Tsavo Mobile Veterinary Unit - March 2013

Introduction The Month of March witnessed an increase in injury cases especially in Elephants with arrow injuries leading followed closely by snares

Introduction

The Month of March witnessed an increase in injury cases especially in Elephants with arrow injuries leading followed closely by snares. Many of the arrow wounds targeted bulls, a clear indication of poaching attempts due to their huge tusks. The hotspots were Ithumba, southern Tsavo East and Tsavo West near Mwakitau. Other cases included rescue of an abandoned crocodile at a closed down facility in Bachuma gate, treatment of a sick security dog and autopsy of lion carcass. Cases are expected to reduce owing to the oncoming rains that have already started.

Examination:

A big wound on the left rear leg was examined and on further probing an arrow head was retrieved from the wound. Dead tissues were debrided and the septic wound cleaned using water mixed with hydrogen peroxide at a ratio of 1:1. Tincture of iodine and oxytetracycline spray was applied to the wound and a final cover of green used to cover the injured site. Long acting Amoxycillin was injected parenterally.
