RESUMO
The unplanned extubation (UE), a common adverse event in the neonatal intensive care unit (NICU), may result in airway trauma, cardiopulmonary resuscitation, and, in extreme cases, death. As part of the Nationwide Children's Hospital NICU's effort to optimize NICU graduates' neurodevelopmental outcomes, skin-to-skin care of intubated infants is encouraged, while sedation and restraints to prevent UE are strongly discouraged. This project aimed to decrease the UE rate from 1.85 to 1.5 per 100 endotracheal tube (ETT) days. METHODS: The project occurred in a 114-bed, level-IV NICU with approximately 850 admissions per year and 100% outborn infants. A multidisciplinary team began biweekly meetings to review all UE events, later separating these into preventable and nonpreventable. Important ongoing tests of change included assigning a single process owner for UE reporting, ensuring proper ETT securement, and using 2 clinical staff during patient and/or ETT manipulation. RESULTS: Early in the project, enhanced detection led to an increased rate from 1.85 to 3.26 per 100 ETT days. However, identifying preventable events empowered staff to decrease the frequency to 2.03 per 100 ETT days. In August 2017, an ETT taping method change produced an increase in special causes due to decreased compliance. However, when securement methods were enhanced, noncompliance reversed and is now trending favorably. CONCLUSIONS: Decreasing UE in a neurodevelopmentally friendly unit, which avoids sedation and restraints, is challenging. Using a multidisciplinary quality improvement approach and after appropriately capturing events, we reduced UE, with the highest impact of intervention being ETT securement standardization.
RESUMO
BACKGROUND: Nasal CPAP is widely used in neonatal ICUs. Aerosolized medications such as inhaled steroids and ß agonists are commonly administered in-line through nasal CPAP, especially to infants with bronchopulmonary dysplasia. We hypothesized that aerosol delivery to the lungs via variable-flow nasal CPAP in an in vitro model would be unreliable, and that the delivery would depend on the position of the aerosol generator within the nasal CPAP circuit. METHODS: We used a system that employed a test lung placed in a plastic jar and subjected to negative pressure. Simulated inspiration effort was measured with a heated-wire anemometer. We used technetium-99m-labeled diethylene triamine penta-acetic acid as our aerosol. The nebulizer was placed either close to the humidifier or close to the nasal prongs in the circuit, and patient effort was simulated with a minute ventilation of 0.4 L/min. RESULTS: Relative aerosol delivery to the infant test lung with the nebulizer close to the humidifier was extremely low (0.3 ± 0.4%), whereas placing the nebulizer close to the nasal prongs resulted in significantly (P < .001) improved delivery (21 ± 11%). Major areas of aerosol deposition with the nebulizer close to the humidifier versus close to the nasal prongs were: nebulizer (10 ± 4% vs 33 ± 13%, P < .001), exhalation limb (9 ± 17% vs 26 ± 30%, P = .23), and generator tubing (21 ± 11% vs 19 ± 20%, P = .86). Placing the nebulizer close to the humidifier resulted in 59 ± 8% of the aerosol being deposited in the inhalation tubing along the heater wire. CONCLUSIONS: Isotope delivery from an aerosol generator placed near the humidifier on variable-flow nasal CPAP was negligible in this in vitro setup; however, such delivery was significantly improved by locating the aerosol generator closer to the nasal CPAP interface.
