Prognosis is good, wounds respond well to treatment Treatment and conclusion Thorough wash with water, dilute hydrogen peroxide and debridement of necrotic tissue. Tincture of Iodine soaked in gauze swabs was the applied 1% Ivermectin 300mg administered subcutaneously 20% Oxytetracycline 20000mg administered intramuscularly The rhino unit was advised to monitor the animal and report after 10 days if repeat treatment is necessary. The affected black rhino will require helicopter darting because it inhabits a thick bush. Injured Grevys Zebra in Laisamis Species: Grevy Zebra Age: Adult Sex: Male Location: Naibei N 0149.603ʹ E03732.420ʹ Introduction The Meru Mobile Veterinary Unit was requested by scouts from the Grevy Zebra Trust (GZT) in Laisamis to attend to an injured grevy zebra. This animal showed lameness and swelling on its right forelimb. The zebra occurred among herds of grevy zebras in community land in Naibei, Laisamis which are monitored by the scouts from the GZT. Grevy zebra species are currently listed as endangered by the IUCN/ SSC Equid specialist group hence an urgent need to intervene whenever there are reports of injury or disease. Chemical immobilization We used Etorphine Hcl 7mg and Xylazine 80mg in a 3cc Dan-Inject dart with a 2.0 40 mm needle. Darting was conducted by vehicle after a brief chase. The dart was placed caudally on the left flank. Induction time (down time) was 8 minutes. On contact with the animal, opticlox ointment was applied on the dart wound and eyes to prevent desiccation of the cornea. Vital parameters such as respiration and tissue perfusion were continuously monitored to ensure that the narcotized animal was stable. After the procedure, Diprenophine 24 mg and Atipamezole 15mg were administered intravenously into the jugular vein to reverse the effects of etorphine and xylazine respectively. Physical examination Leg carrying lameness with a swelling on the right forelimb at the carpal joint and penetrating wounds laterally and medially. The wounds were suggestive of bites which may have been caused during territorial fights. Joint ligaments may have been torn. Diagnosis: Traumatic injuries on the right carpal joint.
Prognosis for recovery is good though the joint may take some time to heal. Treatment Thorough wash with plenty of water and topical application of Tincture of Iodine and Oxytetracycline spray Anti- inflammatory drug: 5% Flunixin Meglumine 1000mg administered intramuscularly Antibiotic: Amoxicillin trihydrate 3000mg administered intramuscularly Cheetah with fracture in Solio Ranch Species: Cheetah Sex: Male Age: 8 years Owner: Solio ranch Rangers in Solio ranch requested for treatment of a cheetah which showed lameness on its forelimb. The cheetah was reported to be in poor body condition because he was unable to hunt. The Meru MVU was called to immobilize the animal for examination and treatment. Chemical immobilization We used Ketamine Hcl 100mg and Medetomidine Hcl 1mg in a single 1.5 milliliter DanInject dart with a 1.5 30 mm needle. Darting was conducted by vehicle with the dart placed on the right thigh muscles. Induction time was approximately 10 minutes. On contact with the animal a blind fold put to prevent visual stimulation. Physical examination Leg carrying lameness on the left forelimb; body condition score was 2 on a scale of 1 - 5. On manipulation of the limb crepitus was felt at the humerus and palpation revealed bone fragments. Diagnosis: Comminuted fracture of the humerus. The cause of the fracture was unknown. Case management: euthanasia Blood and ear tissue samples were taken for genetic studies 20% Pentobarbital sodium 10ml injected intravenously through cephalic vein. Ranch management was advised to bury carcass Discussion Comminuted fractures are difficult to manage under field conditions because they require specialized invasive surgical techniques to fix the humerus. The decision to euthanize this cheetah was made in consultation with the ranch management considering the welfare of this animal, age and its quality of life after surgical intervention.
Injured Elephant in Marsabit national park Species: Elephant Sex: Male Age: 11 years Location: Bakuli, Marsabit NP Rangers on patrol reported an elephant showing lameness with poor body condition in Bakuli, Marsabit NP. The elephant which could hardly move because of pain on its hind limb had been on the same spot for about 5 days. Visual inspection of the animal showed no injury. Chemical immobilization and examination We used Etorphine Hcl 12mg in a 1.5 milliliter DanInject dart with a 2.2 60mm needle. Due to thick bush and bad terrain for vehicles in Marsabit NP darting was conducted on foot. The dart was placed on the left rump with the animal going down after 5 minutes. On contact with the animal its trunk was extended and nostrils were kept patent to prevent obstruction of the airways. A blindfold was used to prevent visual stimulation. The animal was in poor body indicating that it was a long standing case. It had a swelling on the distal part of the right hind limb at the tarsus extending to the hoof. No significant findings (no foreign body nor pus) after thoroughly washing of the hoof with soap and water and aspiration. Fracture of the tarsal bones was suspected which though rare may occur.
Treatment: i. 0.1% Dexamethasone sodium 50mg administered intramuscularly ii. Betamox trihydrate 30000mg intramuscularly iii. Multivitamin 200ml intramuscularly Prognosis: Guarded, this was a long standing case and the body condition had deteriorated significantly. The animal died after 5 days from the time it was treated. Eye examination of blind black rhinos in Ol Jogi ranch This activity was conducted in collaboration with the Lewa Veterinary Unit, Ol Jogi Ranch and veterinary ophthalmologists from Kenya and South Africa. Meru MVU assisted in immobilization and monitoring of anaesthesia in anaesthetized animals. Two black rhinos 10 month old and 3 year old were immobilized using etorphine. Temperature, rate and depth of respiration and tissue oxygen perfusion were monitored during the procedure. Ultrasound examination of the structures of the eye revealed extensive damage of the retina which could not be corrected by surgery in both cases. The cause of blindness was thought to have been congenital.
Both animals were successfully reversed from anesthesia. Post mortem examination of a black rhino in Aberdare national park A rhino carcass with its horns intact was found near a water hole in Aberdare national park and a request was put to the Meru MVU for a post mortem examination to determine the cause of death. The carcass had been extensively consumed by hyenas therefore the viscera, gluteal and rectal parts were missing. Methods used included flaying, incising and sectioning. Findings: Carcass on right lateral recumbency with puncture wound on the left thoracic area with comminuted fracture of the rib. The wound was suggestive of a gun shot injury. No projectile was retrieved.
Cause of death: Injuries associated with gun shot Report by:Bernard Rono
