Patients undergoing mechanical ventilation and receiving nutrition via a feeding tube who did not receive monitoring of residual gastric volume (amount of liquid left in the stomach after use of feeding tube) were not at a significantly greater risk of developing ventilator-associated pneumonia, according to a study appearing in the Jan. 16 issue of JAMA. There is concern that monitoring of residual gastric volume leads to unnecessary interruptions of use of the feeding tube and subsequent inadequate feeding.
