How to Remove a Leech

 

Basic methods:

(1) topical

(2) injection directly into the leech

(3) physical

(4) electrical

 

Topical treatments have included:

(1) dilute chloroform

(2) turpentine oil

(3) 5% cocaine

(4) hypertonic saline

(5) topical anesthetic

 

Injection (requires a leech of sufficient size to avoid accidental injection into the patient):

(1) 4% lidcocaine

 

Physical:

(1) grasping with forceps (works better on a mucosal surface compared to skin)

 

Electrical:

(1) bipolar electric shock (being careful not to shock the patient)

 

A combination of methods can be used such as topical anesthesia followed by forceps removal.
