About this study

Official title: Combination of Nalbuphine and Dexmedetomidine Versus Sufentanil and Dexmedetomidine on Patients After Laparoscopic Gastrointestinal Surgery: A Double-blind, Randomized, Controlled Clinical Study

Surgical pain refers to pain that occurs immediately after surgery, including physical pain and visceral pain. Thus, it severely challenges the proper use of analgesics for patients undergoing laparoscope gastrointestinal surgery to clinicians.

Nalbuphine is a mixed agonist-antagonist opioid. The investigators hypothesized that the clinical effect of nalbuphine in combination with dexmedetomidine might be different from that of sufentanil in combination with dexmedetomidine.

So, the investigators performed a nalbuphine and dexmedetomidine dose finding study, for the patient controlled anaesthesia (PCA) after the laparoscopic gastrointestinal surgery, to establish their 95% effective dose (ED95). The investigators then compared the clinical effect and adverse events of the newly established dosing regimen of nalbuphine combined with dexmedetomidine, to the equivalent dosing of sufentanil combined with dexmedetomidine, in the same patient population.

Read the detailed description

Surgical pain refers to pain that occurs immediately after surgery, including physical pain and visceral pain. Appropriate perioperative analgesia is a fundamental component of enhanced recovery after surgery. Especially, 45% of postoperative patients experience inadequate pain after gastrointestinal surgery, and uncontrolled postoperative pain prompts respiratory distress, delays wound healing, and a potentially eventual transition from acute to chronic pain problems. Thus, it severely challenges the proper use of analgesics for patients undergoing laparoscope gastrointestinal surgery to clinicians.

Sufentanil is one of the most common opioid used in patient-controlled analgesia (PCA), it may induce many adverse events including respiratory depression, nausea, vomiting, constipation, urinary retention, pruritus, and drowsiness. Many drugs have been combined with dexmedetomidine in PCA to augment analgesic effect or to reduce the adverse events.

Nalbuphine is a mixed agonist-antagonist opioid. Nalbuphine derives its analgesic and sleep-producing effects through agonism at the kappa-opioid receptor with fewer opioid-induced adverse effects. some articles show that it also has the potential to attenuate the mu-opioid receptor-related adverse events. The investigators hypothesized that the clinical effect of nalbuphine in combination with dexmedetomidine might be different from that of sufentanil in combination with dexmedetomidine. Unfortunately, the optimal dosing of nalbuphine combined with dexmedetomidine for the PCIA after the laparoscopic gastrointestinal surgery, has not been determined.

So, the investigators performed a nalbuphine and dexmedetomidine dose finding study, for the PCIA after the laparoscopic gastrointestinal surgery, to establish their 95% effective dose (ED95). The investigators then compared the clinical effect and adverse events of the newly established dosing regimen of nalbuphine combined with dexmedetomidine, to the equivalent dosing of sufentanil combined with dexmedetomidine, in the same patient population.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Meng Lv (15169105373, qylvmeng@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analogue Scale (VAS) at rest (time frame: At 24 hour after operation). 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.

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 4 Apr 2023.
