The late effect of intraoperative wound infiltration with local anaesthetic in surgical patients; is there any? A randomized control trial

•Intraoperative wound infiltration (IOWI) with local anaesthetic (LA) is commonly in clinical practice.•Apart from the immediate action it has been supported that a down regulation of pain receptors may lead to longer effects.•This RCT aimed to answer this question: i.e whether there is a late effect of the wound infiltration with local anaesthetic.•IOWI with LA offers no further benefit apart from that of the immediate PO period. There is no late effect for pain control.
