Chest Physiotherapy Interventions for Children During SARS-COV-2 Pandemic

Since the first case of Severe Acute Respiratory Syndrome Coronavirus-2/Coronavirus Disease 2019 (SARS-COV-2/COVID-19) was discovered in Wuhan, China, it spread to vast limits globally and became a public health disaster, affecting nearly all countries around the globe. Along with mainstream medical treatment, alternative medicine desperately was the need of the hour for youngsters to manage their symptoms while being self-quarantined and ultimately to improve their chances of survival and recovery from COVID-19. Since the beginning of SARS-COV-2, few studies address the clinical-functional presentation of viral infection and management with physiotherapy for children. Major online electronic databases PubMed, PEDro, and Google Scholar were researched to identify, organize and commission the current review. To create a search strategy, Medical Subject Headings and Descriptors of Science and Health were utilized. The authors looked for other studies by screening the references list of the potentially pertinent papers. These computerized searches turned up studies and those studies' bibliographies with pertinent citations were examined. Personal protective equipment was a crucial component for protection and contact precaution. Following hypoxia, effective oxygen therapy is administered right away. When necessary, under the right circumstances, nasal high-flow oxygen therapy, non-invasive ventilation, lung-protective breathing methods, and prone positioning can be used. Children with SARS-CoV-2/COVID-19 may benefit from physiotherapy interventions with a focus on ventilatory management, airway clearance procedures, early activities, and mobilization.

Chest physiotherapy for mechanically ventilated children: a survey of current UK practice

OBJECTIVES

Chest physiotherapy is a treatment option for mechanically ventilated children. However, there is a lack of consensus regarding its value and informal discussions suggest variation in practice. This study describes chest physiotherapy practices for mechanically ventilated children in the UK and explores clinical decision making related to its delivery.

DESIGN

Cross-sectional study, using an anonymous, electronic survey.

PARTICIPANTS

Qualified physiotherapists working in UK NHS paediatric intensive care units (PICUs).

RESULTS

The response rate was 61% (72/118), this included physiotherapists from 26/27 (96%) PICUs. All participants reported using manual hyperinflations and position changes 'always' or 'often'. Variation in practice was evident for some techniques, including Metaneb® and percussion. DNase (99%, 71/72) and hypertonic saline (90%, 65/72) were the most frequently used mucoactives: 91% (59/65) of physiotherapists reported only nebulising hypertonic saline and 69% (49/71) use both nebulised and instilled DNase. Use and delivery of N-acetylcysteine was inconsistent (nebulised only 55%, 26/47; instilled only 15%, 7/47; both 30%, 14/47). Chest physiotherapy was most commonly delivered with a nurse (67%, 48/72). Clinical decision making processes were comparable between physiotherapists and encompassed three main elements: individual patient assessment, involvement of the multidisciplinary team, and risk versus benefit analysis.

CONCLUSIONS

A range of chest physiotherapy treatments and adjuncts were used with ventilated children. Variation was apparent and may be due to individual preferences of those training staff or local policies. Pragmatic, interventional studies are required to determine best practice. Further exploration is necessary to understand the variation in practice and intricacies of decision making.

Immediate effects of manual hyperinflation on cardiorespiratory function and sputum clearance in mechanically ventilated pediatric patients: A randomized crossover trial

Background:

In developing countries, lower respiratory tract infection is a major cause of death in children, with severely ill patients being admitted to the critical-care unit. While physical therapists commonly use the manual hyperinflation (MHI) technique for secretion mass clearance in critical-care patients, its efficacy has not been determined in pediatric patients.

Objective:

This study investigated the effects of MHI on secretion mass clearance and cardiorespiratory responses in pediatric patients undergoing mechanical ventilation.

Methods:

A total of 12 intubated and mechanically ventilated pediatric patients were included in this study. At the same time of the day, the patients received two randomly ordered physical therapy treatments (MHI with suction and suction alone) from a trained physical therapist, with a washout period of 4 h provided between interventions.

Results:

The MHI treatment increased the tidal volume [Vt; 1.2 mL/kg (95% CI, 0.8–1.5)] and static lung compliance [Cstat; 3.7 mL/cmH₂O (95% CI, 2.6–4.8)] immediately post-intervention compared with the baseline (p<0.05). Moreover, the MHI with suction induced higher Vt [1.4 mL/kg (95% CI, 0.8–2.1)] and Cstat [3.4 mL/cmH₂O (95% CI, 2.1–4.7)] compared with the suction-alone intervention. In addition, the secretion mass [0.7 g (95% CI, 0.6–0.8)] was greater in MHI with suction compared with suction alone (p<0.05). However, there was no difference in peak inspiratory pressure, mean airway pressure, respiratory rate, heart rate, blood pressure, mean arterial blood pressure or oxygen saturation (p>0.05) between interventions.

Conclusions:

MHI can improve Vt, Cstat and secretion mass without inducing adverse hemodynamic effects upon the pediatric patients requiring mechanical ventilation.

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 in the Pediatric Intensive Care Unit

Despite widespread practice, there is very little, high-level evidence supporting the indications for and effectiveness of cardiopulmonary/chest physiotherapy (CPT) in critically ill infants and children. Conversely, most studies highlight the detrimental effects or lack of effect of different manual modalities. Conventional CPT should not be a routine intervention in the pediatric intensive care unit, but can be considered when obstructive secretions are present which impact on lung mechanics and/or gaseous exchange and/or where there is the potential for long-term complications. Techniques such as positioning, early mobilization, and rehabilitation have been shown to be beneficial in adult intensive care patients; however, little attention has been paid to this important area of practice in pediatric intensive care units. This article presents a narrative review of chest physiotherapy in pediatric critical illness, including effects, indications, precautions, and specific treatment modalities and techniques.

What is the role of the physiotherapist in paediatric intensive care units? A systematic review of the evidence for respiratory and rehabilitation interventions for mechanically ventilated patients

BACKGROUND

Physiotherapy in intensive care units (ICU) has traditionally focussed on the respiratory management of mechanically ventilated patients. Gradually, focus has shifted to include rehabilitation in adult ICUs, though evidence of a similar shift in the paediatric ICU (PICU) is limited.

OBJECTIVES

Review the evidence to determine the role of physiotherapists in the management of mechanically ventilated patients in PICU.

DATA SOURCES

A search was conducted of: PEDro, CINAHL, Medline, PubMed and the Cochrane Library.

ELIGIBILITY CRITERIA

Studies involving PICU patients who received physiotherapy while invasively ventilated were included in this review. Those involving neonatal or adult ICU patients, or patients on non-invasive or long-term ventilation, were not included in the study.

STUDY APPRAISAL

All articles were critically appraised by two reviewers and results were analysed descriptively.

RESULTS

Six studies on chest physiotherapy (CPT) met the selection criteria. Results support the use of the expiratory flow increase technique and CPT, especially manual hyperinflation and vibrations, for secretion clearance. Evidence does not support the routine use of either CPT or suction alone. No studies investigating rehabilitation in PICU met selection criteria.

LIMITATIONS

A lack of high level evidence was available to inform this review.

CONCLUSION

Evidence indicates that CPT is still the focus of physiotherapy intervention in PICU for mechanically ventilated patients, and supports its use for secretion clearance in this setting. PROSPERO register for systematic reviews (registration no. CRD42014009582).
