Which of the following is not recommended during HMPAO/ECD administration?

During the administration of HMPAO (hexamethylpropyleneamine oxime) or ECD (ethyl cysteinate dimer), patient comfort and the quality of the imaging results are paramount. One important aspect to consider is that the patient must maintain a calm and still position during the procedure to ensure optimal distribution of the radiopharmaceutical and accurate imaging.

While it may seem beneficial to engage the patient in conversation to help ease any potential anxiety, talking to the patient during the actual injection can be counterproductive. It may distract them or cause movement that could affect the procedure. It's essential that the patient stays relaxed and still, allowing for better uptake of the radiotracer and preventing any complications that might arise from fidgeting or sudden movements.

In contrast, dimming the lights helps create a more calming environment, which can help the patient relax. Instructing the patient to keep their eyes and ears open is vital for their awareness and readiness to follow any further instructions. Allowing the patient to rest for a brief period before injection can help stabilize their condition, especially if they have been in a waiting area for some time. Each of these practices is recommended to enhance both the comfort of the patient and the quality of the imaging results.
