The Effect on Inhibition of Raising Intraocular Pressure during Endotracheal Intubation in Man / 대한마취과학회지

ABSTRACT

After various anesthetic inductions, the effects of tracheal intubation on mean arterial preasure(MAP) and intraocular pressure(IOP) were studied in 88 random patients who did not have any cardiovascular and ocular diseases properatively. IOP and MAP were measured with a Perkins hand held applanation-tonometer and a Cardi- 8- mini syhygmomanometer respectively. The results were as follows 1) Both the MAP and IOP were increased in succinylcholine and pancuronium anesthetic induction groups after endotracheal intubation. 2) Rises in,both the MAP and IOP were inhibited in induced hypotensive anesthetic induction with halothane and trimethaphan. 3) The IOP was inhibited in the propranolol group. These results show the superiority of induced hypotensive anesthetic induction with halothane, trimethaphan and propranolol prior to administration for inhibition of raising intraocular pressure.
