About this study

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.

Treatment and study plan

Effect of different resectoscope fluids on optic nerve diameter measured by ultrasound

Procedure

During the operation Blood pressure, pulse minute the number of irrigation solutions used, and intravenous serum amounts, operation time will be saved. If there is an abnormal parameters or increased optic nerve sheath surgical team will be informed.

Primary outcomes

  1. optic nerve sheath diameter(mm)

    Time frame: 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
