Trial Summary

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, such as beta-blockers, pregabalin, gabapentin, amitryptillin, nortryptillin, and duloxetin, before participating.

What data supports the effectiveness of the drug combination of Dexmedetomidine and Ketamine for postoperative pain?

Research shows that using dexmedetomidine and ketamine together can help reduce pain after surgery. For example, studies have found that this combination can lower the need for opioids (strong painkillers) and improve pain relief in surgeries like thoracic and femur fracture surgeries.12345

Is the combination of dexmedetomidine and ketamine generally safe for humans?

Research shows that dexmedetomidine and ketamine are often used together in medical settings, such as for pain relief after surgery, and are generally considered safe. However, they can have side effects, so their use is carefully monitored by healthcare professionals.12367

How does the drug combination of Dexmedetomidine and Ketamine differ from other pain management options?

The combination of Dexmedetomidine and Ketamine for postoperative pain is unique because it leverages the calming effects of Dexmedetomidine and the pain-relieving properties of Ketamine, potentially reducing the need for opioids and their associated side effects. This combination can enhance pain relief and extend the duration of analgesia compared to using either drug alone or standard pain management options.148910

What is the purpose of this trial?

Postoperative pain after VATS surgery is significant and associated with moderate to high post operative morphine requirements, which can cause opioid related side effects and delay postoperative recovery. To reduce this requirement, multimodal analgesia with non opioid medication such as dexmedetomidine and ketamine can be used. These drugs have demonstrated significant opioid-sparing properties after various types of surgeries. However, very little is known about their ability to do so in VATS surgery. Also, their relative opioid-sparing properties have not been compared, and it is not known whether their combined use can lead to an additional opioid-sparing effect. The primary goal of this study will be to determine the impact of a combined intra operative infusion of ketamine and dexmedetomidine on postoperative morphine requirements in patients undergoing elective VATS, compared to both these drugs infused separately.The hypothesis is that this combined infusion will lead to a 30% further reduction in morphine requirements, 24h after surgery, compared to both these drugs infused separately.

Eligibility Criteria

This trial is for adults aged 18-80 undergoing elective lung surgery (VATS) who are generally healthy or have mild to moderate systemic disease. It's not for those planning to use regional anesthesia post-surgery, on certain pain medications like beta-blockers or chronic pain treatments, with allergies to the study drugs, pregnant, unable to consent, or facing language barriers.

Inclusion Criteria

My health is good to moderately impaired according to anesthesia standards.
I am scheduled for a lung surgery using a camera-assisted method.

Exclusion Criteria

You are allergic to ketamine or dexmedetomidine.
I take more than 60 mg of morphine daily for chronic pain.

Treatment Details

Interventions

  • Dexmedetomidine and Ketamine
Trial Overview The study tests if combining two non-opioid drugs—dexmedetomidine and ketamine—during surgery can better reduce the need for morphine afterward compared to using each drug alone. The goal is a further 30% reduction in morphine use after VATS when both drugs are infused together.

Findings from Research

A mini-dose combination of esketamine and dexmedetomidine significantly reduced the incidence of moderate-to-severe pain after scoliosis correction surgery, with 65.7% of patients experiencing pain compared to 86.0% in the placebo group.
Patients receiving the combination treatment also reported better sleep quality and lower pain intensity both at rest and during movement, without an increase in adverse events, indicating a safe and effective analgesic strategy.

In a study of 1,630 patients undergoing thoracic pulmonary oncologic surgery, those receiving intraoperative dexmedetomidine and ketamine were more likely to be opioid-free post-surgery (76.6% vs 60.9%, P<0.01).
Despite initial lower pain scores and opioid consumption in the recovery room for the dexmedetomidine + ketamine group, these differences were not significant after adjusting for multiple comparisons, indicating no overall impact on postoperative pain management or opioid use during the hospital stay.

In a study of 90 patients undergoing total abdominal hysterectomy, local wound infiltration with ketamine or dexmedetomidine significantly reduced postoperative morphine consumption compared to a control group, indicating an opioid-sparing effect.
Both ketamine and dexmedetomidine delayed the first request for analgesia and lowered pain scores, with ketamine showing superior results in reducing stress markers post-surgery.
