Abstract:
Objective Acute gastrointestinal dysfunction (AGD) is a common problem in critically ill patients, for whomearly enteral nutrition ( EN) is widely used, but its application dosage remains controversial.This study aimed to observe the influence of dif-ferent doses of early EN on acute gastrointestinal tolerance, new infections and other complications, inflammation indexes, and prognosis in AGD patients. Methods We selected 120 critically ill patients that met thecriteria of class-ⅡAGD and needed EN support andequal-ly randomized them intoa standard-dose and a low-dose ENgroup.The former group received EN at 20 mL/h, with an addition of 10 mL/h every 12 hours according to the tolerance and supplemented byparenteral nutrition (PN) to achieve the target calories(60%) on the 3 rd day, while the latterat 20 mL/h for 7 days, supplemented by PN to achieve the target calories on the 3 rd day and from the 7 th day gradu-ally increased to the full volume.We recorded the patients′ICUdays, hospitaldays, mortality rate, organ function support days, incidence of feeding intolerance within 7 days, incidence of new infections within 7 and 28 days, and levels of C-reactive protein (CRP), procalci-tonin (PCT), tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) and compared these indexes between the two groups. Resulst There were no statistically significant differences between the low -and standardd-ose EN groups in the patients′ICU days, hospital days, mortality rate,organ function support days, or incidence of new infections within 7 and 28 days ( P>0.05) .The incidence of feeding intol-erance on the 7 th day was significantly lower in the low-dose than in the standard-dose EN group ( 13.3 vs 36.7%, P<0.05).On the 1st, 3rd, and 7 th day, the level of CRP was (5.90±0.72), (16.52± 3.09) , and ( 32.11 ±4.33 ) ng/L, respectively, in the low-dose groupversus(5.83±0.59), (15.83±1.19), and (33.16±4.51)ng/L in the standard-dose group, while that of PCTwas (4.71±1.25), (10.63± 2.21), and ( 16.89±3.39) ng/mL, respectively, in the former versus (4.55±0.67), (10.41±1.99), and (17.49±3.87)ng/mL in the latter, both increased in a time-dependent manner and with significant differ-ences among the three time points within the same group ( P<0.05) .The levels of TNF-αand IL-6 were elevated in the same manner and also with significant differences among the three time points within the same group ( P<0 .05) . Conc lusion Lowdose of early enteral nutrition can improve the feeding tolerance of AGDpatients, but does not influence the incidence of new infections and prognosis.
