Animal studies suggest that dynamic predictors remain useful in patients with pneumoperitoneum, but human data is conflicting. Our aim was to determine predictive values of pulse pressure variation (PPV) and stroke volume variation (SVV) in patients with pneumoperitoneum using LiDCORapid™ haemodynamic monitor. Standardised fluid challenges of colloid were administered to patients undergoing laparoscopic procedures, one fluid challenge per patient. Intra-abdominal pressure was automatically held at 12 mmHg...

OBJECTIVES: The prevalence of responsiveness to initial fluid challenge among hypotensive sepsis patients is unclear. To avoid fluid overload, and unnecessary treatment, it is important to differentiate these phenotypes. We aimed to 1) determine the proportion of hypotensive sepsis patients sustaining favorable hemodynamic response after initial fluid challenge, 2) determine demographic and clinical risk factors that predicted refractory hypotension, and 3) assess the association between timeliness of fluid resuscitation and refractoriness...

Arterial pulse pressure variation (PPV) is widely used for predicting fluid responsiveness and supporting fluid management in the operating room and intensive care unit. Available PPV algorithms have been typically validated for fluid responsiveness during episodes of hemodynamic stability. Yet, little is known about the performance of PPV algorithms during surgery, where fast changes of the blood pressure may affect the robustness of the presented PPV value. This work provides a comprehensive understanding of how various existing algorithmic designs affect the robustness of the presented PPV value during surgery, and proposes additional processing for the pulse pressure signal before calculating PPV...

BACKGROUND: The collapsibility index of the inferior vena cava is traditionally visualized from the subcostal region in the sagittal plane, referred to here as cIVCSS. Alternatively, the collapsibility index of the inferior vena cava can be visualized from the right midaxillary line in the coronal plane, referred to here as cIVCRC. It is unclear whether values of cIVCRC are comparable with values of cIVCSS because the inferior vena cava collapses asymmetrically into an elliptical form, quantified as the flat ratio of the inferior vena cava (F-IVC)...

BACKGROUND AND M&MS: Dynamic preload indices, such as systolic pressure variation (SPV), aortic flow peak velocity variation (ΔVpeak) and distensibility index of the caudal vena cava (CVCDI), are reliable indices for predicting fluid responsiveness in humans. This study aimed to investigate the ability of these indices to predict fluid response in 24 healthy dogs undergoing general anaesthesia and mechanical ventilation. Aortic flow peak velocity variation (∆Vpeak), CVCDI, and SPV were calculated before volume expansion (5mL/kg bolus of lactated Ringer's solution)...

BACKGROUND: Fluid administration in critically ill surgical patients must be closely monitored to avoid complications. Resuscitation guided by invasive methods are not consistently associated with improved outcomes. As such, there has been increased use of Focused Ultrasound and Arterial Pulse Waveform Analysis (APWA) to monitor and aid resuscitation. An assessment of these methods using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework is presented...

Spinal anaesthesia for elective caesarean section is associated with maternal hypotension, secondary to alteration of sympathetic tone and hypovolemia, in up to 70% of cases. Measurement of the subaortic variation in the velocity time integral (VTI) after passive leg raising allows prediction of fluid responsiveness. Our objective, in this prospective single-centre observational study, was to assess the ability of change in VTI after 45° passive leg raising to predict hypotension after spinal anaesthesia. Ultrasound measurements were performed just before elective caesarean section...

Background: During laparoscopic surgery in paediatric patients, sudden hypotension may occur following peritoneal desufflation due to hypovolaemia or an acute increase in gastrointestinal venous capacitance by the release of intra-abdominal pressure. This study examined whether dynamic variables of fluid responsiveness during pneumoperitoneum can predict the occurrence of hypotension following desufflation. Methods: A total of 120 paediatric subjects were prospectively enrolled...

Background: Pulse pressure variation (PPV) is widely used as a predictor of fluid responsiveness. However, a previous study has suggested a 'grey zone' between 9 and 13% in which PPV would be inconclusive to predict fluid responsiveness. Considering PPV is based on cardiopulmonary interactions, we evaluated whether an augmented PPV using a temporary increase in tidal volume (V T ) from 8 to 12 ml kg -1 has the predictability for fluid responsiveness in patients within the grey zone...

BACKGROUND: Arterial blood pressure is the most common variable used to assess the response to a fluid challenge in routine clinical practice. The aim of this study was to evaluate the accuracy of the change in the radial artery pulse pressure (rPP) to detect the change in cardiac output after a fluid challenge in patients with septic shock. METHODS: Prospective observational study including 35 patients with septic shock in which rPP and cardiac output were measured before and after a fluid challenge with 400 mL of crystalloid solution...

REVIEW
Victoria A Bennett, Maurizio Cecconi
Perioperative fluid management is a key component in the care of the surgical patient. It is an area that has seen significant changes and developments, however there remains a wide disparity in practice between clinicians. Historically, patients received large volumes of intravenous fluids perioperatively. The concept of goal directed therapy was then introduced, with the early studies showing significant improvements in morbidity and mortality. The current focus is on fluid therapy guided by an individual patient's physiology...

OBJECTIVE: Static monitors for assessing the fluid status during major surgeries and in critically ill patients have been gradually replaced by more accurate dynamic monitors in modern-day anaesthesia practice. Pulse pressure variation (PPV) and systolic pressure variation (SPV) are the two commonly used dynamic indices for assessing fluid responsiveness. METHODS: In this prospective observational study, 50 patients undergoing major surgeries were monitored for PPV and SPV: after the induction of anaesthesia and after the administration of 500 mL of isotonic crystalloid bolus...

COMPARATIVE STUDY
Ahmad Elgendy, Ian M Seppelt, Andrew S Lane
BACKGROUND: Continuous-wave Doppler (CWD) ultrasound through the left ventricular outflow tract is one modality used for non-invasive cardiac output measurement. The ultrasonic cardiac output monitor (USCOM) is a relatively new monitor which uses a small, transcutaneous ultrasound probe to measure cardiac output with CWD via the suprasternal window. It is faster and less complex to train new users than conventional echocardiography. In addition to stroke volume (SV), the USCOM can calculate stroke volume variation (SVV) and the Smith-Madigan inotropy index (SMII), which is an estimate of the pre-load independent contractility of the myocardium...

OBJECTIVES: First, we aimed at assessing whether fluid responsiveness is predicted by the effects of an end-expiratory occlusion on the velocity-time integral of the left ventricular outflow tract. Second, we investigated whether adding the effects of an end-inspiratory occlusion and of an end-expiratory occlusion on velocity-time integral can predict fluid responsiveness with similar reliability than end-expiratory occlusion alone but with a higher threshold, which might be more compatible with the precision of echocardiography...

BACKGROUND: Pulse pressure variation derived from the varied pulse contour method is based on heart-lung interaction during mechanical ventilation. It has been shown that pulse pressure variation is predictive of fluid responsiveness in children undergoing surgical repair of ventricular septal defect. Right ventricle compliance and pulmonary vascular capacitance in children with tetralogy of Fallot are underdeveloped as compared to those in ventricular septal defect. We hypothesized that the difference in the right ventricle-pulmonary circulation in the two groups of children would affect the heart-lung interaction and therefore pulse pressure variation predictivity of fluid responsiveness following cardiac surgery...
