Which analgesic is listed for analgesia during transcutaneous pacing?

• A. Morphine Sulfate
• B. Fentanyl
• C. Hydromorphone
• D. Ketamine

Answer: (A)

Pain control during transcutaneous pacing aims to relieve chest discomfort and blunt the sympathetic response that pain can provoke, which helps maintain a stable rhythm and patient comfort. The analgesic listed is chosen for its balance of effective pain relief and a hemodynamic profile appropriate for pacing. Morphine Sulfate provides reliable, longer-lasting analgesia when given IV, which helps cover the pacing period without frequent dosing. Its venodilating effects can modestly reduce preload and myocardial oxygen demand, which can be beneficial in ischemic chest pain scenarios commonly encountered with pacing. Other options have drawbacks in this context: a rapid-acting opioid like fentanyl, while effective, can cause respiratory depression and may require more careful titration during pacing; ketamine can raise heart rate and blood pressure, potentially complicating rhythm management; hydromorphone is similar to morphine but is less commonly selected in these protocols. So, morphine is listed because of its dependable analgesia with a tolerable hemodynamic impact during transcutaneous pacing.
