**1. Introduction**

The latest review articles on regional anaesthesia for hip surgery highlight the improvements made in perioperative care combined surgical, anaesthetic and analgesic protocols in order to demonstrate improved perioperative outcomes [1]. The combination of intraoperative spinal anaesthesia with non-opioid adjuvance or low-dose peripheral nerve block (PNB) appears to provide the "ideal" analgesia for hip replacement. The incidence of urine retention requiring catheterisation and postoperative nausea and vomiting is less by avoiding perioperative systemic and intrathecal opioids thus allowing earlier ambulation and discharge. The recent study of Cook et al. confirms that spinal anaesthesia is associated with minimal morbidity of deep vein thrombosis (DVT) and pulmonary embolism (PE) in the majority of cases [2].
