Study Description
Brief Summary:
The purpose of this study is to determine which drug makes lower intraocular pressure

Condition or disease Intervention/treatment Phase
Intraocular Pressure Drug: atracurium Drug: cisatracurium Phase 2

Detailed Description:
Increase in intraocular pressure (IOP) following tracheal intubation during general anesthesia can be troublesome. The investigators compared the influence of cisatracurium and atracurium on IOP in patients undergoing general anesthesia.

Arms and Interventions

Arm Intervention/treatment
Patients who underwent general anesthesia received atracurium
Drug: atracurium
atracurium, Drop,0.5 mg/kg, one time, one day
Patients who underwent general anesthesia received cisatracurium
Drug: cisatracurium
cisatracurium, drop,0.15mg/kg,one time, one day

Outcome Measures

Primary Outcome Measures :
  1. intraocular pressure [ Time Frame: at 2 minutes after intubation ]
    determining intraocular pressure in atracurium and cisatracurium groups

Secondary Outcome Measures :
  1. systolic blood pressure [ Time Frame: at 2 minutes after intubation ]
    identification of systolic blood pressure in atracurium and cisatracurium groups
