If a patient receiving an interscalene block exhibits bilateral numbness of the chest and neck, what should you do NEXT?

When a patient receiving an interscalene block displays bilateral numbness of the chest and neck, this can indicate a serious complication such as the possibility of a high cervical block or systemic toxicity from local anesthetics. The presence of bilateral numbness suggests that the anesthetic may have spread beyond the targeted area, potentially affecting respiratory function or leading to cardiovascular complications.

Stopping the infusion pump immediately is the appropriate course of action to prevent further delivery of the anesthetic and to mitigate the risk of worsening symptoms. This action reduces the risk of potential adverse effects associated with excessive local anesthetic, such as respiratory depression and decreased cardiac output.

Following this, the healthcare team can address the patient's symptoms more effectively, which may include supporting the patient's airway, providing supplemental oxygen, or notifying the surgical team for further evaluation and management. Prioritizing the cessation of the infusion is vital in ensuring patient safety and addressing any complications in a timely manner.
