Randomized Controlled Trial Comparative StudyDesaturation following rapid sequence induction using succinylcholine vs. rocuronium in overweight patients.
Rapid sequence induction may be associated with hypoxemia. The purpose of this study was to investigate the possible difference in desaturation during rapid sequence induction in overweight patients using either succinylcholine or rocuronium. ⋯ Succinylcholine was associated with a significantly more rapid desaturation and longer recovery of oxygen saturation than rocuronium during rapid sequence induction in overweight patients.

Randomized Controlled TrialProlonged moderate pressure recruitment manoeuvre results in lower optimal positive end-expiratory pressure and plateau pressure.
In acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), recruitment manoeuvres (RMs) are used frequently. In pigs with induced ALI, superior effects have been found using a slow moderate-pressure recruitment manoeuvre (SLRM) compared with a vital capacity recruitment manoeuvre (VICM). We hypothesized that the positive recruitment effects of SLRM could also be achieved in ALI/ARDS patients. Our primary research question was whether the same compliance could be obtained using lower RM pressure and subsequent positive end-expiratory pressure (PEEP). Secondly, optimal PEEP levels following the RMs were compared, and the use of volume-dependent compliance (VDC) to identify successful lung recruitment and optimal PEEP was evaluated. ⋯ The same compliance increase is achieved with SLRM as with VICM, and lower PEEP can be used, with correspondingly lower plateau pressures. VDC seems promising to identify successful recruitment and optimal PEEP.

Randomized Controlled TrialIntraoperative warming and post-operative cognitive dysfunction after total knee replacement.
Post-operative cognitive dysfunction (POCD) can affect 30% of orthopedic surgery patients. We hypothesized that perioperative temperature has an impact on POCD. ⋯ Perioperative warming was associated with a higher incidence of cognitive dysfunction at 4 days after total knee replacement in patients >65 years of age.

Multicenter StudyPatient satisfaction with care in the intensive care unit: can we rely on proxies?
To investigate whether next of kin can be addressed as proxy to assess patients' satisfaction with care in the intensive care unit (ICU). ⋯ If the patient is unable to rate his satisfaction with care in the ICU, next of kin may be taken as an appropriate surrogate.

A new non-radiological method to assess potential lung recruitability: a pilot study in ALI patients.
Potentially recruitable lung has been assessed previously in patients with acute lung injury (ALI) by computed tomography. A large variability in lung recruitability was observed between patients. In this study, we assess whether a new non-radiological bedside technique could determine potentially recruitable lung volume (PRLV) in ALI patients. ⋯ Using non-invasive radiation-free bedside methods, it may be possible to measure PRLV in ALI/ARDS patients. It is possible that this technique could be used to determine the need for recruitment manoeuvres and to select PEEP level on the basis of lung recruitability.
