２０例择助手术病人随机分为两组：异丙酚组（ｐ组）．麻醉诱导用异丙酚２ｍｇ／ｋｇ；硫喷妥钠组（Ｔ组）。麻醉诱导用硫喷妥钠５ｍｇ／ｋｇ。观察两组在麻醉诱导和气管插管时不同时间病人眼内压的变化。结果表明，异丙酚和硫喷妥钠均有降低眼内压的作用，但的者比后者的作用更强（Ｐ＜０．０１）。异丙酚能明显抑制气管插管引起的眼内压升高。提示异丙酚可作为眼科手术较理想的麻醉药。
Twenty patients undergoing selective surgery were randomly divided into two groups: propofol group (p group). Induction of anesthesia with propofol 2mg / kg; thiopental group (T group). Induction of anesthesia with thiopental 5mg / kg. The changes of intraocular pressure (IOP) in the two groups were observed at different times during anesthesia induction and tracheal intubation. The results show that both propofol and thiopental sodium have lower intraocular pressure, but the role of the latter than the stronger (P <0.01). Propofol can significantly inhibit tracheal intubation caused by increased intraocular pressure. Prompt propofol can be used as ophthalmic surgery more ideal anesthetic.
