Abstract Background Noninvasive positive pressure ventilation (NIPPV) has been increasingly used in the management of respiratory failure in intensive care unit (ICU). Aim of the Work is to compare the efficacy and resource consumption of NIPPMV delivered through face mask against invasive mechanical ventilation (IMV) delivered by endotracheal tube in the management of patients with acute respiratory failure (ARF). Patients and Methods This prospective randomized controlled study included 78 adults with acute respiratory failure who were admitted to the intensive care unit. The enrolled patients were randomly allocated to receive either noninvasive ventilation or conventional mechanical ventilation (CMV). Results Severity of illness, measured by the simplified acute physiologic score 3 (SAPS 3), were comparable between the two patient groups with no significant difference between them. Both study groups showed a comparable steady improvement in PaO2:FiO2 values, indicating that NIPPV is as effective as CMV in improving the oxygenation of patients with ARF. The PaCO2 and pH values gradually improved in both groups during the 48 hours of ventilation. 12 hours after ventilation, NIPPMV group showed significantly more improvement in PaCO2 and pH than the CMV group. The respiratory acidosis was corrected in the NIPPV group after 24 hours of ventilation compared with 36 hours in the CMV group. NIPPV in this study was associated with a lower frequency of complications than CMV, including ventilator acquired pneumonia (VAP), sepsis, renal failure, pulmonary embolism, and pancreatitis. However, only VAP showed a statistically significant difference. Patients who underwent NIPPV in this study had lower mortality, and lower ventilation time and length of ICU stay, compared with patients on CMV. Intubation was required for less than a third of patients who initially underwent NIV. Conclusion Based on our study findings, NIPPV appears to be a potentially effective and safe therapeutic modality for managing patients with ARF.

Research Questions

Background Acute respiratory failure is generally treated with invasive mechanical ventilation or noninvasive respiratory support strategies. The efficacies of the various strategies are not fully understood. There is a need for accurate therapy-based phenotyping for secondary analyses of electronic health record data to answer research questions regarding respiratory management and outcomes with each strategy. Objective The objective of this study was to address knowledge gaps related to ventilation therapy strategies across diverse patient populations by developing an algorithm for accurate identification of patients with acute respiratory failure. To accomplish this objective, our goal was to develop rule-based computable phenotypes for patients with acute respiratory failure using remotely monitored intensive care unit (tele-ICU) data. This approach permits analyses by ventilation strategy across broad patient populations of interest with the ability to sub-phenotype as research questions require. Methods Tele-ICU data from ≥200 hospitals were used to create a rule-based algorithm for phenotyping patients with acute respiratory failure, defined as an adult patient requiring invasive mechanical ventilation or a noninvasive strategy. The dataset spans a wide range of hospitals and ICU types across all US regions. Structured clinical data, including ventilation therapy start and stop times, medication records, and nurse and respiratory therapy charts, were used to define clinical phenotypes. All adult patients of any diagnoses with record of ventilation therapy were included. Patients were categorized by ventilation type, and analysis of event sequences using record timestamps defined each phenotype. Manual validation was performed on 5% of patients in each phenotype. Results We developed 7 phenotypes: (0) invasive mechanical ventilation, (1) noninvasive positive-pressure ventilation, (2) high-flow nasal insufflation, (3) noninvasive positive-pressure ventilation subsequently requiring intubation, (4) high-flow nasal insufflation subsequently requiring intubation, (5) invasive mechanical ventilation with extubation to noninvasive positive-pressure ventilation, and (6) invasive mechanical ventilation with extubation to high-flow nasal insufflation. A total of 27,734 patients met our phenotype criteria and were categorized into these ventilation subgroups. Manual validation of a random selection of 5% of records from each phenotype resulted in a total accuracy of 88% and a precision and recall of 0.8789 and 0.8785, respectively, across all phenotypes. Individual phenotype validation showed that the algorithm categorizes patients particularly well but has challenges with patients that require ≥2 management strategies. Conclusions Our proposed computable phenotyping algorithm for patients with acute respiratory failure effectively identifies patients for therapy-focused research regardless of admission diagnosis or comorbidities and allows for management strategy comparisons across populations of interest.

