Usefulness of stroke volume variation to assess blood volume during blood removal for autologous blood transfusion in pediatric patients
ConclusionStroke volume variation obtained from the FloTrac/VigileoTM monitoring system revealed a strong correlation with EBV during ANH without surgical stimulation. The usefulness of this device as an indicator of cardiac preload under hypovolemic or normovolemic conditions in children during surgery remains to be determined.

Outcomes associated with stroke volume variation versus central venous pressure guided fluid replacements during major abdominal surgery
Conclusion: Implementation of fluid replacement guided by a dynamic preload variable (SVV) versus conventional static variables (CVP) is associated with lesser postoperative ICU stay and reduced fluid requirements in major abdominal surgery.

Perioperative stroke following TURP: high index of suspicion and stabilization of physiological parameters can save lives
We report a case of a 72 year old hypertensive male who developed severe hypertension followed by neurological deterioration in the immediate postoperative period after TURP. While arterial blood gas and laboratory tests excluded TURP syndrome or any other metabolic cause, reduction of blood pressure failed to ameliorate the symptoms. A cranial CT done 4h after the onset of neurological symptoms revealed bilateral gangliocapsular and right thalamic infarcts. Oral aspirin was advised to prevent early recurrent stroke. Supportive treatment and mechanical ventilation ensured physiological stability and the patient recovered c...

Predicting stroke volume and arterial pressure fluid responsiveness in liver cirrhosis patients using dynamic preload variables: A prospective study of diagnostic accuracy
The objective was to evaluate SV and arterial pressure fluid responsiveness in liver cirrhosis patients by using dynamic preload and vascular tone variables.
DESIGN: A prospective study of diagnostic accuracy.
SETTINGS: A single-centre trial conducted from November 2013 to April 2015.
PATIENTS: Thirty-one adult patients, recipients of a living donor liver transplantat.
INTERVENTION: An intraoperative fluid challenge with 10 ml kg−1 of 0.9% normal saline.
MAIN OUTCOME MEASURES: PPV, SVV, cardiac index and systemic vascular resistance index were measured using the Pulse index Continuous cardiac system. The PVI and...

Disagreement between fourth generation FloTrac and LiDCOrapid measurements of cardiac output and stroke volume variation during laparoscopic colectomy
To determine the agreement between cardiac output (CO) and stroke volume variation (SVV) measured simultaneously by the fourth generation FloTrac/Vigileo system and LiDCOrapid system during pneumoperitoneum in patients undergoing laparoscopic colectomy.

The management of haemorrhagic stroke
Publication date: Available online 26 October 2016 Source:Anaesthesia & Intensive Care Medicine Author(s): Robin S. Howard Intracerebral haemorrhage (ICH) accounts for 8–13% of all strokes and results from a variety of disorders. ICH is more likely to result in death or major disability than ischaemic stroke or subarachnoid haemorrhage. Rapid imaging allows early diagnosis and characterization of the localization and severity of the haemorrhage. Patients with acute ICH should be managed in an intensive care unit. Treatment entails general supportive care, control of blood pressure (BP) and intracranial pressure ...

Electrical impedance tomography for non-invasive assessment of stroke volume variation in health and experimental lung injury
Conclusions. EIT provides automated calculation of a dynamic preload index of fluid responsiveness (SVVEIT) that is non-invasively derived from a central haemodynamic signal. However, alterations in thoracic impedance induced by lung injury influence this method.

Can the descending aortic stroke volume be estimated by transesophageal descending aortic photoplethysmography?
ConclusionsThe AC and AUC extracted from the dPPG signal provided a sensitive and qualitative prediction for dSV level. The dSV value could not be accurately measured by dPPG metrics.Trial Registration Chinese Clinical Trials Register Identifier: ChiCTR-OCS-12002789.

Comparison of stroke volume measurement between non-invasive bioreactance and esophageal Doppler in patients undergoing major abdominal –pelvic surgery
ConclusionsIn patients undergoing major abdomino-pelvic surgery, SV values obtained by NICOM showed neither clinically or statistically acceptable agreement with those obtained by esophageal Doppler. Although, in the setting of this study, bioreactance technology cannot reliably replace esophageal Doppler monitoring, its accuracy for predicting fluid responsiveness was higher, up to approximately 80%.Trial registrationObservational study.

Anaesthesia practices for endovascular therapy of acute ischaemic stroke: a Nordic survey
ConclusionsThis survey indicates that the majority of Nordic anaesthesia departments who manage anaesthesia for EVT are able to provide immediate 24‐h response to an EVT request. Most of these departments have institutional guidelines for EVT anaesthesia and haemodynamic management. Conscious sedation appears to be the preferred method of anaesthetic care.

Anesthetic Management of Mitochondrial Encephalopathy With Lactic Acidosis and Stroke-Like Episodes (MELAS Syndrome) in a High-Risk Pregnancy: A Case Report
We present the in-hospital course of a 36-year-old gravida 2, para 0 with MELAS syndrome and severe preeclampsia, complicated by hyponatremia, hyperkalemia, and diabetes. A retained placenta with postpartum hemorrhage required urgent instrumental delivery under spinal anesthesia, transfusion, and intensive care unit admission for pulmonary edema, effusions, and atelectasis. Postpartum endometritis and sepsis also were encountered. This is to our knowledge the first case report of obstetric complications in MELAS syndrome and highlights the salient metabolic sequelae of this syndrome.

Comparison of two stroke volume variation-based goal-directed fluid therapies for supratentorial brain tumour resection: a randomized controlled trial
ConclusionsDuring GDFT for supratentorial brain tumour resection, fluid boluses targeting a lower SVV are more beneficial than a restrictive protocol.Clinical trial registrationNCT02113358.
