The study aimed to compare ultrasound guided pericapsular nerve group (PENG) block versus interscalene brachial plexus block for postoperative analgesia following shoulder arthroscopy.
Shoulder arthroscopy can effectively treat a number of injuries and diseases of the shoulder on an ambulatory basis. Although shoulder arthroscopy is considered minimally invasive, it is related to severe postoperative pain. The use of arthroscopy is popular because it decreases pain, shortens hospital stay, and improves patient satisfaction. However, immediate postoperative pain remains to be a problem in more than 40% of patients. Regional anesthesia, especially peripheral nerve blocks have various advantages like decreased need for postoperative analgesics, decreased incidence of nausea and vomiting, shortened recovery time and hospital stay, Early ambulation and discharge. Interscalene brachial plexus (ISB) block is considered the gold standard technique for pain management in shoulder surgery as it provides the most reliable analgesia. However, it has the potential for many complications. The most common of these complications is phrenic nerve palsy, which is reversible but may result in significant respiratory distress especially in patients with compromised respiratory function. Other less common yet serious complications include Horner's syndrome, recurrent laryngeal nerve block that may result in hoarseness of voice, vascular puncture, brachial plexus neuropathy, and unintended injection of local anesthetic into the subarachnoid space, epidural space, or vertebral artery. Pericapsular nerve group (PENG) block is a new block that provides a pericapsular distribution with local anesthetic infiltration around the glenohumeral joint and provides analgesia by reaching the sensory nerve branches of the glenohumeral joint.

Patients will receive ultrasound guided interscalene brachial plexus block after induction of general anesthesia. Scanning with SonoSite M-Turbo C ® Ultrasound device with HFL - 38 X Linear probe (Japan) with high frequency (6 -13 MHz) will be started just below the level of the cricoid cartilage medial to the sternocleidomastoid muscle. the transducer will be moved slightly laterally across the neck to identify the scalene muscles and the brachial plexus that is present between the anterior and middle scalene muscles at the level of the sixth cervical vertebra deep to the sternocleidomastoid muscle. The needle will be then inserted in-plane toward the brachial plexus, in a lateral-to-medial direction. After negative aspiration and assurance that high resistance to injection is absent, 0.25% bupivacaine hydrochloride will be injected in a 5-ml increment below the lower root, between the 3 roots, and above the upper root.(Total amount is 15 ml of 0.25% bupivacaine hydrochloride).
Patients will receive ultrasound guided Pericapsular nerve group (PENG) block after induction of general anesthesia. Using SonoSite M-Turbo C ® Ultrasound device with HFL - 38 X Linear probe (Japan) with high frequency (6 -13 MHz) ,A linear ultrasound probe will be placed longitudinally between the coracoid and the humeral head. After defining the humeral head, the tendon of the subscapular muscle and the deltoid muscle over it, a 50-mm needle will be inserted using the ''in plane'' technique. When the needle pass through the deltoid muscle and touched the subscapularis tendon, a bone-like hard tissue will be felt and the needle can't be advanced further. The needle tip will be placed between the deltoid muscle and subscapularis tendon, after a careful aspiration, 15 ml of 0.25% bupivacaine hydrochloride will be injected.

RECRUITINGFirst time for requiring analgesia
First time for requiring analgesia. It will be defined as the time from recovery until VAS score greater than 3.
Time frame: 24 hours postoperatively
Total amount of pethidine consumption in the first 24 hours
If the patient complained of pain, intravenous pethidine sulfate will be (50mg/dose) to be repeated on demand (VAS is \> 3) provided that the total 24-hour dosage not to exceed 50 mg every 6 hours.
Time frame: 24 hours postoperatively
The degree of pain
The degree of pain will be measured using visual analogue scale (VAS)ranging from 0 to 10, where 0 no pain and 10 maximum pain. It will be evaluated on arrival to PACU (T0) then at 2, 4, 6, 12, and 24 h postoperatively.
Time frame: 24 hours postoperatively
Complications
Any complications during and after the performance of the block - for example, pneumothorax, Horner's syndrome, hoarseness of voice, difficulty in breathing, weakness, and paresthesia in the arm will be recorded.
Time frame: 24 hours postoperatively
