ObjectiveTo evaluate the predictive value of critical illness scores for hospital mortality of severe respiratory diseases in respiratory intensive care unit (ICU).MethodsThe clinical data of the patients who needed intensive care and primary diagnosed with respiratory diseases from June, 2001 to Octomber, 2012 were extracted from MIMIC-Ⅲ database. The Acute Physiology Score (APS) Ⅲ, Simplified Acute Physiology Score (SAPS) Ⅱ, Oxford Acute Severity of Illness Score (OASIS), Logistic Organ Dysfunction System (LODS), Systemic Inflammatory Response Syndrome (SIRS) and Sequential Organ Failure Assessment (SOFA) were calculated according to the requirements of each scoring system. ICU mortality was set up as primary outcome and receiver operating characteristic (ROC) analysis was performed to evaluate the predictive performances by comparing the areas under ROC curve (AUC). According to whether they received invasive mechanical ventilation during ICU, the patients were divided into two groups (group A: without invasive mechanical ventilation group; group B: with invasive mechanical ventilation group). The AUCs of six scoring systems were calculated for groups A and B, and the ROC curves were compared independently.ResultsA total of 2988 patients were recruited, male accounted for 49.4%, median age was 67 (55, 79), and ICU mortality was 13.2%. The AUCs of SAPSⅡ, LODS, APSⅢ, OASIS, SOFA and SIRS were 0.73 (0.70, 0.75), 0.71 (0.68, 0.73), 0.69 (0.67, 0.72), 0.69 (0.67, 0.72), 0.67 (0.64, 0.70) and 0.58 (0.56, 0.62). Subgroup analysis showed that in group A, the AUCs of OASIS, SAPSⅡ, LODS, APSⅢ, SOFA and SIRS were 0.81 (0.76, 0.85), 0.80 (0.75, 0.85), 0.77 (0.72, 0.83), 0.75 (0.70, 0.80), 0.73 (0.68, 0.78) and 0.63 (0.56, 0.69) in the prediction of ICU mortality; in group B, the AUCs of SAPSⅡ, APSⅢ, LODS, SOFA, OASIS and SIRS were 0.68 (0.64, 0.71), 0.67 (0.63, 0.70), 0.65 (0.62, 0.69), 0.62 (0.59, 0.66), 0.62 (0.58, 0.65) and 0.57 (0.54, 0.61) in the prediction of ICU mortality. The results of independent ROC curve showed that the AUC differences between groups A and B were statistically significant in terms of OASIS, SAPSⅡ, LODS, APSⅢ and SOFA, but there were no significant differences in SIRS.ConclusionsThe predictive values of six critical illness scores for ICU mortality in respiratory intensive care are low. Lack of ability to predict ICU mortality of patients with invasive mechanical ventilation should hold primary responsibility.
Interfacility transport of critically ill children is an important part of pre-hospital emergency care. The development of 5th generation mobile networks has brought revolutionary changes to emergency medicine, which can realize real-time sharing of information between hospitals and transfer ambulance units. In order to give full play to the advantages of superior medical institutions in diagnosis and treatment technology, equipment resources, and realize the safe and fast transfer of critically ill children, the technical specifications for the construction of interfacility transport of critically ill children’s ambulances with 5th generation mobile networks are specially formulated to standardize the team building, equipment and materials, transport process and quality control requirements for critically ill children’s ambulance transport, so as to reduce the fatality rate of critically ill children and improve the prognosis.
Objective To explore the type and frequency of oral care practice in intensive care units (ICUs) in Mainland China, and to provide evidence and suggestions for improving oral care practice. Methods Three survey methods, including mailing questionnaires to ICUs of Grade 3A hospitals, consulting experts in this field and visiting accessible ICUs, were used to survey current oral care practice in Mainland China. Results A total of 184 questionnaires were given to the subjects, of which 79 effective ones were collected, and the response rate was 42.93%. All 79 respondents considered oral care very unimportant, and 98.7% of the ICUs performed oral care in different ways. Currently, the cotton ball wipe-off method was the most frequently used for oral care (62.5%), with an average (9.1± 5.1) min per time, twice or three times daily. The mouthwashes often used were saline (76.1%), solutions containing sodium bicarbonate (22.8%), furacilin (13.9%), and hydrogen dioxide (13.9%). Conclusion The oral care practice for the critically-ill patients in ICUs of China is unsatisfactory, although it is perceived as an important item in nursing care. More evidence–based training should be given and it is necessary to establish a national oral care guideline for critically-ill patients.
ObjectiveTo summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy.MethodFive patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years.ResultAll operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good.ConclusionThe short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.
