ABSTRACT
Objective:To investigate the effects of extracorporeal carbon dioxide removal (ECCO 2R) combined with continuous renal replacement therapy (CRRT) on respiratory efficiency and diaphragm function in patients with acute respiratory distress syndrome (ARDS) received mechanical ventilation. Methods:A prospective randomized controlled study was conducted. Sixty patients with mild to moderate ARDS admitted to the department of respiratory and critical care medicine of Henan Provincial People's Hospital from January 2019 to January 2021 were enrolled, and they were divided into observation group and control group according to the random number table method, with 30 cases in each group. All patients received antibiotics, anti-inflammatory, and mechanical ventilation therapy. On this basis, the observation group received ECCO 2R and CRRT, while the control group received bedside CRRT. Baseline data including gender, age, etiology, acute physiology and chronic health evaluationⅡ(APACHEⅡ), etc., were recorded. Arterial blood gas analysis [including arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), and oxygenation index (PaO 2/FiO 2)] was performed at 12 hours and 24 hours during the treatment, and respiratory mechanics parameters [including tidal volume, respiratory rate, maximum expiratory pressure (MEP), and maximum inspiratory pressure (MIP)] were recorded, and rapid shallow breathing index (RSBI) was calculated. The levels of glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and superoxide dismutase (SOD) in serum were detected by enzyme-linked immunosorbent assay (ELISA). Diaphragm thickness and diaphragm activity were measured by ultrasonography at 24 hours during the treatment. Results:There were no significantly differences in age, gender, etiology, and APACHEⅡ score between the two groups, indicating that the baseline data of the two groups were balanced and comparable. Compared with the 12 hours after treatment, the PaO 2 and PaO 2/FiO 2 in the observation group significantly increased, PaCO 2 significantly decreased, RSBI significantly decreased, MEP and MIP significantly increased, and serum GSH-Px and MDA significantly decreased, while SOD significantly increased at 24 hours during the treatment. In the control group, only PaCO 2 significantly decreased. Compared with the control group, the PaCO 2 significantly decreased in the observation group at 12 hours and 24 hours [mmHg (1 mmHg≈0.133 kPa): 55.05±7.57 vs. 59.49±6.95, 52.77±7.88 vs. 58.25±6.92, both P < 0.05], but no significantly differences in PaO 2 and PaO 2/FiO 2. Compared with the control group, the observation group showed significant decreases in RSBI at 12 hours and 24 hours (times·min -1·L -1: 85.92±8.83 vs. 90.38±3.78, 75.73±3.86 vs. 90.05±3.66, both P < 0.05), significant increases in MEP and MIP [MEP (mmH 2O, 1 mmH 2O≈0.01 kPa): 86.64±5.99 vs. 83.88±4.18, 93.70±5.59 vs. 85.04±3.73; MIP (mmH 2O): 44.19±6.66 vs. 41.17±3.13, 57.52±5.28 vs. 42.34±5.39, all P < 0.05], and significant decreases in serum GSH-Px and MDA [GSH-Px (mg/L): 78.52±8.72 vs. 82.10±3.37, 57.11±4.67 vs. 81.17±5.13; MDA (μmol/L): 7.84±1.97 vs. 8.71±0.83, 3.67±0.78 vs. 8.41±1.09, all P < 0.05], as well as a significant increase in SOD (U/L: 681.85±49.24 vs. 659.40±26.47, 782.32±40.56 vs. 676.65±51.97, both P < 0.05). Compared with the control group, the observation group showed significant increases in diaphragm thickness and diaphragm activity at 24 hours of treatment [diaphragm thickness (cm): 1.93±0.28 vs. 1.40±0.24, diaphragmatic thickening fraction: (0.22±0.04)% vs. (0.19±0.02)%, quiet breathing diaphragm displacement (cm): 1.42±0.13 vs. 1.36±0.06, deep breathing diaphragm displacement (cm): 5.11±0.75 vs. 2.64±0.59, all P < 0.05]. Conclusion:ECCO 2R combined with CRRT can reduce work of breathing and oxidative stress levels in ARDS patients receiving non-invasive ventilation, and protect diaphragm function.
