Lipoma Removal Surgery in White-Rumped Shama (Kittacincla malabarica macraoura)

Lipoma in birds is a benign tumor of adipose cells that often occurs in the subcutaneous area. White-rumped shama, more than three years old, was rushed to the puskesmas with symptoms of decreased activity and singing ability. The results of the examination were two round, multi-focal masses, firmly demarcated, yellowish in color with a soft, chewy consistency measuring ± 4 x 2 x 1 cm on the chest and ± 1 x 1 x 1 cm. in the abdominal area, firmly attached to the subcutaneous layer since six months ago, and getting bigger. The feathers around the mass are shed and vascularized on the surface of the mass. Surgery was performed because the mass suspected of being a tumor growing rapidly and causing pain. It was fasted two hours before surgery and the anesthetic used was a combination of ketamine HCl and xylazine. Postoperative therapy using the antibiotic enrofloxacin, ketoprofen analgesics, 0.9% NaCl fluid therapy and topical antibiotic gentamicin ointment. The tumor that has been successfully removed is yellowish in color with several areas of hyperemia and an oily surface. The results of histopathological examination characterized by the presence of adipose cells that appeared to proliferate well confirmed that the tumor was a lipoma.

Evaluation of Clinico-physiological Effects of Ketamine Alone and in Combination with Dexmedetomidine or Butorphanol in Atropinized Dogs

Background: Ketamine is rarely used alone because of its association with poor muscle relaxation, tachycardia, catalepsy or muscle rigidity and therefore commonly used in combination with alpha 2 agonist or opioid to minimize the untoward effects. The aim of the present anaesthetic study was to evaluate the clinico-physiological effects of ketamine alone and in combination with dexmedetomidine or butorphanol for inducing adequate anaesthesia in dogs. Methods: The present anaesthetic study was conducted on 18 (eighteen) healthy dogs of either sex and randomly divided into three groups (K, DK and BK) with six animals in each group. Atropine sulphate @ 0.04 mg/ kg was administered intramuscularly 15 minutes prior to anaesthetic study to all the animals. In group K, ketamine HCl alone was administered @ 5 mg/kg by slow i/v and kept as control. In group DK and BK, after administration of atropine sulphate 15 minutes later dexmedetomidine @ 10 µg/kg i/m and butorphanol @ 0.2 mg/kg i/m were administered respectively. Ten minutes later ketamine HCl was administered @ 5 mg/kg slowly intravenously in both group DK and BK to induce surgical stage of general anaesthesia. The following clinical parameters were recorded viz., onset of sedation, onset of anaesthesia, degree of analgesia, extent of muscle relaxation, duration of anaesthesia and complete recovery. The physiological parameters (rectal temperature, heart rate and respiratory rate) were recorded before anaesthetic study at 0 min. and at 10 minutes after preanaesthetic administration and then at 10, 20, 40, 60, 90, 120 and 180 minutes after ketamine anaesthesia. All the data were analyzed using SPSS v 15.0 statistics software program and presented as mean±Standard Error. Result: The onset of sedation was quicker in group DK followed by group K and BK. Duration of anaesthesia and complete recovery in group DK was significantly (p less than 0.01) longer than in group K and BK. The degree of analgesia was excellent in group DK and good in group K and BK. The extent of muscle relaxation was excellent in group DK, good in group BK and was poor in group K. The physiological parameters showed transient changes which compensated and remained within normal range during the observation period. The above anaesthetic study suggests that ketamine in combination with dexmedetomidine or butorphanol can be safely used for inducing adequate anaesthesia in dogs. However, dexmedetomidine-ketamine can be used safely for longer duration of surgical procedures in dogs.

Chemical immobilisation of a Eurasian Lynx Lynx lynx (Linnaeus, 1758) (Mammalia: Carnivora: Felidae) with ketamine-dexmedetomidine mixture in Ladakh, India

Limited information is available regarding the ecology and conservation of the Eurasian Lynx Lynx lynx in the Himalaya. We report the first rescue and chemical immobilisation of a Eurasian Lynx in Ladakh, India. A female individual was successfully immobilized intramuscularly with a mixture of ketamine Hcl and dexmedetomidine using a dose rate of 5 mg/kg body weight and 0.03 mg/kg body weight, respectively. Dexmedomidine was antagonised with atepamezole through intramuscular route. The current information on the drug mixture does not account for variations within sub-populations for intrinsic or external factors and needs dedicated studies with large sample sizes and different drug mixtures.

