Objective:
To investigate the postoperative analgesic effects of rectus sheath block (RSB) in combination with patient-controlled analgesia (PCA) compared with PCA alone after single-port total laparoscopic hysterectomy (TLH).
Methods:
This randomized, single-blind study enrolled female patients that underwent single-port TLH. The patients were randomized to receive either fentanyl PCA (PCA group) or RSB with the same PCA. The primary outcomes were fentanyl consumption at 8 h postoperatively and visual analogue scale (VAS) pain scores, which represented the severity of postoperative pain.
Results:
A total of 36 patients were enrolled in the study: 18 in the PCA group and 18 in the RSB group (two patients were excluded). The primary outcome of fentanyl consumption was significantly lower at 8 h postoperatively in the RSB group than in the PCA group (148 ± 61 µg versus 222 ± 107 µg, respectively). VAS scores were significantly lower at arrival in the post-anaesthesia care unit and at 30 min after arrival in the RSB group compared with the PCA group. There were no significant differences in the nausea/vomiting score and in additional analgesic consumption between the two groups.
Conclusions:
RSB can be used as a multimodal approach for pain control in single-port TLH procedures.Clinical Research Information Service (no. KCT0001461).
