Quiz: Are You Prepared to Confront Animal Bites?

Richard H. Sinert, DO

August 18, 2015

Determining the exact incidence of animal bite wounds in the United States is difficult, because many are never reported. Each year, an estimated 4.5 million dog bites occur, which result in hundreds of thousands of emergency department visits. Do you know the concerns associated with such injuries and how best to treat them? Test yourself with this short quiz.

以下哪种咬伤最常见于狗咬伤?

Which of the following types of bites are a most often associated with dogs?

答案:挤压型咬伤 Crush-type bite

The bite of a dog can yield between 150-450 lb of pressure per square inch, depending on the dog and its training. Therefore, although a dog bite may appear as a laceration or avulsion, it most likely has components of a crush injury. In this type of injury, debridement is required to remove any crushed tissues. Once debrided, the laceration injury is then amenable to suturing and primary closure.

根据犬的种类及其接受的训练不同,犬类撕咬的力量大约为每平方英寸150-450磅。因此,尽管犬咬伤可以表现为撕裂伤或撕脱伤,但更可能为挤压伤。对于挤压伤而言,需要进行清创以清除所有受累组织。一旦完成清创,即可对撕裂伤进行修补,缝合伤口并进行一期闭合。

以下哪个部位咬伤感染风险最高?

A bite to which of the following regions carries the highest risk for infection?

答案:手部 The hand

Bites of the hand generally have a high risk for infection because of the relatively poor blood supply of many structures in the hand and anatomical considerations that make adequate cleansing of the wound difficult. In general, the better the vascular supply and the easier the wound is to clean (ie, laceration vs puncture), the lower the risk for infection.

手部咬伤的感染风险通常较高,因为手部很多结构的血流功能相对较差,而且手部的解剖特点造成伤口彻底清创非常困难。总之,血液供应越好,伤口清创(即撕裂伤与穿通伤)就越容易,感染风险就越低。
