ABSTRACT
Background:Congenital defects, abnormalities of structures or functions present at birth, maybe as a result ofgenetic or environmental factors or both and in most cases; the exact etiology is not clear but can occur in all animals. These abnormalities are responsible for slowing down of genetic progress and economic loss for the breeders, due to the death of animals.Methods:Available record of cases presented to Aliyu JedoVeterinary Clinic,Sokoto from December 2015 to 2019 was used to investigate congenital malformation in ruminants based on species and sex. Surgery was carried out in all the cases with local anaesthesia (infiltration technique) using lignocaine. Surgical procedures carriedout were rectopexy (atresia ani), gingivectomy (gingival fibromatosis), superficial keratectomy and temporary tarssorhaphy (dermoid cyst), casting and physiotherapy (contracted tendons). Results:A total of 47 congenital malformations; atresia ani 22 (46.8%), gingival fibromatosis 18(38.3%), dermoid cyst 6(12.8%), and contracted tendon 1(2.1%) were reviewed in the study.The ovine species had the highest incidence of cases load recorded 23(48.93%) followed by bovine 17(36.17%) and then caprine species7(14.89%). The incidence of all malformations was higher in males (68.1%) than in females (31.9%). All cases were attempted surgically with success in all the procedures.Conclusions:It can be concluded that male ruminants have the highest prevalence of congenital malformation. Congenital malformations are more frequently seen in ovine and least seen in caprine. Atresia ani appeared to be the most commonly reported cases
ABSTRACT
Background:Epidural anaesthesia is one of the most frequently used regional anesthetic techniques recommended for surgical procedures caudal to the umbilicus in dogs. However, the use of lignocaine alone for epidural regional analgesia has been discovered to have shorter duration of analgesia and prolong onset of action, hence there is need to explore combinations of agents that will overcome this challenge. This study aimed to evaluate the anaesthetic/analgesic effect of cranial epidural anaesthesia in dogs undergoing cystotomy using Lignocaine in combination with acepromazine at the dose rates of 7 mg/kg and 0.05 mg/kg respectively.Methods:Eight apparently healthy matured, male and female dogs were used for the experiment. The onset and duration of analgesia was determined. The pulse rates, respiratory rates, mean arterial blood pressure, rectal temperature, complete blood count and the oxygen saturation level were determined at baseline, intra operative and post-operative.Results:There were no significant differences in all the parameters measured before and after the epidural administration of the agents. The onset of anaesthesia was rapid and the duration of anaesthesia was sufficient enough for the procedure to be carried out. However, there was significant difference in PCV, Hb and total RBC count between the baseline and other timing intervals. There were no significant differences in leucocytic and cardiopulmonary parameters between the baseline and other timing intervals.Conclusions:The epidural administration of lignocaine and acepromazine combination at the doses indicated can produced sufficientepidural anaesthesia with rapid onset for the purpose of cystotomy in dogs without major systemic influence on hemodynamic and cardiopulmonary changes
