Recommended Power Settings for Electrosurgical Units (ESU) in Different Surgeries
The appropriate power setting for an electrosurgical unit varies depending on the type of surgery. Below is a general guideline for power selection in different procedures:
1. Power Classification by Surgery Type
Low Power (<30W)
Dermatological procedures
Laparoscopic sterilization
Neurosurgery
Oral/dental surgery
Cosmetic microsurgery
Vasectomy
Medium Power
Cutting: 30–100W | Coagulation: 30–70W
General surgery
Head & neck (ENT) surgery
Laparotomy
Orthopedic surgery
Polyp resection
Thoracic surgery
Vascular surgery
High Power
Cutting: >100W | Coagulation: >70W
Tumor ablation
Mastectomy (Cut: 180–300W | Coag: 70–120W)
Thoracotomy (High-intensity coagulation: 70–120W)
Transurethral resection (TURP) (Cut: 100–120W, depends on loop size & technique)

Important Notes:
These settings are for reference only. Actual power may vary depending on:
ESU brand/model (e.g., Valleylab, ERBE, ConMed)
Surgeon's technique & preference
Tissue type & patient factors
Excessive power can cause thermal injury, while insufficient power may lead to poor hemostasis or ineffective cutting. Always follow manufacturer guidelines and adjust based on real-time surgical feedback.
