Forty critical patients with respiratory failure in the intensive care unit were randomly divided into two groups,Group A with administration of parenteral nutritino(PN) and Group B,no parenteral nutrition given.Blood gas analysis and respiratory monitoring showed that the respiratory rate,pH、PaO2、PaCO2 and HCO3- had no marked difference between the two groups.But in Group A there was a slight decrease of Pao2/FiO2 and a marked increase of A-aDO2 and the pulmonary shunt.This study indicates that the content of fat emulsion and hydrocarbon in PN may be the main factor that affects the respiratory function.
ObjectiveTo study the value of revised trauma scores (RTS), major trauma outcome study (MTOS)-RTS scores and point of care test (POCT) in the early forecast of survival time in severe multiple trauma patients.
MethodsMultiple trauma patients treated in the Emergency Department of our hospital between September and December 2015 were included in our study. We collected such data as the basic information on admission, physical signs (breath, blood pressure, state of consciousness) and POCT indexes, including pH value, hemoglobin, base excess, hematocrit value, lactic acid, sodium, anion gap, and blood glucose. We calculated each patient's RTS and MTOS-RTS scores. According to the 30-day prognosis, the patients were divided into survival group and death group. Risk factors for survival time were screened by Cox regression risk model.
ResultsSeventy-five multiple trauma patients were included in our study. Among them, there were 51 males and 24 females. Fourteen of them died. The multivariate analysis in the Cox regression risk model showed that the risk factors for the death of multiple trauma patients included MOTS-RTS score [RR=0.726, 95%CI (0.608, 0.867), P < 0.001) and POCT lactic acid level [RR=1.139, 95%CI (1.010, 1.324), P=0.037].
ConclusionMOTS-RTS combined with lactic acid level may be used in the early forecast of survival time in severe multiple trauma patients.
Objective To evaluate the relationship between the severity of neonatal infection and the activity change of cardiac enzyme. Methods A total of 102 infectious neonates in NICU were evaluated with neonatal serious illness scoring system and then divided into non-critical, critical, and extremely-critical groups. The activity of such serum myocardial enzymes as AST, ALT, LDH, CK, and CKMB was tested in the first 24 hours on admission. Comparison between groups and analyses were conducted. Resultes Myocardial enzyme of the critical and extremely-critical groups was obviously higher than that of the non-critical group (Plt;0.01). Conclusion The serious illness score of infectious neonates is closely associated with the activity change of myocardial enzyme and the level of serum myocardial enzymes has certain advantages in judging the myocardial injury and the disease severity of neonatal infection.
Objectives To explore the characteristics of thrombosis in critically ill patients with Omicron infection and the therapeutic value of prophylactic low molecular weight heparin (LMWH) treatment. MethodsA single center, retrospective cohort study included critically ill adult patients with Omicron variant of SARS-CoV-2 admitted to Peking University Third Hospital from December 7, 2022, to February 8, 2023. The patients were categorized into two groups based prophylactic LMWH. Propensity score (PS) matching was used to match patients (1: 1 ratio) based on the predefined criteria. General clinical information and laboratory parameters were compared. This study was retrospectively registered at Chinese Clinical Trail Registry (ChiCTR2300067434). ResultsFour hundred and fifty-two patients and 360 patients were included before and after PS matching. There were no statistical differences in mortality, the incidence of pulmonary embolism, arterial thrombosis or bleeding between the anticoagulation group and non-coagulation group before and after PS matching. There were 91 thrombotic events in 82 patients (18.14%), of which 54 cases (59.34%) were lower limb intermuscular vein thrombosis, 3 cases (3.30%) were pulmonary embolism, 14 cases (15.38%) were acute myocardial infarction and 3 cases (3.30%) were acute cerebral infarction. The thrombotic event resulted in the death of 5 patients. D-dimer increased in 385 cases (85.56%). On the 1st, 3rd, 6th and 9th day, the concentration of D-dimer in the anticoagulant group was higher than that in the non-anticoagulant group (P=0.006, 0.001, 0.024 and 0.006, respectively). ConclusionsAlthough thrombosis and coagulation disorders are still common complications of COVID-19, it is not the direct cause of most death in COVID-19 patients caused by Omicron. The role of prophylactic anticoagulation treatment for Omicron-infected patients needs further study.
