Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
which block has more analgesic efficacy. which block has more motor-sparing analgesia.
Researchers will compare optimal motor-sparing analgesia between PENG block and PAI after hemiarthroplasty.
Participants will be divided in two groups :
group receive PENG block and other group receive PAI

Detailed Description

PARTICIPANTS AND METHODS:
After approval of the local institutional ethics committee and local institutional review board. Patients who are scheduled for elective hemiarthroplasty and fulfilling the inclusion criteria in Fayoum university hospital starting from October 2024 will be enrolled in this randomized controlled study until fulfilling sample size. A detailed informed consent will be signed by the eligible participants before recruitment.
Inclusion criteria The eligibility criteria included ages from 50 to 90 years, American Society of Anesthesiologists (ASA) physical status I to III, and undergoing bipolar hemiarthroplasty in Fayoum university hospital.
Exclusion criteria Patient refusal, contraindication to spinal anesthesia , clinically significant coagulopathy, infection at the injection site, allergy to local anesthetics, body mass index\>35 kg m2 , diabetic or other neuropathies, patients receiving opioids for chronic analgesic therapy
. ANESTHETIC TECHNIQUE Perioperative anesthesia management will be according to our hospital routine protocol. An intravenous cannula will be inserted in the hand and standard monitoring (noninvasive blood pressure, electrocardiography, and pulse oximetry) will be applied . In all patients, spinal anesthesia will be performed in the sitting position. The midline and level of the L3-4 and L4-5 intervertebral spaces will be identified, and spinal anesthesia will be administered using 10 mg of isobaric bupivacaine (2mL of bupivacaine 0.5%) injected using 25-gauge Quincke needle. Patients will be immediately placed in the supine position. Spinal anesthesia will be considered successful when a bilateral block to T12, as assessed by loss of cold (cold ice) and pain (a 23-gauge needle) sensations, will be established 10 minutes after the intrathecal injection., the bipolar hemiarthroplasty will be performed in all patients in nondependent lateral position.
Randomization and blinding Using a computer-generated sequence of random numbers and a sealed, opaque envelope technique, patients will be randomly allocated to receive PENG block or PAI . The randomization list and opaque envelopes will be created by an assistant who will not be involved in patient care.
Performance of PENG blocks and PAI PENG BLOCK will be performed in the operating room, after skin closure, .Patients will be placed in the supine position. The ultra sound transducer will be placed in a transverse orientation, medial and caudal to the anterosuperior iliac spine in order to identify the anteroinferior iliac spine, the iliopubic eminence and the psoas tendon. Using an in-plane technique and a lateral-to-medial direction, the block needle will be advanced until its tip will be positioned on the periosteum dorsal to the psoas tendon. The LA (20mL of bupivacaine 0.5%) will be injected following negative aspiration.. The accurate position of the needle was confirmed by hydro dissection and spread under the illo-psoas muscle .
PIA BLOCK For subjects randomized to PAI , LA infiltration will be carried out using a total dose of 150mg of bupivacaine and a total volume of 60mL. The admixture (consisting of 60mL of bupivacaine 0.25% ) will be loaded into two 30mL syringes at the beginning of surgery. After insertion of the acetabular component (and before insertion of the femoral stem), the surgeon will infiltrate the deep tissues ( anterior and posterior capsules, gluteus minims and Medius muscles, supraacetabular region, area around the anterior inferior iliac spine, and quadratus fumoirs muscle all the while avoiding the deep hip external rotator muscle group in order to prevent sciatic nerve block) with the first 30mL syringe. Before wound closure, the gluteus maximus muscle, iliotibial band, subcutaneous tissues, and skin will be infiltrated with the second 30mL syringe
Statistical analysis and sample size estimation Before conducting the study, G\*Power 3.1.9.6 will be utilized to establish the appropriate sample size for equal distribution among the two groups based on data from the study by Bravo et al. who recorded median and range between the same two groups for numeric rating scale at 12 hours which is our primary outcome. We convert and calculate these numbers to mean from Luo et al. (2018) and standard deviation from Wan et al. (2014) and found a mean difference of 1.75 and standard deviation of 2.45 and 1.97 for the two study groups creating effect size of 0.78. Depending on a significance level (α) of 0.05, a power (1 - β) of 0.80, allocation ratio 1:1 and two-tailed, a sample size of 27 patients is required for each group. Due to the possibility of dropout rate and exclusion of some objects, the study will be planned to include 60 patients (30 patients in each group).
Statistical analysis will be conducted using IBM SPSS Statistics 22 (IBM Corp., Armonk, NY, USA). The normal distribution of data will be assessed by the Kolmogorov-Smirnov and Shapiro-Wilk tests. Mean and standard deviation will be used as descriptive statistics for normally distributed numerical variables, while median and interquartile range (25th to 75th percentiles) will be used as descriptive statistics for non-normally distributed numerical variables. In addition, Chi-square test will be employed to test the significance between categorical variables. Independent t test will be employed for numerical data that exhibited normal distribution, whereas the Mann Whitney test will be used for numerical data that did not adhere to normal distribution. A significance level of p \< 0.05 will be deemed to be statistically significant
