Anaesthesia

Healthcare relies on high levels of human performance, as described by the 'human as the hero' concept. However, human performance varies and is recognised to fall in high-pressure situations, meaning that it is not a reliable method of ensuring safety. Other safety-critical industries embed human factors principles into all aspects of their organisations to improve safety and reduce reliance on exceptional human performance; there is potential to do the same in anaesthesia. ⋯ Human factors principles are not a substitute for proper investment and appropriate staffing levels. Although applying human factors science has the potential to save money in the long term, its proper implementation may require investment before reward can be reaped. This narrative review describes what is known about human factors in anaesthesia to date.

Randomized Controlled Trial
A randomised controlled trial of the non-inferiority of erector spinae plane block vs. thoracic paravertebral block for laparoscopic nephro-ureterectomy.
Erector spinae plane block and paravertebral block can provide analgesia for abdominal surgery. It is unclear whether erector spinae block is inferior to paravertebral block. We aimed to determine whether sufentanil dose and pain intensity (11-point scale) to 24 h after erector spinae block exceeded those after paravertebral block by no more than 5 μg and 1 point, respectively. ⋯ Median (IQR [range]) pain were 1.5 (1.0-2.0 [0.0-5.3]) after erector spinae block vs. 2.0 (1.0-2.5 [0.0-6.0]) after paravertebral block, median (95% CI) difference 0.3 (0.0-0.5), erector spinae non-inferiority p < 0.001. Adverse events did not differ between groups. Erector spinae block analgesia was not inferior to paravertebral block analgesia after laparoscopic nephroureterectomy.
