RESUMO
BACKGROUND: There are significant differences in the incidence and risk factors of tumor patients, and there is no relevant statistical data. Therefore, this study aims to clarify the incidence and risk factors of acute kidney injury (AKI) in malignant tumor patients and compare critically ill patients with non-critically ill patients. METHODS: Relevant literature on the occurrence of AKI in malignant tumors was retrieved from databases. Two authors independently screened and evaluated the eligibility and quality of the literature and extracted the data. The Stata 12.0 software was used for meta-analysis. RESULTS: A total of 3922 articles were initially retrieved, and 24 articles were finally included, 8 of which were about critically ill malignant tumor patients, and 16 were about malignant tumor patients. Among the 4107 patients included in the 8 studies on critically ill malignant tumors, 1932 developed AKI, with an incidence rate of 52% (95%CI 34-70%, I2 = 99%). The risk factors for AKI in critically ill malignant tumor patients were sepsis and hypovolemia, which were different from those in non-critically ill patients. Among the 292,874 patients included in the 16 studies on malignant tumors, 51,211 developed AKI, and the combined incidence rate was 24% (95%CI 17-30%, I2 = 100%). The risk factors for AKI in critical malignant tumor patients were sepsis and hypovolemia. CONCLUSION: This meta-analysis shows that the incidence of AKI in critically ill malignant tumor patients is consistent with that in other critically ill patients, and independent risk factors are sepsis and hypovolemia. The incidence of AKI in malignant tumor patients is higher than that in other patients, and tumor is a risk factor for AKI. This study has been registered in INPLASY (INPLASY202320079),Registered February 18,2023.

Objective:A meta-analysis was conducted to investigate the risk factors of interstitial lung disease in patients with RA to provide a reliable reference for clinical practice.Methods:Publications of the China Knowledge Network, Vipshop, Wanfang, China Biomedical Literature Database, EMbase, PubMed, and Cochrane Library databases were searched to obtain literature on cohort studies and case-control studies for risk factors for RA complicated with interstitial lung disease from the time of database creation until December 31, 2022. Literature screening, information extraction, and final quality evaluation were performed independently by two investigators. The extracted data were analyzed using RevMan 5.3 software.Results:A total of 31 studies with a total of 26 747 patients were included in this study, of which 4 799 patients(17.94%) were patients with RA complicated with interstitial lung disease. A total of 12 risk factors were obtained included: advanced age [ OR (95% CI) =1.07(1.04, 1.09), P<0.001], high age at onset [ OR (95% CI) =2.11(1.17, 3.82), P=0.010], male [ OR (95% CI) =1.95(1.34, 2.84), P<0.001], long duration of disease [ OR (95% CI) =1.10(1.08, 1.13), P<0.001], smoking [ OR (95% CI) =2.47(1.57, 4.04), P<0.001], high disease activity [ OR (95% CI) =(1.21, 2.54), P=0.003), cough [ OR (95% CI) =6.10 (2.40, 15.52), P<0.001], decreased pulmonary carbon monoxide diffusing capacity [ OR (95% CI) =0.93(0.89, 0.96), P<0.001], and high titer anti-CCP antibody [ OR (95% CI) =1.14(1.03, 1.26), P=0.010], high titer RF [ OR (95% CI) =2.37(1.70, 3.29), P<0.001], high level of immunoglobulin A [ OR (95% CI) =1.26 (1.09, 1.46), P=0.002] and high level of glycoprotein antigen 125 [ OR (95% CI) =3.66 (1.81, 7.41), P<0.001]. Conclusion:The existing evidence have shown that advanced age, high age at onset, male, long disease duration, smoking, high disease activity, cough, decreased pulmonary carbon monoxide diffusing capacity, high titer anti-CCP antibody and RF, high level of immunoglobulin A and high level of glycoprotein antigen 125 are the main risk factors for interstitial lung disease in patients with rheumatoid arthritis. However, the evidence of Raynaud's phenomenon and tumor marker CA153 as risk factors for RA complicated with interstitial lung disease is not strong, and further high-quality prospective cohort studies are needed.
