ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.
Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.
ObjectiveTo observe the clinical characteristics, the characteristics of organ dysfunction and death related factors in the natural course of severe acute pancreatitis (SAP). MethodsThe data of 302 cases of SAP from January 1999 to June 2007 in our hospital were retrospective analyzed. The APACHEⅡscore, state of each organ, and death related factors were recorded and analyzed according to the admission and on 1, 3, 5, 7, 14, and 28 d after admission, a total of 7 time points. ResultsIn natural course of SAP, the APACHEⅡscore took on a double-peak type distribution, the peaks appearing nearly about one week and two weeks after the onset of SAP. Systemic inflammatory response syndrome (SIRS), hypoxemia, metabolic acidosis, hyperglycemia, and abdominal compartment syndrome were the main causes of early organ failure. Incidence of organ failure and infection increased significantly for patients with intestinal paralysis lasting longer than five days. The most affected organ failure was followed by respiratory organs, peripheral circulation, kidneys, and gastrointestinal tract. The mortality rate increased significantly for patients with organ failure more than 48 hours. Four cases of death (9.5%) caused by severe shock and cardiac arrest within 24 h after admission; 6 deaths (14.3%) led by persistent shock with ARDS or acute renal failure within 24-72 h; 14 cases of death (33.3%) arose from 3-10 d after onset, mainly for acute respiratory distress syndrome (ARDS), acute renal failure associated with multiple organ dysfunction syndrome (MODS); 18 cases (42.8%) of the death arose on 10 d after the onset, mainly for the MODS caused by intra-abdominal infections, bleeding, pancreatic fistula, and biliary fistula. ConclusionsThe natural course of SAP can be divided into three phases:systemic inflammation, systemic infection, and recovery. Duration of intestinal paralysis is an important factor affecting the natural history of SAP. Early complications in patients with organ failure appeared as SIRS, metabolic acidosis, hyperglycemia, and abdominal hypertension. MODS led by SIRS is the leading cause in early death of SAP; MODS caused by pancreas and peripancreatic tissue infections, abdominal bleeding, pancreatic fistula, and biliary fistula are the main death factor in the late phase. Early recovery of gastrointestinal function can reduce the incidence of MODS.
ObjectiveTo systematically evaluate the efficacy of high-flow nasal cannula oxygen therapy (HFNC) in post-extubation intensive care unit (ICU) patients.MethodsThe PubMed, Embase, Cochrane Library, CNKI, WanFang, VIP Databases were searched for all published available randomized controlled trials (RCTs) or cohort studies about HFNC therapy in post-extubation ICU patients. The control group was treated with conventional oxygen therapy (COT) or non-invasive positive pressure ventilation (NIPPV), while the experimental group was treated with HFNC. Two reviewers separately searched the articles, evaluated the quality of the literatures, extracted data according to the inclusion and exclusion criteria. RevMan5.3 was used for meta-analysis. The main outcome measurements included reintubation rate and length of ICU stay. The secondary outcomes included ICU mortality and hospital acquired pneumonia (HAP) rate.ResultsA total of 20 articles were enrolled. There were 3 583 patients enrolled, with 1 727 patients in HFNC group, and 1 856 patients in control group (841 patients with COT, and 1 015 with NIPPV). Meta-analysis showed that HFNC had a significant advantage over COT in reducing the reintubation rate of patients with postextubation (P<0.000 01), but there was no significant difference as compared with that of NIPPV (P=0.21). It was shown by pooled analysis of two subgroups that compared with COT/NIPPV, HFNC had a significant advantage in reducing reintubation rate in patients of postextubation (P<0.000 01). There was no significant difference in ICU mortality between HFNC and COT (P=0.38) or NIPPV (P=0.36). There was no significant difference in length of ICU stay between HFNC and COT (P=0.30), but there had a significant advantage in length of ICU stay between HFNC and NIPPV (P<0.000 01). It was shown by pooled analysis of two subgroups that compared with COT/NIPPV, HFNC had a significant advantage in length of ICU stay (P=0.04). There was no significant difference in HAP rate between HFNC and COT (P=0.61) or NIPPV (P=0.23).ConclusionsThere is a significant advantage to decrease reintubation rate between HFNC and COT, but there is no significant difference in ICU mortality, length of ICU stay or HAP rate. There is a significant advantage to decrease length of ICU stay between HFNC and NIPPV, but there is no significant difference in ICU mortality, reintubation rate or HAP rate.

