Plain English Summary

Background and study aims
When a patient is in an intensive care unit (ICU), they may require need help breathing. This is often done using a process called intubation, in which a flexible plastic tube is passed down the throat into the windpipe in order to keep the airways open. The tube is then connected to a breathing machine which passes air into and out of the lungs (mechanical ventilation). When the patient has recovered enough for the tube to be removed (extubation), in some cases this is unsuccessful (extubation failure) and the tube needs to be put back in (reintubation). Extubation failure can lead to a long hospital stay, higher death rate, and increases the chance that the patient will need an operation called a tracheostomy (an opening created at the front of the neck so a tube can be inserted into the windpipe). Chest physiotherapy (CPT) can help to reduce the chance of this, as it prevents fluid from building up in the lungs which can lead to complications. However, few studies have been done looking at the relationship between CPT and extubation failure. The aim of this study is to investigate whether CPT reduces the rate of extubation failure.

Who can participate?
Adults admitted to the Landseed Hospital Intensive Care Unit who require mechanical ventilation for at least 48 hours.

What does the study involve?
Two groups of participants take part in this study. The first group of participants does not actively take part but are patients who previously received standard nursing care while in ICU in 2015. Their medical records are reviewed in order to assess the extubation failure rate and the amount successfully extubated (extubation outcomes). The second group is currently on ICU and takes part in a chest physiotherapy program. This consists of various training exercises aiming to strengthen the muscles involved in breathing, and the removal of mucous from the airways. Treatment takes place in 30-40 minute sessions once a day, five times a week, until the patient is discharged from ICU. At the end of the study, the extubation outcomes are compared between the groups to find out whether the treatment helped reduce the rate of extubation failure.

What are the possible benefits and risks of participating?
There are no direct benefits or risks involved to those participating in this study.

Patients requiring mechanical ventilation


Two groups of participants take part in this study.

Control group: Patients who previously received standard nursing care have their case notes from 2015 reviewed for extubation outcomes, mortality, hosptial transfers and clinic data (such as clinical diagnosis, Glasgow coma score, heart rate, blood pressure, respiratory rate, tidal volume,RSBI, length of stay, duration of mechanical ventilation and secretion volume). The results of this are then compared to the intervention group.

Intervention group: Participants take part in a a chest physiotherapy program, which consists of inspiratory muscle training, manual hyperinflation, chest wall mobilization, rib-cage compression, posture drainage, secretion removal, cough function training, extremity range of motion exercise.
Rib cage compression consists of producing mechanical force transferred through the chest wall into the airways during the expiratory phase for the purpose of increasing and redirecting air flow, for pulmonary re-expansion and airway clearance.
Manual hyperinflation was performed using a manual hyperinflation device with inspiratory pressure 40 cm H2O and FIO2 at 0.6, inducing a tidal volume increase and generating subsequent improvement in pulmonary compliance, inspiratory flow, and bronchial secretion clearance.
During implementation of the techniques, SpO2 , heart rate, breathing frequency, and mean arterial pressure were monitored to control the effects while the protocol was performed.
Early mobilization were also given by the physiotherapist according to patients’ conditions, vital signs, and clinical performance. These exercises started with sitting on the edge of the bed for moving their limbs, training for standing on their own, and moving off the bed to sit in a chair.
Treatment takes place in 30-40 minute sessions once a day, five times a week, and treatments were given until the patient was discharged from the ICU.
Extubation outcomes are determined according to observations by the attending physician.

Drug names

Primary outcome measures

Extubation outcomes are determined by the attending physician observations (taken from medical records for control participants):
1. Extubation failure rate, defiened as the need for reintubation within 72 hours after extubation
2. Extubation rate, is calculated as extubation failure participants divided by all participants

Secondary outcome measures

Rapid Shallow Breathing Index is measured using a handheld spirometer attached to the endotracheal tube while the patient breathes room air for one minute without any ventilator assistance in the intervention group, and taken from medical records for control participants.
