Effect of pre-incisional versus post incisional lidocaine infiltration on early post-operative pain after cesarean section

ABSTRACT

The effect of preincisional versus postincisional wound infiltration with lidocaine on pain after cesarean section in 40 adult female patients under general anesthesia was studied, they were divided into two equal groups. The surgical area was infiltrated with 1.5% lidocaine plain [30 ml] either 5 min. before skin incision [group 1] or immediately before skin closure [group 2] pain was evaluated for 6 hours after skin incision [zero time] using verbal rating scale and visual analogue scale at rest, during cough and during mobilization. The results revealed a beneficial effect which was evident in group 1. In group 2, there was significantly more number of patients needed analgesics, with significantly earlier demand and significantly more number and type of analgesic doses requirement. Also, there were higher pain scores in group 2 but they were not significant
