Rectal administration pathway for transport of compounds systemically have been administered since before recorded history, using instruments ranging from cow horns and hollowed out bamboo shoots to metal syringes to inject laxatives, herbs, opium, turpentine, tobacco, oxygen and noxious chemicals. The word ‘enema’ is said to have come from a Greek word meaning ‘I throw it in’, but in fact until the late eighteenth century the preferred word was not enema but ‘clysters’.
Clysters were used in ancient India where they are listed in the two main texts on treatments, Caraka-Sambita and Susruta-Sambita5 and in both Mesopotamia and Egypt where it was recommended that they be used monthly. In Egypt, health was thought to depend on regular cleaning out of the rectum which was associated with residual decaying material which, if not washed out, could enter the bloodstream and cause illness. It is in Egyptian papyri, in particular Eber’s (c. 1500 BC), that mention is first made of using the rectum to give medications.
In 1888, a Dr Kellogg of Battle Creek Sanatorium, USA, reported on what he claimed was the first oxygen enema, explaining that the gas could be absorbed through the rectal mucosa in cases of hypoxia, his theory being based on the gaseous exchange he claimed takes place in the alimentary canals of certain fishes.
Rectal administration route
Rectal administration uses the rectum as a route of administration for medication and other fluids, which are absorbed by the rectum's blood vessels, and flow into the body's circulatory system, which distributes the ozonides systemically.
The rectal route bypasses around two thirds of the first-pass metabolism as the rectum's venous drainage is two thirds systemic (middle and inferior rectal vein) and one third hepatic portal system (superior rectal vein). This means medication will reach the circulatory system with significantly less alteration and in greater concentrations.
Finally, rectal administration can allow people to remain in the home setting when the oral route is compromised. Unlike intravenous lines, which usually need to be placed in an inpatient environment and require special formulation of sterile medications, a rectal catheter can be placed in the rectum in the home.
Nitrogen - Chemical Formula (N)
Rectal insufflations are classed as Non-clinical Applications, however, the oxygen purity for
systemic applications such as rectal insufflations should be of high purity. Oxygen
concentrators are not recommended for such applications, due to the few percent of nitrogen present. Oxygen concentrators use Pressure Swing Adsorption (PSA).
This system operates on a similar principle to the heat less desiccant dryer in that air is pressure fed to a molecular sieve. The selected media will be pressurized to then adsorb nitrogen, moisture, hydrocarbons, and CO2, leaving oxygen to flow through. When the pressure is reduced, the vapor, nitrogen, and other gases are dispersed and removed by the purged gas. The product gas contains about 90-95% O2 and a few percent each of nitrogen and argon.
Nitrogen is not a metabolic gas and isn't either produced or consumed in the body, its partial pressure is very high. No compound of blood can react with Nitrogen hence its diffusion is not possible though the lungs. O2 and CO2 are the important gasses for biological function and oxygen is very soluble though venous blood (mitochondria). Nitrogen gas is the primary cause of an air embolism, and although relatively an insoluble gas, this should not mean that its solubility should not be a consideration for systemic applications.
Bio-availability though Humidification of ozone gas
Must you humidify ozone before performing an insufflation?
Humidification of ozone gas is a process whereby ozone gas is infused though an inorganic liquid before administration. This subject is very controversial as such a claim contradicts the laws of chemical and non-chemical absorption. The Ozone Therapists I’ve consulted with over the years all contradicted each other to one degree or another. Some ozone specialists state that once ozone gas has been infused though a liquid, the gas has combined with a H20 water molecules in the process and thus creates better absorption for insufflations. I will explain why this perception contradicts the laws of absorption and exothermic reactions.
