Ultrasound-guided bilateral erector spinae plane block in laparoscopic colon cancer surgery : A randomized controlled prospective trial.

BACKGROUND: The efficacy of erector spinae plane block (ESPB) for pain control in other surgeries remains an interesting topic of discussion. This study aimed to evaluate the safety and efficacy and quality of recovery of ultrasound-guided bilateral ESPB in laparoscopic surgery for colon cancer. MATERIAL AND METHODS: In this study 50 patients were included and randomly divided into the intervention group (E group, n = 25) and the control group (C group, n = 25). Patients in the E group received general anesthesia with preoperative bilateral ultrasound-guided ESPB, whereas patients in the C group received general anesthesia with saline injection in the erector spinae plane preoperatively. Data on intraoperative and postoperative anesthetic effects and the effect on enhanced recovery after surgery were recorded and analyzed. RESULTS: Rocuronium consumption in the intervention group was 82.80 ± 21.70 mg, which was lower than that in the control group (P < 0.05). Visual analog scale scores at 2, 6, and 24 h after surgery in the intervention group were lower than those in the control group (Fbetween = 34.034, P = 0.000). The time to ambulation, consumption of ketorolac tromethamine, time to oral intake and hospital stay after operation in the intervention group were significantly lower than those in the control group (P < 0.05). The block area at the different baselines was significant (Fbetween = 3.211, P = 0.009). The association between baseline and time was significant (Fbaseline * time = 3.268, P = 0.001). CONCLUSION: This study confirmed that ultrasound-guided ESPB technology is safe and beneficial for patients with colon cancer undergoing laparoscopic colon surgery.
