Summary

During surgery, researchers use different methods in respiratory equipment. In the study researchers examine the effects of these methods on intraocular pressure changes by looking at the intraocular nerve diameter. Then look at the effects of these effects on patients conscious functions by asking some questions.

Detailed description

According to the mechanical ventilator application to be applied to the patients; Group P (n: 30) pressure controlled ventilation (PCV), Group V (n: 30) volume controlled ventilation (VCV) are randomly assigned to two groups. General anesthesia will be applied to all patients. Mechanical ventilation settings will be able to 8ml / kg TV (tidal volume). Demographic data (age, gender, weight, height) of patients, duration of surgery and peroperative complications will be recorded choosen time intervals.T0: awake, T1: 5th min after induction, T2: Gas insufflation start in supine position, T3: Maximum gas pressure is reached in reverse trendelenburg position, T4:Before extubation. SAB, DAB, OAB, KAH, SpO2, Ppeek, PEEP, EtCO2, optic nerve diameter will be recorded at same times. Cognitive function test will be performed at postoperative 24th hour for comparing the first awaken routin MMDT (Mini Mental Status Detection) scale. The same test will be repeated for patients who are called for routine general surgery outpatient control 3 months after surgery.
