Analgesic effect of combined transversus abdominis plane block and rectus sheath block in laparoscopic cholecystectomy: prospective randomized study

Abstract

BackgroundWe aimed to investigate the combination of the subcostal transversus abdominis plane block and rectus sheath block (ScTAP-RS) versus wound infiltration on opioid consumption and assess effects on pain scores in laparoscopic cholecystectomy (LC). One hundred patients scheduled for LC were included in this study following the local ethics committee approval. Patients were randomized and divided into two groups as group ScTAP-RS and wound infiltration group (group I). After the surgical intervention, in group ScTAP-RS, ScTAP-RS block with 30 ml 0.25% bupivacaine solution was administered by ultrasound, and in group I, 20 ml 0.25% bupivacaine solution was injected in three port incision sites. Patient-controlled analgesia with tramadol was programmed for 24 h postoperatively. Tramadol consumptions and visual analog scale (VAS) scores were evaluated.ResultsCompared to the infiltration group, total tramadol consumption was significantly lower in the ScTAP-RS group between 4 and 12 h. There was no statistically significant difference between the groups in other time intervals. VAS scores were significantly lower in the ScTAP-RS group in the 4th and 8th hours at rest and ambulation. There was no statistically significant difference between the groups for VAS scores at other time intervals.ConclusionScTAP-RS blocks decrease the opioid consumption and pain scores compared to the local infiltration after LC.
