ABSTRACT

OBJECTIVE@#To analyze the predictors of successful weaning off extracorporeal membrane oxygenation (ECMO) after extracorporeal cardiopulmonary resuscitation (ECPR).@*METHODS@#The clinical data of 56 patients with cardiac arrest who underwent ECPR in Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from July 2018 to September 2022 were retrospectively analyzed. According to whether ECMO was successfully weaning off, patients were divided into the successful weaning off group and the failed weaning off group. The basic data, duration of conventional cardiopulmonary resuscitation (CCPR, the time from cardiopulmonary resuscitation to ECMO), duration of ECMO, pulse pressure loss, complications, and the use of distal perfusion tube and intra-aortic balloon pump (IABP) were compared between the two groups. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors for weaning failure of ECMO.@*RESULTS@#Twenty-three patients (41.07%) were successfully weaned from ECMO. Compared with the successful weaning off group, patients in the failed weaning off group were older (years old: 46.7±15.6 vs. 37.8±16.8, P < 0.05), higher incidence of pulse pressure loss and ECMO complications [81.8% (27/33) vs. 21.7% (5/23), 84.8% (28/33) vs. 39.1% (9/23), both P < 0.01], and longer CCPR time (minutes: 72.3±19.5 vs. 54.4±24.6, P < 0.01), shorter duration of ECMO support (hours: 87.3±81.1 vs. 147.7±50.8, P < 0.01), and worse improvement in arterial blood pH and lactic acid (Lac) levels after ECPR support [pH: 7.1±0.1 vs. 7.3±0.1, Lac (mmol/L): 12.6±2.4 vs. 8.9±2.1, both P < 0.01]. There were no significant differences in the utilization rate of distal perfusion tube and IABP between the two groups. Univariate Logistic regression analysis showed that the factors affecting the weaning off ECMO of ECPR patients were pulse pressure loss, ECMO complications, arterial blood pH and Lac after installation [pulse pressure loss: odds ratio (OR) = 3.37, 95% confidence interval (95%CI) was 1.39-8.17, P = 0.007; ECMO complications: OR = 2.88, 95%CI was 1.11-7.45, P = 0.030; pH after installation: OR = 0.01, 95%CI was 0.00-0.16, P = 0.002; Lac after installation: OR = 1.21, 95%CI was 1.06-1.37, P = 0.003]. After adjusting for the effects of age, gender, ECMO complications, arterial blood pH and Lac after installation, and CCPR time, showed that pulse pressure loss was an independent predictor of weaning failure in ECPR patients (OR = 1.27, 95%CI was 1.01-1.61, P = 0.049).@*CONCLUSIONS@#Early loss of pulse pressure after ECPR is an independent predictor of failed weaning off ECMO in ECPR patients. Strengthening hemodynamic monitoring and management after ECPR is very important for the successful weaning off ECMO in ECPR.

ABSTRACT

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

ABSTRACT

Objective:This study aims to explore the pathogenic roles of protein S-nitrosylation modification in the development of severe acute pancreatitis, and provide new insights into the molecular mechanisms driving acute pancreatitis development.Methods:Thirty two Sprague Dawley (SD) rats were randomly divided into sham operation group, mild acute pancreatitis (MAP) group, severe acute pancreatitis (SAP) group and SAP + N-nitro-L-arginine methyl ester (L-NAME) group (treated with nitric oxide synthase inhibitor), 8 rats in each group. All rats were sacrificed to take blood from heart and pancreatic tissues 24 h after model construction. Total protein S-nitrosylation modification level in pancreatic tissues was quantitated by the biotin-switch method, followed by histological evaluation via hematoxylin and eosin (HE) staining. The serum endotoxin, D-lactic acid, diamine oxidase, interleukin-6 and tumor necrosis factor-ɑ(TNF-ɑ), amylase, alanine aminotransferase, urea nitrogen and calcium ions in rat were detected. Pearson correlation analysis was used to analyze the correlation between each index and protein S-nitrosylation.Results:Compared with the sham operation group, the modification level of protein S-nitrosylation in pancreatic tissue of MAP group increased significantly ( P<0.05); Compared with MAP group, the modification level of protein S-nitrosylation in pancreatic tissue of SAP group increased significantly ( P<0.05); Compared with SAP group, the modification level of protein S-nitrosylation in pancreatic tissue of SAP + L-NAME group decreased significantly ( P<0.05). HE staining showed that the degree of pancreatic necrosis and inflammatory cell infiltration in SAP + L-NAME group were significantly weaker than those in SAP group. The concentrations of serum endotoxin, diamine oxidase, D-lactic acid, IL-6 and TNF-ɑ, amylase, alanine aminotransferase, and urea nitrogen in the MAP group were significantly higher than those in the sham operation group (all P<0.05); The above indexes in SAP group were significantly higher than those in MAP group and sham operation group (all P<0.05); The above indexes in SAP + L-NAME group were significantly lower than those in SAP group (all P<0.05). The serum IL-6 and TNF-ɑ levels in rats with acute pancreatitis were positively correlated with protein S-nitrosylation in pancreatic tissue (all P<0.05). Conclusions:Protein S-nitrosylation modification plays essential roles in the development and progression of severe acute pancreatitis.

