NCT07486167
The goal of this randomized interventional clinical trial is to learn if a standardized lung volume optimization maneuver (LVOM) is beneficial in children undergoing biventricular repair of their congenital heart disease (CHD) with cardiopulmonary bypass. Main hypotheses: Does a standardized PEEP-Titration maneuver, to optimize end-expiratory lung volume improve: * cardiac performance * lung function Does it make a difference in: * length of ventilation * ventilation/perfusion mismatch of the lung * need for vasopressor support?
NCT07322562
Music therapy has been reported to reduce analgesic and anesthetic requirements, but evidence in thoracic surgery remains limited. This prospective observational study aimed to evaluate the effects of different music types on hemodynamic stability and anesthetic consumption in patients undergoing thoracic surgery.
NCT07054138
This study aims to evaluate the effect of preoperative dexmedetomidine nebulization on blunting hemodynamic response for laryngoscope, intubation, pneumoperitoneum, and opioid consumption in morbidly obese patients undergoing laparoscopic bariatric surgery.
NCT07259551
Purpose of the Observational Study: The purpose of this observational study was to evaluate the effects of the palmar technique on preoperative anxiety, hemodynamic parameters, and intubation-related hemodynamic responses in patients undergoing thyroidectomy. Primary Research Question: Does the palmar technique applied preoperatively reduce preoperative anxiety and associated hemodynamic changes in thyroidectomy patients? Study Design: Type: Prospective, single-blind, observational study Location: A single-center tertiary care hospital in Turkey Sample: 80 patients aged 18-65, ASA I-II Methods: Patients were divided into two groups using a sealed envelope method: Group P: Patients who received the palm-based technique Group N: Control group without intervention When admitted to the preoperative waiting room (T1), all patients: Baseline vital signs (SpO₂, heart rate, blood pressure) State-Trait Anxiety Inventory (STAI) scores were recorded. Patients in Group P received the palm-based technique; Group N received no intervention. The same parameters were measured again 15 minutes later (T2). After transfer to the operating room, standard monitoring was performed, and hemodynamic data were recorded at the following times: Pre-intubation (T3) 1 min (T4), 3 min (T5), 5 min (T6), and 10 min (T7) after intubation Main Outcome Measures: Changes in preoperative anxiety level Changes in hemodynamic parameters after the palmar technique Sample Size:Total: 80 patients
NCT07109232
This prospective study aims to evaluate the hemodynamic effects of different surgical positions-supine, lithotomy, and prone-in patients undergoing percutaneous nephrolithotomy (PCNL). Hemodynamic parameters are assessed using the Pressure Recording Analytical Method (PRAM) both while patients are awake and under general anesthesia. The study investigates how positioning-independently and in combination with anesthesia-influences cardiovascular function, including mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SVI), pulse pressure variation (PPV), stroke volume variation (SVV), cardiac contractility parameters (dP/dtmax), arterial elastance (Ea), cardiac power index (CPI), and cardiac cycle efficiency (CCE). The findings are expected to contribute to optimizing perioperative management and enhancing patient safety during PCNL procedures.
NCT07037225
The aim of this trial is to study the changes of the Cardiac Power Index (CPI) during supine and lateral decubitus position in two and one lung ventilation respectively. Moreover, CPI variations will be compared among patients in left versus patients in right lateral decubitus position. A secondary goal is to compare the changes in hemodynamic parameters after a lung recruitment maneuver during one lung ventilation and a fluid challenge test among patients that respond (responders) or do not respond to fluids (non-responders) according to changes of Stroke Volume Index (SVI) and Mean Arterial Pressure (MAP).
NCT06909396
The aim of this work was to assess stress response and hemodynamic changes associated with intrathecal anesthesia versus caudal epidural anesthesia in infants undergoing laparoscopic inguinal herniorrhaphy.
NCT05619809
This study is a randomized, double-blind, placebo-controlled trial. Healthy, exercising adult males and females will be recruited for participation. After providing informed consent, each participant will be randomized to one of three groups: 1) OxyShred thermogenic fat burner; 2) Placebo (PL); and 3) Control. All participants will complete a baseline laboratory visit consisting of assessments of body composition, anthropometry, metabolism, hemodynamics, dietary intake, exercise habits, and subjective variables. Participants in the two intervention groups (i.e., OxyShred and PL) will then be given dietary supplements for daily consumption, including OxyShred/PL and protein powder. Participants in all groups will complete the 4-week study and follow their usual training and nutrition habits - besides increased protein intake in the OxyShred and PL groups - along with questionnaires to assess compliance with the study protocol and potential side effects of supplementation. Following this 4-week period, participants will complete a second laboratory visit, where all baseline assessments will be repeated. The effects of group (OxyShred, PL, and control) and time (baseline, 4 weeks) will be statistically examined using linear models, along with appropriate post-hoc tests.
NCT01861132
Blood pressure and cardiac output can be measured invasively in pregnant women. Non-invasive monitoring devices are desirable, but until now, no equipment has proven validity. This study aims at validating the non-invasive monitoring device NexFin (second generation Finometer) in pregnant women.
NCT01186549
Objectives: Injection pain and hypotension are two main adverse effects of propofol which distresses patient. The aim of this prospective double blind study was to compare the effect of ephedrine -lidocaine combination with lidocaine and ephedrine on injection pain and hemodynamic changes due to propofol induction. Methods: 165 adult patients, aged 20 to 60 yr, Patients were randomly allocated to one of 5 groups (33 patients per group): lidocaine 0.5 mg/kg(L) ,ephedrine 30microgram/kg (E30), ephedrine 70 microgram/kg(E70), lidocaine 0.5mg/kg -ephedrine 30 microgram/kg(LE) or 2ml saline (S) intravenously. After one minute propofol 2 mg/kg into a dorsal hand vein was injected. Face pain scale and verbal rating scale, arterial blood pressure and heart rate were recorded before induction, just before intubation, and one minute after intubation
