Observational Study
Characteristics of children aged 2-17 years undergoing anaesthesia in Danish hospitals 2005-2015: a national observational study.
Provision of paediatric anaesthesia requires careful consideration of the child's cognitive state, unique body composition and physiology. In an observational cohort study, we describe the population characteristics and conduct of anaesthesia in children aged 2-17 years from 1 January 2005 to 31 December 2015. Children were identified from the Danish Anaesthesia Database. ⋯ Complications occurred in 3.3% of anaesthesia episodes among 2-5 year olds compared with 3.7% of anaesthesia episodes among children aged 6-17 years. In conclusion, we found younger children (aged 2-5), compared with older children (aged 6-17) were more frequently anaesthetised for non-surgical reasons, at a university hospital and using inhalational agents. Complications were rare.

Observational Study
Echocardiographic determination of resting haemodynamics and optimal positioning in term pregnant women.
Optimal positioning for anaesthesia in pregnant women involves balancing the need for ideal tracheal intubation conditions (achieved by the head elevated ramped position), with the prevention of reduced cardiac output from aortocaval compression (achieved by left lateral pelvic tilt). No studies have examined the effect on cardiac output of left lateral pelvic tilt in the ramped position. We studied non-labouring, non-anaesthetised healthy term pregnant women who underwent baseline (left lateral decubitus) cardiac assessment using transthoracic echocardiography. ⋯ Left lateral decubitus was most comfortable (p = 0.001), however, there were no differences in comfort levels between ramped with wedge and ramped alone positions. The ramped position without left lateral tilt is safe and acceptable in non-labouring, non-anaesthetised, healthy term pregnant women. Left lateral pelvic tilt may be unnecessary in the head elevated ramped position in term pregnant women.
