Final answer:
The appropriate option for tourniquet management in this situation would be to deflate the tourniquet and perform general anesthesia.
Step-by-step explanation:
The appropriate option for tourniquet management in this situation would be to deflate the tourniquet and perform general anesthesia. Since the equipment needed for the surgery is not available and it will take approximately 1 hour to get the instruments, it is safer to perform general anesthesia to ensure the patient's airway is protected and maintained throughout the procedure. General anesthesia will allow the patient to remain unconscious and have their breathing controlled by a ventilator.