Objective
To investigate the relationship between the gastrointestinal function and ventilator-associated pneumonia (VAP) in critically ill patients who underwent invasive mechanical ventilation.
Methods
One-hundred and fifty-three cases of critically ill patients receiving mechanically ventilation were recruited in the study. After 5 days of ventilation, the gastrointestinal function score and the C-reactive protein (CRP) of each patient were recorded. The incidence of VAP was recorded during hospitalization. According to the incidence of VAP, all patients were divided intoaVAP group and a non-VAP group. The relationship between gastrointestinal function score and the incidence of VAP was analyzed. The relationship between CRP level and severity degree of VAP was also analyzed.
Results
VAP occurred in 42 cases with the incidence of 27.45%. The gastrointestinal function score (1.9±1.0 vs. 0.8±1.0, P < 0.05) and CRP level [(52.38±12.06) mg/L vs. (36.69±11.08)mg/L, P < 0.05] were both higher in the VAP group than those in the non-VAP group. At gastrointestinal function score of 0 - 3, the CRP levels were all higher in the VAP group than those in the non-VAP group (P < 0.05). The incidence of VAP was 8.33%, 23.68%, 45.45%, and 59.09% at gastrointestinal function score of 0, 1, 2 and 3, respectively, with significant differences between each other(P < 0.05).
Conclusion
For critically ill patients receiving invasive mechanical ventilation, the more severe the damage of gastrointestinal function is, the higher the incidence of VAP is, and the more serious the disease is.
ObjectiveTo analyze the clinical characteristics and epidemiological characteristics of patients with coronavirus disease 2019 treated early in Jiangxi province.MethodsFour-night patients with coronavirus disease 2019 treated in this hospital from January 21st to 27th, 2020 were included in this study. The epidemiological and clinical data of patients after admission were collected, and laboratory tests such as blood routine, urine routine, stool routine, liver and kidney function, electrolytes, myocardial enzymes, erythrocyte sedimentation (ESR), C-reactive protein (CRP), calcitonin, coagulation, T cell subset and Chest CT were reviewed. The clinical results of common and severe/critically ill patients were compared.ResultsOf the 49 patients, 40 were common and 9 were severe/critical. Fourty-six patients had a clear history of contact with Wuhan or other areas of Hubei. The sex ratio was 2.06∶1, and the average age was 42.9 years. The symptoms were mainly fever (78.7%), cough (38.8%), and fatigue (18.4%). 28.6% (14 cases) of patients had hypertension and diabetes. Serum lymphocyte count and calcium concentration of the patients were decreased, but lactate dehydrogenase, ESR, CRP and serum amyloid A were increased in these patients. T lymphocyte subsets (CD3+, CD4+, CD8+) decreased significantly in these patients. Forty-seven patients (95.9%) had single or scattered patchy ground glass density shadows on the chest CT. Compared with common patients, the patients with severe/critical patients were older (P=0.023), hospitalized later (P=0.002), and had higher comorbidities (P=0.017). ESR (P=0.001）, CRP (P=0.010) and the serum amyloid A (P=0.040) increased significantly, while CD3+ (P<0.001), CD4+ (P=0.012), CD8+ (P=0.006) decreased significantly in severe/critical patients.ConclusionsThe patients with coronavirus disease 2019 in Jiangxi province are commonly imported from Wuhan. Severe/critical patients are older, hospitalized later, and have more medical complications and more severe systemic inflammatory reactions than common patients.
Malnutrition is directly related to the outcomes of critically ill children. Providing ideal nutritional treatment can reduce the high catabolic state caused by the critically ill, reduce oxidative damage and regulate immune response, then improving clinical prognosis. Optimized nutritional supply for critically ill children has been transformed from auxiliary support to one of the important treatment methods. Enteral nutrition is the preferred way to provide nutrition, but parenteral nutrition is the only method of supplement and replacement when the supply of enteral nutrition is insufficient or deficient. This article reviews the timing of parenteral nutrition initiation, protein and amino acids in parenteral nutrition, the mechanism of possible adverse effects in early parenteral nutrition, and issues related to parenteral nutrition in premature infants, in order to help clinicians in pediatric intensive care unit improve the evaluation and management of parenteral nutrition use.
