Comparative analysis of variation in intraocular tension withvecuronium bromide and atracurium besylate: A prospectivestudy

Intraocular pressure is the pressure exerted by the contents of the eye against its containing wall. During general anaesthesia, the intraocular pressure can increase, rendering problems in ophthalmic surgery especially surgery on the eye bulb. Pre-treatment with non-depolarising muscle relaxant prevents fasciculation and so the intraocular pressure does not rise. This is a prospective randomized study of 100 patients divided into two equal groups, where we have compared the effect of vecuronium bromide and atracurium besylate on intraocular pressure. The intraocular pressure was measured before surgery, at the time of intubation and at every 10 minutes interval during surgery. All the data were analysed statistically using unpaired student t test. We concluded that vecuronium bromide has better control over intraocular pressure as compared to atracurium besylate.
