Comparison of Respiratory Support After Delivery in Infants Born Before 28 Weeks' Gestational Age: The CORSAD Randomized Clinical Trial.

Importance: Establishing stable breathing is a key event for preterm infants after birth. Delivery of pressure-stable continuous positive airway pressure and avoiding face mask use could be of importance in the delivery room. Objective: To determine whether using a new respiratory support system with low imposed work of breathing and short binasal prongs decreases delivery room intubations or death compared with a standard T-piece system with a face mask. Design, Setting, and Participants: In this unblinded randomized clinical trial, mothers threatening preterm delivery before week 28 of gestation were screened. A total of 365 mothers were enrolled, and 250 infants were randomized before birth and 246 liveborn infants were treated. The trial was conducted in 7 neonatal intensive care units in 5 European countries from March 2016 to May 2020. The follow-up period was 72 hours after intervention. Interventions: Infants were randomized to either the new respiratory support system with short binasal prongs (n = 124 infants) or the standard T-piece system with face mask (n = 122 infants). The intervention was providing continuous positive airway pressure for 10 to 30 minutes and positive pressure ventilation, if needed, with the randomized system. Main Outcomes and Measures: The primary outcome was delivery room intubation or death within 30 minutes of birth. Secondary outcomes included respiratory and safety variables. Results: Of 246 liveborn infants treated, the mean (SD) gestational age was 25.9 (1.3) weeks, and 127 (51.6%) were female. A total of 41 infants (33.1%) receiving the new respiratory support system were intubated or died in the delivery room compared with 55 infants (45.1%) receiving standard care. The adjusted odds ratio was statistically significant after adjusting for stratification variables (adjusted odds ratio, 0.53; 95% CI, 0.30-0.94; P = .03). No significant differences were seen in secondary outcomes or safety variables. Conclusions and Relevance: In this study, using the new respiratory support system reduced delivery room intubation in extremely preterm infants. Stabilizing preterm infants with a system that has low imposed work of breathing and binasal prongs as interface is safe and feasible. Trial Registration: ClinicalTrials.gov Identifier: NCT02563717.

Effects of three pulmonary ventilation regimes in patients undergoing coronary artery bypass graft surgery: a randomized clinical trial.

The aim was to compare the effect of diaphragmatic breathing exercise (DBE), flow- (FIS) and volume-oriented incentive spirometry (VIS) on pulmonary function- (PFT), functional capacity-6-Minute Walk Test (6 MWT) and Functional Difficulties Questionnaire (FDQ) in subjects undergoing Coronary Artery Bypass Graft surgery (CABG). The purpose of incorporating pulmonary ventilator regimes is to improve ventilation and avoid post-operative pulmonary complications. CABG patients (n = 72) were allocated to FIS, VIS and DBE groups (n = 24 each) by block randomization. Preoperative and postoperative values for PFT were taken until day 7 for all three groups. On 7th postoperative day, 6 MWT and FDQ was analyzed using ANOVA and post-hoc analysis. PFT values were found to be decreased on postoperative day 1(Forced Vital Capacity (FVC) = FIS group-65%, VIS group-47%, DBE group-68%) compared to preoperative day (p < 0.001). PFT values for all 3 groups recovered until postoperative day 7 (FVC = FIS group-67%, VIS group-95%, DBE group-59%) but was found to reach the baseline in VIS group (p < 0.001). When compared between 3 groups, statistically significant improvement was observed in VIS group (p < 0.001) in 6 MWT and FDQ assessment. In conclusion, VIS was proven to be more beneficial in improving the pulmonary function (FVC), functional capacity and FDQ when compared to FIS and DBE.

[Inhaled therapies in COPD - all patients on fixed triple?] / Inhalative Therapie der COPD ­ alle Patienten auf "fixed triple"?

Inhaled maintenance therapies in chronic obstructive pulmonary disease (COPD) are based on bronchodilators and inhaled corticosteroids (ICS). Inhaled bronchodilator therapies consist of long-acting beta-2 agonists (LABA) and long-acting muscarinic antagonists (LAMA). LABA or LAMA treatment is recommended in symptomatic COPD patients. In case of a history of exacerbations LAMA is superior to LABA in the prevention of exacerbations. LABA LAMA combination therapies are used in patients who are highly symptomatic. Adding ICS to bronchodilator treatment is recommended in COPD patients with repeated exacerbations. Recently, fixed triple therapies consisting of LABA, LAMA and ICS in single inhalers became available.

Respiratory and pharmacological management in severe acute bronchiolitis: Were clinical guidelines not written for critical care?

