Table 2 Techniques for delivery of feeds in enteral tube feeding
Method of feedingIndicationComments
Bolus intermittent (by syringe or bulb)Ambulatory patients100-400 mL over 5-10 min multiple times, high risk of aspiration and diarrhea, cheap and convenient for NGT
Cyclic intermittent (by gravity or pump)Partially recumbentHigher infusion rate for a shorter period (8-16 h); while changing from tube feeds to oral
Intermittent dripHome enteral feeding1.5-2 L over 8-12 h overnight, no daytime feeds
(by gravity or pump)
Constant infusion (by gravity or pump)Bedridden patients ICU patientsInitiate with 20-50 mL/h, altered periodically depending on gastric residual volume, increased chances of aspiration and metabolic abnormalities; incline head end of bed to 45° to reduce aspiration and regurgitation
