amid the situation of slotxo the COVID-19 outbreak that is becoming more and more intense every day like this Inventing new ways to save lives of patients with respiratory failure is critical. Recently, a team of Japanese researchers found that Bringing oxygen into the blood through a peculiar channel like the anus. It can save the lives of some animals, such as pigs and rats, whose body structure is similar to that of humans.
Such an approach, which may be called "breathing breech" is considered as an alternative to saving the life of people with hypoxia. but cannot use a ventilator or artificial lung to treat Because that person was in a situation where medical equipment was scarce. Or the combined ventilator and anesthesia can damage delicate lung tissue.
Dr. Takanori Takebe, a research team leader at the Tokyo University of Medicine and Dentistry (TMDU), revealed that the idea of ​​introducing oxygen through the intestines from some freshwater fish. which such fish can live with this strange breathing
Initially, a small ventilator was surgically inserted into the anus of the rats. But this method requires scrubbing the intestinal wall to remove the mucus coating first. Oxygen is able to penetrate through the intestinal wall into the bloodstream. This extreme method gave the rats a very low survival rate.
The research team then turned to an experimental approach, in which an oxygen-saturated liquid "perfluorocarbon" (PFC) was introduced into the rectum. This is because the substance was previously used to treat babies' lungs. and has been used in experiments to allow humans to breathe with liquids. without being toxic or dangerous in any way
This time, four pigs were put on a ventilator. to adjust them to have a lower breathing rate than normal After that, two pig anus enema was tested with concentrated oxygen-containing PFC. by changing the aforementioned fluid every hour
The results showed that pigs undergoing an enema had higher levels of oxygen in the blood after every time PFC was introduced into the intestines. also have higher levels of oxygen in the body The skins of the four pigs were noticeably warmer and more rosy.
As for the rats in the closed box, the air breathed lightly. to have a higher oxygen level in the body run longer and more oxygen enters the heart when receiving an enema with the said PFC
However, more years of experimental studies will be needed. To confirm whether this method is effective and safe for humans or not. especially in critically ill patients with abnormal bowel function
