Child reports sudden, worsening pain — rush to the hospital right away; don’t let him wait until after school.
孩子说突然剧痛、而且越来越重，立刻去医院，不要让他忍到放学
No cost at all. Just take a half‑day off work and take your child to the emergency department.
Some medical conditions are time‑critical — the outcome depends on how many hours pass from symptom onset. When a boy suddenly feels severe pain on one side of the scrotum, it may be testicular torsion: the blood vessels feeding the testicle become twisted, cutting off its blood supply. If treated within 6 hours, there’s a 97.2% chance of saving the testicle; after 19–24 hours that chance drops to only 42.5%. This kind of pain won’t wait until after school or until the end of an exam.

Original recommendation and evidence
1. Child reports sudden, worsening pain — rush to the hospital right away; don’t let him wait until after school.
Cost: No cost at all. Just take a half‑day off work and take your child to the emergency department.
In plain terms: Some medical conditions are time‑critical — the outcome depends on how many hours pass from symptom onset. When a boy suddenly feels severe pain on one side of the scrotum, it may be testicular torsion: the blood vessels feeding the testicle become twisted, cutting off its blood supply. If treated within 6 hours, there’s a 97.2% chance of saving the testicle; after 19–24 hours that chance drops to only 42.5%. This kind of pain won’t wait until after school or until the end of an exam.
Benefit: Researchers compiled data from 30 case series and 2,116 patients with testicular torsion. For 1,283 of those cases the outcome was tracked in 6‑hour intervals. From the start of pain: 97.2% of testicles were saved at 0–6 hours, 79.3% at 7–12 hours, 61.3% at 13–18 hours, 42.5% at 19–24 hours, 24.4% at 25–48 hours, and just 7.4% after 48 hours. Looking at broader windows, 90.4% of testicles remain intact if treatment occurs within 12 hours; 54.0% are still salvageable at 13–24 hours, and 18.1% after 24 hours. The authors conclude that the window for preserving a testicle can be longer than the commonly cited 6–8 hours. Therefore, even if pain has been present for a while, prompt medical care is still essential — don’t assume it’s “too late” to get help.

Notes: Tell your son in advance: if he suddenly feels severe pain, he should speak up right away — no need to feel embarrassed. Testicular torsion is most common in adolescent boys; many hesitate to ask for help because they’re shy. Other conditions that also worsen hour by hour include acute appendicitis (which can perforate if delayed), diabetic ketoacidosis, and meningitis. For these, the exact time‑based impact on outcomes isn’t detailed in this section. Their common warning sign is sudden onset and steadily worsening pain unlike anything experienced before. How to recognize emergencies and call for transport are covered in Section 13.

1. 孩子说突然剧痛、而且越来越重，立刻去医院，不要让他忍到放学
成本: 不花钱。请半天假，带孩子去挂急诊。
说人话: 有些病是按小时算的。男孩突然一侧阴囊剧痛，是睾丸扭转，也就是睾丸连着的那根血管拧住了，血供断了。6 小时内处理，睾丸保住的比例 97.2%。拖到 19 至 24 小时，只剩 42.5%。这种痛等不到放学，也等不到考完。
收益: 按规矩把 30 组病例报告、2116 例睾丸扭转患者找齐，合起来看。其中 1283 例是按 6 小时一档统计的。从开始痛算起，0 至 6 小时睾丸保住的比例 97.2%。7 至 12 小时 79.3%。13 至 18 小时 61.3%。19 至 24 小时 42.5%。25 至 48 小时 24.4%。超过 48 小时 7.4%。合并成大段看，12 小时内 90.4%，13 至 24 小时 54.0%，超过 24 小时 18.1%。作者的结论是，能保住的时间可以比通常说的 6 至 8 小时更长。所以就算已经痛了很久，也还是要去处理，不要因为「反正晚了」就不去

备注: 提前跟男孩说一句：下面要是突然剧痛，马上讲，不用不好意思。睾丸扭转多发于青春期男孩，不少人因为难以启齿就硬忍。同样按小时算的还有急性阑尾炎（拖久了会穿孔）、糖尿病酮症酸中毒、脑膜炎。这几种本节没有逐条核实过「拖几小时坏多少」。它们共同的信号是：突然发作，一直加重，和以往任何一次都不一样。急症怎么认、怎么叫车见第 13 节。
