title: [Prevention of procedural pain in dressing changes of burn wounds by auricular injection of small-dose fentanyl].
abstract: OBJECTIVE
  To explore the effective method of the prevention and treatment of procedural pain in dressing changes of burn wounds.
  
  
  METHODS
  Ninety patients of burn injury were randomized into 3 groups, 30 cases in each one. In the group A, fentanyl citrate injection was used at corresponding injury area, jiaogan (AH6a, sympathetic nerve), fei (CO14, lung), neifenmi (CO18, endocrine) on ear, 0.25 mL at each point. In the group B, fentanyl citrate injection was applied subcutaneously in the deltoid muscle, 1 mL. In the group C, 0.9% sodium chloride injection was applied subcutaneously in the deltoid muscle, 1 mL. The visual analogue scale (VAS) was used to evaluate the analgesic effect before, during and 10 min after dressing change in the patients of the three groups separately.
  
  
  RESULTS
  It was not different in VAS score before dressing change among the three groups (P> 0.05). Compared with that before dressing change, the pain was not significant and VAS score was not different during and after dressing change in the patients of the group A (both P>0.05), but the score in the patients of the group B and C was different significantly (all P<0.05). The VAS score during and after dressing change in the group A was lower than that in the group B and C (all P<0.05), and the score in the group B was lower than that in the group C (P<0.05).
  
  
  CONCLUSIONS
  Fentanyl injection of small dose at auricular points achieves definite analgesic effect on procedural pain in dressing changes of burn wounds, superior to subcutaneous injection of fentanyl.
