Efficacy of Nerve Blockade Performed Prior to Surgical Intervention Versus Following Surgical Intervention

Summary

Nerve blocks, or pain medication injected next to the nerve while patients are asleep, are commonly used for pain management after shoulder surgery and are considered highly effective in decreasing post-operative pain. There are several different ways to give a nerve block. All are effective and safe. The purpose of this research is to determine if one of the available ways to give a nerve block is more effective than the others.

Conditions

• Pain
• Shoulder Injury

Interventions

PROCEDURE

Preemptive Interscalene Block - Single Shot

Interscalene brachial plexus blockade will be performed by the anesthesia team under ultrasound-guidance utilizing 1 ml/kg (to a maximum volume of 20 mls) of 0.2% ropivacaine without epinephrine. Regional anesthesia will be performed following the induction of anesthesia, but prior to the start of surgery. Anesthesia team members determined to be proficient in regional blockade, having performed a minimum of ten successful interscalene brachial plexus blocks previously, will be performing the regional blockade.

PROCEDURE

Postoperative Interscalene Block- Single Shot

Interscalene brachial plexus blockade will be performed by the anesthesia team under ultrasound-guidance utilizing 1 ml/kg (to a maximum volume of 20 mls) of 0.2% ropivacaine without epinephrine. Regional anesthesia will be performed following the completion of surgery with the patient still under general anesthesia. Anesthesia team members determined to be proficient in regional blockade, having performed a minimum of ten successful interscalene brachial plexus blocks previously, will be performing the regional blockade.

PROCEDURE

Preemptive Interscalene Block - Catheter

Interscalene brachial plexus blockade will be performed by the anesthesia team under ultrasound-guidance utilizing 1 ml/kg (to a maximum volume of 20 mls) of 0.2% ropivacaine without epinephrine. A continuous peripheral nerve catheter will then be placed under ultrasound-guidance for continuous infusion postoperatively. Regional anesthesia will be performed following the induction of anesthesia, but prior to the start of surgery. Anesthesia team members determined to be proficient in regional blockade, having performed a minimum of ten successful interscalene brachial plexus blocks previously, will be performing the regional blockade.

PROCEDURE

Postoperative Interscalene Block - Catheter

Interscalene brachial plexus blockade will be performed by the anesthesia team under ultrasound-guidance utilizing 1 ml/kg (to a maximum volume of 20 mls) of 0.2% ropivacaine without epinephrine. A continuous peripheral nerve catheter will then be placed under ultrasound-guidance for continuous infusion postoperatively. Regional anesthesia will be performed following the completion of surgery with the patient still under general anesthesia. Anesthesia team members determined to be proficient in regional blockade, having performed a minimum of ten successful interscalene brachial plexus blocks previously, will be performing the regional blockade.