Objective A comparative study of in-hospital mortality and risk factors of ventilator-associated pneumonia (VAP) caused by carbapenem-resistant gram-negative bacteria (CRGNB) and non-carbapenem-resistant gram-negative bacteria (nCRGNB) in China was conducted to investigate whether there is a higher in-hospital mortality of VAP caused by CRGNB and its unique associated risk factors. Methods Relevant literatures published at home and abroad in PubMed, EMBASE, Cochrane library, Web of Science, CNKI and Wanfang databases were retrieved from the date of establishment to June 1, 2021, and the quality of the included literatures was evaluated using Newcastle-Ottawa scale. Meta-analysis of literatures meeting the criteria was performed using RevMan 5.3 software. Results A total of 5 literatures were included, all of which were case-control studies with a total of 574 cases, including 302 cases in the CRGNB group and 272 cases in the nCRGNB group. The results showed that the in-patient mortality of VAP caused by CRGNB infection was significantly increased compared with that of VAP caused by nCRGNB infection (OR=2.51, 95%CI 1.71 - 3.67, P<0.00001). Risk factor analysis of CRGNB infection showed that statistically significant risk factors included mechanical ventilation duration ≥7 days (OR=2.66, 95%CI 1.23 - 5.75, P=0.01), secondary intubation (OR=4.48, 95%CI 2.61 - 7.69], P<0.00001), combined with antibiotics (OR=2.83, 95%CI 1.76 - 4.54, P<0.0001), using carbapenem antibiotics (OR=2.78, 95%CI 1.76 - 4.40, P<0.0001). In addition, two studies showed that tigecycline was sensitive to CRGNB in vitro. Conclusions Compared with nCRGNB-induced VAP, CRGNB infection significantly increases the in-hospital mortality of VAP patients in China, indicating that the in-hospital mortality of CRGNB infection is related to drug resistance, and had little relationship with region and drug resistance mechanism. Among them, mechanical ventilation duration ≥7 days, secondary intubation, combined use of antibiotics and carbapenem antibiotics are risk factors for CRGNB infection in VAP patients. Tigecycline is sensitive to most CRGNB strains in China and is an important choice for the treatment of CRGNB in China.
Abstract: Objective To explore the inhospital mortalityrelated risk factors in the patients undergoing offpump coronary artery bypass grafting (OPCAB). Methods We retrospectively analyzed the clinical data of 215 patients undergoing OPCAB in our hospital from November 2007 to November 2008. There were 171 males and 44 females aged between 40 and 85 years old. Among them, there were 47 patients older than 70 years old. All of them were coronary artery disease (CAD) patients with triple vessel disease. We adopted univarialble analysis and logistic multivariable regression analysis to screen the risk factors for the mortality of OPCAB. Results Six patients died in hospital after OPCAB with a mortality rate of 2.79% (6/215). No renal dysfunction or respiratory failure occurred. The rate of reoperation for bleeding was 4.65% (10/215) and all the 10 patients having undergone reoperation were alive. A total of 209 patients were all alive after 1year follow-up. The results of logistic multivariable regression analysis showed that New York Heart Association (NYHA) Ⅲ and Ⅳ heart function (OR=42.116，95% CI 3.319 to 534.465，P=0.004) and mechanical ventilation duration (OR=1.007，95%CI 1.001 to 1.013，P=0.028) were independent risk factors for inhospital mortality of OPCAB. Conclusion OPCAB is an effective and safe treatment for CAD with triple vessel disease. NYHA Ⅲ and Ⅳ heart function and mechanical ventilation time after OPCAB are the risk factors for OPCAB inhospital mortality, yet, needs further study with large sample.
