Randomized Controlled Trial Comparative Study
A pilot trial of bordered polyurethane dressings, tissue adhesive and sutureless devices compared with standard polyurethane dressings for securing short-term arterial catheters.
To improve arterial catheter (AC) securement and reduce AC failure; to assess feasibility of a large randomised controlled trial. ⋯ AC failure occurred significantly less often with BPU + SPU dressings than with SPU dressings. TA + SPU and SSD + SPU dressings should be further investigated and compared with BPU + SPU dressings as controls. The novel approach of TA + SPU dressings appeared safe and feasible.

Randomized Controlled TrialDexmedetomidine does not reduce emergence agitation in adults following orthognathic surgery.
Patients undergoing orthognathic surgery are at high risk of developing emergence agitation. We hypothesised that a single-dose of dexmedetomidine would reduce emergence agitation in adults with nasotracheal intubation after orthognathic surgery. ⋯ The addition of a single dose of dexmedetomidine (1 μg/kg) to low-dose remifentanil infusion did not attenuate emergence agitation in intubated patients after orthognathic surgery compared with low-dose remifentanil infusion alone. However, single-dose dexmedetomidine suppressed coughing, haemodynamic changes, and pain during emergence and recovery phases, without respiratory depression. Delayed awakening might be associated with this treatment.

Pharmacokinetics of short versus extended infusion meropenem dosing in critically ill patients: a pilot study.
To test whether a prolonged 3-hour infusion of meropenem 500mg achieves an equivalent proportion of time above the minimal inhibitory concentration (MIC) (%TMIC) to that of meropenem 1000mg given over 30 minutes. ⋯ Meropenem at 1000mg over 30 minutes achieved a similar %TMIC to meropenem at 500mg given over 3 hours. Meropenem pharmacokinetics were highly variable from individual to individual.

Benefits of high dose N-acetylcysteine to exacerbation-prone COPD patients.
Although high-dose N-acetylcysteine (NAC) has been suggested to reduce COPD exacerbations, it is unclear which category of patients with COPD would benefit most from NAC treatment. The objective of this study was to compare the effect of high-dose NAC (600 mg bid) between high-risk and low-risk Chinese patients with COPD. ⋯ High-dose NAC (600 mg bid) for 1 year reduces exacerbations and prolongs time to first exacerbation in high-risk but not in low-risk Chinese patients with COPD.

Individual patient data comparative analysis of hydroxyethyl starch 130/0.4 v 4% albumin for fluid resuscitation in critically ill patients: statistical analysis plan.
Recent randomised controlled trials have compared the effects of albumin and hydroxyethyl starch (HES) v crystalloids on patient-centred outcomes in critically ill patients. The Saline v Albumin Fluid Evaluation (SAFE) trial reported patient-centred outcomes at 28 days in 6933 patients assigned to fluid resuscitation with either 4% albumin or 0.9% saline; the Crystalloid v Hydroxyethyl Starch Trial (CHEST) reported patient-centred outcomes at 28 days in 6644 patients assigned to fluid resuscitation with either 6% HES (130/0.4) or 0.9% saline. As the two trials used a common reference fluid (0.9% saline) and had most trial methods and data collection points harmonised, a comparison of 4% albumin and 6% HES (130/0.4) on patient-centred outcomes at 28 days in critically ill patients using the individual patient data from the two trials is feasible. ⋯ We have developed a SAP for the SAFE/ CHEST individual patient data comparative analysis to increase the internal validity of the study and minimise bias.
