Evaluation of Xylazine, Acepromazine and Medetomidine with Ketamine for General Anaesthesia in Rabbits

A randomized, prospective, blinded experimental study was conducted in 32 rabbits of either sex to compare  the anaesthetic and physiological effects of ketamine with different pre-anaesthetics. Rabbits were  randomly divided into 4 equal groups. Xylazine 6 mg/kg in animals of group xylazine-ketamine (XK), acepromazine  2 mg/kg in animals of group acepromazine-ketamine (AK), medetomidine 125 μg/kg in group  medetomidine-ketamine 1 (MK1) or medetomidine 250 μg/kg in group medetomidine-ketamine 2 (MK2)  were administered by intramuscular injection (IM). Five minutes later, ketamine 60 mg/kg was administered  intramuscularly to all the groups. The rabbits were observed for the onset of weak time, down time,  the time to loss of righting reflex, pedal reflexes and response to surgical stimuli. Heart rate, respiratory  rate and rectal temperature and arterial oxygen saturation of haemoglobin (SpO2) were recorded up to 60  min. Weak time, down time and time to loss of righting reflex were the shortest in animals of group MK2  as compared to the other groups. Pedal reflexes remained intact in all the animals of XK group, but were  abolished in 50% of the AK group, 75% of the MK1 group and 100% of animals in the MK2 group. Pain  was evinced during surgery by all the animals in group XK, 5 animals in group AK and 4 animals in group  MK1. The best analgesia was achieved in the animals of group MK2, where none of the animals showed  pain on surgical stimulation. Heart rate and SpO2 decreased significantly (P<0.01) in the animals of groups  XK, MK1 and MK2 but respiratory rate and rectal temperature decreased significantly (P<0.01) in all the  groups. However, all the animals recovered from anaesthesia without complications. It was concluded that  medetomidine 250 µg/kg and ketamine 60 mg/kg produced excellent anaesthesia to allow pain free surgery  and may be considered suitable for anaesthesia in New Zealand White rabbits.

Stem cell therapy in animal models of central nervous system (CNS) diseases: therapeutic role, challenges and perspectives

ABSTRACT Many human diseases relating to central nervous system (CNS) are mimicked in animal models to evaluate the efficacy of stem cell therapy. The therapeutic role of stem cells in animal models of CNS diseases include replacement of diseased or degenerated neuron, oligodendrocytes or astrocytes with healthy ones, secretion of neurotrophic factors and delivery of therapeutics/genes. Scaffolds can be utilized for delivering stem cells in brain. Sustained delivery of stem cells, lineage specific differentiation, and enhanced neuronal network integration are the hallmarks of scaffold mediated stem cell delivery in CNS diseases. This review discusses the therapeutic role, challenges and future perspectives of stem cell therapy in animal models of CNS diseases

Prosudba učinka midazolam-ketamina s deksmedetomidinom i fentanilom za injekcijsku anesteziju u pasa.

A prospective randomized blinded study was conducted on 12 clinically healthy adult dogs of both sexes (mean weight of 18.34 ± 0.78 kg) divided into three groups (n = 4). The animals received 0.4 mg/kg midazolam and 10 μg/kg dexmedetomidine (group A), 0.4 mg/kg midazolam and 20 μg/kg dexmedetomidine (group B) and 0.4 mg/kg midazolam + 20 μg/kg dexmedetomidine + 4 μg/kg fentanyl (group C) intramuscularly, using separate syringes. Ten minutes later Ketamine was administered intravenously in all the groups. A significantly (P<0.05) shorter weak time (onset of sedation) and down time (onset of recumbency) were recorded in animals in group C as compared to the animals of groups A and B. Muscle relaxation was excellent in group C. The pedal reflex was abolished up to 30 min in groups A and B and up to 60 min in group C. Intubation was only possible in groups B and C. The anaesthetic induction dose of ketamine was minimal in group C. Standing recovery time was shortest in the animals of group C. Respiratory rate (RR) decreased significantly (P<0.05) throughout the observation period, but rectal temperature (RT) decreased significantly (P<0.05) towards the end of the observation period in all the groups. Heart rate decreased significantly (P<0.05) in the animals of group B. Mean arterial pressure (MAP) was maintained within the physiological range in all the groups. It was concluded that dexmedetomidine (10 μg/kg)-midazolam-ketamine can produce anaesthesia for about 20 min in dogs. Increasing the dose of dexmedetomidine did not enhance the duration of anaesthesia, but the further addition of fentanyl not only reduced the induction dose of ketamine but also increased the duration of anaesthesia up to 50 min. Dexmedetomidine-midazolam-fentanyl-ketamine can be used for prolonged duration of injectable anaesthesia in dogs.Poduzeto je prospektivno istraživanje na 12 slučajno odabranih klinički zdravih pasa i kuja (prosječne tjelesne mase 18,34 ± 0,78 kg) podijeljenih u tri skupine (n = 4). Životinjama skupine A bio je intramuskularno primijenjen midazolam u dozi od 0,4 mg/kg i deksmedetomidin u dozi od 10 μg/kg. Životinjama skupine B bio je i/m primijenjen midazolam u dozi od 0,4 mg/kg i deksmedetomidin 20 μg/kg, a životinje skupine C primile su i/m 0,4 mg/kg midazolama, 20 μg/kg deksmedetomidina i 4 μg/kg fentanila. Deset minuta nakon toga svim je životinjama intravenski bio ubrizgan ketamin. Značajno (P<0,05) kraće vrijeme smirivanja (nastup sedacije) i vrijeme lijeganja ustanovljeno je u životinja skupine C u usporedbi sa skupinama A i B. Opuštanje mišićja bilo je izvrsno u skupini C. Nožni refleks nestao je nakon 30 minuta u skupinama A i B, a nakon 60 minuta u skupini C. Intubacija je bila moguća samo u životinja skupine B i C. Doza ketamina potrebna za početak anestezije bila je najmanja u životinja skupine C. Vrijeme potrebno za ponovno ustajanje bilo je najkraće u životinja skupine C. Frekvencija disanja značajno se smanjila (P<0,05) u čitavom razdoblju promatranja, dok se rektalna temperatura u svih životinja značajno smanjila (P<0,05) na kraju razdoblja promatranja. Frekvencija bila znatno se smanjila (P<0,05) u životinja skupine B. Srednji arterijski tlak bio je u fiziološkim granicama u svih životinja. Može se zaključiti da kombinacija deksmedetomidin (10 μg/kg)-midazolam-ketamin može u pasa dovesti do anestezije za oko 20 minuta. Povećanje doze deksmedetomidina nije povećalo trajanje anestezije. Ipak, daljnja primjena fentanila ne samo da je smanjila početnu dozu ketamina već je povećala trajanje anestezije na 50 minuta. Deksmedetomidin-midazolam-fentanil-ketamin mogu se rabiti za produženo trajanje injekcijske anestezije u pasa

