Proning

When patients face severe respiratory failure, doctors use a lifesaving method called prone positioning. This technique has become key during the COVID-19 pandemic. It helps improve oxygen levels in critically ill patients.

Proning involves turning patients from their backs to their stomachs. This allows for better lung function and oxygenation. By changing the body’s position, it reduces lung pressure and improves gas exchange.

This simple action boosts lung function and survival chances in patients with severe respiratory issues. As the world fights COVID-19, prone positioning is a critical tool in critical care.

What is Proning and How Does it Work?

Proning, or prone positioning, is a method used in critical care to help patients breathe better. It involves turning a patient onto their stomach. This helps improve lung function and can lead to better health outcomes.

Definition of Proning

Prone positioning means placing a patient on their stomach. Their head is turned to the side, and arms are by their body or above their head. Pillows support the chest and pelvis. This position helps the lungs expand better, which is important.

Physiological Effects of Proning on the Lungs

Prone positioning has many benefits for the lungs. It helps the lungs expand, which improves breathing. This is because the back of the lungs can expand more when a person is on their stomach.

It also helps clear out airway secretions. This reduces the chance of lung infections and breathing problems. Prone positioning is very helpful for patients with severe breathing issues, like those with ARDS.

Indications for Proning in Critical Care

In critical care, proning helps patients with severe respiratory distress. It’s used when usual treatments don’t work well. The main reasons for proning are acute respiratory distress syndrome (ARDS), severe hypoxemia, and hard-to-treat respiratory failure.

Acute Respiratory Distress Syndrome (ARDS)

ARDS is a serious lung condition. It causes inflammation and fluid buildup in the lungs, making it hard to breathe. Patients with ARDS often need a lot of oxygen and ventilation but may not get better.

Proning can help by spreading air and blood flow more evenly in the lungs. This can improve oxygen levels and survival chances for those with moderate to severe ARDS.

Severe Hypoxemia

Severe hypoxemia means not enough oxygen in the blood. It’s a big problem in critical care. When usual treatments don’t work, proning can help.

It reduces problems with air and blood flow in the lungs. This can help get more oxygen to important organs. It can also prevent damage to other parts of the body.

Refractory Respiratory Failure

Refractory respiratory failure means the lungs keep getting worse despite all treatments. Proning can be a last resort to help.

It makes lung function better and lowers the risk of lung damage from the ventilator. This can stabilize patients and give other treatments a chance to work.

Deciding to use proning should involve a team of doctors and nurses. They consider the patient’s health, other conditions, and the risks and benefits of proning. It’s important to watch patients closely to make sure proning is safe and effective.

Ventilator Settings and Adjustments During Proning

When using proning for critically ill patients, it’s key to adjust ventilator settings. This ensures the best results. Changing settings like tidal volume, positive end-expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) is important. It helps make proning safer and more effective.

Keeping tidal volume low, around 6-8 mL/kg of ideal body weight, is a good strategy. This reduces lung damage. Also, PEEP should be set to keep lungs open, usually between 10-16 cmH2O for severe ARDS.

Adjusting FiO2 to keep oxygen saturation between 88-95% or PaO2 at 55-80 mmHg is vital. It’s a balance between enough oxygen and avoiding too much. Monitoring lung function helps adjust settings and see how the patient is doing.

The following table summarizes the recommended ventilator settings during proning:

These settings are a starting point and may need to change based on the patient’s response. A team effort from doctors, nurses, and respiratory therapists is key. This ensures the best care for critically ill patients during proning.

Proning Protocol and Patient Positioning

Creating a solid proning protocol is key for safe and effective prone positioning in critical care. It’s important to prepare well, choose the right equipment, and follow a systematic approach to positioning patients.

Preparation and Equipment

Before starting a proning session, make sure you have all the needed equipment. Also, ensure the healthcare team knows the proning protocol well. Important equipment includes:

• Specialized proning beds or mattresses to reduce pressure ulcer risk
• Pillows and aids to support the patient’s head, chest, and pelvis
• Foam dressings or protective padding to prevent skin breakdown
• Monitoring devices to track vital signs and oxygenation

Step-by-Step Guide to Prone Positioning

Following a systematic approach to positioning is vital for safety and best results. Here’s a typical proning protocol:

1. Check if the patient is suitable for prone positioning based on clinical criteria and contraindications.
2. Get ready the necessary equipment and brief the healthcare team on their roles and responsibilities.
3. Give sedation and analgesia as needed for patient comfort and compliance.
4. Disconnect any non-essential lines or tubes and secure essential ones to prevent dislodgement.
5. With 4-5 trained personnel, carefully turn the patient onto their stomach, ensuring proper alignment of the head, neck, and spine.
6. Position the patient’s arms at a 90-degree angle to the body, alternating the direction of the head to prevent nerve compression.
7. Place pillows or foam supports under the chest and pelvis to allow for abdominal excursion and prevent pressure ulcers.
8. Reassess the patient’s vital signs, oxygenation, and skin integrity regularly throughout the proning session.

