Comparison of conventional methods with commercially available topical hemostat surgical snow (oxidized cellulose) for achieving hemostasis in canine model of partial splenectomy.

Abstract

Spleen is highly vascularized organ and bleeding control during partial splenectomy is a big challenge. In this study conventional methods of electrocautery, absorbable suturing and advance methods of topical hemostat Surgicel® were compared to control bleeding during partial splenec- tomy. Twelve healthy dogs (n=4) were divided in A, B and C groups. After partial splenectomy Surgicel®, electrocautery and absorbable horizontal mattress sutures were used to control hemor- rhages in group A, B and C respectively. Bleeding time and loss of blood volume was evaluated during surgery. In addition, blood samples were taken on day 0 pre-surgery and on days 3, 10 and 17 post-surgery to evaluate changes in biochemical parameters after the application of dif- ferent hemostatic techniques. Ultrasonography was also performed at alternative days to check any gross changes in the spleen. Dogs in group A showed minimum bleeding time and loss of blood volume as compared to group B and C. Drop in red blood cells count was compared be- tween group A, B and C showing significant change (p≤0.05) at day 3, 10 and 17, while a sig- nificant decline in hemoglobin was found in group C followed by groups B and A at 3rd and 10th day. There was no difference between platelet counts in various groups. Ultrasonography showed no significant changes in the spleen parenchyma. It was concluded that Surgicel® was an effective material for controlling hemorrhage in veterinary patients.
