Drop-like, transient blisters of miliaria crystallina may develop with focal intensity of heat within the skin, such as occurs in tropical climates or during febrile episodes. Miliaria crystallina develops due to a transient poral closure of the sweat duct opening, resulting in obstruction of free flow of eccrine sweat and retention in a vesicle below the skin surface. Dual cholinergic and adrenergic sweat gland innervation is influenced by a variety of medications used in intensive care patients. We present two febrile intensive care patients in whom enhanced alpha-adrenergic stimulation of sweat gland myoepithelia may have led to miliaria crystallina.
晶痱的滴状、短暂性水疱可能因皮肤内局部热强度而出现，比如在热带气候或发热期间就会发生这种情况。晶痱是由于汗腺导管开口的短暂性毛孔闭合而形成的，这会导致小汗腺汗液自由流动受阻，并在皮肤表面下方的水疱中潴留。重症监护患者使用的多种药物会影响胆碱能和肾上腺素能汗腺的双重神经支配。我们报告了两名发热的重症监护患者，其中汗腺肌上皮细胞的α-肾上腺素能刺激增强可能导致了晶痱。
