Monty sits down with one of the co-organisers of this year's meeting in Orlando and discusses this year's annual conference, "Controversies in perioperative medicine". The discussion encompasses pain relief, opioids, the increased use of ultrasound and the use of particular blocks during abdominal surgery. As ultrasound improves how is perioperative medicine changing? What are the challenges presented by larger patients? What are the potential problems with an ultrasound guided tap block?   Presented by Professor Monty Mythen with his guest Professor Stuart Grant, MB ChB, FRCADirector, Medical Student Education, Duke University School of medicine.   Join the debate and email us at [email protected]
