How does intravenous fluids wear off?

Medical Questions: I am not sure if I am missing the point. But, all fluids in your body go through the liver, lungs and kidneys and are used up and cleaned up and excreted. I am not sure why you wonder about this. If I am missing the point then please ask again.

Sugar, salt, lactate: Iv fluids 101. The most common IV fluids uses are some combination and concentration of sugar (glucose, dextrose), salt (saline), and lactate. These combos are generally either isotonic (same concentration as blood), or hypotonic (less so). So, d5w is hypotonic sugar water that would be used for water depleted state; ns (normal saline) for low blood volume state. D5 in 1/2 ns for dehydration....

Is it ok for a patient to take fluids and food orally at the same time when intravenous drip is being administered.

Is it ok for a patient to take fluids and food orally at the same time when intravenous drip is being administered.

Depends on reason: Although there is no inherent danger in drinking or eating while getting IV fluids, it is important to discuss with the physician if they have another reason why one shouldn't be taking anything by mouth. Before surgery, obstruction, etc. Would require a patient to be NPO (nothing by mouth). Discuss with the doctor treating you - they would know best.

What should I expect during and after an intravenous lidocaine infusion?

What should I expect during and after an intravenous lidocaine infusion?

IV?: IV lidocaine may correct temporally an abnormal cardiac rhythm but is not long term therapy. In general patients don't feel anything in particular but be wary if you feel numbness of the tongue/lips and ringing in the ears. That's a sign the lido level is high. If this is epidural, spinal or isolated nerve block there will be a reduction of pain and weakness of the involved nerve.

What to do if I have lidocaine injected intravenously instead of just numbing tissue?

IV Lidocaine: Lidocaine, in low doses, is actually injected intravenously in certain clinical situations. Toxic levels of this medication would first cause neurologic symptoms and then cardiovascular sequelae. If small amounts are injected IV in the process of infiltrating tissue, it is unlikely that one would suffer any major complications.

HIT: HIT is known as heparin-induced thrombocytopenia. There are two forms. Only type II is clinical significant and can be life threatening if not recognized and treated appropriately. It is mediated by an immune mechanism through formation of antibodies against platelet. It occurs in 1-5% of patients exposed to heparin, regardless of the dose or route of administration.
