Randomized Controlled Trial Comparative Study Clinical Trial
Surgical tracheostomy versus percutaneous dilatational tracheostomy. A prospective-randomized study with long-term follow-up.
To compare surgical tracheostomy (ST) versus percutaneous dilatational tracheostomy (PDT) in terms of complication rates. In particular we specifically studied the late tracheal complications of both methods by means of endoscopic controls of patients up to 6 months after the procedures. ⋯ This study confirms that PDT is a simpler and quicker procedure than ST and that it has a lower rate of early postoperative complications. Late tracheal complications were more frequent, although the difference was not statistically-significant, in the PDT group. Further investigations of long-term outcome following PDT are therefore necessary.

Randomized Controlled Trial Clinical Trial
Renal dose dopamine in open heart surgery. Does it protect renal tubular function?
This prospective, randomized study assessed the effect of dopamine on renal tubular function in patients who had coronary artery bypass grafting. ⋯ Consequently, in patients with normal preoperative renal and cardiac function scheduled for elective coronary artery bypass grafting, renal dose dopamine infusion alone may not provide sufficient protection on tubular function and increases renal tubular injury during the early postoperative period.
