Peripheral nerve blocks for outpatient surgery: evidence-based indications.

Area of Science:

• Anesthesiology
• Surgical Procedures
• Pain Management

Background:

• Peripheral nerve blocks (PNBs) are gaining traction in ambulatory surgery.
• Recent literature provides insights into optimal PNB techniques for outpatient procedures.
• This review focuses on PNB indications for upper extremity outpatient surgery.

Purpose of the Study:

• To review the available literature on indications for peripheral nerve blocks in outpatient upper extremity surgery.
• To identify optimal PNB techniques for specific ambulatory surgical procedures.
• To summarize current evidence regarding PNB utility in the ambulatory setting.

Main Methods:

• Literature review of recent reports on PNBs for outpatient upper extremity surgery.
• Analysis of studies focusing on PNB techniques and indications.
• Synthesis of evidence on the effectiveness of various PNBs for different surgical sites.

Main Results:

• Interscalene brachial plexus block (ISBPB) is the most preferred technique for outpatient shoulder surgery.
• Supraclavicular, infraclavicular, and axillary brachial plexus blocks are effective for arm, forearm, and hand analgesia.
• While technical aspects are often studied, evidence-based indications for ambulatory PNBs require further investigation.

Conclusions:

• ISBPB is the most beneficial PNB for outpatient shoulder surgery.
• Supraclavicular block may serve as an alternative to ISBPB, pending further research.
• Many PNB techniques appear interchangeable for distal upper extremity procedures, necessitating future studies for standardization.
