Mouse Spleenectomy

OUTLINE
PROTOCOL

General anesthesia
1. inject i.p. 250µl/mouse of the ANESTHETIC mixture < wait for 2-10min for the anesthetic effect>
2. for verify the anesthetic effect check plantar reflexes (animal must be unresponsive to squeezing hind feet)

1. wash the surgical and adjacent area with C 2H5OH-70% 
2. raze the fur with the razor
3. wash the surgical area withC2 H 5 OH-70% 

Operation

2. Gently trap and push the spleen free of adjacent tissue, separate its leg with blunt-ended scissors or forceps

3. By a single knot tie off the artery with a 3-0 plane CATGUT by looping the suture through the mesentary (the artery enters the spleen at the superior polus). If necessary by a single knot tie off the efferent venule (exits the spleen at the inferior polus)

4. Cut away the connective tissue and remove the spleen

5. Apply on the open wound 1 pinch of Astrexene (Chlorhexidin HCl) (5mg/g)

6. Apply on the peritoneum and muscles the U-like suture with plane CATGUT (3-0)

7. Apply on the skin the U-like suture with ETHICON MERSILENE (3-0)
