boosters in adults with distributed shock. This paper interprets it to assist domestic doctors for better understanding of the latest progress.
Brain injury after cardiopulmonary resuscitation is closely related to the survival rate and prognosis of neurological function of cardiac arrest (CA) patients. Recently, the American Academy of Neurology (AAN) published a practice guideline which had updated the evaluation of different treatments for reducing brain injury following cardiopulmonary resuscitation. In order to master and transmit AAN 2017 practice guideline on reducing brain injury following cardiopulmonary resuscitation, this paper interprets the new AAN clinical practice guideline to assist Chinese clinicians for better studying the guideline.
ObjectiveTo systematically evaluate the efficacy of fiberoptic bronchoscopy for patients with stroke-associated pneumonia (SAP).MethodsAll randomized controlled trials on fiberoptic bronchoscopy in treating SAP were collected from Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, Chinese Biology Medicine database, Wanfang database, and Chongqing VIP database. Two reviewers screened the literature, extracted data, and assessed the methodological quality of included studies. And then meta-analysis was conducted using RevMan 5.3 software.ResultsTwelve studies with 1 107 patients were included. Compared with the routine therapy, the fiberoptic bronchoscopy combined with routine therapy showed a better efficacy [relative risk (RR)=1.26, 95% confidence interval (CI) (1.17, 1.36), P<0.000 01], and indicated a shorter hospital-stay [mean difference (MD)=–4.29 days, 95%CI (–5.06, –3.52) days, P<0.000 01] and lower Clinical Pulmonary Infection Score values [MD=–1.13, 95%CI (–1.77, –0.49), P=0.000 5]. Meanwhile, a downward trend in the level of procalcitonin [standardized mean difference (SMD)=–3.86, 95%CI (–4.22, –3.50), P<0.000 01], tumor necrosis factor α [SMD=–2.75, 95%CI (–3.84, –1.66), P<0.000 01], and C-reactive protein [SMD=–2.55, 95%CI (–3.83, –1.26), P=0.000 1], as well as a higher level of partial pressure of oxygen in arterial blood [MD=15.34 mm Hg (1 mm Hg=0.133 kPa), 95%CI (6.38, 24.31) mm Hg, P=0.000 8] appeared after the combined treatment.ConclusionBased on the conventional therapy, the treatment of fiberoptic bronchoscopy can improve the efficacy, shorten the hospital stay, relieve the systemic inflammatory responses, and improve the oxygenation of SAP patients.
ObjectivesTo systematically review the efficacy and safety of enteral nutrition (EN) for severe acute pancreatitis (SAP) patients within 48 hours after admission.MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on early EN (starting within 48 hours after admission) in SAP from inception to October, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 9 RCTs involving 1 074 patients were included. The results of meta-analysis showed that: compared to patients with EN after 48 hours or parental nutrition, the patients given EN within 48 hours after admission had lower mortality (RR=0.53, 95%CI 0.29 to 0.96, P=0.036) and morbidity of multiple organ dysfunction syndrome (MODS) (RR=0.58, 95%CI 0.44 to 0.77, P<0.001). However, no significant differences were found in systemic inflammatory response syndrome (SIRS) (RR=1.00, 95%CI 0.86 to 1.16, P=1.00).Conclusions The current evidence shows that EN within 48 hours after admission can reduce the mortality and morbidity of MODS in SAP patients. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
Objective To investigate the effects of high dose ulinastatin with lung protective ventilatory strategies on respiratory function and prognosis in critical disease patients combined with acute lung injury/acute respiratory distress syndrome. Methods Using retrospective analysis, we involved the critical disease patients combined with ALI/ARDS in ICU of The Second Affiliated Hospital of Anhui Medical University. According to whether they were treated with high dose ulinastatin with lung protective ventilatory strategies or not, the patients were divided into the treatment group and the control group. Then pulmonary vascular permeability index (PVPI), extravascular lung water index (EVLWI), oxygenation index, length of SIRS, length of stay in ICU and APACHE Ⅱ score were observed. Statistic analysis was conducted using SPSS 19.0 software. Results A total of 24 patients were included, 13 cases in the treatment group and 11 cases in the control group. After 72 h, PVPI (P=0.016), EVLWI (P=0.045), length of SIRS (P=0.002), length of stay in ICU (P=0.024) and APACHE Ⅱ score (P=0.002) decreased significantly, while oxygenation index (P=0.004) increased significantly in the treatment group compared with the control group. Conclusion High dose ulinastatin with lung protective ventilatory strategies decreased lung capillary permeability, reduced lung blood capillary leakage and extravascular lung water, resulted in the improvement of lung oxygenation function, decreased of length of stay in ICU and the improvement of prognosis in critical disease patients combined with acute lung injury/acute respiratory distress syndrome.
