Project description:Objective To investigate the clinical outcomes of preterm infants who received non-invasive high-frequency oscillatory ventilation following extubation in a neonatal intensive care unit. Methods Infants born between 25 and 34 weeks of gestation with a birth weight of <1,500 g, who were admitted into the neonatal intensive care unit of Guangxi Maternal and Child Health Hospital, Nanning, Guangxi, China, requiring mechanical ventilation on admission were randomized to the non-invasive high-frequency ventilation group, nasal intermittent positive pressure ventilation group, or nasal continuous positive airway pressure group following extubation. Their respiratory and neurodevelopmental outcomes were assessed at 12 and 24 months of corrected age. Results Among 149 preterm infants who underwent randomization, 139 completed their treatment in the neonatal intensive care unit (45, 47, 47 in the non-invasive high-frequency ventilation group, nasal intermittent positive pressure ventilation group, or nasal continuous positive airway pressure group, respectively), 113 were assessed at 12-month corrected age, and 110 of 113 were assessed again at 24-month corrected age. There were no differences in the number of times bronchitis, pneumonia, wheezing episodes, and re-hospitalization rates appeared due to respiratory diseases among the three groups (P > 0.05); the pulmonary function tests at 12-month corrected age showed respiratory rate, tidal volume, inspiratory time/expiratory time, time to peak expiratory flow/expiratory time, volume at peak expiratory flow/expiratory volume, expiratory flow at 25, 50, and 75% tidal volume were all similar among infants from the 3 groups (P > 0.05). There were no differences in the rates of neurodevelopmental impairment among the three groups at 24-month corrected age (P > 0.05). Conclusion As post-extubation respiratory support in preterm infants, non-invasive high-frequency ventilation did not increase the rates of long-term respiratory morbidities and neurodevelopmental impairment compared with nasal intermittent positive pressure ventilation and nasal continuous positive airway pressure.

Project description:This review will focus on non-invasive ventilation (NIV) and continuous positive airway pressure (CPAP) therapy in children with obstructive sleep apnea (OSA) due to obesity and underlying syndromes. These children have a high prevalence of OSA and residual OSA after adenotonsillectomy. Therefore, a high proportion of these children are treated with CPAP or NIV. This review will focus on treatment selection tools and will subsequently cover specific issues on CPAP treatment in obese and syndromic children with a major focus on Down syndrome.

Project description:Background: Noninvasive ventilation (NIV) is accepted as standard of care for chronic hypercapnic respiratory failure (CHRF) and is being increasingly implemented in older subjects. However, little is known regarding the use of NIV on a long-term basis in the very old. The outcomes of this study were: 1/to report the proportion of patients ? 75 years old (elderly) among a large group of long-term NIV users and its trend since 2000; 2/to compare this population to a younger population (<75 years old) under long-term NIV in terms of diagnoses, comorbidities, anthropometric data, technical aspects, adherence to and efficiency of NIV. Methods: In a cross-sectional analysis of a multicenter cohort study on patients with CHRF under NIV, diagnoses, comorbidities, technical aspects, adherence to and efficiency of NIV were compared between patients ? 75 and <75 years old (chi-square or Welch Student tests). Results: Of a total of 489 patients under NIV, 151 patients (31%) were ? 75 years of age. Comorbidities such as systemic hypertension (86 vs. 60%, p < 0.001), chronic heart failure (30 vs. 18%, p = 0.005), and pulmonary hypertension (25 vs. 14%, p = 0.005) were more frequent in older subjects. In the older group, there was a trend for a higher prevalence of chronic obstructive pulmonary disease (COPD) (46 vs. 36%, p = 0.151) and a lower prevalence of neuromuscular diseases (NMD) (19 vs. 11%, p = 0.151), although not significant. Adherence to and efficacy of NIV were similar in both groups (daily use of ventilator: 437 vs. 419 min, p = 0.76; PaCO2: 5.8 vs. 5.9 kPa, p = 0.968). Unintentional leaks were slightly higher in the older group (1.8 vs. 0.6 L/min, p = 0.018). Conclusions: In this cross-sectional study, one third of the population under NIV was ? 75 years old. Markers of efficacy of NIV, and adherence to treatment were similar when compared to younger subjects, confirming the feasibility of long-term NIV in the very old. Health-related quality of life was not assessed in this study and further research is needed to address this issue.

Project description:BackgroundNon-invasive ventilation (NIV) is used to treat acute hypercapnic respiratory failure (AHRF) in patients with chronic obstructive pulmonary disease (COPD); however, long-term outcomes following discharge are largely unknown. This study aimed to characterize long-term outcomes and identify associated markers in patients with COPD after surviving the first episode of HRF requiring NIV.MethodsThis study retrospectively analyzed 122 patients, mean age 62 ± 8 years, 52% female and forced expiratory volume in 1 s (FEV1) predicted 30 ± 13%, admitted with an acute hypercapnic exacerbation of COPD and receiving a first-ever NIV treatment between 2000 and 2012.ResultsA total of 40% of the patients required hospital readmission due to respiratory reasons within 1 year. Persistent hypercapnia leading to the prescription of domiciliary NIV, older age and lower body mass index (BMI) were risk factors for readmission due to respiratory reasons. Survival rates were 79% and 63% at 1 and 2 years after discharge, respectively. A shorter time to readmission and recurrent hypercapnic failure, lower BMI and acidemia on the first admission, as well as hypercapnia at hospital discharge were correlated with a decreased long-term survival.ConclusionPatients with COPD surviving their first episode of AHRF requiring NIV are at high risk for readmission and death. Severe respiratory acidosis, chronic respiratory failure and a lower BMI imply shorter long-term survival.

