To the Editor:
A recent article by Samson et al.1 demonstrates the beneficial effects of euctectic mixture of local anesthetic cream on reducing pain from both needle puncture and from needle redirection during humeral block placement in non-sedated patients.
Patient comfort during regional anesthesia is an important issue. A recent review article examines this issue2 and provides recommendations in this regard.
The ever-expanding role of ultrasound in regional anesthesia will also contribute to enhanced patient comfort and satisfaction. Ultrasound guided nerve blocks can decrease the number of needle passes required and avoid the uncomfortable muscle twitches associated with electrical stimulation.3,4 This is accompanied with an improved quality of block,5,6 faster onset of anesthesia5–8 and decreased volume of local anesthetic,8,9 which all increase patient comfort.
