离世后，身体会出现哪些变化

What happens to the body after death

心跳停止后，身体会在几小时内经历一连串自然变化，了解它们能避免你误以为“是不是还没走”。先是肌肉全部放松，所以下巴可能张开、舌头吐出、眼睑闭不紧；体温开始慢慢下降，平时暖乎乎的肚皮和耳尖会先变凉。

After the heart stops, the body goes through natural changes over the next hours. Muscles relax, so the jaw may open, the tongue may show and the eyelids may not fully close. Body temperature begins to fall, and the warm belly and ear tips cool first.

大约在两到四个小时后，身体会逐渐变得僵硬，这就是尸僵，通常从眼睑和下颌开始，再蔓延到四肢；一到两天后又会自行缓解。它出现的时间受环境温度和体型影响——天冷、体型小会来得更快。

Roughly two to four hours later, rigor mortis begins, usually in the eyelids and jaw before spreading to the limbs, then easing again after a day or two. Temperature and size affect timing; cold conditions and small bodies move faster.

怎样安全地降温、暂存

How to cool and keep the body safely

如果不能马上接走，降温是为了放慢自然变化，而不是让它“保鲜”。最稳妥的做法是：先用一条毛巾轻轻包住，再放进防漏的袋子或裹上防水布，然后移到家里最凉快的地方，条件允许时放进冰箱冷藏（不是冷冻），下面垫一个托盘防止渗漏。

If collection cannot happen immediately, cooling slows natural changes rather than preserving the body. Wrap it gently in a towel, place it in a leak-proof bag or waterproof layer, move it to the coolest spot, and refrigerate rather than freeze when possible, with a tray underneath.

• 不要直接把冰块贴在皮毛上，用毛巾隔开，避免冻伤样的皮肤改变。Keep ice from touching the coat directly; use a towel barrier.
• 炎热天气、没有冷藏条件时，尽量把接运安排在当天，不要拖过夜。In hot weather without refrigeration, arrange same-day collection rather than waiting overnight.
• 留出通风，不要密封在闷热的塑料袋里再晒太阳。Avoid a sealed plastic bag left in heat or sunlight.

到底能等多久

How long you can reasonably wait

没有一个对所有家庭都安全的固定小时数，因为它取决于环境温度、体型、死亡原因和是否需要送检。可以记住一个负责任的范围：在凉爽、有冷藏的条件下，一到两天内安排处理通常是从容的；在室温、尤其是夏天，最好在当天到十几小时内接走。

There is no universal safe number of hours because temperature, size, cause of death and testing all matter. A responsible range: with cool storage, arranging care within one to two days is comfortable; at room temperature, especially in summer, same-day collection within hours is better.

与其记一个数字，不如直接问接收方：“以我家现在的温度和条件，最晚什么时候交给你们？”他们每天处理这类情况，给出的具体时间比网上任何通用说法都可靠。

Rather than memorizing a number, ask the receiver: given the temperature and conditions here, what is the latest time I can hand it over? They handle this daily and their answer beats any generic rule.

几个容易出错的地方

Common mistakes to avoid

用冷冻代替冷藏Freezing instead of chilling

需要尸检或希望仪容自然时，冷冻会让组织结冰、解冻后状态变差，也会让接运方难以处理。Freezing harms tissue needed for necropsy and worsens appearance after thawing.

自行长时间留在床上或沙发上Leaving it on bedding for long

情感上能理解，但不降温、不防漏会让床垫和身体都难以收拾，下面务必垫防水层。Use a waterproof layer and cooling to protect both the body and furniture.

往身上或嘴里塞东西Placing objects in the mouth or body

放松的肌肉无法固定物品，强行塞入反而造成损伤，交给专业机构处理。Relaxed muscles cannot hold objects; forcing them causes damage.

在没确认离世前就开始身后安排Planning aftercare before confirming death

若还有一丝不确定，先联系兽医，网页和“没动静”不能代替专业判断。When unsure, contact a veterinarian first; a webpage cannot confirm death.
