ABSTRACT
Objective To investigate the effects of caffeine citrate and aminophylline in treatment of primary apnea of premature infants and its related complications. Methods A total of 152 preterm infants who were diagnosed primary apnea within 10 days after birth were randomly divided into caffeine citrate group(n=77) and aminophylline group(n =75). The changes in the time of the apnea disappeared after treating,needing oxygen,non-invasive and invasive mechanical ventilation,and the incidence of bronchopul-monary dysplasia ( BPD ) , necrotizing enterocolitis, retinopathy of prematurity, patent ductus arteriosus (PDA),intercranial hemorrhage(ICH)were compared between the two groups. Results The time of the apnea disappeared after treating[(47. 4 ± 5. 3) h],needing oxygen[(20. 5 ± 7. 6) d],non-invasive mechani-cal ventilation[(8. 7 ± 4. 2) d] and invasive mechanical ventilation[(1. 0 ± 1. 3) d] in the caffeine citrate group were significantly lower than those in the aminophylline group [ ( 54. 8 ± 6. 2 ) h, ( 24. 4 ± 8. 5 ) d, (10.4±5.3)d,(10.4±5.3)d,respectively](P0. 05). Conclusion The caffeine citrate has a better efficacy in the treating primary apnea of preterm infants than aminophylline. It can also decrease the incidence of BPD,PDA and ICH in premature infants.
ABSTRACT
Objective To investigate the clinical effects and safety of Aminophylline and Caffeine citrate in the treatment of preterm infants with primary apnea. Methods 130 preterm infants with primary apnea were chosen and randomly divided into both group including the Aminophylline group (65 children) with aminophylline and the Caffeine citrate group (65 children) with Caffeine citrate on the basis of conventional intervention; and the total oxygen inhalation time, mechanical ventilation time, hospitalization time, the complications incidence with follow-up and the levels of development quotient for short-term of both groups were compared. Results The total oxygen inhalation time, the mechanical ventilation time and the hospitalization time of Caffeine citrate group were significantly shorter than aminophylline group(P<0.05). The incidence of PDA, BPD and ROP of Caffeine citrate group were significantly lower than aminophylline group(P<0.05). There was no significant difference in the incidence of intracranial hemorrhage, PVL and NEC between two groups. The development quotient levels in 24 weeks and 48 weeks after treatment of Caffeine citrate group were significantly higher than aminophylline group(P<0.05). Conclusion Compared with Aminophylline, Caffeine citrate on the basis of conventional intervention in the treatment of preterm infants with primary apnea could efficiently shorten the oxygen inhalation time, the mechanical ventilation time and clinical disease course, reduce the related complications risk and be helpful to promote the intellectual development.
ABSTRACT
Objective Discuss the clinical efficacy of caffeine citrate and aminophylline in treatment of primary apnea of prematurity.Methods 80 cases of primary apnea of prematurity were selected.They were divided into two groups randomly.The control group (40 cases) received aminophylline treatment and the observation group (40 cases) received caffeine citrate therapy.The efficacy of caffeine citrate and aminophylline in treatment of primary apnea ofprematudty was evaluated by efficacy,primary apnea episodes and disappeared time,adverse reaction during treatment.Results The effective rate of observation group was 85％,the effective rate of control group was 75％.The observation group had higher efficiency (P ＜ 0.05).The frequency of apnea of observation group was less than that of the control group.The disappearance time of observation group was shorter than that of the control group (P ＜ 0.05).During the treatment,the tachycardia,feeding intolerance,bronchopulmonary dysplasia and other adverse reactions rate of observation group was lower than that of the control group (P ＜ 0.05).Conclusion Compared with aminophylline,caffeine citrate had a good therapeutic effect of primary apnea of prematurity.It can reduce apnea frequency,eliminate clinical symptoms with high safety.It was an ideal drug for treatment of primary apnea.
ABSTRACT
Objective To explore the therapeutic effect and security of caffeine citrate in preventing primary apnea of preterm infants by observing the clinical effect, adverse reaction and prognosis of caffeine citrate preventing the primary apnea. Methods A total of 132 preterm infants admitted to neonatal department of Tianjin Central Hospital of Obstetrics and Gynecology were selected during January 2015 to July 2016. They were randomly divided into two groups, one was the caffeine group, and the other was the control group. The infants of caffenine group were intravenous injected caffeine citrate 24 hours after birth, with the first dose 20 mg/kg, and the maintain dose 5 mg/kg every 24 hours, until the corrected gestational age was 34 weeks. The infants of control group were not given methylxanthine drugs. Data were compared between two groups including the incidence of apena after 48 hours of giving drugs, the period of using nasal continuous positive airway pressure (n-CPAP) or ventilator, the incidence of feeding intolerance, tachycardia, patent ductus arteriosus (PDA), intracranial hemorrhage (HIE), necrotizing enterocolitis (NEC),and bronchopulmonary dysplasia (BPD), weight growth rate and the length of hospitalization. Results There were significantly lower incidence of apnea after 48 hours, the period of using nasal continuous positive airway pressure or ventilator, incidence of patent ductus arteriosus and intracranial hemorrhage and the duration of hospitalization in caffeine group than those in control group (P 0.05). Conclusion The preterm infants given caffeine could reduce the incidence of the primary apnea, improve the prognosis of the preterm infants, and no significant adverse reaction.
ABSTRACT
Objective To investigate the clinical effect of caffeine citrate combined with continuous positive airway pressure( CPAP) in the treatment of primary apnea of prematurity.Methods 80 premature infants with primary apnea who received therapy from January 2014 to August 2015 were selected as research subjects.According to ran-dom number table,the infants were divided into two groups equally.Besides conventional treatments,the control group received treatment of caffeine citrate,while the observation group received CPAP and caffeine citrate.Then,the cura-tive efficacy,situation of apnea and adverse reactions were compared.Results The total effective rate between the observation group and the control group had statically significant difference(95.0%vs.77.5%,P0 .0 5 ) . Conclusion Caffeine citrate in combination with CPAP is effective for primary apnea of prematurity,which can sig-nificantly increase curative efficacy,lessen seizure frequency of apnea,shorten duration of seizure and disappearance time of symptoms with less adverse reactions.
ABSTRACT
Objective To asses the clinical efficiency of Naloxone injection in the treatment of Primary Apnea of preterm infant. Methods There were 116 cases randomly divided into experimental group including 72 cases, whch was treated with Naloxone injection and control group including 44 cases,which was treated with Aminophylline injection. Results The total effective rates of the two groups are 95.8% and 68.2%.The rates of excellence of the two groups are 63.9% and 40.9%,respectively,there is a significant difference between them(P＜0.01). Conclusion Naloxone injection is effective to treat Primary Apnea of preterm infant.
