Percutaneous versus surgical tracheostomy: a double-blind randomized trial.

OBJECTIVE To compare surgical (SgT) and percutaneous (PcT) tracheostomies. BACKGROUND Percutaneous tracheostomy has been said to provide numerous advantages over classical SgT. METHODS A prospective randomized trial with a double-blind evaluation was used to compare SgT and PcT. SgT and PcT were performed according to established techniques (n = 70). The procedure was performed at the bedside in the intensive care unit in 21 cases (30%). The outcome measures were divided into procedure-related variables, perioperative complications, and postoperative complications. The procedure-related variables (location, duration, and difficulty) were evaluated by the surgeon. The perioperative and postoperative complications were divided into serious, intermediate, and minor. Perioperative and early postoperative (14 days) complications were evaluated daily by an intensive care unit nurse blinded to the technique used. Long-term postoperative complications were evaluated 3 months after decannulation by a surgeon blinded to the surgical technique. RESULTS There were no major complications in either group. Most variables studied were not statistically different between the PcT and SgT groups. The only variables to reach statistical significance were the size of the incision (smaller with PcT, p < 0.0001), minor perioperative complications (greater with PcT, p = 0.02), and difficult cannula changes (greater with PcT; p < 0.05). Among nonsignificant differences, difficult procedures and false passages were more frequent with PcT, whereas long-term unesthetic scars were more frequent with SgT. CONCLUSIONS Both techniques are associated with a low rate of serious or intermediate complications when performed by experienced surgeons. There were more minor perioperative complications with PcT and more minor long term complications with SgT.
