Menstrual cycle effects on optic nerve sheath diameter during laparoscopic gynecologic surgery
This study will try to see if menstrual cycle phase changes the optic nerve sheath size and affects postoperative nausea, vomiting, and thinking in women having elective laparoscopic gynecologic surgery.
-
Head-down position and abdominal gas effects on optic nerve sheath size during robotic prostate removal
This will see if the steep head-down position and abdominal gas used during robot-assisted prostate removal increase the optic nerve sheath diameter in men having prostatectomy.

Identifying predictors for waking up after cardiac arrest
This study is trying to find out which early signs can help doctors predict if patients will wake up successfully after having a cardiac arrest outside the hospital.