ObjectiveTo systematically review the efficacy and safety of intravascular cooling versus surface cooling for induced mild hypothermia on the prognosis of patients with cardiac arrest (CA) after resuscitation.MethodsPubMed, EMbase, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect cohort studies and randomized controlled trials (RCTs) about the efficacy and safety of intravascular cooling versus surface cooling for CA patients after resuscitation from inception to July 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 13.0 software.ResultsA total of 9 cohort studies and 3 RCTs involving 2 104 patients were included. The results of meta-analysis showed that: the rate of good neurological function was significantly higher (OR=1.45, 95%CI 1.18 to 1.78, P<0.001) and the induction time was significantly shorter (SMD=−1.35, 95%CI −2.34 to −0.36, P=0.008) in the intravascular cooling group, but there was no statistical difference in mortality between two groups (OR=0.84, 95%CI 0.70 to 1.00, P=0.053). In terms of complications related to mild hypothermia, the rate of excessive hypothermia (OR=0.27, 95%CI 0.18 to 0.41, P<0.001) and arrhythmia (OR=0.60, 95%CI 0.40 to 0.89, P=0.012) was significantly lower in the patients treated with intravascular cooling, but the incidence of coagulopathy was higher (OR=1.61, 95%CI 1.05 to 2.49, P=0.03). There was no statistical difference in the incidence of pneumonia between two groups (OR=1.20, 95%CI 0.94 to 1.53, P=0.147).ConclusionCurrent evidence shows that intravascular cooling has significant neurological protection for patients with CA compared with surface cooling since it can decrease the induction time and the rate of excessive hypothermia and arrhythmia, but it may have a negative effect on the coagulation function. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveThe aim of this study was to assess the disease burden of non-COVID-19 lower respiratory infection (LRI) in China during the period 1990−2021, particularly during the period 2019−2021. MethodsData on the burden of disease for LRI in China were obtained from the GBD2021 database. A Joinpoint regression model was used to describe the changes in disease burden trends of LRI in China from 1990 to 2021, and the results are presented in terms of average annual percentage change (AAPC). ResultsIn 2021, the age-standardized incidence rate of LRI in China was 2 853.31/100 000, the age-standardized rate of DALY was 347.67/100 000, and the age-standardized mortality rate was 14.03/100 000. Compared with 1990, the AAPC were: −2.13%, −6.89% and −4.10% respectively. In contrast, during the COVID-19 pandemic, both showed a decreasing and then increasing trend, except for the age-standardized incidence rate, which showed a decreasing trend. Children under 5 years of age have experienced the greatest reduction in the burden of disease over the past decades, while the burden of disease has increased in absolute terms for the elderly over 70 years of age. Compared with 1990, the disease burden of LRI in China due to each pathogenic microorganism has decreased. And during 2019−2021, all pathogens showed an increasing trend, except for ASMR caused by influenza (APC=−55.21%) and respiratory syncytial virus (APC=−53.35%). In 2021, the primary attributable risk factors for LRI mortality in China shifted from household air pollution due to solid fuels, childhood underweight, and childhood stunting in 1990 to ambient particulate matter pollution, smoking, and secondhand smoke. ConclusionThe disease burden of LRIs in China showed an overall decreasing trend from 1990 to 2021, but with large variations between age groups and pathogens. During the two years following the outbreak of the COVID-19 pandemic, the incidence of LRI in China, along with the disease burden caused by influenza and respiratory syncytial virus, significantly declined. Over the past few decades, the attributable risk factors for mortality and DALYs have undergone substantial changes. To address this phenomenon, targeted measures should be implemented to reduce the burden of LRI on the population caused by air pollution and smoking.
