Purpose
Rectus sheath block (RSB) is a simple abdominal wall block that can be readily applied. This study evaluated the postoperative analgesic efficacy of ultrasound-guided bilateral RSB in robotic single-site gynecologic surgery. Methods Sixty patients were randomly assigned to the RSB group (n=30) or the control group (n=30). After induction of general anesthesia, patients in the RSB group received ultrasound-guided bilateral RSB with 30 mL of 0.25% ropivacaine. Pain intensity was assessed using a verbal numerical rating scale (VNRS) at 0, 1, 6, 12, 24, and 48 hours postoperatively. Intravenous patient-controlled analgesia was provided to all patients, and fentanyl was administered as rescue analgesia on request. Results VNRS scores at 0, 1, and 6 hours were significantly lower in the RSB group than in the control group (all P<0.05). Rescue fentanyl use in the post-anesthesia care unit was also significantly lower in the RSB group than in the control group (19.8±21.0 μg vs. 46.3±27.6 μg, P<0.001). Subgroup analysis showed that RSB was associated with lower VNRS scores in patients undergoing ovarian surgery or myomectomy, whereas no significant difference was observed in patients undergoing hysterectomy. Conclusion Ultrasound-guided bilateral RSB reduced early postoperative pain and rescue analgesic requirements after robotic single-site gynecologic surgery.

The phase of the menstrual cycle was demonstrated to have an influence on the incidence of postoperative nausea and vomiting (PONV) after gynecologic laparoscopic surgery, but little was known for breast surgery, which was shown to have relatively higher incidence of PONV, >60%. We performed this study to investigate the influence of the phase of menstrual cycle on PONV after breast cancer surgery. A total of 103 patients, who were scheduled for breast cancer surgery under general anesthesia, were recruited, and patients with irregular menstrual cycles, history of previous history of PONV were excluded. Groups were divided in two ways as follows: 1) gynecologic classification: premenstrual and menstrual (days 25 to 6), follicular (days 8 to 12), ovulation (days 13 to 15), and luteal phase (days 20 to 24); 2) menstrual classification: menstrual (days 1 to 8) and non-menstrual (days 9 to 28). PONV were recorded using Rhodes index of nausea, vomiting and retching at postoperative 6 and 24 hours. The overall incidence of PONV during postoperative 24 hours was 35.4%. At the menstrual classification, the incidence of PONV at postoperative 24 hours was higher in the menstrual group than that in the non-menstrual group (16.7% vs. 4.2%, P=0.057). The severity of PONV, measured with Rhodes index of nausea, vomiting and retching was significantly different between menstrual and non-menstrual groups (P=0.034). The duration and severity of the PONV after breast cancer surgery were demonstrated to be prolonged and aggravated during menstruation, respectively. Therefore, consideration of menstrual cycle for scheduling breast cancer surgery could effectively prevent the PONV and reduce medical cost. Citations Citations to this article as recorded by
