Continuous peripheral nerve block in forearm for severe hand trauma.

Area of Science:

• Orthopedics
• Pain Management
• Neurosurgery

Background:

• Severe hand trauma often requires emergent surgery, leading to significant postoperative pain.
• Effective pain management is crucial for recovery and preventing complications like chronic pain.
• Current analgesia methods may have limitations in providing sustained relief or preserving function.

Purpose of the Study:

• To evaluate the efficacy and safety of continuous peripheral nerve block (CPNB) for postoperative pain control in severe hand trauma.
• To assess the impact of CPNB on pain scores and the need for rescue analgesia.
• To determine the incidence of complications associated with CPNB in this patient population.

Main Methods:

• A prospective study involving 22 hands undergoing emergent surgery for severe hand trauma.
• Placement of an 18-gauge catheter along peripheral nerves in the distal forearm post-surgery.
• Continuous infusion of 0.2% ropivacaine at 2 ml/h for 7-21 days for postoperative analgesia.

Main Results:

• Low postoperative pain scores were maintained throughout the treatment period.
• A minimal requirement for additional analgesic rescue medications was observed.
• No major complications were reported; one case of mild superficial infection resolved upon catheter removal.

Conclusions:

• Continuous peripheral nerve block is a safe and effective method for managing postoperative pain following severe hand trauma.
• This technique provides sustained analgesia without compromising motor function of extrinsic hand muscles.
• CPNB should be strongly considered as a primary postoperative pain management strategy for severe hand trauma.
