Recommended Patient Positioning for Sacrocolpopexy
For sacrocolpopexy, position the patient in lithotomy with steep Trendelenburg tilt, ensuring both legs are moved simultaneously to prevent pelvic injury, with adequate staffing (minimum one person per leg for non-obese patients) and attention to hemodynamic monitoring given the significant cardiovascular effects of steep positioning. 1
Positioning Protocol
Lithotomy Position Setup
The lithotomy position is the standard approach for sacrocolpopexy procedures 2. Key technical considerations include:
- Move both legs simultaneously to prevent damage to the patient's pelvis 1
- Staffing requirements: One person per leg for patients who are not excessively overweight; additional staff may be needed for larger patients 1
- Patient weight considerations: The number of staff required depends on patient size and should be planned preoperatively 1
Steep Trendelenburg Considerations
Sacrocolpopexy, particularly when performed robotically, requires steep Trendelenburg positioning. This creates significant physiological changes that require monitoring:
Cardiovascular Effects: Steep Trendelenburg during robotic sacrocolpopexy causes:
- Mean 20% decrease in heart rate within 5 minutes of positioning 3
- Significant changes in autonomic nervous system modulation 3
- Decreased sympathetic and parasympathetic activity that persists for 30 minutes 3
- A second drop in heart rate occurring approximately 2 hours into surgery, lasting until procedure completion 3
Critical Safety Measures
Pressure Area Protection:
- Position patient in a stable and secure manner with attention to pressure areas 1
- Patient should be comfortable on the operating table 1
- Access to the patient should be unobstructed 1
Positioning Sequence:
- If using height-adjustable surfaces, raise the table before positioning to keep all handlers upright during the move 1
- Ensure the bed is at suitable height for transferring staff with pull point between waist and nipple line 1
- Use lateral transfer devices for anesthetized patients 1
Common Pitfalls to Avoid
Asynchronous leg movement: Moving legs independently can cause pelvic injury—this is the most critical error to avoid 1
Inadequate hemodynamic monitoring: Given the documented 20% heart rate decrease and autonomic changes with steep Trendelenburg, continuous cardiovascular monitoring is essential 3
Insufficient staffing: Attempting to position patients without adequate personnel increases risk to both patient and staff 1
Poor table height adjustment: Operating at incorrect table height increases musculoskeletal injury risk for surgical team and compromises patient safety 1
Mechanical Table Utilization
Modern mechanical operating tables can achieve Trendelenburg positioning mechanically, which protects staff from musculoskeletal injury but requires proper training 1. Knowledge and training in operating table mechanics is essential as improper use puts patients at risk 1.
