It is common practice for hospitals and surgical facilities to require patients to remove nail polish, acrylic nails, gel nails, and other nail enhancements before surgery. This is primarily because these nail products can interfere with the accuracy of vital sign monitoring devices such as the pulse oximeter, which is typically attached to a finger to measure oxygen levels in the blood. Nail polish, especially dark or opaque polishes, can block or distort the light beams used by the pulse oximeter to gauge blood oxygen levels. Additionally, nail polish and artificial nails can chip or peel during surgery, potentially contaminating sterile surfaces and increasing the risk of infection. Therefore, removing nail polish and acrylic nails before surgery is essential for ensuring patient safety, accurate monitoring, and maintaining a sterile surgical environment.

Pulse oximeters need bare nails to monitor oxygen levels in the blood
It is common practice for hospitals and surgical offices to advise patients to remove nail polish, acrylic nails, and gel nails before surgery. This is because pulse oximeters, one of the most important monitoring devices for patient safety, need bare nails to monitor oxygen levels in the blood accurately.
Pulse oximeters are small devices that clip onto a patient's finger to measure oxygen levels in the blood. They work by passing light beams or red light through the tissue of the fingertip. The device then gauges blood oxygen levels based on how these light beams are reflected back. If these light beams are blocked or distorted by thick acrylics, dark or opaque polish, or multiple layers of nail polish, it can be harder for the device to get an accurate reading.
Nail polish may reduce the effectiveness of the pulse oximeter, which is crucial for monitoring the oxygenation of a patient's haemoglobin during surgery. The nail bed is one of the best places to detect cyanosis, a bluish discolouration caused by low oxygen levels. Therefore, it is important to remove nail polish, acrylic nails, gel nails, and other nail enhancements before surgery to ensure that the pulse oximeter can accurately monitor oxygen levels in the blood.
In certain cases, some surgical facilities permit the use of clear, liquid-fast-drying, and chip-resistant nail polish during surgery. These types of nail polish allow for better visibility of the nail bed while still providing a professional appearance. However, it is essential to consult with your surgeon before your surgery to confirm their specific requirements.
If you forget to remove your nail polish before surgery, inform your surgical team. They may offer solutions, such as removing it for you or using alternative monitoring sites that provide accurate measurements during the procedure.

Dark nail polish may prevent the detection of low oxygen levels
The nail bed is one of the best places to detect cyanosis, which is a bluish discolouration caused by low oxygen levels. Dark nail polish can interfere with the ability to detect this discolouration. Therefore, it is recommended that patients remove nail polish, especially dark nail polish, before surgery to ensure accurate monitoring of oxygen levels and to maintain a sterile environment.
It is important to note that some surgical facilities may permit the use of clear, liquid-fast drying, and chip-resistant nail polish during surgery. These types of polish allow for better visibility of the nail bed while still providing a professional appearance. However, it is always best to consult with a surgeon before the procedure to confirm their specific requirements.
If a patient forgets to remove their nail polish before surgery, they should inform the surgical team. The team may be able to remove the nail polish or use alternative monitoring sites that are not affected by nail polish.

Long nails may hold bacteria and germs, increasing the risk of infection
It is important to remove nail polish before surgery to ensure a sterile environment and reduce the risk of infection. Long nails, which are common among those who use nail polish, may hold bacteria and germs, increasing the risk of infection.
The surgical environment requires utmost cleanliness to prevent the spread of harmful pathogens. Nail polish, artificial nails, and nail extensions can chip or peel, leading to the potential contamination of sterile surfaces. This can compromise the sterility of the operating room and increase the risk of infection for the patient.
The pulse oximeter is a vital monitoring device used during surgery to measure oxygen levels in the blood. It is attached to the patient's finger or earlobe and uses light beams to gauge blood oxygenation. Nail polish, especially dark or opaque polish, can interfere with the accuracy of the pulse oximeter by blocking or distorting the light beams. This can make it difficult for the medical team to ensure the patient is receiving adequate oxygen during the operation.
In some cases, the medical team might have to try multiple fingers or even an earlobe to obtain accurate readings, causing unnecessary delays and potential confusion. Removing nail polish before surgery ensures that the pulse oximeter can be placed on the finger, allowing for efficient and effective monitoring of the patient's oxygen levels.
Additionally, keeping nails bare during the recovery period is important. This allows the surgical team to monitor the nail bed for any signs of cyanosis, a bluish discoloration caused by low oxygen levels. By keeping nails polish-free, patients can ensure that any changes in nail color are easily detectable, providing valuable information about their oxygenation status.

Nail polish may chip or peel, leading to the contamination of sterile surfaces
It is important to remove nail polish before surgery because it may chip or peel, leading to the contamination of sterile surfaces. This is a significant concern in surgical environments, which require utmost cleanliness to minimize the risk of infection. Contamination of sterile surfaces can have severe consequences for patient safety.
Nail polish, especially darker or opaque shades, can interfere with the accuracy of pulse oximeters, which are vital monitoring devices that measure oxygen levels in the blood. These devices use light beams that pass through the fingertip, and if these light beams are blocked or distorted by nail polish, it can be harder to get an accurate reading. The nail bed is one of the best places to detect cyanosis, a bluish discoloration caused by low oxygen levels. Therefore, it is crucial to remove nail polish before surgery to ensure accurate monitoring of the patient's oxygen levels.
In some cases, the medical team might have to try multiple fingers or even an earlobe to find an alternative monitoring site, causing unnecessary delays and potential confusion. Removing nail polish before surgery ensures that the pulse oximeter can be placed on the finger, providing accurate and efficient monitoring of the patient's vital signs.
It is recommended to remove nail polish the night before or the morning of the surgery. If nail polish is forgotten to be removed, the patient should inform their surgical team, who may offer solutions or use alternative monitoring methods.

Hospitals usually advise patients to remove nail polish before surgery
Another critical reason for removing nail products is to ensure accurate monitoring of vital signs during surgery. The pulse oximeter, a small device that clips onto a finger, is used to measure oxygen levels in the blood by passing light beams through the fingertip. Nail polish, especially dark or opaque colours, can block or distort these light beams, affecting the accuracy of the reading. The nail bed is also an important area for detecting cyanosis, a bluish discolouration caused by low oxygen levels.
Some surgical facilities may permit specific types of nail polish, such as clear, liquid-fast-drying, and chip-resistant varieties, as they allow better visibility of the nail bed while providing a professional appearance. However, it is always best to consult with the surgeon beforehand to confirm their specific requirements and avoid potential cancellations or delays.
To prepare for surgery, it is recommended to remove nail polish the night before or the morning of the procedure. This allows for a careful and stress-free process, giving time for any minor issues, such as dry or irritated nail beds, to recover naturally before surgery. It is also essential to ensure that there is no leftover nail paint or treatment remaining on the nails.
