patient controlled analgesia (PCA) an apparatus used to relieve acute pain. It consists of a pump attached to an intravenous or subcutaneous injection site and filled with multiple doses of medication that are available when the system is activated by the patient. The pump is programmed to “lock-out” the patient for specified intervals making overdosage unlikely.

relative analgesia in dental anesthesia, a maintained level of conscious sedation short of general anesthesia, usually induced by inhalation of nitrous oxide and oxygen.

Patient discussion about analgesia
Q. NO FEELING IN FEET
A. I am not sure I fully understand the situation. Is this no feeling in your feet a chronic symptom or is it new? Chronic loss of sensation in distal parts of your body can result from diabetes (damage to nerve endings) or also PVD- peripheral vascular disease. It depends on your age and how long you have been experiencing this. The treatment varies depending on the cause. Either way you should have a doctor examine you.
