Electrosurgical units (ESUs) have become essential components of current surgical operations, allowing for precise cutting, coagulation, and ablation of tissues while minimizing blood loss. As technology advances, ESUs provide surgeons with a safer, more regulated setting for various procedures. However, knowing their mechanisms and proper use is critical for avoiding potential risks.
In this complete tutorial, we will look at how electrosurgical machines work, the many modes of operation, safety regulations, and best practices for their use. This handbook is intended to educate healthcare workers so that the highest standards of patient care and surgical results are maintained.
What Are Electrosurgical Units?
An Electrosurgical Unit (ESU) is a medical equipment that employs high-frequency electrical currents to cut, coagulate, desiccate, or fulgurate tissue while performing surgery. It generates heat with electrical energy, allowing surgeons to perform precise cuts or stop bleeding without using mechanical effort. ESUs are versatile tools that increase surgical efficiency, making them important in operating rooms around the world.
Diamond Surgical prioritizes surgical precision, tissue control, and surgeon safety—all of which are achieved through our cutting-edge ESU technology. Our units allow surgeons to execute procedures with more control while minimizing hazards to both patients and practitioners..
How Electrosurgical Units Work
ESUs generate high-frequency electrical currents, which typically range from 200 kHz to 3.3 MHz. These currents are given to the tissue through an active electrode, causing a heating action that vaporizes or coagulates it. An electrosurgical unit performs two basic functions:
- Cutting (Electrotomy): When an ESU is set to “cut” mode, the high-frequency current vaporizes cells at the contact point, allowing the surgeon to slice through tissue precisely.
- Coagulation: The “coagulate” setting on an ESU operates by sending intermittent electrical pulses that generate heat, causing the blood to clot and reducing bleeding.
These modalities can be utilized independently or together, depending on the nature of the surgical process. Diamond Surgical’s innovative electrosurgical devices offer dual functionality and customizable choices to address a wide range of clinical needs.
Types of Electrosurgical Modes
ESUs can work in a variety of modes, each adapted to the needs of the surgery.
- Monopolar Mode: In the most frequent setting, monopolar electrosurgery involves transmitting an electrical current from an active electrode (handpiece) into the patient’s body, and a return electrode (grounding pad) is put on the patient to safely reverse the current. This type is very useful for cutting or coagulating big areas.
- Bipolar Mode: In bipolar electrosurgery, the active and return electrodes are integrated into the same surgical instrument, eliminating the requirement for a grounding pad. This procedure is commonly employed in more precise surgeries, such as neurosurgery or ocular surgery, where the tissue region is limited.
Both techniques serve particular purposes, and knowing when to use one over the other is critical to ensure surgical efficacy and safety.
Safety Concerns in Electrosurgery
While ESUs are integral in modern surgeries, they also come with certain risks. Understanding these risks and implementing safety protocols can prevent adverse outcomes, such as burns, tissue damage, or electrical shocks.
Here are some common safety hazards and how to mitigate them:
1. Burns from the Return Electrode
The return electrode or grounding pad is a critical component in monopolar electrosurgery. Improper placement or malfunction of the return electrode can result in burns, particularly if the electrical current isn’t properly dispersed.
- Safety Tip: Always ensure that the grounding pad is placed on a large, flat, and well-vascularized area of the body, free from hair, scars, or any obstructions. Proper inspection of the return electrode is essential before and during surgery.
2. Fire Hazards
Since electrosurgery generates heat, it can ignite flammable materials present in the operating room, such as oxygen, alcohol-based skin preps, and surgical drapes.
- Safety Tip: Ensure that the area is clear of flammable substances and vapors before using an ESU. Additionally, avoiding the use of high oxygen concentrations near the surgical field can reduce the risk of combustion.
3. Tissue Damage
Excessive heat from the electrosurgical unit can cause unintended tissue damage. The depth and precision of the cut can sometimes be difficult to control if the surgeon is not accustomed to the device.
- Safety Tip: Use the lowest effective power setting for the procedure, and ensure the active electrode is in good condition. Regular calibration of the ESU can also enhance precision.
4. Electric Shock
Though rare, improper handling of the electrosurgical unit can result in an electric shock to the patient or healthcare staff.
- Safety Tip: Always follow the manufacturer’s instructions when operating the ESU and inspect the cables, electrodes, and connections for any signs of wear or damage before use. It’s also advisable to use isolated power systems in the operating room to further prevent electrical accidents.
Best Practices for Using Electrosurgical Units Safely
Here are several best practices for ensuring the safe use of ESUs:
1. Staff Training
All medical staff involved in surgical procedures should be thoroughly trained in the safe use of electrosurgical units. This training should cover:
- Proper operation of both monopolar and bipolar modes.
- Placement of return electrodes.
- Recognition of potential hazards, such as burns, tissue damage, and fire risks.
At Diamond Surgical, we provide comprehensive training resources and support to ensure that medical professionals are proficient in using our ESUs.
2. Equipment Maintenance
Regular maintenance and inspection of electrosurgical units are essential for ensuring both functionality and safety. Some key maintenance tasks include:
- Checking the integrity of electrical cables and electrodes.
- Calibrating the unit to ensure accurate energy output.
- Ensuring that the return electrode monitoring system is working correctly.
A well-maintained ESU reduces the risk of malfunction, electrical shocks, and burns.
3. Patient Positioning and Grounding Pad Placement
As mentioned earlier, correct placement of the grounding pad is crucial in preventing burns. Ensure that the pad is placed away from bony prominences and metal implants, and on a clean, dry, and appropriately-sized surface of the patient’s skin.
4. Smoke Management
Electrosurgery often generates surgical smoke, which can be harmful to both the patient and surgical staff if inhaled. The smoke contains toxic chemicals and potentially infectious particles.
- Safety Tip: Always use a surgical smoke evacuation system in the operating room to minimize exposure to harmful fumes. A well-ventilated operating room is also advisable.
5. Power Settings
Using the lowest effective power setting for each procedure minimizes tissue damage and reduces the risk of burns. Surgeons should be familiar with the power settings and adjust them based on the thickness and type of tissue being operated on.
6. Communication
Clear communication among the surgical team is vital. Ensure that everyone involved understands the mode in use, power settings, and safety protocols. This teamwork can help prevent accidental injuries and promote a safe surgical environment.
