  1. Area blocking between the two groups was recorded. Axillary region dermatomal spread was significantly increased, but T6 and T7 dermatomal spread decreased in the TTP-PECS group. Data are expressed as mean ± SD (39 in the TTP-PECS group and 38 in the TPVB group)
  2. *P < 0.01 or 0.05, versus the TPVB group
