Objective To explore the diagnosis and treatment of critically ill patients suffering from obstructive sleep apnea-hypopnea syndrome ( OSAHS) . Methods Critically ill patients with OSAHS admitted in intensive care unit from January 2003 to December 2007 were retrospectively analyzed. Results Seventy-nine critically ill patients were diagnosed as OSAHS. The initial diagnosis of OSAHS was made by history requiring, physical examination, and Epworth sleepiness score evaluation. The final diagnosis was comfirmed by polysomnography thereafter. Base on the treatment of primary critical diseases, the patients were given respiratory support either with continuous positive airway pressure ( CPAP) or with bi-level positive airway pressure ventilation ( BiPAP) . Two cases died and the remaining 77 patients were cured anddischarged. Conclusions Timely diagnosis of OSAHS is important to rescue the critically ill patients. Respiratory support combined with treatment of primary critical diseases can improve the outcomes of these patients.
ObjectiveTo systematically review the incidence and influencing factors of early enteral nutritional feeding interruptions in critically ill patients. MethodsThe PubMed, Web of Science, Embase, Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect observational studies on the early enteral nutritional feeding interruptions in critically ill patients from inception to January 2, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 17.0 software. ResultsA total of 12 studies including 1 121 patients were included. Meta-analysis showed that the incidence of early enteral nutritional feeding interruptions in critically ill patients was 75.0% (95%CI 64.0% to 84.0%). Influenced by feeding intolerance, airway management, tube problems, radiological examination, and endoscopy, surgery and so on, interruptions of early enteral nutritional feeding frequently occur in critically ill patients. ConclusionCurrent evidence shows that early enteral feeding interruptions in critically ill patients are affected by many factors, and the incidence is high. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo investigate the clinical value of peripheral blood vitamin D level in predicting the outcome of weaning from mechanical ventilation in critically ill patients.MethodsA total of 130 critically ill patients who undergoing mechanical ventilation for more than 48 hours in our hospital were recruited from June 2014 to June 2017. Serum 25(OH)D3 was detected on admission and before spontaneous breathing test (SBT) meanwhile general clinical data and laboratory examination indexes were recorded. The cases were divided into a successful weaning group and a failure weaning group according to the outcome of weaning from mechanical ventilation. Logistic regression equation was used to analyze the relationship between vitamin D level and failure weaning, and a receiver operating characteristic (ROC) curve was used to analyze the predictive value for failure weaning.ResultsThere were 46 patients with failure weaning among 130 patients (35.38%). Compared with the successful weaning group, the failure weaning group had significantly higher Acute Physiology and Chronic Health EvaluationⅡ score, longer duration in intensive care unit, higher respiratory rate, higher rapid shallow breathing index, higher C-reactive protein, higher N-terminal prohormone of brain natriuretic peptide, higher serum creatinine, and significantly lower albumin (all P<0.05). 25(OH)D3 level classifications on admission and before SBT in the failure weaning group were worse than those in the successful weaning group (P<0.05). 25(OH)D3 levels of the failure weaning group were lower than those of the successful weaning group [on admission: (18.16±4.33) ng/ml vs. (21.60±5.25) ng/ml, P<0.05; before SBT: (13.50±3.52) ng/mlvs. (18.61±4.30) ng/ml, P<0.05]. Multivariate logistic regression analysis showed that 25(OH)D3 levels on admission and before SBT were independent risk factors for failure weaning (OR values were 2.257 and 2.613, respectively, both P<0.05). ROC curve analysis showed that areas under ROC curve were 0.772 and 0.836, respectively, with sensitivities of 80.3% and 85.2%, specificities of 69.0% and 71.0%, respectively.Conclusions25(OH)D3 deficiency or insufficiency is common in critically ill patients. The lower the level of vitamin D, the higher the risk of failure weaning. So it may be an independent predictor of failure weaning.
