How do you taper NTG infusion?
Discontinue as per doctors instructions Increase to a maximum of 12 mls per hour in increments of 0.3 – 0.6 mls per hour at approx 30 minute intervals. Increase GTN only in steps of 0.3 ml – 0.6 ml per hour at approx 30 minute intervals. Check BP every 15 minutes on drug increase. Maintain 90 mmHg systolic BP.
How is nitroglycerin titration calculated?
The calculation for the origi- nal infusion of 10 mcg/minute is 10 x 0.3 = 3 ml/hour. You’d calculate the titrations like this: 5 x 0.3 = 1.5 ml/hour (5 mcg/minute) 15 x 0.3 = 4.5 ml/hour (15 mcg/minute) 20 x 0.3 = 6 ml/hour (20 mcg/minute) …and so on.
What special considerations must be made for IV nitroglycerin?
For nitroglycerin, the following should be considered:
- Allergies. Tell your doctor if you have ever had any unusual or allergic reaction to nitroglycerin or any other medicines.
- Pediatric.
- Geriatric.
- Breastfeeding.
- Interactions with medicines.
- Interactions with food/tobacco/alcohol.
- Other medical problems.
When do you give nitroglycerin IV?
Nitroglycerin injection is used to treat hypertension (high blood pressure) during surgery or to control congestive heart failure in patients who have had a heart attack. It may also be used to produce hypotension (low blood pressure) during surgery.
How long is nitroglycerin IV stable?
The concentration of NTG in the i.v. solutions was determined spectrophotometrically. Nitroglycerin was found to be stable for at least 70 days when stored in glass containers, regardless of source, diluent (5% dextrose in water or normal saline) and storage temperature.
How do you administer nitroglycerin?
- Adults—1 tablet placed under the tongue or between the cheek and gum at the first sign of an angina attack. 1 tablet may be used every 5 minutes as needed, for up to 15 minutes. Do not take more than 3 tablets in 15 minutes.
- Children—Use and dose must be determined by your doctor.
How do you titrate GTN?
To obtain an admixture of Glyceryl Trinitrate at a concentration of 100 micrograms/ml, add 50 ml Glyceryl Trinitrate solution (containing 50 mg glyceryl trinitrate) to 450 ml of infusion vehicle to give a final volume of 500 ml. A dosage of 100 micrograms/min. can be obtained by giving 60 ml of the admixture per hour.
What titration means?
titration, process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion.
How do you titrate off nitroglycerin drip?
If systolic BP falls below 90 mmHg during titration, decrease the drip rate by 10 mcg/min and give a NS IV/IO fluid bolus up to 1 liter, wide open. If BP remains below 90 mmHg, discontinue drip.
How do you administer nitroglycerin IV?
Initially, 5 to 10 mcg/minute continuous IV infusion. Titrate by 5 mcg/minute IV every 3 to 5 minutes until clinical response, or to a dose of 20 mcg/minute IV.
What is nitroglycerin IV?
Descriptions. Nitroglycerin injection is used to treat hypertension (high blood pressure) during surgery or to control congestive heart failure in patients who have had a heart attack. It may also be used to produce hypotension (low blood pressure) during surgery.
How often do you titrate nitroglycerin IV?
Nitroglycerin (NTG) Intravenous Drip: Begin at 5 mcg/min and titrate every 3-5 minutes to therapeutic response and stable vital signs. Titrate NTG infusion until relief of chest pain or maximum of 200 mcg/min dose is achieved.
How is nitroglycerin (NTG) administered?
NTG is administered via IV pump in separate IV access line using vented IV nitroglycerin tubing. IV NTG is supplied in glass bottles at 200 micrograms/ml. Contraindications
What is the appropriate dose of nitroglycerin for pre-hospital use?
B. For pre-hospital use, begin the nitroglycerin drip at 10 mcg/min and increase by 10 mcg/min at 5 minute intervals if chest pain persists and systolic blood pressure remains above 100 mmHg.
How do you titrate NTG infusion?
Intravenous Drip: Begin at 5 mcg/min and titrate every 3-5 minutes to therapeutic response and stable vital signs. Titrate NTG infusion until relief of chest pain or maximum of 200 mcg/min dose is achieved. Topical: Transdermal patch q 24 hours for 10-12 hour duration (with at least 12 hours NTG free out of each 24 hour period)
