3.2.1 Reduction in the requirement of analgesics
In the ketamine group, three out of 22 children (13.6%) required rescue medication for pain relief at 60 minutes after administering ketamine mouthwash. This included two children requiring topical lignocaine and one requiring oral paracetamol. In the placebo group, four out of 22 children (18.2%) required the rescue analgesic medication: two required topical lignocaine and two required oral paracetamol. The difference in the requirement of analgesic rescue medication between the two groups was not statistically significant (p=1.000) (Table 2).
