Final answer:
The rationale for the administration of fentanyl and midazolam before the débridement of a child's burn wounds is to provide pain relief.
Step-by-step explanation:
The rationale for the administration of fentanyl and midazolam (Versed) before débridement of a child's burn wounds is to provide pain relief. Fentanyl is a potent opioid analgesic that helps to reduce pain without loss of consciousness, while midazolam is a benzodiazepine sedative that can also provide relief from pain.
Prior to débridement, the child may experience significant pain due to the burn wounds. Fentanyl and midazolam can be combined to provide a more effective pain management strategy. Fentanyl acts on opioid receptors in the brain and spinal cord, reducing the perception of pain, while midazolam enhances the effects of GABA, a neurotransmitter that inhibits brain activity and induces sedation.
The administration of these medications before débridement helps to ensure that the child is more comfortable during the procedure, allowing for a smoother and less distressing experience.
