1. What is NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH and what is it used for
Nitrous oxide is a cryogenic gas for inhalation. Treatment with nitrous oxide is indicated in the following cases:
- As an adjunct to general anesthesia, in combination with all anesthetic agents administered intravenously or by inhalation.
- As an adjunct to analgesia in the operating room or delivery room.
2. What you need to know before using NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH
Do not use NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH.
- If you need ventilation with pure oxygen.
- If there is a possibility of air or gas accumulation in the body. This may apply to cases of untreated pneumothorax ("lung collapse"), pulmonary bullous emphysema, or decompression sickness ("decompression syndrome").
- Do not use it for more than 24 hours in a row.
- If you regularly or constantly inhale medicinal oxygen.
- If a sudden obstruction occurs in the gastrointestinal system.
- If there is a possibility of increased intracranial pressure, characterized by sudden headache, blurred vision, increased cerebrospinal fluid pressure, signs of neurological loss, and loss of consciousness.
- If there are facial injuries in the area where the anesthesia mask is placed.
- After an injection of gas (e.g., SF6, C3F8) into the eye, it may cause an increase in eye volume and the possibility of causing blindness (the doctor should not use nitrous oxide medicinal until sufficient time has passed).
- If there is a vitamin B12 deficiency in the early stages of pregnancy.
Warnings and Precautions
- If you have heart failure, monitor your blood pressure to avoid a drop.
- If you are going to undergo ear surgery and adjacent air-filled spaces.
- If you have a vitamin B12 deficiency, as occurs in people with pernicious anemia (malignant form of anemia) or Crohn's disease (chronic enteric disease) or in vegetarians.
- If you have sickle cell anemia (a specific blood disease in which red blood cells have an abnormal shape).
- If you have received analgesia containing opium during delivery (the combination of this type of medication with nitrous oxide medicinal may cause loss of consciousness).
- After an injection into the eye (with another agent), sufficient time must pass before administering nitrous oxide medicinal, as otherwise, there is a risk of eye problems (including blindness).
- When benzodiazepines are administered at the same time (a specific group of medications with tranquilizing, soporific, and/or muscle relaxant properties), as loss of consciousness may occur.
- If you have received treatment with bleomycin (a medication administered in cancer treatment).
Please consult your doctor if you have or have had any of these situations.
Using NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH with other medications
Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medication.
- It should be considered that nitrous oxide potentiates the hypnotic effects of intravenous or inhaled anesthetics (thiopental, benzodiazepines, morphine, halogenated). This allows for a reduction in doses.
- The action of certain muscle relaxants (such as pancuronium, vecuronium) increases the effect of nitrous oxide medicinal.
- The damage caused by sodium nitroprusside (a medication used to treat high blood pressure) and methotrexate (a medication used to treat cancer) increases because the action of vitamin B12 is neutralized by nitrous oxide medicinal.
- The damage caused by bleomycin (a medication used to treat cancer) in the lungs may increase if oxygen administration is increased (as occurs in treatment with nitrous oxide medicinal).
Pregnancy, Breastfeeding, and Fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
It is recommended not to exceed a concentration of 50% nitrous oxide in the inhaled mixture.
Pregnancy
Some data have indicated that short-term use of nitrous oxide during pregnancy does not pose a greater risk of congenital malformations. In isolated cases, nitrous oxide may cause respiratory problems
Breastfeeding
It is unknown whether nitrous oxide medicinal is excreted in breast milk. It is not necessary to interrupt breastfeeding after a short period of administration.
Driving and Using Machines
Do not drive vehicles or operate machinery within 24 hours after anesthesia in which nitrous oxide was used.
3. How to use NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH
For inhalation use.
This medication will be administered by a doctor and the correct dose will be established.
The doctor will determine the correct dose of NITROUS OXIDE MEDICINAL and administer it through a system suitable for your needs (for short-term use in pain relief or in combination with anesthetic medications) that ensures the supply of the correct amount of oxygen.
When used for pain relief, it should be used in combination with oxygen in the same proportion (50% nitrous oxide and 50% oxygen).
Nitrous oxide requires use in combination with oxygen so that the oxygen concentration is always equal to or greater than 21% and a device with an anti-backflow valve and an alarm system in case of oxygen supply failure is used.
If you use more NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH than you should:
Nitrous oxide administration will be interrupted and you will be ventilated with air or oxygen.
If you stop treatment with NITROUS OXIDE MEDICINAL LIQUID OXYGEN HEALTH
If you stop using nitrous oxide medicinal and oxygen medicinal, you may experience oxygen deficiency. To avoid this, you can temporarily be ventilated with 100% oxygen.
If you have any other questions about the use of this product, ask your doctor or pharmacist.
