Continuous IV Checklist

Administering Intravenous Push Medication Through an Existing Infusion (Continuous IV)

1.

Start hand hygiene and wear a suitable glove.

2.

Check doctor order and review patient file for allergies.

3.

Check medication compatibilities with current active medications.

4.

Verify rate of administration.

5.

Start preparing the required dose.

6.

Verify correct patient.

7.

Assess IV for signs and symptoms of infiltration or phlebitis (and if present, stop until new IV site is obtained).

8.

Turn off IV by turning off pump and/or clamping the tubing directly above the access port.

9.

Swab access port with alcohol or other antiseptic agent according to institutional policy.

10.

If medication is not compatible with IV solution, flush IV line with 2 to 5 mL of normal saline before administration of medication. If medication is compatible with IV solution, normal saline flush is not necessary; continue to next step.

11.

Connect medication syringe to access port via needleless adaptor.

12.

Pull back on plunger of syringe to observe blood return (which verifies placement of IV in vein).

13.

Gently instill medication over required time frame (typically 2 to 5 minutes).

14.

Assess patient carefully during administration for any adverse reactions.

15.

Disconnect syringe when medication is completed.

16.

Flush IV line with 3 to 5 mL of normal saline, instilling at same rate of medication administration in order to administer the medication left in tubing at proper infusion rate.

17.

Turn IV back on or unclamp tubing, then readjust rate appropriately.

18.

Dispose of syringe in sharps container.

19.

Remove gloves, perform hand hygiene, and document medication administration.

First Order Vs. Zero Order Kinetics

Trying to understand first order and zero order kinetics

{My own study points.}

First Order Kinetics

  • Higher plasma concentrations means higher metabolization rate.
  • Metabolism is directly proportional with drug concentrations.
  • Drug is eliminated from the body related to the plasma levels.
  • Constant half-life. (Metabolize 50% of drug)

Zero Order Kinetics

  • Higher plasma concentrations doesn't mean higher metabolization rate.
  • Metabolism is independent from plasma concentrations.
  • Drug concentration in the body increase with time disregarding the elimination rate leading to toxic side effects.
  • Constant rate of drug metabolism.

Conclusion:

First order is Good, Zero order is BAD.

First order is occurring with most medications.


First order: constant proportion of the drug is eliminated per unit time.
Zero order: constant amount of the drug is eliminated per unit time.

Doxorubicin chemo preparation

Doxorubicin MOA

Doxorubicin inhibits DNA and RNA synthesis by intercalation between DNA base pairs by inhibition of topoisomerase II and by steric obstruction. Doxorubicin intercalates at points of local uncoiling of the double helix. Although the exact mechanism is unclear, it appears that direct binding to DNA (intercalation) and inhibition of DNA repair (topoisomerase II inhibition) result in blockade of DNA and RNA synthesis and fragmentation of DNA. Doxorubicin is also a powerful iron chelator; the iron-doxorubicin complex can bind DNA and cell membranes and produce free radicals that immediately cleave the DNA and cell membranes.

Questions:

For those who prepare chemotherapy, we always need detailed guidelines for the preparation of Doxorubicin, and all the chemo handling and preparing precautions.

Does your preparation depend on the route of administration?

Do we use the beads in all preparations, or only for the chemoembolization? 

Do we only need a chemo vertical laminar flow hoods, or the equipment we use should ensure closed system?

Answers:

Doxorubicin is like any other hazardous drug that requires to be prepared under certain conditions stated in USP 800. You may refer to the latest version online. It should answer all your question regarding the precautions you must follow. Closed system devices are not enough by itself to prepare biohazard meds including chemotherapy without a primary engineering control device.

Doxorubicin is mixed with beads for particular procedure called chemoembolization in hepatocellular carcinoma and its given as intra-arterial injection by a trained provider (usually radiologist). But it is never mixed with beads for other routes.

Doxorubicin is given intravenously as a push, intermittent infusion, or continue infusion. This is usually decided by the treatment protocol you would use. For example, in AC protocol (doxorubicin and cyclophosphamide) for breast carcinoma, doxorubicin is given as IV push over 10-12 minutes. While in a more complicated protocol such as R-EPOCH, it is combined with other chemotherapy drugs and is infused as a continuous infusion over 24 hours for multiple days.

How tech is transforming healthcare

How tech is transforming healthcare

1

Wearables

Data captured from health devices could provide precious information to provide accurate care to the patients.
As we noticed wearable gadgets are increasing in numbers as well as accuracy.

2

Augmented Reality

Allowing the healthcare providers to jump instantly between patients, or view organs, or even project radiology images over the body during operations to reduce mistakes.
Combining live video-streaming with Augmented Reality surgeons carrying out operations are able to consult the other side of the world. Who says that you can’t be in two places at once?

3

Online Consultation

The patient, who can afford it, can always consult with their preferred healthcare providers online and even afford a sort of on-call medical service, other than emergency services.

Improving Patient’s Safety By Controlling The Doctor Orders For Ranged Dose Or Ranged Frequency.

Improving Patient’s Safety By Controlling The Doctor Orders For Ranged Dose Or Ranged Frequency.

Are you familiar with range orders for medications like MORPHINE 2-9MG IV Q6hr PRN at your facility? Does your hospital policy contains any restrictions on these orders?! And in case of a ranged order; how does the nurse determine the exact dose to be given and at which frequency?!

Where I work, we do allow them, and the nurse is giving all the needed training for pain assessment. We’re also using an electronic system, where prescriber must enter the required indication for each scenario. And not leaving the medication order prune to error and assumptions of the other healthcare staff.

Other hospitals might only allow one range... perhaps dose or maybe frequency! Yet, in both cases, the physicians must clearly enter the required dose range [i.e. for pain score 1-3 give 2MG, for pain scale 4-9 give 4MG …. etc.]

In some cases if the physician does not specify – the lowest dose and shortest frequency are used. A nurse must start at the lowest dose unless the patient has recently received a higher dose of the medication (or equivalent)

During the doctor's entry for the ranged order, they were using a free text field, and that doesn’t really help our clinical support system. That's why in most cases we had to verify the ranged doses manually and double checking them while dispensing and administration.

For orders with insulin doses from our insulin pumps and doses from our PCAs; ranged orders are required.

For non-pain medications, we instruct the nurse to start low and assess for effect, then proceed as necessary to address the condition.   Also have a Pain Management policy that guides the nurse to choose the pain order and dose that matches the pain score obtained from the assessment of the patient pain medication asks the prescriber to choose a Pain severity (mild, moderate or severe), all of which have scores assigned to them in the policy. For example, if the dose range is 1-2MG when mild pain, and the patient expressed the higher end of that range, then the nurse would choose 2MG.  If there are multiple products ordered, the nurse first picks the one attached to the pain score and then determines the dose which gives the nurse a guideline, but allows some flexibility in adjusting to the patient response.