PURPOSE: The treatment applied for children admitted to the pediatric intensive care unit (PICU) for severe acute bronchiolitis may differ from general recommendations. The first objective of our study was to describe the treatments offered to these children in a Spanish tertiary PICU. The second objective was to analyse the changes in management derived from the publication of the American Academy of Pediatrics (AAP) bronchiolitis guideline in 2014. METHODS: This was a retrospective-prospective observational study conducted during two epidemic waves (2014-2015 and 2015-2016). The AAP guidelines were distributed and taught to PICU staff between both epidemic waves. RESULTS: A total of 138 children were enrolled (78 male). In the first period, 78 children were enrolled. The median age was 1.8 months (IQR 1.1-3.6). There were no differences between the management in the two periods, except for the use of high-flow oxygen therapy (HFOT); its use increased in the second period. Overall, 83% of patients received non-invasive ventilation or HFOT. Children older than 12 months received HFOT exclusively. In comparison, continuous positive airway pressure and bi-level positive airway pressure were used less during the period 2015-2016 (P=0.036). Regarding pharmacological therapy, 70% of patients received antibiotics, 23% steroids, 33% salbutamol, 31% adrenaline, and 7% hypertonic saline. The mortality rate was zero. CONCLUSIONS: Our PICU did not follow the AAP recommendations. There were no differences between the two periods, except in the use of HFOT. All children older than 12 months received HFOT exclusively. The rate of using invasive mechanical ventilation was also low.

[Recommendations from the German Respiratory Society for Pulmonary Rehabilitation in Patients with COVID-19]. / DGP-Empfehlungen zur pneumologischen Rehabilitation bei COVID-19.

The German Respiratory Society (DGP) has commissioned Assembly 12 "Rehabilitation, Prevention and Tobacco Control" to develop recommendations for the implementation of pulmonary rehabilitation in COVID-19 patients. This position paper is based on the current state of knowledge, which develops daily. This position paper describes the health consequences in COVID-19 as well as the indications for pulmonary rehabilitation. Rehabilitative therapies in COVID-19 are already indicated on the ward or intensive care unit, continue as early pulmonary rehabilitation in the acute hospital and as pulmonary rehabilitation in pulmonary rehabilitation centers. The main focus of this position paper is to propose recommendations for the content-related implementation of a multimodal, interdisciplinary pulmonary rehabilitation in COVID-19 patients.

Coronavirus disease 2019 (COVID-19) in Brasil: information to physical therapists.

The emergence of the Coronavirus Disease 2019 (COVID-19) pandemic shows a rapid increase in cases and deaths. The World Health Organization (WHO) has shown that more than 200.000 confirmed cases have been identified in more than 166 countries/territories. Public health authorities in Brasil have reported 532 confirmed cases by March 19. Approximately 5% of the patients will require intensive care unit treatment with oxygen therapy and mechanical ventilation. Limited data are available about rehabilitation protocols for severe illness and intensive care treatment of COVID-19 increase. Thus, we aim to show current information about COVID-19, describing symptoms and the respiratory management for critical patients and preventive care. Physical therapists and all health care professionals need to recognize the challenges they will face in the coming months.

Improving the use of the 'COUGH' bundle in Surgical High Dependency Unit, Ninewells Hospital, Dundee.

Developing respiratory complications postoperatively is one of the major determinants of longer hospital stay, morbidity, mortality and increased healthcare costs. The incidence of postoperative respiratory complications varies from 1% to 23%. Given that postoperative respiratory complications are relatively common and costly, there have been various studies which look at ways to reduce the risk of these occurring. One such protocol is the ICOUGH bundle which stands for Incentive spirometry, Coughing and deep breathing, Oral care, patient Understanding, Getting out of bed and Head of bed elevation. This has been adapted locally to the Coughing and deep breathing, Oral care, patient Understanding, Getting out of bed and Head of bed elevation (COUGH) bundle which consists of these components excluding incentive spirometry. Within our surgical high dependency unit (HDU), the COUGH bundle should be implemented in patients who have a moderate or high risk of developing postoperative respiratory complications with an Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score of 26 or above. Studies have shown that the ICOUGH bundle has reduced rates of pneumonia and unplanned intubation in general surgical and vascular patients. Baseline data taken from surgical HDU showed that the COUGH bundle was not well implemented. One out of eight patients who had an ARISCAT score greater than 26 had the COUGH bundle implemented on admission to the unit. Three out of eight patients had the ARISCAT score documented in their admission medical review. One patient who should have received the bundle, but did not, developed a hospital acquired pneumonia postoperatively. To address this issue, we aimed to increase awareness surrounding the COUGH bundle and to increase the number of patients who had the COUGH bundle started on admission. This quality improvement project had four cycles (plan, do, study, act) and after these, 100% of patients who had an ARISCAT score of 26 or more had the COUGH bundle implemented.

