Maternal hypotension is a common complication after spinal anaesthesia for caesarean delivery. Prophylaxis against post-spinal hypotension (PSH) during caesarean delivery would prevent serious maternal and fetal complications. Various methods had been investigated for prophylaxis against maternal hypotension. The basic components of management of PSH are: 1. Fluid loading. 2. Pharmacological agents. 3. Positioning protocols. Although Fluid loading is superior to non-loading protocols during caesarean delivery, the incidence of Post-spinal hypotension is high with all fluid loading protocols. Thus; the value of fluid loading in caesarean delivery could not be used solely for prevention of PSH. Using vasopressors for prophylaxis against PSH is nearly fundamental during caesarean delivery. However, vasopressors are not devoid of side effects such as reflex bradycardia after phenylephrine and fetal acidosis after ephedrine. Thus, combining vasopressor prophylaxis and non-pharmacological protocols would help to decrease the dose of vasopressors, and consequently decreasing their side effects. Ondansetron had been also reported as a useful prophylactic drug from PSH with minimal side effects. Positioning protocols, such as operating table tilting or flexing, the use of wedges or mechanical displacers, leg wrapping or sequential compression devices, head down and head up positioning aim to reversing aortocaval compression and/or increasing venous return. The sitting position for a short period after spinal block in order to slow the onset of the spinal block. Keeping the patient in the sitting position after spinal block would also prevent extension of local anaesthetic solution to upper thoracic dermatomes which is an important factor in preventing maternal hypotension. no previous reports had evaluated the impact of sitting position within the context of a multimodal protocol for prophylaxis against maternal hypotension. In this study, we aim to evaluate the impact of 2-minute sitting position after spinal anesthesia on maternal hemodynamics when combined with prophylactic norepinephrine infusion plus preoperative bolus of ondansetron. We aim to reach the best possible maternal hemodynamic profile in addition to maintenance of adequate block level.
This study aims to compare the volume management methods performed by using conventional method and PVI monitoring in intraoperative fluid treatment during bilateral salpingo-oophorectomy and total hysterectomy operation.
Up to today, inadequate evidences and knowledge exist about the best prehospital management of hypotensive trauma patients and its clinical consequence on the in-hospital recovery and mortality. Also new emerging therapies such as prehospital blood transfusion and REBOA (resuscitative endovascular balloon occlusion of the aorta) are lacking strong evidences in, eventually, reducing hospital mortality and improving outcomes. Moreover, prehospital emergency medicine is throughout Italy an heterogeneous system that has no unique standard operating procedures and, even among HEMS (helicopter emergency medical service), management and therapies on complex trauma patients may vary upon local policies. With this study we aim to enroll hypotensive trauma patients and study factors of prehospital rescue that can be associated with in-hospital mortality and recovery, eventually even with hospital outcome. For each patients data as demographic, kind of trauma (mechanism, injury scores), therapies and maneuvers will be recorded and then analyzed in comparison with in-hospital data such as need for transfusion, ABG parameters, length of stay (in-ward and ICU), need of therapies like invasive ventilation and renal replacement therapy, recovery and outcome
Noninvasive continuous blood pressure monitoring for preventing post-spinal hypotension during cesarean delivery: A randomized controlled trial
The goal of this study is to determine whether the use of sequential compression devices (lower limb compression) can reduce the rate of maternal hypotension after epidural, and therefore reduce the incidence of fetal heart tracing complications during labor.
This is a randomized trial (1) investigating whether continuous non-invasive finger-cuff blood pressure monitoring reduces the area under a mean arterial pressure (MAP) of 65 mmHg within the first 15 minutes of anesthetic induction compared to intermittent blood pressure monitoring using upper-arm cuff oscillometry in patients having non-cardiac surgery; and (2) investigating whether continuous non-invasive finger-cuff blood pressure monitoring reduces the time-weighted average for MAP <65 mmHg during the intraoperative period compared to intermittent blood pressure monitoring using upper-arm cuff oscillometry in patients having non-cardiac surgery.
Hypotension is common during spinal anesthesia and contributes to underperfusion and ischemia. Severe episodes of intraoperative hypotension is an independent risk factor for myocardial infarction, stroke, heart failure, acute kidney injury, prolonged hospital stay and increased one year mortality rates. Empiric fluid preloading can be done to decrease the incidence of hypotension but carries risk of fluid overload especially in elderly and cardiac patients. Inferior venacava ultrasonography (IVC USG) has been used in spontaneously breathing critically ill patients for volume responsiveness but there is limited data regarding its use for volume optimization in perioperative setting. The aim of this study is to evaluate the use of inferior venacava ultrasound to guide fluid management for prevention of hypotension after spinal anesthesia.
Evaluation of a novel mobile application designed to estimate blood pressure (systolic-diastolic and mean arterial pressure) based on collected optical signals on patient's finger treated in intensive care unit patients
Study objectives: To determine whether, in critically ill patients with Acute Kidney Injury requiring renal replacement therapy (AKI-RRT), randomization to receive intravenous hyperoncotic albumin 20-25% (100 mL X two doses) compared to control/placebo normal saline boluses (100 mL X two doses) given during RRT sessions, leads to: 1. An increase in organ support-free days (primary outcome) at 28 days following randomization; and 2. An increase in RRT-free days (principal secondary outcome) at 28 days following randomization.
