CPET variables are associated with postoperative morbidity. A multivariable model with VO₂ at θ(L) and gender discriminates those with complications after colonic surgery.

A moderate agreement with a wide variation in individual values was observed between noninvasive methods and PaCO(2) in preterm infants in the first 24 hours. Noninvasive monitoring methods cannot be substituted for PaCO(2) analyses in preterm infants during this critical period.

Summary A key factor that may contribute to communication failures is status asymmetry between team members. We examined the effect of a consultant anaesthetist's interpersonal behaviour on trainees’ ability to effectively challenge clearly incorrect clinical decisions. Thirty‐four trainees were recruited to participate in a video‐recorded scenario of an airway crisis. They were randomised to a group in which a confederate consultant anaesthetist's interpersonal behaviour was scripted to recreate either a strict/exclusive or an open/inclusive communication dynamic. The scenario allowed trainees four opportunities to challenge clearly wrong decisions. Performances were scored using the modified Advocacy‐Inquiry Score. The highest median (IQR [range]) score was 3.0 (2.2–4.0 [1.0–5.0]) in the exclusive communication group, and 3.5 (3.0–4.5 [2.5–6.0]) in the inclusive communication group (p = 0.06). The study did not show a significant effect of consultant behaviour on trainees’ ability to challenge their superior. It did demonstrate trainees’ inability to challenge their seniors effectively, resulting in critical communication gaps.