ABSTRACT

Objective:To analyze the effect of high-flow nasal cannula (HFNC) oxygen therapy in patients with acute respiratory failure, and investigate the indicators that predict the failure of HFNC.Methods:The clinical data of 174 patients with acute respiratory failure were retrospectively analyzed. The patients were treated with HFNC in the Emergency Department of Hunan Provincial People′s Hospital from January 2018 to September 2020. The vital signs, blood gas analysis, Borg score and ROX index of patients before and one hour after HFNC application were compared, and the application effect of HFNC was judged. The HFNC failure group was defined as patients with respiratory support upgraded to non-invasive ventilation, endotracheal intubation or death within 48 h, and the indicators for predicting the HFNC failure were analyzed.Results:The failure rate of HFNC was 24.13%(42/174). There were significant differences in the heart rate, SpO 2, systolic blood pressure, diastolic blood pressure and PaO 2 of successfal group before and after the use of HFNC, t values were -8.12-4.60, all P<0.05. Multivariate Logistic regression analysis showed that the change value of systolic blood pressure was a protective factor of the failure of HFNC ( OR=0.967, 95% CI were 0.949-0.985, P<0.05). Conclusions:The application of HFNC in patients with acute respiratory failure is feasible and effective, and the change value of systolic blood pressure is an indicator to predict the failure of HFNC.

ABSTRACT

Objective:To analyze the influence of factors before initiation of extracorporeal cardiopulmonary resuscitation (ECPR) on the prognosis of patients, so as to explore the intervention timing and improvement strategy of ECPR.Methods:A retrospective analysis was performed on 29 patients who underwent ECPR in the First Affiliated Hospital of Hunan Normal University (Hunan people's Hospital)from July 2018 to April 2021. Patients were divided into the survival group ( n = 13) and death group ( n = 16) according to whether they survived at discharge. The duration of conventional cardiopulmonary resuscitation (CCPR), initial heart rate before ECPR, the ratio of out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA), and the ratio of transported cases outside the hospital were compared between the two groups. According to different CCPR time, the patients were divided into the ≤45 min group, 45-60 min group and >60 min group to compare the hospital survival and sustained return of spontaneous circulation (ROSC) rate . According to the location of cardiac arrest, the patients from emergency department and other department were divided to compare the survival of IHCA. Results:The total survival rate was 44.83%, the average duration of extracorporeal membrane oxygenation (ECMO) was 114 (33.5, 142.5) h, and the average duration of CCPR time was 60 (44.5, 80) min. The duration of ECMO was longer in the survival group than in the death group ( P = 0.001). The duration of CCPR (the time from CPR to ECMO) in the survival group was significantly shorter than that in the death group ( P = 0.010). Patients with defibrillatory rhythm had higher hospital survival rate ( P = 0.010). OHCA patients had higher mortality than IHCA patients ( P = 0.020). Mortality of patients transferred from other hospitals was higher ( P = 0.025). Hospital survival and ROSC decreased in turn by CCPR duration ≤ 45 min, 45-60 min, and > 60 min ( P = 0.001). The location of CA occurrence had no impact on the hospital survival rate of IHCA patients ( P=0.54). Conclusions:Hospital survival of ECPR is higher than that of CCPR. ECPR is effective for refractory cardiac arrest. The prognosis of ECPR is significantly related to the duration of CCPR, initial heart rate, and location of CA. Education and team training should be strengthened to improve the survival rate of ECPR.

ABSTRACT

Objective Plasma levels of matrix metalloproteinase-9 ( MMP-9 ) and serum level of high-sensitivity C reactive protein (hs-CRP) were detected to investigate their distributions between patients with stable stroke and those with asymptomatic intracranial artery stenosis and to explore their clinical significance. Methods The mean level of the serum hs-CRP of the group with recurrent stroke (2.34 mg/L)was the highest, followed by that of the group with the stable stroke( 1.45 mg/L),asymptomatic intracranial artery stenosis ( 1.31 mg/L) and control group (0.96 mg/L) ( P = 0.001 ). The level of the MMP-9 was in sequence of recurrent stroke group ( 121.82 ± 72.99 ) μg/L > asymptomaticintracranial artery stenosis group ( 119.18 ± 80.01 ) μg/L > stable stroke group( 112.76 ± 59.66) μg/L,while no statistical significance was found among groups( P = 0.947 ). However, the level of MMP-9 of three patient groups( 118.08 ± 71.06 ) μg/L was significant higher than control group( 57.55 ± 10.44 )μg/L (P <0.001 ). The spearman analysis for the relationship showed that the concentration of MMP-9 was positively associated with that of hs-CRP ( r = 0.337, P < 0.001 ). Conclusions The hs-CRP maintained a high level in stable stage of stroke. The MMP-9 level in the patients group was significant higher than control group and the level of MMP-9 was positively associated with that of hs-CRP which suggested MMP-9 might be correlated with atherosclerosis other than stroke occurrence.
