Robotic Surgery and Anesthesia – Dr. Subrata Chakravarty
What is Robotic Surgery?
Robotic surgery, also called robot-assisted surgery, uses a robotic arm to perform surgeries with greater precision, flexibility, and control than traditional techniques. This type of surgery often involves small incisions, known as minimally invasive surgery, but can also be used in open procedures.
How Robot-Assisted Surgery Works
- Minimally Invasive: Robotic surgery usually requires small cuts in the skin and surrounding tissue.
- System Components: The robotic system has three main parts:
- Surgical Cart: Equipped with four arms, the cart allows the surgeon to control the robotic arms in real-time.
- 3D Vision Tower: Provides a detailed, three-dimensional view of the surgical area.
- Control Console: The surgeon sits at the console to control the robotic arms, including two arms for handling instruments, one for holding the endoscope, and an optional fourth arm for extra tasks like countertraction and suturing.
- Enhanced Visibility and Control: Robotic systems improve the view of the surgical area, enabling surgeons to perform complex and delicate operations that might be challenging with traditional methods.
Types of Robotic Surgeries
Robotic surgery has become increasingly popular across various specialties, including:
- Prostatectomy
- Nephrectomy
- Cystectomy
- Gynecological surgery
- Abdominal surgery
- Cardiac surgery
- Thoracic surgery
- Pediatric surgery
Benefits of Robotic Surgery
- 3D View: Provides a unique, three-dimensional view of the surgical site.
- Reduced Infection Risk: Minimizes the chance of infections at the incision site.
- Less Pain and Blood Loss: Patients often experience reduced pain and bleeding.
- Quicker Recovery: Shortens the recovery period.
- Smaller Scars: Results in less noticeable scars.
Anesthesia in Robotic Surgery
Challenges for Anesthesiologists
- Limited Access: Large robotic equipment limits space around the patient, making access difficult once the robot is in place.
- Pre-Positioning of Equipment: The anesthesiologist must set up all lines, monitors, and protective devices beforehand and secure them to prevent displacement.
- Restricted Patient Access: Adjusting the patient’s position or accessing them is not possible without disconnecting the robot, which can delay treatment if an issue arises.
- Emergency Preparedness: The surgical team needs to be prepared to quickly detach the robotic system if an emergency occurs, as delays could lead to severe complications, especially in patients with pre-existing conditions or children.
- Movement Risks: Patient movement during surgery is strictly prohibited. Any shift could cause serious injuries like tearing or puncturing organs and blood vessels, potentially leading to life-threatening complications.
Positioning Considerations
- Extreme Positioning: Robotic surgeries require more extreme and steeper positioning of the patient compared to traditional surgeries, depending on the surgical area and type of procedure.
In summary, robotic surgery offers precision and quick recovery, but also presents specific challenges for anesthesia management due to limited access and the need for careful preparation and monitoring.
Challenges and Considerations for Robotic Surgery
With the rising demand for minimally invasive surgeries, robotic-assisted methods are increasingly preferred over traditional laparoscopic techniques. However, robotic surgery brings specific anesthetic and logistical challenges. Anesthesiologists need to address new factors related to patient positioning, equipment setup, and teamwork to ensure patient safety and successful outcomes.
Key Challenges in Implementing Robotic Surgery
High Cost
- Setup Costs: Robotic systems are expensive, costing from hundreds of thousands to millions of dollars.
- Ongoing Expenses: Maintenance, instrument replacement, and staff training add further costs, especially challenging for smaller hospitals.
- Cost-Saving Options: Leasing equipment or forming partnerships with manufacturers can help reduce expenses.
- Cost-Benefit Analysis: Evaluating potential long-term savings from better patient outcomes can justify these high initial costs.
Maintenance and Operational Costs
- Routine Maintenance: Regular upkeep can cost between $100,000 and $200,000 annually.
- Disposable Instruments: Tools like scissors and forceps can cost $700 to $3,500 per procedure.
- Financial Impact: While faster recovery times can offset some expenses, the ongoing costs remain substantial.
Training Requirements
- Specialized Training: Robotic surgery requires specific, ongoing training for surgeons and operating staff.
- Available Programs: Programs such as SAGES, ACS online modules, and hands-on workshops help staff develop essential skills.
- Maintaining Skill Levels: Continuous training ensures effective integration between human expertise and robotic capabilities.
Regulatory and Reimbursement Issues
- Strict Regulations: Guidelines from bodies like the FDA require time and resources to ensure patient safety.
- Reimbursement Policies: Coverage for robotic procedures varies, with some insurers not fully covering the costs.
- Negotiations with Insurers: Hospitals may need to work with payers to secure sufficient reimbursement for robotic surgeries.
Anesthetic Management Considerations
Limited Access
- Space Limitations: Robotic equipment restricts the anesthesiologist’s access to the patient once the robot is docked.
- Preparation: All lines, monitors, and devices must be positioned securely before surgery begins.
- Emergency Situations: If an emergency arises, the team must quickly undock the robot to adjust the patient’s position.
Patient Positioning
- Extreme Positions: Robotic surgeries often require extreme positions like steep Trendelenburg, increasing the risk of patient sliding.
- Risk of Injuries: Prolonged positioning and pressure from robotic arms increase the risk of crush injuries, especially for high-risk patients.
Airway Access
- Challenges in Upper Body Surgeries: In surgeries involving the upper abdomen, chest, head, or neck, the anesthesiologist’s access to the airway is limited.
- Securing the Airway: Ensuring secure airway placement and planning for emergencies are critical.
CO₂ Insufflation
- Use of CO₂: CO₂ is often used for internal access (pneumoperitoneum or capnothorax).
- Potential Complications: Risks include subcutaneous emphysema, pneumothorax, or gas embolism.
- Vigilant Monitoring: Anesthesiologists must watch for these complications and be prepared to respond quickly.
Summary
Robotic surgery offers many benefits, but it also requires specific adjustments in anesthetic management, staff training, and financial planning. Careful preparation, effective teamwork, and readiness for potential complications are essential for safe and successful robotic-assisted surgeries.
