Further study details as provided by Isfahan University of Medical Sciences:

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

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

Enrollment: 90
Study Start Date: July 2009
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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

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.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

ASA class of I or II baseline IOP of lower than 20 mmHg stable hemodynamics no history of ophthalmic diseases not using drugs affecting IOP (e.g. anticholinergics, sympathomimetics) no contraindication for atracurium or cisatracurium administration.

Exclusion Criteria:

difficulty in mask ventilation or in tracheal intubation end expiratory CO2 of below 35 mmHg or over 45 mmHg O2 saturation of below 90%
