ABSTRACT
Objective:
To analyze the status of neonatal respiratory distress syndrome (RDS) management in 10 hospitals in Northwest China over the past five years and to investigate the strategies for improving the prevention and treatment of RDS.Methods:
This retrospective study involved premature infants with RDS who were admitted to the neonatal intensive care units (NICU) of 10 hospitals (six in Shaanxi Province, three in Gansu Province, and one in Xinjiang Uygur Autonomous Region) of the Northwest China Neonatal Collaborative Group within 3 d after birth from January 1 to December 31, 2016, and from January 1 to December 31, 2021. Basic information, perinatal condition, treatment approaches, complications, and prognosis of the patients were compared. T-test, rank sum, and Chi-square tests were used for statistical analysis.Result:
(1) This study enrolled 322 premature infants with RDS in 2016 and 349 in 2021. Premature infants at the gestational age of 30 to 33 weeks were mainly affected, and the majority were male [64.3% (207/322) and 57.3% (200/349)]. The average maternal age in 2021 was older than that in 2016 [(30.6±4.8) years vs (28.6±5.4) years, t=24.02, P<0.001], and the proportion of women at advanced maternal age was also higher in 2021 [19.2% (67/349) vs 12.4% (40/322), χ2=4.18, P<0.05]. (2) The proportions of pregnancies conceived with assisted reproductive technologies [11.7% (41/349) vs 1.9% (6/322), χ2=25.12], underwent routine prenatal examinations [58.5% (204/349) vs 30.4% (98/322), χ2=53.33], exposed to steroids [62.2% (217/349) vs 28.6% (92/322), χ2=82.58] and delivered by cesarean section or elective cesarean section [73.6% (257/349) vs 51.6% (166/322), χ2=35.06; 24.1% (84/349) vs 6.5% (21/322), χ2=39.07], as well as the ratio of cesarean scar pregnancy [7.4% (26/349) vs 3.4% (11/322), χ2=5.23] were all higher in 2021 than those in 2016 (all P<0.05). Moreover, the incidence of fetal distress [30.1% (105/349) vs 20.2% (65/322), χ2=8.68], gestational hypertension [24.6% (86/349) vs 13.0% (42/322), χ2=14.59], premature rupture of membranes [16.0% (56/349) vs 10.2% (33/322), χ2=4.89], meconium-stained amniotic fluid [12.6% (44/349) vs 5.6% (18/322), χ2=9.83], placental abruption [10.3% (36/349) vs 5.3% (17/322), χ2=5.84], gestational diabetes mellitus [10.3% (36/349) vs 1.6%(5/322), χ2=22.41], chorioamnionitis [4.6%(16/349) vs 0.9% (3/322), χ2=8.12], thyroid dysfunction [4.3% (15/349) vs 0.6% (2/322), χ2=7.88] and heart disease [4.3% (15/349) vs 0.3% (1/322), χ2=9.17] were higher in 2021 than in 2016 (all P<0.05). (3) In 2021, the rate of pulmonary surfactant (PS) usage, the dosage of porcine PS, and the proportion of bovine PS usage were all significantly higher than those in 2016 [73.6% (257/349) vs 67.1% (216/322), χ2=11.62; (178.5±38.0) mg/kg vs (165.2±42.8) mg/kg, t=7.85; 47.9% (123/257) vs 19.4% (42/216), χ2=41.72; all P<0.01]. No significant difference in the incidence of intubation-surfactant-extubation (INSURE), early PS administration (≤2 h after birth), or the arterial blood gas values before and after PS treatment was found between the cases enrolled in 2021 and 2016. The duration of antibiotic treatment [7.0 d (5.0-14.0 d) vs 5.0 d (1.0-8.0 d), Z=7.55] and assisted ventilation [144 h (81-264 h) vs 73 h (47-134 h), Z=8.20] and the median hospital stay [24 d(14-42 d) vs 16 d (10-25 d), Z=6.74] were significantly longer in 2021 than in 2016 (all P<0.01). More patients required nasal intermittent positive pressure ventilation [29.6% (100/338) vs 1.0% (3/306), χ2=97.81] and conventional ventilation [42.6% (144/338) vs 30.1% (92/306), χ2=10.87] in 2021 as compared with those five years ago (both P<0.01). (4) In 2021, the incidence of patent ductus arteriosus [15.5% (54/349) vs 6.2% (20/322), χ2=63.40], bronchopulmonary dysplasia [9.2% (32/349) vs 2.8% (9/322), χ2=12.88], persistent pulmonary hypertension [5.4% (19/349) vs 0.6% (2/322), χ2=12.85], periventricular leukomalacia [4.3% (15/349) vs 1.2% (4/322), χ2=7.52] and pneumothorax [3.4% (12/349) vs 0.3% (1/322), χ2=9.68] increased as compared with those in 2016 (all P<0.05), while the incidence of nosocomial infection decreased significantly [7.4% (26/349) vs 19.6% (63/322), χ2=21.37, P<0.001]. (5) The cure rate of premature infants with RDS was 70.8% (247/349) in 2021, which was significantly higher than that in 2016 [56.2% (181/322), χ2=15.37, P<0.001]. Moreover, the rate of withdrawing treatment and the total mortality rate was lower in 2021 than in 2016 [7.7% (27/349) vs 14.3% (46/322), χ2=7.41; in-hospital 1.4% (5/349) vs 5.6% (18/322), χ2=8.74; out of hospital 8.3% (29/349) vs 13.7% (44/322), χ2=4.96; all P<0.05].Conclusions:
The clinical management of RDS in premature infants in the involved hospitals has been improved. However, there is room for improvement in prenatal examinations.
