Acrylic nails are artificial nail extensions that are often used for cosmetic purposes. While they may enhance the appearance of one's hands, there are several reasons why it is recommended to remove acrylic nails before undergoing surgery. Firstly, surgical environments require utmost cleanliness to minimize the risk of infection, and artificial nails can introduce bacteria or fungi into the operating room. Additionally, during surgery, medical professionals use a pulse oximeter, a device that measures oxygen levels in the blood by clipping onto a patient's finger. Acrylic nails, along with nail polish, can interfere with the accuracy of the pulse oximeter's readings, potentially impacting patient safety. Therefore, it is generally advisable to remove acrylic nails and nail polish before surgical procedures to ensure a sterile environment and accurate patient monitoring.

Pulse oximetry
While it is not unusual for patients to present for surgery wearing acrylic nails, they can sometimes interfere with the accuracy of pulse oximetry readings. Pulse oximetry is a simple, non-invasive method that is widely used to monitor the oxygen saturation in a patient's blood during surgery, anaesthesia, sedation, and transfer of critically ill patients. It involves placing a device on the finger that measures oxygen levels through the fingernails.
Acrylic nails, gel nails, or multiple layers of nail polish can interfere with the accuracy of pulse oximetry 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 acrylics or dark, opaque polish, the device may struggle to get an accurate reading.
However, the effect of nail polish and acrylic nails on the accuracy of pulse oximetry readings is inconsistent. While some studies have found that dark colours like black, brown, blue, and green reduce oxygen saturation readings, other studies have shown that nail polish colour does not have a clinically significant effect on pulse oximetry readings. One study found that unpolished acrylic nails did not affect pulse oximetry measurements, suggesting that patients may not need to remove them before surgery.
To ensure patient safety and the smooth running of the procedure, it is generally recommended to have at least one natural nail free from acrylic or gel, often on the index finger, so that the pulse oximeter can get a clear reading. It is advisable to remove artificial nails a day or two before the operation to avoid any delays or complications related to nail coverings on the day of surgery.

Patient safety
Ensuring patient safety is the utmost priority in a surgical environment. One of the critical aspects of patient safety during surgery is maintaining a sterile environment to minimise the risk of infection. Acrylic nails and gel polish can chip or peel, leading to the potential contamination of sterile surfaces. Additionally, long nails, which are common among those who use nail polish, may harbour bacteria and germs, increasing the risk of infection. Therefore, it is advisable to remove all artificial nails and gel polish before surgery.
Another important reason for removing acrylic nails before surgery is to ensure accurate vital sign monitoring. One of the simplest and most effective ways to monitor vital signs during surgery is by using a pulse oximeter, a small device that clips onto a finger to measure oxygen levels in the blood. Acrylic nails, gel nails, or thick layers of nail polish can interfere with the accuracy of this reading. The sensor uses light beams that pass through the fingertip to gauge blood oxygen levels, and if these light beams are blocked or distorted, the device may struggle to provide an accurate reading.
To ensure a safe and smooth surgical experience, it is recommended to remove acrylic nails and nail polish before surgery. This allows for accurate monitoring of vital signs and helps maintain a sterile environment, reducing the risk of infection. While it may be permissible to use specific types of nail polish, such as clear and chip-resistant varieties, it is crucial to consult with the surgeon beforehand to adhere to their specific requirements.
In summary, removing acrylic nails and nail polish before surgery is essential for patient safety. It helps maintain a sterile environment, reduces the risk of infection, and ensures accurate vital sign monitoring. By following the recommendations and guidelines provided by healthcare professionals, patients can actively contribute to a successful and complication-free surgical experience.

Risk of infection
Acrylic nails can increase the risk of infection during surgery. Hospitals maintain strict hygiene standards to reduce the risk of infections. Artificial nails can introduce extra bacteria or fungi into the operating theatre environment. Long nails, which are common among those who use nail polish, may also hold bacteria and germs, increasing the risk of infection.
Additionally, it is critical to monitor a patient's oxygen levels during surgery. This is typically done using a pulse oximeter, a small device that clips onto a patient's finger to measure oxygen levels in the blood. Acrylic nails can interfere with the accuracy of this device, as it uses light beams that pass through the fingertip to gauge blood oxygen levels. If these light beams are blocked or distorted by thick acrylics, the device may struggle to provide an accurate reading.
To ensure a patient's safety and the smooth running of the procedure, it is recommended to remove acrylic nails before surgery. This allows for accurate oxygen level monitoring and helps maintain a sterile environment, reducing the risk of infection.
In some cases, surgical facilities may permit the use of clear, liquid-fast-drying, and chip-resistant nail polish. However, it is essential to consult with your surgeon before the procedure and follow their specific recommendations.

Monitoring vital signs
While well-applied acrylic nails are generally safe, hospitals recommend removing them before surgery. This is because acrylic nails, gel nails, or multiple layers of nail polish can interfere with the accuracy of pulse oximetry, a simple and effective method to monitor a patient's vital signs during surgery.
Vital signs commonly monitored postoperatively include heart rate, blood pressure, respiratory rate, body temperature, and oxygen saturation. An increase in heart rate and respiratory rate could indicate the onset of sepsis or infection, while a drop in blood pressure may signify internal bleeding or hypovolemia. Monitoring oxygen saturation is also important, as low oxygen levels can cause cyanosis.
The frequency of vital sign monitoring depends on the patient and their condition. In a post-operative recovery unit, vitals are typically taken every 15 minutes for the first hour, every 30 minutes for the next 2 hours, and then every 4 hours for the next 24 hours. However, this schedule may be modified to allow for earlier detection of abnormal conditions.
Vital sign monitoring also helps assess the effectiveness of pain management. Pain medications can have side effects that affect vital signs, so monitoring helps determine the appropriate medication and dosage to avoid adverse effects. For example, opioids can cause respiratory depression, leading to a drop in respiratory rate or oxygen saturation.
In conclusion, monitoring vital signs is an essential component of post-operative care. It helps detect and treat complications early, assess pain management, and determine the patient's readiness for discharge.

Sterile surgical environment
Nail polish, including artificial nails and gel polish, can interfere with the accuracy of pulse oximeters, which are vital monitoring devices that measure oxygen levels in the blood. The pulse oximeter is typically attached to the finger or earlobe, and the nail bed is one of the best places to detect cyanosis, a bluish discolouration caused by low oxygen levels. If the sensor's ability to detect oxygen levels is impaired by nail coverings, it can affect the results and impact patient safety.
To ensure a successful and complication-free surgical experience, it is recommended to remove nail coverings before surgery. This allows for any issues, such as dry or irritated nail beds, to heal naturally before the procedure. It is generally advised to remove artificial nails and nail polish a day or two before hospital admission to avoid stress and discomfort and ensure a clean and sterile surgical environment.
In certain cases, some surgical facilities may permit the use of clear, liquid-fast drying, and chip-resistant nail polish. However, it is crucial to consult with the surgeon beforehand to confirm their specific requirements and guidelines. Overall, maintaining a sterile surgical environment takes precedence, and removing artificial nail products is an essential step in achieving this goal.
