|---|---|
| intravenous pyelogram | <investigation, radiology> A special diagnostic test that follows the time course of excretion of a radiopaque contrast dye through the kidneys, ureters and bladder after it is injected into a vein. (30 Mar 1998) |
| intravenous pyelography | Former name for intravenous urography. (05 Mar 2000) |
| intravenous regional anaesthesia | Regional anaesthesia by intravenous injection of local anaesthetic solution distal to an occlusive tourniquet in an extremity previously exsanguinated by pressure or gravity. Synonym: Bier's method. (05 Mar 2000) |
| intravenous tension | The pressure of the blood within a vein, the venous pressure. (12 Dec 1998) |
| intravenous urography | Excretory urography, radiography of kidneys, ureters, and bladder following injection of contrast medium into a peripheral vein. Retrograde urography, radiography of the urinary tract following injection of contrast medium directly into the bladder, ureter, or renal pelvis. Synonym: cystoscopic urography. (05 Mar 2000) |
| tension, intravenous | The pressure of the blood within a vein, the venous pressure. (12 Dec 1998) |
| fat emulsions, intravenous | Emulsions of fats or lipids used primarily in parenteral feeding. (12 Dec 1998) |
| alveolocapillary block | The presence of material that impairs the diffusion of gases between the air in the alveolar spaces and the blood in alveolar capillaries; block can be caused by oedema, cellular infiltration, fibrosis, or tumour, and results in undersaturation of peripheral arterial blood with oxygen. (05 Mar 2000) |
| anterograde block | Conduction block of an impulse traveling anywhere in its ordinary direction, for example, from the sinoatrial node toward the ventricular myocardium. (05 Mar 2000) |
| arborization block | Intraventricular block supposedly due to widespread blockage in the Purkinje ramifications and manifested in the electrocardiogram by a pattern similar to bundle-branch block but with complexes of low amplitude. (05 Mar 2000) |
| atrioventricular block | <cardiology> A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998) |
| autonomic nerve block | Interruption of sympathetic pathways, by local injection of an anaesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block. (12 Dec 1998) |
| A-V block | <cardiology> A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998) |
| block | An obstruction or stoppage. (18 Nov 1997) |
