Flora colonization and oral care in high-risk newborns

Oral Care in Critically Ill Infants and the Potential Effect on Infant Health: An Integrative Review

BACKGROUND

Critically ill infants admitted to the neonatal intensive care unit are at risk for ventilator-associated pneumonia and abnormal oral colonization. Adherence to evidence-based guidelines for oral care in critically ill adults is associated with improved short- and long-term health outcomes. However, oral care guidelines for critically ill infants admitted to the neonatal intensive care unit have not been established, possibly increasing their risk of ventilator-associated pneumonia and other health complications.

OBJECTIVE

To describe and summarize the evidence regarding oral care for critically ill infants admitted to the neonatal intensive care unit and to identify gaps needing further investigation.

METHODS

The MEDLINE (through PubMed) and CINAHL databases were searched for observational studies and randomized controlled trials investigating the effect of oral care on oral colonization, ventilator-associated pneumonia, and health outcomes of infants in the neonatal intensive care unit.

RESULTS

This review of 5 studies yielded evidence that oral care may promote a more commensal oral and endotracheal tube aspirate microbiome. It may also reduce the risk of ventilator-associated pneumonia and length of stay in the neonatal intensive care unit. However, the paucity of research regarding oral care in this population and differences in oral care procedures, elements used, and timing greatly limit any possible conclusions.

CONCLUSIONS

Oral care in critically ill infants may be especially important because of their suppressed immunity and physiological immaturity. Further appropriately powered studies that control for potential covariates, monitor for adverse events, and use recommended definitions of ventilator-associated pneumonia are needed to make clinical recommendations.

Effect of breast milk oral care in infants who underwent surgical correction of ventricular septal defect

OBJECTIVE

This study explored the clinical effect of employing breast milk oral care for infants who underwent surgical correction of ventricular septal defect.

METHODS

A prospective randomised controlled study was conducted in a provincial hospital between January, 2020 and July, 2020 in China. Patients were randomly divided into an intervention group (breast milk oral care, n = 28) and a control group (physiological saline oral care, n = 28). The intervention group was given oral nursing using breast milk for infants in the early post-operative period, and the control group was given oral nursing using physiological saline. Related clinical data were recorded and analysed.

RESULTS

There were no significant differences in age, gender, weight, operation time, cardiopulmonary bypass time, or aortic cross-clamping time between the two groups. Compared with the physiological saline oral care group, the mechanical ventilation duration, the length of ICU stay in the breast milk oral care group were significantly shorter. The time of start feeding and total enteral nutrition were significantly earlier in the intervention group than those in the control group. The incidence of post-operative pneumonia in the breast milk oral care group was 3.6%, which was significantly lower than that of the physiological saline oral care group.

CONCLUSION

The use of breast milk for oral care in infants who underwent surgical correction of VSD can reduce the incidence of post-operative pneumonia and promote the recovery of gastrointestinal function.

Comparison of the Effect of Breast Milk and Sodium Bicarbonate Solution for Oral Care in Infants with Tracheal Intubation After Cardiothoracic Surgery

Background: This study aimed to explore the effect of breast milk and sodium bicarbonate solution used in oral care of infants with tracheal intubation after cardiothoracic surgery. Methods: A randomized clinical controlled trial was conducted in a provincial hospital in China. Fifty infantile patients were randomly divided into two groups: the patients in the study group (n = 25) used breast milk for oral care and the patients in the control group (n = 25) used sodium bicarbonate solution for oral care. The relevant clinical data were recorded, including the mechanical ventilation duration, length of intensive care unit (ICU) stay, length of hospital stay, and complications. Results: The length of ICU stay, length of hospital stay, and duration of mechanical ventilation were shorter in the study group, but the difference was not statistically significant (p > 0.05). However, the incidence of thrush and ventilator-associated pulmonary infection in the study group was significantly lower than that in the control group (p < 0.05). Conclusion: The use of breast milk for oral care has a positive effect on the prevention of thrush and ventilator-associated pulmonary infection in infants with tracheal intubation after cardiothoracic surgery.
