SummaryExperience with percutaneous dilatational tracheostomy in children is limited. This report discusses two significant complications which occurred following the use of this technique Keywords Surgery; percutaneous dilatational tracheostomy. Complications. ...................................................................................... Correspondence to: Mr D. C. G. Crabbe Accepted: 9 October 1997 Percutaneous dilatational tracheostomy (PDT) is widely used in adults as an alternative to open tracheostomy and complications seem infrequent [1]. The inherent simplicity of PDT has made it attractive as a 'bedside procedure' in the adult intensive care unit. Experience in children is much more limited. A small series of children undergoing PDT was reported in 1994 [2]. Because the long-term safety of the technique has yet to be established in children it is important that serious complications are recorded. We would like to report two children who developed significant complications following PDT.
Case histories
Case 1A 15-year-old girl sustained a severe closed head injury after being hit by a motor car. On admission to hospital she had a Glasgow Coma Score of 5. Prior to transfer to our care, oral tracheal intubation was performed using a size 7.0 cuffed tube (Portex Ltd, Kent, UK). Subsequent cranial computerised tomography (CT) demonstrated a left-sided intraventricular haemorrhage and a contused left temporal lobe. Mechanical ventilation was continued for 5 days with paralysis and sedation. After this period muscle relaxants and sedatives were stopped but, by the 8th day post injury, it became apparent that she remained neurologically obtunded. Cough and gag reflexes were reduced. A percutaneous dilatational tracheostomy was performed the same day using a Cook PDT kit (Ciaglia Percutaneous Tracheostomy Introducer Set, C-PTS-100, Cook Ltd, Letchworth, Herts., UK). No complications were encountered during the procedure, which was performed on the paediatric intensive care unit and following the manufacturer's instructions. The tracheostomy was sited between the first and second tracheal cartilages and a size 7.0 cuffed Portex tracheostomy tube was inserted. The tracheostomy tube cuff was inflated for the first 5 days and then deflated after weaning from mechanical ventilation.Mechanical ventilation was discontinued on the 10th day post injury. The tracheostomy tube was changed electively on day 17 without difficulty. On day 24 the child managed to remove her own tracheostomy tube. It was reinserted with some difficulty but subsequently changed without incident on day 29. On day 35 she again removed her tracheostomy tube but on this occasion recannulation of the tracheostome proved impossible. By this stage the child's general condition had improved considerably and, as she appeared to be breathing through her upper airway without distress, the tracheostome was simply occluded with a dressing.Eighteen days after this accidental decannulation the child's voice was noted to be hoarse. Over the subsequ...
