Abstract
OBJECTIVES: Efficient pain control is important for patients with acute pancreatitis who visit the emergency department (ED). In this randomized controlled trial, the efficacy of erector spinae plane (ESP) block compared to intravenous tramadol was determined to provide effective pain relief in patients with acute pancreatitis in the ED.
METHODS: A single blind randomized controlled study was conducted in the ED enrolling 18–70 years old patients with acute pancreatitis and a numerical rating scale score of > 4/10. Fifty patients were allocated to two different groups: the control group received IV tramadol (1 mg/kg every 6 h) and the ESP group received an ESP block with ropivacaine 0.375% (40 mL). Both groups received fentanyl (1 µg/kg) for rescue analgesia. Pain scores, hemodynamic parameters, and rescue analgesia were assessed. Data were analyzed using SPSS v20, utilizing t tests and Chi squared tests where appropriate.
RESULTS: Baseline demographics were similar between the ESP and control groups (age 41.56 ± 11.85 vs. 43.68 ± 11.55 years, P = 0.367). The ESP group had significantly lower pain scores up to 16 h (e.g. 1 h: 2.28 ± 1.08 vs. 6.12 ± 0.32; P < 0.001), reduced heart rate and mean atrial pressure at 1 h, and fewer patients requiring rescue analgesia (14% vs. 94%; P < 0.001) with lower analgesic consumption (66.14 ± 4.63 µg vs. 113.17 ± 33.24 µg; P < 0.001).
CONCLUSION: ESP block offers better pain relief and hemodynamic stability than IV tramadol in patients with acute pancreatitis, with significantly decreased opioid needs.
