About this study
Official title: Efficacy and Safety of Cocktail of Ropivacaine,sodium Bicarbonate and Dexamethasone for Incision Local Infiltration Analgesia in Patients Undergoing Ambulatory Laparoscopic Cholecystectomy:A Prospective Randomized Control Trial
The goal of this clinical trial is to learn if the use of cocktail of ropivacaine,sodium bicarbonate and dexamethasone for incision local infiltration analgesia in patients undergoing ambulatory laparoscopic cholecystectomy is safe and effective. The main questions it aims to answer are:
Does the cocktail lower the The incidence of moderate to severe pain during movement stages within six hours after surgery.
Read more
Researchers will compare the cocktail to ropivacaine for incision local infiltration analgesia to see if the cocktail works to moderate the postoperative pain of ambulatory laparoscopic cholecystectomy patients.
Participants will:
Receive the cocktail or ropivacaine for incision local infiltration analgesia at the end of the surgery.
Answer the questions about postsurgical pain at rest or during motion(using a Numeric Rating Scale (NRS) of 0 to 10. Pain measurements were performed at 2, 6, 12, 24 hours,3,7,30 days and 3 months postoperatively.
- Being tested
- The cocktail of 0.5% ropivacaine ,5%sodium bicarbonate and 10 mg dexamethasone, 0.5% ropivacaine

What is being measured
The primary outcome is the main question the study is designed to answer.
The incidence of moderate to severe pain（Numerical Rating Scale) during movement stages within six hours after surgery
The result is quantified continuously in a scale from 0 (No pain) to 10 (Worst pain imaginable) points. Acute pain is labeled of a value ≥4 points.
Measured: 2, 6, 12, 24 hours,3,7,30 days and 3 months postoperatively
Secondary outcomes (1)
Number of Participants With Opioid Administration
The administration of opioids in the first two hours of postoperative for necessary reasons (pain ≥4 points) is recorded by the physician in charge.
Measured: 2, 6, 12, 24 hours postoperatively

What does the primary outcome measure?
The incidence of moderate to severe pain（Numerical Rating Scale) during movement stages within six hours after surgery (time frame: 2, 6, 12, 24 hours,3,7,30 days and 3 months postoperatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
