Assisted autogenic drainage in infants and young children hospitalized with uncomplicated pneumonia, a pilot study

Development and learning efficacy of a simulation rubric in childhood pneumonia for nursing students: A mixed methods study

BACKGROUND

Nursing students often lack knowledge, skills, and appropriate attitudes toward chest physiotherapy, which affects the quality of care provided to children with pneumonia in clinical practice. Helping students learn about the effectiveness of simulations can improve their nursing ability.

OBJECTIVES

To develop a rubric associated with the simulation of childhood pneumonia and to examine the learning efficacy of students using the rubric to assess the knowledge, skills, and attitudes in the simulation.

DESIGN

A mixed methods study using a post-test survey and a descriptive qualitative analysis of students' reflective journals.

SETTINGS

A paediatric simulation classroom at the University Clinical Skills Centre in Northern Taiwan.

PARTICIPANTS

214 third-year students enrolled in a four-year nursing programme.

METHODS

Quantitative and qualitative data were collected after the course to obtain a comprehensive understanding of its effects. Quantitative data from the questionnaire were analysed using descriptive statistics. Qualitative data were analysed using content analysis.

RESULTS

The quantitative results showed that mean knowledge and nursing students' attitudes were moderate. Of the six sub-indices, chest percussion technique and communication with family and children had the highest mean with 3.32 ± 0.67 and 3.01 ± 0.68, respectively. The students discovered that they often focused on performing technical steps without pre-analysing patient information. Most students also indicated difficulty showing emotional caring behaviours toward patients. The qualitative results revealed that students reflected on their learning post-self-evaluation of the rubric, particularly regarding knowledge of systemic assessments, patient-centred nursing skills, and caring attitudes.

CONCLUSIONS

The knowledge, skills, and attitude rubric can help students develop their learning process in a more organised manner, promote the development of their caring performances toward children, and assist them in their future clinical care practices.

[Respiratory physiotherapy in pediatric practice]

Congestion of the upper (URT) and lower respiratory tracts (LRT) is a common symptom in several acute and chronic respiratory diseases that occur in childhood. To eliminate these secretions, airway clearance techniques (ACT) directed to the URT and LRT are frequently prescribed. The rationale for the application of these techniques is the same as in adults, but they need to be adapted to be transposed to children. The physiotherapist will be able to choose among a wide range of techniques, of which the most adequate will depend not only on the age of the child and the indication, but also on the basis of his preferences or habits, as well as those of the child. Upper airway clearance, including nasal irrigation, is now recommended for acute and chronic rhinosinusitis in children. It is also one of the symptomatic treatments recommended for infants with acute bronchiolitis. For LRT clearance, several indications, such as cystic fibrosis, primary ciliary dyskinesia and neuromuscular disease, are now widely advocated. Conversely, other indications, such as for infants with acute viral bronchiolitis, are highly controversial. Thoughtful application of these techniques is lacking in robust and precise tools to objectively assess the presence of bronchial congestion, and to treat it accordingly. Similarly, no precise and reliable evaluation of the effectiveness of these ACTs is available to date. This review is designed to explore the ACTs used by physiotherapists, to provide an overview of their current indications, and to consider complementary approaches.

The effects of assisted autogenic drainage, combined or not with bouncing on gastroesophageal reflux in infants

AIM

This study aimed to determine the effect of assisted autogenic drainage (AAD) with or without bouncing (BAAD) on both acid and non-acid gastroesophageal reflux (GER) in infants <1 year.

METHODS

During a 24-h multichannel intraluminal impedance-pH monitoring (MII-pH), infants were treated with a 20-min intervention of AAD (in supine position) or BAAD (in upright position), 2 h postprandial. In this controlled trial with intra-subject design, the number of reflux episodes (REs) was the primary outcome measure. The results during AAD and BAAD were compared to a baseline period before intervention and 20 min after intervention.

