What is mac-bar anesthesia?

Mac-Bar anesthesia, also known as Modified Barden's technique or Baraka's block, is a type of regional anesthesia technique used for upper limb surgeries. It involves the administration of local anesthetics (lidocaine or bupivacaine) along the axillary sheath at the level of the fourth or fifth intercostal space, which blocks the brachial plexus nerve roots. This results in loss of sensation and paralysis of the upper limb.

Mac-Bar anesthesia is a safe and effective regional anesthesia technique that offers many benefits compared to general anesthesia, such as reduced postoperative pain, decreased nausea and vomiting, and faster recovery times. However, like any procedure, it does have potential risks and complications, such as accidental injection into a blood vessel, nerve damage, and infection. Therefore, it should only be performed by trained and experienced healthcare professionals.
