Randomized Controlled Trial
Does circumferential spread of local anaesthetic improve the success of peripheral nerve block?
The relation between the pattern of local anaesthetic (LA) spread and the quality of peripheral nerve block is unclear. ⋯ DRKS 00003826.

Electroconvulsive therapy (ECT) is associated with at least transient episodes of hypertension and tachycardia. Beta-blocking agents may be indicated to prevent cardiovascular complications and may shorten seizure duration. This review evaluates studies that used beta-blocking agents during ECT to determine which agent has the most favourable outcomes on cardiovascular variables and seizure duration. ⋯ Labetalol has been studied to a lesser extent and may have prolonged cardiovascular effects. The included studies varied in design, methodology, and the amount of exact data provided in the publications. Further study of beta-blocking agents in ECT is clearly necessary.

Randomized Controlled Trial Multicenter Study
Risk of new or recurrent cancer after a high perioperative inspiratory oxygen fraction during abdominal surgery.
Administration of supplemental oxygen in the perioperative period is controversial, as it may increase long-term mortality. Our aim was to assess the association between 80% oxygen and occurrence of subsequent cancer in patients undergoing abdominal surgery in a post hoc analysis of the PROXI trial. ⋯ ClinicalTrials.gov (NCT01723280).

Randomized Controlled Trial
Effect of anaesthetic technique on the natural killer cell anti-tumour activity of serum from women undergoing breast cancer surgery: a pilot study.
Animal models and retrospective clinical data suggest that certain anaesthetic techniques can attenuate immunosuppression and minimize metastasis after cancer surgery. Natural killer (NK) T cells are a critical component of the anti-tumour immune response. We investigated the effect of serum from women undergoing primary breast cancer surgery, randomized to propofol-paravertebral block (PPA) or sevoflurane-opioid (GA) anaesthetic techniques, on healthy human donor NK cell function and cytotoxicity against oestrogen and progesterone receptor-positive breast cancer cells (HCC1500). ⋯ NCT 041857.

Controlled Clinical Trial
Effect of supervised aerobic exercise rehabilitation on physical fitness and quality-of-life in survivors of critical illness: an exploratory minimized controlled trial (PIX study).
Evidence is limited for the effectiveness of interventions for survivors of critical illness after hospital discharge. We explored the effect of an 8-week hospital-based exercise-training programme on physical fitness and quality-of-life. ⋯ Current Controlled Trials ISRCTN65176374 (http://www.controlled-trials.com/ISRCTN65176374).
