Hasson Technique: From 1 Different Sources
a technique used in laparoscopic surgery in which the skin, muscle, fascia, and peritoneum are incised under direct vision to allow the insertion of a blunt *trocar, through which the laparoscope is introduced. [H. M. Hasson (21st century), US gynaecologist]
Not septic; free from septic material technique.... aseptic technique
Ways of producing images of body organs that record, process and analyse sound waves, radio waves or X-RAYS passing through or generated by the body’s tissues. ULTRASOUND scanning using high-frequency, inaudible sound waves directed at the area of the body being studied is the most generally used scanning procedure. Sound waves are re?ected more powerfully by some structures than others, and a pattern of those re?ections is detected and shown on a screen. Other screening methods include COMPUTED TOMOGRAPHY, magnetic resonance imaging (MRI), positron emission tomography (PET SCANNING) and RADIONUCLIDE scanning, which measures the di?erential uptake of radioactive materials in the body’s tissues.... scanning techniques
An iterative group judgment technique in which a central source forwards surveys or questionnaires to isolated, anonymous (to each other) participants whose responses are collated/summarized and recirculated to the participants in multiple rounds for further modification/critique, producing a final group response (sometimes statistical).... delphi technique
A face-to-face group judgement technique in which participants generate silently, in writing, responses to a given question/problem; responses are collected and posted, but not identified by author, for all to see; responses are openly clarified, often in a round robin format; further iterations may follow; and a final set of responses is established by voting/ranking.... nominal group technique
A therapy that aims to improve health by teaching people to stand and move more efficiently. The technique is based on the belief that bad patterns of body movement interfere with the proper functioning of the body and contribute to the development of disease.... alexander technique
A method taught to couples who are experiencing sexual difficulties caused by psychological rather than physiological factors. The aim of the technique is to make both partners more aware of pleasurable bodily sensations, and to reduce anxiety about performance. It is particularly effective in treating loss of sexual desire (see sexual desire, inhibited), or inability to achieve orgasm (see orgasm, lack of), and in helping men to overcome impotence or premature ejaculation (see ejaculation, disorders of).... sensate-focus technique
a technique for creating a mechanical bond between resin-based materials and the enamel of teeth; it is used to retain and seal the margins of composite fillings, to retain brackets of fixed orthodontic appliances, and to retain resin-based *fissure sealants and adhesive bridges. Phosphoric acid is used to create a porous surface into which a bonding agent can flow.... acid-etch technique
a technique for removing a stone from the ureter. It consists of ‘pushing’ the stone back into the renal pelvis, where it can be destroyed by *lithotripsy (‘bang’).... push-bang technique
a method for introducing a catheter into a blood vessel or cavity. First, a needle is used to puncture the structure, then a *guidewire is passed through the needle. The needle is removed, and the catheter is introduced over the wire. The technique is used in angiography, cardiac catheterization, cannulation of large veins, and drainage of abscesses and other body cavities. [S. I. Seldinger (1921–98), Swedish radiologist]... seldinger technique