"We're Not Ready, But I Don't Think You're Ever Ready." Clinician Perspectives on Implementation of Crisis Standards of Care.

Background: The COVID-19 pandemic has highlighted health care systems' vulnerabilities. Hospitals face increasing risk of periods of scarcity of life-sustaining resources such as ventilators for mechanical respiratory support, as has been the case in Italy as of March, 2020. The National Academy of Medicine has provided guidance on crisis standards of care, which call for the reallocation of scarce medical resources to those who will benefit most during extreme situations. Given that this will require a departure from the usual fiduciary duty of the bedside clinician, we determined and mapped potential barriers to the implementation of the guidelines from stakeholders using an implementation science framework. Methods: A protocol was created to operationalize national and state guidelines for triaging ventilators during crisis conditions. Focus groups and key informant interviews were conducted from July-September 2018 with clinicians at three acute care hospitals of an urban academic medical center. Respiratory therapists, intensivists, nursing leadership and the palliative care interdisciplinary team participated in focus groups. Key informant interviews were conducted with emergency management, respiratory therapy and emergency medicine. Subjects were presented the protocol and their reflections were elicited using a semi-structured interview guide. Data from transcripts and notes were categorized using a coding strategy based on the Theoretical Domains Framework. Results: Participants anticipated that implementing this protocol would challenge their roles and identities as clinicians including both their fiduciary duty to the patient and their decision-making autonomy. Despite this, many participants acknowledged the need for such a protocol to standardize care and minimize bias as well as to mitigate potential consequences for individual clinicians. Participants identified the question of considering patient quality of life in triage decisions as an important and unresolved ethical issue in disaster triage. Conclusion: Clinicians' discomfort with shifting roles and obligations could pose implementation barriers for crisis standards of care.

[Guide for follow-up of patients with SARS-CoV-2 pneumonia. Management proposals developed by the French-language Respiratory Medicine Society. Version of 10 May 2020]. / Guide pour le suivi respiratoire des patients ayant présenté une pneumonie à SARS-CoV-2. Propositions de prise en charge élaborées par la Société de pneumologie de langue française. Version du 10 mai 2020.

The French-language Respiratory Medicine Society (SPLF) proposes a guide for the follow-up of patients who have presented with SARS-CoV-2 pneumonia. The proposals are based on known data from previous epidemics, on acute lesions observed in SARS-CoV-2 patients and on expert opinion. This guide proposes a follow-up based on three categories of patients: (1) patients managed outside hospital for possible or proven SARS-CoV-2 infection, referred by their physician for persistent dyspnoea; (2) patients hospitalized for SARS-CoV-2 pneumonia in a medical unit; (3) patients hospitalized for SARS-CoV-2 pneumonia in an intensive care unit. The subsequent follow-up will have to be adapted to the initial assessment. This guide emphasises the possibility of others causes of dyspnoea (cardiac, thromboembolic, hyperventilation syndrome…). These proposals may evolve over time as more knowledge becomes available.

[Expert consensus on preventing nosocomial transmission during respiratory care for critically ill patients infected by 2019 novel coronavirus pneumonia].

Definite evidence has shown that the novel coronavirus (COVID-19) could be transmitted from person to person, so far more than 1 700 bedside clinicians have been infected. A lot of respiratory treatments for critically ill patients are deemed as high-risk factors for nosocomial transmission, such as intubation, manual ventilation by resuscitator, noninvasive ventilation, high-flow nasal cannula, bronchoscopy examination, suction and patient transportation, etc, due to its high possibility to cause or worsen the spread of the virus. As such, we developed this consensus recommendations on all those high-risk treatments, based on the current evidence as well as the resource limitation in some areas, with the aim to reduce the nosocomial transmission and optimize the treatment for the COVID-19 pneumonia patients. Those recommendations include: (1)Standard prevention and protection, and patient isolation; (2)Patient wearing mask during HFNC treatment; (3)Using dual limb ventilator with filters placed at the ventilator outlets, or using heat-moisture exchanger (HME) instead of heated humidification in single limb ventilator with HME placed between exhalation port and mask; avoid using mask with exhalation port on the mask; (4)Placing filter between resuscitator and mask or artificial airway; (5)For spontaneous breathing patients, placing mask for patients during bronchoscopy examination; for patients receiving noninvasive ventilation, using the special mask with bronchoscopy port to perform bronchoscopy; (6)Using sedation and paralytics during intubation, cuff pressure should be maintained between 25-30 cmH(2)O(1 cmH(2)O=0.098 kPa); (7)In-line suction catheter is recommended and it can be used for one week; (8)Dual-limb heated wire circuits are recommended and only changed with visible soiled; (9)For patients who need breathing support during transportation, placing an HME between ventilator and patient; (10)PSV is recommended for implementing spontaneous breathing trial (SBT), avoid using T-piece to do SBT. When tracheotomy patients are weaned from ventilator, HME should be used, avoid using T-piece or tracheostomy mask. (11)Avoid unnecessary bronchial hygiene therapy; (12) For patients who need aerosol therapy, dry powder inhaler metered dose inhaler with spacer is recommended for spontaneous breathing patients; while vibrating mesh nebulizer is recommended for ventilated patients and additional filter is recommended to be placed at the expiratory port of ventilation during nebulization.

