[Use of methoxyflurane on acute pain during burn dressing in adult consultation]. / Utilisation du méthoxyflurane sur la douleur aiguë lors du pansement en consultation des brûlés adultes.

ABSTRACT

INTRODUCTION: The objective was to compare the short-term efficacy of methoxyflurane vs. MEOPA on acute pain during burn dressing in consultation, the secondary outcome was to assess the patient's comfort and the quality of the dressing performed. MATERIALS AND METHODS: Monocentric, prospective study from April 2018 to January 2019. Men and women>18 years presenting acute burn on<10% SCT were included. A pain≥4 on the numerical scale (from 0 to 10) at the beginning of the treatment established the indication of methoxyflurane or MEOPA, with randomization done by a nurse. The following data were collected burn description, performed debridement, pain assessment by numerical scale on arrival, at the beginning of care, after 6 to 10 inhalations for methoxyflurane or 3 to 4minutes of inhalation for MEOPA and at the end of care. RESULTS: Sixty patients were included, 30 in each group. There was a decrease of -2.47 points of numerical scale when initiating methoxyflurane against -1.53 points for MEOPA (P=0.08). Patients were significantly less painful when stopping treatment in the methoxyflurane group -4 points vs -2 points (P=0.001). Methoxyflurane significantly improved the debridement of the burn (P=0.018). CONCLUSION: Methoxyflurane is more effective than MEOPA in acute pain in burn dressing, improved patient comfort, and improved dressing quality.
