    CLINICAL EVALUATION OF END THREADED INTRAMEDULLARY PINNING FOR MANAGEMENT OF LONG BONE FRACTURES IN CANINES
    (CSKHPKV, Palampur, 2014-07-17) Chanana, Mitin; Adarsh Kumar
    The present investigation was undertaken to evaluate the clinical efficacy of end-threaded intramedullary pinning for management of various long bone fractures in canines. The study was carried out in two phases, managing 25 client owned dogs presented with different fractures. Initially, the technique of application of end threaded intramedullary pinning in long bone fractures was standardized in 6 clinical patients presented with long bone fractures. In this phase, end threaded pins of different profiles i.e. positive and negative, were used as the internal fixation technique. These patients, allocated randomly in two groups, when evaluated postoperatively revealed slight pin migration in group-I (negative profile), which resulted in disruption of callus site causing delayed union in one case and large callus formation in other two cases whereas no pin migration was observed in group-II (positive profile). Other observations in group-I was reduced muscle girth and delayed healing time as compared to group-II. In clinical application phase, on the basis of results obtained from standardization phase, 19 client-owned dogs clinically presented with different fracture, implanted with end threaded intramedullary positive profile screw ended self tapping pin. Immediate post-operative radiograph revealed anatomical reduction, good cortical contact and stable implant fixation whereas muscle girth showed an initial decrease followed by a gradual increase over time. The 21st and 42nd day post-op radiographical follow-up revealed no pin migration in any of the cases and there was no bone shortening or fragment collapse. Based upon the above observations, it was concluded that the end threaded intramedullary positive profile screw ended self-tapping pin used for fixation of long bone fractures in canines can resist pin migration, pin breakage and all loads acting on the bone i.e. compression, tension, bending, rotation and shearing to an extent with no post-operative complications. The implant was found economical and can be easily used in field conditions in managing long bone fractures in canines, as compared to other orthopaedic implants.

    DIAGNOSTIC ULTRASONOGRAPHY OF AN EQUINE ABDOMEN
    (CSKHPKV, Palampur, 2014-07-19) Farooq, Uiase-Bin; Adarsh Kumar
    The present work on equine abdominal ultrasonography was conducted in two phases. In standardization phase, detailed abdominal ultrasonographic scan was performed on native 10 adult (5horses and 5 mules) healthy equines of either sex to develop baseline topographical data of various organs. In this phase, the organs of right and left hemi-abdomen were topographically located, their echo-architecture was described. A baseline data of landmarks for locating different abdominal organs was elucidated. The sonographic calliper measurements of different organs were generated along with dynamic parameters of alimentary tract to help delineate the pathology. In clinical application phase, 14 clinical cases of equines suspected for abdominal disorders were subjected to ultrasonography for assisting the diagnosis. Colonic impactions were imaged as hyperechoic intraluminal structure casting a strong acoustic shadow. Bull’s eye or sandwich like appearance of intestinal loops was characteristic of intussusceptions and can be imaged transabdominally. Descending colon obstructions were imaged as a large hyperechoic intraluminal masses casting a strong acoustic shadow with loss of normal sacculations and peristaltic movement of descending colon. In case of peritonitis the peritoneum could be imaged as thin echogenic layer with lot of peritoneal fluid present inside the abdominal cavity with marked thickening of jejunal wall. It was concluded that thorough clinical investigation combined with ultrasonography was found to be an important diagnostic imaging aid for diagnosing different abdominal disorders in equines and equips the surgeon/clinician to identify the exact etiology, which helps reach at an accurate diagnosis and formulate a precise and efficient therapeutic plan.