[Recommendations for respiratory rehabilitation of coronavirus disease 2019 in adult].

COVID-19 is a highly infectious respiratory infection disease, which leads to dysfunction of respiratory, physical, and psychological of the patients. pulmonary rehabilitation is an important intervention for clinical patients as well as cure patients. With the deeper cognition of COVID-19 and accumulation of clinical experience, we proposed the recommendations for pulmonary rehabilitation of COVID-19 in adults based on the opinions of front-line clinical experts involved in the management of this epidemic and a review of the relevant literature and evidences: (1)for the inpatients with COVID-19, pulmonary rehabilitation would relieve the symptoms of dyspnea, anxiety, and depression; eventually improve physical function and the quality of life; (2)For severe/critical inpatients, the early performance of pulmonary rehabilitation is not suggested. (3)For isolating patients, the pulmonary rehabilitation guidence should be conducted through education video, instruction manual or remote consultation. (4)Assessment and monitor should be performed throughout the entire pulmonary rehabilitation process.(5)Taking proper grading protection following the guideline. These recommendations can serve as a clinical practice guidence and basis for pulmonary rehabilitation of COVID-19.

Respiratory physiotherapy in patients with COVID-19 infection in acute setting: a Position Paper of the Italian Association of Respiratory Physiotherapists (ARIR).

Respiratory physiotherapy in patients with COVID-19 infection in acute setting: a Position Paper of the Italian Association of Respiratory Physiotherapists (ARIR) On February 2020, Italy, especially the northern regions, was hit by an epidemic of the new SARS-Cov-2 coronavirus that spread from China between December 2019 and January 2020. The entire healthcare system had to respond promptly in a very short time to an exponential growth of the number of subjects affected by COVID-19 (Coronavirus disease 2019) with the need of semi-intensive and intensive care units.

E-Cigarette or Vaping Product Use-associated Lung Injury: Developing a Research Agenda. An NIH Workshop Report.

The NHLBI convened a working group on October 23, 2019, to identify the most relevant and urgent research priorities and prevailing challenges in e-cigarette or vaping product use-associated lung injury (EVALI). Experts across multiple disciplines discussed the complexities of the EVALI outbreak, identified research priorities, and recommended strategies to address most effectively its causal factors and improve diagnosis, treatment, and prevention of this disease. Many research priorities were identified, including the need to create national and international registries of patients with EVALI, to track accurately those affected and assess outcomes. The group concluded that biospecimens from subjects with EVALI are urgently needed to help define EVALI pathogenesis and that vaping has disease risks that are disparate from smoking, with the occurrence of EVALI highlighting the importance of broadening e-cigarette research beyond comparators to smoking-related diseases.

Improved Outcomes With Standardized Convalescent Preterm Respiratory Care Practices.

BACKGROUND: Chronic lung disease is the most common morbidity affecting very low birthweight (VLBW) infants. Many of these infants are discharged home on oxygen, placing significant emotional and financial burdens on families. We sought to reduce the proportion of VLBW infants requiring discharge home on oxygen by improving convalescent respiratory practices. METHODS: We performed a prospective quality-improvement project for infants with birth weights ≤ 1,500 g in a single neonatal ICU. Using Plan-Do-Study-Act cycles, we developed and implemented a room air challenge, oxygen reference chart, and a standardized oxygen delivery guideline. The primary outcome was the proportion of VLBW infants discharged home on oxygen. Secondary outcomes included rate of chronic lung disease and postmenstrual age when off all respiratory support. Balancing measures were postmenstrual age and weight at discharge, as well as unplanned readmissions. Statistical process control charts were used to monitor outcomes and balancing measures. RESULTS: The proportion of VLBW infants discharged home on oxygen decreased from 34.4% to 18.5% and 21.7% in the following two years (P = .044 and P = .01, respectively). G-Chart analysis showed a higher mean number of successes between failures. The rate of chronic lung disease decreased from 31.2% to 25.4% (P = .03). The mean postmenstrual age at discharge, mean weight at discharge, and readmission rate were unchanged. CONCLUSION: Standardization of convalescent respiratory care practices improved respiratory morbidities in VLBW infants. These interventions could be utilized in other NICUs with high incidence of respiratory morbidities despite improvement in delivery room practices.