Report: The effects of topical pleurotus tuberregium (PT) aqueous extract on intraocular pressure in monkeys

Purpose In earlier experiments in Nigeria, aqueous extract of Pleurotus tuber-regium (PT) had been shown to lower intra ocular pressure (IOP) in a feline model. The aim of the current study was to determine whether PT had the same or a similar IOP-lowering effect in ocularly normal non-human primates. Methods Four monkeys were treated twice daily for 4 days with 2 x 20 μl drops of 50 mg/ml PT (pH = 4.3). The monkeys were sedated with 5–10 mg/kg ketamine HCl IM. PT was administered to the right eye and BSS to the left eye. Baseline IOP was measured just prior to beginning treatment, and on day 5 before treatment and then hourly for 3 hours, beginning 1 hour after treatment. SLEs were performed at baseline and on day 5 pre- and 3 hours post-treatment. Results There was no significant difference between IOP in treated vs control eyes in the protocol. There were no adverse effects or toxicity as seen by SLE. Conclusions The inability of the extract to lower IOP in monkeys, in contrast to ocular hypertensive cats in an earlier study, could be due to species differences or duration of treatment. Since no adverse effects were observed in the monkeys, further studies with varying durations and dosages are recommended.

The Effects of Ketamine on the Gut Microbiome on CD1 Mice

The intestinal microbiota of an organism can significantly alter outcome data in otherwise identical experiments. Occasionally,animals may require sedation or anesthesia for scientific or health-related purposes, and certain anesthetics, suchas ketamine, can profoundly affect the gastrointestinal system. While many factors can alter the gut microbiome (GM), theeffects of anesthetics on the composition or diversity of the GM have not been established. The goal of the current study wasto determine whether daily administration of ketamine would significantly alter the microbiome of CD1 mice. To achievethis goal, female CD1 mice received daily injections of ketamine HCl (100 mg/kg) or the equivalent volume of 0.9% salinefor 10 consecutive days. Fecal samples were collected before the first administration and 24 h after the final dose of eitherketamine or saline. Samples were analyzed by 16S rRNA sequencing to identify changes between groups in diversity orcomposition of GM. The study found no significant changes to the GM after serial ketamine administration when treatedmice were housed with controls. Therefore, ketamine administration is unlikely to alter the GM of a CD1 mouse and should not serve be a confounding factor in reproducibility of research.

A BIOCHEMICAL STUDY OF DIAZEPAM AS A PRE-ANESTHETIC IN COMBINATION WITH VARIOUS ANESTHETICS DURING ORCHIDECTOMY IN DOGS

Diazepam as a Pre-anesthetic with Propofol or Ketamine HCl has vital combinations for the induction of anesthesia in dogs. The main objective of the study was to provide cost effective and safest injectable anesthetic cocktail for induction of anesthesia in dogs and to evaluate undesired effects on liver and kidneys of the anesthetic agent. Experimental dogs (n=12) were placed equally in two groups (A and B). Each animal from group A was administer Diazepam with Propofol blend while that of group B was given Diazepam with Ketamine HCl. Orchidectomy was performed as per standard protocols for considering as a pain module. Physical parameters like temperature (P>0.05), pulse (P<0.05) and respiration (P<0.05) and Biochemical parameters like Renal (P>0.05) and liver functioning test (P<0.05) were performed. This research reveals that Diazepam with Ketamine HCl depicts better results over Diazepam with Propofol. It can be concluded that Diazepam with Ketamine HCl shows a safe, cost effective, ideal and easily obtainable anesthesia with least drastic hazards over kidney and liver. So, Diazepam in combination with Ketamine HCl can be used for induction of anesthesia and to execute major as well as minor surgical exercises on dogs.

Efficacy of Ketamine Hcl and Tramadol Hcl by epidural route for lower abdominal surgeries

Background: Pain pathway has profound implications for management of acute pain and provoked interest in the use of pre-emptive analgesia and new methods of postoperative pain management with new agents like opioid and non-opioid drugs either independently or in combination. The objective of the study was to study efficacy of Ketamine Hcl and Tramadol Hcl (preservative free) by epidural route for lower abdominal surgeries.Methods: This study has been conducted on hundred patients in the age group of 20 to 50 years. These patients have undergone various lower abdominal surgeries, gynecological and surgical procedures. Failed epidurals, catheter kinking, catheter migration and dural puncture cases are excluded from the study. The patients were divided into two groups namely Group-A and Group-B, with 50 patients in each group.Results: Both groups were similar in terms of age, sex and weight. In Group-A patients who received 30 mg of Ketamine, the mean time of onset of analgesia being 17.01+2.65 minutes compared to 12.18+2.28 minutes in Group -B patients who received 100 mg of tramadol, In Group-A the mean time of duration of analgesia is 6.75+0.46 hours compared to 9.36+0.84 hours in Group-B. Nausea and vomiting (24% vs. 2%), urinary retention (4% vs. 2%) was more in group B compared to group A patients. Backache was equal in both the group patients (6% vs. 6%). Pain on injection more in group A patients i.e. 8% compared to only 2% in patients who belonged to group B.Conclusions: Epidural tramadol is superior to epidural ketamine for postoperative pain relief.
