Review article: Effectiveness and risks of cricoid pressure during rapid sequence induction for endotracheal intubation in the emergency department: A systematic review.

The use of cricoid pressure (CP) to prevent aspiration during rapid sequence induction (RSI) has become controversial, although CP is considered central to the practice of RSI. There is insufficient research to support its efficacy in reducing aspiration, and emerging concerns it reduces the first-pass success (FPS) of intubation. This systematic review aims to assess the safety and efficacy of CP during RSI in EDs by investigating its effect on FPS and the incidence of complications, including gastric regurgitation and aspiration.

Low serum sodium is associated with protein energy wasting and increased interdialytic weight gain in haemodialysis patients.

Background: Low serum sodium (Na) has been associated with decreased body mass index and increased cardiovascular mortality in haemodialysis (HD) patients. We examined the relationship between serum Na and selected nutritional parameters of protein energy wasting that are not affected from the hydration status in a cohort of HD patients.

Methods: Triceps skinfold thickness (TSF), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), handgrip strength (HGS) and subjective global assessment (SGA) were assessed in maintenance HD patients using standard techniques.