ABSTRACT
Objective:To explore the predictive value of HACOR score [heart rate (H), acidosis (A), consciousness (C), oxygenation (O), and respiratory rate (R)] on the clinical outcome of non-invasive positive pressure ventilation in patients with pulmonary encephalopathy due to chronic obstructive pulmonary disease (COPD).Methods:A prospective study was conducted. The patients with COPD combined with pulmonary encephalopathy who were admitted to Henan Provincial People's Hospital from January 1, 2017 to June 1, 2021 and initially received non-invasive positive pressure ventilation were enrolled. Besides non-invasive positive pressure ventilation, standard medical treatments were delivered to these patients according to guidelines. The need for endotracheal intubation was judged as failure of non-invasive ventilation treatment. Early failure was defined as the need for endotracheal intubation within 48 hours of treatment, and late failure was defined as the need for endotracheal intubation 48 hours and later. The HACOR score at different time points after non-invasive ventilation, the length of intensive care unit (ICU) stay, the total length of hospital stay, and the clinical outcome were recorded. The above indexes of patients with non-invasive ventilation were compared between successful and failed groups. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive effect of HACOR score on the failure of non-invasive positive pressure ventilation in the treatment of COPD with pulmonary encephalopathy.Results:A total of 630 patients were evaluated, and 51 patients were enrolled, including 42 males (82.35%) and 9 females (17.65%), with a median age of 70.0 (62.0, 78.0) years old. Among the 51 patients, 36 patients (70.59%) were successfully treated with non-invasive ventilation and discharged from the hospital eventually, and 15 patients (29.41%) failed and switched to invasive ventilation, of which 10 patients (19.61%) were defined early failure, 5 patients (9.80%) were late failure. The length of ICU and the total length of hospital stay of the non-invasive ventilation successful group were significantly longer than those of the non-invasive ventilation failure group [length of ICU stay (days): 13.0 (10.0, 16.0) vs. 5.0 (3.0, 8.0), total length of hospital stay (days): 23.0 (12.0, 28.0) vs. 12.0 (9.0, 15.0), both P < 0.01]. The HACOR score of patients at 1-2 hours in the non-invasive ventilation failure group was significantly higher than that in the successful group [10.47 (6.00, 16.00) vs. 6.00 (3.25, 8.00), P < 0.05]. However, there was no significant difference in HACOR score before non-invasive ventilation and at 3-6 hours between the two groups. The ROC curve showed that the area under the ROC curve (AUC) of 1-2 hour HACOR score after non-invasive ventilation for predicting non-invasive ventilation failure in COPD patients with pulmonary encephalopathy was 0.686, and the 95% confidence interval (95% CI) was 0.504-0.868. When the best cut-off value was 10.50, the sensitivity was 60.03%, the specificity was 86.10%, positive predictive value was 91.23%, and negative predictive value was 47.21%. Conclusions:Non-invasive positive pressure ventilation could prevent 70.59% of COPD patients with pulmonary encephalopathy from intubation. HACOR score was valuable to predict non-invasive positive pressure ventilation failure in pulmonary encephalopathy patients due to COPD.
ABSTRACT
Objective:To systematically analyze the influence of early removal of urinary catheters on urinary complications in middle-aged and elderly patients after transurethral resection of the prostate.Methods:Randomized controlled trials or clinical controlled trials on early removal of urinary catheters in patients after transurethral resection of the prostate were retrieved from PubMed, Embase, the Cochrane Library, the Web of Science, CNKI, Wanfang Data, VIP database and CBM.RevMan 5.3 was used to analyzed the data.Results:Nine randomized controlled trials and one controlled clinical trial involving a total of 1529 patients were included.The results of meta-analysis showed that there was a significant difference between catheter removal within three days after surgery and removal 4-7days after surgery in the incidence of urinary tract infections[ OR=0.34, 95% CI(0.20-0.58), P<0.01], but there was no significant difference in secondary hemorrhage[ OR=0.86, 95% CI(0.44-1.66), P>0.05].There was no significant difference in the incidence of re-catheterization or secondary hemorrhage between ≤24 hours and 2-3 days after surgery[ OR=1.32, 95% CI(0.57-3.06), P>0.05; OR=3.18, 95% CI(0.32-31.56), P>0.05]. Conclusions:Early postoperative catheter removal(within 3 days)has a clear advantage in reducing the incidence of urinary tract infections, and urinary catheter removal within 24 hours does not increase the incidence of re-catheterization or secondary hemorrhage compared with removal after 24 hours.
