Many people wonder if they need to remove their nails before surgery. While it may seem like a purely cosmetic concern, removing artificial nails and nail polish is an important step in ensuring patient safety and the smooth running of a procedure. This is because a pulse oximeter, a device that monitors oxygen levels in the blood, is usually clipped onto a patient's finger during surgery. Nail polish, artificial nails, and gel nails can interfere with the accuracy of the pulse oximeter's readings, as it uses light beams to gauge blood oxygen levels. Additionally, artificial nails and long nails can increase the risk of bacterial or fungal growth and contamination of sterile surfaces. Therefore, it is generally recommended to remove nails and nail polish before surgery, but specific policies and recommendations may vary between hospitals and surgeons.

What You'll Learn
Hospitals may cancel surgery if nails are not bare
Hospitals prioritize patient safety and the smooth running of procedures. Before surgery, they advise patients to remove nail polish, acrylic nails, gel nails, and other nail enhancements. This is because nail polish and artificial nails can interfere with the accuracy of pulse oximeters, which are vital monitoring devices that measure oxygen levels in the blood by sending light beams through the fingertip. Even clear nail polish or a single layer of acrylic nails can obstruct the light beams, making it harder for the device to get a precise reading.
Additionally, there is a risk of bacterial or fungal growth underneath artificial nails, which can introduce extra bacteria or fungi into the operating room. Long nails, often associated with nail polish, may also hold more bacteria and germs, increasing the risk of infection. Hospitals maintain strict hygiene standards, and removing nail polish and artificial nails helps ensure a sterile surgical environment.
While some hospitals provide nail polish remover wipes, it is generally recommended to remove nail enhancements before arriving at the hospital. In some cases, hospital staff may remove the polish or acrylics, or they may use alternative monitoring sites. However, it is always best to check with your surgeon beforehand, as policies may vary between hospitals and procedures.
To ensure a safe and successful surgical experience, it is crucial to follow pre-surgery procedures and maintain clean, natural nails. While it may be inconvenient to forego a manicure before surgery, it is a small compromise compared to the potential risks of complications or rescheduled procedures.

Artificial nails can interfere with pulse oximeters
Several studies have been conducted to determine the effect of artificial nails on pulse oximetry readings. One study found that the application of unpolished acrylic nails resulted in a slight increase in pulse oximetry readings, from a baseline of 97.33% to 97.58%. However, the difference was not statistically significant, suggesting that unpolished acrylic nails may not significantly affect pulse oximetry measurements.
Another study examined the impact of different nail polish colours on pulse oximetry readings in critically ill patients. It was found that black, purple, and dark blue polishes caused the most significant interference, resulting in underestimations of oxygen saturation by up to 3-5%. Other colours, such as light-coloured polishes, had a lesser effect on the readings.
The impact of artificial nails on pulse oximetry readings may also depend on the type of pulse oximeter used. In some cases, the use of artificial nails may cause a clinically insignificant inaccuracy due to a compromised signal-to-noise ratio.
To ensure accurate readings and patient safety, hospitals often recommend removing artificial nails and nail polish before surgery. In some cases, hospitals may remove one nail or reposition the sensor to obtain a clear reading. However, it is always best to check with your surgeon or healthcare provider for specific instructions and guidelines regarding nail enhancements before undergoing surgery.