    Evaluation of combination therapies for gastric ulcerations and erosions in dogs
    (CSKHPKV, Palampur, 2014-04-07) Suresh, Shastri Piyush; Tyagi, S. P.
    The study was conducted in 2 phases on 24 adult healthy medium sized mongrel dogs divided into 6 equal groups. In phase 1, Inj. Dexamethasone @ 1mg/kg, IV, b.i.d. was administered in all the animals until a predetermined severity of GUE was achieved and thereafter phase 2 commenced in which animals were subjected to no treatment, lansoprazole @1.5mg/kg, Seabuckthorn seed oil @1ml/dog, 40% Aloe vera pulp @ 5ml/dog, Lansoprazole @1.5mg/kg + 1ml Seabuckthorn seed oil and 4ml of 40% Aloe vera pulp + 1ml seabuckthorn seed oil p.o. b.i.d. till complete healing of GUE lesions. The progression of GUE was evaluated by gastro-endoscopic, clinical, fecal occult blood test, hematological and biochemical examinations at regular intervals. Gastro-endoscopic examinations revealed that by 10th day, 58.38% dogs reached the desired GUE index. Clinical examinations revealed a slight fluctuation in rectal temperature, heart rate and respiration rate but well within the normal limits. It accompanied 12.53% loss in body weight. Subjective assessment revealed a general lack of activity, reduced appetite (n=16/24) and occasional vomiting (n=5/24). The severity of gastric lesions evidenced endoscopically co-related well with melena observed in the dogs from 7th to 16th day with maximum severity on the 10th day (16/19) and there onwards. There was direct correlation between presence of gastric bleeding and positive fecal occult blood test. Haematological studies revealed a marked decrease in Hb, PCV, TEC, monocytes and lymphocytes. TLC and granulocytes exhibited significant increase on all observation intervals. Gastro-endoscopically, complete healing of GUE lesions during phase 2 was earliest in group 5 (combination of lansoprazole with seabuckthorn oil) at 7.5 days followed by group 2 (lansoprazole) at 9.0 days, group 1 (negative control) at 9.75 days, groups 3 and 6 (SBT oil and combination of SBT oil + Aloe vera) at 10.5 days, and the longest in group 6 (Aloe vera) at 14.25 days respectively. The severity of melena gradually decreased towards the end of study in all the groups with the animals of groups 5 and 3 showing earliest signs of improvement. Fecal occult blood test was positive in all the animals till there was endoscopic evidence of gastric bleeding. This test was found sensitive in diagnosing subclinical gastric bleeding. Clinical and haematological parameters improved markedly towards the end of phase 2. AST, ALT, BUN, creatinine and total protein remained within normal physiological limits throughout the study. It is concluded that the combination of Lansoprazole with SBT seed oil has synergistic therapeutic efficacy in dexamethasone-induced GUE in dogs, as it results in faster healing when compared with either of them used alone.

    Clinical evaluation of ketamine, propofol or ketamine-propofol admixture (Ketofol) for induction of anaesthesia in diazepambutorphanol premedicated and isoflurane maintained dogs.
    (CSKHPKV, Palampur, 2014-07-02) Kapil, Neha; Sharma, S. K.
    The purpose of this study was to clinically evaluate ketamine, propofol or ketaminepropofol for induction of anaesthesia in diazepam-butorphanol premedicated and maintained dogs. Thirty clients owned dogs of either sex were randomly divided into three groups BDP (Butorphanol-Diazepam-Propofol), BDK (Butorphanol-Diazepam-Ketamine) and BDKP (Butorphanol-Diazepam-Ketofol). All dogs were premedicated with atropine sulphate @ 0.04 mg/kg b. wt subcutaneously followed fifteen minutes later with Butorphanol tartarate @ 0.2 mg/kg b. wt IV. 5 minutes later Diazepam @ 0.5 mg/kg b. wt IV was administered followed by Propofol, Ketamine or Ketofol “till effect” IV for induction of surgical anaesthesia as per group. After induction, the animals were immediately transferred to isoflurane in oxygen. Observations recorded in dogs included analgo-clinical observations, cardiovascular observations, haemodynamic observations, anaesthetic response and dose, pulmonary responses and haemato-biochemical observations at various time intervals. The induction dose of propofol, ketamine or ketofol in BDP, BDK and BDKP group was 4.5±0.07 mg/kg, 5.0±0.23 mg/kg and 3.0±0.00 mg/kg respectively. Hypothermia was observed in BDP and BDKP group. Increased heart rate and fall in diastolic arterial pressure and increase in mean arterial pressure were observed in BDKP and BDK groups respectively after induction of anaesthesia with no rhythmic disturbance. The CVP remained below normal range in BDK group. SPO2 and ETCO2 remained in physiological limits in all the anaesthetic combinations. Significant respiratory depression occurred in BDKP group after induction. Transient apnea was observed in three animals in BDP group which was resolved after shifting of animal to 100% oxygen. Smoother induction and transfer were achieved by all the combinations. Recoveries were smoother, and excitement free in BDP group. Significant fall in Hb, PCV and TEC occurred in all the groups in early phase. Biochemical parameters remained within normal limits in all the groups. All the combinations used in present study and recommended for different types of surgeries in dogs.
