Do not take levels if the vancomycin has been started within the last 6 hours, i.e. after 2:00am; instead, wait until the following morning to check levels. Adjust the maintenance infusion dose (by altering the infusion rate) according to the serum levels, using the Continuous IV infusion dose adjustment calculator.
When should Vanco trough be drawn?
Trough: just before 4th dose of a new regimen (prior to 3rd dose for dosing intervals ≥ 24 hours or changing renal function) – Trough levels should be obtained within 30 minutes before the next scheduled dose. – Weekly vancomycin levels should be obtained for long-term vancomycin use with stable renal function.
When should vancomycin peak and trough levels be drawn?
Do not draw specimens until steady state is achieved (ie, before fourth dose) Draw trough specimen immediately before (≤30 min) next dose. Draw peak specimen 1-2 hours after completion of intravenous dosage.
How long is Vanco trough good for?
Stability Requirements Temperature Period Room temperature 3 days Refrigerated 14 days Frozen 14 days Freeze/thaw cycles Stable x3.
What do you do when Vanco trough is high?
If the high trough level appears genuine, use the vancomycin dose adjustment calculator to obtain a new dosage regime. Consider omitting dose based on the level: – If vancomycin trough level is 20-25mg/L, give new dosage regime without omitting any doses. Take a level before the 4th new dose.
Why are Vanco troughs drawn?
Vancomycin blood levels are drawn at timed intervals to measure drug levels during treatment. Vancomycin has a narrow therapeutic index, which is the ratio between the toxic and effective dose of medication.
When do you draw vancomycin trough after hemodialysis?
How long should you wait? Generally, most people wait 4-6 hours after the end of dialysis before checking post-HD vancomycin levels to avoid falsely low results.
How do you draw a peak and trough?
To assess drug concentrations during the trough phase, blood should be drawn immediately before the next dose. To assess peak levels, the time for drawing depends on the route of administration: Oral: One hour after drug is taken (assumes a half-life of > two hours) IV: 15-30 minutes after injection/infusion.
When is a vancomycin trough used in pediatrics?
Vancomycin troughs are recommended to be drawn within 1 hour prior to next dose. Vancomycin peak levels are not routinely recommended because of lack of correlation to efficacy. In general, a trough concentration of 10-15 mcg/mL is desired.
Do you refrigerate Vanco trough?
Refrigerated (preferred) or frozen. Specimen stability: Room temperature: 48 hours.
Does a Vanco trough need to be spun?
Container/Tube: EDTA plasma (lavender top tube). Collection Instructions: Draw blood just prior to next dose. Spin down within 4 hours of draw.
What color tube does Vanco trough go in?
MUST be collected in a red top tube NO GEL; For the Vancomycin, Total, 2 specimens are required, 1 peak specimen and 1 trough specimen.
How do you dilute vancomycin for oral?
The dose of vancomycin administered orally can be diluted in 30 ml of water and given to the patient, or administered by nasogastric tube.
How do you take vancomycin 4 times a day?
Take the capsules exactly as your doctor tells you to. It is usual to take one (125 mg) capsule four times a day for 10-14 days. In serious infections, the dose could be as high as 500 mg four times a day for 10-14 days.
How fast should Vancomycin be infused?
Vancomycin should be infused slowly in a dilute solution (2.5 to 5.0 mg/ml) at a rate no greater than 10 mg/min and over a period not less than 60 minutes to avoid rapid infusion-related reactions. Stopping the infusion usually results in a prompt cessation of these reactions.
Is it OK to drink alcohol while taking vancomycin?
Official Answer. Alcohol will not diminish the effectiveness of Vancomycin. However alcohol can cause similar side effects, such as stomach upset, dizziness and drowsiness and when you combine the two these side effects may increase. Alcohol can also reduce your energy and delay how quickly you recover from illness.
How do you monitor gentamicin levels?
Pre-dose (trough) gentamicin levels should be checked after 24 hours and then twice weekly (target <1mg/L). Peak gentamicin levels, taken one hour after administration, can also be measured (target 3–5mg/L). Individualised dosing based on the patient’s pharmacokinetics can also be used.
When and how should vancomycin be administered in a patient undergoing dialysis?
Conclusion: Administration of vancomycin during the last hour of dialysis session is safe, efficacious with regards to infection control, achieved recommended vancomycin concentrations despite the use of high-flux membranes, and improved patients’ quality of life.
Does isolated ultrafiltration remove vancomycin?
One can remove fairly large amounts of vancomycin with long high-flux dialysis treatments along with substantial ultrafiltration. In one study, the authors were able to lower the serum vancomycin level of one patient from 99ng/mL to 36ng/mL with three long hemodiafiltration treatments using high-flux dialyzers [6].
When do you Redose vancomycin in peritoneal dialysis?
The ISPD Guidelines for the treatment of peritoneal dialysis-associated infections recommend that vancomycin should be administered in a dose of 15 – 30 mg/kg IP with further doses repeated every 5 – 7 days in continuous ambulatory PD or 3 – days in APD with the aim of maintaining trough serum vancomycin levels above.
Which is drawn first peak or trough?
A trough level is drawn immediately before the next dose of the drug is administered. A peak level is drawn 1 to several hours after the drug is administered (depending on the drug).
What is difference between peak and trough?
The trough level is the lowest concentration in the patient’s bloodstream, therefore, the specimen should be collected just prior to administration of the drug. The peak level is the highest concentration of a drug in the patient’s bloodstream.
When do you draw a phenytoin trough?
In these situations of routine monitoring (unlike the emergency situation of breakthrough seizures in scenario two), it is preferable to draw the phenytoin level just prior to the next dose (a trough level) or at least eight hours after the last dose10,11.
When is vancomycin at steady state?
Collect sample for steady state vancomycin level approximately 18-30 hours after the start of the infusion (with routine bloods where possible). If the steady state level is within target range, continue vancomycin infusion and repeat steady state level 18–30 hours after the first level.
What serum trough level is appropriate for pediatric patients with renal dysfunction?
A gentamicin trough level should be obtained within 1 hour of the dose: Obtain level prior to the administration of the 2nd dose. If impaired renal function is a concern, a level should be obtained before the 2nd dose. An acceptable trough is < 2 mg/mL, with an optimal target ≤ 1.0.
What nursing considerations are essential when giving vancomycin?
Some considerations for nurses administering vancomycin include ensuring a patent IV line, planning for administration of the preoperative dose as much as two hours before the initial incision is made, and including information about the dose and timing of preoperative vancomycin administration in the surgical time out.