Duration and Frequency of Proning Sessions

The best duration and frequency of proning sessions vary based on the patient’s condition and response. Generally, sessions should last at least 16 hours a day. Patients are returned to the supine position for nursing care and assessments. The number of sessions needed depends on the patient’s clinical progress and the severity of their respiratory distress. In some cases, patients may need multiple sessions over several days to see improvements in oxygenation and lung function.

By sticking to a well-designed proning protocol and ensuring proper patient positioning, healthcare teams can effectively use this life-saving intervention. It’s important to monitor the patient’s response to proning and have a multidisciplinary approach to care. This ensures the best outcomes for critically ill patients with severe respiratory failure.

Monitoring and Assessment During Proning

It’s very important to watch closely when using prone positioning in critical care. Healthcare workers need to keep an eye on the patient’s vital signs and oxygenation levels. This helps spot any changes or complications early on.

Vital Signs and Oxygenation

While the patient is in the prone position, their heart rate, blood pressure, breathing rate, and oxygen levels should be checked often. If these signs change a lot, it might mean the patient needs some adjustments or help. The goal is to keep the heart and lungs working well and to improve oxygen levels.

Complications and Side Effects

Proning can be very helpful, but it also has some risks. One big problem is getting pressure ulcers, which can happen on the face, chest, and pelvis. To avoid this, healthcare teams use special mattresses or cushions to reduce pressure.

Other possible problems with proning include:

By being careful and quick to act, healthcare teams can make proning safer and more effective for patients.

Proning in the Context of COVID-19 Treatment

The COVID-19 pandemic has shown how important proning is for treating severe SARS-CoV-2 cases. The virus mainly attacks the lungs, causing severe breathing problems. Healthcare workers use proning to help patients breathe better and live longer.

Effectiveness of Proning for COVID-19 Patients

Many studies have shown proning’s benefits for COVID-19 patients:

These studies confirm that proning helps COVID-19 patients breathe better and survive longer.

Challenges and Considerations in the Pandemic Setting

Using proning during the COVID-19 pandemic is tough. Hospitals are overwhelmed with patients and resources are scarce. Proning needs more staff, training, and gear, which is hard to get.

Also, SARS-CoV-2 is very contagious, making it hard to keep patients safe. But, healthcare teams have found ways to make proning work. They’ve created clear plans, worked together, and even used proning in non-ICU areas. This has helped more patients get this critical treatment during the pandemic.

Proning Outside the ICU: Expanding Access to Life-Saving Care

Proning has long been used in ICUs for very sick patients. Now, there’s a push to use it in non-ICU settings and resource-limited environments. This move aims to make this care more accessible and save more lives.

Awake proning is a new method. It involves patients who can understand and follow directions lying on their stomachs. This method helps those with breathing problems, even without machines to help them breathe. It can be done in regular hospital wards, emergency rooms, and even at home, helping in resource-limited environments.

Starting proning early is vital, whether in ICUs or other places. Early use can stop the disease from getting worse. This is very important in places with fewer advanced care options.

To use proning outside ICUs, healthcare workers need training and clear rules. Teams of nurses, respiratory therapists, and physical therapists are key. They work together to make sure proning is done safely and well.

The fight against COVID-19 shows the need for more access to proning. By using it in more places, we can help more people and ease the load on critical care units.

Multidisciplinary Team Approach to Proning

Effective proning needs a multidisciplinary team of healthcare pros working together. Each team member is key to the success of proning, from choosing patients to watching over them during the process.

Roles and Responsibilities of Healthcare Professionals

The team usually includes:

• Nurses: Nurses lead in patient care, watching vital signs, giving meds, and keeping patients comfy. They also help position the patient and prevent problems.
• Respiratory therapists: These therapists manage the ventilator, check oxygen levels, and adjust airways as needed. Their skills are vital for proning’s benefits.
• Physicians: Doctors guide the treatment plan, decide when to start and stop proning, and handle any issues that come up.
• Physical therapists: Physical therapists assist in positioning, moving patients, and preventing bed sores and other issues from too much sitting.

Collaboration and Communication

Good collaboration and communication among the team are key for proning success. Regular meetings, clear plans, and open talk ensure everyone is working together towards the same goals.

Nurses and respiratory therapists work together to watch how patients react to proning. They adjust as needed and quickly address any issues. They also keep doctors updated on patient progress and any changes.

By building a team culture of teamwork and open talk, the multidisciplinary team can give the best care to critically ill patients. This improves outcomes and saves lives.
