Publisher: 1994Dissertation note: The fracture of patella usually falls in a special type of fracture, which is not treated by ordinary limb and bone fixation devices. Hence emphasis is given to counteract the distracting forces and to convert them into compressive forces to achieve the desired effects. Different types of internal fixation devices have been tried in the past for the repair of avulsion fractures like Tension Band wire, compression screws, compression plates, an steel sutures.
This study was conducted on 20 mongrel dogs divided into two groups of 10 animals each. These groups were designated as group A and group B. Two methods, Tension Band wire and square steel suture were used for the repair of transverse patellar fracture in dogs.
In group A, the right patella was surgically exposed, fractured and repaired by Tension Band wire with Thomas Splint on the same limb when the operated dog started bearing weight on its operated leg, the left patella was exposed and repaired using same technique but without Thomas Splint.
In group B the right patella was repaired by square steel suture with Thomas Splint. After six weeks, the left patella was operated and repaired using same technique but without Thomas Splint. The dog of each group was kept for a period of 16 weeks after surgery. The results were obtained on the basis of their clinical and radiographic picture.
The results of this study indicate that the use of steel suture is a better fixation device for the repair of transverse patellar fracture.

Publisher: 1995Dissertation note: These days the scope of anaesthesia is consistently increasing due to increase in surgical patients in veterinary practice. This change in trend is due to the awareness of the owners to different surgical problems and their solutions. They do not hesitate to get their animals treated with modern equipments and highly expensive medicine. To meet this challenge and demand of the owners, veterinary surgeons are taking keen interest to get the advanced knowledge and latest information of modern equipments and their usage in veterinary practice.
In the past surgery was performed by making temporary insensibility by asphyxiation, cerebral concussion by striking wooden bowl placed over the head with a hammer and a regional anaesthesia was attained by compression of nerves and blood vessels of the region to he operated upon. But these days different sedative and anaesthetic agents are being used to make the animal desensitize from all external stimuli. These drugs are available in volatile, nonvolatile and gaseous forms. The usage of anaesthetic agent entirely depends upon the species, age, weight, temperament of the patient, nature of the operation to he performed, cost and availability of the drug.
In this project three different combinations were tried in thirty animals of equine species to find out the best selection for major surgical interventions. The animals were divided into three groups often animal each. These groups were designated as Group A, B and C. Group A was anaesthetized with XylazineiPentothal sodium, Group B with Acepromazine/Pentothal sodium and Group C with Diazepam/Pentothal sodium. The efficacy of these combinations was measured on the basis of nature of induction, recumbency period, nature of recovery, different body reflexes, recording temperature, pulse, respiration, and statistical analysis of results.
The analysis of the results collected during this study clearly indicated that a combination of cliazepam with pentothal sodium was a better selection for anaesthetizing equine patients. This study aslo proved that combination comprising of xylazine and pentothal sodium could he used for minor surgical interventions as it produced light surgical anaesthesia.
It was concluded that a combination consisting of diazepam and pentothal sodium should be used for all types of major surgical procedures in equine practice.

Publisher: 2000Dissertation note: There are different joint problems in dogs but out of all the incidence of hip joint problems is higher. There are different problems of hip joint mainly, hip dysplasia, leg-calve-perthes disease, degenerative joint disease, irreparable fracture of acetabulum, femoral head and neck. Different methods are used as a treatment for above mentioned ailments. The methods used for such type of problems are categorized into conservative, palliative and surgical.
The surgical treatment is further divided into (1) salvage procedure i.e. femoral head and neck excision (2) total hip replacement.
The present project was launched to find out the efficacy of two approaches used for the femoral head and neck excision in dogs. The study was conducted on 18 mongrel dogs of either sex ranging in weight from 20.25 kg, which were divided into three groups of 6 dogs each.
In group A femoral head and neck excision was performed by using craniodorsal approach, whereas in group B ventral approach was used for the same procedure. Group C was kept as control in which the femoral head was luxated by using either approach. All the dogs were kept in kennels for a period of sixteen week and results were collected on the basis of clinical and radiographic evaluations. All the dogs were euthanized at the end of experimental period and operation sites were explored to find out the gross changes and also to find out the evidence of false joint formation in the muscles.
The analysis of results clearly indicated that craniodorsal approach was a better procedure than ventral approach for the femoral head and neck excision in dogs.

