Summary

The aim of the study to evaluate the efficacy of the infraspinatus-teres minor (ITM) block in improving pre-emptive analgesia, reducing opioid consumption, and enhancing the overall analgesic effect in patients undergoing shoulder surgeries.

Detailed description

To compare between infraspinatus-teres minor versus control group (GA): 1. To measure analgesic parameters including: the total amount of rescue analgesic consumption (morphine) in the first 24 hours post-operatively in each group, duration of analgesia, and total amount of intraoperative fentanyl consumption and 2. To assess pain score by using numerical rate scale (NRS) at rest (static) and during passive or active movement of shoulder joint (dynamic). 3. To assess discharge time from post anesthesia care unit (PACU). 4. To assess side effects of systemic opioids (constipation, itching, dizziness, nausea and vomiting) and complications of infraspinatus-tere minor block. 5. Patients' satisfaction: The patients will be asked to rate the overall degree of satisfaction of the analgesia by using a 5-points Likert-like verbal scale (1 = very dissatisfied analgesia, 2 = dissatisfied analgesia, and 3 = neutral, 4=satisfied analgesia, and 5=very satisfied analgesia).

Conditions

• Preemptive Analgesia

Interventions

Type	Name	Description
PROCEDURE	Infraspinatus teres minor block group	Patients in this group will receive a unilateral ultrasound-guided Infraspinatus-teres minor (ITM) block with injection of local anesthetics (20 mL of bupivacaine 0.25% (50 mg), 50 mcg dexmedetomidine (0.5 ml) and 8 mg dexamethasone (2 ml)) before induction of general anesthesia
PROCEDURE	Control group	Patients in this group will receive general anesthesia