RESULTS

Overall, 50 infants were included in both groups. During AAD a significant decrease of RE's was found compared to baseline (p = 0.001). No significant differences were found in the BAAD group compared to baseline (p = 0.125).

CONCLUSION

AAD and BAAD do not cause or increase GER in infants under the age of 1 year.

Use of airway clearance therapy in children hospitalised with acute lower respiratory tract infections in a South African paediatric hospital

BACKGROUND

Little is known about the prescription, frequency and nature of airway clearance therapy (ACT) in children hospitalised with lower respiratory tract infections (LRTIs).

OBJECTIVES

To describe the characteristics and outcomes of children hospitalised with LRTIs at a tertiary paediatric hospital in South Africa and to investigate the role and impact of ACT in these children.

METHOD

A retrospective folder review of children hospitalised with LRTI between January and June 2015 was conducted, extracting data on demographic characteristics, health condition, ACT interventions and patient outcomes.

RESULTS

A total of 1208 individual cases (median [IQR] age 7.6 (2.8-19.0) months), in 1440 hospitalisations, were included. The majority of children were hospitalised primarily for the management of bronchiolitis. Comorbidities were present in 52.6% of patients during at least one of their hospitalisations. Airway clearance therapy was administered in 5.9% (n = 85) of admissions, most commonly conventional (manual) ACT. Transient oxyhaemoglobin desaturation was reported in six children, and one child developed lobar collapse an hour post-treatment. No other adverse events were reported. The median (IQR) duration of hospitalisation was 2.3 (1.5-5.0) days, and the overall mortality rate was 0.7%. Children hospitalised for presumed nosocomial infections and pneumonia had the longest length of stay, were more likely to receive ACT and had the highest mortality rate.

CONCLUSION

Airway clearance therapy was infrequently used in this population and was more commonly applied in those with nosocomial LRTI and pneumonia.

CLINICAL IMPLICATIONS

Although ACT was generally well tolerated, safety has not been ascertained, and oxygen saturation should be carefully monitored during therapy.

Positive expiratory pressure (PEP) therapy. What pressures do we achieve in young children with cystic fibrosis? A single-centre study

This study was a clinical review of infant positive expiratory pressure (PEP) therapy in young children with cystic fibrosis (CF). The aim of this study was to determine whether pressures of 10-20 cm H₂O PEP therapy (recommended by the CF trust) are being achieved with routine airway clearance therapy. This took place at the Royal Hospital for Children, Glasgow a specialist UK CF centre. Values were obtained from 21 young children. Pressures above 10 cm H₂O during tidal volume breathing were not achieved within our cohort. Further investigation is required to determine efficacy of lower pressures in PEP therapy with young children.

Airway clearance therapy in acute paediatric respiratory illness: A state-of-the-art review

Background

Despite unclear evidence of effectiveness or safety, airway clearance therapy (ACT) is frequently performed in infants and children with acute pulmonary disease.

Objectives

The aim of this review was to critically synthesise published evidence, expert opinion and pathophysiological principles to describe the indications, effects, precautions and application of commonly used ACT modalities for managing infants and children with acute pulmonary disease.

Method

A comprehensive narrative review of published literature was conducted. Articles describing paediatric populations were prioritised, but adult and animal studies were also considered where appropriate.

Results

There is a dearth of high-level evidence supporting the use of ACT in acutely ill infants and children. Conversely, studies have highlighted the lack of effect of different modalities for a variety of conditions, and in some cases serious associated complications have been reported.Airway clearance therapy may be considered when there is retention of pulmonary secretions, and the consequential airway obstruction impacts either acutely on respiratory mechanics and gaseous exchange and/or has the potential for long-term adverse sequelae [a condition that is the consequence of a previous disease or injury]. However, it should not be considered a routine intervention.

Conclusion

Airway clearance therapy should not be performed routinely in children admitted to hospital with acute respiratory conditions. Patients should be clinically assessed and treatment planned according to individual presentation, in those with signs and symptoms that are potentially amenable to ACT.