Chronic Respiratory Insufficiency

Noninvasive ventilation has been used extensively to treat chronic respiratory failure associated with neuromuscular and other restrictive thoracic diseases, and is also effective in the treatment of acute respiratory failure, allowing some patients to avoid intubation. Noninvasive positive pressure ventilation is a potentially effective way to transition selected patients off endotracheal mechanical ventilation. The authors present a retrospective chart review of pediatric patients extubated with the use of noninvasive ventilation. Extubation with noninvasive positive pressure ventilation was attempted in 25 patients. The patients had a variety of diagnoses, including neuromuscular diseases, cerebral palsy with chronic respiratory insufficiency, asthma, and acute respiratory distress syndrome (ARDS), reflecting the diversity of patients with respiratory failure seen in our pediatric intensive care unit (ICU). Indications for noninvasive ventilation-assisted extubation were chronic respiratory insufficiency, clinical evidence the patient was falling extubation, or failure of a previous attempt to extubate. Extubation was successfully facilitated in 20 of 25 patients. Of the five patients failing an initial attempt at noninvasive ventilation-assisted extubation, two required tracheostomy, two were subsequently extubated with the aid of noninvasive ventilation, and one was subsequently extubated without the use of noninvasive ventilation. Risk factors for failure to successfully extubate with the assistance of noninvasive positive pressure ventilation included the patient's inability to manage respiratory tract secretions, severe upper airway obstruction, impaired mental status, and ineffective cough with mucus plugging of the large airways. AU patients had mild to moderate skin irritation due to the mask interface. No patient had any serious or long-term adverse effect of noninvasive positive pressure ventilation. All patients left the hospital alive. Noninvasive positive pressure ventilation can facilitate endotracheal extubation in pediatric patients with diverse diagnoses who have failed or who are at risk of failing extubation, including those with neuromuscular weakness.

Abstract Background Mechanical ventilation is the most widely used supportive therapy in intensive care units (ICU). Several forms of external support for respiration have been described to assist the failing ventilator pump and had constituted a major advance in the management of patients with respiratory distress. More recently, new noninvasive positive pressure ventilation (NIPPV) techniques, using patient/ ventilator interfaces in the form of facial masks, have been designed. Noninvasive ventilation (NIV) is one of the most important developments in respiratory medicine over the past 15 years and is increasingly used in many countries, but with a highly variable frequency of use. Objective The aim of this study is to clarify the role of non-invasive ventilation in preventing re-intubation if was used immediately following planned extubation in patients suffered respiratory failure in COPD patients and requiring invasive mechanical ventilation for 5 to 7 days. Methodology Forty consecutive patients, who are invasively mechanically ventilated and classified as difficult to wean from the ventilator in the intensive care units of Ain Shams main university hospital between the 1st April and 1st of September 2018, were included. The mean age in the present study for oxygen group was 56.20±5.56 years, while in NIV group was 57.75±5.17 years, 70% of patients in this present study were males. Results APACHE II score, PaO2 and mean arterial blood pressure which might have a role in respiratory failure showed no statistically significant differences between both study groups. Meanwhile, respiratory rate, pulse rate and arterial blood gases showed high significance between both study groups Conclusion The use of NIV is associated with a marked reduction in the need for endotracheal intubation after planned extubation.

P Value

Post-extubation respiratory failure requiring reintubation in a Pediatric Intensive Care Unit (PICU) results in significant morbidity. Data in the pediatric population comparing various therapeutic respiratory modalities for avoiding reintubation is lacking. Our objective was to compare therapeutic respiratory modalities following extubation from mechanical ventilation. About 491 children admitted to a single-center PICU requiring mechanical ventilation from January 2010 through December 2017 were retrospectively reviewed. Therapeutic respiratory support assisted in avoiding reintubation in the majority of patients initially extubated to room air or nasal cannula with high-flow nasal cannula (80%) or noninvasive positive pressure ventilation (100%). Patients requiring therapeutic respiratory support had longer PICU LOS (10.92 vs 6.91 days, P-value = .0357) and hospital LOS (16.43 vs 10.20 days, P-value = .0250). Therapeutic respiratory support following extubation can assist in avoiding reintubation. Those who required therapeutic respiratory support experienced a significantly longer PICU and hospital LOS. Further prospective clinical trials are warranted.
