About this trial
Improvements in burn care have resulted in increased survival. Despite these improved outcomes one of the leading challenges of burn care remains providing adequate analgesia during routine wound care and dressing changes. The traditional use of narcotics is challenging as the therapeutic window between analgesia and suppression of breathing becomes narrow with the intense pain and high doses of narcotics needed for dressing changes.

Primary outcomes
Burn Specific Pain Anxiety Scale
The experience of the dressing change for the patient will also be assessed using the Burn specific pain and anxiety scale which consists of: 1. Worry about wound-healing 2. Fear of procedural pain 3. Fear of losing control because of pain 4. Fear of pain during dressing change 5. Pain severity 6. Keyed up because of enduring pain 7. Concern about wound healing 8. Preoccupied with pain 9. Tension during dressing change Responses for each item are on a visual analogue scale ranging from "least" to "most". The response is normalized to a value between 0 and 1, representing the location selected on the line, divided by the total length of the line. The responses will be used to examine a possible relationship procedural and non procedural pain between the nurse and the patient.

Visual Analogue Scale for pain
The items are scored on a 100 mm visual analog line with two reference points given values of 0 ("No pain") and 100 ("worst possible pain").
Secondary outcomes
Anxiolytic given
The amount of anxiolytic given one hour prior to the dressing change.

The amount of anxiolytic given during the dressing change.
Anxiolytic given
The amount of anxiolytic given one hour after the dressing change.
