摘    要:目的探讨高频震荡通气(HFOV)联合西地那非对新生儿持续肺动脉高压(PPHN)的治疗效果。方法诊断PPHN新生儿34例,17例接受高频震荡通气(HFOV)治疗,17例接受高频震荡通气(HFOV)联合西地那非治疗,比较两组肺动脉平均血流速度、心输出量、心率、血压、经皮血氧,治疗前后吸入氧浓度(FiO2)、动脉血氧分压(PaO,)、动脉血二氧化碳分压(PaCO:)及氧合指数(OI)的变化。结果治疗前及治疗6、12、24和48h,HFOV联合西地那非治疗组肺动脉血流速度分别为(17.1±8.3)、(26.5±9.7)、(28.6±5.4)、(31.5±5.1)和(31.7±3.8)cm/s,01分另n为(36.4±17.5)、(23.9±7.5)、(17.9±8.2)、(13.3±2.8)和(10.2±4.1),Pa02/Fi02值分别为(56.8±5.7)、(175.3士7.6)、(210.5±9.7)、(250.3±8.2)和(310.7±10.8);HFOV组肺动脉血流速度分别为(17.5±8.1)、(21.1±7.3)、(22.5±6.9)、(23.3±5.8)和(24.1±3.3)cm/s,01分别为(34.3±16.5)、(31.5±11.6)、(28.6±7.5)、(19.5±6.1)和(16.8±7.8),Pa02/E02值分别为(60.2±6.8)、(113.2±19.7)、(153.6±12.6)、(191.3±9.4)和(265.3±8.5);两组上述3项指标治疗各时间点与治疗前比较,差异均有统计学意义;而两组心输出量、心率和血压与治疗前比较,差异均无统计学意义。HFOV联合西地那非治疗组的肺动脉血流速度、Pa02、Pa02/EO:值在各个时间点均高于HFOV组,而0I低于单纯HFOV治疗组,差异有统计学意义。结论HFOV联合西地那非治疗新生儿PPHN疗效显著,不良反应少,值得临床推广。

Abstract:Objective To evaluate the efficacy of high frequency oscillatory ventilation (HFOV) combined with sil- denafil in the treatment of persistent pulmonary hypertension in newborns (PPHN). Methods Thirty-fcur newborns diag- nosed with PPHN were divided into two groups: 17 treated with HFOV (HFOV group) and the other 17 with HFOV plus sil- denalll (HFOV sildenafil group). Mean blood speed of pulmonary arteries, cardiac output, heart rate, bloed pressure, trans- cutaneous oxygen saturation, fraction of inspired oxygen ( FiO2 ), arterial partial pressure of oxygen ( PaO2 ), partial pressure of carbon dioxide in artery ( PaCO2 ), and oxygen index (OI) before and after treatment were compared between the two groups. Results Pulmonary blood flow velocity was(17.1 ±8.3),(26.5±9.7),(28.6 ±5.4),(21.5 ±5.1), and (31.7 ±3. 8)cm/s before and at 6h, 12, 24, and 48 after treatment, respectively, in HFOV sildenafil gr3up and the corre- sponding parameter for eardiae output was (220 ±35), (249 ± 17), (280 ± 19), (282 ± 11 ), and 290 ± 15 ml/kg ~ min, re- spectively. In HFOV group, pulmonary artery blood flow was ( 17. 5 ± 8. 1 ), ( 21.1 ± 7. 3 ), ( 22. 5 ± 6. 9), ( 23. 3 ± 5. 8 ), and (24. 1 ±3. 3)em/s, respectively, before and at 6, 12, 24, and 48 h after treatment, and the corresponding figures for cardiac output was(224 ±39) ,(244 ±41 ), (271 ± 12), (276 ± 10) and (272 ± 13) ml/kg ~ min, respectively. In HFOV sildenafil group, Ol was (36.4 ±17.5) ,(23.9 ±7. 5), (17.9 ±8.2) ,(13. 3 ±2. 8) ,(10.2 ±4. 1) before and after 6, 12, 24, and48 h, respectively, and PaO2/FiO2 was(56. 8 ±5.7), (175.3 ±7.6), (210.5 ±9.7), (250.3 ±8.2), and(310.7 -± 10.8), respectively. In HFOV group, Olwas (34.3±16.5),(31.5±11.6),(28.6±7.5),(19.5±6 1), and(16.8 -± 7. 8) before and after 6, 12, 24, and 48h, respectively, and PaO2/FiO2 was (60. 2 ± 6. 8), ( 113.2 ± 19. 7), ( 153.6 ± 12.6), (191.3 ± 9.4), and ( 265.3 -± 8. 5 ) , respectively. Compared with before treatment, improvement was seen in all the four parameters at either time point after treatment in both groups. HFOV sildenafil group had better results of PaO2/ FiO2 and OI at any time point than HFOV group. Conclusion HFOV combined with sildenafil is effective and has fewerside-effects in the treatment of PPHN. Fm'ther studies with larger sample size are warranted.
