title: Two injection digital block versus single subcutaneous palmar injection block for finger lacerations.
abstract: OBJECTIVE
  We aimed to compare two digital nerve block techniques in patients due to traumatic digital lacerations.
  
  
  METHODS
  This was a randomized-controlled study designed prospectively in the emergency department of a university-based training and research hospital. Randomization was achieved by sealed envelopes. Half of the patients were randomised to traditional (two-injection) digital nerve block technique while single-injection digital nerve block technique was applied to the other half. Score of pain due to anesthetic infiltration and suturing, onset time of total anesthesia, need for an additional rescue injection were the parameters evaluated with both groups. Epinephrin added lidocaine hydrochloride preparation was used for the anesthetic application. Visual analog scale was used for the evaluation of pain scores. Outcomes were compared by using Mann-Whitney U test and Student t-test.
  
  
  RESULTS
  Fifty emergency department patients ≥18 years requiring digital nerve block were enrolled in the study. Mean age of the patients was 33 (min-max: 19-86) and 39 (78 %) were male. No statistically significant difference was found between the two groups in terms of our main parameters; anesthesia pain score, suturing pain score, onset time of total anesthesia and rescue injection need.
  
  
  CONCLUSIONS
  Single injection volar digital nerve block technique is a suitable alternative for digital anesthesias in emergency departments.
