Randomized Controlled Trial
Tracheal intubation in patients with odentogenous abscesses and reduced mouth opening.
Odentogenous abscesses with involvement of the facial or cervical spaces can be life-threatening and often have to be drained under general anaesthesia. Trismus and swelling can make intubation with a Macintosh laryngoscope difficult or even impossible. However, indirect laryngoscopy has been successful when conventional direct laryngoscopy has failed. Therefore, we evaluated the efficacy of the Glidescope laryngoscope in patients with odentogenous abscesses and the improvement in mouth opening after neuromuscular block. ⋯ In patients with odentogenous abscesses, the use of a Glidescope laryngoscope was associated with significantly faster tracheal intubation, with a better view, fewer supporting manoeuvres, and a higher success rate than with a conventional laryngoscope. Improvement of the inter-incisor distance after induction of anaesthesia correlated with the duration of symptoms.

Randomized Controlled Trial
Crystalloid or colloid for goal-directed fluid therapy in colorectal surgery.
Goal-directed fluid therapy has been shown to improve outcomes after colorectal surgery, but the optimal type of i.v. fluid to use is yet to be established. Theoretical advantages of using hydroxyethyl starch (HES) for goal-directed therapy include a reduction in the total volume of fluid required, resulting in less tissue oedema. Recent work has demonstrated that new generations of HES have a good safety profile, but their routine use in the perioperative setting has not been demonstrated to confer outcome benefit. ⋯ Goal-directed fluid therapy is possible with either crystalloid or HES. There is no evidence of a benefit in using HES over crystalloid, despite its use resulting in a lower 24 h fluid balance.

Randomized Controlled Trial Comparative Study
Postoperative pain after abdominal hysterectomy: a randomized, double-blind, controlled trial comparing continuous infusion vs patient-controlled intraperitoneal injection of local anaesthetic.
Local anaesthetics (LA) injected intraperitoneally have been found to decrease postoperative pain. This double-blind randomized study was performed comparing continuous infusion or patient-controlled intraperitoneal (i.p.) bolus injection of LA. The primary endpoint was supplemental opioid consumption during the first 24 postoperative hours. ⋯ A statistically significant opioid-sparing effect was found when patient-controlled levobupivacaine was administered intraperitoneally as needed compared with continuous infusion. This was associated with a faster return of GI function and home-readiness. There was, however, a wide confidence interval in the primary endpoint, opioid consumption.

Randomized Controlled Trial Comparative Study
Comparison of the effects of xenon and sevoflurane anaesthesia on leucocyte function in surgical patients: a randomized trial.
While most anaesthetics are known to suppress immune reactions, data from experimental studies indicate the enhancement of reactivity to inflammatory stimulators under xenon treatment. We investigated the effect of xenon anaesthesia on leucocyte function in surgical patients. ⋯ In vivo, xenon and sevoflurane anaesthesia did not have a pro-inflammatory effect, at least in combination with the types of surgery performed in this study. Notably, the impact of xenon anaesthesia did not differ significantly from sevoflurane anaesthesia with regard to leucocyte function. However, an underestimation of treatment effects due to limited sample sizes cannot be fully excluded.
