Which of the following is a potential complication of procedural sedation?

• A. Respiratory Arrest
• B. Headache after procedure
• C. Abdominal pain
• D. Tremor

Answer: (A)

Breathing problems are a primary risk with procedural sedation because the medicines used can blunt the brain’s drive to breathe and diminish protective airway reflexes. That combination can lead to reduced ventilation, lowered oxygen levels, and in the worst cases, respiratory arrest. This is why respiratory arrest is the most significant potential complication to watch for during and after sedation, and it drives the emphasis on continuous monitoring and readiness to support ventilation or reverse the sedative effects if needed.

Other options like headache after the procedure, abdominal pain, or tremor can occur in some patients, but they are not the direct, life-threatening respiratory risks inherent to the sedation process. The key concept here is that ensuring airway and breathing stability is the priority during procedural sedation.