Project description:BackgroundChronic hypercapnic respiratory failure (HRF) in obesity hypoventilation syndrome (OHS) is commonly treated using non-invasive ventilation (NIV). We hypothesised that treatment of OHS would improve neural respiratory drive index (NRDI) and cardiac function.MethodsFourteen patients (8 females) with OHS, who were admitted for initiation of domiciliary NIV, were prospectively studied. Patients had (mean ± SD): age (53±10 years), body mass index (BMI) (50.1±10.8 kg/m2), and pCO2 (7.3±0.9 kPa). NRDI was assessed by surface electromyogram of the parasternal intercostals. Cardiac function was assessed by transthoracic echocardiography (TTE). All measurements were performed at baseline, 6 weeks, and 3 months.ResultsNRDI improved on day one following NIV set-up comparing to baseline (484.2±214.8 vs. 316.5±106.5 AU) and this improvement was maintained at 6 weeks (369.1±173.2 AU) and at 3 months (351.2±167.1 AU) (P=0.004). No significant differences were identified in terms of cardiac function between baseline and 3 months [tricuspid annular plane systolic excursion (TAPSE) (24.6±5.8 vs. 23.0±4.0 mm, P=0.317); systolic pulmonary artery (PA) pressures (36.7±15.2 vs. 44.5±23.9 mmHg, P=0.163].ConclusionsNIV improves NRDI in patients with OHS, while the cardiac function over a three-month period remains unchanged.

Project description:RATIONALE:The decision of whether to initiate or forgo long-term ventilation (LTV) for children with life-limiting conditions can be complex and impactful. Providers are responsible for helping families to understand the consequences of their options and guiding them through shared decision-making, but little has been published on how to do this. OBJECTIVES:To assess how directors of pediatric home ventilation programs facilitate shared decision-making with families facing decisions of whether to initiate or forgo LTV for their children with life-limiting conditions. In addition, to assess directors' perspectives on these families' decisional needs. METHODS:Purposeful recruiting of directors/codirectors of pediatric home ventilation programs at children's hospitals was used. We performed semistructured interviews using an open-ended interview guide developed de novo to assess their approach to informed, shared decision-making around LTV and their perspectives on these decisions. Qualitative data analysis was conducted using a thematic approach based on framework analysis in which thematic saturation was achieved. RESULTS:A sample of 15 experienced physician directors across North America was interviewed. All (15/15) inform families of the potential benefits and burdens/risks of LTV for the child and of the option to forgo LTV. All stress to families the physical, emotional, and social impact of caring for a child using LTV on the family; 12 directors also highlight the financial impact. All recommend that decision-making around LTV should be interdisciplinary, initiated early, and not rushed; nine described their approach as guided by the family's goals for the child and their family. All recommend that providers be transparent, candid, active listeners, and supportive. All directors believe that the family's decision should be respected, but vary in the extent to which they recommend an option to families. They described barriers to decision-making that stem from families, providers, and other sources. CONCLUSIONS:As providers who follow children using LTV, directors of pediatric home ventilation programs have perspectives regarding the decisional needs of these families and how to meet them that can help inform and shape the practices of other providers who assist families facing this decision.

Project description:Rationale: The decision whether to initiate or forgo long-term ventilation for children can be difficult and impactful. However, little has been published on the informational and decisional needs of families facing this decision.Objectives: To assess what families with children with chronic respiratory failure and life-limiting conditions need and want for informed decision-making.Methods: English- and Spanish-speaking parents who were facing (contemporaneous decision makers) or had previously faced (former decision makers) a decision regarding invasive or noninvasive long-term ventilation for their children were recruited using convenience sampling. Patients who were older and cognitively capable also were invited to participate. We performed semistructured interviews using an open-ended interview guide developed de novo to assess parents' decisional needs and experiences. Qualitative data analysis used a thematic approach based on framework analysis, and thematic saturation was a goal.Results: A sample of 44 parents and 2 patients from 43 families was interviewed. All contemporaneous decision makers (n = 28) favored or believed that they would choose long-term ventilation. Fifteen of 16 former decision makers chose long-term ventilation. Thematic saturation was achieved from the perspective of parents who favored or chose long-term ventilation. Four domains were identified: parents' emotional and psychological experiences with decision-making, parents' informational needs, parents' communication and decision support needs, and parents' views on the option not to initiate long-term ventilation. For most parents, making a decision regarding long-term ventilation was stressful, even though they articulated goals and values that could/did guide their decision-making. In general, parents wanted comprehensive information, including what life would be like at home for the child and the family. They wanted their medical providers to be honest, tactful, patient, and supportive. Parents reported that they felt being presented with the option not to initiate was acceptable.Conclusions: In this study, we identified specific informational and decision-making needs regarding long-term ventilation that parents facing decisions feel are important. These data suggest that providers should present families with comprehensive, balanced information on the impact of long-term ventilation and, when the child has a profoundly serious and life-limiting condition, explore the option not to initiate long-term ventilation.

