AB280. SOH26AB_0204. Improving recovery in breast-conserving surgery: an audit of local anaesthetic infiltration, pain, and opioid use at University Hospital Limerick

Breast-conserving surgery (wide local excision) is a major component of breast cancer care in Ireland. Effective analgesia supports mobilisation and reduces opioid-related side effects. National guidelines [Irish Pain Society, The National Institute for Health and Care Excellence (NICE)] recommend multimodal, opioid-sparing strategies, while PROSPECT (2023) advises adding pectoral nerve II (PECS II) or erector spinae plane (ESP) blocks. This audit aimed to assess whether surgeon-delivered local anaesthetic (LA) infiltration alone provides adequate analgesia and examined associations with pain, opioid use, postoperative nausea and vomiting (PONV), and anaesthetic technique.
