After minor arthroscopic shoulder surgery, the addition of a continuous interscalene ropivacaine infusion to a single-shot interscalene block reduces pain, especially with movement, during the first 24 hrs.

Continuous interscalene block for ambulatory shoulder surgery in a private practice setting had a high success rate, a low complication rate, and enabled the avoidance of the use of potent opioids in 98% of patients.

Interscalene catheters placed for shoulder surgery using an ultrasound needle end point provide postoperative analgesia that is of similar quality to that obtained when using a neurostimulation needle end point. The ultrasound end point was associated with a reduction in needle under the skin time and procedure-related pain.

After shoulder surgery, interscalene catheters placed with US demonstrated improved effectiveness during the first 24 hrs compared with those placed with NS. These catheters were also placed with less needling and a very small reduction in procedure-related pain.
