Introduction

Critical care is the specialised care of patients whose conditions are life-threatening and who require comprehensive care and constant monitoring, usually in intensive care units (ICUs).

Critically ill patients frequently suffer long-term physical and psychological complications. They are on long term mechanical ventilation and as a result ,25% display significant muscle weakness, and approximately 90% of long-term ICU survivors will have ongoing muscle weakness. Prolonged stays in the intensive care unit are also associated with impaired quality of life, functional decline and increased morbidity, mortality, cost of care and length of hospital stay.

Therefore, they require a multidisciplinary team in critical care who are uniquely qualified with skills and expertise to work with the assessment and management of respiratory complications, physical deconditioning, and neuromuscular and musculoskeletal conditions.

Physiotherapy treatment as part of a multi-disciplinary approach to care is integral in promoting lung function, reducing the incidence of ventilator-associated pneumonia, facilitating weaning and promoting safe and early discharge from the intensive care unit.

Physiotherapy rehabilitation in ICU

Physiotherapy is an important intervention that prevents and mitigates adverse effects of prolonged bed rest and mechanical ventilation during critical illness. Rehabilitation delivered by the physiotherapist is tailored to patient needs and depends on conscious state, psychological status and physical strength of the patient. It incorporates any active and passive therapy that promotes movement and includes mobilisation. Early progressive physiotherapy, with a focus on mobility and walking whilst ventilated, is essential in minimising functional decline. 

Physiotherapist works to maintain and improve respiration and cardiac functions and later on aid in rehabilitation.

How do physiotherapists do this?

Short term Goals:

• Early activity - Both passive and active to maintain integrity of musculoskeletal system
• Positioning patients: To allow gravity to help sputum drain from the lungs.
• Manual techniques such as shaking and vibrations: These are applied to the ribs to try to loosen and clear the sputum.
• Suction: By placing a small tube into the lungs to suck out the excess sputum.
• They play a vital role in weaning a patient off ventilation.

Long term:

• They plan an extensive rehabilitation programme to integrate and re-initiate the patient into society.
• They set goals in conjunction with the medical team to rehabilitate the patient.

Rehabilitation goals are set in communication ith the patient, patient's family and the medical team and are divided into short, medium or long term and change throughout the patient's recovery from critical illness. They can be physical as well as psychological but are concerned with functional needs of the patient. Goals will need to be achievable and based on regular patient assessment of physical and non-physical consequences of the critical illness throughout their recovery and change according to the progress.

Adverse effects of ICU stay:

• Physical Inactivity leading to muscular atrophy and generalized weakness
• Diaphragmatic weakness due to prolonged mechanical ventilation
• Pressure Ulcers
• compromised cardiac and respiratory function
• deep vein thrombosis
• infections

Physiotherapy Techniques in ICU :

Respiratory Physiotherapy :

It basically works with clearing the airways of the patients and maintaining and improving the integrity of the respiratory system.

It includes:

• positioning,
• education,
• manual and ventilator hyperinflation,
• weaning from mechanical ventilation,
• non-invasive ventilation,
• percussion, vibration, suctioning,
• respiratory muscle strengthening,
• breathing exercises and mobilisation

Rehabilitation:

Early Mobilisation with a focus on returning to funcional activities helps in reducing hospital stay and minimize functional decline.

The goals are mapped out based on patient's physical, psychological status. During his critical care unit stay physiotherapists should perform a short clinical assessment

• to determine the patient's risk of developing physical and non-physical morbidity.
• to identify their current rehabilitation needs
• For patients at risk, start rehabilitation as early as clinically possible which should include:

1. measures to prevent avoidable physical and non-physical morbidity,

2. nutrition support

3.an individualised, structured rehabilitation programme with frequent follow-up reviews. The details of the structured rehabilitation programme and the reviews should be collated and documented in the patient's clinical records.

Impact of Physiotherapy

Early intervention by physiotherapists in the ICU helps

• reduce the patient's stay in the ICU and overall hospital stay.
• prevent ICU related complications
• to improve function and quality of life in long term

Studies have shown that Physiotherapy intervention in Critical care has helped reduce the mortality rate by 25%.
