[Implementation of fast-track measures in colorectal resections : A survey among members of the DGAI]

PURPOSE

The fast-track (FT) concept is a multimodal, interdisciplinary approach to perioperative patient care intended to reduce postoperative complications. Despite good evidence implementation seems to need improvement, whereby almost all studies focused on the implementation of surgical modules regardless of the interdisciplinary aspect. Adherence to the anesthesiological measures (prehabilitation, premedication, volume and temperature management, pain therapy), on the other hand, has been insufficiently studied. To assess the status quo a survey on the implementation of anesthesiological FT measures was conducted among members of the German Society of Anesthesiology and Intensive Care Medicine (DGAI) to analyze where potential for improvement exists.

METHODS

Using the SurveyMonkey® online survey tool, 28 questions regarding perioperative anesthesiological care of colorectal surgery patients were sent to DGAI members in order to analyze adherence to FT measures.

RESULTS

While some of the FT measures (temperature management, PONV prophylaxis) are already routinely used, there is a divergence between current recommendations and clinical implementation for other components. In addition to premedication, interdisciplinary measures (prehabilitation) and measures that affect multiple interfaces (operating theatre, recovery room, ward), such as volume management or perioperative pain management, are particularly affected.

CONCLUSION

The anesthesiological recommendations of the FT concept are only partially implemented in Germany. This particularly affects the interdisciplinary components as well as measures at the operating theatre, recovery room and ward interfaces. The establishment of an interdisciplinary FT team and interdisciplinary development of SOPs can optimize adherence, which in turn improves the short-term and long-term outcome of patients.

Is internal jugular vein extensibility associated with indices of fluid responsiveness in ventilated patients?

BACKGROUND

Ultrasound of the inferior vena cava provides rapid and non-invasive assessment of fluid responsiveness. We hypothesized that the extensibility of the internal jugular vein (IJV) as well reflects intravascular volume state. We assessed IJV dimensions together with pulse pressure variation (PPV) as dynamic index for fluid responsiveness in mechanically ventilated patients.

METHODS

Of 50 patients after cardiac surgery were assessed. Ultrasound of IJV dimensions as well as collection of hemodynamic data were performed in 30° and horizontal (0°) position, and the ventilator- and position-induced IJV extensibilities (E-IJV) were calculated.

RESULTS

Mean ventilator-induced E-IJV in 30° position was 56%, and mean PPV in 30° position was 13.7%. Changing the patient's position from 30° to 0° significantly reduced ventilator-induced E-IJV as well as PPV. Pearson's correlation test revealed significant association between ventilator-induced E-IJV and fluid responsiveness deduced from PPV in 0° position (r = 0.43, P < 0.005). An E-IJV threshold >5% identified patients with significantly elevated PPV values.

CONCLUSION

Ultrasound of the IJV and PPV as a dynamic index for fluid responsiveness can be associated under certain defined conditions. Whether or not ultrasound of the IJV can be useful to predict patient intravascular volume state should be further studied using invasive cardiac output monitoring.