Acute kidney injury is a common complication and is associated with multiple organ dysfunction syndrome among critically ill patients in intensive care unit. Once renal replacement therapy in required, the mortality rate was high. Using slow and uninterrupted clearance of retained fluid and toxins, continuous renal replacement therapy (CRRT) can avoid hemodynamic instability while provide acid-base, electrolytes, and volume homeostasis. For decades, CRRT has become the dominant form of renal replacement therapy as well as multiple organ support in critically ill patient with acute kidney injury. However, there remains wide practice variation in the CRRT care when clinicians take into account the needs of individual patients, available resources, and limitations unique to an institution or type of practice, despite evidences to guide practice. In addition, CRRT is a complex technology that is resource-intensive, costly, and requires specialized training by health providers.Taiwan Society of Critical Care Medicine organized a group of experts in critical care and nephrology to review the recommendations and provide their clinical practice and concerns to write this operational manual. The purpose of this manual is to provide step-by-step instructions on the practice of CRRT and troubleshooting. In addition, it is designed to help the newbies to carry out this complex treatment correctly and efficiently. We hope that this operational manual is of value to improve clinical skills, quality of care, and patient safety.
Continuous renal replacement therapy (CRRT) is the treatment of choice for critically ill patients with hemodynamic instability who require renal replacement therapy. This review summarizes the impact of CRRT treatment on nutritional support in critically ill patients, including: energy increase caused by citrate-based anticoagulants, energy loss caused by glucose-free replacement fluid and dialysate, a large amount of amino acids loss in the effluent, and the influences on the way of lipid emulsion administration, capacity, electrolyte, vitamins, and trace elements. It is hoped that the intensive care unit doctors, nephrologists, and nutritionists can fully cooperate to determine the CRRT prescription and the nutritional support prescription.
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.
In recent years, with the development of neuroimaging and the improvement of people’s awareness, the incidence of cerebral venous sinus thrombosis (CVST) has been increasing year by year. CVST with venous infarction or haemorrhage is severe, accounting for about 60% of CVST, and its clinical manifestations are serious. The current therapies including anticoagulation and intravascular treatment have not significantly improved the prognosis of severe CVST patients. The incidence of long-term poor prognosis (modified Rankin scale score≥2) is up to 56.1%. Recent research indicates that inflammation may be an important factor leading to severe CVST and is significantly associated with poor prognosis. Anti-inflammatory treatment with glucocorticoids may provide a novel method for severe CVST, but further clinical studies are needed to verify it. This paper introduces the relationship between inflammation and severe CVST in order to explore the feasibility of glucocorticoid for severe CVST.
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.

Objective To explore the influence of different withdrawal time of trachea cannula on percutaneous dilational tracheostomy (PDT) in critically ill patients. Methods In this study, we retrospectively analyzed the clinical data of 185 critically ill patients experienced PDT, who had been admitted to the adult mixed ICU of Xiaolan Hospital of Southern Medical University from January 2015 to July 2017. The patients were divided into an early PDT group (EPDT group) and a delayed PDT group (DPDT group) according to the timing of withdrawing trachea cannula. Operation information such as operation time, blood loss and the incidence of complications were collected and compared between the two groups. Results Between the EPDT group and the DPDT group, there were no obvious differences in operation time (minutes: 6.5±2.6 vs. 7.3±3.5), amount of blood loss (ml: 5.2±2.8 vs. 6.0±3.4) or conversion to traditional operation (1.9% vs. 2.4%) (all P>0.05). Compared with the EPDT group, the DPDT group patients experienced more fluctuation of intraoperative vital signs, used more dose of sedative and analgesic drugs, and experienced higher occurrence of aspiration (18.3%vs. 5.6%), balloon burst (13.4% vs. 2.9%), guide-wire placing difficulty (11.0% vs. 1.9%) and tracheostomy cannula placing difficulty (14.6% vs. 2.9%) (all P<0.05). There were no statistical significances in postoperative complications such as postoperative-hemorrhage, pneumothorax, pneumoderm, the posterior tracheal injury or incision infection between the two groups (allP<0.05). More patients acquired postoperative pulmonary infection in the DPDT group than the EDPD group (12.2%vs. 5.8%, P>0.05), and there was no statistical significances in mechanical ventilation time between the two groups (days: 5.5±3.0vs. 6.0±2.5, P>0.05). Conclusions The operation and complications of PDT in critically ill patients are influenced by the timing of withdrawing trachea cannula. The standard procedure of withdrawing trachea cannula preoperatively may offer better clinical operability and lower technical risk.
