Femoral fracture surgery is frequently performed especially in geriatric population. Compared to general anaesthesia, regional anaesthesia is preferred to general anaesthesia in the geriatric patient population due to lower postoperative pulmonary complications, reduced frequency of delirium and analgesic requirement, intraoperative haemodynamic stability, early postoperative mobilisation and early discharge. Central and peripheral regional anaesthesia methods have advantages and disadvantages. This situation causes difficulties in the choice of anaesthesia method. Central regional anaesthesia techniques have more haemodynamic effects and higher frequency of complications compared to peripheral methods. The disadvantages of peripheral methods are that they require ultrasound, block needle, nerve stimulator and require knowledgeable and skilled practitioners. Since there is no study showing the comparison of peripheral nerve blocks and hypobaric spinal anaesthesia with objective nociception values and there are difficulties in the choice of anaesthesia method in this regard, a study was deemed necessary.
