[Dynamics of the morphological changes in a burn wound during treatment in a controlled abacterial environment].

Histological and histochemical research methods were used to examine the healing of burn wounds treated under bandage and in monitored abacterial environment (open type treatment). Biopsies of burn wounds were investigated in 40 patients. It was shown that upon the treatment in abacterial environment the wound heal 10-12 days more rapidly as compared to those treated under bandage. Upon open type treatment there was an early appearance of fine granulations with marked macrophagal and fibroblast reactions, whereas under bandage there formed edematic granulations with high content of lymphoid and plasma cells.

Preparation of nonmedical personnel in the operating room environment.

The nonmedical visitor to the operating room often provides vital expertise in the effective care and treatment of the surgical patient using today's sophisticated technology. By becoming aware of the special environment in the operating room and following the guidelines set up by each institution, the biomedical equipment technician, clinical engineer, or manufacturer representative will enhance his or her effectiveness when the need for entering the operating room suite arises. Guidelines cover personal hygiene and clothing and antisepsis techniques (scrubbing, gowning, draping, patient preparation, and equipment cleaning) to prepare for the operating. The visitor in the OR must also observe rules of etiquette to guard against interference with the established procedure routine.

[Morphology of the suppurative wound in the treatment process in a regulated environment].

Morphological and histochemical studies of biopsies from the areas of purulent wounds in the process of their treatment in a chamber with regulated environment were carried out. After 2-week course of treatment the purulent wound heals like a pure surgical wound. The granulation tissue contains a small number of leukocytes, the vessel is filled with polymorphonuclear leukocytes. A typical feature is the presence in the wound of lymphoid cell infiltrates in the maturing granulation tissue which indicates enhanced immune processes in the host. The results of treatment show that treatment of purulent wounds in a regulated environment considerably improves the condition of the wound contributing to its purification and stimulating healing processes in it.

[Device for sampling and feeding under aseptic conditions].

The scheme and operating principle of a device for sampling and feeding under aseptic conditions are discussed. The device provides sterility of the elements used for sampling and feeding and excludes the contact of the liquids with the environment. The results of the study on the device temperature fields substantiated the sterilization regime using the parameter of the aseptic efficient. The sterilization period is 10 minutes which decreases the steam consumption and increases the production efficiency.

The surgeon's garb.

A comprehensive evaluation of all factors associated with the surgeon's garb worn with and without laminar air flow revealed that in a conventional operating room, all personnel should wear an impermeable one-piece suit with foot attachments, any type of head cover, and, if they are going to be near the operative site or instrument table, a disposable mask. Scrub personnel should wear some type of a disposable gown to reduce the amount of surface contamination. The best way to reduce the environmental and surface contamination would be for all personnel to wear some type of a hooded exhaust equipment, but this is impractical both for circulating nurses and for anesthesiologists. Despite the reduction obtained from all the above controls, the reduction in the amount of bacterial contamination would not be as great as that obtained with laminar air flow, 93% (p < 0.005). Laminar air flow produced the greatest single reduction in environmental and surface contamination and variables such as time, people and attire did not influence the overall counts. The attire recommended for the conventional operating room can be used in laminar air flow with an expectation of overall reduction in contamination.

Maintenance of aseptic barriers in the conventional operating room: general principles.

Contamination of operative wounds during surgery occurs primarily through contact and secondarily through the airborne route. Inspection and maintenance of air-handling equipment is essential, with special reference to air intakes, filters, humidifiers, and exhaust systems. Doors should remain closed to maintain positive pressure. Surgical attire for all personnel must provide for complete coverage of hair and arms. Intensive interim cleaning of all horizontal sufaces between operations is essential. The infection rate is proportional to the duration of the operation and the number of personnel in the room, and inversely proportional to the air changes per hour.

[Bacterial toxic shock as a complication of calculous pyelonephritis].

The causes of bacteriotoxic shock were examined in 33 patients (11 lethal outcomes). It has arisen as a complication of treatment given to 7830 patients for urolithiasis. Aggravation of chronic pyelonephritis, occlusion of the urinary tracts, urogenital mucosal and parenchymal injuries, low resistance to infection contribute to microbacteria and their toxins entering blood with resultant bacteriotoxic shock. Transcutaneous operative interventions, therapeutic and diagnostic procedures also produce high risk of blood infection with gram-negative microflora, especially in violation of asepsis and antisepsis rules. As shown by microflora tests, the dominating bacteria consisted of opportunistic agents which had acquired the resistance to antibacterial drugs. In view of rapid progression of bacteriotoxic shock therapeutic efforts should be concentrated on fast normalization of hemodynamics, recovery of urine passage, introduction of sorption detoxication, prevention of DIC syndrome. The schemes of combined antibiotic treatment adjusted to the kind of infectious agent are suggested.

[Bacterial flora and preventive antibiotic treatment in open fractures].

In 172 patients with open fractures of long tubular bones the wound bacterial flora was studied on their admission to the clinic and in occurrence of suppurative complications. There were no cases of "outdoor" microorganisms being the cause of suppuration. Pathogenic agents of suppurative infection differed from "outdoor" strains in their species content, signs of pathogenicity, sensitivity to antibiotics. As a rule, suppuration was preceded by soft tissues necrosis. Since wound suppuration was produced not by the initial or changed "outdoor" microorganisms but hospital strains, which penetrate in the wound due to inadequate observation of the rules of asepsis and antisepsis in surgical treatment or subsequent dressing, then prophylactic antibioticotherapy should cover mostly sensitivity of hospital bacterial strains. To this end, the study of bacteriological background for each surgical department seems to be absolutely necessary. In a small zone of the soft tissues injury under conditions of secure fixation of bone fragments with Ilizarov apparatus a limited use of antibiotics is believed to be permissible.
