[Liver hemostasis using a dry electrocautery or greased with lidocaine or neomycin or glycerin or vaseline, in rabbit].

Objective: To assess the hemostasis and healing of the hepatic parenchyma after segmental hepatectomy, using a dry electrocautery or an electrocautery greased with lidocaine gel, neomycin pomade, glycerin lotion, or a vaseline pomade.

Methods: Rabbits were submitted to partial hepatectomy and divided into six groups of 10 animals each: Group 1: untreated; Group 2: treated with a dry electrocautery; Group 3: treated with an electrocautery greased with lidocaine gel; Group 4: with neomycin pomade; Group 5: with glycerine lotion; Group 6: with vaseline pomade. Resected liver weight, bleeding volume and time spent to achieve hemostasis were determined.
