About this study
Official title: Postoperative Analgesic Effects of Ultrasound-guided Bilateral Rectus Sheath Block for Laparoscopic Gynecologic Surgery
Rectus sheath block (RSB) is a kind of anterior abdominal wall block. It has postoperative analgesic effect for abdominal surgery with midline incision. Laparoscopic gynecologic surgery is accompanied by significant postoperative pain and usually IV-PCA is used to manage the pain.The purpose of this study is to investigate the analgesic effect of ultrasound-guided RSB to multi-port laparoscopic gynecologic surgery which has incision site at umbilical area. Patients will randomly assigned to two groups, RSB group and Control group. Each patients will assessed for time to first rescue analgesia, verbal numerical rating pain scores, number of rescue analgesic demands, and postoperatively opioids use by IV-PCA by a blinded investigator at 0, 1, 6, 12, 24 and 48 hours postoperatively.
Read the detailed description
Patients of RSB group will be performed ultrasound-guided bilateral RSB after induction of general anesthesia. The procedure will be performed bilaterally and 15 ml on each side, total 30 ml of 0.25% ropivacaine will be injected. After the procedure, a surgery scheduled will be proceeded. Patient of Control group will be proceeded the surgery after induction of anesthesia. All patients will use total 100 ml of IV-PCA containing 800 µg of fentanyl with 150 mg of ketorolac for 48 hours postoperatively. If a patient complains pain more intense than VNRS 4 or demands an analgesic drug, a rescue analgesic would be allowed.

All patients will use total 100 ml of IV-PCA containing 800 µg of fentanyl and 150 mg of ketorolac for 48 hours postoperatively.
| Study group | Role | What they receive |
|---|---|---|
| Rectus sheath block | Experimental | Patients of RSB group will be performed ultrasound-guided bilateral RSB after induction of general anesthesia. After draping the needle insertion site, a 22-gauge, 50-mm needle will be inserted medial to the probe by the in-plane technique and advanced in a lateral direction on just lateral to umbilicus. 15 ml of 0.25% ropivacaine will be injected on the posterior border of rectus muscle. This procedure will be performed bilaterally and total 30 ml of 0.25% ropivacaine will be injected. After the surgery, a bandage will be attached on injection site where is same as the incision site of surgery. All patients will use total 100 ml of IV-PCA containing fentanyl and ketorolac for 48 hours postoperatively. Receives: Procedure: Rectus sheath block; Drug: Ropivacaine; Other: Bandage; Drug: IV-PCA containing Fentanyl and Ketorolac |
| Control | Sham comparator | Patients of Control group will be proceeded a surgery scheduled after induction of general anesthesia without any procedure such as placebo injection. After the surgery, a bandage will be attached on the incision site where is same as the block injection site of RSB group. All patients will use total 100 ml of IV-PCA containing fentanyl and ketorolac for 48 hours postoperatively. Receives: Other: Bandage; Drug: IV-PCA containing Fentanyl and Ketorolac |

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of rescue analgesics (time frame: 48 hours postoperatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02476799, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jun 2015.
