Scrub nurses
In the healthcare industry, a scrub nurse, also known as a perioperative nurse, surgical nurse, or operating room nurse, is a critical and vital part of the surgical team. Scrub nurses ensure that operations run smoothly, efficiently, and safely. They work behind the scenes in the operating room (OR) and play a pivotal role before, during, and after surgeries.
The role of a scrub nurse is diverse and encompasses a wide range of responsibilities. Before a surgery, they prepare the OR by ensuring that all necessary surgical instruments and supplies are sterile and readily available. They verify patient identification and the surgical site to prevent errors. Setting up the sterile field includes draping the patient and creating a sterile environment around the surgical site. During the surgery, scrub nurses assist the surgeon by handing them sterile instruments, sutures, and supplies. They anticipate the surgeon's needs, ensuring a seamless flow of instruments and equipment. They also monitor the patient's vital signs, ensuring they are stable during the surgery. After the surgery, scrub nurses assist in the postoperative care of the patient, helping to transfer them to the recovery area while ensuring their safety and comfort.
To become a scrub nurse, one typically needs a combination of education, training, and experience. Scrub nurses usually begin their careers by obtaining a nursing degree, either as a registered nurse (RN) or licensed practical nurse (LPN). Many scrub nurses also pursue certification in perioperative nursing, such as the Certified Perioperative Nurse (CNOR) credential. Continuing education is important in this field, as perioperative nursing is continually evolving, and scrub nurses need to stay current with best practices and advancements in surgical care.

Scrub colours
Scrubs are the sanitary clothing worn by physicians, nurses, dentists, and other healthcare workers involved in patient care. They are designed to promote a clean environment and are usually made of inexpensive, durable, and easy-to-clean fabric.
The colour of scrubs can vary and often holds specific meanings and purposes. Some hospitals assign certain scrub colours to specific types of staff or departments, while others leave the choice to the individual. Here are some common colours of scrubs and their meanings or purposes:
Green Scrubs
Green scrubs are commonly worn by surgical personnel, including surgeons, surgical technicians, and operating room staff. This is because green is opposite to red on the colour wheel, helping doctors avoid visual fatigue from looking at red-coloured organs and the pink hues of blood during operations. Green scrubs also neutralise the colour of blood, making stains appear less vivid.
Blue Scrubs
Blue scrubs are commonly worn by nurses and are said to promote tranquility and feelings of peace. Ciel blue, a light shade of blue, is recognised for its calming and soothing effects. Blue scrubs are also practical as the colour neutralises blood stains, making them a popular choice for surgical teams and healthcare professionals in stressful environments.
White Scrubs
White scrubs are traditionally worn by lab scientists and nurses, symbolising cleanliness and purity. Although they are not as common today due to being difficult to keep clean, they still offer a professional and clinical appearance, especially in women's health settings.
Black Scrubs
Black scrubs offer a sleek, professional, and authoritative look. They are often worn by senior staff or in specialised departments, conveying confidence and distinction. Black scrubs are also practical as they can conceal stains and dirt, making them suitable for high-stress environments like emergency departments.
Other Colours
Scrubs come in a wide variety of colours, and different colours may be chosen to match the specific department or role. For example, purple scrubs are associated with spirituality and wisdom and are often worn in settings like hospice care or psychiatric units. Maroon scrubs may be worn by anaesthetists, and paediatric nurses often wear more colourful options like pink or purple to add warmth and care to their interactions with patients.
Additionally, some hospitals may use custom-made printed scrub tops with cheerful prints, especially in paediatricians' offices, veterinary offices, dental clinics, and children's hospitals.

Scrub tech
A scrub tech, also known as a surgical technologist, is a vital member of the surgical team who assists surgeons in the operating room. They are responsible for ensuring a sterile and organized environment and play a critical role in infection prevention.
The duties of a scrub tech extend beyond simply handing instruments to the surgeon. They are involved in the entire surgical process, including the preoperative and postoperative stages. Before a surgical procedure, scrub techs help prepare the operating room by setting up instruments, ensuring their sterility, and laying out necessary equipment. They also assist in preparing the patient for surgery by cleaning and shaving the skin, transferring the patient to the operating table, and covering them with sterile drapes. During the surgery, scrub techs pass instruments, sponges, and dressings to the surgeon, while also maintaining sterility. They may also assist with tasks such as holding organs steady, applying suction, or helping with suturing.
After the surgery, scrub techs are responsible for safely gathering sharp and delicate instruments, ensuring that disposable instruments are discarded or sterilized for reuse, and restocking the supply room. They also play a crucial role in surgical counting, which involves taking inventory of all tools and instruments used during the procedure to ensure nothing is accidentally left inside the patient.
To become a scrub tech, individuals must complete a diploma, certificate, or associate's degree program in surgical technology. These programs offer comprehensive coursework and hands-on training in areas such as sterilization techniques, equipment handling, patient care, and anatomy. Formal education and certification are essential for this role, as scrub techs must possess extensive knowledge of surgical procedures and maintain high standards of sterility and patient safety.

Scrubbing in
In a hospital setting, "scrubbing in" refers to the process of preparing for a sterile surgical environment. This process is critical in minimising the risk of infection and enhancing patient outcomes. All members of the surgical team, including surgeons and surgical technologists, must "scrub in" before each operation.
The act of "scrubbing in" involves a thorough cleaning process, focusing on the hands and arms. Surgical personnel will scrub their hands and forearms, down to the elbows, using the WHO handwashing procedure. This step should last for a minimum of one minute. Next, the soap is washed off by running water from the tap, with arms held up so that the water runs off into the sink from the elbows. This procedure is repeated three more times: once down to the mid-forearm, then to the wrists, and finally, just the hands, with each step lasting a minimum of one minute.
After the scrubbing process, the hands and forearms are dried with sterile towels from the gowning pack. This is done using a dabbing motion instead of wiping, and a separate towel is used for each hand before disposal. Following this, the surgical team members don a sterile surgical gown and gloves, creating an aseptic environment.
The term "scrub" also refers to the sanitary clothing worn by medical professionals during surgery. These include gowns, gloves, masks, and caps. Originally designed for surgeons and operating room personnel, scrubs are now worn by various hospital personnel, including physicians, nurses, dentists, and other patient care providers. Scrubs are designed to be simple, with minimal places for contaminants to hide, easy to clean, and inexpensive to replace if damaged or irreparably stained. They are typically made from high-quality fabric that can withstand thorough cleaning and are designed for maximum use and cost efficiency.
