1. What is the medicine and what is it used for
is a gas with analgesic and anesthetic effects. It is not metabolized in the body and is excreted unchanged in exhaled air - for use only in closed healthcare facilities.
To induce and maintain general anesthesia in combination with other anesthetics (inhalation or intravenous).
In a mixture with oxygen to achieve an analgesic effect caused by shallow anesthesia without loss of consciousness (e.g., dressing changes, diagnostic tests, obstetric analgesia).
2. Important information before using the medicine
When not to use the medicine:
- nitrous oxide should not be administered without the addition of oxygen and in a breathing mixture containing less than 30% oxygen. The administration time in a mixture with oxygen should not exceed 12 hours,
- if the patient is allergic to the active substance or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before starting treatment, you should discuss it with your doctor.
If the patient has or has had a problem with substance abuse/psychoactive drugs, the risk of dependence on nitrous oxide is higher in the case of repeated use. The doctor will decide whether it can be used in such a case.
Caution should be exercised in the case of hypovolemia, shock, heart disease - possibility of severe hypotension.
Repeated or prolonged use of nitrous oxide may increase the risk of vitamin B deficiency, which can lead to bone marrow or nervous system damage.
The doctor may order a blood test before and after using nitrous oxide to assess the effects of possible vitamin B deficiency.
Medicine interactions
Used together with medicines that have a depressive effect on the central nervous system, respiratory system, or cause hypotension, may enhance their effect. Used in combination with high doses of Fentanyl (and its derivatives) may cause a decrease in heart rate and cardiac output. These symptoms may occur especially in patients with left ventricular heart failure.
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, suspects that she may be pregnant, or plans to have a child, she should consult a doctor before using this medicine.
Animal studies have shown a potential risk of fetal death, growth disorders, and bone development disorders after prolonged use of nitrous oxide.
Driving and using machines
Impairs the ability to drive vehicles or operate machinery.
3. How to use the medicine
Only as directed by a doctor. Nitrous oxide is administered in a mixture with oxygen and possibly with other inhalation or intravenous anesthetics, using special calibrated inhalation devices or anesthesia equipment. It is usually dosed through a flow meter with measurement in liters per minute. It is usually used in a mixture with oxygen in a volume ratio of 70% nitrous oxide and 30% oxygen for maintaining anesthesia or in a ratio of 50% nitrous oxide and 50% oxygen to induce short-term analgesia.
Stopping the medicine
The only symptom may be signs of hypoxia when nitrous oxide administration is stopped and atmospheric air breathing is started. Due to the sudden cessation of nitrous oxide inhalation, there is a release of nitrous oxide from tissues, an increase in its volume in lung alveoli, which leads to a dilution of oxygen in the air. As a precaution, the nitrous oxide supply should be turned off in advance and the patient should be ventilated with pure oxygen to remove nitrous oxide from the tissues.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Nitrous oxide used in general anesthesia does not cause any side effects. After surgical procedures, nausea and vomiting may occur. During prolonged use, leukopenia or thrombocytopenia and megaloblastic anemia (especially in cases of vitamin B deficiency) may occur, which disappear after returning to breathing air. Due to easy penetration into closed spaces, it may increase their volume or pressure (middle ear, paranasal sinuses, inflated intestinal loops, pneumothorax).
Generalized seizures of unknown frequency.
Of unknown frequency (frequency cannot be determined based on available data)
- Dependence
- Symptoms from the nervous system, feeling of numbness and weakness, usually in the legs.
