A constant rate infusion/manually controlled infusion (CRI/MCI) of analgesic drugs is a simple and effective means of improving patient comfort. Various formulations can be used as a constant rate infusion; the protocol chosen depends on the patient and the degree of pain experienced or anticipated. First convert pounds into kilograms by dividing pounds by 2.2 (there are 2.2 pounds per kilogram): 11 pounds/ 2.2 pounds per kg (pounds cancel out) = 5 kg Now take the kg and multiply by the dose: 5kg X 2 mg/kg/day (kg cancel out) = 10 mg/day Now divide by the number of hours in a day (24) to get the per hour rate:

A constant rate infusion/manually controlled infusion (CRI/MCI) of analgesic drugs is a simple and effective means of improving patient comfort. Various formulations can be used as a constant rate infusion; the protocol chosen depends on the patient and the degree of pain experienced or anticipated. A constant rate infusion (CRI) is prepared to give a patient a continuous dose of drug in intravenous (IV) fluids. This method is advantageous for administering continuous pain management or for drugs with a short half life, as the drug is maintained at effective plasma concentrations for the duration of the CRI ( Creedon et al, 2012 ).

Learn how to calculate a constant rate infusion (CRI) of a drug that has been added a patient's maintenance fluids. A clinical example is provided demonstrating the medical math used to determine the volume of drug to be added to a fluid bag for effective delivery of the CRI within the patient's maintenance fluids.

Also includes normal laboratory reference ranges for. How to Calculate Dosages* Formula 1By convention, the dosage for many CRI drugs is given as µg/kg/min. The calculations can be confusing since most drugs are available in concentrations of mg/ml and are delivered at a fluid rate of ml/hr. The following formula allows the clinician to "plug in" the numbers and solve for the number of milligrams. Calculating CRI Doses Imagine that you have a 10 kg dog in need of a 10 ug/kg/min CRI of lidocaine. The concentration of lidocaine is 20 mg/ml. How can you use this information to treat your patient? First, multiply the dose by the dog's weight, like you would do if calculating any other drug dosage.

These routes would include delivery by transdermal, subcutaneous, intramuscular, intra-articular and intravenous. Intravenous administration of analgesic agents may be timed to be given intermittently or by constant rate infusion. Practical How to calculate and manage constant rate infusions Megan Brashear Published Online: 31 Jul 2015 https://doi.org/10.12968/vetn.2015.6.6.354 Share Abstract A constant rate infusion (CRI) is a medication continuously administered to a patient and is used to maintain consistent plasma levels of that medication.

A constant rate infusion (CRI) is a medication continuously administered to a patient and is used to maintain consistent plasma levels of that medication. CRIs are commonly administered to patients to achieve appropriate levels of pain management, blood pressure management, sedation, anaesthesia, electrolyte supplementation, insulin, and liquid nutrition via a feeding tube.

A constant rate infusion/manually controlled infusion (CRI/MCI) of analgesic drugs is a simple and effective means of improving patient comfort. Various formulations can be used as a constant rate infusion; the protocol chosen depends on the patient and the degree of pain experienced or anticipated. Constant-rate infusion (CRI) allows continuous low-dose administration of various analgesics. Optimally, CRIs are established prior to tissue damage (i.e., preoperatively) and run for 6 to 12 hours postoperatively. CRI analgesia is also quite effective in management of hospitalized patients with preexisting or persistent medical pain.
