Randomized Controlled TrialNon-invasive ventilation after extubation in patients with chronic obstructive airways disease: a randomised controlled trial.
Non-invasive positive pressure ventilation (NPPV) is a well established therapy for acute respiratory failure in patients with chronic obstructive pulmonary disease, however its role in post-extubation period is uncertain. The objective of this study was to find the effect of NPPV on rate of re-intubation, intensive care unit and hospital stay, and physiological parameters in severe chronic obstructive pulmonary disease patients after planned extubation. Forty patients with severe chronic obstructive pulmonary disease were randomised immediately after planned extubation to receive NPPV (n=20) or conventional therapy (n=20). ⋯ Reintubation rate among NPPV (15%) and conventional (25%) were similar (P=0.44). The duration of intensive care unit stay after extubation (2.05 +/- 2.15 vs 1.55 +/- 0.82 days, P=0.34) and hospital stay (16.10 +/- 6.29 vs 18.25 +/- 7.91 days, P=0.34) in both groups were comparable. Given the load of chronic obstructive pulmonary disease patients and wide availability of NPPV it is safe to recommend its use in these patients soon after extubation, although clear benefit is not documented in this study.

Randomized Controlled Trial Comparative StudyBedside percutaneous tracheostomy: a prospective randomised comparison of PercuTwist versus Griggs' forceps dilational tracheostomy.
Tracheostomy is considered the airway management of choice for patients who require prolonged mechanical ventilation. The development of percutaneous techniques offers many advantages including the ability to perform the procedure in the intensive care unit. The aim of this study was to compare the controlled rotating dilation method (PercuTwist) and the Griggs' forceps dilational tracheostomy. ⋯ These complications were minor in 18/20 and were not significantly different between the two groups. In conclusion, we consider that the PercuTwist technique is safe despite the longer duration of the procedure. Nevertheless the forceps dilational technique remains our routine procedure.

Randomized Controlled Trial Comparative StudyRandomised controlled trial comparing oral and intravenous paracetamol (acetaminophen) plasma levels when given as preoperative analgesia.
Gastric absorption of oral paracetamol (acetaminophen) may be unreliable perioperatively in the starved and stressed patient. We compared plasma concentrations of parenteral paracetamol given preoperatively and oral paracetamol when given as premedication. Patients scheduled for elective ear; nose and throat surgery or orthopaedic surgery were randomised to receive either oral or intravenous paracetamol as preoperative medication. ⋯ Maximum median plasma concentrations were 19 mg.l(-1) (interquartile range 15 to 23 mg.l(-1)) and 13 mg.l(-1) (interquartile range 0 to 18 mg.l(-1)) for the intravenous and oral group respectively. The difference between intravenous and oral groups was less marked after 150 minutes but the intravenous preparation gave higher plasma concentrations throughout the study period. It can be concluded that paracetamol gives more reliable therapeutic plasma concentrations when given intravenously.
