Peroperative hypothermia is recognized to increase mortality and morbidity, and the paediatric anaesthetist faces specific challenges resulting from the increased body surface to volume ratio, particularly in smaller children. We describe three children who were consecutive patients on one operating list and sustained severe thermal injuries. ⋯ It is rare for thermal warming devices to cause injury. We review the use of heating mats, and suggest modifications in their manufacture which may minimize the risks associated with heating devices.

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.
