Results Most patients had a significant improvement of hemodynamics after the operation. the PaO 2 was increased from 9.41±0.72 to 10.00±0.85kPa ( P <0.01),P(A-a)O 2 was decreased from 2.60±0.78 to 1.77±0.75kPa ( P <0.005).
Hemodynamic was determined before anesthesia,1 min(at that time urapidil and esmolol were injected intravenously respectively),3 min,5 min,7 min and 10 min after cervical plexus block.
Hemodynamic examination showed that the diameters of splenic and portal vein as well as the blood flow were decreased in all the groups (t = 3.6153, P = 0.0004; t = 6.8052, P = 0.000), es-pecially significant in group C (t = 6.3969, P = 0.000).
The heart load and hemodynamic response effects of CO on CO-exposed workers showed:the level of COHb(8.88%),Hb(156.53g/L),mean corpuscular volume(MCV 46.32%)in CO-exposed workers were more significantly increased than that of control group(3.84%,145.05g/L, 43.61%).
对某瓷厂造气车间55名 CO 作业工人心脏负荷、血液动力学等指标进行配对研究,结果表明作业工人 COHb 8.88%,Hb156.63g/L,红细胞比积46.32%,显著高于对照组(3.84%,145.05g/L和43.61%)。
The results showed that there were diff ences in the haemodynamics and blood gas among the COPD without HPH group (8 cases), the COPD with HPH group (13 cases) and the cor pulmonale group (28 cases). The differences were that mPAP,TPR, HR, PaCO_2 increased gradually and Cpa, PaO_2 decreased progressively during the process from COPD to cor pulmonale.
Results The oxygen supply was significantly better after general anesthesia induction,cerebral oxygen metabolic rate was lower than before anesthesia induction in the two groups,but CERO_2 was more significantly decreaseds in propofol group than in etomidate group(P<0.05),the haemodynamics was more stable in etomidate group than propofol group.
We used acute myocardial infarction model induced by ligation of left coronary artery in rats to investigate the effect of propofol and midazolam upon haemodynamics、heart function、 myocardial infarction size、ultrastructure of myocardial tissue following infusion with propofol and midazolam.
Objective To observe the effect of anesthesia with different doses of remifentanil in thoracic surgery on haemodynamics and cortisol concentration,and provide the theory base for the reasonable use of remifentanil in thoracic surgery.
The protection of group A is much more better than group D, regardless of haemodynamics or myocardial enzymology and his tomorphology. group A is better than the other two groups, displaying dose dependent.
Observer’s assessment of alertness/sedation(OAA/S) score was achieved, at which the value of bispectral index(BIS), haemodynamic variables and dosage of propofol were recorded.
Results before and afer experinment, the maternal haemodynamic parameters,i. e. heart rate(HR), stroke volume (SV), stroke index (SI), cardiac output (CO), cardiac index (CI), ventricular pump efficacy(VPE), mean arterial pressure (MAP), and total peripheral resistance(TPR), did not change significantly in eithergtoup(P> 0. 05);
Objective:To evaluate the haemodynamic change and its role in the pathogenesis of avascular necrosis of the femoral head(ANFH)by selective digital subtraction angiography(DSA).
The electrophysiologic and haemodynamic effect of captopril was studied in experimentalmodels of acute inferior myocardial infarction and compared in anterior infarction models.
Statistically significant differences were found in the values of central hemodynamics, physicochemical homeostasis, the level of oxygen consumption by the tissues and general nonspecific adaptation reactions of the body.
The sleep quality influenced the restoration of hemodynamics more than that of the cardiac rhythm, mainly when obstructive sleep apnea syndrome was present.
The data on the baseline investigation of risk factors, the determination of cerebrovascular hemodynamic parameters (CVHP), and stroke follow-up were analyzed.
In multivariate analysis, hemodynamic score, age, sex, cigarette smoking, family history of stroke and systolic blood pressure were selected by the Cox regression for inclusion in the final analysis.
Echocardiographically guided pericardiocentesis was performed immediately and after evacuation of 80 ml of hemorrhagic pericardial fluid haemodynamics stabilized.
Haemodynamics, significant risk of endocarditis with chronic inflammatory bowel disease and obligatory glucocorticoid treatment were indications for fistula closure.
The effect of propranolol on cardiac mechanics and haemodynamics was examined on isolated papillary muscle as well as in situ in the closed thorax in euthyroid and hyperthyroid cats.
The right ventricle plays a pivotal, yet often neglected role in the circulation and its failure is often responsible for haemodynamic instability and poor outcome.
In the diagnosis of right ventricular failure, echocardiography is superior to invasive haemodynamic monitoring and allows for choosing the best therapy and following its effects.