Publisher: 2001Dissertation note: Indigenous chicken are the most commonly kept domestic animals in Pakistan and there are many large collections of this species at home and farm level. The demand for their veterinary care is increasing and hence the knowledge for the current methods of their restraint and sedation has become the present need.
The study was conducted on thirty clinically healthy male chickens of twelve to sixteen weeks of age and weight ranging from 1000-1200 grams. They were divided into three groups namely Group-A, B and C comprising ten chicken each. Each group was divided into subgroups i.e Al, A2, Bi, B2, & Cl, C2. To study the effect of surgical stress, castration was performed on birds of subgroup A2, B2 and 02. Birds of the three groups A, B, and C were anaesthelized with ketamine HOl @20 mg/kg body weight, kelarnine 1-101 (@ 20 mg/kg body weight) + xylazine HCL (@ 2mg/kg body weight) and ketamine HCL (@ 25 mg/kg body weight) ± Diazepam (@ 2.5 mg/kg body weight) intramuscularly, respectively.
After getting anaesthesia, the effects on various body reflexes were recorded in order to assess the induction and surgical stage longevity. The time taken by Ketamine 1-101 to induce anaesthesia was 3.6±0.22 minutes. Katamine 1-IC1 induced anaesthesia persisted upto 17 ±0.88 minutes with the presence of corneal, palpebral and wing stretching reflexes. The birds took 59.5±2.90 minutes to recover. Ketamine HCI/ Xylazine HC1 took 9.6±0.58 minutes to induce anaesthesia which persisted for 30± 1.84 minutes with almost complete absence of all reflexes. The birds took 90.4±9.61 minutes to stand on their feet. Ketamine HCL/Diazepam induced anaesthesia within 5 ±0.33 minutes for 38± 1.12 minutes with almost absence of corneal, palpebral, wing stretching and mandibular tone reflexes. The birds recovered after 162.4± 10.76 minutes.
The analgesia & muscle relaxation was very poor in group A as the birds of subgroup A2 exhibited severe pain and resentment when they underwent caponization. It was very good in group B & there was almost complete absence of all reflexes during surgical anaesthesia so caponization was easily performed on birds of subgroup-B2. However in group C, some birds showed unwanted movements (Excitement, shivering, backward pulling of neck) during the procedure.
The results of this study clearly indicated that the combination comprising Ketamine HCI and Xylazine HC1 proved to be an ideal cocktail to induce anaesthesia in the chicken. The study also proved that combination provided maximal analgesia which is normally required for a major surgical intervention. The said combination provided excellent muscle relaxation with smooth induction and recovery. It was also concluded that cocktail consisting of Ketamine HC1 and Diazepam can effectively be recommended for minor surgical exercises.

Publisher: 2002Dissertation note: Mandibular fractures in dogs mostly occur as a result of road accidents, usually due to hit by vehicle and during dental extractions. Immobilization is essential and must resist the stresses of eating and chewing.
Different techniques have been established in the past for the repair of mandibular fractures such as bone plating, wiring, pinning, use of K.E. apparatus, use of lag screw for repairing symphyseal fracture and application of tape muzzle. Among the above mentioned techniques bone plating and wiring are frequently used methods for repairing mandibular body fracture in dogs.
The present project was designed to compare the two techniques i.e. plating and wiring for the repair of mandibular fracture in dogs.
Study was conducted on twelve adult dogs, which were divided into two groups i.e. A and B, comprising six animals each. In group A, fracture was repaired with Auto Compression Plate and in group 13, with stainless steel wire. The dogs of group A were numbered from 1 to 6 and those of group B from 7 to 12 for identification purpose.
All the experimental dogs were kept over a period of three months post-operatively at Surgery Section, College of Veterinary Sciences, Lahore. Different parameters were studied to select the best technique for the repair of mandibular fracture in dogs. These parameters were as under:
1. Physical examination
2. Radiographic evaluation
3. Post-Euthanasia examination
The analysis of the results clearly indicated that the use of hone plating was a better option over wiring for the repair of mandibular fracture.

Publisher: 2002Dissertation note: Diseases of gastro-intestinal tract like intestinal foreign body, intussusception with obstruction and adhesion, gangrene, volvulus and abdominal trauma amenable to surgical correction with enterectomy, segmental resection and end-to-end anastomosis had been a nightmare with both human and veterinary surgeons. Most of the techniques evolved in the past were not commensurate with the criteria of physiological restoration of normality, absence of leakage and minimal lumen stenosis. The present study was undertaken to compare the three suturing techniques viz; simple interrupted crushing sutures, simple interrupted lembert sutures and simple continuous lembert sutures for end-to-end anastomosis. Study was conducted on 12 clinically healthy dogs of mixed breed divided equally into three groups.
The versatility and comparison of the techniques were evaluated on the basis of clinical parameters, hematological value, radiographic examination and postmortem findings.
It was observed that simple interrupted crushing technique was comparatively more compatible and superior due to its simplicity, economical, less lumen reduction as compared to other techniques viz; simple interrupted Lembert technique and simple continuous Lembert technique.
The results of this study clearly indicated that the use of simple interrupted crushing sutures has an edge over the simple interrupted lembert suture and simple continuous lembert sutures for end-to-end anastomosis of jejunum in dogs.

