conclusion results reinforced the pivotal role of vascular geometry, with respect to hemodynamics, together with the importance of performing patient-specific cfd analyses, through which the effect of different blood flow conditions on the aneurysm hemodynamics could be evaluated. objectives this study aimed to investigate the effects of variations in heart rate and internal carotid artery (ica...

conclusions this study suggests that obese patients in hs may have a higher risk of hemodynamic instability compared to their nonobese counterparts primarily due to obesity-induced increases in intra-abdominal pressure resulting in reduced venous return. results in hemorrhage simulation, moderate increases in bmi were found to produce greater decreases in map and co compared to the normal subje...

introduction: the effect of severe soft tissue injury on the severity of hemorrhagic shock is still unknown. therefore, the present study was aimed to determine hemodynamic and metabolic changes in traumatic/hemorrhagic shock in an animal model. methods: forty male rats were randomly divided into 4 equal groups including sham, hemorrhagic shock, soft tissue injury, and hemorrhagic shock + soft ...

echocardiography is a non-invasive diagnostic technique which provides information on cardiac morphology, function, and hemodynamics. it is the most frequently used cardiovascular diagnostic test only after electrocardiography. in less than five decades, the evolution in this technique has made it the basic part of cardiovascular medicine. herein, the evolution of various forms of echocardiogra...

normal 0 false false false en-us x-none fa microsoftinternetexplorer4 we read with great interest the article by minakari et al. regarding the effects of treatment with subcutaneous octreotide and oral midodrine in cirrhotic patients with ascites who continued to receive their standard diuretic treatment 1 and we would like to comment on their results. first, the administration of midodrine for...

conclusions it seems that, in patients undergoing pncl, sa is as effective and safe as ga. patients who undergo pncl under sa require smaller amounts of analgesic dose and show hemodynamic stability during surgery and recovery time. also, sa technique provides decreased blood loss and shortened surgery as well as anesthesia times compared to ga. results map and heart rate show no significant di...

background:organophosphates are commercially available agrochemicals for pest control, but may be abused for deliberate self-poisoning. we report a case of suicidal ingestion of dimethoate, a moderately toxic organophosphate insecticide, which can cause refractory hemodynamic instability, and the successful use of methylene blue (mb) for counteracting this complication. case presentation: an un...

background: this study was designed to investigate the effect of intravenous magnesium sulfate on hemodynamic changes induced by pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. methods: a randomized, placebo controlled study was performed on 52 asa class i or ii aged 20-70 years patients undergoing laparoscopic cholecystectomy with pneumoperitoneum with carbon dioxide. bef...

conclusions we concluded that propofol can reduce sbp, dbp, map, hr & cough production at the time of injection but there were no significant changes in these parameters after extubation. results heart rate and blood pressure in patients receiving propofol were less than the control group (p < 0.05) at the time of injection of propofol, but there were no differences between the two groups at th...

conclusions intravenous acetaminophen administered before caesarean section reduced tachycardia after intubation, narcotic drugs administration during and after the operation and reduced pain in pacu. results patients in the saline group experienced more pain in the recovery room (vas 7.0 ± 1.24 vs. 6.15 ± 2.27; p value = 0.041) and required more fentanyl intraoperatively (150 µg vs. 87.7 ± 75;...
