title: Can we use lower volume of local anesthetic for infraclavicular brachial plexus nerve block under ultrasound guidance in children?
abstract: OBJECTIVE
  To determine if the infraclavicular brachial plexus block can be applied with lower volume of local anesthetic.
  
  
  METHODS
  Randomised, double-blinded clinical trial.
  
  
  METHODS
  60 patients aged 5-15years with ASA I-II who underwent emergent or elective arm, forearm or hand operations were included in the study.
  
  
  METHODS
  Patients were divided into two groups randomly; standard volume local anesthetic administered group (Group S, n=30) and low volume anesthetic administered group (Group L, n=30).
  
  
  METHODS
  Postoperative pain scores, sensory and motor block durations were noted.
  
  
  RESULTS
  Pain scores (Wong-Baker Face Scale) were evaluated and the results were detected to be similar at all times (30min, 1, 2, 4, 8, 12, 24h). Durations of motor block were 168(±16) minutes and 268(±15) minutes in Group L and Group S respectively and the difference was statistically significant (p<0.001). Durations of sensory block were 385(±26) and 402(±39) in Group L and Group S respectively and no statistically significant difference was detected (p=0.064).
  
  
  CONCLUSIONS
  Similar block success, postoperative sensory block durations and pain scores could be obtained during infraclavicular brachial plexus in pediatric patients with lower local anesthetic volumes.
