Efficacy of standardized tracheostomy training with a simulation model for healthcare providers: A study by ISPAT team.

INTRODUCTION: Tracheostomy care in children may be challenging, due to lack of knowledge of healthcare providers (HCPs). The aim of this study was to determine the level of knowledge of HCP who follow patients with tracheostomy and to increase this level with theoretical training and training in a simulation laboratory. MATERIALS AND METHODS: ISPAT (IStanbul PAediatric Tracheostomy), a multidisciplinary team for tracheostomy care was established and a training program was prepared. Participants were subjected to theoretical and practical pretests which evaluated their knowledge levels and skills for care, follow-up, and treatment of a patient with tracheostomy. After the theoretical and practical training given to the participants with a simulation model, theoretical and practical posttests were applied. RESULTS: Fifty-one HCP from nine tertiary pediatric clinics in Istanbul were enrolled in the training program. Only six (11.8%) of them had received standardized training programs previously. Regarding the theoretical tests, seven of the 33 questions were indicated as essential. The knowledge level of the participants based on the essential questions significantly increased after the training (p < 0.05 for all of the essential questions). The total number of correct answers and correct answers of three subheadings also significantly increased after the practical training (p < 0.001 for all). Ninety-five percent of the participants assessed the course as good or excellent in general. CONCLUSION: Training in a simulation laboratory in combination with theoretical education can improve the knowledge and skills of the HCP enabling improved care of children with a tracheostomy.

Respiratory function in children with nephrotic syndrome: Comparative evaluation of impulse oscillometry and spirometry.

AIM: To evaluate the respiratory functions of children with nephrotic syndrome (NS) by impulse oscillometry (IOS) and its correlation with spirometry. METHODS: Fifty-five NS patients aged 3-18 years were included as the study group and 40 healthy children of the same age formed the control group. Patients were divided into nephrotic phase (first attack and relapse) and remission. Demographic, anthropometric, and laboratory data of the children were recorded. Respiratory functions were evaluated by IOS and spirometry. Children over 6-years old performed both IOS and spirometry while children under 6 years performed only IOS. RESULTS: The R (R5%, R10%, R5-20), AX and Z5% values of IOS in patients with nephrotic phase were higher than remission patients and control group while spirometry indices of PEF% and MEF25-75% were lower. Z scores of MEF25-75 were significantly negatively correlated with z scores of R5, R10, Z5, and Fres while they were significantly positively correlated with z scores of X values (5, 10, 15, and 20 Hz). Z scores of forced expiratory volume in 1 /forced vital capacity significantly negatively correlated with z scores of R values (R5, R10), Z5 and AX and positively correlated with z scores of X values (X5, X10, X15 Hz). CONCLUSION: Our study demonstrated that respiratory functions measured by IOS and spirometry were affected at the time of nephrotic phase in NS patients. IOS, a novel method easily applicable even in small children, is a potentially valuable tool to detect this condition; given its good correlation with spirometry.

Effect of occupation and smoking on respiratory symptoms in working children.

OBJECTIVES: To compare the respiratory symptoms and the lung function of children who work in different occupational groups. METHODS: The study was performed among children attending vocational training centers. The participants were evaluated in six different occupation groups. Chronic cough, wheezing and shortness of breath were evaluated by questionnaire. The association of independent variables with the respiratory symptoms was investigated through both univariate and multivariate methods. RESULTS: Among 642 children, 534 were males; the mean age was 17.7 +/- 1.0 years. Using an internal reference group, the odds ratios of chronic cough were significantly higher in the lathe (OR: 2.0, 95%CI: 1.07-3.74), coiffure (OR: 1.94. 95%CI: 1.01-3.70), and electricity-construction (OR: 2.63, 95%CI: 1.06-6.54) groups after adjustment for smoking, age, gender, and work characteristics. There were no significant differences in spirometric values between occupational groups in either smoking or non-smoking males. In non-smoking females, median values of FEV(1) (P: 0.046), PEF (P: 0.005) and FEF(25-75%) (P: 0.019) were lower in the textile compared to the coiffure group. There was no significant association between the total working time and spirometric values. There was no statistically significant relationship between the work-related factors and the smoking status. CONCLUSIONS: The prevalence of chronic cough was higher in the lathe, coiffure, and electricity-construction groups and pulmonary function tests were lower in the non-smoking textile female group. Working children should be screened for respiratory symptoms and disease.

Evaluation of children with cystic fibrosis by impulse oscillometry when stable and at exacerbation.

