A workgroup, mainly consisting of gastroenterologists and...

Dear Editor, We read with interest the paper by Ang et al.1 on Singapore guidelines in the use of sedation by non-anaesthesiologists during gastrointestinal endoscopy in the hospital setting.

In 1995, the Royal College of Obstetricians and Gynaecologists published the “Organisational Standards for Maternity Services” in which it was proposed that there be a maximum decision-to-delivery interval (DDI) of 30 minutes for urgent caesarean sections (CS).1 This time standard was arbitrary and not supported by any trials or...

Emergency department (ED) deliveries are uncommon in the Singapore setting, as patients presenting with labour to the ED are sent to the obstetric suites in Kandang Kerbau Women’s and Children’s Hospital (KKH), National University Hospital (NUH) and Singapore General Hospital upon arrival. The same applies to the various private...

Haemolysis of blood samples leads to inaccurate results and often necessitates a repeat sample. Escalating workloads and finite resources are an increasing problem in many Emergency departments (EDs), where many conditions have time-dependent outcomes, and accurate and quick blood results are thus important.
