The level of particulate matter on the day of surgery pose a risk of intra-operative hypoxaemia in children receiving general anaesthesia.
Study context
- Population
- Children aged 18 years or younger receiving GA, January 2019 to October 2020finally analysed
- Participants
- 13,175 children
- Exposure
- PM10 ≥81 vs <81 μg m −3 on the day of surgery
- ≥81 μg m −3n = 275
- <81 μg m −3n = 12,900reference
- Outcome
- Intra-operative hypoxaemia (SpO2 <90% for >1 min, manually verified using vital sign registry data at 2 s intervals)