BACKGROUND: Pulmonary function tests are important in the diagnosis and follow-up of airway disease in cystic fibrosis (CF). Conventional spirometry for which repeated forced expiration maneuver are needed is considered as the main method. Impulse oscillometry (IOS) is a non-invasive method, which needs minimal cooperation. We performed a prospective cross-sectional study to determine the pulmonary function in CF children with IOS, and evaluate the IOS measurements during acute exacerbation. We hypothesized that IOS can detect lung function impairment in CF patients and detect changes during acute exacerbations. METHODS: CF patients aged 3-18 years were included as the study group and healthy children of the same age formed the control group. The patients were evaluated three times at 3-month intervals. Patients aged >6 years performed both spirometry and IOS while patients aged ≤6 years performed only IOS. In patients with acute exacerbation, spirometry and IOS were performed both at and after the exacerbation. RESULTS: Forty-nine CF patients and 45 healthy children were enrolled to the study. Sixteen patients were admitted with acute exacerbation during the study. The resistance values (R5-10-15-20 Hz) as well as Z5, Fres, and AX values of the patients were higher than those of the control group, while reactance values (X5-10-15-20 Hz) were lower. R values as well as Z5, Fres, and AX values increased during exacerbation and decreased after treatment; X (10-15 Hz) values decreased during exacerbation and increased after recovery (P < 0.05). CONCLUSIONS: IOS may be useful to evaluate pulmonary functions and detect acute exacerbations in CF patients. Pediatr Pulmonol. 2016;51:1151-1158. © 2016 Wiley Periodicals, Inc.

Sleep disordered breathing and sleep quality in children with bronchiolitis obliterans.

The incidence of sleep-disordered breathing (SDB) increases in chronic lung diseases. Our aim was to evaluate SDB and sleep quality in children with postinfectious bronchiolitis obliterans (BO) and assess associated risk factors. We hypothesized that children with BO are at increased risk for SDB and have impaired sleep quality. We also hypothesized that severity of SDB and impairment of sleep quality is related to the severity of lung disease. Sleep Related Breathing Disorder (SRBD) subscale of the Pediatric Sleep Questionnaire (PSQ) and Pittsburgh Sleep Quality Index (PSQI) questionnaires; spirometry, impulse oscillometry (IOS), and overnight polysomnography (PSG) were performed. Twenty-one patients (14 male, median age: 8.3 years) were enrolled. Five patients (25%) had a PSQ score of >0.33, predictive of a SDB. Ten patients (48%) had poor sleep quality. Four patients (19%) had an OAHI of >1/hr. Nineteen patients (90%) had a high desaturation index. Four patients (19%) had a mean oxygen saturation of <93%. Median central apnea time was 7.5 (IQR: 6.9-9.1) seconds. Central apnea index of the patients correlated positively with R5, R10, R15, R20, Z5, and negatively with X10 and X15 at IOS. There was a positive correlation between the lowest oxygen saturation and FVC, FEV1 , X5, X10, X15, X20 while there was a negative correlation between lowest saturation and the central apnea index at PSG, R5, R10, and Z5 at IOS. Mean oxygen saturation during PSG correlated positively with FVC, FEV1, FEF(25-75), X5, X10, X15, X20 results. The risk of nocturnal hypoxia is increased in patients with BO and correlated to the severity of lung disease determined by pulmonary function tests. Although BO patients have a shorter duration of central apneas, they are more prone to desaturate.

Exhaled air temperature in children with bronchopulmonary dysplasia.

BACKGROUND: Because they have similar functional and clinical profiles, bronchopulmonary dysplasia (BPD) survivors are often treated as asthmatic patients. In truth, very little is known about the possible biochemical and inflammatory mechanisms playing a part in BPD survivors' lungs. The aim of this study was to measure exhaled breath temperature in BPD survivors by comparison with asthmatic cases and healthy controls. METHODS: Three groups of age-matched adolescents (n = 17 each), that is, BPD survivors (gestational ages <31 weeks, birth weights <1,500 g), asthmatic subjects and healthy controls, underwent exhaled breath temperature and exhaled nitric oxide measurements, and spirometry. RESULTS: Exhaled breath temperature was significantly lower in the BPD survivors (26.72°C [25.11-27.57]) than in the asthmatic patients (29.60°C [29.20-30.02], P < 0.001), while no significant difference emerged by comparison with healthy controls (26.97°C [26.58-27.38]). Considering the whole study population, a significant correlation was found between exhaled breath temperatures and exhaled nitric oxide concentrations (R = 0.42, P = 0.004). Spirometry revealed an obstructive lung function pattern in both the asthmatic cases and the BPD survivors, with lower parameters in the latter. CONCLUSIONS: Exhaled breath temperatures and exhaled nitric oxide concentrations are significantly lower in BPD survivors than in asthmatic cases, suggesting that different pathogenetic mechanisms characterize these two chronic obstructive lung diseases.