Publisher: 2003Dissertation note: Certain diseased conditions like renal calculi, renal cyst, malignant tumors, trauma, congenital anomalies, immune mediated, genetic, aging, poisoning, bacteria, virus and parasite leads to loss of partial or complete renal activity. This loss is usually irreversible so partial or complete removal of damaged kidney is necessary to save the animal from these life threatening conditions.
The present study was undertaken to ensure the effects of partial and complete nephrectomy on various blood parameters. The purpose of any surgical procedure is restoration of normal anatomy and rapid return of function. For this purpose, partial nephrectomy and complete nephrectomy was experienced in group A and B, comprising 4 animals each.
Effects of both the techniques were evaluated on the basis of clinical parameters, blood chemistry, hematological findings, radiographic examination and histopathological findings.
It was observed that both the techniques are effective to save the life of animal but in completely nephrectomized dogs the values observed at different intervals i.e. 1S 4th and 8th post-operative week were recorded high. Two animals from group A were kept for longer duration i.e. 4 months in which all the values were in normal limits when tested after 4 months. On the other hand, partially nephrectomized dogs in group B showed normal clinical, biochemical and hematological values at the end of experimental period i.e. 8th week.
Hence, it is concluded that loss of partial or complete function of one kidney is compensated by the contra lateral organ in the presence or by removal of damaged partner. Research has proved that both the techniques (complete and partial nephrectomy) do not bring any significant change in the biochemistry of the animal so that these techniques can be tried to save the life of patient in proportion to the extent of defect.

Publisher: 2003Dissertation note: The present project was designed t find out most effective and accurate method of internal fixation in avian long oblique tibiotarsal fracture repair. For this purpose 12 indigenous chickens of both sexes were selected and randomly divided into three groups i.e. A, B and C comprising four birds each. Long oblique tibiotarsal fractures were created in either of the limb. In group A these fractures were repaired with single intramedullaiy pin. K.E. wire f 2.5mm diameter was used for this purpose. In group B, 2 - 3 full cerclage wires were applied where as both these techniques were used simultaneously in the birds of group C to achieve the goal of fracture stabilization. The birds were kept uptil 8 weeks post operatively. The fracture healing procedure was monitored on weekly basis. The birds were slaughtered at the end of experiments period and postmortem examination was conducted to see the gross lesion over the fracture site. The data thus obtained from the results revealed that the use of single intra medullaiy pin along with 2 - 3 full cerciage wire application showed an excellent and smooth healing potential for the repair of long oblique tibiotarsal fracture.

; Nature of contents: ; Literary form: Publisher: 2005Dissertation note: Ovariohysterctomy is one of the most commonly performed operation in cats and is indicated for both medical and behavioral reasons. The most common indication of ovariohysterectomy is elective sterilization which avoids all objectionable sexual behaviors and over population. Ovariohysterectomy is the treatment of choice for most uterine diseases and it greatly reduces risk of mammary neoplasia. The method of performing ovariohysterectomy in cats must be affordable, safe, reliable & convenient. In the past different approaches have been tried for ovariohysterctomy in cats viz. linea alba(ventral midline) and vertical flank. But the relative efficacy of the approaches has not been determined in the past in our conditions. The objective of our study is to compare and evaluate these two approaches in our environmental conditions. The Flank approach was found to be relatively better than the Ventral midline approach in our conditions in terms of convenience, reliability, safety with rapid recovery and less postoperative complications.

Publisher: 2007Dissertation note: Stomach is important and biggest dilatation of alimentary canal which mainly serves the purpose of digestion of food. The stomach has two extremities cardia and pylorus, it also has fundus and body. The pyloric extremity is connected with the duodenum by pyloric canal. The gastric emptying of food is controlled by pyloric sphincter. Many problem have been diagnosed in the pylorus such as gastric and duodenal ulcers, neoplaisa, chronic gastritis, drugs and chemicals resulting in pyloric stenosis. Various surgical attempts were made in the past to treat such problems, these includes pyloromyotomy, pyloroplasty, transverse and YU advancement pyloroplasty and partial or complete pylorectomy.
Keeping in view the importance of this part of stomach two surgical procedures were tried Transverse pyloroplasty and YU advancement pyloroplasty as a solution to the obstructive problems of the pylorus. Although these techniques are well established methods and have been used by the various surgeons in the past as a remedy to the stenotic problems of the pylorus but no work has been done on comparative efficacy of these two procedures concerned.
The present project was designed to study the comparative efficacy of these two techniques. Twelve healthy mongrel dogs were selected and were divided into three groups comprising four animals each.ln group A Transverse Pyloroplasty , in group B YU Advancement Pyloroplasty was performed and dogs of C group were kept as control. The efficacy of the procedures was evaluated on basis of physical examination, radiographic evaluation, and postmortem examination.
Laparotomy was performed in aseptic condition and pylorus was exteriorized in both the groups. In dogs of group A, longitudinal incision was given over the pylorus which was closed in transversed fashion. After checking any leakage at the operated site the abdomen was closed in routine manner. In group B, Y shaped incision was given at the pylorus which was converted into U. Dogs of group C were kept as control and they were not subjected to any surgical procedure.
Barium study procedure was performed in the dogs of all groups to estimate the rate of gastric emptying and post mortem was preformed to evaluate the change in diameter of the pylorus.
The results of this study clearly indicated that although both the techniques are effective in increasing the diameter and improving the gastric emptying but Y U Advancement Pyloroplasty was more useful and effective procedure.
