Of all the poets of the ancient world, Virgil is clearly the one who survived most successfully throughout the Middle Ages, despite the competition of perhaps his closest rival, Ovid. Manuscripts of Virgil were frequent in medieval libraries, and his status as a messianic prophet, founded on the fourth Eclogue, clearly did much to enhance his reput...

Almost all tracheal intubations are performed with the expectation of subsequent extubation. However there is a relative lack of guidance and research regarding this key aspect of anaesthetic care. Respiratory complications around extubation arise in 12% of elective cases, compared to 4.6% in the same patient group at induction.1 If coughing is dis...

The thoracic paravertebral block was first described in the treatment of chronic pain. More recently, the technique has also been used to provide surgical analgesia for a variety of applications, including thoracic, breast, and general surgery. It is possible to provide analgesia lasting into the postoperative period, and certain procedures may be...

e20666 Background: Although there is an emerging trend to reduce blood transfusions, there is still very little randomized data outside of the critical care setting that identifies the risks and benefits of transfusion support. Many clinicians base the decision to transfuse primarily on the hemoglobin (Hb) level independent of symptoms. Little is k...

This article covers the aspects of acute cervical spine injury that are relevant to anaesthetists. The anaesthetist's involvement will range from participating in the resuscitation of patients with polytrauma to the provision of safe anaesthesia to allow surgical treatment for cervical spine or other injuries. The importance of early immobilisation...
