Different Resectoscopes Effects to Optic Nerve Sheath Diameter

Not Applicable

Completed

• Conditions: Optic Nerve Sheath Diameter
• Interventions: Procedure: Effect of different resectoscope fluids on optic nerve diameter measured by ultrasound

• Registration Number: NCT04765397
• Lead Sponsor: Bursa Yüksek İhtisas Education and Research Hospital

Brief Summary

In this study, in patients with benign prostatic hypertrophy, monopolar and transurethral prostate using bipolar techniques in resection; serum electrolytes in the perioperative period, osmolarity can occur in hemodynamic parameters the effect of changes on optic nerve diameter by ultrasonography.

Detailed Description

This study is for TURP operation for Benign Prostate Hypertrophy patients. When patient comes to the operating room, routine preparations will be made. Haemodynamic parameters and over-the-eye with Optic nerve diameter will be checked with ultrasound before and 10 minutes after spinal anesthesia. Monopolar for patients according to the preference of the surgical team resectoscope technique or bipolar resectoscope technique will be applied. During the operation Blood pressure, pulse minute the number of irrigation solutions used and the amount of intravenously administered serum, operation time will be saved. Optic nerve sheath diameter after the operation would be checked again. intraoperative and postoperative complications in the waking room (respiratory distress, hypotension, hypertension, bradycardia, tachycardia, vomiting, headache, restlessness, seizure, arrhythmia, vision disorder) will be recorded.

Arm && Interventions

Group	Intervention	Description
Group B	Effect of different resectoscope fluids on optic nerve diameter measured by ultrasound	Patients are in this group with bipolar technique according to the resectoscope technique used by the surgeon.Demographic data of the patients, mean arterial pressure (MAP), pulse minute number (NDS), peripheral oxygen saturation (SpO2), irrigation and intravenous fluid amounts, operation times, serum electrolytes (Na +, K +) and hemoglobin levels were analyzed and recorded.
Group M	Effect of different resectoscope fluids on optic nerve diameter measured by ultrasound	Patients are in this group with monopolar technique according to the resectoscope technique used by the surgeon.Demographic data of the patients, mean arterial pressure (MAP), pulse minute number (NDS), peripheral oxygen saturation (SpO2), irrigation and intravenous fluid amounts, operation times, serum electrolytes (Na +, K +) and hemoglobin levels were analyzed and recorded.

Primary Outcome Measures

Name	Time	Method
optic nerve sheath diameter(mm)	operation time 3 hours	A linear 10-5 MHz ultrasound probe (GE Healthcare Logiqe Series) was held on the upper eyelid over the gel carefully. Part of the optical nerve that enters the orbital globe was monitorized in the 2D mode without exerting much pressure. Diameter of the optic nerve sheath was measured 3 mm behind the optic disk using an electronic caliper after the right contrast was found between the retrobulber echogenic fatty tissue and the vertical hypoechogenic band
