A 72-yr-old patient was to undergo a left lumbar plexus block by the posterior approach to achieve postoperative analgesia after hip replacement. The block failed after three unsuccessful attempts to identify nerve structures and a fascia iliaca compartment block was performed. ⋯ She was re-admitted 2 weeks after surgery because of a lower limb motor deficit and a left retroperitoneal haematoma requiring blood transfusion. Clinicians need to be aware of this potential complication of lumbar plexus block in patients receiving thrombphylaxis.

Case Reports
High-frequency oscillatory ventilation and an interventional lung assist device to treat hypoxaemia and hypercapnia.
A male patient accidentally aspirated paraffin oil when performing as a fire-eater. Severe acute respiratory distress syndrome (Pa(o(2))/Fi(o(2)) ratio 10.7 kPa) developed within 24 h. Conventional pressure-controlled ventilation (PCV) with high airway pressures and low tidal volumes failed to improve oxygenation. ⋯ Pa(co(2)) normalized after initiation of ILA. HFOV with a mean airway pressure of 32 cm H(2)O was maintained, but with a higher oscillatory frequency (9 Hz) and very low oscillatory amplitude (25 cm H(2)O). After 6 days, the patient was transferred to a conventional ventilator, and ILA was discontinued after 13 days without complications.
