1. What is MEDICINAL NITROUS OXIDE LINDE and what is it used for
Nitrous oxide is an inhalation gas that belongs to the group of general anesthetics (nervous system and central).
This medication is for hospital use only.
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 starting to use MEDICINAL NITROUS OXIDE LINDE
Nitrous oxide is a combustible gas that allows and accelerates combustion.
Do not use MEDICINAL NITROUS OXIDE LINDE:
Inhalation of nitrous oxide can cause gas bubbles and gases trapped in body cavities can expand due to increased diffusion of nitrous oxide. Therefore, do not use nitrous oxide:
- If you need ventilation with pure oxygen.
- In patients with intraocular gas injection (e.g., SF6 or C3F8).
- If you have pneumothorax (air in the pleural cavity), emphysema (bronchial obstruction), or have air in the pericardium (membrane surrounding the heart) due to injury or disease, e.g., due to smoking, air, or gas bubbles in the body.
- Do not use it for more than 24 hours consecutively.
- If you have recently engaged in diving activities and may be at risk of decompression sickness.
- If you have recently undergone cardiopulmonary bypass.
- If you have abdominal gas distension
- If you have severe heart failure (e.g., after cardiac surgery), as nitrous oxide could increase cardiac dysfunction.
- If you have persistent signs of confusion, altered cognitive function, or other signs that may be related to increased intracranial pressure, as nitrous oxide could increase intracranial pressure.
- If you have decreased level of consciousness or ability to collaborate and follow instructions, as nitrous oxide could decrease protective reflexes.
- If you have a diagnosed deficiency of folic acid or vitamin B12, untreated, or have genetic alterations in the enzymatic system related to vitamin metabolism, as the use of nitrous oxide could increase this deficiency.
Be careful with MEDICINAL NITROUS OXIDE LINDE:
Also, inform your doctor if you have or present any of the following symptoms/signs:
- If you have intestinal obstruction or heart failure.
- If you suffer from vitamin B12 deficiency.
Ear discomfort, such as ear inflammation, as nitrous oxide could increase middle ear pressure.
- If you have a history of drug abuse, as there is a high risk of dependence on nitrous oxide if taken repeatedly. Your doctor will decide when MEDICINAL NITROUS OXIDE LINDE is possible in your case.
Prolonged or repeated use of nitrous oxide can increase the risk of vitamin B12 deficiency, which can lead to damage to the bone marrow or nervous system. Your doctor may require blood tests before and after treatment to evaluate the consequences of a possible vitamin B12 deficiency.
Using MEDICINAL NITROUS OXIDE LINDE with other medications
MEDICINAL NITROUS OXIDE LINDE potentiates the hypnotic effects of intravenous or inhaled anesthetics (thiopental, benzodiazepines, morphine, halogenated), so the dosage of these should be reduced.
Inform your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription.
If you are taking other medications that affect the brain or brain function, such as benzodiazepines (tranquilizers) or morphine, you should inform your doctor. Nitrous oxide can increase the effects of these medications. Nitrous oxide, taken together with other sedatives or medications that affect the central nervous system, increases the risk of side effects.
You should also inform your doctor if you are taking medications with methotrexate (e.g., for rheumatoid arthritis), as nitrous oxide increases the side effects of these medications.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or nurse before using this medication.
Pregnancy
During pregnancy, it is recommended not to exceed a concentration of 50% of MEDICINAL NITROUS OXIDE LINDE in the inhaled mixture.
- Obstetric anesthesia:
Due to the rapid transfer across the placental barrier, it is recommended to interrupt the administration of MEDICINAL NITROUS OXIDE LINDE if the time between induction of anesthesia and fetal extraction exceeds 20 minutes. Avoid using MEDICINAL NITROUS OXIDE LINDE in case of fetal distress.
- Obstetric analgesia:
The use of MEDICINAL NITROUS OXIDE LINDE for this indication can only be performed if a safety flowmeter is available to prevent the administration of MEDICINAL NITROUS OXIDE LINDE at a concentration greater than 50%.
Breastfeeding
Consult your doctor before using this medication.
Driving and using machines
It is recommended not to drive vehicles and not to use machines for 24 hours after anesthesia with MEDICINAL NITROUS OXIDE LINDE.
3. How to use MEDICINAL NITROUS OXIDE LINDE
Your doctor will determine the correct dose of MEDICINAL NITROUS OXIDE LINDE and it will be administered through a system suitable for your needs, ensuring the supply of the correct amount of oxygen.
During treatment with nitrous oxide, you and the administration of this medication must be monitored to ensure that the nitrous oxide is administered safely. After completing the administration, you should be monitored by healthcare personnel until you have recovered.
Nitrous oxide is normally administered in a gas mixture containing at least 21% oxygen to avoid the risk of hypoxia (oxygen deficiency). Nitrous oxide is normally used at doses between 50 and 70% of the inhaled gas volume.
If you use more MEDICINAL NITROUS OXIDE LINDE than you should
There is a risk of cyanosis and hypoxia. The administration of MEDICINAL NITROUS OXIDE LINDE should be interrupted and the patient ventilated (air or oxygen).
