ABSTRACT
OBJECTIVE: Aim: To determine whether the Trendelenburg position during laparoscopic urological surgery changed the ONSD and whether changes correlated with postoperative complications.
PATIENTS AND METHODS: Materials and Methods: In this prospective study, we measured ONSD before patients were placed in the Trendelenburg position. Then the Trendelenburg position was established by tilting the operating table to 20-25 degrees. After surgery, the patients were placed in a horizontal position, and the second measurement of ONSD was obtained.
RESULTS: Results: The study included 69 patients. The average preoperative ONSD in the right eye was 5.8±0.7 mm and 5.8±0.8 mm in the left eye. The average postoperative ONSD in the right eye was 6.6±0.8 mm and 6.6±0.7 mm in the left eye. The differences between postoperative and preoperative values in the right and left eyes were statistically significant (p<0.000001). ONSD increases above the norm did not correlate with the incidence of postoperative nausea (p=0.94), delirium (p=0.81), or the time to patient awakening (p=0.29).
CONCLUSION: Conclusions: ONSD increased in patients who underwent surgical procedures performed in the Trendelenburg position, but the increase did not correlate with postoperative complications.
