Disease relevance of Thermodilution

 

High impact information on Thermodilution

  • Arterial and femoral venous blood gas data were obtained and coupled with simultaneous measurements of femoral venous blood flow (Qleg) by thermodilution to obtain O2 delivery and oxygen uptake (VO2) [6].
  • INTERVENTIONS: Invasive hemodynamic measurements were done (using a balloon-tipped thermodilution catheter) before and for 3 hours after a single oral dose of 50 mg of encainide [7].
  • In protocol 1, cardiac output (CO) and stroke volume (SV) were measured by MRI and thermodilution (TD) in 15 mice (3 L1, 4 L2, 8 LC) [8].
  • Central hemodynamic measurements, leg blood flow determined by thermodilution, and systemic and leg metabolic parameters were measured during maximal treadmill exercise before and 2 hours after clonidine 2 micrograms/kg IV (n = 15) or 0.9% normal saline (n = 5) [9].
  • ET-1 and big ET-1 reduced coronary sinus blood flow, measured with thermodilution by a maximum of 25 +/- 4% and 28 +/- 8% and increased coronary vascular resistance by 50 +/- 9% and 107 +/- 26%, respectively [10].

Associations of Thermodilution with chemical compounds

  • In 10 of the 13 patients, coronary sinus blood flow was measured by coronary sinus thermodilution technique at rest and after dipyridamole infusion (0.5 mg/kg in 15 minutes) 10 +/- 5 days after quantitative coronary arteriography [23].
  • In 18 patients (13 men and five women, 30 to 76 years old), coronary sinus blood flow (by thermodilution) was measured before and during intracoronary administration of nitroglycerin, 25 micrograms, both before and 5 min after a 15 min intravenous infusion of (1) 5% dextrose in water (n = 8, control) or (2) 100 mg/kg N-acetylcysteine (n = 10) [24].
  • The changes in coronary blood flow in response to intracoronary injection of 3 ml of 76% Renografin were studied in 47 patients using the thermodilution technique for continuous measurement of coronary sinus blood flow [25].
  • To determine whether hydralazine improves O2 transport to working muscle, we examined the effect of intravenous hydralazine on blood flow (measured by thermodilution) and metabolism in the leg during maximal upright bicycle exercise in 10 patients with chronic heart failure [26].
  • LBF was determined by thermodilution: LGU = arteriovenous glucose difference (AVGdelta) x LBF [27].
 

Gene context of Thermodilution

  • 1. Cardiac index (CI) calculated by the conventional method and thermodilution (TD) showed acceptable correlation (r = 0.90, CITD = 1.20 CIPWD + 357; r = 0.86, CITD = 0.90 CICWD + 262) for pulsed (PWD) and continuous wave (CWD) Doppler, respectively, but with systematic underestimation (-28 +/- 13%, p < 0.01) by pulsed wave Doppler [28].
  • METHODS: We prospectively assessed long-term follow-up and predictors of survival in 62 consecutive patients referred from 1990 to 1992 for evaluation of idiopathic dilated cardiomyopathy, including haemodynamic evaluation, thermodilution right ventricular ejection fraction and volume measurements [29].
  • The Arrow "Hands-Off" thermodilution catheter (AHO) is completely shielded during balloon testing, preparation, and insertion [30].
  • Cardiac output was simultaneously measured by thermodilution to calculate whole body extraction of ANP [31].
  • OBJECTIVE: To evaluate the accuracy and precision of continuous thermodilution (CCO) by using a validated bolus thermodilution (BCO) reference technique as criterion standard [32].
