Objective:Some pregnancy complications are associated with respiratory problems in infants.Early identification and implementation of respiratory support are needed for these infants.This study aimed to(1)use lung ultrasound(LU)for predicting the respiratory support requirements of infants and(2)simplify the examination method to facilitate its clinical application.Methods:Neonates underwent LU examinations within 1 hour of birth.The infants were divided into a pregnancy complication(PC)group and a control group according to their mothers'clinical data.The primary outcome measure was the need for respiratory support.Predictive models were established based on the differences in LU patterns between the two groups.The predictive value of the models was compared with that of the LU score(LUS)system,which has been widely used in other studies.Simplified models were established by analyzing the predictive effects of LU patterns in different parts of the lungs.Predictive reliability was tested using the receiver operating characteristic curve analysis.Results:PC and control groups had 29 and 117 neonates,respectively;a total of 22 neonates required respiratory support.The PC and control groups showed differences in respiratory support requirements,A-lines,and coalesced B-lines.The percentages of A-lines and coalesced B-lines were associated with respiratory support requirements.The optimal cutoff values for the percentages of the A-lines and coalesced B-lines were 55.7%and 24.5%,respectively.Similar effects were obtained by calculating the percentage of coalesced B-lines in four areas(R3,R4,L3,and L4).These methods were judged as more visual and convenient than LUS assessment.conclusion:The percentages of A-line and coalesced B-lines on LU images can be used to predict the respiratory support needs of neonates whose mothers had pregnancy complications.Only four areas(R3,R4,L3,and L4)had similar predictive values. 展开更多

Severe acute respiratory syndrome (SARS) is an acute respiratory illness caused by infection with the SARS virus. The most obvious clinical characteristic of SARS is rapidly progressive pneumonia, and about 20% patients need intensive care due to acute lung injury (ALI) and acute respiratory distress syndrome (ARDS).1-3 In the absence of effective drugs for SARS, supportive care, especially respiratory support techniques (RSTs), is of primary importance. On the other hand, offering RSTs to SARS patients may carry a high-risk of infection to healthcare workers because of the high infectivity of SARS. Therefore, the strategy of RSTs for SARS should be the integration of efficacy and safety. In this issue of the Chinese Medical Journal, an article from Hong Kong has retrospectively compared both the safety and efficacy of noninvasive positive pressure ventilation (NIPPV) with that of invasive mechanical ventilation (IMV) in the treatment of respiratory failure in SARS. 展开更多

Background:The coronavirus disease 2019(COVID-19)is an ongoing pandemic.Invasive mechanical ventilation(IMV)is essential for the management of COVID-19 with acute respiratory distress syndrome(ARDS).We aimed to assess the impact of compliance with a respiratory decision support system on the outcomes of patients with COVID-19-associated ARDS who required IMV.Methods:In this retrospective,single-center,case series study,patients with COVID-19-associated ARDS who required IMV at Zhongnan Hospital of Wuhan University,China,from January 8th,2020,to March 24th,2020,with the final follow-up date of April 20th,2020,were included.Demographic,clinical,laboratory,imaging,and management information were collected and analyzed.Compliance with the respiratory support decision system was documented,and its relationship with 28-day mortality was evaluated.Results:The study included 46 COVID-19-associated ARDS patients who required IMV.The median age of the 46 patients was 68.5 years,and 31 were men.The partial pressure of arterial oxygen(PaO_(2))/fraction of inspired oxygen(FiO_(2))ratio at intensive care unit(ICU)admission was 104 mmHg.The median total length of IMV was 12.0(interquartile range[IQR]:6.0–27.3)days,and the median respiratory support decision score was 11.0(IQR:7.8–16.0).To 28 days after ICU admission,18(39.1%)patients died.Survivors had a significantly higher respiratory support decision score than non-survivors(15.0[10.3–17.0]vs.8.5(6.0–10.3),P=0.001).Using receiver operating characteristic(ROC)curve to assess the discrimination of respiratory support decision score to 28-day mortality,the area under the curve(AUC)was 0.796(95%confidence interval[CI]:0.657–0.934,P=0.001)and the cut-offwas 11.5(sensitivity=0.679,specificity=0.889).Patients with a higher score(>11.5)were more likely to survive at 28 days after ICU admission(log-rank test,P<0.001).Conclusions:For severe COVID-19-associated ARDS with IMV,following the respiratory support decision and assessing completion would improve the progress of ventilation.With a decision score of>11.5,the mortality at 28 days after ICU admission showed an obvious decrease. 展开更多

