THE FOLEY CATHETER IN EPISTAXIS MANAGEMENT - A SCIENTIFIC APPRAISAL

The Foley balloon catheter has been used in the management of posterio r epistaxis for several decades. Despite a lack of uniformity in ballo on use, it is frequently successful in arresting haemorrhage. A better understanding of the balloon's characteristics may further increase i ts effectiveness by more appropriate use in some individuals. Inflatio n characteristics were assessed in vitro by measurement of balloon len gth and diameter at various inflation volumes. Deflation of air-filled balloons was found to be consistent for each balloon type. The deflat ion rate was unaffected when BIPP (bismuth-iodoform-paraffin paste) or liquid paraffin soaked gauze were applied to the catheter. Recommenda tions for catheter use are made.
