gynecology and nitrous oxide

The gynaecology

Statistics from the German Medical Association from 2020 show that a total of 19151 doctors in Germany specialise in gynaecology and obstetrics. (

Gynaecology deals with both the internal and external female reproductive organs. Gynaecology is also concerned with the detection, treatment and prevention of diseases of the female sexual and reproductive tract.

Nitrous oxide sedation in gynaecology

Nitrous oxide is a non-irritating, non-allergenic gas that acts directly on the central nervous system and has a relaxing, anxiety-relieving effect. Within a few breaths, patients can feel the calming effect of the gas and release their fears, worries and discomfort. Nitrous oxide (Nitrous oxide) acts directly on the central nervous system, but has no effect on the patient's natural protective reflexes, breathing or consciousness. In this article you will learn how all these positive factors of the sedative can be advantages for interventions in gynaecology.

The administration of nitrous oxide

The administration of nitrous oxide

The nitrous oxide-oxygen mixture is administered via a soft, cuddly Baldus disposable double nasal mask, according to the needs of the respective patient. Initially, pure oxygen flows through the comfortable nasal mask while the attending physician slowly increases the amount of nitrous oxide until the patient is perfectly sedated. A previously applied pulse oximeter gives the doctor information about the patient's condition at any time. In addition to this, the patient is able to give feedback to the doctor about his or her well-being at any time, since consciousness is not affected during a Sedation with nitrous oxide is completely preserved.

As soon as an optimal Sedation is achieved, the amount of nitrous oxide is maintained for the duration of the treatment, after which the patient breathes pure oxygen for a few minutes to slowly eliminate the sedation. After this recovery phase the nitrous oxide has completely left the body, the patient does not have to expect any after-effects and can leave the practice without discomfort and without an escort.

When is nitrous oxide used in gynaecology?

Nitrous oxide sedation can be used in gynaecology to make treatment as comfortable as possible for particularly anxious or pain-sensitive patients and to make the work of the doctor treating them easier. One example of a suitable application of nitrous oxide sedation is the use of intrauterine systems such as IUDs and copper chains. Patients can relax completely during the procedure, are distracted as they concentrate on their breathing and release their anxiety. The doctor can therefore look forward to a relaxed patient and a simple procedure without interruptions due to pain. Both sides can look forward to the appointment with different eyes. Nitrous oxide sedation can also be interesting for upcoming preventive appointments or the treatment of tumours.

Indications and contraindications


Before sedation with laughing gas, the question naturally arises for which patients the method is particularly suitable. Laughing gas is suitable for a large patient base thanks to its many positive properties and the low number of risks.

Indications include:

  • Particularly anxious patients
  • Pain sensitive patients
  • Mental or physical disabilities
  • Stress prevention in mild cardiac problems and asthma
  • patients in which one anesthesia is contraindicated
  • Longer or complex surgical treatments


Before a nitrous oxide sedation, the few possible contraindications of nitrous oxide should be discussed with the attending doctor in order to exclude risks and side effects during the treatment. The contraindications include, among others:

  • Otitis media
  • Drug abuse
  • Impaired or restricted nasal breathing
  • ...

A possible contraindication that we would like to point out here is pregnancy in the 1st - 3rd trimester. For detailed information on the possible risks involved, patients interested in laughing gas sedation should always discuss this with the doctor treating them.

During childbirth, however, nitrous oxide can be used without hesitation to offer women an alternative to epidural anaesthesia (epidural anaesthesia), which also significantly reduces the sensation of pain. The use of nitrous oxide during childbirth creates a feel-good atmosphere in which women can release their fears and relax. You can find more information on the use of nitrous oxide sedation during childbirth in our Blog post.

Further comprehensive information on the indications and contraindications of laughing gas sedation can be found in our Blog post or through personal consultation by one of our experts.

Integrating nitrous oxide into your own practice

Now you may be wondering how much effort is involved in implementing nitrous oxide sedation in your practice and daily practice routine. A few products are needed for the administration of nitrous oxide, which we would like to list for you here first:

In addition to the products, a certification for the application of nitrous oxide is necessary, which you can easily and conveniently obtain through one of our nationwide certification courses. In our Blog post, as well as on our Homepage you will find a lot of information about our certification courses.

This may seem like a lot at first glance. But if you take a closer look at our nitrous oxide mixers, you will notice that they can be easily integrated into the practice. The mixers are modern, mobile, space-saving and can be individually designed. The other products listed above are also connected directly to the mixer and do not take up any more space.

The time required for the preparation and follow-up of the laughing gas sedation is also really small.

The following measures serve as preparation:

  • Patient information on laughing gas sedation (here our flyers are a good aid and save you a lot of effort)
  • Selection of the fragrance mask
  • Setting the Total flow According to the patient
  • Creating the mask
  • Putting on the pulse oximeter

Follow-up includes:

  • Discharge of laughing gas sedation through 5-minute supply of pure oxygen
  • Removing the mask
  • Removing the pulse oximeter
  • Enquire about patient condition
  • Patient documentation for sedation (takes place at the Baldus Touch fully automatic)

You can obtain complete information about the procedure of laughing gas sedation in our E-learning and the Certification courses of our n2o academy.

You can also find us on Facebook and Instagram. Many interesting videos on laughing gas sedation can be found on our YouTube channel. If you have any questions, please use the contact form on our website, or the Baldus Expert Chat here on
