Local anesthetic infiltration is not effective in decreasing post- cesarean section skin pain severity.
Rawal Med J Jan ;36(2):110-3.

Objective: To evaluate the impact of skin local infiltration using Bupivacaine on post-cesarean section somatic pain intensity. Subjects and Methods: Our prospective and double-blind study included 81 female patients, aged 32-43 years, American society of anesthesiologists (ASA) physical status I-II and scheduled for cesarean section under balanced general anesthesia at Queen Alia military hospital during the period 2007-2009. Subjects were divided randomly into two groups. Group I (n=43) received skin local infiltration with placebo solution and group II (n=38) received skin local infiltration using Bupivacaine 0.5%. Intramuscular pethidine was administered intra- and post-operatively. Post-operative somatic pain scores using visual analog scale at rest (VASR) and pethidine consumption were recorded during the first 24 hours. Results: There were no significant difference in VASR for pain at 1 hour post-operatively, (G I, 2.4 and G II, 2.6, P>0.05) and pethidine consumption (G I, 25mg and GII, 25mg, P>0.05). Conclusion: Local skin infiltration using Bupivacaine 0.5% was not successful in controlling post-cesarean section somatic pain.
