Postoperative localized alopecia has been reported most commonly after certain gynecologic and open heart surgery procedures, the likelihood of hair loss and the chance of permanence correlating with the length of the anesthesia and the intubation. Some cases of pressure-induced alopecia have been described after prolonged coma from other causes. Coma blisters have been reported after drug overdoses, but clinically similar blisters (not tested by biopsy) have been seen in other cases of coma. We present three cases of postoperative (pressure) alopecia and propose that both coma blisters and postoperative alopecia arise from the same phenomenon--probably pressure-induced ischemia.
术后局部脱发最常见于某些妇科手术和心脏直视手术之后，脱发的可能性和永久性与麻醉时间及插管时间相关。在因其他原因导致的长时间昏迷后，也有一些压力性脱发的病例被描述。药物过量后曾有昏迷水疱的报道，但在其他昏迷病例中也可见到临床症状相似的水疱（未进行活检）。我们报告了3例术后（压力性）脱发病例，并提出昏迷水疱和术后脱发源于同一现象——可能是压力性缺血。
