Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Is PENG block effective in prolonging the duration of postoperative analgesia when compared to patients undergoing spinal anesthesia only?
Research Hypothesis:
PENG block is effective in prolonging the duration of postoperative analgesia and reducing postoperative pain.
Aim:
To improve the outcome of hip joint surgeries by decreasing the postoperative pain and early mobilization by performing PENG block to patients undergoing hip joint surgeries.
Method of randomization:
This clinical trial will be randomized through computer software that generates random number table and patients will be allocated randomly to one of the two groups.
Sample size:
The sample size was determined by using the following equation:(Charan J et al. 2013) N =(2 δ\^(2 ) 〖(Z\_α+ Z\_β)〗\^2)/D\^2 δ=Standard deviation of the outcome = 6.7 (Pascarella et al., 2021). Z\_α= The value for a type I error of 5% = 1.96 Z\_β=The value for a type II error of 20% = 0.84 D\^2= The effect size = 36 (Pascarella et al., 2021).
By calculation:
N = 19 per group. So, the total sample size is 38.
Procedures:
After getting the informed consent from the patient, the patient will be allocated into one of the study groups according to randomization.
ASA standard monitors will be attached to the patient, a wide pore cannula (18G) will be inserted then a premedication with 50 -100 mcg of fentanyl and 1-2 mg midazolam intravenously will be given.
PENG group: PENG block will done under complete aseptic condition with 20 ml 0.25% bupivacaine diluted with normal saline Control group: no block will be done. Both groups will be anesthetized using spinal anesthesia with Bupivacaine
Study Variables:
Independent variables: age, sex, weight, height, body mass index (BMI), elective or emergency surgery, duration of surgery, American Society of Anesthesiologists physical status classification (ASA score), occupation, fracture site, type of trauma, timing (operating room entry- PENG block time- start of spinal anesthesia- start of surgery- end of surgery ).
Dependent variables: Postoperative pain, adverse events, and postoperative motor assessment, hemodynamics, the first request of analgesia \& total analgesia required, adverse events such as nausea vomiting \& sedation, pain scores at preparation room, after PENG block, during sitting for spinal anesthesia, at end of the surgery, postoperative intervals(rest \& movement).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control Group
Patients in this group will be operated under spinal anesthesia
No interventions assigned to this group
PENG Group
Patients in this group will undergo PENG block guided by ultrasound then spinal anesthesia will performed
PENG Block
With the patient in the supine position, the ultrasound probe is placed on a transverse plane over the anterior superior iliac spine (ASIS). Once the ASIS is identified, the transducer is aligned with the pubic ramus and rotated at approximately 45 degrees, parallel to the inguinal crease. The transducer then slides medially along this axis until the anterior inferior iliac spine (AIIS), iliopubic eminence (IPE), and the psoas tendon is clearly identified, serving as anatomic landmarks. Sliding the probe distally or gently tilting the caudal will expose the head of the femur. Returning to the initial starting position, a standard 22 gauge spinal needle is inserted in-plane, from lateral to medial, in the plane between the psoas tendon and the pubic ramus. 20 ml 0.25% bupivacaine diluted with preservative free normal saline then deposited in this plane, lifting the psoas tendon. Care should be taken to avoid puncturing the psoas tendon.
