Brief Summary

Postoperative pain is common, and the pain intensity can be moderate to severe depending on the site of surgery during the first few days after surgery, and an estimated 15% to 45% experience chronic postsurgical pain. When poorly controlled, the pain can have a significant effect on patient recovery. Proper management of postoperative pain is needed to relieve suffering and lead to earlier mobilization, shortened hospital stay, reduced hospital costs, and increased patient satisfaction. The currently proposed clinical use of Dinalbuphine Sebacate is to administer a single dose of NALDEBAIN® intramuscularly approximately 12 to 24 hours prior to the planned surgery for pain relief. Several clinical studies of NALDEBAIN® have been published, such as the use in laparotomy and laparoscopic cholecystectomy. However, toward the arthroscopic shoulder surgery, no article or report has been available publicly yet. The primary objective of this study is to determine the safety and efficacy of single doses of intramuscular NALDEBAIN® on patients scheduled to undergo arthroscopic shoulder surgery.

Detailed Description

This is a randomized, double-blind, placebo controlled study. Patients scheduled to undergo arthroscopic shoulder surgery will be invited to participate in this study. After obtaining the written informed consent, each subject should be sequentially assigned an individual screening number instead of his/her name, chart number or identification. Subjects will be randomized to two groups, DS group and Control group. Both groups should be treated with both routine analgesic regimen and a dose of investigational product. Random numbers and assignment treatment were generated by computer program before this study initiated. Statistical analyses should be performed on the data to compare the two groups. Numerical variables will be present with mean and standard deviation and categorical variables will be present with number and percentage.

Primary Outcome Measures
NameTimeMethod
Acute postoperative pain intensityWithin 1 day after surgery

Mean pain intensity scored by numeric rating scale (NRS). Numerical Rating Scale (NRS) was a 11-point scale on which 0 represented "no pain" and 10 represented the" worst pain ever".

Brief Pain InventoryWithin 1 day after surgery

Mean scores of each item in Brief Pain Inventory (BPI). Patients fill out 11 different NRS that ask about pain intensity and the effect of the pain on their ability to function during various activities of daily living. The severity scores range from 0 (no pain) to 10 (the most severe pain).

Secondary Outcome Measures
NameTimeMethod
Postoperative pain intensityIn postanesthesia care unit (PACU), and 6 hours, 7 days, 90 days, and 180 days after surgery

Mean pain intensity scored by numeric rating scale (NRS). Numerical Rating Scale (NRS) was a 11-point scale on which 0 represented "no pain" and 10 represented the" worst pain ever".

Consumption of analgesicsWithin 7 days after surgery

The consumption of total amount (mg) of supplemental analgesics administered after surgery.

Time to the first dose of rescue medicationUp to 7 days after surgery

Time from the end of surgery to the first rescue medication use.

Brief Pain InventoryAt baseline, 1 day, 7 days, 90 days, 180 days after surgery

Mean scores of each item in Brief Pain Inventory (BPI). Patients fill out 11 different NRS that ask about pain intensity and the effect of the pain on their ability to function during various activities of daily living. The severity scores range from 0 (no pain) to 10 (the most severe pain).

Satisfaction assessed by a 5-point scale7 days after surgery

Each subject should be asked the following question: "How satisfied were you with your post-surgical analgesia"? Subjects should be asked to classify themselves as either: 1=highly satisfied, 2=satisfied, 3=uncertain, 4=dissatisfied or 5=very dissatisfied.

Incidence of adverse eventsWithin 7 days after surgery

The incidence of postoperative adverse events occurring during 7 days after surgery, especially the ones related to analgesics.
