動物手術(shù)保溫與動物倫理和福利

瀏覽次數(shù):3869 發(fā)布日期:2017-5-27  來源:本站 僅供參考,謝絕轉(zhuǎn)載,否則責任自負

動物術(shù)中和術(shù)后保溫是動物實驗過程中的一個至關(guān)重要的環(huán)節(jié),是否做好保溫措施直接關(guān)系到實驗的成敗,同時也是科研工作者在進行生命科學相關(guān)研究中將實驗動物倫理和福利付諸實踐的真正體現(xiàn),是對動物愛心的社會責任感的體現(xiàn)。善待活著的動物,減少動物死亡的痛苦。。

動物手術(shù)保溫的科學價值

Responsible scientists know that good science and good animal care go hand in hand, and would not tolerate cruel or inhumane treatment of any laboratory animal.

------The U.S. Animal Welfare Act

美國動物福利法案申明指出“負責的科學家深知,好科學與善待動物是相輔相成的,我們不能容忍殘殺或不人道的對待任何實驗動物!

保障動物實驗結(jié)果準確性:科研效果更好、結(jié)果可信、更加客觀真實

動物手術(shù)低體溫的危害

為什么需要對手術(shù)動物進行保溫?

  1. 損害機體免疫功能,減少皮膚血流和氧供,增加傷口感染率

  2. 降低血流循環(huán)和血液指標,導致凝血發(fā)生,非常不利于血液或血流相關(guān)指標監(jiān)測和測定,比如測量血流量、血壓等

  3. 降低藥物在機體組織中的代謝速度,影響機體代謝

  4. 延長麻醉恢復時間,可能明顯增加動物死亡率

  5. 引起其他疾病的發(fā)生,比如心血管并發(fā)癥

  6. 無法得到真實或接近真實的實驗數(shù)據(jù)

  7. More………

動物手術(shù)低體溫的常見原因

  • 1.麻醉劑的作用:麻醉劑導致擴張血管、抑制體溫調(diào)節(jié),從而導致體溫下降

  • 2.手術(shù)室的低溫環(huán)境,尤其是普通動物室實驗環(huán)境

  • 3.手術(shù)臺的“冷”材質(zhì),比如不銹鋼、樹脂材質(zhì)的臺面

  • 4.長時間藥物注射:長時間輸入與環(huán)境等溫的液體,對動物體液造成“冷稀釋”作用,從而導致動物體溫下降

  • 5.皮膚消毒劑的使用,尤其是裸露皮膚大面積的消毒,導致體內(nèi)熱量散失

  • 長時間的手術(shù)

  • 6.創(chuàng)傷較大的開胸、開腹手術(shù),造成熱量散發(fā)較多

  • 7.動物自身年齡、疾病因素,如營養(yǎng)不良、腫瘤模型手術(shù)

  • Others………


 

動物手術(shù)保溫的常見措施

Solution 1

Solution 2

動物手術(shù)保溫的規(guī)范操作

術(shù)中

1.如果使用電熱毯保溫方式,切忌電熱毯直接放置于不銹鋼、樹脂等“冷”材質(zhì)手術(shù)臺面,因這些材質(zhì)傳熱會導致電熱毯加熱很慢甚至無法升溫到預期溫度;
2.除手術(shù)部位外,其他部位盡量不暴露,可以使用布巾遮蓋;
3.如果是注射液體或藥物,且實驗時間較長,必要時,可以同時對輸進動物體內(nèi)的液體進行預熱;
4.手術(shù)操作配合熟練,減少手術(shù)時間;
5.注意體溫監(jiān)測。


術(shù)后

  • 繼續(xù)將動物放于保溫毯或保溫臺上,待動物恢復。
