Primary Outcome Measures:
  • Clinically significant hypotension (systolic blood pressure <80 mm Hg, diastolic blood pressure <50 mm Hg). [ Time Frame: First 2 hours of study drug administration ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The incidence of a CMHA. [ Time Frame: 2 - 24 hours ] [ Designated as safety issue: Yes ]
  • Incidence of adverse events (AEs) between the 3 loading-dose paradigms [ Time Frame: Post-DEX 24-hour observation period ] [ Designated as safety issue: Yes ]
  • Incidence of paradoxical hypertension [ Time Frame: First 2 hours of the post-DEX observation period ] [ Designated as safety issue: Yes ]
  • Incidence of paradoxical hypertension [ Time Frame: 24-hour post-DEX observation period ] [ Designated as safety issue: Yes ]
  • Amount of analgesics administered [ Time Frame: 2 hours prior, and for the first 2 hours during, study drug administration ] [ Designated as safety issue: Yes ]
  • Amount of sedatives administered [ Time Frame: 2 hours prior, and for the first 2 hours during, study drug administration ] [ Designated as safety issue: Yes ]

Study Population

Initially intubated and mechanically ventilated post-surgical adult male and female subjects in an intensive care setting.


Inclusion Criteria:

  1. Subject or the subject's legally authorized representative has voluntarily signed and dated the informed consent document approved by the Research Ethics Board (REB).
  2. Initially intubated and mechanically ventilated adult post-operative subjects in an intensive care setting (e.g., post operative care unit, post anesthesia care unit, etc.) that are expected to require sedation for at least 2 hours.
  3. Has an ASA classification of 1, 2, 3 or 4.
  4. If female, subject must be postmenopausal, surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy), or practicing at least one of the following methods of birth control:

    • hormonal contraceptives (oral, parenteral or transdermal) for at least 3 months prior to study drug administration
    • intrauterine device (IUD)
    • double-barrier method (condoms, contraceptive sponge, diaphragm or vaginal ring with spermicidal jellies or cream).

Exclusion Criteria:

  1. Subjects <18 years of age.
  2. Subjects with a 2nd degree Mobitz Type II or 3rd degree heart block, unless the subject has a permanent pacemaker or pacing wires are in situ.
  3. Subjects with a known allergy to DEX.
  4. Hypotension based on repeat assessments prior to starting study drug defined as SBP <90 mm Hg or DBP <60 mm Hg.
  5. Pre-existing bradycardia prior to starting study drug defined as HR <50 bpm.
  6. Subjects who, in the opinion of the Investigator, have any other condition where the risks of DEX would be expected to outweigh its benefits (e.g., cardiogenic shock on >2 vasopressors, death anticipated within 48 hours).
