Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients who were between 18-65 years old and who would have elective supratentorial tumour surgery will be included.After positioning the participant for surgery. Surgeons will open a small hole (diameter is under 5 mm) to cranium. for inserting the intracranial pressure measurement (ICP) probe.Probe will be inserted immediately adjacent the tumor.
Patients will be randomly allocated to an anti-edema treatment arm either Mannitol group (Arm I) and Hypertonic Saline Group (Arm II).
In Arm I: 20 % mannitol (with dose of 1gr/kg) will be given to patients as an intravenous infusion in 15 minutes.
In Arm II: 3% NACL (with dose of 5 ml / kg) will be given to patientsas an intravenous infusion in 15 minutes.
Patients were examined during treatment and 30 minutes after anti-edema treatment. Surgery will not commence until 30 minutes after anti-edema treatment. Patients' intracranial preasure, mean arterial preasure and state entropy values will be measured and recorded before treatment and every 1 minute until examination finished. An arterial blood gas will taken before treatment and every 10 minute until examination finished.( totaly 45 minute).

Summary
Brief summary
The present study aimed to compare that anti-edema effects of hypertonic saline and mannitol.
Patients who are between 18-65 years old,who belonge to ASA I- III and who would have elective supratentorial tumour surgery will be included.
Demographic features of the patients, medications, localization of the tumor, maximum diameter of the tumor measured by CT, volume of the tumor and level of midline shift will be recorded. Initial systolic arterial pressure, mean arterial pressure and diastolic arterial pressure will recorde. Patients will monitored for heart rate (HR) using five-channel ECG, noninvasive blood pressure, peripheral oxygen saturation (SpO2), end-tidal CO2 (ETCO2), state entropy (SE) using an entropy module, and train-of-four (TOF) using a neuromuscular transmission module. For anesthesia induction 1 mcg/kg fentanyl, 0.6mg/kg rocuronium bromure will administered and 1% propofol will be used until the SE value will be below 60. After surgery position, Surgeons will open a small hole (diameter is under 5 mm) to cranium. for inserting the intracranial pressure measurement (ICP) probe. Probe will be inserted immediately adjacent the tumor. Patients will seperated into two groups according to anti-edema treatment randomly as Mannitol group (Arm I) and Hypertonic Saline Group (Arm II).
In Arm I: 20 % mannitol (with dose of 1gr/kg) will be given to patients in 15 minutes.
In Arm II: 3% NACL (with ose of 5 ml / kg) will be given to patients in 15 minutes.
Patients were examined during treatment and 30 minutes after anti-edema treatment and surgery not will begin unless examination finished. Patients' intracranial preasure, mean arterial preasure and state entropy values will be measured and recorded before treatment and every 1 minute until examination finished ( totaly 45 minute).