Coronavirus disease 2019 is a pandemic,was first recognized at Wuhan province,China in December 2019.The disease spread quickly across the globe,spreading stealthily from human to human through both symptomatic and asymptomatic individuals.A multisystem disease which appears to primarily spread via bio aerosols,it has exhibited a wide clinical spectrum involving multiple organ systems with the respiratory system pathology being the prime cause of morbidity and mortality.Initially unleashing a huge destructive trail at Wuhan China,Lombardy Italy and New York City,it has now spread to all parts of the globe and has actively thrived and mutated into new forms.Health care systems and Governments responded initially with panic,with containment measures giving way to mitigation strategies.The global medical and scientific community has come together and responded to this huge challenge.Professional medical societies quickly laid out“expert”guidelines which were conservative in their approach.Many drugs were re formulated and tested quickly with the help of national and international collaborative groups,helping carve out effective treatment strategies and help build a good scientific foundation for evidencebased medicine.Out of the darkness of chaos,we now have an orderly approach to manage this disease both from a public health preventive and therapeutic standpoint.With preventive measures such as masking and social distancing to the development of highly effective and potent vaccines,the public health success of such measures has been tempered by behavioral responses and resource mobilization.From a therapy standpoint,we now have drugs that were promising but now proven ineffective,and those that are effective when given early during viral pathogenesis or later when immune dysregulation has established,and the goal is to help reign in the destructive cascade.It has been a fascinating journey for mankind and our work here recapitulates the evolution of various aspects of critical care and other inpatient practices which continue to evolve. 展开更多

Background Since the beginning of the coronavirus disease 2019(COVID-19)pandemic,prone positioning has been widely applied for non-intubated,spontaneously breathing patients.However,the efficacy and safety of prone positioning in non-intubated patients with COVID-19-related acute hypoxemic respiratory failure remain unclear.We aimed to systematically analyze the outcomes associated with awake prone positioning(APP).Methods We conducted a systematic literature search of PubMed/MEDLINE,Cochrane Library,Embase,and Web of Science from January 1,2020,to June 3,2022.This study included adult patients with acute respiratory failure caused by COVID-19.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines were followed,and the study quality was assessed using the Cochrane risk-of-bias tool.The primary outcome was the reported cumulative intubation risk across randomized controlled trials(RCTs),and the effect estimates were calculated as risk ratios(RRs;95%confidence interval[CI]).Results A total of 495 studies were identified,of which 10 fulfilled the selection criteria,and 2294 patients were included.In comparison to supine positioning,APP significantly reduced the need for intubation in the overall population(RR=0.84,95%CI:0.74–0.95).The two groups showed no significant differences in the incidence of adverse events(RR=1.16,95%CI:0.48–2.76).The meta-analysis revealed no difference in mortality between the groups(RR=0.93,95%CI:0.77–1.11).Conclusions APP was safe and reduced the need for intubation in patients with respiratory failure associated with COVID-19.However,it did not significantly reduce mortality in comparison to usual care without prone positioning. 展开更多

Background Congenital heart disease(CHD)is one of the main supportive diseases of extracorporeal membrane oxygena-tion in children.The management of extracorporeal membrane oxygenation(ECMO)for pediatric CHD faces more severe challenges due to the complex anatomical structure of the heart,special pathophysiology,perioperative complications and various concomitant malformations.The survival rate of ECMO for CHD was significantly lower than other classifica-tions of diseases according to the Extracorporeal Life Support Organization database.This expert consensus aims to improve the survival rate and reduce the morbidity of this patient population by standardizing the clinical strategy.Methods The editing group of this consensus gathered 11 well-known experts in pediatric cardiac surgery and ECMO field in China to develop clinical recommendations formulated on the basis of existing evidences and expert opinions.Results The primary concern of ECMO management in the perioperative period of CHD are patient selection,cannulation strategy,pump flow/ventilator parameters/vasoactive drug dosage setting,anticoagulation management,residual lesion screening,fluid and wound management and weaning or transition strategy.Prevention and treatment of complications of bleeding,thromboembolism and brain injury are emphatically discussed here.Special conditions of ECMO management related to the cardiovascular anatomy,haemodynamics and the surgical procedures of common complex CHD should be considered.Conclusions The consensus could provide a reference for patient selection,management and risk identification of periop-erative ECMO in children with CHD. 展开更多
