In the event of a detected fall in PTN responses during surgery, what is the protocol?

In the context of intraoperative neuromonitoring, the detection of a decrease in Peripheral Nerve Monitoring (PTN) responses is typically a critical event that warrants prompt action. Informing the surgical team without delay is imperative because a fall in PTN responses may indicate potential neural compromise or damage during the surgical procedure. Such information can lead to immediate interventions or adjustments in the surgical plan to protect the patient's neurological function.

Time is of the essence in surgery, particularly in cases where there is a risk of nerve damage. Prompt communication ensures that the surgical team can assess the situation quickly and take necessary contingencies, such as modifying the surgical technique or re-evaluating the surgical field to mitigate any potential harm.

The other choices align with different aspects of monitoring but may not facilitate the immediate and proactive response that is critical in the event of compromised nerve responses. Intraoperative monitoring is there to provide real-time feedback, and any significant changes should directly lead to action rather than delay or cautious observation.
