Hip fractures are morbid conditions, especially in elderly patients, and their treatment is usually surgical. Pericapsular nerve group block is a newly defined block and targets the hip capsule. The aim of this study is to investigate and compare the perioperative analgesic efficacy of PENG blocks applied in two different volumes in patients undergoing hip fracture surgery under spinal anesthesia.
Hip fractures are morbid conditions, especially in elderly patients, and their treatment is usually surgical. Pericapsular nerve group block is a newly defined block and targets the hip capsule. The aim of this study is to investigate and compare the perioperative analgesic efficacy of PENG blocks applied in two different volumes in patients undergoing hip fracture surgery under spinal anesthesia. 60 ASA I-III patients between 35-90 years of age who will be operated for femoral head/neck fractures will be included in the study. US-guided block procedure will be applied 30 minutes before the start of surgery. The patients will be divided into two groups, Group I, PENG block 20ml bupivacaine (n:30) and Group II, PENG block 30ml bupivacaine (n:30) using the closed envelope method in the operating room. Randomization will be performed by one of the researchers for each patient. Randomization information of patients will be used for all follow-up and data collection. The anesthetist applying the block will not take any part in collecting the data or performing the analysis. Numerical rating scale (NRS) will be used to evaluate pain. Patients will be given spinal anesthesia 30 minutes after PENG block. The primary outcome measure was determined as pain during positioning. NRS scores will be recorded after entering the operating room before, immediately before, during, and immediately after any analgesic intervention. Secondary outcome measures will be determined as the time required for LA performance (measured from the start of the position maneuvers to removal of the spinal needle), the quality of the patient position for LA performance ("unsatisfactory", "satisfactory", "good", "very good" to define SA). Questionnary 15 test will be applied to the patients 24 hours after the operation to measure patient satisfaction and to measure patient satisfaction.

Pain scores on the Numeric Rating Scale (NRS)
Changes in Numeric Rating Scale (NRS) at rest and on movement will be recorded at intervals. NRS is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").
Time frame: 30 minutes after intervention (PENG block) ]
Duration of spinal anesthesia performance
It will be measured in "minutes", from the start of positioning maneuvers to the spinal needle removal
Time frame: up to ten minutes
Quality of patient's position
The position will be characterized as "unsatisfactory", "satisfactory", "good" or "very good"
Time frame: up to ten minutes
analgesic consumption
In the postoperative period, patients will be given opioids according to their pain density with a patient-controlled device, and the daily Morphine consumption in Patient Controlled Analgesia device will be collected and compared between groups.
Time frame: 24 hours
Quality of recovery 15 scale
Postoperative Quality of Recovery 15 in Turkish scale
Time frame: 24 hours after surgery
Quadriceps weakness
Quadriceps strength will be graded according to a 3-point scale: normal strength = 0 point (extension against resistance); paresis = 1 point (extension against gravity but not against resistance); and paralysis = 2 points (no extension).
