Editorial Comment
Intra-operative high inspired oxygen fraction does not increase the risk of postoperative respiratory complications: Alternating intervention clinical trial.
The WHO recommends routine intra-operative and early postoperative use of high inspired oxygen concentrations (hyperoxia). However, a high intra-operative inspired oxygen fraction (FiO2) might result in an increased risk of postoperative respiratory complications. ⋯ Intra-operative hyperoxia did not change the postoperative SpO2/FiO2 ratio or the risk for pulmonary complications. Clinicians should not refrain from using hyperoxia for fear of provoking respiratory complications.

Randomized Controlled Trial
Metamizole vs. ibuprofen at home after day case surgery: A double-blind randomised controlled noninferiority trial.
NSAIDs and paracetamol are the cornerstones of pain treatment after day case surgery. However, NSAIDs have numerous contraindications and consequently are not suitable in up to 25% of patients. Metamizole is a non-opioid compound with a favourable gastro-intestinal and cardiovascular profile compared with NSAIDs. ⋯ Paracetamol/metamizole and paracetamol/ibuprofen are equally effective in treatment of acute postoperative pain at home after ambulatory surgery with comparable patient satisfaction levels.

Randomized Controlled Trial
Improvement in postoperative pain control by combined use of intravenous dexamethasone with intravenous dexmedetomidine after interscalene brachial plexus block for arthroscopic shoulder surgery: A randomised controlled trial.
Intravenous dexamethasone or dexmedetomidine is reported to prolong the duration of analgesia after single-shot interscalene brachial plexus block (ISBPB). However, the effect of co-administration of these agents on the duration of analgesia has not been evaluated. ⋯ Co-administration of intravenous dexamethasone (0.11 mg kg) with dexmedetomidine (1.0 μg kg) significantly prolonged the time to first rescue analgesic request after single-shot ISBPB in patients undergoing arthroscopic shoulder surgery.

Observational Study
Is 'anxiety sensitivity' predictive of postoperative nausea and vomiting?: A prospective observational study.
Postoperative nausea and vomiting (PONV) is an extremely distressing side effect for patients. Despite PONV prophylaxis guided by well established scoring systems, the incidence of PONV is still high. ⋯ In addition to the well established risk factors, anxiety sensitivity can help to predict the risk of PONV. It seems justifiable to add psychological factors such as anxiety sensitivity to PONV risk-scores. PONV prophylaxis should be considered when anxiety sensitivity is high.
