Understanding in what position should you place a person who is unconscious when performing oral hygiene, prone, supine, side-lying, Trendelenburg? The Definitive Guide to Safe Patient Care

5 min read

According to the American Dental Association, unconscious patients are at a higher risk of developing aspiration pneumonia due to poor oral hygiene. Knowing in what position should you place a person who is unconscious when performing oral hygiene is the most crucial step for caregiver and patient safety, directly mitigating the risk of fluid entering the lungs.

Quick Summary

For safety and to prevent aspiration during care, an unconscious person should be placed in a side-lying position with their head turned to the side, allowing fluids to drain from the mouth. Improper positions like supine, prone, or Trendelenburg can increase the risk of choking and aspiration.

Key Points

  • Side-Lying is Safest: The side-lying or lateral position is the correct choice to prevent aspiration during oral care for an unconscious patient by using gravity to facilitate drainage.

  • Head Turned to Side: Turning the patient's head to the side is essential, allowing fluids and secretions to exit the mouth rather than collect at the back of the throat.

  • Aspiration Prevention is Key: The main goal is to prevent aspiration pneumonia, a serious lung infection caused by inhaling oral bacteria, which unconscious patients are highly susceptible to.

  • Avoid Supine and Trendelenburg: Placing the patient flat on their back (supine) or with their head down (Trendelenburg) drastically increases the risk of aspiration and is unsafe for this procedure.

  • Use Appropriate Tools: Always use soft-bristle brushes or oral swabs with minimal fluid. Have a padded tongue blade and suction equipment ready to ensure the patient's safety.

The Importance of Oral Hygiene for Unconscious Individuals

Proper oral hygiene is a critical component of care for individuals who are unconscious or have a reduced level of consciousness. For these patients, regular and thorough mouth care is essential for preventing serious complications, including aspiration pneumonia. Aspiration pneumonia occurs when bacteria from the mouth are inhaled into the lungs, leading to a severe and potentially life-threatening infection. In a state of unconsciousness, a person's gag and swallow reflexes are compromised, making them highly susceptible to this risk. Therefore, understanding and executing safe oral care practices is not just about cleanliness; it is a fundamental aspect of life-sustaining care. The primary principle guiding this procedure is to ensure that no fluids or debris enter the patient's airway, and this begins with correct positioning.

Why Positioning is the First Step to Safety

Patient positioning is the single most important factor when performing oral hygiene on an unconscious person. An incorrect position, such as lying on the back (supine), allows gravity to pull fluids and saliva toward the throat and lungs, creating a direct pathway for aspiration. Other positions present their own set of dangers, making careful selection paramount. The side-lying, or lateral, position is widely recognized as the safest choice by medical professionals because it leverages gravity to work in your favor. With the patient on their side, any fluids used during the cleaning process will naturally drain out of the mouth, away from the airway. This simple but critical action can significantly reduce the risk of a serious respiratory event.

The Safest Choice: The Side-Lying Position

When considering in what position should you place a person who is unconscious when performing oral hygiene, the side-lying or lateral position is the correct answer. This method involves positioning the patient on their side, with their head slightly turned toward you. This posture is not only for gravity's benefit but also offers the caregiver better access and control throughout the procedure. For added stability and to maintain the position, pillows can be used to support the patient's back and to position the head and neck correctly. Some variations, such as the Sims' position, a semi-prone side-lying position, can also be utilized, but the principle of fluid drainage remains the same.

How to Perform Oral Care in the Side-Lying Position

Following a clear procedure is vital to ensure patient safety and comfort.

  1. Gather Your Supplies: Collect all necessary items before beginning the procedure. This includes a basin, a soft-bristle toothbrush or oral swabs (also called toothettes), a small amount of water or oral rinse, towels, lip lubricant, and a padded tongue blade.
  2. Position the Patient: Explain the procedure to the patient, even if they are unconscious, as they may still be able to hear. Raise the bed to a comfortable working height and lower the side rail. Gently roll the patient onto their side, facing you. Place a towel under their chin and a basin near their cheek to catch any fluid. Ensure the head is turned enough for drainage.
  3. Prepare the Mouth: Use the padded tongue blade to gently open the patient's mouth. This is a crucial step to protect your fingers from being bitten if a reflex is triggered. Never force the mouth open or use your fingers.
  4. Clean the Oral Cavity: Using a small amount of cleaning solution on a soft toothbrush or oral swab, gently clean the teeth, gums, tongue, and roof of the mouth. Focus on one quadrant at a time, being careful to avoid stimulating the gag reflex. For patients with dentures, remove them first and clean separately.
  5. Moisten and Lubricate: Use a fresh, moistened swab to clear any remaining debris. Apply a water-based lip lubricant to keep the patient's lips from drying out.
  6. Ensure Proper Drainage: Throughout the process, ensure all fluids drain into the basin and that the patient's airway remains clear. After completion, pat the mouth and lips dry and reposition the patient for comfort.

