Exclusion criteria
Exclusion criteria: 1.Apnea due to: hypoxic-ischemic encephalopathy, meningitis, seizures, pneumonia which does not improve even if it treats obstructive apnea. 2.Blood urea nitrogen >20 mg/dL, serum creatinine >1.5 mg/dL 3.Serum AST or ALT >3 times the upper limit of normal. 4.Patients require mechanically-assisted ventilation (containing nasal CPAP) 5.Previous treatment with methylxanthines within 7 days prior to study enrollment. 6.Previous treatment with H2 antagonists (i.e., cimetidine or ranitidine) within 7 days prior to study enrollment. 7.Participant of other clinical trial within 6 months.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Success rates for controlling of apnea episode in each observation day (at least 50% reduction of apnea episodes from baselineTimepoint: 1, 2, 3, 4, 5, 6,7, 8, 9 and 10 day | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The change of frequency of apnea episode from baseline in each observation day 2. Time to event: Days until next events occurred intil l next events occurred. (The definition of events are, Not at least 50% reduction of apnea episode Not improving the frequency of episode from baseline Needs mechanical/bag valve mask ventilation.) 3. The change of average duration time of apnea episode from baseline in each observation day 4.The change of lowest oxygen saturation during apnea episodes from baseline in each observation day 5. The proportion of less than 85% oxygen saturation during apnea episodes in each observation dayTimepoint: 1, 2, 3, 4, 5, 6,7, 8, 9 and 10 day | — |
