Abstract
Background:
Preventing significant oxygen desaturation and hypotension through adequate analgesia and sedation during nonemergent Intubation In neonates is desirable. However, in many neonatal intensive care units, elective intubations occur without adequate premedication. There is significant variation In the choice of premedication agen(s) and doses, and an ideal regimen for use during nonemergent intubation has not been developed.
Objective:
To evaluate the efficacy of an algorithm developed for analgesia and sedation during nonemergent Intubation in neonates.
Methods:
Prospectively collected continuous quality Improvement data on a premedication algorithm for nonemergent intubation were analyzed following institutions] review board approval. Midazolam 0.1 mg/kg and fentanyl 2 μg/kg (if the patient was not already receiving morphine for sedation) were administered prior to nonemergent intubation. Heart rate, oxygen saturation, respiration rate, mean arterial pressure, and pain scores were recorded at baseline prior to medication administration, during the procedure, and for 2 hours after the procedure. Data during laryngoscopy and until the time of lube taping were obtained from Ine bedside cardiorespiratory monitor. Additional fentanyl was allowed for more than 3 intubation attempts and rocuronium 0.6 mg/kg was allowed for more than 5 attempts. The physiological changes that occurred over time were compared with baseline. The number of attempts made, time to intubation, and medications used are presented.
Results:
Ninety evaluable patients were included. Mean ± SD birth weight and postnatal age at treatment were 2040 ± 961 g and 14 ± 17 days, respectively. Heart rate decreased and oxygen saturation Increased significantly (160 vs 154 beats/min, p = 0.01; 96.4% vs 93.8%. p = 0.002, respectively) from baseline to completion of the procedure; however, mean arterial pressure showed no significant difference (44.9 vs 44.7 mm Hg; p = 0.85; n = 68). The number of attempts at Intubation were recorded (or 66 patients; of those, 52 required 3 or fewer attempts for successful Intubation (median, 2).The lime to successful intubation was 7.2 ± 5.6 minutes (recorded in 45 pts.). Average fentanyl and midazolam doses were 1.92 ± 0.53 μg/kg and 0.096 ± 0.026 mg/kg, respectively. No patient received rocuronium.
Conclusions:
A systematic approach to premedication during nonemergent intubation successfully prevented acute physiological changes.
