Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In this study, the investigators will monitor the changes observed in intraocular pressure caused during an operation in two different artificial respiration methods:
1. Intermittent positive pressure ventilation (IPPV)
2. High frequency jet ventilation (HFJV)
Study recruited 50 patients aged 18 - 40, candidates to elective orthopedic surgery in the limbs. These patients do not suffer from general diseases that restrict their daily functioning.
The selection of the type of surgery was done to prevent the involvement of any other factor, except the respiration method, determination of intraocular pressure.
Exclusion Criteria:
* Patients who are unable to provide an Informed Consent
* Patients suffering from any eye disease
* Patients with corneal thickness less than 450 microns or more than 600 microns
* Smokers
* Patients with pulmonary disease restrictive or obstructive
* Patients using bronchodilator
All patients operated under general anesthesia using total intravenous anesthesia )TIVA) method.
All patients will be resuscitating half of the time of surgery using IPPV, and in the second half of surgery using HFJV.
During the surgery the IOP will be measured by an ophthalmologist who is unaware of the respiration method.
Correction will be made to the intraocular pressure values, depending on the thickness of the cornea.
The results of the measurements will be collected and the clinical significance will be reviewed by acceptable statistical methods.
