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.

Entropy
Entropy monitoring involves using electroencephalography-a strip of electrodes applied to the forehead-to assess the depth of general anesthesia in surgical patients. The goal of entropy monitoring is to ensure that patients are given appropriate levels of anesthesia so that recovery is faster. Entropy monitoring provides quantitative measurement of depth of anaesthesia. The Response Entropy scale ranges from 0 (no brain activity) to 100 (fully awake) and the State Entropy scale ranges from 0 (no brain activity) to 91 (fully awake). The clinically relevant target range for entropy values is 40-60.
Time frame: intraoperative 2 hours
SPI
The surgical pleth index (SPI) is a dimensionless score which is based on the photoplethysmographic analysis of the pulse wave and the heart beat interval. SPI scores monitored during surgery may reflect a patient's autonomic response to certain nociceptive stimuli. The values of the SPI range from 0 to 100. During general anaesthesia, maintaining a value between 20 and 50 is generally recommended