Nail polish can prevent accurate oxygen level readings
While preparing for surgery, patients often wonder about the guidelines surrounding nail enhancements and manicures. Hospitals and offices typically advise patients to remove nail polish before surgery, but why?
Nail polish can sometimes interfere with the accuracy of pulse oximeters, which are devices that clip onto a patient's finger to measure oxygen levels in the blood. This measurement helps ensure that the patient is getting enough oxygen during the operation. The sensor in the pulse oximeter uses light beams passing through the fingertip to gauge blood oxygen levels. If these light beams are blocked or distorted by dark, opaque polish, it can be challenging for the device to provide an accurate reading. Even a layer of clear nail polish can sometimes interfere with the device.
However, recent studies have suggested that nail treatments such as nail polish do not significantly affect readings from digital pulse oximetry (DPO) devices. This finding contradicts previous concerns that nail polish could impact the accuracy of oxygen level measurements during surgery. The study by Dr James Purcell and colleagues at University College Cork, and South Infirmary Victoria University Hospital, Cork, Ireland, surveyed healthcare professionals and experimentally assessed the effect of nail treatments on SpO2 measurements under different physiological conditions. They found that none of the nail treatments examined caused more than a 1% variation in SpO2 readings, which is within the manufacturer's specified range of ±2%.
Despite the findings of this recent study, it is still generally recommended to remove nail polish before surgery, especially dark-coloured polishes, to ensure accurate oxygen level readings and patient safety. This recommendation is supported by previous studies, which found that black, blue, and green nail polish significantly lowered oximeter readings of oxygen saturation. Therefore, to ensure the best outcome for patients, it is advisable to remove nail polish before undergoing surgery.

Nails can introduce bacteria and increase infection risk
Artificial nails, nail polish, and natural nails with certain characteristics can introduce bacteria and increase the risk of infection during surgery. This is because artificial nails and nail polish can interfere with the effectiveness of monitoring devices, such as the pulse oximeter, which is used to monitor a patient's oxygen levels during surgery.
The pulse oximeter is a small device that clips onto a finger to measure oxygen levels in the blood. It uses light beams that pass through the fingertip to gauge blood oxygen levels. If these light beams are blocked or distorted by thick acrylic nails or dark, opaque nail polish, it can be challenging for the device to provide an accurate reading. As a result, hospitals often recommend removing artificial nails and nail polish before surgery to ensure accurate monitoring and patient safety.
Nails, whether artificial or natural, can also introduce bacteria and increase the risk of infection during surgery. Paronychia, a common nail infection, can occur when bacteria enter broken skin near the cuticle and nail fold. Nail biting, picking at cuticles, and frequent manicures or pedicures can create tiny cracks or cuts in the nails or skin, providing an entry point for bacteria. Additionally, certain types of artificial nails and nail polish may be more prone to bacterial growth, further increasing the risk of infection.
To mitigate these risks, hospitals maintain strict hygiene standards and recommend removing artificial nails and nail polish before surgery. In some cases, hospitals may request that patients keep their nails short and natural to facilitate accurate monitoring and reduce the risk of introducing bacteria into the operating room environment.
It is important to note that the impact of nail polish on bacterial burden is still a subject of ongoing research. While some studies suggest that freshly polished nails do not have higher bacterial counts than unpolished nails, other studies indicate that standard nail polish may impede efforts to maintain low bacterial counts on the nails.

Hospitals may remove nail polish if patients forget
The pulse oximeter is a vital monitoring device used during surgery to measure the oxygen levels in a patient's blood. It is attached to the patient's finger or earlobe and uses light beams passing through the fingertip to gauge blood oxygen levels. Nail polish, especially opaque or dark-coloured polish, can interfere with the accuracy of this reading. Therefore, it is advisable to remove all nail polish and artificial nails before surgery to ensure patient safety and the smooth running of the procedure.
In some cases, hospitals may allow patients to keep their nail polish on if it is light-coloured or on toes, as it may not interfere with the pulse oximeter reading. However, it is always best to check with the surgical team beforehand to avoid any complications. Removing nail polish before surgery also helps maintain a sterile surgical environment, as chipped or peeled nail polish can contaminate surfaces and increase the risk of infection.
While hospitals may provide nail polish remover wipes or pads, it is essential to inform the surgical team if you have forgotten to remove your nail polish. They can then advise you on the best course of action and ensure that your surgery can proceed as scheduled. Overall, while nail polish may seem like a minor detail, addressing it properly is crucial for a successful and safe surgical experience.
