SeoulAges 20 years+ - NCT06845215Recruiting
Pain block comparison for abdominoplasty recovery
This trial compares two types of nerve blocks (TAP and ESP) to see which provides better pain relief after tummy tuck surgery. Both are injections near the abdominal muscles that numb the area, and you'll also have a patient-controlled pain pump.
Ankara, KeçiörenAges Any age - NCT06845631Recruiting
