Developing a quality improvement project to tackle the desflurane problem.

Anaesthesia is associated with the routine use of volatile anaesthetic agents, all of which are potent greenhouse gases in varying degrees. Desflurane, in particular, has a high global warming potential and in recent years, there has been a global movement to reduce or remove its usage entirely from operating theatres. We work in a large tertiary teaching hospital in Singapore with deeply entrenched practices of using desflurane to facilitate high turnover of operating theatre cases.

SARS-CoV-2 in migrant worker dormitories: Geospatial epidemiology supporting outbreak management.

Background: Migrant worker dormitories-residential complexes where 10-24 workers share living spaces-account for the majority of cases of SARS-CoV-2 infection in Singapore. To prevent overspill of transmission to the wider population, starting in early April 2020, residents were confined to their dormitories while measures were put in place to arrest the spread of infection. This descriptive study presents epidemiological data for a population of more than 60 000 migrant workers living in two barracks-style and four apartment-style dormitories located in western Singapore from April 3 to June 10, 2020.

Inadvertent spinal injection of ondansetron.

Cesarean sections under spinal anesthesia are now a daily occurrence in most tertiary hospitals. We report the first published case of inadvertent spinal injection of ondansetron without any neurological sequelae in a patient undergoing elective Cesarean section under spinal anesthesia. She did not experience any permanent neurological sequelae, and also did not exhibit any central neuraxial opioid side effects-nausea, vomiting or pruritus.