RESUMO
Objective To explore the temporal and spatial distribution characteristics of air pollutants PM2.5, PM10, SO2, CO, and NO2, and their effects on acute cerebrovascular diseases in Jining City. Methods The data of patients with acute cerebrovascular disease treated in a 3A hospital in Jining from October 1, 2017, to November 31, 2019, were retrospectively collected. Combined with the air pollution data of 29 air quality monitoring stations in Jining City, the Kriging interpolation model was used to analyze the overall situation of air pollution in Jining. On this basis, the relationship between air pollution and acute cerebrovascular diseases in Jining City was analyzed. Results In Jining City, the incidence of acute cerebrovascular disease in male was higher than that in female, and the incidence in rural areas was significantly higher than that in urban areas. The spatial distribution showed a trend of gradual accumulation from southeast to northwest. The daily average concentrations of PM2.5 and PM10 were higher in winter and spring than in summer and autumn. The results of Kriging interpolation analysis showed that the concentrations of these air pollutants formed aggregation points in varying degrees. The spatial distribution of acute cerebrovascular disease patients in Jining City was highly consistent with the spatial distribution of air pollutant concentrations. Spearman correlation analysis showed that CO, SO2, and NO2 were positively correlated with the incidence of acute cerebrovascular disease, while the correlation between PM2.5 and PM10 and the incidence of acute cerebrovascular disease was not significant. Conclusion Some air pollutants such as CO, SO2, and NO2 have a positive correlation with the incidence of acute cerebrovascular disease, and the prevalence has a certain population and regional distribution. In the future work of cerebrovascular disease prevention, personal protection should be done according to local conditions and living environment of specific people.
RESUMO
Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians′ heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.
RESUMO
The continuous glucose monitoring system (CGMS) has been clinically applied to monitor the dynamic change of the subcutaneous interstitial glucose concentration which is a function of the blood glucose level by glucose sensors. It can track blood glucose levels all day along, and thus provide comprehensive and reliable information about blood glucose dynamics. The clinical application of CGMS enables monitoring of blood glucose fluctuations and the discovery of hidden hyperglycemia and hypoglycemia that are difficult to be detected by traditional methods. As a CGMS needs to work subcutaneously for a long time, a series of factors such as biocompatibility, enzyme inactivation, oxygen deficiency, foreign body reaction, implant size, electrode flexibility, error correction, comfort, device toxicity, electrical safety, et al. should be considered beforehand. The study focused on the difficulties in the technology, and compared the products of Abbott, Medtronic and DexCom, then summarized their cutting-edge. Finally, this study expounded some key technologies in dynamic blood glucose monitoring and therefore can be utilized as a reference for the development of CGMS.

Objective:To describe the features of point-of-care cardiopulmonary ultrasound (POCUS) in the critically ill patients and analyze the independent factors associated with treatment changes after POCUS assessment.Methods:This was a prospective multicentric observational study from January to December 2018 in 13 intensive care units (ICU) in China. Consecutive patients admitted to the ICU were enrolled, POCUS were performed within the first 24 h of admission. The POCUS parameters included acute or chronic cardiac abnormality, diameter of inferior vena cava (IVC) at end-expiration, right ventricular systolic function, systolic and diastolic function of left ventricle (LV) and lung ultrasound score. The general features of patients and performers were recorded. Based on the treatment proposed by the performer before and after POCUS assessment, the patients were divided into treatment changed and unchanged groups. Factors associated with treatment changes were identified by multiple logistic regression analysis.Results:Totally 1 913 patients were enrolled including 322 (16.8%) patients with shock, 638 (33.3%) patients with respiratory failure, 139 (7.3%) patients with both shock and respiratory failure and 814 (42.6%) perioperative patients. POCUS had contributed to treatment changes in 1 204 (62.9%) patients, including 867 (72.0%) cases involved fluid management. Univariate analysis showed that there were significant differences in general characteristics of patients, performers and POCUS parameters between groups(all P<0.05). Logistic regression analysis showed that independent factors of treatment changes included ministry of education or university affiliated teaching hospitals (vs.general hospitals, OR=1.891, 95% CI=1.314-2.722, P<0.001 and OR=1.644, 95% CI=1.152-2.347, P=0.006 separately), middle and senior title performers (vs.primary title, OR=2.112, 95% CI=1.358-3.284, P=0.001, OR=3.271, 95% CI=2.129-5.025, P<0.001 separately), mechanical ventilation (vs.without, OR=0.488, 95% CI 0.381-0.626, P<0.001), IVC diameter ≤1 cm (vs.1-2 cm, OR=0.317, 95% CI 0.231-0.434, P<0.001), LV ejecting fraction <50% (vs.≥50%, OR=0.328, 95% CI=0.210-0.512, P<0.001), lung ultrasound score of 6-12 and >12 points(vs.score ≤ 6 points, OR=0.237, 95% CI=0.178-0.315, P<0.001 and OR=0.619, 95% CI=0.457-0.837, P=0.002 separately). Conclusions:POCUS assessment contributes to treatment changes, most of which involves fluid management strategy, in 62.9% critical patients. The independent influencing factors associated with POCUS parameters includes IVC diameter at end-expiratory, LV systolic function and lung ultrasound score. The performers′ title and hospital grade also have a noticeable effect.
