“…5,6 The ability to measure absolute values of CI with a good accuracy and to track the direction of its changes during various clinical conditions were however less straightforward. [6][7][8] Lastly, PPV given by Nexfin has been found to correspond with the invasive reference method in the cardiac surgical setting. 9 Taken together, these results suggest that the Nexfin device could be used to conduct perioperative goaldirected therapy.…”

“…The NICOM is a bioreactance-based monitor that has been shown to perform similarly to the ED in guiding GDFT [38]. The Nexfin accurately and continuously measures both arterial blood pressure [39] and CO [40,41] using an inflatable finger cuff.…”

The underlying principles guiding fluid management in any setting are very simple: maintain central euvolemia, and avoid salt and water excess. However, these principles are frequently easier to state than to achieve. Evidence from recent literature suggests that avoidance of fluid excess is important, with excessive crystalloid use leading to perioperative weight gain and an increase in complications. A zero-balance approach aimed at avoiding fluid excess is recommended for all patients. For major surgery, there is a sizeable body of evidence that an individualized goal-directed fluid therapy (GDFT) improves outcomes. However, within an Enhanced Recovery program only a few studies have been published, yet so far GDFT has not achieved the same benefit. Balanced crystalloids are recommended for most patients. The use of colloids remains controversial; however, current evidence suggests they can be beneficial in intraoperative patients with objective evidence of hypovolemia.

“…In this study, we used the non-invasive Nexfin monitor for haemodynamic measurements. It measures continuous arterial blood pressure and subsequently calculates CO [5,13,[16][17][18][19][20][21][22] and PPV [5,11,13,23,24] from the arterial pressure waveform. It is restricted to patients with normal peripheral perfusion, and several studies have reported on its limited value in critically ill patients or during septic shock [25,26].…”

Detection of volume loss using the Nexfin device in blood donors

SummaryWe investigated which haemodynamic parameters derived from Nexfin non-invasive continuous arterial blood pressure measurements are optimal to detect controlled volume loss in spontaneously breathing subjects. Haemodynamic monitoring was performed in 40 whole-blood donors. Mean arterial pressure, cardiac index, systemic vascular resistance index and pulse pressure variation were recorded during controlled breathing, and a Valsalva manoeuvre was performed before and after blood donation. Blood donation resulted in a reduction in cardiac index (from 3.96 AE 0.84 l.min .m 2 ; p < 0.001) and an increase in pulse pressure variation (from 13.4 AE 5.1 to 15.3 AE 5.4%; p = 0.02). The area under the receiver operating characteristic curve to detect volume loss was highest for cardiac index (0.94, 95% CI 0.88-0.99) and systemic vascular resistance (0.90, 95% CI 0.82-0.99). Nexfin is a non-invasive haemodynamic monitor that can feasibly detect volaemic changes in spontaneously breathing subjects.