ABSTRACT
Objective:To evaluate the application value of electrical impedance tomography(EIT)imaging combining bedside bronchoscopy sputum suction by observing the changes of pulmonary ventilation, tidal volume and dynamic pulmonary compliance after bedside bronchoscopy sputum suction in elderly stroke-associated pneumonia(SAP).Methods:A randomized controlled study was conducted.Patients with SAP admitted to the respiratory intensive care unit of Henan Provincial People's Hospital from January 2017 to December 2018 were enrolled as research objects.They were divided into the control group versus observation group with the only difference in receiving bedside bronchoscope sputum suction replacing control's receiving conventional sputum suction.Impedance imaging region of interest 4(ROI4)values collected by using EIT at admission and 1, 3, 5 days after fiberoptic bronchoscope sputum suction were compared between the two groups.Meanwhile, the tidal volume, dynamic lung compliance, the duration of mechanical ventilation and hospitalization time in intensive care unit were recorded in the two groups.Results:A total of 78 patients meeting an inclusion and exclusion criterion were enrolled, with 37 cases in the control group and 41 cases in the observation group.Compared with control group, the bronchoscope sputum suction group showed the significantly increased regional gas distribution values(2.24±0.77% vs.0.49±0.65%, 7.05±0.77% vs.2.49±0.87%, 12.34±1.47% vs.5.57±0.50%, t=10.85, 24.56 and 26.54, respectively, all P<0.001)at 1, 3, 5 days after fiberoptic bronchoscope sputum suction.The tidal volume and dynamic lung compliance were significantly higher in the observation group than in the control group at 1, 3, 5 days after fiberoptic bronchoscope sputum suction.The duration of mechanical ventilation and hospitalization time in the intensive care unit were shorter in the observation group than in the control group(12.22±0.88 d vs.14.65±0.92 d, 18.41±1.12 d vs.21.14±1.06 d, t=11.91 and 11.01, both P< 0.001). Conclusions:For patients with SAP, an intermittent bedside fiberoptic bronchoscope sputum suction can effectively improve the pulmonary ventilation in the dorsal area, optimize pulmonary respiratory dynamics, facilitate the early withdrawal of the mechanic ventilation, and shorten the hospitalization time in the intensive care unit.
ABSTRACT
Objective To explore the effect of a mobile-phone based two-way referral system on the timing of myocardial reperfusion and on a prognosis of patients with ST segment elevation myocardial infarction(STEMI). Methods Patients with STEMI were divided into an intervention group whose first admission clinics were equipped with a telemedicine system at the first medical contact(FMC) ,and a control group without a telemedicine system at FMC. The rate of heart failure and cardiac death during hospitalization ,every time point of transporting process ,the value of left ventricular ejection fractions(LVEF)measured at 24 h ,and length of hospital stay were collected and compared. Results In comparison of intervention versus control group ,the timing of myocardial reperfusion at every time point was shorter ( P < 0.05 ) ,the value of LVEF within 24 h was significantly lower[(46.8 ± 3.9)%]vs[(50.3 ± 5.1)%](t= 2.32 ,P< 0.05) ,the cardiac mortality was lower(4% vs 7%) ,without statistical significance(χ2=0.19 ,P=0.66) ,and the length of hospital stay were lower[(6.35 ± 3.68)d]vs[(8.64 ± 5.19)d]without statistical significance (t= 2.75 ,P=0.01). Conclusions A mobile-phone based telemedicine can significantly shorten the time delay of myocardial reperfusion in patients with STEMI ,improve heart function in acute stage ,and reduce the length of hospital stay.