RESUMO
Severe patients with coronaviras disease 2019 (COVID-19) are characterized by persistent lung damage, causing respiratory failure, secondary circulatory changes and multiple organ dysfunction after virus invasion. Because of its dynamic, real-time, non-invasive, repeatable and other advantages, critical ultrasonography can be widely used in the diagnosis, assessment and guidance of treatment for severe patients. Based on the recommendations of critical care experts from all over the country who fight against the epidemic in Wuhan, this article summarizes the guidelines for the treatment of COVID-19 based on critical ultrasonography, hoping to provide help for the treatment of severe patients. The recommendations mainly cover the following aspects: (1) lung ultrasound in patients with COVID-19 is mainly manifested by thickened and irregular pleural lines, different types of B-lines, shred signs, and other consolidation like dynamic air bronchogram; (2) Echocardiography may show right heart dysfunction, diffuse cardiac function enhancement, stress cardiomyopathy, diffuse cardiac depression and other multiple abnormalities; (3) Critical ultrasonography helps with initiating early treatment in the suspect patient, screening confirmed patients after intensive care unit admission, early assessment of sudden critical events, rapid grading assessment and treatment based on it; (4) Critical ultrasonography helps to quickly screen for the etiology of respiratory failure in patients with COVID-19, make oxygen therapeutic strategy, guide the implementation of lung protective ventilation, graded management and precise off-ventilator; (5) Critical ultrasonography is helpful for assessing the circulatory status of patients with COVID-19, finding chronic cardiopulmonary diseases and guiding extracorporeal membrane oxygenation management; (6) Critical ultrasonography contributes to the management of organs besides based on cardiopulmonary oxygen transport; (7) Critical ultrasonography can help to improve the success of operation; (8) Critical ultrasonography can help to improve the safety and quality of nursing; (9) When performing critical ultrasonography for patients with COVID-19, it needs to implement three-level protection standard, pay attention to disinfect the machine and strictly obey the rules from nosocomial infection. (10) Telemedicine and artificial intelligence centered on critical ultrasonography may help to improve the efficiency of treatment for the patients with COVID-19. In the face of the global spread of the epidemic, all we can do is to share experience, build a defense line, We hope this recommendations can help COVID-19 patients therapy.

RESUMO
Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients.However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. We have expanded and improved the application of traditional TEE and integrated the concept of critical care, established the concept of transesophageal echocardiography for critical care (TEECC). Chinese Critical Ultrasound Study Group (CCUSG) organized experts in the area to form the consensus based the previous studiesand the long term practice of critical care ultrasound and TEE, aiming at clarifying the nature and characteristics of TEECC, promoting the rational and standardized clinical application and the coming researches.The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.
RESUMO
At present, general practitioners in China lack both specialist knowledge and ability, which calls for close cooperation between general practitioners and specialists to better guarantee medical quality and patient safety. The authors reviewed the connotation, research status, development trend, problems and suggestions of general practitioners-specialists joint consultation service. Based on such, they pointed out that such a general practitioner-specialist joint clinic is quite new in the country, but numerous literature has confirmed that it can not only make up for services fragmentation, but also reduce referral rate.Furthermore, it can improve the quality of people′s lives, improve the general practitioner′s professional knowledge and skills, standardize general practitioner′s rational drug use. All these prove the reform an effective measure and deserves further promotion and greater supervision.

