Shoulder Anterior Capsule Block Combined With Suprascapular Nerve Block Versus Interscalene Block as a Sole Anesthetic Technique for Shoulder Arthroscopy

Evaluation of shoulder anterior capsule nerve block combined with suprascapular nerve block as an adequate sole anesthetic technique in shoulder arthroscopic surgeries without significant affection of motor power and pulmonary function.

Detaljeret beskrivelse

Ultrasonographic peripheral nerve block has been a popular technique not only for pain management but also for surgical anesthesia especially in patients with comorbidities, avoiding complications associated with general anesthesia (airway-difficulties, hemodynamic instability, etc.) and ensuring excellent pain control, reducing peri-operative consumption of opioids and their side effects, and improving patient satisfaction.

Interscalene block (ISB) is the gold stander anesthetic technique for shoulder surgeries but hemi-diaphragmatic paralysis still problematic. The SHAC is the combination of two different blocks. The first block is the inter fascial space between the deep layer of the deltoid fascia and the superficial layer of the subscapularis fascia, anterior to the subscapularis myotendinous junction. This inter fascial space, we can reach both the axillary nerve and the subscapular nerves, the lateral pectoral nerve, and the musculocutaneous nerve results in achieving adequate anesthesia and analgesia without phrenic nerve affection.

The present study will be conducted to compare of SHAC block combined with suprascapular nerve block and Interscalene block as an anesthetic option in shoulder arthroscopic surgery may allow adequate postoperative analgesia and decrease the overall opioid usage and enhanced patient recovery

Tidsramme
Safety of SHAC block by monitoring of complications eg. local anesthetic toxicity , hemodynamics instability, phrenic nerve affection, pneumothorax.
Tidsramme: From start of surgery and for the 1st 24 hours.
Monitoring of complications like local anesthetic toxicity ( restlessness, irritability, confusion, convulsions and arrhythmias) hemodynamics instability, phrenic nerve affection ( diaphragmatic paralysis) , pneumothorax ( decrease in oxygen saturation monitoring, tachypnea, diminished air entry on affected side by auscultation).
From start of surgery and for the 1st 24 hours.
Patient satisfaction with the anesthesia and analgesia during and after surgery
Tidsramme: From start of surgery and for the 1st 24 hours postoperatively.
Patient satisfaction was evaluated by using satisfaction score and patients were graded on a 5-point scale: 1 = very dissatisfied, 2 = dissatisfied, 3 = neutral, 4 = satisfied, 5 = very satisfied, and assessed at 24 h post-operation
From start of surgery and for the 1st 24 hours postoperatively.
