Abstract:
هدفت الدراسة الى تقييم استخدام الكيتامين (K)، والترامادول (T)، والباراسيتامول (P) والزيلازين (X) كبرامج تخدير للاغنام باستخدام جرعات مختلفة وطرق اعطاء مختلفة. استخدم في التجربة ثلاثون من الاغنام الكبار البالغة من السلالة المحلية (تراوحت معدل اوزانها 27.4 | The study aim to evaluate the use of ketamine (K), tramadol (T), paracetamol (P) and xylazine (X) as an anesthetic protocol for anesthesia in sheep by using different doses and different routes of administration. Thirty animals of adult local breed sheep weighing (27.4±2.46) kg were used in 6 different anesthetic protocols. The animals were divided into six groups (5 animals of each). The first three groups (without using of xylazine) were giving the drugs by IV injection in the jugular vein : G1 giving K4 and P10 mg/kg IV, G2 giving K4T2 mg/kg IV, and G3 giving K4 T2 P10 IV. In the other groups (G4, G5, and G6) xylazine were adding to the anesthetic protocol. G4 giving K4 T2 P10 X0.05 by IV route. G5 was giving K10 T2 P10 X1 mg/kg by IM route and G6 giving K20 T4 P10 X2.5 mg/kg by IM route. The HR, RR, RT, muscle relaxation, limb, and flank analgesia, and rumen movement were taken before administration of anesthesia (time 0) and consider as the control reading. Then taken at 5, 10, 15, 20, 30, 45 and 60 minutes or till the end of anesthesia. In the IV groups (without using of xylazine), (G1, G2, and G3). The induction time was 53.2, 60, and 68 seconds, the surgical anesthesia was 2.8, 5, and 5 minutes, and the total recovery time was 4.8, 5.4, and 3 minutes in G1, G2 and G3 respectivily. The RR, and HR were increased, and the RT was decreased. The muscle relaxation was mild, and the analgesia was moderate. In G4 after adding of xylazine and giving the anesthetic protocol by IV route, the induction time, the surgical anesthesia, and the total recovery time were become 50.6 seconds, 23 minutes, and 9.4 minutes respectively. The HR, RR, and RT were increased, the muscle relaxation, and analgesia were moderate. In G5 after increased the dose of ketamine and xylazine and giving the anesthetic protocol by IM route, the induction time, the surgical anesthesia, and the total recovery time were 5, 36, and 5.6 minutes respectively. The HR and RR were decreased, and the RT was increased. The muscle relaxation was deep for 10 minutes, and the analgesia was moderate for 10 minutes also. In G6 after doubling the ketamine, tramadol, and xylazine doses, and giving the anesthetic protocol by IM route. The induction time, the surgical anesthesia, and the total recovery time were 3.6, 73.4, and 7 minutes respectively. The HR started stable, then after 15 minutes decreased sharply, The RR was irregular, with apnea, the RT was increased, the muscle relaxation was deep for 35 minutes, and the analgesia was deep for 45 minutes. In conclusion the addition of tramadol and paracetamol to the ketamine anesthesia of sheep in low doses, improve the induction and recovery time of anesthesia, without increase the duration and depth of anesthesia. Adding of xylazine to the anesthetic protocols increase the duration and depth of anesthesia. The protocol of K10 T2 P10 X1 by the IM route is the best protocol dose among the six protocols used in this study.
