Rectus Abdominis and External Oblique Muscle Infiltration Analgesia Clinical Trial
Official title:
Costal Cartilage Donor-site Pain: Does Abdominal Muscle Infiltration Analgesia Work? A Randomized Controlled Clinical Trial of Microtia Patients
Donor-site pain is an adverse effect of autologous ear reconstruction. A well-planned pain management protocol is needed. The objective of this study was to introduce rectus abdominis and external oblique muscle infiltration analgesia (RAM+EOM-IA) in autologous ear reconstruction and to evaluate its efficacy and safety.
Patients were included in two cohorts: intermittent RAM+EOM-IA combined with intravenous patient-controlled anesthesia (IPCA) and IPCA alone. The primary outcome was the numerical rating score (NRS) of pain recorded during 48 h postoperatively. Secondary outcomes included the Barthel index and rescue analgesic consumption. Additionally, areas of sensory block were tested using a cold stimulus. ;
