Minimal Inflation Tourniquet Pressure Using Induced Hypotension

2019-08-19 19:46:45 | BioPortfolio


Limb occlusion pressure (LOP) and arterial occlusion pressure (AOP) are the terms that mean the lowest tourniquet pressure required to stop the arterial blood flow into the limb distal to the cuff. LOP can be determined manually or automatically by slow cuff inflation until disapper of pulsation with Doppler flow-meter or pulse oximeter


The advantages of the tourniquet during upper or lower limb procedures are providing bloodless operative field and so less intra-operative blood lossIt has been reported that using the lowest effective inflation pressure minimize tourniquet induced nerve injury .). Limb occlusion pressure (LOP) and arterial occlusion pressure (AOP) are the terms that mean the lowest tourniquet pressure required to stop the arterial blood flow into the limb distal to the cuff. LOP can be determined manually or automatically by slow cuff inflation until disapper of pulsation with Doppler flowmeter or pulse oximeter .AOP can be estimated by a formula (AOP = [SBP + 10]/KTP) using patient's systolic blood pressure (SBP) and tissue padding coefficient (KTP) values. In both methods, addition of a safety margin to LOP or AOP is recommended for potential hemodynamic fluctuations during surgery

Two Mathematical Methods to Estimate Arterial Occlusion Pressure and Tourniquet Effectiveness in Lower Limb Surgery

Pneumatic tourniquets are widely used not only to reduce blood loss and to ensure optimal operating conditions during extremity surgery, but also in regional anesthesia (local intravenous)...

The Venous Distension Reflex and Orthostatic Hypertension

This research is being done to find out whether distension of veins in legs will cause a rise in blood pressure (orthostatic hypertension).

A New Technique for Determining Limb Occlusion Pressure

This study evaluates a novel technique for measuring the minimum pressure necessary to achieve a bloodless surgical field, known as a patient's limb occlusion pressure (LOP). Patients will...

Venous Occlusion and Limb Swelling

Problems affecting the veins in the legs can cause discomfort and swelling. We want to see how artificially and reversibly blocking the leg veins affects swelling in the lower limb.

Minimizing Tourniquet Pressures in Paediatric Orthopaedic Knee Surgery

Tourniquet cuffs are routinely used to stop blood flow in patients' arms or legs during surgery. This allows surgeons to better visualize anatomical structures during the procedure. Altho...

Intra-Arterial Thrombolysis Improves the Prognosis of Acute Ischemic Stroke Patients without Large Vessel Occlusion.

Intravenous thrombolysis is known as the only effective reperfusion therapy for acute ischemic stroke (AIS) caused by small branches occlusion. However, it is still unclear whether intra-arterial thro...

Optimizing Mean Arterial Pressure in Acutely Comatose Patients Using Cerebral Autoregulation Multimodal Monitoring With Near-Infrared Spectroscopy.

This study investigated whether comatose patients with greater duration and magnitude of clinically observed mean arterial pressure outside optimal mean arterial blood pressure have worse outcomes tha...

Inner thigh friction as a cause of acne mechanica.

Acne mechanica is defined as being any acneiform eruption in areas of friction, pressure, stretching, rubbing, pinching, or occlusion of the skin in any individual, regardless of preexisting acne. Var...

Comparison of cardiovascular parameter estimation methods using swine data.

In this study, new and existing methods of estimating stroke volume, cardiac output and total peripheral resistance from analysis of the arterial blood pressure waveform were tested over a wide range ...

Noninvasive Intracranial Pressure Estimation With Transcranial Doppler: A Prospective Observational Study.

Transcranial Doppler (TCD) ultrasonography has been described for the noninvasive assessment of intracranial pressure (ICP). This study investigates the relationship between standard, invasive intracr...

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.

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).

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.

An occlusion resulting in overstrain and injury to teeth, periodontal tissue, or other oral structures.

Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
