Attenuating Haemodynamic Response to Laryngoscopy and Intubation

2023
Background: Laryngoscopy and endotracheal intubation for airway management produces intense noxious stress response appearing as an alteration in systolic blood pressure, diastolic blood pressure, mean arterial pressure and heart rate which could be life threatening in selected group of patients.

HAEMODYNAMIC RESPONSE TO ACTH ADMINISTRATION IN ESSENTIAL HYPERTENSION

Clinical and Experimental Pharmacology and Physiology, 1981
SUMMARY1.The haemodynamic and volume response to ACTH administration was investigated in six patients with mild, untreated essential hypertension and two patients with Addison's disease on maintenance steroids. Blood pressure, heart rate and weight were recorded daily.

Importance of endothelial function in stenotic haemodynamic responses

Cardiovascular Research, 1991
The aim was to examine endothelium mediated flow dependence in a dynamic stenosis.The coronary circulation was modelled as a proximal compliant stenosis and a fixed distal resistance. Pressures and flow were calculated using standard haemodynamic equations.

Non-invasive continuous haemodynamic monitoring and response to intervention in haemodynamically unstable patients during rapid response team review

Resuscitation, 2019
During rapid response team (RRT) management of haemodynamic instability (HI), continuous non-invasive haemodynamic monitoring may provide supplemental physiological information.To continuously and non-invasively obtain the cardiac index (CI) and mean arterial pressure (MAP) in patients with HI at baseline and during RRT management using the ClearSight™

[Venous haemodynamics response to hypercapnia].

Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova, 2007
The authors' aim was to evaluate the response of the intracranial venous system to application of functional tests. In 46 healthy volunteers, the basal veins were examined using venous transcranial color-coded duplex sonography. We evaluated angle-corrected venous peak-systolic flow velocities (V(vb)) in response to hypercapnia (I group: 29 subjects ...

Haemodynamic responses to conflict stress in borderline hypertensive rats

Journal of Hypertension, 1989
Chronic exposure to a shock-shock conflict paradigm (2 h/day, 5 days/week for 12 weeks [1]) produces hypertension in the borderline hypertensive rat (BHR), a cross between the spontaneously hypertensive rat (SHR) and the Wistar-Kyoto rat (WKY). The purpose of the present study was to characterize the regional haemodynamic responses which take place ...

Renal Haemodynamic Responses to Adenosine in Acute Renal Failure

Nephron, 1995
Renal vascular reactivity was studied in rats with acute renal failure (ARF) to investigate whether changes in sensitivity to the renal haemodynamic effects of adenosine can explain why adenosine plays a significant role in some but not all forms of ARF.

Regional and systemic haemodynamic response to aortography in hypertensives

Journal of Hypertension, 1999
To study the effects of aortography and of aortic counterflow bolus injection per se on regional and systemic haemodynamics in hypertensives in comparison to normotensive matched controls.Mean blood velocity (MBV) and pulsatility index (PI)--as an index of regional vascular resistance--by the Doppler technique, at the femoral, common carotid and ...

Clinical vs haemodynamic response to drugs in portal hypertension

Journal of Hepatology, 1998
The combination of non-selective beta-blockers and nitrates is an effective therapy for the prevention of rebleeding from oesophageal varices. However, a significant number of patients fail to respond and have further haemorrhage. It has been suggested that measurement of the hepatic venous pressure gradient response to long-term drug therapy may allow

Difference in Haemodynamic Response to Prostaglandins A and E

Nature, 1971
PROSTAGLANDINS A and E are vasodepressor substances, the effect of which has been attributed to direct vasodilator action on peripheral arteriolar smooth muscle1–7. The mechanism of the hypotensive effect of the two prostaglandins may not, however, be identical.
