Abstract

Objective

Intraoperative haemodynamic optimization based on fluid management and stroke volume optimization (Goal Directed Fluid Therapy [GDFT]) can improve patients’ postoperative outcome. We have described a closed-loop fluid management system based on stroke volume variation and stroke volume monitoring. The goal of this system is to apply GDFT protocols automatically. After conducting simulation, engineering, and animal studies the present report describes the first use of this system in the clinical setting.

Study design

Prospective pilot study.

Patients

Patients undergoing major surgery.

Methods

Twelve patients at two institutions had intraoperative GDFT delivered by closed-loop controller under the direction of an anaesthesiologist. Compliance with GDFT management was defined as acceptable when a patient spent more than 85% of the surgery time in a preload independent state (defined as stroke volume variation<13%), or when average cardiac index during the case was superior or equal to 2.5l/min/m2.

Results

Closed-loop GDFT was completed in 12 patients. Median surgery time was 447 [309–483] min and blood loss was 200 [100–1000] ml. Average cardiac index was 3.2±0.8l/min/m2 and on average patients spent 91% (76 to 100%) of the surgery time in a preload independent state. Twelve of 12 patients met the criteria for compliance with intraoperative GDFT management.

Conclusion

Intraoperative GDFT delivered by closed-loop system under anaesthesiologist guidance allowed to obtain targeted objectives in 91% of surgery time. This approach may provide a way to ensure consistent high-quality delivery of fluid administration and compliance with perioperative goal directed therapy.

Résumé

Objectif

L’optimisation hémodynamique peropératoire basée sur l’optimisation du remplissage vasculaire permet d’améliorer la morbi-mortalité postopératoire au cours d’une chirurgie majeure. Nous avons décrit un système permettant d’appliquer ce concept en boucle fermée et sur la base de l’optimisation du volume d’éjection systolique et d’indices de précharge dépendance. Cette étude présente la première utilisation de ce système en clinique.

Type d’étude

Étude pilote prospective.

Patients

Douze patients au cours d’une chirurgie majeure.

Méthodes

L’administration du remplissage vasculaire était automatisée, basée sur l’optimisation de l’index cardiaque (IC) et d’indices de précharge dépendance (variation du volume d’éjection systolique [VVE]<13 %) et sous la surveillance de l’anesthésiste en charge du patient. L’objectif d’optimisation était jugé atteint si le patient passait plus de 85 % du temps de la chirurgie en condition de précharge indépendance (VVE<13 %) ou quand l’IC moyen au cours de la chirurgie était supérieur à 2,5L/min/m2.

Résultats

L’optimisation était atteinte en boucle fermée sans intervention de l’anesthésiste chez les 12 patients. La durée médiane de la chirurgie était de 447 [309–483] minutes et les pertes sanguines médianes étaient de 200 [100–1000] mL. L’index cardiaque moyen était de 3,2±0,8L/min/m2 et en moyenne les patients passaient 91 % (76 à 100 %) du temps en condition de précharge indépendance.

Conclusion

L’optimisation du remplissage vasculaire en boucle fermée et basée sur l’optimisation du débit cardiaque et des indices de précharge dépendance permet une obtention des objectifs hémodynamiques pendant en moyenne 91 % du temps chirurgical.
