Randomized Controlled Trial Comparative Study
Deltoid, triceps, or both responses improve the success rate of the interscalene catheter surgical block compared with the biceps response.
The influence of the muscular response elicited by neurostimulation on the success rate of interscalene block using a catheter (ISC) is unknown. In this investigation, we compared the success rate of ISC placement as indicated by biceps or deltoid, triceps, or both twitches. ⋯ Eliciting deltoid, triceps, or both twitches was associated with a higher success rate compared with eliciting biceps twitches during continuous interscalene block.

Postpartum haemorrhage (PPH) is a major risk factor for maternal morbidity and mortality. PPH has numerous causative factors, which makes its occurrence and severity difficult to predict. Underlying haemostatic imbalances such as consumptive and dilutional coagulopathies may develop during PPH, and can exacerbate bleeding and lead to progression to severe PPH. ⋯ Emerging evidence suggests that viscoelastic monitoring, using thrombelastography- or thromboelastometry-based tests, may be useful for rapid assessment and for guiding haemostatic therapy during PPH. However, further studies are needed to define the ranges of reference values that should be considered 'normal' in this setting. Improving awareness of the correct application and interpretation of viscoelastic coagulation monitoring techniques may be critical in realizing their emergency diagnostic potential.

We designed a prospective observational study to assess the effect of preoperative anxiety on hypotension after spinal anaesthesia. ⋯ Preoperative anxiety assessed by VAS had a significant effect on hypotension after spinal anaesthesia.

Anaesthesia-related neurotoxicity in the developing brain has been observed in animal models and suggested by observational human trials. Conclusive, quality evidence directing significant practice change is however lacking. Anaesthetists should be aware of the current evidence and future directions of research into this important area.

The publication of To Err Is Human in the USA and An Organisation with a Memory in the UK more than a decade ago put patient safety firmly on the clinical and policy agenda. To date, however, progress in improving safety and outcomes of hospitalized patients has been slower than the authors of these reports had envisaged. ⋯ We then focus on what we believe is a critical part of the healthcare system that can contribute to safety but also to error-healthcare teams. Finally, we review team training interventions and tools available for the assessment and improvement of team performance and we offer recommendations based on the existing evidence-base that have potential to improve patient safety and outcomes in the coming decade.
