What adverse effect may arise from the use of Succinylcholine?

The correct response is hyperkalemia, which is a potential adverse effect associated with succinylcholine administration. Succinylcholine is a depolarizing neuromuscular blocker commonly used for intubation and muscle relaxation during surgical procedures. One key mechanism of action of succinylcholine is that it causes an influx of potassium ions into the extracellular space, particularly in patients who have certain underlying conditions, such as burns, trauma, or neuromuscular disorders. This can lead to elevated levels of potassium in the blood, known as hyperkalemia, which can have serious cardiovascular implications, including arrhythmias and potential cardiac arrest.

Understanding the other adverse effects listed provides context: hypotension, while a possible reaction in some cases, is not a commonly reported effect directly linked to succinylcholine. Bradycardia can occur but is more associated with the vagal response rather than direct effects of the drug. Respiratory depression is a concern when neuromuscular blockers are used, as they cause paralysis of respiratory muscles, but succinylcholine's primary adverse effect to monitor for is hyperkalemia, particularly in vulnerable populations.
