Randomized Controlled Trial
β2-Adrenoceptor gene variants affect vasopressor requirements in patients after thoracic epidural anaesthesia.
While the β2-adrenoceptor pathway is essential for cardiovascular regulation, the impact of ADRB2 gene variations on circulatory responses is unclear, possibly due to neural compensatory mechanisms. We tested the hypotheses that (i) sympathetic block by thoracic epidural anaesthesia (TEA) unmasks the influence on arterial pressure of genetic variations and (ii) vasopressor requirements during TEA depend on ADRB2 gene variation. ⋯ The ADRB2 Glu27 allele is an independent predictor of arterial hypotension and vasopressor requirements after TEA. Neural block can unmask genetic influences on neurohumoral regulation. Clinical trial registration DRKS00005260.

Randomized Controlled Trial
Efficacy of palonosetron for the prevention of postoperative nausea and vomiting: a randomized, double-blinded, placebo-controlled trial.
The aim of this study was to evaluate the efficacy of palonosetron, the latest 5-HT3 receptor antagonist, for the prevention of postoperative nausea and vomiting (PONV) during the first 72 h after operation. ⋯ Palonosetron 0.075 mg i.v. effectively reduced the incidence of PONV during the first 72 h after operation, with most of the reduction occurring in the first 24 h.

Historical Article
National critical incident reporting systems relevant to anaesthesia: a European survey.
Critical incident reporting is a key tool in the promotion of patient safety in anaesthesia. ⋯ We make recommendations for others intending to start new systems and speculate on the prospects for sharing patient safety lessons relevant to anaesthesia at European level.

Observational Study
Postoperative decrease in plasma sodium concentration after infusion of hypotonic intravenous solutions in neonatal surgery.
Hypotonic i.v. solutions can cause hyponatraemia in the context of paediatric surgery. However, this has not been demonstrated in neonatal surgery. The goal of this study was to define the relationship between infused perioperative free water and plasma sodium in neonates. ⋯ Hypotonic solutions and i.v. free water intake of more than 6.5 ml kg(-1) h(-1) are associated with reductions in postoperative plasma sodium measurements ≥4 mM. In the context of neonatal surgery, close monitoring of plasma sodium is mandatory. Routine use of hypotonic i.v. solutions during neonatal surgery should be questioned as they are likely to reduce plasma sodium.

This paper aims to explain the key points and highlight some of the controversies in the development of the British Pain Society's pelvic pain patient pathway map. Many clinicians lack experience and confidence with this group of patients, and this issue is highlighted. Additionally, the difficulties of classification and definitions in this area are discussed in detail. ⋯ Patients suffer from significant distress and disability that often needs specialist assessment and intervention (interdisciplinary). This suggests that an integrated approach is required across the historic boundaries of primary and secondary care. A variety of interventions, including opioids and neuromodulation are recommended in the pathway and the controversies surrounding these inclusions are aired in detail.
