Randomized Controlled Trial
Differential effects of serum from patients administered distinct anaesthetic techniques on apoptosis in breast cancer cells in vitro: a pilot study.
In vitro and retrospective clinical studies suggest an association between anaesthetic technique during primary breast cancer surgery and cancer outcome. Apoptosis is an important step in the mechanism of breast cancer metastasis, but whether it is influenced by anaesthetic technique is unknown. Using serum from breast cancer surgery patients randomized to receive distinct anaesthetic techniques, we investigated its effect on apoptosis in oestrogen receptor (ER)-negative breast cancer cells in vitro. ⋯ Serum from patients given sevoflurane anaesthesia and opioids for primary breast cancer surgery reduces apoptosis in ER-negative breast cancer cells to a greater extent than serum from patients given propofol-paravertebral anaesthesia. Anaesthetic technique might affect the serum milieu in a manner that impacts cancer cell apoptosis, and thereby tumour metastasis.

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.

Multicenter Study
Major incidents and complications in otherwise healthy patients undergoing elective procedures: results based on 1.36 million anaesthetic procedures.
Improved anaesthesia safety has made severe anaesthesia-related incidents, complications, and deaths rare events, but concern about morbidity and mortality in anaesthesia continues. This study examines possible severe adverse outcomes or death recorded in a large national surveillance system based on a core data set (CDS). ⋯ This is the first study assessing severe incidents and complications from a national outcome-tracking database. Annual identification and review of cases, perhaps with standardized database queries in the respective departments, might provide more detailed information about the cascades that lead to unfortunate outcomes.

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).

Review Meta Analysis
Dexamethasone and haemorrhage risk in paediatric tonsillectomy: a systematic review and meta-analysis.
Summary In children undergoing tonsillectomy, dexamethasone is recommended to reduce the risk of postoperative nausea and vomiting while non-steroidal anti-inflammatory drugs (NSAIDs) are used for pain relief. We aimed to determine whether children who receive dexamethasone or dexamethasone with NSAID are more likely to experience haemorrhage post-tonsillectomy. Randomized and non-randomized studies in which children undergoing tonsillectomy received dexamethasone or dexamethasone and NSAID were sought within bibliographic databases and selected tertiary sources. ⋯ Clinical heterogeneity was observed between studies. The pooled analysis did not demonstrate a statistically significant increase in the risk of post-tonsillectomy haemorrhage with dexamethasone with/without NSAID use in children. However, the majority of the included studies were not designed to investigate this endpoint, and thus large studies which are specifically designed to collect data on haemorrhage rate are needed.
