Halothane - Benefits, dosage and side effects

Halothane is a gaseous anesthetic used to calm and desensitize the patient during the surgical procedure. Halothane should only be given by a doctor or medical officer under the supervision of a doctor in a hospital.

Halothane works by decreasing the work of the central nervous system which will affect breathing and heart contractility. This mode of action is used to induce (start) and maintain the anesthetic process before and during surgery.

Dosage and Instructions for Use of Halothane

The dose of halothane given depends on the patient's condition and the medical procedure to be performed. The dose given can be in the form of percent volume / volume (% v/v).

Halothane can be administered with a mixture of oxygen or nitrous oxide. Here are common halothane doses:

  • Mature: 0.5% v/v. The dose can be increased up to 2–4% v/v. The dose to maintain anesthesia is 0.5–2% v/v.
  • Children: 1.5–2% v/v. The dose to maintain anesthesia is 0.5–1% v/v.

How to Use Halothane Correctly