Comparative evaluation of halothane anaesthesia in medetomidine–butorphanol and midazolam–butorphanol premedicated water buffaloes (Bubalus bubalis)

Six clinically healthy male water buffaloes (Bubalus bubalis) 2–3 years of age and weighing 290–325 kg were used for 2 different treatments (H1 andH2). The animals of groupH1 were premedicated with medetomidine (2.5 g/kg, i.v.) and butorphanol (0.05 mg/kg, i.v.), while in groupH2 midazolam (0.25 mg/kg) and butorphanol (0.05 mg/kg) were used intravenously. Induction of anaesthesia was achieved by 5%thiopental sodium inH1 (3.85±0.63 mg/kg) and H2 (6.96 ± 0.45 mg/kg) groups. The anaesthesia was maintained with halothane in 100 % oxygen through a large animal anaesthetic machine. Better analgesia and sedation with a significantly lower dose of thiopental for induction and significantly higher values of sternal recumbency time and standing time were recorded in group H1 than in group H2 , whereas no significant (P > 0.05) difference for the halothane concentration was observed between groups H1 and H2. Significant decrease in heart rate was observed in group H1 whereas it significantly increased in group H2. In both groups, RR decreased during the preanaesthetic period, which increased significantly (P<0.01) after halothane administration. In both groups a significant (P<0.01) fall in RT was recorded from 20 min to the end of observation period. A significant (P < 0.05) fall in MAP was observed in group H1 from 15 min until the end, while in group H2 MAP increased nonsignificantly (P > 0.05) after premedication and a significant (P<0.05) occurredafter thiopental administration. In both groups a significant (P<0.01) increase in CVP and a significant (P<0.01) decrease in SpO2 were observed after premedication which persisted up to 120 min. ECG changes included significant (P<0.01) decrease and increase in QRS amplitudes in groupsH1 andH2 respectively, a significant (P < 0.05) increase in PR interval was recorded at 15 min in group H1, a significant (P<0.05) decrease in PR interval in groupH2 , a significant (P<0.05) decrease in T wave amplitude in groupH1, and a significant (P<0.01) increase in duration of T wave in groupH1 . It is concluded that both combinations can be used safely in buffaloes for surgery of 2 h duration but better sedation, analgesia and muscular relaxation and more dose sparing effect on anaesthetics and shorter recovery times were observed in group H1

Obstructive Urolithiasis in Buffalo Calves and Goats: Incidence and Management

The present study was conducted to acquire detailed information regarding the cases of retention of urine in goats and buffalo calves presented to the Division of Surgery, Referral Veterinary Polyclinic, IVRI-Izatnagar over a period of 8 months. Out of 186 animals presented with the complaint of retention of urine, 82 (44.08 %) were goats and 104 (55.91 %) buffalo calves. A thorough history regarding age, sex, location, feeding, retention type-partial/complete, castration and duration of retention, of all cases was taken. Age of the animals ranged between one and nine months, with young ones being more commonly affected. Gender variations were seen wherein males were mostly affected. More prevalence was found in the extreme summer or winter. Goats castrated at early age were more affected while such observations were not seen in buffalo calves. Cystorrhexis was more common in buffalo calves compared to goats. All the animals were treated on the same day, taken as surgical emergency and tube cystostomy was done. In post-operative period urinary acidifiers were given to dissolve the calculi. Catheter was removed on an average at 13-17 days post surgery after the animals started passing urine normally through the natural orifice, though, in some cases delay in normal urination was observed