Clinical implications

This review can serve as a guide for physiotherapists in the respiratory management of children with acute respiratory illness, as well as identifying areas for clinical research.

Chest physiotherapy for pneumonia in children

BACKGROUND

Pneumonia is a lung infection that causes more deaths in children aged under five years than any other single cause. Chest physiotherapy is widely used as adjuvant treatment for pneumonia. Physiotherapy is thought to help remove inflammatory exudates, tracheobronchial secretions, and airway obstructions, and reduce airway resistance to improve breathing and enhance gas exchange. This is an update of a review published in 2013.

OBJECTIVES

To assess the effectiveness of chest physiotherapy with regard to time until clinical resolution in children (from birth to 18 years) of either gender with any type of pneumonia.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1), which includes the Cochrane Acute Respiratory Infections Group Specialised Register, MEDLINE (22 February 2018), Embase (22 February 2018), CINAHL (22 February 2018), LILACS (22 February 2018), Web of Science (22 February 2018), and PEDro (22 February 2018). We also searched clinical trials registers (ClinicalTrials.gov and WHO ICTRP) to identify planned, ongoing, and unpublished trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared any type of chest physiotherapy with no chest physiotherapy for children with pneumonia.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. The primary outcomes of interest were mortality, duration of hospital stay, and time to clinical resolution. We used Review Manager 5 software to analyse data and GRADE to assess the quality of the evidence for each outcome.

MAIN RESULTS

We included three new RCTs for this update, for a total of six included RCTs involving 559 children aged from 29 days to 12 years with pneumonia who were treated as inpatients. Pneumonia severity was described as moderate in one trial, severe in two trials, and was not stated in three trials. The studies assessed five different interventions: effects of conventional chest physiotherapy (3 studies, 211 children), positive expiratory pressure (1 study, 72 children), continuous positive airway pressure (CPAP) (1 study, 94 children), bubble CPAP (bCPAP) (1 study, 225 children), and assisted autogenic drainage (1 studies, 29 children). The included studies were conducted in Bangladesh, Brazil, China, Egypt, and South Africa. The studies were overall at low risk of bias. Blinding of participants was not possible in most studies, but we considered that the outcomes were unlikely to be influenced by the lack of blinding.All included studies evaluated mortality. However, three studies assessed mortality as an outcome, and only one study of bCPAP reported that deaths occurred. Three deaths occurred in children in the physiotherapy group (N = 79) and 20 deaths in children in the control group (N = 146) (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.08 to 0.90; 559 children; low-quality evidence). It is uncertain whether chest physiotherapy techniques (bCPAP, assisted autogenic drainage, and conventional chest physiotherapy) reduced hospital stay duration (days) (mean difference (MD) 0.10, 95% CI -0.56 to 0.76; 4 studies; low-quality evidence).There was variation among clinical parameters used to define clinical resolution. Two small studies found no difference in resolution of fever between children in the physiotherapy (conventional chest physiotherapy and assisted autogenic drainage) and control groups. Of five studies that considered peripheral oxygen saturation levels, only two reported that use of chest physiotherapy (CPAP and conventional chest physiotherapy) showed a greater improvement in peripheral oxygen saturation levels. However, it was unclear whether respiratory rate (breaths/min) improved after conventional chest physiotherapy (MD -2.25, 95% CI -5.17 to 0.68; 2 studies, 122 children; low-quality evidence). Two studies assessed adverse events (number of events), but only one study reported any events (RR 1.28, 95% CI 0.98 to 1.67; 2 studies, 254 children; low-quality evidence).

AUTHORS' CONCLUSIONS

We could draw no reliable conclusions concerning the use of chest physiotherapy for children with pneumonia due to the small number of included trials with differing study characteristics and statistical presentation of data. Future studies should consider the following key points: appropriate sample size with adequate power to detect expected differences, standardisation of chest physiotherapy techniques, appropriate outcomes (such as duration of leukocytosis, and airway clearance), and adverse effects.
