The Effectiveness of Different Techniques of Interscalene Brachial Plexus Block With General Anesthesia for Shoulder Arthroscopy

The Effectiveness of Different Techniques of Interscalene Brachial Plexus Block With General Anesthesia for Shoulder Arthroscopy

There are different techniques of interscalene brachial plexus block, we aimed to evaluate the effectiveness of 3 of them as analgesia during shoulder arthroscopy surgery under general anesthesia.

Prospective randomized controlled study

There were 4 groups included in our study:

Group N: nerve stimulator guided interscalene brachial plexus block was done Group U: ultrasound guided interscalene brachial plexus block was done Group NU: dual guidance (using both nerve stimulator and ultrasound) Group C: control group We assessed in each group: heart rate, noninvasive blood pressure, time needed for block, onset of sensory and motor power loss and their offset, and finally patient satisfaction.

Inclusion Criteria:

• Age: 18-65 years old.
• Sex: Both sexes.
• ASA I & II.

Exclusion Criteria:

• - Patient refusal.
• Bleeding disorders.
• Damage or disease of the brachial plexus.
• ASA more than II.
• Pre-existing peripheral neuropathy.
• Patients with neuromuscular diseases.
• Patients with known hypersensitivity to drugs of the study.
• Patients with local skin infection at the site of injection.
• Psychiatric diseases interfering with evaluation of the block.
