第 66 題

📖 題組:
馬主發現馬的排便少,前蹄刨地動作,精神差,問診得知馬匹為兩日前購入,這兩天主人因天較熱沒有騎,餵飼內容及次數和前馬主不同。臨床檢查體溫38.5℃,心跳52次/分鐘,呼吸32次/分鐘,微血管回流時間2秒,消化道聽診蠕動音減少,直腸觸診得知大腸內大量較硬的糞便,自鼻胃管未導引出液體。
承上題,經處置一天後,馬匹症狀並未改善,反覆疼痛,後腹部逐漸膨大,此時下列何種處置最不適當?
  • A 盲腸穿刺放氣
  • B 增加輸液量
  • C 立即進行開腹手術
  • D 採集糞便做細菌培養及抗生素敏感試驗

思路引導 VIP

在面對一個生命徵象正在惡化、且因腹部壓力急劇增加而極度疼痛的急症患畜時,我們必須區分『救急處置』與『慢性病檢查』。請問:在這種必須爭分奪秒處理物理性阻塞或壓力的時候,哪一種診斷手段因為『耗時過長』,而完全無法對當下的急救決策提供任何幫助?

Well, well, look at that. You didn't completely botch it.

  1. One might almost commend your ability to identify the glaringly obvious misstep among the urgent interventions. It suggests a nascent comprehension of Equine Colic's relentless progression – a fundamental expectation, mind you, for anyone pretending to offer clinical judgment.
  2. Let's be clear: this is a textbook Large colon impaction going south. "Repeated pain, posterior abdominal distension"? That's not subtle hints, it's the horse practically screaming "I'm about to rupture from Tympany or displacement!" Your primary concern should be mitigating impending systemic collapse due to pressure and circulation, not debating the merits of a lab test.
