Researchers Looking for the Best Way to Keep Patients Safe During Anesthesia for Shoulder Surgery

Interscalene blocks are a type of regional anesthesia used to relieve pain during and after shoulder surgery. This procedure can lead to numbing of the phrenic nerve as well, however, which can lead to pulmonary complications. Researchers at Stanford University are experimenting with different amounts of saline that can help reverse the phrenic nerve blockade while still maintaining analgesic effect.
