Why should neuromuscular function be monitored when neuromuscular blocking agents are administered?

• A. To assess depth of blockade and degree of recovery
• B. To measure urine output
• C. To monitor pain response
• D. To assess oxygen delivery

Answer: (A)

Monitoring neuromuscular function is essential when neuromuscular blocking agents are used because it reveals how blocked the skeletal muscles are and how quickly they recover. By using peripheral nerve stimulation (often train-of-four) and watching the number and strength of muscle twitches, you can gauge the depth of blockade and determine when recovery is adequate. This guidance helps keep ventilation safe, prevent residual paralysis after the procedure, and allow precise dosing and timely reversal. Other measures such as urine output, pain response, or oxygen delivery do not reflect the current neuromuscular status and thus don’t inform about blockade depth or recovery.
