Hysteroscopy is an examination of the walls of the uterine cavity using optical systems. This method is used both for diagnostics and for the treatment of various gynecological diseases.
Hysterosalpingography was proposed in 1909 by N.M. Nemenov, who recommended introducing Lugol's solution into the uterine cavity to contrast the internal genital organs of women. Rindfleisch introduced a bismuth solution into the uterine cavity in 1910.
Hypoxic therapy, or normobaric hypoxia, promotes non-specific stimulation of the body's defenses. The mechanisms of the therapeutic effect of hypoxic therapy are unknown, but it can be assumed that its effect is realized by stimulating vital centers in conditions of oxygen starvation.
Colon hydrotherapy is a cleansing procedure that is performed in a medical facility by irrigating the colon with a large amount of liquid and has a beneficial effect on the body (especially the small intestine, kidneys, liver).
Holter monitoring (or Holter) is an immediate technique used to continuously record a patient's electrocardiogram (ECG) over a period of time, usually 24 hours.
Certain skills and abilities are required to perform ultrasound examinations of the hip joints of newborns in order to exclude congenital hip dislocations.
Ultrasound of the hip joints can be an additional method to clinical or X-ray examinations. It should be noted that ultrasound is more informative than MRI in detecting small effusions in the hip joint, even less than 1 ml.
Hip arthroscopy is performed under endotracheal anesthesia. The patient's position on the operating table is lying on the healthy side.
Hemofiltration is based on the use of a highly permeable membrane in a hemofilter, which is connected to an artery and vein using modified hemodialysis lines.
The study of eye hemodynamics is important in the diagnosis of various local and general vascular pathological conditions. The following main methods are used to conduct the study: ophthalmodynamometry, ophthalmoplethysmography, ophthalmosphygmography, rheoophthalmography, ultrasound Dopplerography.
Blood dilution (hemodilution) to reduce the concentration of toxic substances in it has long been used in practical medicine. This purpose is served by water loading (drinking copiously) and parenteral administration of water-electrolyte and plasma-substituting solutions.
Dialysis is a method of removing toxic substances (electrolytes and non-electrolytes) from colloidal solutions and solutions of high-molecular substances, based on the properties of some membranes to pass molecules and ions, but retain colloidal particles and macromolecules.
In the 80s, computer methods of obtaining images entered the practice of cardiology: digital coronary and ventriculography, computer tomography synchronized with the work of the heart, magnetic resonance imaging. Moreover, radiologists received special catheters for vascular plastic surgery and laser devices for evaporation of atherosclerotic plaques.
Hearing aid fitting is a complex of research, technical and pedagogical measures aimed at improving the hearing function for the social rehabilitation of hearing-impaired persons and improving their quality of life. This is an individual selection, adjustment of hearing aids and adaptation of the patient to its use.
