Comparative Efficacy Of Advanced Surgical Hemostats In The Canine Hepatotomy

by Syed Waseem Abbas Ali Shah (2009-VA-168) | Dr. Hamid Akbar | Prof. Dr. M.Arif Khan | Dr. Muti -ur- Rehman Khan.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: The liver is a very complex and largest organ of the body. It has role in body metabolism, filtration of blood, synthesis of plasma protein, hormone production, and it is most vital organ of body. The liver has an excellent ability to recover from injury and regenerate new tissues. Liver is a highly vascularized organ and chances of bleeding are very high in hepatic surgeries. Liver is directly supplied by hepatic artery and drained by portal vein. We often come across certain problems in liver which require surgery. When an incision is given in liver there is a high risk of bleeding. In severe cases animal can lead to death due to hypovolemic shock. In this study we used latest and most advanced hemostatic agents by using Surgicel Snow and Surgicel Fibrillar to control bleeding during hepatotomy in dogs. These hemostats are affordable, safe, reliable and convenient. Considering the significance of hemostasis in surgical interventions, this project was designed to compare the advance hemostatic agents e.g. Surgicel Snow, Surgicel Fibrillar and sterile Surgical Gauzes. This study helped us to identify the best method that can be used for future surgical interventions in dogs, with the aim to minimize surgical bleeding in liver surgeries to accentuate early recovery. Conclusion On the basis of findings of this study: it was concluded Surgicel Snow is best hemostat than Surgical Fibrillar. It is the best hemostat with minimum blood loss and least effects on liver function. Availability: Items available for loan: UVAS Library [Call number: 2658-T] (1).

Effect Of Unilateral And Bilateral Thyroidectomy On Hormonal And Biochemical Parameters In Dogs

by Mehmood Ur Rehman (2009-VA-177) | Dr. Hamid Akbar | Prof. Dr.M.Arif Khan | Dr. Muti ur Rehman Khan.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Thyroid gland is one of the most important endocrine gland of animal body. T3 and T4 are two major hormones secreted by thyroid gland. These hormones have a major role in metabolism of cells and organs. In normal thyroid both these hormones have anabolic effect. Thyroid tumors account for 1.2-3.8 % of all types of tumors in dogs. Unilateral, bilateral or subtotal thyroidectomies are practiced to remove benign or malignant thyroid carcinomas. The present study was conducted on 12 mongrel dogs. These dogs were rendered to 3 groups with 4 dogs in each group. One group acted as control, in which no surgery was performed, second group underwent unilateral removal of thyroid gland while the third group underwent bilateral removal of thyroid gland. Free thyroxine, thyroid stimulating hormone level, calcium, W.B.Cs, R.B.Cs and haemoglobin concentration were monitored for 21 days post-operatively. The data was expressed as mean and standard deviation. Results of the study were analysed by 2 samples T-test, one way ANOVA using multiple comparison test on SPSS version 16.0. Based on these results it was concluded that bilateral thyroidectomy was effective in relieving hyperthyroidism but there is a need to immediately initiate levothyroxine therapy. Free T4 level drops near to zero by day 21 and TSH level rises by many folds. On the other hand, in unilateral procedure Free T4 level remain in normal range and 75% of dogs require no levothyroxine therapy. Level of calcium in unilateral and bilateral thyroid removal remains within normal range provided parathyroid glands are preserved properly. Haemoglobin concentration in both the procedures is reduced significantly postoperatively. There is a need to monitor blood parameters postoperatively.

Comparative Efficacy Of Xylocaine Hcl And Bupivacaine Hcl For Ophthalmic Anesthesia In Horses

by Muhammad Asad Islam (2012-VA-576) | Dr. Sadaf Aslam | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Sarwar Khan.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Ophthalmic procedures can be performed by many clinicians in horses using local nerve blocks by using local anaesthetics for short duration of action for completion of these procedures. These surgical procedures may involve exclusion of third eyelid, suturing of laceration around eye orbit and tumor which can be caused due to any reason with in time period of thirty minutes. Inner chamber centesis can be done easily by using the above mentioned technique in standing horse. There are numerous benefits of doing standing surgical methods and avoiding general anaesthesia in horses. As hospitalizing horse may get other infectious diseases from surroundings like colitis and laminitis and also injured it when recovering from general anaesthesia. On the other hand standing surgical procedure reduced such complication by using local anaesthetic for short duration. Bupivacaine Hcl gave an ideal local eye anaesthesia compare to xylocaine Hcl for standing surgical procedures in horses. The present study was accomplished to assess the effectiveness of two local eye anaesthetics; xylocaine Hcl and bupivacaine Hcl by two different techniques i.e. retrobulbar technique and auriculopalpebral technique in horses. A total of 12 horses from indoor clinic and S.P.C.A were used in this study. These horses were subjected to two groups’ i.e. Group A and B. Each of these groups was further subdivided into two subgroups i.e. Group AI, AII and BI, BII respectively. SUMMARY 42 Horses in group A were administered xylocaine Hcl through auriculopalpebral technique and retrobulbar technique. While horses of subgroup AI were given xylocaine Hcl by auriculopalpebral technique and horses in subgroup AII were injected xylocaine Hcl by retrobulbar technique. Likewise horses in subgroup BI were given bupivacaine Hcl by auriculopalpebral technique, while those of subgroup BII were given bupivacaine Hcl through retrobulbar technique. The efficacy of above mentioned local anaesthetics was compared on the basis of Pattern of induction, Duration of anaesthesia and Recovery Pattern. Presence or absence of reflexes was also noted i.e. Pupillary Light Reflex and Blink reflex. The data were analyzed through one way analysis of variance (ANOVA). The difference in group’s means was determined by Least Significant Difference (LSD) post-hoc test. A probability level of (P<0.05) was considered as statistically significantly difference. The statistical analysis was performed using statistical package for social science (SPSS) version16. Availability: Items available for loan: UVAS Library [Call number: 2679-T] (1).
