CYCLOPROPANE (Cyclopropanum).

     Synonym: Cyclopropane.

     Beztsvetny fuel gas with a characteristic smell, like the smell petroleynogo ether, sodium taste. The relative density of 1,879. When the temperature and pressure of 4-20 X 5 atm becomes liquid; Tsiklopropana boiling point at atmospheric pressure - 347 C. Malo soluble in water (one volume of gas at 20  + 2.85C soluble in water). Easy soluble in alcohol, petroleynom airwaves, chloroform and fatty oils.

     Cyclopropane obscheobezbolivayuschee had a strong effect. It is extremely flammable; His mixture of oxygen, nitrogen oxide and air can explode in contact with the flames, electrical sparks and other sources that could cause ignition. Using tsiklopropana must take all measures to exclude the explosion, including precautions associated with the use of electricity and rentgenoapparatury excluding education and static electricity. In connection with these characteristics, as well as the emergence of new ways and means of a general pain Cyclopropane now rarely used as a tool for anaesthesia. There Cyclopropane quickly. In April of concentration. % is analgeziyu, 6 on. off-consciousness about 8-10. % was anaesthesia (stage III), the concentration of 20-30. - deep anaesthesia.

     In the body Cyclopropane not destroyed, and provides an almost unchanged after 10 minutes after inhalation.

     Cyclopropane has expressed no effect on liver and kidney function; Several reduces Diurez. Sometimes when anaesthesia tsiklopropanom short hyperglycemia is associated with the initiation adrenoreaktivnyh systems. This effect less pronounced than in the application of airtime.

     Cyclopropane incident had an impact on holinoreaktivnye system and the body was somewhat slow pulse, possible arrhythmia. Influenced greatly increases tsiklopropana chuvsvitelnost Chavez to adrenaline; Your introduction of anaesthesia tsiklopropanom can cause ventricular fibrillyatsiyu.

     Blood pressure during anaesthesia slightly higher, which may lead to a slight increase bleeding.

     Cyclopropane used for the induction of anaesthesia and (Cyclopropane oxygen); Often used in combination with other means to narcosis (nitrous oxide, ether) and the muscles Ward. Showed patients with lung diseases, because it is an irritant mucous membranes airways. You can assign to liver disease and diabetes.

     Tsiklopropanovy anaesthesia can be used for short surgical intervention.

     Cyclopropane apply the mixture with oxygen to closed and semi-system (sometimes semi) using anaesthetic apparatuses with dosimeters. To maintain anaesthesia using 15-18% tsiklopropana. The introduction of anaesthesia is a higher concentration tsiklopropana. When finished filing tsiklopropana stop, and after 2-5 min. inhaling pure oxygen patients wake up.

     Filing oxygen must be continuous. Care should be taken to keep adequate ventilation and light was the release of the body's carbon.

     Sometimes Cyclopropane used as part <mixture Schein Ashmena>. After the opening of intravenous anaesthesia tiopental- sodium file (for semi-mode), a mixture of gases as follows: nitrous oxide-Part 1, Part 2-oxygen, CYCLOPROPANE - 0.4 parts.

     When using the mixture should be deleted after the pain narkotiziruyuschie components in sequence (to avoid development hypoxy): first stop filing tsiklopropana, after 2 to 3 minutes, nitrous oxide and even through the same time-oxygen.

     When dosing tsiklopropana anaesthesia runs smoothly, patients wake up quickly after inhalation. In case of overdose can stop breathing and the heart of oppression until the heart stops.

     Due to the rapid awakening after anaesthesia, patients may experience severe pain after surgery, so before the end of the operation to enter analgetik. After anaesthesia relatively frequent headaches, in some cases, postoperative vomiting, bowel paresis. So sick after awakening from anaesthesia require careful monitoring.

     In tsiklopropanovom anaesthesia counter introduction adrenaline and noradrenalina.

     Form release: seamless steel cylinders with a capacity of 1 and 2 litres of liquid tsiklopropana under the pressure of 5 atm; Cylinders painted orange color and is marked <gently. Cyclopropane. Flammable>.

     By applying tsiklopropana only medical personnel, past a briefing.

     Storage: in a cool place away from light sources.
