monopolar electrocautery
Electrosurgical technique using a single active electrode to cut or coagulate tissue during laparoscopic procedures.
Full Definition
Monopolar electrocautery is an electrosurgical method commonly used in minimally invasive surgery where electrical current flows from a single active electrode through the patient's body to a dispersive pad. This technique allows surgeons to cut tissue and achieve hemostasis during laparoscopic procedures. Unlike bipolar electrocautery, monopolar systems carry higher risk for thermal injury to surrounding tissues and require careful attention to electrode positioning and current settings.
Usage
Usage note: Always distinguish from bipolar electrocautery in surgical documentation.
In Context
- "The surgeon switched from monopolar electrocautery to clips for hemostasis near the ureter." — Operative report
- "Patient positioning must ensure proper contact with the dispersive pad when using monopolar electrocautery." — Safety protocol
