NCT03577730

Brief Summary

The ongoing opioid epidemic is a public health crisis, and surgical patients are particularly vulnerable to opioid-dependency and related risks. Emerging data suggest that caffeine may reduce pain after surgery. Thus, the purpose of this study is to test whether caffeine reduces pain and opioid requirements after surgery. The investigators will also test whether caffeine improves mood and brain function (e.g., learning, memory) after surgery.

Outcome Measures

Primary Outcomes (1)

  • Cumulative Opioid Consumption: Postoperative Opioid Consumption, Oral Morphine Equivalents (mg)

    Postoperative opioid consumption, oral morphine equivalents (mg)

    through postoperative day 3

Secondary Outcomes (9)

  • Acute Pain (Patient-reported) as Assessed by Visual Analogue Scale

    Data gathered from postoperative day 0-3. Final results were based on all values combined over this time period, per protocol.

  • Acute Pain (Observer-reported) as Assessed by Behavioral Pain Scale

    Data gathered from postoperative day 0-3. Final results were based on all values combined over this time period, per protocol.

  • Time Until Anesthetic Emergence

    Duration of time from surgical dressing completion to anesthetic emergence (min); generally expected to be between 10 and 60 minutes

  • Number of Participants With Depression as Assessed by the Hospitalized Anxiety and Depression Scale (HADS-D)

    baseline through postoperative day 3

  • Number of Participants With Anxiety as Assessed by the Hospitalized Anxiety and Depression Scale (HADS-A)

    baseline through postoperative day 3

  • +4 more secondary outcomes

Other Outcomes (9)

  • Caffeine Intake: Number of Caffeinated Beverages (n) Consumed

    postoperative day 0-7

  • Subacute Opioid Consumption: Postoperative Subacute Opioid Consumption, Oral Morphine Equivalents (mg)

    postoperative days 4-7

  • Sleep Disturbances: Incidence (%) of New, Self-reported Sleep Disturbances

    postoperative days 0-3

  • +6 more other outcomes
