目前用于临床降低颅脑内压和眼内压的首选药物中,当推静脉注射用高渗尿素和甘露醇注射液。近年来又见口服甘汕降低眼内压治疗青光眼的报道。高渗尿素降低颅压、眼压效果肯定可靠,但有若干副作用和一些禁忌症等之缺点。我们在实际工作中也发现尿素制成溶液后甚不稳定,不能耐热灭菌,重结晶技术操作较繁琐,临床使用也甚感不便。口服甘油降低眼内压临床报道疗效确实。我院除应 Currently used for clinical choice of intracranial pressure and intraocular pressure preferred drugs, when the injection of intravenous hypertonic urea and mannitol injection.

Oral glycerol intraocular pressure to reduce clinical efficacy reported indeed. In addition to our hospital