Project description:Record keeping for patients on non-invasive ventilation (NIV) at St. Georges Hospital is poor. The initial NIV prescription is often not recorded, and changes to the NIV prescription or the rationale for the changes (ABG results) are also poorly documented. This leads to confusion for nurses/doctors as to what the correct settings are, meaning patients could receive ineffective ventilation. The use of NIV is also poorly recorded by nursing staff meaning that doctors are unsure if the prescribed NIV is being achieved. This can lead to treatment being escalated unnecessarily in the event of treatment failure. Non-invasive ventilation (NIV) is the provision of ventilatory support in the form of positive pressure via the patient's upper airway using a mask or similar device. NIV is indicated for treatment of acute hypercapnic respiratory failure, of which there are many causes, though COPD is the indication in up to 70% of cases.[1] British Thoracic Society (BTS) guidelines for NIV suggest that the rationale for commencing a patient on NIV and the proposed settings should be clearly documented.[2] Clinicians cannot effectively tailor changes to the patients NIV settings if this information is not clearly recorded, which could lead to increased time requiring NIV or NIV failure. Three main areas were considered important to measure for this project. The initial prescription of the NIV, changes to the NIV settings, and nursing documentation surrounding NIV. A baseline measurement of NIV documentation for two weeks found NIV documentation to globally very poor. NIV was formally prescribed 29% of the time, full detail of intended settings were documented 57% of the time, the decision to commence NIV was discussed with the respiratory consultant/SpR just 29% of the time and on no occasion was a decision regarding escalation of treatment recorded. Eighteen changes were made to the NIV settings. These were formally prescribed 22% of the time and detail of the intended settings was recorded 44% of the time. Nursing documentation included detail on the length of NIV use just 21% of the time, and comments on the NIV use were left just 33% of the time. The intervention was a unified four page NIV prescription chart. Page 1: An area for the NIV to be initially prescribed with reminder questions for important considerations. Page 2: An area for changes to be made to the NIV settings. Page 3: An area for the most up to date NIV/respiratory plan to be documented. Page 4: Nursing documentation, with prompts for the time NIV was put on/off and for comments. The chart was printed at St Georges print services and paid for by the respiratory ward. A further two weeks of monitoring followed after implementation of the new chart. Improvements were seen in all areas of documentation surrounding NIV. The NIV was formally prescribed 86% of the time compared to 29% pre-intervention. The NIV settings were stated 100% of the time in the initial prescription. An escalation decision was recorded 71% of the time. Changes to the NIV settings improved to 92%. Nursing documentation improved greatly. The length of the NIV use was recorded for 91% of NIV days compared to 21% previously (p<0.001), and comments on the use of NIV improved from from 33% to 98% (p<0.001). Cases where the documentation remained poor were in those patients for whom the new chart had not been used. The implementation of a unified NIV prescription chart to be kept in the bedside notes on the respiratory ward greatly improved documentation surrounding NIV. Further work must be done to ensure that the chart is used 100% of the time. This will include adjusting the chart to reduce the workload to use it, rolling the chart out on the acute medical ward, and submitting the chart to the trust board for its acceptance as an official trust chart.

Project description:Home ventilation is an effective treatment option for obesity hypoventilation syndrome (OHS). This therapy is still controversial for stable chronic obstructive pulmonary disease (COPD). A recent study showed reduced mortality for COPD patients receiving home ventilation with high inflation pressures and back-up respiratory rates [so called High Intensity non-invasive ventilation (NIV)].The purpose of this study is whether High Intensity NIV applied in the routine care of COPD and OHS patients can lead to CO2 reduction and survival data comparable to data from controlled studies.In this prospective non interventional study fifty-one patients with COPD (FEV1 0.95l, corr. 32.8%) and 34 patients with OHS (VC 1.74l, corr. 50.7%) with chronic hypercapnic respiratory failure, who were treated with NIV were followed up for four years.Elevated CO2 values before NIV in COPD patients (8.6kPa), and in OHS patients (8.3kPa), could be lowered significantly to the upper normal range (COPD: 5.9kPa; OHS: 5.85kPa). The one-, two-, and three-year survival rates for COPD patients were 83%, 73%, and 55%, respectively. The one-, two-, and three-year survival rates for OHS patients were 85%, 72%, and 68%, respectively.High intensity NIV within routine care is effective in reducing blood CO2 levels in COPD- and in OHS- related chronic respiratory insufficiency. The survival rates obtained here are comparable to data from controlled clinical trials on COPD.
