The effects of the combination of ketamine and medetomidine intravenous (IV) anaesthesia on haematological parameters were evaluated in six sahel goats comprising of 5 females and 1 male with mean body weight of 19 ± 1.4kg. Each goat was given a recommended dose of the drugs combination: medetomidine at 0.01mg/kg and ketamine at 5mg/kg body weight IV. Pre injection blood samples were obtained and at 15 minutes interval during anaesthesia in EDTA bottles and later analyzed. The parameters evaluated were packed cell volume (PCV), haemoglobin concentration (Hb), red blood cells (RBC), white blood cells (WBC), and differential leucocytes (neutrophils, eosinophils, basophils, lymphocytes and monocytes). The ketamine-medetomidine combination produced a significant decrease in PCV values from 30 minutes (24.00±1.23%) to 90 minutes (25.00±2.55%) compared with baseline value (29.50±1.52%); Hb also decreased significantly at 45mins. RBC and WBC values showed no significant difference compared with baseline values. Neutrophils decreased significantly at 45mins (35.17±3.25) compared to baseline value (41.50±3.67). There were no significant differences in lymphocytes, monocytes, and eosinophils values from baseline. The ketamine and medetomidine combination produced decreases in PCV, Hb and neutrophils. The goats recovered from anaesthesia uneventfully.
The effects of combination of medetomidine and thiopentone intravenous (IV) anaesthesia on haematological and some serum biochemical parameters in donkeys was investigated. A total of 5 donkeys, comprising of 3 females and 2 males with mean body weight (159 ± 16.63 kg) and age (3.45 ± 0.50 years) were used for the present study. Each donkey was given a recommended dose of medetomidine at 5µg /kg and 10 % thiopentone at 7mg/kg body weight IV. Preanaesthetic blood samples were collected and later at 15minutes interval during anaesthesia in EDTA bottles for haematological and biochemical analysis. The parameters evaluated were packed cell volume (PCV), haemoglobin concentration (Hb), red blood cells (RBC), white blood cells (WBC), and differential leucocytes (neutrophils, eosinophils, basophils, lymphocytes and monocytes) as well as serum biochemical parameters of alanine amino transferase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN) and Creatinine (Crea). The medetomidine-Thiopentone combination produced no significant difference (P>0.05) in all the haematological and serum biochemical parameters measured.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
