Patient outcome during an obstetrical emergency depends on prompt coordination of an interprofessional team. The cognitive aids with roles defined (CARD) is a cognitive aid that addresses the issue of teamwork in crisis management. This study evaluated the clinical impact of implementing the CARD cognitive aid during emergency Cesarean deliveries. ⋯ The CARD cognitive aid did not significantly improve time-based or clinical maternal and neonatal outcomes of emergency Cesarean delivery at our academic maternity unit.

To externally validate an intensive care unit (ICU) mortality prediction model that was created using the Ontario Critical Care Information System (CCIS), which includes the Multiple Organ Dysfunction Score (MODS). ⋯ A risk prediction model primarily based on the MODS shows reproducibility and transportability after intercept recalibration. Risk adjusting models that use existing and feasible data collection can support performance measurement at the individual ICU level.

Impact of leg movement on skin-adductor canal distance: a potential cause for catheter tip displacement?
Catheter-based adductor canal blocks are an effective pain management strategy for total knee arthroplasty. Nevertheless, catheter-based techniques may fail if the tip migrates because of leg movement. This observational study used ultrasound to measure the distance from the skin to the adductor canal (SAC). We tested the hypothesis that leg movements mimicking those occurring during postoperative physiotherapy change the SAC distance. ⋯ Passive leg movements in five standardized positions increase the SAC distance. We speculate that the altered SAC distance associated with passive leg movement may contribute to catheter tip dislodgement and adductor canal block failure.
