Risk Factors for Functional Decline and Impaired Quality of Life after Pediatric Respiratory Failure.

ABSTRACT: Rationale: Poor outcomes of adults surviving critical illness are well documented, but data in children are limited.Objectives: To identify factors associated with worse postdischarge function and health-related quality of life (HRQL) after pediatric acute respiratory failure.Methods: We assessed functional status at baseline, discharge, and 6 months after pediatric ICU discharge and HRQL 6 months after discharge in 2-week- to 17-year-olds mechanically ventilated for acute respiratory failure in the RESTORE (Randomized Evaluation of Sedation Titration for Respiratory Failure) trial. We assessed HRQL via Infant and Toddler Quality of Life Questionnaire-97 (<2 yr old) or Pediatric Quality of Life Inventory (≥2 yr old). We categorized patients with normal baseline function as having impaired HRQL if scores were greater than 1 SD below mean norms for Infant and Toddler Quality of Life Questionnaire-97 growth and development or Pediatric Quality of Life Inventory total score.Measurements and Main Results: One-fifth (n = 192) of 949 patients declined in function from baseline to postdischarge; 20% (55/271) had impaired growth and development; 19% (64/343) had impaired HRQL. In multivariable analyses, decline in function was associated with baseline impaired function, prematurity, cancer, respiratory failure etiology, ventilation duration, and clonidine (odds ratio [OR] = 2.14; 95% confidence interval [CI] = 1.22-3.76). Independent predictors of impaired growth and development included methadone (OR = 2.27; 95% CI = 1.18-4.36) and inadequate pain management (OR = 2.94; 95% CI = 1.39-6.19). Impaired HRQL was associated with older age, non-white or Hispanic race, cancer, and inadequate sedation management (OR = 3.15; 95% CI = 1.74-5.72).Conclusions: Postdischarge morbidity after respiratory failure is common and associated with admission factors, exposure to critical care therapies, and pain and sedation management.

Project description:OBJECTIVE:Respiratory muscle weakness frequently develops during mechanical ventilation, although in children there are limited data about its prevalence and whether it is associated with extubation outcomes. We sought to identify risk factors for pediatric extubation failure, with specific attention to respiratory muscle strength. DESIGN:Secondary analysis of prospectively collected data. SETTING:Tertiary care PICU. PATIENTS:Four hundred nine mechanically ventilated children. INTERVENTIONS:Respiratory measurements using esophageal manometry and respiratory inductance plethysmography were made preextubation during airway occlusion and on continuous positive airway pressure of 5 and pressure support of 10 above positive end-expiratory pressure 5?cm H2O, as well as 5 and 60 minutes postextubation. MEASUREMENTS AND MAIN RESULTS:Thirty-four patients (8.3%) were reintubated within 48 hours of extubation. Reintubation risk factors included lower maximum airway pressure during airway occlusion (aPiMax) preextubation, longer length of ventilation, postextubation upper airway obstruction, high respiratory effort postextubation (pressure rate product, pressure time product, tension time index), and high postextubation phase angle. Nearly 35% of children had diminished respiratory muscle strength (aPiMax ? 30 cm H2O) at the time of extubation, and were nearly three times more likely to be reintubated than those with preserved strength (aPiMax > 30 cm H2O; 14% vs 5.5%; p = 0.006). Reintubation rates exceeded 20% when children with low aPiMax had moderately elevated effort after extubation (pressure rate product > 500), whereas children with preserved aPiMax had reintubation rates greater than 20% only when postextubation effort was very high (pressure rate product > 1,000). When children developed postextubation upper airway obstruction, reintubation rates were 47.4% for those with low aPiMax compared to 15.4% for those with preserved aPiMax (p = 0.02). Multivariable risk factors for reintubation included acute neurologic disease, lower aPiMax, postextubation upper airway obstruction, higher preextubation positive end-expiratory pressure, higher postextubation pressure rate product, and lower height. CONCLUSIONS:Neuromuscular weakness at the time of extubation was common in children and was independently associated with reintubation, particularly when postextubation effort was high.

Project description:BackgroundIt remains controversial as to whether delayed gastric emptying in functional dyspepsia is associated with a specific symptom pattern, and it is unknown if gastric emptying in functional dyspepsia is a driver of impaired health related quality of life (HRQOL). We aimed to evaluate the relationship between functional dyspepsia symptoms, gastric emptying, and HRQOL.MethodsUS patients (n=864; mean age 44 years (range 18-82); 74% female) with functional dyspepsia, as defined by Rome II criteria, were enrolled into one of four clinical trials. All patients had a baseline scintigraphic assessment of gastric emptying of an egg substitute meal, and the trials were stratified on this assessment. Delayed gastric emptying was defined as having at least 6.3% residual volume at four hours. A total of 290 (34%) patients had delayed gastric emptying. HRQOL was assessed by the SF 36 and Nepean dyspepsia index (NDI).ResultsPostprandial fullness was independently associated with delayed gastric emptying but the association was weak (odds ratio (OR) 1.98 (95% confidence interval (CI) 1.02, 3.86); p=0.04). No independent association was seen with epigastric pain, early satiety, nausea, or bloating. Mean SF 36 physical composite score (PCS) was 42.3 (95% CI 41.6, 43.0) and the mean SF 36 mental composite score (MCS) was 46.8 (95% CI 46.0, 47.5); both mean scores were significantly lower than age and sex adjusted national norms of 50 (p<.0001). Female sex, increasing age, and higher symptom scores for fullness, epigastric pain, and nausea were each independently associated with decreased PCS scores (all p<0.05). Higher baseline nausea symptom score, lower gastric emptying rates at one hour, and lower body mass index were associated with decreased MCS (all p<0.05). Female sex, epigastric pain, and nausea, but not gastric emptying, were associated with an impaired score on the NDI. However, the magnitude of the significant associations were all small.ConclusionsIn patients with functional dyspepsia selected for a clinical trial programme, gastric emptying did not usefully stratify them symptomatically. Quality of life of patients with functional dyspepsia enrolled in this clinical trial programme was significantly impaired but this was not explained by delayed gastric emptying.
