Filter by:INTRODUCTION: Most studies on analgesia in pregnant women in labor mainly evaluate the effect of anesthetics on pain, mentioning hypotension as a side effect without investigating its impact on fetal well-being. The objective of the present study is to evaluate the efficacy of the use of low doses of local anesthetic (LA) to prevent hemodynamic alterations that manifest as a loss of fetal well-being. METHODOLOGY/DESIGN: It is a randomized clinical trial. Patients will be pregnant women in labor (dilation period) who want epidural anesthesia (EA), who will randomly receive 0.125% levobupivacaine (Group L) versus 0.2% ropivacaine (Group R). In both groups, controls of hemodynamic parameters and their relationship with changes in fetal heart rate (FHR) and cardiotocographic recording (RCTG) will be carried out during the first 60 minutes after the administration of the local anesthetic via the epidural route. In case of hypotension and/or subsequent FHR and RCTG alterations, they will also be recorded. The follow-up period will extend from the moment the patient enters the delivery room and requests epidural anesthesia until the moment the patient is discharged from the delivery room. The percentage of patients with hemodynamic alterations will be evaluated as a primary result, as well as the percentage of patients whose hemodynamic alterations are related to changes in FHR and RCTG, when using low doses of LA. In the following will also be evaluated in relation to analgesia, the onset time, level reached and degree of satisfaction; and various intra and postpartum side effects. DISCUSSION: Both groups of pregnant women in labor will be studied in order to obtain data on the potential impact of the use of low doses of local anesthetic via the epidural route on hemodynamic parameters and the state of well-being of the fetus.
The primary objective of this study is to investigate the impact of preoperative focused transthoracic ultrasound (FOCUS) on intraoperative hypotension and postoperative complications in hip fracture surgery. Our hypothesis is that a preoperative FOCUS along with a hemodynamic optimization protocol will reduce the occurrence of intraoperative drops in blood pressure and post-operative complications.
To evaluate the effect of ciprofol anesthesia Induction on hemodynamics in elderly patients undergoing elective noncardiac surgery，a prospective, randomized, controlled trial.
In this study, between 15 November 2022 - 15 November 2023, who met the inclusion and exclusion criteria, a total of 82 patients who are on the 2nd or 3rd day after the surgery and who are hospitalized in the cardiovascular surgery intensive care clinic will be recruited.
The aim of the study is to determine the correlation of the results of cardiac index (CI) measurements performed with use of bioreactance technology with the results of measurements made with the use of transpulmonary thermodilution. Both methods will be evaluated in reference to measurements based on echocardiography.
This study is designed as an observational study to collect Cardiospire cardiogenic oscillation signal (COS) and CO output parameters from the Pulmonary Artery Catheter in intubated patients.
The aim of the present work is to describe the hemodynamic effects shown in patients with ARDS secondary to SARS-CoV-2 infection
Hemodynamic unstability, defined by macrocirculation and/or microcirculation dysfunction or alteration is common in critically ill pediatric patients. The initial treatment of hemodynamically unstable patient is the fluid resuscitation (fluid challenge therapy). However, the stabilization of hemodynamics only with fluid resuscitation can be achieved in less than 50% pediatric patients. In case of persistent hypotension (defined as mean arterial pressure below 65 mmHg, or by the formula - 55 + 1,5 x age in years), or in case of persistent lactate levels and base deficit elevation is the catecholamine therapy method of choice in case of sufficiently restored intravascular volume. In adult patients, the drug of choice (the first line therapy of persistent hypotension) is considered norepinephrine (based on evidence-based data). The norepinephrine is administered intravenously in form of continuous infusion, with the dose adjusted to the target level of mean arterial pressure (MAP). It should be preferably administered through the central venous catheter to minimize the complications associated with the damage of the peripheral vein wall damage in case of administered into the peripheral vein. Due to lack of evidence-based data (EBM) for pediatric population, there is still significant heterogenity of clinical practice and dobutamin, dopamine, norepinephrine and epinephrine are being used for hemodynamically unstable pediatric patient.
Many surgical procedures are performed using the laparoscopic approach. However, insufflation of the abdomen (pneumoperitoneum) has detrimental hemodynamic effects. The investigators intend to investigate the effect of deep neuromuscular block and nociception guided anaesthesia on hemodynamic variables during pneumoperitoneum for lower abdominal laparoscopic surgery.
This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin ([HbO2]), deoxy-hemoglobin ([Hb]), the derived change in blood volume ([tHb]) and water concentration on the forehead of brain edema patients.
