Here, you will find medications for pediatric anesthesia and pediatric intensive care. There is a medication calculator to quickly find the correct dosages of the drugs commonly used in pediatric anesthesia. Dosages for parenteral medications for children, such as antibiotics and analgesics, are also provided.

Dexmedetomidine


Provides good premedication for small children coming in for ear, nose, and throat procedures. Dexmedetomidine injection solution (Dexdor®) 100 µg/ml can be administered both nasally and buccally. Nasal administration is preferred as it gives better absorption and quicker effect. The solution has no taste and does not sting in the nose. Dexmedetomidine is a specific alpha2 receptor agonist and its effect is similar to clonidine but with a more pronounced effect. The main effects are sedation and some analgesia. Dexmedetomidine has a shorter half-life, about 2 hours compared to clonidine’s 5-10 hours. The onset time is significantly longer compared to orally administered Midazolam, about 20-40 minutes.

Concentrate for infusion solution 100 µg/mL is used for NASAL use.

Nasally: Approximately 30 minutes before the procedure. Sedation usually occurs within 10-15 minutes, with maximum effect after 30 minutes. For deep sedation, the child should urinate before administration. If necessary, remove superficial secretions from both nostrils before administration. To adjust the dosage according to the patient’s weight, a Mucosal Atomization Device (MAD) is used. MAD is a single-use tip with a spray function that attaches to a 1 mL syringe.

HALF of the total dose should be administered in each nostril. The volume per nostril should be 0.1 – 0.2 mL (for children under 15 kg, a volume of 0.1 mL is suitable). This is to avoid the medicine running down the throat and not providing the desired effect. If the dosing volume is larger, the dose needs to be divided into multiple sprays. 0.1 – 0.2 mL is given in each nostril with at least 30 seconds up to 2 minutes between each spray. MAD must be pre-filled with dexmedetomidine (about 0.1 mL) before the first spray, this is to ensure the correct dose is administered. The syringe should not be filled with air behind the liquid, as the patient would receive too high a dose due to both the pre-fill and the volume in the syringe tip being sprayed out. Tilt the child’s head back and aim the syringe and adapter outward toward the nasal wings to optimize absorption. Push the plunger quickly and firmly so that the liquid is released as an aerosol. The same MAD can be used for any remaining sprays to the same patient. In these cases, pre-filling is not necessary. Remember to pre-fill each MAD before the first spray or if changing MAD between sprays.

COMMON INDICATION AND DOSE

Several cases of bradycardia (even) in the late stage have been reported.

Monitoring

Oxygen saturation, pulse, and blood pressure should be checked before administration and after the procedure is completed. During the procedure, the child should be under observation. For moderate to deep sedation: Continuous monitoring of oxygen saturation and pulse. For total doses from 3 µg/kg: Continuous monitoring of oxygen saturation and pulse as well as continuous monitoring with ECG. Additional monitoring/actions may be required, especially in combination with other drugs. Follow local guidelines.

Max dose Usually no more than 100 µg/DOSE (divided into multiple sprays). The effect of the given dose depends on the spray technique. A suitable max dose is determined by a reasonable volume for nasal administration and the child’s age.

Reasonable dose for dexmedetomidine nasal 100 microg/ml

  1 kg 5 kg 10 kg 50 kg
1 mikrog/kg --0,1 mL 0,5 mL
2 mikrog/kg - 0,1 mL 0,2 mL 1 mL
3 mikrog/kg - 0,15 mL 0,3 mL 1,5 mL

Light sedation before procedure, e.g., insertion of PVK

Children 1 month – 18 years: Usual dose 1 – 2 µg/kg.
The dose can be repeated after 30 minutes if needed.

Moderate sedation before procedure, e.g., during LP

Children 1 month – 18 years: Usual dose 1 – 3 µg/kg.
The dose can be repeated after 30 minutes if needed.

Deep sedation before procedure, e.g., during MRI

Prescribed by a doctor with anesthesia or intensive care competence, or equivalent.
Children 1 – 5 months: Loading dose 2 µg/kg.
If needed, an additional 1 µ g/kg can be given. Max 3 µg/kg.
Children 6 months – 18 years: Loading dose 3 – (4) µg/kg.
If needed, an additional 1 – (2) µg/kg can be given. Max 5 µg/kg.

Deep sedation before procedure, e.g., during MRI – for NEWBORNS

Very limited experience with use in newborns. Should only be prescribed in exceptional cases. Continuous monitoring with ECG, oxygen saturation, and pulse is required. Newborns (premature): Individual dosing, usually requires significantly lower doses than those listed below.
Newborns (full-term with birth weight over 3 kg): Loading dose 2 µg/kg. If
needed, an additional 1 (- 2) µg/kg can be given.

Premedication with Intranasal Sufentanil for Children


Indication

Children undergoing anesthesia where sedation is considered appropriate before induction.

Contraindication

Ongoing nosebleed or other nasal obstruction.

Administration of intranasal sufentanil requires the presence of anesthesia personnel, continuous monitoring capability, and possibly ventilation support.

Effect

Sedation is usually achieved within 10 – 15 minutes, and maximum analgesic effect occurs after 20 – 25 minutes. In some patients, the effect may occur within a few minutes.

Dosage/Administration

  • Sufentanil 1 microgram/kg (50 micrograms/ml) is administered with a 2 ml syringe connected to a Mucosal Aerosol Device (MAD). Use a Luer Lock syringe to prevent the MAD from detaching during injection.
  • Total dose 1 – 2 micrograms/kg: Half the dose is administered in each nostril.
  • Administer one syringe with 0.1 – 0.2 ml at a time. During application, aim upwards inside the nostril towards the eyes (in the cranial direction).
  • Apply in both nostrils as quickly as possible. It is important to use force on the plunger to achieve aerosolization.
  • Uncertain effect with larger volume, as part of the dose passes by the nasal mucosa and is swallowed.
