摘  要:目的探讨深度水解蛋白配方奶(e HPF)对极低出生体重(VLBW)早产儿肠系膜上动脉(SMA)血流的影响。方法选择2011年3月至2015年3月我院新生儿重症监护病房收治的VLBW早产儿,随机分为e HPF组及早产儿配方奶喂养组(PF组)。e HPF组以e HPF开奶,喂养至生后14天换PF;PF组直接以PF开奶。彩色多普勒超声检测患儿生后第1、7、14天空腹及第14天餐后30 min SMA血流,进行两组间比较。结果 (1)共纳入64例VLBW早产儿,其中e HPF组30例,PF组34例。e HPF组生后第7天[(41.8±30.3)ml/kg比(21.9±19.2)ml/kg]、第14天[(97.8±43.0)ml/kg比(76.0±39.0)ml/kg]喂养量明显高于PF组,达全肠道喂养时间明显短于PF组[(18.5±9.2)天比(23.0±8.5)天],差异有统计学意义(P<0.05)。(2)两组患儿生后第1、7天空腹状态下SMA收缩期峰流速(PSV)、舒张末期流速(EDV)、时间平均流速(TAMV)、阻力指数(RI)差异均无统计学意义(P>0.05);第14天空腹状态下e HPF组PSV[(95.7±20.9)cm/s比(82.8±20.5)cm/s]、EDV[(19.3±6.6)cm/s比(15.8±6.5)cm/s]、TAMV[(42.3±11.6)cm/s比(36.7±10.4)cm/s]高于PF组,差异有统计学意义(P<0.05)。(3)两组患儿生后第14天餐后30 min SMA PSV、EDV、TAMV均较餐前增高,RI较餐前降低。e HPF组PSV[(115.0±18.3)cm/s比(100.6±23.1)cm/s]、EDV[(29.6±8.1)cm/s比(23.2±7.1)cm/s]、TAMV[(50.0±10.4)cm/s比(42.4±9.8)cm/s]高于PF组,RI[(0.73±0.05)比(0.76±0.05)]低于PF组,差异均有统计学意义(P<0.05)。结论 e HPF喂养可以引起VLBW早产儿SMA血流变化。Objective To study the effects of extensive hydrolyzed protein formula( e HPF) on the blood flow velocities of superior mesenteric artery( SMA) in very low birth weight preterm( VLBW)infants comparing with preterm infant formula( PF). Methods From Mar. 2011 to Mar. 2015,a total of 64 VLBW infants admitted to NICU of our hospital were randomly assigned into e HPF group( n = 30)and PF group( n = 34). Bolus feeding every 3 hours were started and increased at a speed of20 ml /( kg·d) if well-tolerated. e HPF group received e HPF feeding for 14 days,then changed to PF.PF group received total PF feeding. We used Doppler ultrasound to measure blood flow velocity of the SMA before feeding at 1st,7th and 14 th day of age and 30 min after feeding on the 14 th day of age.Results( 1) The milk intake of e HPF group on the 7th and 14 th day were larger than PF group[( 41. 8 ± 30. 3) ml/kg vs.( 21. 9 ± 19. 2) ml/kg,P〈0. 05]and [( 97. 8 ± 43. 0) ml/kg vs.( 76. 0 ±39. 0) ml / kg,P〈0. 05]. Less time was required to achieve full enteral feeding in e HPF group comparing with PF group [( 18. 5 ± 9. 2) d vs.( 23. 0 ± 8. 5) d,P〈0. 05].( 2) The SMA indicators of PSV [( 53. 6 ± 17. 8) cm / s vs.( 54. 0 ± 15. 7) cm / s ],EDV [( 10. 7 ± 6. 0) cm / s vs.( 12. 5 ±5. 8) cm / s],TAMV [( 23. 5 ± 8. 4) cm / s vs.( 26. 4 ± 10. 5) cm / s],RI [( 0. 79 ± 0. 08) vs.( 0. 76 ±0. 09) ] of both groups on the first day before feeding were similar. PSV,EDV,TAMV of e HPF group were similar between the two groups on the 7th day,[( 75. 1 ± 25. 4) cm / s vs.( 70. 3 ± 19. 0) cm / s,( 16. 2 ± 6. 2) cm vs.( 14. 6 ± 4. 0) cm/s,( 32. 7 ± 11. 2) cm/s vs.( 29. 6 ± 10. 3) cm/s]. PSV[( 95. 7 ± 20. 9) cm/s vs.( 82. 8 ± 20. 5) cm/s],EDV[( 19. 3 ± 6. 6) cm/s vs.( 15. 8 ± 6. 5) cm/s],TAMV[( 42. 3 ± 11. 6) cm / s vs.( 36. 7 ± 10. 4) cm / s] of the e HPF group on the 14 th day were significantly higher th
