Filter by:This study compares the actual standard of care with a new protocol to guide hemodynamic optimization during major abdominal surgery, which is more tailored on patient real needs. During general anesthesia metabolic needs of the body are markedly reduced and increase in CO may not be necessary. In addition, excessive fluid administration has been related to worse post-operative outcomes. We divide patients into three groups: the standard treatment group, the NICE protocol group and the intervention group. In this group we use the v-aCO2/CaO2-CvO2 as marker of tissue ability to increase their oxygen consumption in response to increased O2 delivery, and based on this index the administration of fluid. The principal aim is to optimize functional hemodynamics in order to reduce the fluid balance at the end of the surgery.
This is a clinical trial which will investigate whether administration of caffeine, a respiratory stimulant, to preterm babies soon after birth can prevent the need for a breathing tube, or intubation. Many preterm babies who require intubation are intubated soon after birth, often within the first few hours. If caffeine is given early enough and is sufficient to stimulate effective breathing, perhaps these babies may not require intubation. Additionally, caffeine may improve blood flow in preterm babies when given soon after birth. Approximately half of babies in this study will receive caffeine within two hours after birth, and half will receive caffeine 12 hours after birth. The hypothesis is that preterm babies who receive caffeine within 2 hours after birth will have a lower incidence of intubation than preterm babies who receive caffeine 12 hours after birth. The main secondary hypothesis is that caffeine given soon after birth will enhance blood flow in preterm babies.
This study aims to Analyze and compere the hemodynamic and respiratory variables before, during and after the applying of technic as well as evaluate respiratory pressures generated during applying of this same technic and correlate them with the effort noticed by device user.
To evaluate the impact of perioperative, algorithm driven, hemodynamic therapy based on individualized fluid and cardiac output optimization on postoperative moderate and severe complications in patients undergoing major abdominal surgery including visceral, urological, and gynecological operations. In the proposed study, hemodynamic therapy is tailored individually to each patient, based on individual preload optimization by the functional parameter "pulse pressure variation (PPV)" and based on an individually titrated goal of cardiac index. The proposed study therefore further develops the concept of hemodynamic goal-directed therapy to individually set goals and is designed to assess its impact on morbidity and mortality.
The objective of this study is to use local topical anesthesia to numb the sensory input, captured by branches of the Trigeminal nerve found on the skin in and around the eye, to decrease a hemodynamic reflex seen during placement of a catheter for intra-arterial chemotherapy (IAC) for eye tumors in children. This Trigeminal-cardiac reflex brings about hemodynamic instability during general anesthesia. Normally, one could block this sensorial input with ophthalmic peribulbar placement of local anesthetics, but these eyes have malignant growth and invasive procedures may cause more harm. The investigators are aiming to numb the sensory branches of the trigeminal nerve non-invasively and observe for any decrease in these events.
The use of opioid during surgery can cause side effects and may delay hospital discharge. Some studies have shown balanced sparing opioid anesthesia can optimize the side effects and and the time of discharge. In this compared controlled randomized study the aim is to evaluate the intraoperative and postoperative pain, hemodynamic effects, nausea/vomiting, postoperative ileus, sedation, urinary retention, time of discharge PACU Post anesthesia care unit and hospital.
Hemodynamically unstable ventilated PICU & PCICU patients, which a decision for commencement in inotropic therapy or fluid bolus has been made, will be recruited. Hemodynamic measurements will be carried out before and after therapy have been made, including customary hemodynamic parameters, echocardiography and USCOM studies. All parameters will be analyzed for fluid responsiveness or inotropic therapy prediction. Trend in USCOM parameters will be compared to echocardiography CO parameters.
The gold standard in hemodynamic evaluation has been the combined use of echocardiography and right heart catheterization. Fall backs to echocardiography are its time consumption and requirement for specialist interpretation while the Swan-Ganz® catheter shows a poor correlation of central venous pressure to volume status and provides indirect and difficult to interpret measurements in patients with unique pathophysiological states. Next generation continuous hemodynamic transesophageal echocardiography (hTEE®) is being increasingly utilized to assist with complex resuscitations and to monitor the hemodynamic profiles of critically ill patients. hTEE is proving to be an essential diagnostic, therapeutic and monitoring tool for the rapid evaluation of the hemodynamic state in the critically ill patient and or hemodynamically compromised patient. The purpose of this observational study is to evaluate the role of hTEE in clinical decision-making in 30 patients recruited from OR-Trauma and in 30 patients from the Cardiovascular-OR. Hemodynamic trans-esophageal echocardiography (hTEE) incorporates an FDA-approved miniaturized, disposable probe for continuous use in patients for up to 72 hours. This device has been used for postoperative assessment in the ICU for several years with successful placement of probes and without any adverse incidents. The probe allows for the rapid, intermittent or continuous evaluation of bi-ventricular function, volume status and valve function at bedside or intraoperatively. It also allows for the evaluation of pericardial effusions and or the exclusion of pericardial tamponade.
The purpose of the study will be to record the hemodynamic response measured by traditional methods (non-invasive blood pressure and ECG) and Pressure Recording Analytical Method in patients undergoing laryngeal mask placement compared with the hemodynamic response measured in patients undergoing laryngoscopy and tracheal intubation for performing surgery in gynecological area and assess the differences with the two methods.
This study aims to describe the ratio of the diameter of inferior vena cava to the common femoral vein measured by ultrasonography in critically ill patients with shock, and to evaluate the potential link between this ratio and the existence of intra-abdominal disease.
