About this trial

This is an interventional treatment trial for Acute Pain focused on measuring Older adults, Elderly, Acute pain, IV acetaminophen, IV hydromorphone, Analgesia, Adjunctive analgesia

Eligibility Criteria

65 Years - undefined (Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Acute (less than 1 week in duration) severe pain necessitating use of intravenous (IV) opioids in the judgement of the treating attending physician

Exclusion Criteria:

  • Use of other opioids or tramadol within past 24 hours: to avoid introducing assembly bias related to recent opioid use, since this may affect baseline levels of pain and need for analgesics.
  • Prior adverse reaction to hydromorphone, morphine, or acetaminophen.
  • Chronic pain syndrome: frequently recurrent or daily pain for at least 3 months results in modulation of pain perception which is thought to be due to down-regulation of pain receptors. Examples of chronic pain syndromes include sickle cell anemia, osteoarthritis, fibromyalgia, and peripheral neuropathies.
  • Alcohol intoxication: the presence of alcohol intoxication as judged by the treating physician may alter pain perception.
  • Systolic Blood Pressure (SBP) <100 mm Hg: Opioids can produce peripheral vasodilation that may result in orthostatic hypotension.
  • Heart Rate (HR) < 60/min: Opioids can cause bradycardia.
  • Oxygen saturation < 95% on room air: For this study, oxygen saturation must be 95% or above on room air in order to be enrolled.
  • Use of monoamine oxidase (MAO) inhibitors in past 30 days: MAO inhibitors have been reported to intensify the effects of at least one opioid drug causing anxiety, confusion and significant respiratory depression or coma.
  • Patients using transdermal pain patches

Outcomes

Primary Outcome Measures

Change in Pain Intensity, Baseline to 60 Minutes After Medication Infused
Pain intensity is measured on the numerical rating scale (NRS) from 0 (no pain) to 10 (worst pain imaginable). Change in pain intensity is calculated by subtracting pain intensity at 60 minutes from pain intensity at baseline [e.g. Change = NRS(baseline) - NRS(60 min)]. Note that a positive change number indicates that pain score decreased after medication was given, while a negative change number indicates that pain score increased after medication was given.

Secondary Outcome Measures

Change in Pain Intensity Over Time
Pain intensity is measured on the numerical rating scale from 0 (no pain) to 10 (worst pain imaginable). Change in pain intensity is calculated by subtracting pain intensity at a later time point from pain intensity at baseline [e.g. Change = NRS(baseline) - NRS(15 min)]. Change over time is from baseline to a series of time points: 5 minutes, 15 minutes, 30 minutes, and 45 minutes
