[Tracheotomy - surgical and percutaneous].

Modern indications for tracheostomy are the following: support of mechanical ventilation and weaning from mechanical ventilation, prevention of complications due to prolonged endotracheal tube ventilation. Surgical tracheostomy (ST) still plays an important role in the management of respiratory failure despite the wide use of percutaneous dilatational tracheostomy (PDT). Peri- and postoperative complication rates as well as lethality rates of these competing procedures are similar according to the literature.

Effects of whole body cryo-chamber therapy on pain in patients with chronic low back pain: a prospective double blind randomised controlled trial.

Background: It is believed that treatment with low temperature can reduce pain perception in chronic pain patients, including chronic low back pain patients.

Aim: To evaluate the effects of a two-week repeated intervention of -67 °C cryo-chamber in patients with chronic low back pain.

Design: A prospective randomized double blind study design.
