The Effect of Percutaneous Dilatational Tracheostomy on Intracranial Pressure
Percutaneous dilatational tracheostomy (PDT) is a common bedside alternative to surgical tracheostomy in intensive care unit patients. Intracranial pressure measurement is a vital parameter that should be monitored when performing any procedure including PDT in these patients. During PDT, changes in intracranial pressure may occur depending on the position applied, hypercarbia and hypertension that may develop during the procedure. However, the effect of PDT procedure on intracranial pressure is controversial. It is imperative to ascertain the impact of PDT on intracranial pressure, along with the factors that influence its fluctuations during the procedure. This is of particular significance in order to avert the occurrence of deleterious conditions that may be engendered by elevated intracranial pressure. The aim of current study was to evaluate the effect of PDT procedure on intracranial pressure.

Effect of Spinal Needle Type on Optic Nerve Sheath Diameter
The optic nerve sheath is a continuation of the dura mater, extending along the subarachnoid space surrounding the optic nerve. Consequently, changes in intracranial pressure cause an augmentation or contraction in the diameter of the optic nerve sheath, which is coreleted with intracranial pressure. Participants undergoing lower extremity operations (ankle, distal tibia and fibula surgeries) using a tourniquet under spinal anesthesia will be investigated. Spinal anesthesia will be performed with a 25 G Whitacre, 25 G Quincke, or 27 G Quincke needle, depending on the study group. Optic nerve sheath diameter (ONSD) measurements will be performed before spinal anesthesia; and 5 minutes, 15 minutes,,24 hours after spinal block, respectively.The 4th measurement will be performed after tourniquet is opened. Measurements will be done with 15 MHz linear ultrasound (US) probe in B mode, 3 mm behind the posterior globe in the transverse plane from both eyes, on upper eyelid. Values will be recorded numerically. The impact of spinal anesthesia administered using various needle designs (Quincke and Whitacre) and sizes (25G-27G) on intracranial pressure will be investigated.