【Abstract】ObjectiveTo compare the reliability of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and APACHE Ⅲ to estimate mortality of critical patients in abdominal surgery. MethodsTwo hundred and sixtyone critical patients in abdominal surgery were included in this study. The clinical data of the first day in ICU were collected and evaluated with both APACHE Ⅱand APACHE Ⅲ prognostic systems and statistical analysis were performed. Probability of survival (Ps) was compared with actual mortality. ResultsThe scores of APACHE Ⅱ and APACHE Ⅲ of death group were significantly higher than those of survival group respectively (P＜0.01). The actual mortality of patients whose Ps was no more than 0.5 was higher than that whose Ps was over 0.5 (P＜0.01). With two prognostic systems, the scores and mortality were the highest in pancreatitis patients and the lowest in patients with gastrointestinal malignant tumor. ConclusionAPACHE Ⅱ and APACHE Ⅲ prognostic systems can be effectively applied to the estimation of mortality of critical patients in abdominal surgery. For certain diagnostic categories, APACHE Ⅲ is better than APACHE Ⅱprognostic system.
Objective To investigate the correlation between monocyte-lymphocyte ratio (MLR) and intensive care unit (ICU) results in ICU hospitalized patients. Methods Clinical data were extracted from Medical Information Mart for Intensive Care Ⅲ database, which contained health data of more than 50000 patients. The main result was 30-day mortality, and the secondary result was 90-day mortality. The Cox proportional hazards model was used to reveal the association between MLR and ICU results. Multivariable analyses were used to control for confounders. Results A total of 7295 ICU patients were included. For the 30-day mortality, the hazard ratio (HR) and 95% confidence interval (CI) of the second (0.23≤MLR<0.47) and the third (MLR≥0.47) groups were 1.28 (1.01, 1.61) and 2.70 (2.20, 3.31), respectively, compared to the first group (MLR<0.23). The HR and 95%CI of the third group were still significant after being adjusted by the two different models [2.26 (1.84, 2.77), adjusted by model 1; 2.05 (1.67, 2.52), adjusted by model 2]. A similar trend was observed in the 90-day mortality. Patients with a history of coronary and stroke of the third group had a significant higher 30-day mortality risk [HR and 95%CI were 3.28 (1.99, 5.40) and 3.20 (1.56, 6.56), respectively]. Conclusion MLR is a promising clinical biomarker, which has certain predictive value for the 30-day and 90-day mortality of patients in ICU.
Objective To explore the thromboembolic events and mortality in patients with different types of severe pneumonia, and to analyze the related high-risk factors. Methods A total of 161 severe pneumonia patients who admitted in intensive care unit from January 2018 to February 2023 were included in the study. The patients were divided into a COVID-19 group (n=88) and a community-acquired pneumonia (CAP) group (n=73) according to the type of pneumonia, and divided into a thrombosis group and a non-thrombosis group according to the occurrence of thrombosis. The patients were followed-up until discharge or in-hospital death, registering the occurrence of thrombotic events. Results During the in-hospital stay, 32.9% of CAP and 36.4% of COVID-19 patients experienced thrombotic events (P>0.05). In CAP group all the events (including 24 paitents) were venous thromboses, while in COVID-19 group 31 patients were venous and 3 were arterial thromboses (2 were cerebral infarction, and 1 with myocardial infarction). There were statistically significant difference in gender, age, venous thromboembolism score (VTE score), activated partial thromboplastin time (APTT), and procalcitonin (PCT) between the TE group and the Non-TE group. Logistic regression analysis showed that thrombotic events was associated with sex, age and APTT; gender (female: OR=2.47, 95%CI 1.13 - 5.39, P<0.05) and age (OR=1.04, 95%CI 1.01 - 1.07, P<0.05) were positively associated with thrombotic events. During the in-hospital follow-up, 44.3% of CAP patients and 42.5% of COVID-19 patients died (P>0.05). Receiver operator characteristic (ROC) curve analysis showed that APACHEⅡ score was more accurate in predicting mortality of severe pneumonia, and the area under the ROC curve (AUC) was 0.77 (95%CI 0.70 - 0.84, sensitivity 74.3%, specificity 68.1%), the AUC of the VTE score was 0.61 (95%CI 0.53 - 0.70, Sensitivity 31.4%, specificity 81.7%); the AUC of the creatinine was 0.64 (95%CI 0.56 - 0.73, sensitivity 72.9%, specificity 51.2%). While the Kappa value for kidney disease was 0.409 (P<0.05) presenting moderate consistency. Conclusions The incidence of thromboembolic events and mortality are high in patients with different types of severe pneumonia. Thrombophilia was associated with sex, age, and APTT. APACHEⅡ score, VTE score, and creatinine value were independent risk factors for predicting death from severe pneumonia.