Objective To evaluate the effect of exogenous melatonin and its analogues on the prevention of delirium in critically ill patients by meta-analysis. Methods Randomized controlled trials of exogenous melatonin and its analogues in the prevention of delirium in critically ill patients were searched by computer from the Cochrane Library, PubMed, Web of Science, Embase, China National Knowledge Infrastructure, Chongqing VIP, Wanfang, and SinoMed databases. The trial group was treated with melatonin or its analogues, while the control group was treated with placebo. The retrieval period was from the establishment of database to January 14th, 2021. Two researchers independently evaluated the literature quality, and meta-analysis was performed using RevMan 5.4 software. Results A total of 11 randomized controlled trials containing 1177 patients were enrolled, including 588 patients in the trial group and 589 patients in the control group. The results showed that exogenous melatonin and its analogues could reduce the occurrence of delirium in critically ill patients [odds ratio (OR)=0.45, 95% confidence interval (CI) (0.22, 0.91), P=0.03] and shorten the time of mechanical ventilation [standard mean difference (SMD)=?0.49, 95%CI (?0.94, ?0.03), P=0.04], while might not affect the mortality rate [OR=0.73, 95%CI (0.46, 1.17), P=0.19] or length of intensive care unit stay [SMD=?0.05, 95%CI (?0.26, 0.15), P=0.61]. Conclusions The current evidence shows that exogenous melatonin and its analogues have some effect on reducing the occurrence of delirium and shortening the duration of mechanical ventilation in critically ill patients, and have no significant effect on reducing the mortality or length of intensive care unit stay. The above conclusions need to be confirmed by more high-quality studies.
ObjectiveTo compare the indirect calorimetry (IC) measured resting energy expenditure (MREE) with adjusted Harris-Benedict formula calculating resting energy expenditure (CREE) in the mechanically ventilated surgical critically ill patients and to evaluate the relationship between the resting energy expenditure (REE) with the severity of illness. MethodsTwenty-one patients undergonging mechanical ventilation for critical illness in the intensive care unit of general surgery between August 2008 and February 2010 were included in this study. Data during the study period of nutrition support were collected for computation of the severity of critical illness by acute physiology and chronic health evaluation Ⅱ scores (APACHE Ⅱ scores) and organ dysfunction scores (Marshall scores). MREE was measured by using IC of the MedGraphics CCM/D System within the first 7 d after nutrition therapy. CREE was calculated by using the HarrisBenedict formula adjusted with correction factors for illness at the same time. According to APACHE Ⅱ scores on admission, the enrolled patients were divided into two groups: APACHEⅡ score ≥20 scores group (n=8) and APACHE Ⅱ score lt;20 scores group (n=13), and the differences between MREE and CREE of patients in two groups were determined. ResultsThe reduction of variation tendency in CREE other than MREE in the enrolled patients within the first week of nutritional support was statistical significance (Plt;0.001). The CREE of patients 〔(1 984.49±461.83) kcal/d〕 was significantly higher than the MREE 〔(1 563.88±496.93) kcal/d〕 during the first week of nutritional support (Plt;0.001). The MREE on the 0, 1, 2, and 4 d after nutrition therapy were statistically significant lower than CREE at the same time interval in these patients (Plt;0.01), and the differences at the other time points were not significant (Pgt;0.05). There was a trend towards a reduction in APACHE Ⅱ and Marshall scores within the first week of nutrition therapy that reached statistical significance (Plt;0.001). During the first week of nutrition therapy, APACHEⅡ and Marshall scores of patients in ≥20 scores group were significantly higher than those in lt;20 scores group, respectively (Plt;0.05 or Plt;0.01), and the reductions of APACHE Ⅱ scores and Marshall scores were significant in patients of two groups (Plt;0.001). A significant positive correlation was found between CREE with APACHE Ⅱ scores (r=0.656, Plt;0.001) and Marshall scores (r=0.608，Plt;0.001) in patients within the first week after nutrition support. Although no statistically significant correlation was observed between MREE and APACHEⅡ scores (r=-0.045， P=0.563), a significant positive correlation was observed between MREE and Marshall scores (r=0.263, P=0.001) within the first week after nutrition therapy. There was no correlation between MREE and CREE (r=0.064, P=0.408) in patients at the same time interval. The reduction of MREE of patients in ≥20 scores group other than in lt;20 scores group was statistically significant within the first week after nutrition therapy (P=0.034). In addition, the MREE of patients in ≥20 scores group were not significantly different from those in lt;20 scores group (Pgt;0.05), and the mean CREE was not different in two groups patients within the first week of nutritional therapy 〔(1 999.55±372.73) kcal/d vs. (1 918.39±375.27) kcal/d, P=0.887〕. CREE was significantly higher than MREE of patients in ≥20 scores group within the first week except the 3 d and 5 d after nutrition therapy (Plt;0.05), while in lt;20 scores group CREE was significantly higher than MREE in patients only within the first 3 d after nutrition therapy (Plt;0.05 or Plt;0.01). MREE and CREE of patients in ≥20 scores group were not different from those in lt;20 scores group, respectively (Pgt;0.05).
