The Absolute Necessity of Dry Hands in Surgery
In the controlled environment of an operating room, every detail is managed to minimize the risk of infection. The process of preparing a surgeon's hands and arms, known as the surgical scrub, is a multi-step procedure that culminates in a specific and vital action: complete drying. The decision to dry hands completely before gloving is not a matter of convenience but a pillar of aseptic technique.
The primary concern is the potential for contamination. Wet skin surfaces can harbor microorganisms, and any residual moisture can become a conduit for bacteria to migrate through a tiny, unnoticeable defect in a surgical glove. Water can also drip down the arm and onto the sterile field or, worse, into the surgical site itself, leading to a surgical site infection (SSI). These infections are a serious complication of surgery and can lead to longer hospital stays, additional procedures, and increased healthcare costs.
The Science Behind Surgical Hand Antisepsis
The hand antisepsis process is designed to reduce the number of transient and resident microorganisms on the skin. Transient flora are microorganisms on the surface of the skin that can be easily removed by routine washing, while resident flora are more deeply embedded and difficult to remove. The surgical scrub aims to reduce both types to the lowest possible level and inhibit their regrowth for the duration of the surgery.
There are two primary methods for surgical hand antisepsis: the traditional scrub using an antimicrobial soap and water, and the use of an alcohol-based hand rub (ABHR).
- Traditional Scrub: This method involves a timed or counted-brush-stroke scrubbing of the hands and forearms with a surgical brush and antimicrobial soap, followed by rinsing under running water. After rinsing, the hands are held up above the elbows to allow water to drain away from the hands.
- Alcohol-Based Rub: For this method, a measured amount of alcohol-based antiseptic is applied to dry hands and forearms and rubbed in until completely dry. The rapid drying is key to the effectiveness of this method. In warm climates, an assistant may also spray alcohol on the hands to speed the drying process.
The Sterile Drying Technique
After the surgical scrub, a surgeon uses a sterile, disposable towel to meticulously dry their hands and arms. The standard procedure involves picking up the sterile towel and drying one hand thoroughly, moving from fingertips to the elbow, and never returning to a previously dried area. A new towel is then used for the other arm. This one-way motion ensures that any potential microbes are moved away from the more critical areas of the hand and fingertips. The hands are held high, above the elbows, throughout the process to prevent recontamination from gravity and proximity to the non-sterile body.
The Closed Gloving Technique
For procedures requiring a sterile gown, the closed gloving technique is often used to ensure the hands never touch the outside of the sterile gloves. After the hands are thoroughly dried, the surgical gown is donned, but the hands are kept inside the gown's cuffs. The gloves are then manipulated over the hands using the fabric of the gown, pulling them into place without the bare skin ever making contact with the outer surface of the sterile glove.
Comparison: Wet vs. Dry Gloving Consequences
| Aspect | Gloving with Wet Hands | Gloving with Dry Hands |
|---|---|---|
| Risk of Contamination | High. Moisture can facilitate bacterial migration through micro-perforations in the glove, potentially contaminating the sterile surgical site. | Negligible, provided proper aseptic technique is followed. The lack of moisture eliminates a key vector for microbial transfer. |
| Glove Integrity | Compromised. The friction and tackiness of wet hands make it much more difficult to put on gloves, increasing the risk of tearing or stretching the material. | Maintained. Gloves slide on smoothly, reducing the chance of rips and ensuring the protective barrier remains intact. |
| Ease of Donning | Difficult and frustrating. The gloves can stick and roll up, complicating the process and increasing the risk of breaking sterility. | Smooth and efficient. The process is streamlined, allowing the surgical team to proceed quickly and maintain focus. |
| Infection Risk | Elevated. The risk of surgical site infections (SSIs) increases due to potential bacterial transfer. SSIs can lead to serious post-operative complications. | Minimal. The controlled environment and adherence to sterile procedures significantly reduce the risk of SSIs. |
| Glove Removal | Less critical for maintaining sterility, but proper technique is still required to prevent self-contamination. | Critical for maintaining sterility, especially for double gloving and proper disposal to prevent cross-contamination. |
The Role of Alcohol-Based Hand Rubs
Many healthcare facilities now utilize alcohol-based hand rubs for surgical antisepsis, as they have been shown to be effective and are often less irritating to skin with repeated use. When using ABHR, the process is slightly different but still emphasizes the importance of a completely dry application. The antiseptic solution is rubbed onto the hands and forearms, covering all surfaces, and then allowed to air-dry completely. The rapid evaporation of alcohol ensures the hands are dry and antiseptic before the gloves are donned.
Double Gloving and Indicator Systems
Because gloves can and do fail during surgery, many surgeons opt to double glove. Some double-gloving systems use an indicator glove underneath the outer glove. If the outer glove is compromised, the change in color of the inner glove becomes visible, alerting the surgeon to the breach in sterility. Even with this safeguard, the practice of donning gloves over dry hands remains non-negotiable.
The Importance of Aseptic Technique as a Whole
This is just one facet of the extensive training and protocol that surgeons and operating room staff undergo. From the initial hand scrub to the precise placement of sterile drapes, every action is designed to protect the patient from a preventable infection. The standard of completely drying hands is a small but indispensable part of a larger system of infection control.
Conclusion
In surgical settings, the strict adherence to protocols is paramount for patient safety. The question, "Do surgeons put gloves on wet hands?" is met with an emphatic no, as the practice is a fundamental rule of aseptic technique. Drying hands completely after the surgical scrub is essential to prevent microbial contamination, maintain glove integrity, and minimize the risk of serious surgical site infections. By understanding this critical step, we can better appreciate the intricate and diligent processes that protect patients during invasive procedures.

What if a surgeon's gloves get wet during surgery?
If a glove gets wet, or is suspected to have been compromised, it must be changed immediately. This is often why surgeons double glove, as they can remove the outer glove without compromising the sterility of the inner one. The same strict aseptic protocols are followed during the changing process to prevent any contamination.
