Pediatric Moyamoya Revascularization Perioperative Care: A Modified Delphi Study
ConclusionsIn the absence of data supporting specific care practices before and after indirect revascularization surgery in children with moyamoya, this Delphi process defined areas of consensus among neurosurgeons, neurologists, and intensivists with moyamoya expertise. Research priorities identified include determining the role of continuous electroencephalography in postoperative moyamoya care, optimal perioperative blood pressure and hemoglobin targets, and the role of supplemental oxygen for treatment of suspected postoperative ischemia.

E-009 Initial experience of curative transvenous embolization of cerebral arteriovenous malformations using rapid ventricular pacing for flow arrest
ConclusionRVP may be successfully used to obtain flow arrest during neuroendovascular procedures, particularly those that require precise and controllable delivery of embolic material. This is a highly effective technique for curative transvenous embolization of cerebral AVMs in carefully selected patients, particularly those with AVMs that are small, with a single draining vein, and unresectable due to deep location (SM grade III or less). These preliminary results highlight the need for future studies to validate efficacy and optimize patient selection.Disclosures A. White: None. J. Corona: None. R. Joshi: None. B. Welch...

Practical impact of a decision support for goal-directed fluid therapy on protocol adherence: a clinical implementation study in patients undergoing major abdominal surgery
AbstractThe purpose of this study was to assess the effects of using a real time clinical decision-support system, “Assisted Fluid Management” (AFM), to guide goal-directed fluid therapy (GDFT) during major abdominal surgery. We compared a group of patients managed using the AFM system with a historical cohort of patients (control group) who had been managed using a manual GDFT strategy. Adherence to the pro tocol was defined as the relative intraoperative time spent with a stroke volume variation (SVV) < 13%. We hypothesised that patients in the AFM group would have more time during surgery with a SVV < ...

Debilitating Headache after an Excited Reaction
BY GREGORY TAYLOR, DO, & MATTHEW WARPINSKI, DOA 35-year-old man with a history of uncontrolled hypertension and medical noncompliance was brought to the emergency department by EMS complaining of a headache. The family said the patient was watching football and developed an acute headache after he stood up screaming in excitement.His family said he had not taken his blood pressure medication for years. He was afebrile, his blood pressure was 245/129 mm Hg, his respiratory rate was 18 bpm, his heart rate was 68 bpm, and he weighed 340 pounds. The patient was obtunded with a Glasgow Coma Scale score of 4 and was subse...

Comparing Changes in Carotid Flow Time and Stroke Volume Induced by Passive Leg Raising.
CONCLUSIONS: CFTC performs well compared to stroke volume measurements on a Vigileo monitor. The use of CFTC is highlighted in resource-limited environments and when time limits the use of other methods. CFTc should be validated in a larger study with more operators against a variety of hemodynamic monitors.

Automated, continuous and non-invasive assessment of pulse pressure variations using CNAP ® system
Abstract
Non-invasive respiratory variations in arterial pulse pressure using infrared-plethysmography (PPVCNAP) are able to predict fluid responsiveness in mechanically ventilated patients. However, they cannot be continuously monitored. The present study evaluated a new algorithm allowing continuous measurements of PPVCNAP (PPVCNAPauto) (CNSystem, Graz, Austria). Thirty-five patients undergoing vascular surgery were studied after induction of general anaesthesia. Stroke volume was measured using the VigileoTM/FloTracTM. Invasive pulse pressure variations were manually calculated using an arterial line (PPVART) a...

Effects of adrenaline on circulatory dynamics and cardiac function in rats administered chlorpromazine
Abstract
We aimed to elucidate changes in circulatory dynamics and cardiac function during concomitant use of chlorpromazine (CPZ) and adrenaline (AD). An arterial line and left intraventricular pressure–volume measurement catheter were inserted in rats. CPZ 10 mg/kg was administered to the left great adductor muscle, followed by normal saline (NS) or AD 50 μg/kg through the tongue 20 min later. End-diastolic volume (V
ed), end-systolic pressure (P
es), stroke volume (SV), stroke work (SW), end-systolic volume elastance (E
es), systolic blood pressure (SBP), diastoli...

Stroke volume variation to guide fluid therapy: is it suitable for high-risk surgical patients? A terminated randomized controlled trial
Conclusions
Our study was stopped due to a slow inclusion rate. Methodological restrictions of the arterial-line cardiac output monitor excluded the majority of patients. This leaves the question if this method is appropriate to guide fluid therapy in high-risk surgical patients.

Dynamic arterial elastance as a predictor of arterial pressure response to fluid administration: a validation study
IntroductionFunctional assessment of arterial load by dynamic arterial elastance (Eadyn), defined as the ratio between pulse-pressure variation (PPV) and stroke volume variation (SVV), has recently been shown to predict the arterial pressure response to volume expansion (VE) in hypotensive preload-dependent patients. However, since both SVV and PPV were obtained from pulse-pressure analysis, a mathematical coupling factor could not be excluded. We therefore designed this study to confirm whether Eadyn, obtained from two independent signals, allows the prediction of arterial pressure response to VE in fluid-responsive patie...

Temporary right ventricular support following left ventricle assist device implantation: a comparison of two techniques
CONCLUSIONS
Temporary support of the failing RV after LVAD implantation using temporary vein and the pulmonary artery RVAD is a promising therapeutic option. This approach provides adequate LVAD pre- and afterload and is associated with significantly less thromboembolic complications.

Upper thoracic epidural anaesthesia: effects of age on neural blockade and cardiovascular parameters
ConclusionWe were unable to demonstrate an effect of age on the maximal number of spinal segments blocked after TEA; however, the caudad spread of analgesia increased with advancing age. In addition, reduction of heart rate was greater in the youngest group.