RESUMO
Objective To investigate the clinical significance of ultrasonography combined with scrological detection in the screening of trisomy 21.Methods The clinical data of 2 281 pregnant women who have received prenatal ultrasound examination,scrological detection and prenatal diagnosis in our hospital from January 2014 to March 2016 were retrospectively analyzed.All the fetuses had ultrasound abnormal or/and 21-trisomy syndrome high risk with scrological detection.The detection rate of trisomy 21 was observed when ultrasonography combined with scrological detection.The detection rate was compared between the two methods respectively.Results Among 2 281 pregnant women who received prenatal diagnosis,68 fetuses with trisomy 21 were diagnosed by fetal karyotype,the detection rate was 2.98% (68/2 281);There were 879 cases of merely ultrasound abnormal,27 of them were trisomy 21,the detection rate was 3.07% (27/879);1 336 cases were merely high risk of 21-trisomy syndrome,34 of them were trisomy 21,the detection rate was 2.54% (34/1 336);There were 66 cases of both ultrasound abnormal and 21-trisomy syndrome high risk,7 of them were trisomy 21,the detection rate was 10.61% (7/66).The method of joint use is higher than the independent method,with statistically significant difference (P < 0.05).Conclusions Ultrasonography combined with scrological detection have good application value in the screening of trisomy 21 syndrome.
RESUMO
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.
RESUMO
Objective To observe and explore the effects of different tidal volume (VT) ventilation on right ventricular (RV) function in patients with critical respiratory failure.Methods Consecutive respiratory failure patients who were treated with invasive ventilator over 24 h in the Department of Critical Care Medicine at the Fourth Hospital of Hebei Medical University from June to December in 2015 were enrolled in this study.Clinical data including patients′ vital signs, ventilator parameters and RV echocardiography were collected within 6 h (D0), day1(D1), day2 (D2) and day3 (D3) after ventilation started.According to the VT, patients with acute respiratory distress syndrome (ARDS) were assigned to low VT group [S6, ≤6 ml/kg predicted body weight (PBW)] and high VT group (L6, >6 ml/kg PBW), while non-ARDS patients were also assigned to low VT group (S8, ≤8 ml/kg PBW) and high VT group (L8, >8 ml/kg PBW).Results A total of 84 patients were enrolled in this study.44.2% ARDS patients and 58.5% non-ARDS patients were in low VT groups.After ventilation, tricuspid annulus plane systolic excursion(TAPSE)decreased progressively in S6 [from 18.30(16.70,20.70) mm to 17.55(15.70,19.50) mm, P=0.001], L6 [from 19.50(17.00,21.00) mm to 16.30(15.00,18.00) mm P=0.001], S8[from 18.00(16.00,21.00) mm to 16.50(15.50,18.00) mm, P=0.001] and L8 [from 19.00(17.50,21.50) mm to 16.35(15.15,17.00) mm, P=0.001] groups.However, TAPSE decreased less in small VT groups (S6 and S8) than those of in large VT groups (S8 and L8) without significant differences.There were not statistical differences between different VT groups in terms of ventilation days, including right ventricle area/left ventricle area (RVarea/LVarea),TAPSE,peak mitral flow velocity of the early rapid filling wave (E),peak mitral flow velocity of the late rapid filling wave (A),early diastolic velocity of the tricuspid annulus (e′),pulmonary artery systolic pressure,inferior vena cava diameter (all P>0.05).Compared to L6 group, low VT (S6 group) resulted in decreased mortality at 28 days [1/19 vs 37.5%(9/24), P=0.014].There were not statistical differences between different VT groups in terms of ventilation days, length of intensive care unit stay, length of hospital stay (all P>0.05).Logistic regression analysis showed that VT could be the independent factor of TAPSE (OR=1.104,95%CI 0.100-1.003,P=0.049).Conclusions Positive pressure mechanical ventilation resulted in RV systolic dysfunction.Lower VT may have the protective effect on RV function.Trial registration Chinese Clinical Trial Registry,ChiCTR-POC-15007563.
RESUMO
Objective To discuss the clinical application value of Omaha system-based targeting nursing care for patients with hepatocellular carcinoma (HCC) who were treated with transcatheter arterial chemoembolization (TACE).Methods A total of 60 advanced HCC patients,who were planned to receive TACE,were prospectively and randomly divided into the control group (n=30) and the observation group (n=30).Routine nursing mode was adopted for the patients in the control group,while Omaha system nursing model was employed for the patients in the observation group.The patients of the observation group were evaluated with Omaha system at the time of admission,the key common problems were screened out and targeted nursing measures were employed.Meanwhile,on the days of admission and discharge all the patients of both groups were asked to fill in the forms of Hamilton depression scale (HAMD-17),Hamilton anxiety scale (HAMA),social support rating scale (SSQ) and numerical pain rating scale (NRS);and the degrees of depression,anxiety,social support and pain were respectively assessed.Results Both nursing modes could improve the degrees of depression and anxiety as well as the social support system of HCC patients,but the curative effect of these two aspects in the observation group were obviously better than those in the control group (P<0.05).No statistically significant difference in the improvement of pain degree existed between the two nursing models,but Omaha system-based targeting nursing mode could alleviate the patient's pain to a certain extent.Conclusion For patients with advanced HCC,Omaha system-based targeting nursing care can alleviate the patient's negative emotion and promote the patients to establish effective social support system,this nursing mode is superior to conventional nursing mode.Therefore,Omaha system-based targeting nursing has great application potential in clinical practice.

