Wound infiltration with a local anaesthetic may be used either to provide anaesthesia for superficial surgery or for postoperative pain relief. In the latter situation, its efficacy is real but remains moderate and usually requires a combination with other analgesics. Ilio-iguinal and ilio-hypogastric block has been shown to have an analgesic efficacy close to that obtained with a wound infiltration but the duration of analgesia may be longer. These blocks remain unfrequently used in adults.
