Aplicación intraperitoneal de ropivacaína para control del dolor en cirugía antirreflujo por laparoscopia: estudio aleatorizado doble ciego

Introduction: Postoperative pain in anti refl ux surgery, usually referred to the interescapular area often represents a limiting factor for the patient’s discharge affecting early mobilization and recovery. Material and methods: Comparative, randomized, double-blind trial of 94 patients that required a laparoscopic Nissen fundoplication. 47 patients in group 1, received 0.25 mL/kg of ropivacaine 7.5% spread on both diaphragmatic domes at the end of the procedure. The remaining 47 patients in group 2 did not receive intraperitoneal ropivacaine and were considered as the control group. The main results were obtained through the application of the visual analogue scale for pain at 2 and 6 hours postoperatively. Results: When the perception of pain according to visual analogue scale for pain was assessed, the control group had a higher score with statistically signifi cant difference compared to the group with intraperitoneal application of ropivacaine at 2 and 6 hours of completion of the surgical procedure (2 hours 6.89 ± 1.32 versus 4.91 ± 1.76 p < 0.001 and 6 hours 4.92 ± 1.35 versus 3.62 ± 1.31 p < 0.001). Conclusions: Applying intraperitoneal ropivacaine in antirefl ux surgery is an effective and safe method for postoperative pain control.
