摘要 目的观察不同剂量肺表面活性剂(珂立苏)治疗新生儿呼吸窘迫综合征(NRDS)的临床疗效。方法研究对象为江苏省4家新生儿重症监护病房内诊断为NRDS、〈2500g的早产儿,根据珂立苏首剂量分为高剂量治疗组(69例)和常规剂量治疗组(61例)。高剂量组患儿予珂立苏100mg/kg,常规剂量组予珂立苏70mg/kg。比较2组患儿氧合指数、机械通气、氧疗时间及相关并发症等情况。结果2组患儿用药后动脉血氧分压[P。(02)]迅速改善,高剂量组用药1h、12h、24hP。(02)升至(80.27±36.81)mmHg(1mmHg:0.133kPa)、(73.03±24.94)mmHg、(72.35±24.72)mmHg,改善尤为显著,差异均有统计学意义(P均〈0.05)。同时点高剂量组Pa(O2)均值高于常规剂量组[(67.07±19.94)mmHg、(62.93±21.71)mmHg、(67.95±23.79)mmHg],但差异无统计学意义(P〉0.05)。2组患儿用药后吸入氧体积分数(FiO2)和动脉血二氧化碳分压[Pa(CO2)]下降,持续至48h(P均〈0.05)。珂立苏用药后2组患儿的氧合指数(OI)和动脉/肺泡氧分压(a/APO2)改善,且高剂量组0I用药后1h、12h、24h、36h、48h分别为6.1±2.8、5.6±3.3、5.5±3.5、5.8±4.5、5.3±3.1,较用药前(8.9±4.0)下降显著(P〈0.01)。高剂量组a/APO2用药后1h、12h、24h、36h、48h为0.39±0.22、0.42±0.20、0.45±0.22、0.44±0.22、0.46±0.21,较用药前(0.27±0.18)显著改善(P〈0.01)。高剂量组较常规剂量组机械通气及氧疗时间缩短[(94.54±113.44)h比(109.27±124.87)h,(259.10±280.45)h比(372.31±398.08)h],但差异无统计学意义(P均〉0.05)。2组并发症发生率(肺炎、气胸、颅内出血、动脉导管未闭、肺出血、坏死性小肠结肠炎、脓毒症等)比较差异无统计学意义(P〉0.05)。结论珂矗� Objective To evaluate the relative efficacy of different dosages of Calf Pulmonary Surfaetant ( Calsurf) administration in premature infants with established respiratory distress syndrome (NRDS). Methods Four neonatal intensive care units in Jiangsn province were enrolled. Premature infants,birth weight 〈 2 500 g,with NRDS,received 70 mg/kg (61 eases)or 100 mg/kg (69 cases)Calsurf. Clinical and respiratory parameters were recorded. The primary outcome measures were blood gas analysis of 1 h,12 h and 36 h after administration,the need for oxygenation and venfilatory requirements and the adverse events of NRDS. Results Arterial oxygen tension[ pa ( O2 ) ] results in a significant improvement (80.27 ± 36. 81 ) mmHg, (73.03 ± 24.94) mmHg and (72.35 ± 24.72 ) mmHg at 1 h, 12 h and 24 h in higher dose group( P 〈 0. 05 ) , (67.95 ± 23.79) mmHg, (72.35 ± 24.72 ) mmHg in 24 h, as compared with the lower dose group at the same time [ (67.07 ± 19.94) mmHg, (62.93 ± 21.71 ) mmHg, (67.95 ± 23.79) ramHg ] ( P 〉 0. 05 ). Inspired oxygen ( FiO2 ) and Pa ( O2 ) decreased after administration in two groups and the duration of FiO2 decline lasted to 48 h( all P 〈 0.05 ). The oxygen index (OI) was improved after Calsurf administration, especially in the infants who received lO0 mg/kg of Calsurf with 6.1 ±2.8,5.6 ± 3.3,5.5 ± 3.5,5.8 ± 4.5,5.3 ± 3.1 in 1 h, 12 h,24 h,36 h,48 h, respectively ( P 〈 0.01 ). The arterial - to - alveolar oxygen tension ratio ( a/APO2 ) of 100 mg/kg group was reduced significantly in 1 h, 12 h ,24 h,36 h ,48 h with 0.39 ± 0.22,0.42 ± 0.20,0.45 ± 0.22, 0.44±0.22,0.46 ± 0.21 as compared with0. 27± 0. 18 which was at the time point before administration (P 〈 0.01 ). Although not statistically significant, the mean time of duration of mechanical ventilation and oxygen inhalation of higher dose group were decreased as compared to the lower dose group[ (94.54 ± 113.44) h vs ( 109.27 ± 124
