类型是短暂的？

Pruritus due to the administration of epidural opioid. The cause of this side effect is largely unknown, but possibly related to central activation of opioid mu-receptors. Usually, this type of pruritus is transient and thus requires no intervention; if necessary it can be treated with opioid antagonists (naloxone), partial agonists–antagonists (nalbuphine), or antihistamines (diphenhydramine).

由硬膜外给予阿片类药物引起的瘙痒，发生这种不良反应的原因尚不清楚，但可能与阿片µ受体的中枢激活有关。这种瘙痒的类型通常是短暂的，因此不需要干预；如有必要，可以使用阿片受体拮抗剂（纳洛酮）、部分激动-拮抗剂（纳布啡）或者抗组胺药（苯海拉明）来治疗。