ABSTRACT
Objective To evaluate the predicting value of circulating miRNAs for sepsis secondary to pneumonia in elderly patients.Methods From April 2016 to January 2017,44 cases with sepsis secondary to pneumonia,52 elderly patients with pneumonia and 21 healthy older adults as control were involved in this study.The expression levels of MiRNA-150 5p,miRNA-25-3p,miRNA-122 5p and miRNA-223-3p in plasma were evaluated by fluorescence quantitative PCR.The demographic characteristics,sequential organ failure assessment (SOFA)scores,prognosis and days stayed in ICU were recorded.The area under the receiver operating charaeteristic(ROC)curve was used to calculated the specificity and sensitivity of miRNA in identifying sepsis-associated pneumonia.Results There were significantly differences among levels of circulating miRNA-223-3p in pneumonia,sepsis and healthy control groups(F =36.441,P =0.000),△CT values were 2.39 ± 1.36,1.44± 1.43,and 4.58 ± 0.91,respectively.The relative expression levels of miRNA-223-3p in the three groups were significantly different (P =0.000),which were 0.189 (0.107,0.367),0.361 (0.221,0.735),and 0.044 (0.022,0.061),respectively.The AUC of miRNA-223-3p for predicting sepsis from pneumonia was 0.964(95 %CI =0.925 1.000).At a cutoff value of 2.759,miRNA-223-3p yielded a sensitivity of 82.9% and a specificity of 100.0%.Conclusions MiRNA-223-3p expression is up-regulated in patients with sepsis secondary to pneumonia compared to that of patients with pneumonia,and it could be used to predict sepsis associated pneumonia.
ABSTRACT
Objective To investigate the abnormal expression of proto-oncogene YES-associated protein (YAP) in gastric cancer tissues in the elderly and its correlation with poor prognosis.Methods Clinical data of 80 elderly patients with gastric cancer treated in our hospital from March 2011 to October 2014 were statistically analyzed.Results The positive expression rate of YAP was significantly higher in gastric carcinoma than in adjacent tissues [71.3% (57/80) vs.13.8% (11/80),P<0.05].The positive expression of YAP were significantly associated gastric tumor size,tumor stage,invasion depth and lymph node metastasis (all P<0.05),but had no correlation with tumor differentiation (P>0.05).The 5-year survival rate was significantly lower in patients with YAP-positive expression than in patients with YAP-negative expression (P < 0.05),but the differences in 1-year,3-year survival rates were not significant between the two groups (all P>0.05)The YAP expression,tumor stage,lymph node metastasis were significantly associated with the prognosis of gastric cancer in patients (all P<0.05).Conclusions YAP-positive expression rate is significantly higher in gastric cancer tissues than in adjacent tissues in the elderly,which indicates poor prognosis of patients with gastric cancer.
ABSTRACT
Objective To evaluate the efficacy and safety of tulobuterol patch in the treatment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) in the elderly. Methods Totally 165 elderly patients with moderate to severe AECOPD were divided into trial group and control group randomly.83 patients of trial group were treated with tulobuterol patch,2 mg once a day,and fluticasone inhalation 250 μg twice a day; 82 patients of control group were treated with inhalation of salmeterol/fluticasone 250 μg/50 μg twice a day.Basic therapy was the same in two groups. Results After 10-14 days' treatment,forced expiratory volume in one second(FEV1),peak expiratory flow (PEF),6-min walking distance and symptom scores were ( 1.30 ± 0.31 ) L,(245.3 ± 56.1 ) L/min,(263.0±53.2)m,(33.2±12.1)scores in trial group,and (1.21±0.23)L,(213.9±58.4) L/min,(230.0±45.6)m,(37.8± 14.5) scores in control group,respectively.The lung function,6 minute walk distancc and symptom score were improved (t=2.120,3.521,4.279,2.212,all P<0.05).The frequencies of rescue medication,waking-up suffocating at night and the days of hospital stay were deceased significantly in trial group as compared with control group[(2.5 ± 0.6) time/d,( 1.8 ± 0.5)time/week,(12.9±1.6)dvs.(2.90.8) time/d,(2.2±0.7) time/week,(14.1±1.8) d,t=3.610,4.219,4.524,all P<0.05].The incidence of adverse reactions was not significant difference between two groups[8 cases(9.6%)vs.7 cases(8.5%),P>0.05] and the adverse reactions were mild.Conclusions Tulobuterol patch is a newly formulated,effective and safe medication for the treatment of acute exacerbation of AECOPD.
