Study summary

Oral trans-mucosal administration is relatively easy and convenient, it also reduces first pass metabolism and has been used successfully for fentanyl, ketamine, and midazolam premedication.

Read the detailed description

The alpha2-adrenoceptor agonist, dexmedetomidine, was originally developed as a sedative and analgesic drug for use in intensive care. However, it has a number of unique pharmacodynamic properties, which also make it useful in anesthesia including; decreased MAC, analgesia without respiratory depression and a significant reduction in catecholamine secretion. Also it has been used off-label as an adjunctive agent for sedation and analgesia in patients in the critical care unit and for sedation during non-invasive procedures in radiology. It also has a potential role as part of anesthesia care to prevent emergence delirium and post-anesthesia shivering.

Oral trans-mucosal administration is relatively easy and convenient, it also reduces first pass metabolism and has been used successfully for fentanyl, ketamine, and midazolam premedication.

The current literature is focused in studying the sedative and analgesic effects of intravenously administered dexmedetomidine. Pharmacodynamics and pharmacokinetic studies undertaken on alternative routes of dexmedetomidine administration are lacking. The pharmacokinetic properties of trans-mucosal administration of dexmedetomidine have been demonstrated in one study only, and the clinical effects of non-parenteral administration of dexmedetomidine have been described in anecdotal case reports.

Secondary outcomes

  1. Sedation preoperative

    Sedation score is recorded pre-operatively every 5minutes for 30 minutes after OTM DEX administration

    Time frame: 30 minutes

  2. Blood pressure preoperative

    Non invasive blood pressure will be recorded every 5 minutes for 30 minutes after OTM DEX administration.

    Time frame: 30 minutes.

  3. Heart rate preoperative

    Heart rate will be recorded every 5 minutes for 30 minutes after OTM DEX administration.

    Time frame: 30 minutes

  4. Area under the plasma concentration versus time curve (AUC)

    Two milliliters of blood will be collected for determination of Area under the plasma concentration versus time

    Time frame: 360 minutes.
