ReviewApplications of 3D printing in critical care medicine: A scoping review.
Although a wide range of medical applications for three-dimensional printing technology have been recognised, little has been described about its utility in critical care medicine. The aim of this review was to identify three-dimensional printing applications related to critical care practice. A scoping review of the literature was conducted via a systematic search of three databases. ⋯ Several studies relating to the use of three-dimensional printing model simulations for spinal and neuraxial procedures reported a high degree of realism, including ultrasonography applications three-dimensional printing technologies. This scoping review identified several novel applications for three-dimensional printing in critical care medicine. Three-dimensional printing technologies have been under-utilised in critical care and provide opportunities for future research.

Long-term outcomes of patients admitted to an intensive care unit with intentional self-harm.
Self-harm is one of the most common reasons for admission to an intensive care unit (ICU). While most patients with self-harm survive the ICU admission, little is known about their outcomes after hospital discharge. We conducted a retrospective cohort study of patients in the Barwon region in Victoria admitted to the ICU with self-harm (between 1998 and 2018) who survived to hospital discharge. ⋯ Cause of death was self-harm in 27%, possible self-harm in 32% and medical disease in 41%. The only factors associated with mortality were male sex, older age and re-admission to ICU with self-harm. Further population studies are required to confirm these findings, and to understand what interventions may improve long-term survival in this relatively young group of critically ill patients.

Diagnosis and incidence of acute kidney injury in a mixed paediatric intensive care unit: Retrospective analysis, 2005 and 2015.
Acute kidney injury (AKI) is common in intensive care patients. While creatinine definitions for AKI have been validated, oliguria criteria are less well evaluated in children. Our study compared the validity and agreement of creatinine and oliguria criteria for diagnosing AKI in a large mixed medical, surgical and cardiac paediatric intensive care unit (PICU), and assessed the significance of their independent and combined effects on predicted mortality relative to paediatric index of mortality (PIM risk of death) on admission. ⋯ Increasing severity of creatinine rise and oliguria confers increasing risk-adjusted mortality, especially for admissions with low PIM3 risk of death. The mortality of patients with AKI defined by oliguria alone is low. Defining AKI by oliguria alone has less clinical utility and may not represent true AKI.

Randomized Controlled TrialEfficacy of different infusion rates of oxytocin for maintaining uterine tone during elective caesarean section: A randomised double blind trial.
Most research in this field has focused on finding oxytocin doses for initiating uterine contractions. Only limited data are available regarding the optimal rate of oxytocin infusion to maintain adequate uterine tone. This randomised, double blind study included 120 healthy term pregnant patients with uncomplicated, singleton pregnancy undergoing elective caesarean section under spinal anaesthesia. ⋯ The incidence of tachycardia (P = 0.726), hypotension (P = 0.321) and nausea/vomiting (P = 0.161) was comparable. To conclude, 5 IU/hour was more effective than 1.25 IU/hour in reducing total blood loss and the incidence of minor postpartum haemorrhage. Thus 5 IU/hour appears to be an optimal oxytocin infusion rate following 1 IU slow intravenous oxytocin injection for the maintenance of adequate uterine contraction in patients undergoing elective caesarean section under spinal anaesthesia.
