What IV solution is used for chest pain patients?!

Best Answer - Chosen by Voters

Not all patients are treated the same way. I've worked in CCU for what seems like an eternity and I have never hung Ringers Lactate. There are certain drugs given that are incompatibly with certain IV solutions.
The AC LS protocol recommends Normal Saline with central lines because dextrose creates a medium that encourages infections. Normal saline is hung but is there incase the patient becomes hypotensive.IT'S 3:30 in the morning and that's all I can think of but the first responder has given you a very good answer.

RNCCU

Chest pain can be treated with morphine or nitroglycerin . Morphine 2 to 4 mg IV, repeated q 15 min as needed, is highly effective but can depress respiration, can reduce myocardial contractility, and is a potent venous vasodilator. Hypotension and bradycardia secondary to morphine can usually be overcome by prompt elevation of the lower extremities. Nitroglycerin is initially given sublingually, followed by continuous IV drip if needed.

Normal Saline is most widely used mainly because it has the most compatibility with the drugs out there. The electrolytes in lactated ringers wil crystalize some drugs, valium is one example. Also if for any reason you have to go to surgery you can hang blood in normal saline where you can't in lactated ringers.
