However, perioperative risks are not well established, assessment of routine preoperative polysomnography not feasible. The objective of the study was to evaluate the economic and technical viability (frequency of failure) of unsupervised polysomnography in children before adenotonsillectomy. Methods: The prospective study was approved by the local research ethics committee. 146 children, 57 male, aged 3 to 11 years, with indication of adenotonsillectomy, were invited to preoperative polygraphic monitoring. We analyzed the frequency of failed exams, failures per sensor, its correlation to age of the children and compared costs to standard full-night polysomnography. Results: General failure rate was 28.08% (n = 41), with no difference between genders (χ2=0.0644 p=0.7997), but a greater risk for preschool children (RR =1.2386 (CI 95%: = 0.724 to 2.118). Failure of oximetry was observed in 14.3%, nasal cannula in 10.2%, combination of both in 4.1%., thoracoabdominal belt in none. Costs of the unsupervised PSG was estimated to be 63% of the standard PSG, even if including the high failure rate being more cost saving. Conclusion: Unsupervised polysomnography was technically and economically feasible, its installation to be performed by trained professionals to avoid failure of sensors, mostly oximetry.","PeriodicalId":116156,"journal":{"name":"Paediatric respiratory physiology and sleep","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116551032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies also show that prematurity affects respiratory muscle (RM) function at the long term, albeit the effects on exercise capacity remain unknown. Aim: To investigate the role of RM function in the complex relationship between preterm birth and exercise capacity in childhood. Methods: 34 children (age 6.4 ± 0.2 years) born between 29 and 40 weeks of gestational age (GA), underwent spirometry, measurement of lung volumes, measurement of RM function, and cardiopulmonary exercise testing (standardized cycle-ergometer protocol). RM function was assessed by means of the tension-time index (TTmus), while exercise capacity by means of maximum oxygen consumption (VO2max) and maximum achieved work (Wmax). Results: Preterm-born children (N=16) had higher TTmus (0.11±0.02 vs. 0.09±0.02; P=0.014) compared to those born at term (N=18); they also achieved lower Wmax (116±8 vs. 124±7 Watts; P=0.005) and slightly lower VO2max (32.8±4.9 vs. 36.6±8.8 mlO2/kg/min; P=0.124). There were no differences in spirometric indices between the two groups. GA was significantly correlated with TTmus (r –0.551; P=0.001), and Wmax (r 0.539; P=0.001), but not with VO2max. TTmus, in turn, was significantly correlated with VO2max, especially in preterm-born children (r –0.519; P=0.039). The above relationship remained strong after adjustment for somatometric and spirometric characteristics (multivariable regression). Conclusions: Preterm birth influences RM function at the long term and, through this effect, may be a significant determinant of exercise capacity later in life.","PeriodicalId":116156,"journal":{"name":"Paediatric respiratory physiology and sleep","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125338376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new infant SF6 MBW methodology using currently available equipment was recently proposed. Aims: We compared lung clearance index (LCI) and functional residual capacity (FRC) outcomes in healthy infants from the new SF6 MBW technique with published normative data. Methods: Unselected healthy infants from the prospective Bern-Basel Infant Lung Development (BILD) birth cohort underwent MBW measurements using the new SF6 MBW technique (Spiroware 3.2; Ecomedics, Duernten, Switzerland). Measurements were performed in unsedated infants during quiet natural sleep according to the ATS/ERS standards. We report the mean (standard deviation (SD)), within-test coefficient of variation (CV), and upper limit of normal (mean + 1.64*SD). Results: We performed MBW measurements using the new method in 28 healthy infants. Two technically acceptable measurements were available in 23 healthy infants (82%) at ~5 weeks post-natal age (51% male, age: 5.5 weeks (0.9), weight: 4.5kg (0.6)). Mean FRC adjusted for weight was 17.2 (3.5) ml/kg (CV: 6.8%) and mean LCI was 7.2 (0.7) (CV: 9.7%, ULN: 8.3). These values differ considerably from published normative data using Wbreath software (FRC: 23.9 (4.0) ml/kg; LCI: 6.8 (0.6); Fuchs et al. 2011). Conclusions: Measurements from the new SF6 MBW setup generate FRC values approximately 30% higher and LCI 6% lower than for the former setup. These preliminary data highlight the need for new equipment specific reference values.","PeriodicalId":116156,"journal":{"name":"Paediatric respiratory physiology and sleep","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114335669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims and Objectives: The aim of this study was to evaluate the lung function in these cases in comparison with the volumes of normal age-sex matched children. Method: 87 children with idiopathic scoliosis (72 girls, 84%, mean age 13y ± 1.6y) and 27 children with idiopathic kyphosis (11 girls, 40.7%, mean age 13.4y ± 1.6y were reviewed. Thoracic cage enlargement, oxygen saturation and respiratory volumes were recorded prior to any therapeutic intervention and compared to normal children. Results: Seventeen (19.3%) cases had thoracic , 47 (27.6%) cases thoracic and lumbar and 24 (54%) cases lumbar scoliosis. Forty children (46%) suffered from mild, 39 (44.8%) moderate and 8 (9.2%) severe scoliosis. Fourteen (51.8%) children had moderate and 13 (48.2%) severe kyphosis. A significant difference of FVC and FEV1 was found among children with thoracic scoliosis and kyphosis as well as among children with mild / moderate and severe scoliosis. In addition, there was a significant difference between lung volumes in the general population compared to the children with scoliosis, which was not found in children with kyphosis. Conclusions: Thoracic scoliosis appears to significantly affect children’s respiratory function according to the severity, such an effect is not encountered in children with kyphosis.","PeriodicalId":116156,"journal":{"name":"Paediatric respiratory physiology and sleep","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132085907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: We hypothesised that preterm-born children who had chronic lung disease of prematurity (CLD) in infancy, have lower ventilatory efficiency (steeper minute volume [VE]/carbon dioxide uptake[VCO2] slope) during exercise than preterm- and term-born controls. Methods: From our on-going RHiNO (Respiratory Health Outcomes in Neonates) study, 7-12 years old children, born at ≤34 weeks’ gestation, with and without, a history of CLD, and term-born controls, underwent spirometry and exercise testing using cycle ergometry. Breath-by-breath measurements were averaged over 5-second intervals. The VE/VCO2 slope was estimated for each child (VE=a+b[VCO2]). The regression coefficients were then modelled with explanatory variables, using VE as the outcome. Results: Twenty-two children with a history of CLD, 28 preterm and 19 term controls completed the exercise protocol. The linear model was a good fit for the data (median R2= 0.98 range 0.75-0.99). The VE/VCO2 slope was noted to be higher in the CLD group (mean±SD 29.4±3.1) when compared to preterm (28.5±3.3) and term (27.5±6.0) controls, however, the groups were not statistically different (ANOVA p=0.3).
