酸性化学伤过去强调用SD来中和。我们发现在受伤后1小时内,结膜囊内的PH值已恢复正常,这时化学伤的表现主要是局部组织的坏死病,其治疗原则和硷性化学伤的PH值恢复正常后的治疗相同,主要是促进胶原合成、加速组织修复和防止角膜溃疡的发生。维生素C在胶原合成中起很大作用,早期应用它,可能防止角膜溃疡的发生。
Acid chemical injury in the past stressed the use of SD to neutralize. We found that within 1 hour after injury, the conjunctival sac PH value has returned to normal, then the performance of chemical injuries is mainly localized necrosis, the treatment of alkaline chemical injury and the PH value of the normal treatment after the same , Mainly to promote collagen synthesis, accelerate tissue repair and prevent the occurrence of corneal ulcer. Vitamin C plays a large role in the synthesis of collagen, early application of it, may prevent the occurrence of corneal ulcers.
