Study type
Interventional
Description of intervention(s) / exposure
Before the operation,patient’s previous history of spinal anesthesia, current headache and low back pain data will be recorded . Patients will be placed in the sitting position according to routine spinal anesthesia protocol.
In this initiative; 25G Quincke tipped spinal needle used in the hospital Patients were grouped according to the cutting direction of the dura mater of the spinal needle ; sagittal (parallel to duramater fibers) and transverse (perpendicular to duramater fibers). Randomization was performed by a computer-generated scheme (computerized sequence generation). In both groups, 2 ml of .0.5% hyperbaric bupivacaine will be given intrathecally after the free flow of cerebrospinal fluid is observed. Patients's hemodynamic data (noninvasive systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, pulse, oxygen saturation) will be recorded before the operation and after the spinal anesthesia at 1st, 3rd, 5th, 7th, 10th,15th, 20th, 25th, 30th, 40th, 50th, 60th minute. After the intervention, the patients will be placed in the supine position and support will be placed on the back and hip area to be left lateral for 15 degrees. Sensory block will be evaluated with pinprick test and operation will start at T4-T6 level.
10 ml / kg of ringer lactate solution will be given to the patients before the operation. In case of a 20% or more decrease in arterial pressure compared to basal measurments during operation, 5-10 mg ephedrine intravenously will be given. In addition, the number of attempts for successful intervention will be recorded. Patients will be phoned by the investigators in terms of headache and other possible complications one week after the operation. Patients with headache will be evaluated according to VAS score.