Objective To discuss the efficacy and safety of transversus abdominis plane block (TAPB) combined with rectus sheath block (RSB) for peritoneal dialysis catheter placement.Methods Thirty patients,ASA Ⅰ or Ⅱ,body mass index (BMI) 18-30 kg/m2,were scheduled for elective peritoneal dialysis catheter placement.They were randomly divided into three groups:local anesthesia group (group L),ultrasound-guided TAPB group (group T),ultrasound-guided TAPB combined with RSB group (group TR).Mean arterial blood pressure (MAP) and heart rate (HR) were recorded before (T0) and after (T1) anaesthesia,the beginning of operation (T2) and abdomen-closing (T3),6 h (T4),12 h (T5),24 h (T6) after surgery.The consumption of local anesthetic during the surgery,dezocine after the surgery,the score of visual analogue scale (VAS) during rest and movement at T2-T6 and the adverse reactions were recorded.Results At T3,MAP and HR in group L and group T were higher than those in group TR (P < 0.05).At T4 and T5,MAP and HR in group L were higher than those in group T and group TR (P < 0.05);the consumption of local anesthetic ropivacaine in group L and group T were more than that in group TR (P < 0.05);the consumption of local anesthetic ropivacaine and dezocine in group L were more than that in group T (P < 0.05).The VAS score was significantly lower in group T and group TR at T3,T4,T5 compared with that in group L (P < 0.05).There were no adverse reactions.Conclusion Ultrasound-guided TAPB combined with RSB is safe and efficacious in patients undergoing peritoneal dialysis catheter placement.

RESUMO
Objective To evaluate the excursion of the diaphragm and analyze the value in predicting weaning from mechanical ventilation in intensive care unit patients.Methods The patients with mechanical ventilation (>48 hours) in ICU at Hebei Forth Medical University Hospital from June 2014 to December were classified into a success group or a failure group according to the weaning outcome.T-piece spontaneous breathing (SBT),airway occlusion pressure at 0.1 sec (P0.1) and maximal inspiratory pressure (MIP),rapid shallow breathing index (RSBI) and P0.1/MIP were measured or calculated.During the period of the 1 st hour SBT,the excursion of diaphragm was measured with ultrasonography.The predictive value of each parameter to weaning was evaluated with ROC curve.Results A total of 98 patients were enrolled in this study,including 74 successfully weaning and 24 failed.There were significant differences between two groups (success group and failure group) in P0.1 [(2.00 ± 2.00) cmH2O (1 cmH2O =0.098 kPa) vs (3.00 ±2.75)cmH2O,P <0.05],RSBI (39.14 ± 16.81 vs 52.00 ± 19.18,P <0.05),left diaphragmatic excursion [(1.12 ± 0.97) cm vs (0.69 ± 1.00) cm,P < 0.001],right diaphragmatic excursion(1.87 ± 0.75) cm vs (1.17 ± 0.76) cm,P < 0.001] and mean value of left and right diaphragmatic excursion [(1.57 ± 0.52) cm vs (0.83 ± 0.53) cm,and P < 0.001].The ventilation time [2.00 (2.00-4.00) d vs 4.00 (2.00-5.00) d],ICU hospital lengths of stay [4.50 (3.00-7.25) d vs 8.50 (6.25-15.25) d] and total hospital lengths of stay [20.00 (15.00-25.25) d vs 25.00 (20.25-37.25)d] were also statistically significant in success group and failure group respectively (all P < 0.05).The cutoff value of diaphragmatic excursion for predicting successful extubation was determined to be 1.14 cm by ROC curve analysis.The sensitivity of diaphragmatic excursion to predict successful weaning was 89.2% and the specificity was 75.0%,the AUCROC was 0.849.Conclusion As an early predictor of diaphragmatic dysfunction,diaphragmatic excursion is probably superior to the traditional parameters in predicting weaning from ventilator in ICU patients.
