The aim – analyze modern Russian and foreign literary sources in order to determine modern means for treating the hands of the surgeon and the operating field. Results. One of the key points in the prevention of surgical infection is the treatment of the surgeon’s hands and the operating field with effective skin antiseptics in order to destroy pathogenic and opportunistic microorganisms that colonize intact skin. In modern practice, skin antiseptics are predominantly used containing alcohols as active substances, in particular ethyl, propyl and isopropyl, halogenated substances such as iodine and iodophores, guanidines, which include chlorhexidine digluconate, as well as quaternary ammonium compounds. Moreover, the most widespread are combined preparations containing several active substances and functional additives, which makes it possible to neutralize the negative properties of various active substances. Also, an interesting and promising direction is the use of polymer operating films or film-forming antiseptics. Currently, research is being actively carried out aimed at finding and developing modern highly effective antiseptic agents and their rational combinations that meet the necessary requirements, are optimal in their properties, cost-effective and comfortable to use.

The Way

A new special endotracheal tube for ventilating patients during microlaryngeal surgery is described. It is 6.25 cm long, made of silicone elastomer and has a “soft” cuff built onto it. It is placed below the patient's cords and the cuff blown up while the patient is paralyzed, and under anesthesia. The patient's lungs can be ventilated by jetting oxygen from the jet tube which is built into it. While the oxygen is not flowing the patient can passively exhale through the tube and cords. Obstruction to the surgical field is minimal and consists of the cuff inflating tube .08 cm in diameter and the jet tube .25 cm in diameter which will be in the posterior commissure out of the way. The tube is designed in such a way that both during inflation and exhalation gas is blown out through the cords to help to blow blood and debris away from the operating field.

Industrial Gas Turbine

Industrial gas turbine rotors sometimes require a journal bearing in a region of the machine surrounded by compressor discharge air. Ambient temperatures in this region may exceed 600 F (588 K), which poses a challenge to bearing designers. The present paper describes housing design approaches to meeting this challenge, an experimental program to evaluate them, and the application of results to operating field units. The experimental program was carried out in a special test facility on full-size housings for a 14-in. journal bearing in a hot, pressurized environment.

Abstracts. Surgery. A. A. Ozereliev (Zentralbl. F. Chir. 1930, No. 3) based on a comparison It is recommended to use a 5% alcoholic solution of tannin for disinfection of the operating field, since the latter, with the same disinfecting force with t. jodi does not irritate the skin. To eliminate stains, it is recommended to wash them off after surgery with 1% oxalic acid solution.
