Comparison of nasal prongs and nasopharyngeal catheter for the delivery of oxygen in children with hypoxemia because of a lower respiratory tract infection☆,☆☆,★,★★

Patients
The study was performed in the pediatric ward of the Royal Victoria Hospital in Banjul, the only pediatric referral hospital in The Gambia. In the first year of the study, children with a provisional diagnosis of pneumonia or bronchiolitis were assessed by a trained field assistant. The SaO2, respiratory rate, and temperature were measured. During the second year of the study, all children admitted to the hospital were screened in this way. Children with pneumonia or bronchiolitis who were not
Patients
One hundred twenty—three patients with an SaO2 less than 90% were initially assessed. Five children were excluded-three with cyanotic congenital heart disease and two with central hypopnea and gasping. Thus 118 children were enrolled into the study. Sixty-four of the children (54%) were male. The median age of the study patients was 5 months, with a range from 10 days to 58 months. Ninety-six children had a diagnosis of pneumonia. Of these, 13 had measles as a previous or concurrent illness, 8
DISCUSSION
Both the NP catheter and the nasal prongs produce adequate oxygenation with relatively low oxygen flow rates in the majority of children with hypoxemia. We did not find any patient who could be oxygenated with one of the systems and not with the other. However, some patients needed several hours of therapy to reach an SaO2 of 95%. This might indicate intrapulmonary shunting, which decreased as a result of antibiotic or oxygen therapy. In most hospitals in developing countries, oxygen will be

New Methods for Noninvasive Oxygen Administration
2019, Clinics in PerinatologyCitation Excerpt :This study showed that a flow of oxygen (Fio2 = 1.0) at 0.15 L/kg/min through an 8F cannula provided transcutaneous oxygen tensions similar to those of head box oxygen at Fio2 of 0.5.24 In a randomized crossover study comparing oxygen modes of delivery in 60 children with respiratory tract infections, those on nasal cannula required an average of 26% higher flow rates (P = .003) compared with nasopharyngeal oxygen to achieve similar oxygen saturations.22 This was likely due to the generation of inadvertent positive end-expiratory pressure with the use of these interfaces at higher flow rates.
Randomized trial of a novel double lumen nasopharyngeal catheter versus traditional nasal cannula during total intravenous anesthesia for gastrointestinal procedures
2017, Journal of Clinical AnesthesiaCitation Excerpt :Because the nasopharyngeal catheter provides oxygen supplementation immediately supraglottic, it delivers oxygen past the point of airway obstruction that is induced by general anesthesia [9]. It has been typically used in the pediatric patients, intensive care unit or the postoperative period; and it has been shown to require lower oxygen flow rates to achieve the same oxygenation as face mask or nasal cannula [7,8,10–13]. However, its use for patients undergoing general anesthesia for endoscopic procedures has not been described.
Risk factors of hypoxia during flexible bronchoscopy use in infants
2012, Journal of the Chinese Medical AssociationComparison of oxygenation among different supplemental oxygen methods during flexible bronchoscopy in infants
2011, Journal of the Chinese Medical AssociationCitation Excerpt :In infants with difficult nasal approach, a well-secured oropharyngeal catheter can be substituted. There may be some adverse effects when using NPC oxygen, including drying mucosa, kinking, lumen blocking with mucus16 and esophageal migration. Therefore, even in its short-term use, we advise that its oxygen flow should be appropriately warmed and humidified.