Comparing Patient Positions for Oral Care

Position Description Risks for Unconscious Patient Benefits for Oral Care Safest for Oral Hygiene?
Side-Lying Patient is on their side, with head turned. Minimal, as gravity aids drainage. Prevents aspiration, allows for fluid drainage, better caregiver access. Yes
Supine Patient is flat on their back, facing upwards. High risk of aspiration due to pooling fluids and saliva. Provides full access to the face and mouth, but at a high safety risk. No
Prone Patient is lying on their stomach. Not suitable; blocks access to the mouth and can cause respiratory distress. Not a viable option for this procedure. No
Trendelenburg Patient's head is lower than their feet. Extremely high risk of aspiration; gravity pulls all fluids into the lungs. None; this is a dangerous and inappropriate position. No

Critical Tools and Preparations

  • Oral Swabs (Toothettes): These are essential for cleaning the mouth without introducing large amounts of liquid. They can be moistened with a small amount of water or mouth rinse. It is a common mistake to use lemon glycerin swabs, which can be irritating and acidic.
  • Suction Equipment: A portable or wall-mounted suction device should always be nearby and ready for use in case any fluid is accidentally aspirated. Regular, gentle suctioning during the procedure can also aid in managing secretions.
  • Padded Tongue Blade: Used to gently separate the patient's teeth and maintain a safe opening. Crucially, this prevents the caregiver's fingers from being bitten and provides a safe way to hold the mouth open without causing injury.
  • Water-Based Lip Lubricant: The lips and mouth of an unconscious patient can become very dry. Applying a gentle, water-based lubricant at the end of the procedure helps maintain moisture and prevent chapping.

Avoiding the Wrong Positions

Understanding why certain positions are dangerous is as important as knowing the right one. Placing an unconscious patient in a supine position is a grave error. The risk of fluids being accidentally aspirated into the lungs is extremely high and can lead to immediate respiratory distress. The Trendelenburg position, where the head is lower than the body, is even more dangerous, as gravity will directly pull any liquid from the mouth and throat straight into the trachea and lungs. The prone position is not only unsuitable for oral care but also poses a risk of suffocation and should never be used for this purpose.

Conclusion

Providing safe and effective oral hygiene for an unconscious patient requires a meticulous approach and an unwavering commitment to safety. The answer to in what position should you place a person who is unconscious when performing oral hygiene is unequivocally the side-lying position. This simple technique, combined with the right tools and attention to detail, can protect the patient from the severe and preventable complication of aspiration pneumonia. By adhering to these best practices, caregivers can provide high-quality care that not only maintains hygiene but also prioritizes the well-being and longevity of the patient. Continuous education on these techniques is a cornerstone of responsible and compassionate caregiving.

Frequently Asked Questions

The side-lying position is the best because it uses gravity to move saliva, rinse water, and other fluids out of the mouth and into a basin, rather than down the back of the throat where they could be aspirated into the lungs. This significantly reduces the risk of choking and aspiration pneumonia.

Aspiration pneumonia is a serious lung infection that occurs when bacteria from the mouth are inhaled into the lungs. Unconscious patients are at high risk because their natural gag and swallow reflexes are impaired, allowing oral secretions to easily enter their airway.

No, a powered toothbrush is not recommended as it could cause trauma to the mouth tissues and introduces more fluid than necessary. A soft-bristle manual toothbrush or a soft oral swab is preferred to gently clean the oral cavity.

Caregivers should have oral swabs (toothettes), a basin, a padded tongue blade, a small amount of clean water or oral rinse, towels, and a water-based lip lubricant. Suction equipment should also be readily available in case of an emergency.

If an unconscious patient appears to be choking, immediately stop the procedure, reposition the patient to ensure an open airway, and use suction to clear any fluid. Activate emergency medical services if the patient does not quickly recover or if breathing is severely compromised.

No, it is never acceptable to perform oral care on an unconscious patient in the supine position. This posture creates a high risk of fluids flowing directly into the lungs due to a lack of proper drainage and an impaired gag reflex.

For unconscious or unresponsive patients, oral care should be performed at a minimum of every two hours to prevent the buildup of bacteria and maintain oral health. This frequent care is critical for reducing the risk of aspiration pneumonia.
