The Tsavo Mobile Veterinary Unit
Field Report - January 2013
Return to the David Sheldrick Wildlife Trust
The month of January saw several veterinary activities in the region mainly in Elephants and a lion. Most of the cases were handled by a team from Nairobi as the resident Vet was on leave. The area is fast drying up though most water holes still have plenty of water. Cases are expected to increase after most water holes dry up and conflicts assume an upward trend.

She had enormously swollen right hind leg; an arrow head was found deeply embedded in tissues and removed. The wound was 20cm in diameter and about 10cm in depth with various pus sinuses and lots of dead tissue. The wound was cleaned with copious amounts of water and dead tissues removed. The wound was cauterized and severally lavaged with hydrogen peroxide and later liberally cleaned with Lugols iodine. The wound was sprayed with Oxytetracycline spray.
