Multicenter Study
Mini fluid chAllenge aNd End-expiratory occlusion test to assess flUid responsiVEness in the opeRating room (MANEUVER study): A multicentre cohort study.
The fluid challenge response in surgical patients can be predicted by functional haemodynamic tests. Two tests, the mini-fluid challenge (mini-FC) and end-expiratory occlusion test (EEOT), have been assessed in a few small single-centre studies with conflicting results. In general, functional haemodynamic tests have not performed reliably in predicting fluid responsiveness in patients undergoing laparotomy. ⋯ In patients undergoing laparotomy the mini-FC reliably predicted fluid responsiveness with high-sensitivity and specificity. The EEOT showed poor discriminative value and cannot be recommended for assessment of fluid responsiveness in this surgical setting.

Randomized Controlled Trial
Ultrasound-guided anterior iliopsoas muscle space block versus posterior lumbar plexus block in hip surgery in the elderly: A randomised controlled trial.
Ultrasound-guided posterior lumbar plexus block is widely used for hip fracture surgery but it requires a change of position, which may be painful. ⋯ The anterior iliopsoas muscle space block had the same effect as the posterior lumbar plexus block on peri-operative analgesia for hip surgery, but with a longer onset time. Therefore, anterior iliopsoas muscle space block can be recommended as a routine technique for hip and lower limb procedures.

Spinal anaesthesia-induced hypotension is frequently reported in patients undergoing caesarean section. Mechanistically, sympathetic blockade reduces the systemic vascular resistance and the left ventricular preload, causing hypotension, which is augmented by aortocaval compression. The corrected blood flow time (FTc) is affected by the preload and is inversely related to the afterload. ⋯ Preanaesthetic carotid artery FTc was a reliable indicator of postspinal hypotension in parturients. Considering the grey zone, Wodey's formula is better than Bazett's formula.

In light of the coronavirus disease-2019 (COVID-19) pandemic, how resources are managed and the critically ill are allocated must be reviewed. Although ethical recommendations have been published, strategies for dealing with overcapacity of critical care resources have so far not been addressed. ⋯ Experts in critical care support the allocation of resources from centres with overcapacity. The results indicate the need for centrally administered allocation mechanisms that are not based on ethically disputable triage systems. It seems, therefore, that there is wide acceptance and solidarity among the European anaesthesiological community that local medical and human pressure should be relieved during a pandemic by implementing national and international re-allocation strategies among healthcare providers and healthcare systems.
