Abstract:
Objective:To evaluate the effect of continuous pump ropivacaine in rectus sheath in the postoperative analgesia after abdominoplasty.Methods:Patients with abdominoplasty who were admitted to the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from August 2020 to December 2021 were retrospectively analyzed. They were divided into 2 groups: the control group received patient-controlled intravenous analgesia (PCIA) after the operation, sufentanil 100 μg + normal saline diluted to 100 ml, the rate was 2 ml/h, lasted for 48 h, locking time 15 min, Bolus: 0.5 ml; the study group underwent postoperative rectus abdominis intrathecal intubation and continuously infused 0.262 5% ropivacaine saline mixture 100 ml, the rate was 2 ml/h, lasted for 48 h, the locking time is 15 min, Bolus: 0.5 ml. The method of catheter placement in the study group: a catheter was placed unilaterally in the anterior sheath of the rectus abdominis under direct vision, and an incision was made 2 cm below the umbilical plane. The other end is pierced from the umbilicus and connected to the analgesic pump. The visual analogue scale (VAS) for pain and the number of analgesic pump boluses at 24 h and 48 h after operation, the occurrence of postoperative adverse drug reactions and the patient satisfaction at 1 month after operation were collected. The normally distributed measurement data were expressed as Mean±SD, and the comparison between the two groups was analyzed by t-test; the count data was expressed by the frequency (percentage), and the Fisher’s test was used for analysis. Results:A total of 56 patients were included, including 9 males and 47 females, ranging in age from 27 to 53 years old, with ASA graded from 1 to 2, body mass index (BMI) ranged from 26 to 33 kg/m 2. Their rectus abdominis separation ranged from 3 to 7 cm. Compared with the control group, the pain VAS score of the study group at 48 hours after the operation was lower (3.9±1.5 vs. 5.2±1.4, P<0.05), and the number of analgesic boluses was reduced (2.9±0.3 vs. 3.9±0.4, P<0.05), the incidence of adverse reactions such as nausea, vomiting decreased( P<0.05). The satisfaction rate 1 month after operation in the study group was significantly higher than that in the control group [100.0% (30/30) vs. 42.3% (11/26), P<0.05]. Conclusions:Continuous infusion of ropivacaine through anterior rectus intrathecal cannula can effectively relieve abdominal pain after total abdominoplasty, reduce adverse reactions caused by postoperative analgesics, improve patient comfort during hospitalization, and improve overall surgical satisfaction.
