Fasting ≥6 h does not alter preload indices in ASA 1-2 volunteers; hypothesis-generating and leaves open effects in surgical or higher-risk patients.
Does a fasting period of at least 6 hours alter preload responsiveness in ASA 1 and 2 volunteers?
Fasting for at least 6 hours does not significantly alter preload or position on the Frank-Starling curve in conscious ASA 1 and 2 volunteers.
