If you're booked in for surgery, you might be wondering if you can keep your gel nails. The short answer is no—it's important to remove gel nails and nail polish before a surgical procedure. This is because doctors and nurses need to be able to see your natural nails to check your circulation and monitor your oxygen levels. Nail polish can interfere with the accuracy of pulse oximeters, which are small devices that clip onto a finger to measure oxygen levels in the blood. In addition, artificial nails can introduce bacteria and fungi into the operating theatre environment, potentially causing post-surgical infections.

What You'll Learn

Gel nails can interfere with pulse oximetry
It is generally recommended that you remove gel nails before surgery. This is because gel nails can interfere with pulse oximetry, which is used to monitor your vital signs during surgery.
Pulse oximetry is a non-invasive method used to monitor a patient's vital signs during surgery. It involves the use of a pulse oximeter, a small device that clips onto a patient's finger to measure the oxygen levels in their blood. This measurement helps ensure that the patient is getting enough oxygen during the operation.
Gel nails, as well as acrylic nails and multiple layers of nail polish, can interfere with the accuracy of the pulse oximeter's reading. The sensor uses light beams that pass through the fingertip to gauge blood oxygen levels. If these light beams are blocked or distorted by thick or opaque nails, it can be harder for the device to get an accurate reading.
In some cases, medical staff may be able to use the patient's earlobe to get a reading. However, this is not always possible, and it can cause unnecessary delays and confusion. It is also important to note that, in addition to interfering with pulse oximetry, gel nails can also make it more difficult for medical staff to visually check the nail bed for circulation and overall health.
Therefore, it is generally advisable to remove gel nails before surgery to ensure accurate monitoring and to maintain the safety and sterility of the surgical environment.

Gel nails can affect the sterility of the operating room
In addition, gel nails can also make it difficult for surgeons to visually check the nail bed for circulation and overall health. While this may not be critical, surgeons prefer to avoid any unnecessary risks, and ensuring that natural nails are easily visible is one way to do this. Well-applied gel nails are usually safe, but there is still a small risk of bacterial or fungal growth underneath them, which can introduce extra bacteria or fungi into the operating room. Hospitals maintain strict hygiene standards to minimize the risk of infections, and removing gel nails before surgery helps maintain these standards.
Some surgical facilities may permit the use of clear, liquid-fast-drying, and chip-resistant nail polish during surgery, as this type of polish allows 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 and avoid any last-minute stress or delays. Overall, the potential impact of gel nails on the accuracy of medical devices and the sterility of the operating room means that they are generally not recommended for patients undergoing surgery.

Gel nails can make it difficult to visually check the nail bed
It is important to prepare your nails before surgery. This includes removing any nail products, such as gel nails, and ensuring there is no leftover nail paint or treatment on your nails. This is because gel nails can interfere with the ability to visually check the nail bed, which is an important way to monitor circulation levels during surgery.
The nail bed can provide important information about a patient's circulation and oxygenation. Doctors need to be able to notice any changes in colour in the nails, which could indicate low oxygen levels or poor circulation. This is particularly important during complex procedures, such as breast augmentation, where surgeons want to avoid any unnecessary risks.
Gel nails can also interfere with the accuracy of a pulse oximeter, a device that measures oxygen levels in the blood by attaching to a patient's finger or earlobe. If the light beams used by the device are blocked or distorted by thick or opaque gel nails, it may be harder to get an accurate reading. In some cases, medical staff may need to try multiple fingers or an earlobe, causing unnecessary delays.
Therefore, it is generally recommended to remove gel nails before surgery to ensure a safe and sterile surgical environment and allow for effective monitoring of the patient's vital signs. While toenail polish does not usually interfere with surgical monitoring, it is always best to consult with a surgeon about their specific requirements.

Gel nails may need to be removed before surgery to avoid delays
One of the critical reasons why gel nails are typically not recommended during surgery is their potential interference with medical monitoring devices, such as the pulse oximeter. This device is used to monitor your vital signs and oxygen levels in the blood by attaching a small clip to your finger or earlobe. The pulse oximeter uses light beams that pass through the fingertip to gauge blood oxygen levels accurately. However, if you have gel nails, they may block or distort these light beams, making it challenging for the device to obtain precise readings. In such cases, the medical team might need to try multiple fingers or even resort to using the earlobe, causing unnecessary delays and potential confusion.
Additionally, gel nails can hinder the medical team's ability to monitor your circulation levels during surgery. Assessing the colour of your nail bed provides valuable information about your blood circulation and oxygenation. Gel nails can obstruct visual checks, adding an unnecessary risk that surgeons prefer to avoid. Ensuring that your natural nails are visible gives the medical team one less variable to worry about.
Furthermore, gel nails can introduce bacterial or fungal growth, which can compromise the sterile surgical environment. Hospitals maintain stringent hygiene standards to minimise the risk of infections, and removing gel nails before surgery helps reduce the chances of introducing additional bacteria or fungi into the operating theatre.
While there may be conflicting advice from different medical professionals, it is generally advisable to remove gel nails before surgery. This proactive approach ensures a successful and complication-free surgical experience, contributing to your overall health and well-being.

Toenail polish is generally allowed, but it's best to consult a surgeon
Nail polish, especially opaque or dark colours, can interfere with the accuracy of the pulse oximeter readings. The sensor uses light beams that pass through the fingertip to gauge blood oxygen levels. If these light beams are blocked or distorted by thick or dark nail polish, it can be harder for the device to get an accurate reading. In some cases, the medical team might have to try multiple fingers or even an earlobe, causing unnecessary delays and potential confusion.
Additionally, the colour of the nail bed can provide important clues about your blood circulation and oxygenation. Toenail polish can make visual checks of the nail bed more difficult, and while this may not be critical, surgeons often prefer to avoid any unnecessary risk. Ensuring that your natural nails are easily visible gives them one less variable to worry about.
Furthermore, there are hygiene considerations to take into account. Artificial nails and gel polish can harbour bacteria and fungi that are not appropriately removed by standard handwashing techniques. Removing artificial nails and gel polish before surgery helps reduce the chance of introducing extra bacteria or fungi into the operating theatre environment.

Frequently asked questions
No, it is not advisable to wear gel nails during surgery. Gel nails can interfere with pulse oximetry and hygiene standards.
During surgery, the medical team needs to closely monitor your vital signs. One way of doing this is by using a pulse oximeter, a small device that clips onto a finger to measure the oxygen levels in your blood. Gel nails can interfere with the accuracy of this reading.
If you arrive with gel nails on the day of your surgery, the hospital staff may try to remove one nail or reposition the sensor to get a good reading. This could cause delays or inconvenience.
