Assessment of Automatic Relays by Intensive Basis Advantage Compared With Manual Relays, on the Hypotension Risks, During Noradrenalin Administration

Circulatory failures are the main cause of admissions in the intensive care unit. It is recommended to prescribe to these patients an intravenous injection of catecholamine to correct this dysfunction and to keep an hemodynamic stability. Electric pumps are used to administrate a continuous flow of drugs to patient. When a syringe of drugs ends, it is replaced by a full syringe, it is named "relay". This change may cause a flow interruption and hypotension.

In the intensive care unit at CHD Vendee, the manual relays used in common practice will cause hemodynamic instabilities : hypotensions in 20% cases. Since 4 years, new devices are also used to make the relays. It is "smart pumps" allowing to manage automated the drug delays. This new method allows to not interrupt the drug flow. It could reduce the occurence of hypotension. A 50% decrease of relative number of hypotension will show that the use of automatic method is the most sure medical strategy.

Our study want to compare manual and automatic method watching the variations of medium arterial pressure (MAP) during the fifteen minutes after the relay compared to baseline (MAP before the relay). Noradrenalin is the catecholamine most administrated so we choose to study only the relay for this drug.

Medical and Biotech [MESH] Definitions

The blood pressure in the ARTERIES. It is commonly measured with a SPHYGMOMANOMETER on the upper arm which represents the arterial pressure in the BRACHIAL ARTERY.

A significant drop in BLOOD PRESSURE after assuming a standing position. Orthostatic hypotension is a finding, and defined as a 20-mm Hg decrease in systolic pressure or a 10-mm Hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. Symptoms generally include DIZZINESS, blurred vision, and SYNCOPE.

Procedure in which arterial blood pressure is intentionally reduced in order to control blood loss during surgery. This procedure is performed either pharmacologically or by pre-surgical removal of blood.

Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.
