Sir, what is the dose of sodium fluorescein used?

Thanks for the good question. I inject 3mg/kg of fluorescein (bolus, IV) at the time of patients’ intubation.  There is usually a 30-45 minutes delay between injection and resection. If this time interval is not respected, the operative field will be contaminated with additional amount of fluorescein, complicating tumor contrast differentiation.
