Brief Summary

This study aimed to evaluate the analgesic efficacy of preoperative ultrasound-guided peri-capsular nerve group block (PENG) on postoperative analgesia after shoulder arthroscopic surgery.

Detailed Description

Postoperative pain control after shoulder surgery is challenging, and poor pain management is invariably reflected in poor outcomes, with longer hospitalization and recovery time. The difficulty in reducing pain due to the complexity of shoulder innervation leads to conducting studies to explore selective axillary nerve blocks with a posterior approach or from the axillae.

The peri-capsular nerve group (PENG) block is a regional anesthetic technique. It can be effectively and safely applied under ultrasound guidance in shoulder surgery cases for postoperative analgesia. It targets only the sensory branches and not the posterior mechanoreceptors; there is a potential motor-sparing effect which is desirable for better physical therapy, and earlier discharge.

Arm && Interventions

Group	Intervention	Description
Control Group	Saline	Patients received sham PENG block (just 1mL saline).
PeriCapsular Nerve Group Block (PENG) Group	Bupivacaine + Dexamethasone	Patients received real PENG block (15 mL of bupivacaine 0.25% +0.2mg/mL dexamethasone).

Primary Outcome Measures

Name	Time	Method
Time to the first request of rescue analgesia	24 hours postoperatively	Time to the first request of rescue analgesia was recorded from the end of the surgery till first dose of morphine administrated.

Secondary Outcome Measures

Name	Time	Method
Degree of pain	24 hours postoperatively	The degree of pain was assessed using the Numerical Rating Scale (NRS) Pain score (metric score from 0 to 10 where 0 = no pain and 10 = maximal pain). NRS was recorded at PACU and 2, 4, 6, 8, 12, 16, 20, and 24 h postoperative.
Total morphine consumption	24 hours postoperatively	If patient numeric rating score was more than 3, patients received 3 mg morphine slowly intravenously. Morphine injection was repeated whenever required.
