Randomized Controlled Trial Comparative Study Clinical TrialPercutaneous tracheostomy: prospective comparison of the translaryngeal technique versus the forceps-dilational technique in 100 critically ill adults.
To compare two different techniques of percutaneous tracheostomy: Griggs' forceps-dilational technique and Fantoni's translaryngeal technique, both performed with the manufacturer's basic kit and with bronchoscopic guidance. ⋯ Serious complications related to percutaneous tracheostomy occurred in 8.5% and 1.8% of the cases in the translaryngeal technique and the forceps-dilational technique group, respectively (p <.001). Technical difficulties were not rare when using the translaryngeal technique (23%). On the basis of our results, we concluded that the forceps-dilation technique is superior to the translaryngeal technique, with fewer technical difficulties and fewer complications for critically ill patients.

The local vascular tolerance to an intravenous infusion of a concentrated glutamine solution in ICU patients.
The beneficial effects of glutamine is well-documented in ICU patients. However, the documentation and control of enteral administration of glutamine is still insufficient. As an adjunct to enteral nutrition, a concentrated dipeptide solution may be given in a central venous line, but administration via a peripheral vein would be preferable. Therefore, we systematically evaluated local vascular tolerance following a concentrated dipeptide infusion in ICU-patients. ⋯ Administration of a glutamine-containing dipeptide concentrate (20%) by peripheral veins is safe in terms of local tolerance, if a strict protocol is adapted for this purpose is used.

A comparison of the effects of manual and ventilator hyperinflation on static lung compliance and sputum production in intubated and ventilated intensive care patients.
Lung hyperinflation is a technique used by physiotherapists to mobilize and remove excess bronchial secretions, reinflate areas of pulmonary collapse and improve oxygenation. Hyperinflation may be delivered by the ventilator or manually, by use of a manual resuscitation circuit, depending upon the respiratory and cardiovascular status of the patient. The effects of manual hyperinflation, with respect to excess bronchial secretions and static lung compliance, have been well-established. There is, however, only limited evidence as to the efficacy of ventilator hyperinflation as a physiotherapy treatment technique. The purpose of the present study was to compare the effects of manual hyperinflation and ventilator hyperinflation on static pulmonary compliance and sputum clearance in stable intubated and ventilated patients. ⋯ Hyperinflation as part of a physiotherapy treatment can be performed with equal benefit using either a manual resuscitation circuit or a ventilator. Both methods of hyperinflation improve static pulmonary compliance and clear similar volumes of pulmonary secretions.

Red blood cell transfusion does not increase oxygen consumption in critically ill septic patients.
Red blood cell (RBC) transfusion is commonly used to increase oxygen transport in patients with sepsis. However it does not consistently increase oxygen uptake at either the whole-body level, as calculated by the Fick method, or within individual organs, as assessed by gastric intra-mucosal pH. ⋯ Hemoglobin increase does not improve either global or regional oxygen utilization in anemic septic patients. Furthermore, RBC transfusion may hamper right ventricular ejection by increasing the pulmonary vascular resistance index.
