A 2-year-old girl presents with 3 days of vomiting and diarrhoea. On examination, she is clinically dehydrated, but haemodynamically stable. Unfortunately, she fails an oral fluid challenge in the department, so she is admitted and rehydrated enterally via a nasogastric tube (NGT). The new medical student attached to the department, upset by watching a screaming child being pinned down, asks you if anything could have been done to make the procedure less distressing for the patient—she recently listened to an American podcast that recommended nebulised local anaesthetic. You realise you have become somewhat desensitised to procedural distress, feel a little guilty and wonder what evidence exists for using topical anaesthetic agents to reduce the distress associated with NGT insertion (NGTI) in children.
Structured clinical question
In a child requiring NGTI (population), does topical local anaesthesia (intervention), compared with placebo (control), reduce the pain and distress associated with insertion (outcome)?
MEDLINE, PubMed, EMBASE, CINAHL, EMCARE, AMED, HMIC and PsychINFO were searched with the following string:

Only English-language articles were examined.
The last search was performed on 28 October 2019. This search retrieved 361 articles, of which two were included in this systematic review (figure 1). These two studies included a total of 136 children aged between 6 months and 5 years.
NGTI has been rated as one of the most distressing procedures performed in the paediatric emergency setting.1 One study2 showed that, although 98% of surveyed emergency doctors …
