Assessing the Impact of Nasotracheal Intubation on Postoperative Neonates With Congenital Heart Disease: A Quality Improvement Project at a Single Heart Center.

OBJECTIVES: Nasotracheal intubation (NTI) is associated with fewer unplanned extubations and improved oral motor skills compared with orotracheal intubation (OTI). Our study aimed to implement a practice change from OTI to NTI for neonatal cardiac surgery and assess impact on postoperative outcomes. DESIGN: Single-center, prospective, quality improvement study. SETTING: Academic children's hospital. PATIENTS: One hundred thirty neonates undergoing cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: NTI during index cardiac surgery. MEASUREMENTS AND MAIN RESULTS: Data were collected between January 2019 and April 2021. The study was implemented in three phases: retrospective: OTI neonates ( n = 43), I: safety and feasibility of NTI ( n = 17), and II: speech language pathology (SLP) evaluation on postoperative day 1 facilitated by NTI ( n = 70). Retrospective and phase I patients were combined for analysis. Groups were compared using Kruskal-Wallis test or Wilcoxon rank-sum test.Ninety-one percent of eligible neonates were nasotracheally intubated. There were no clinically significant complications. Days to first SLP encounter decreased from a median 4.5 days (interquartile range [IQR], 3.8-6.2) to 1.1 days (IQR, 1.0-1.9; p < 0.001). Oral readiness time decreased from a median of 6.6 days (IQR, 5.4-8.9) to 4.3 days (IQR, 3.4-8.6; p < 0.001). . CONCLUSIONS: NTI is feasible and safe in neonatal cardiac surgery. System-level engagement with stakeholders is necessary to change clinical practice. NTI facilitates early SLP evaluation and treatment and significantly affects oral readiness after neonatal cardiac surgery.

Changes in Anesthetic and Postoperative Sedation-Analgesia Practice Associated With Early Extubation Following Infant Cardiac Surgery: Experience From the Pediatric Heart Network Collaborative Learning Study.

OBJECTIVES: The Pediatric Heart Network sponsored the multicenter Collaborative Learning Study that implemented a clinical practice guideline to facilitate early extubation in infants after repair of isolated coarctation of the aorta and tetralogy of Fallot. We sought to compare the anesthetic practice in the operating room and sedation-analgesia management in the ICU before and after the implementation of the guideline that resulted in early extubation. DESIGN: Secondary analysis of data from a multicenter study from January 2013 to April 2015. Predefined variables of anesthetic, sedative, and analgesia exposure were compared before and after guideline implementation. Propensity score weighted logistic regression analysis was used to determine the independent effect of intraoperative dexmedetomidine administration on early extubation. SETTING: Five children's hospitals. PATIENTS: A total of 240 study subjects who underwent repair of coarctation of the aorta or tetralogy of Fallot (119 preguideline implementation and 121 postguideline implementation). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Clinical practice guideline implementation was accompanied by a decrease in the median total intraoperative dose of opioids (49.7 vs 24.0 µg/kg of fentanyl equivalents, p < 0.001) and benzodiazepines (1.0 vs 0.4 mg/kg of midazolam equivalents, p < 0.001), but no change in median volatile anesthetic agent exposure (1.3 vs 1.5 minimum alveolar concentration hr, p = 0.25). Intraoperative dexmedetomidine administration was associated with early extubation (odds ratio 2.5, 95% CI, 1.02-5.99, p = 0.04) when adjusted for other covariates. In the ICU, more patients received dexmedetomidine (43% vs 75%), but concomitant benzodiazepine exposure decreased in both the frequency (66% vs 57%, p < 0.001) and cumulative median dose (0.5 vs 0.3 mg/kg of ME, p = 0.003) postguideline implementation. CONCLUSIONS: The implementation of an early extubation clinical practice guideline resulted in a reduction in the dose of opioids and benzodiazepines without a change in volatile anesthetic agent used in the operating room. Intraoperative dexmedetomidine administration was independently associated with early extubation. The total benzodiazepine exposure decreased in the early postoperative period.

Respiratory Testing and Hospital Outcomes in Asymptomatic Infants Undergoing Heart Surgery.

Respiratory viral infections in infants undergoing congenital heart surgery lead to prolonged intubation time, hospital (HLOS) and cardiac intensive care unit length of stay (CICU LOS). The objective of this study was to evaluate the prevalence of respiratory viruses using molecular testing in otherwise healthy infants presenting for low complexity heart surgery, and to evaluate the impact of a positive viral screen and study questionnaire on post-surgical HLOS, CICU LOS, intubation time, respiratory complications, and oxygen therapy at home discharge. Sixty-nine infants (1 month to 1 year) undergoing cardiac surgery from November to May of the years 2012 to 2014 were prospectively enrolled, surveyed and tested. We compared the outcomes of positive molecular testing and positive study questionnaire to test negative subjects. We also evaluated the predictive value of study questionnaire in identification of viruses by molecular testing. Of the 69 enrolled infants, 58 had complete information available for analysis. 17 (30%) infants tested positive by molecular testing for respiratory pathogens. 38 (65%) had a "positive" questionnaire. Among the 20 viruses detected, Human Rhinovirus was the most common 12 (60%). Seven (12%) of the 58 patients developed respiratory symptoms following surgery prompting molecular testing. Four of these tested positive for a respiratory virus post-surgically. Neither positive molecular testing nor a positive questionnaire prior to surgery was associated with greater post-operative HLOS, CICU LOS, intubation time, respiratory complications, or use of oxygen at discharge compared to negative testing. The questionnaire poorly predicted positive molecular testing. Routine screening for respiratory viruses in asymptomatic infants may not be an effective strategy to predict infants at risk of post-operative complications.

Propofol for procedural sedation in children in the emergency department.

STUDY OBJECTIVE: We determine the safety and efficacy of propofol sedation for painful procedures in the emergency department (ED). METHODS: A consecutive case series of propofol sedations for painful procedures in the ED of a tertiary care pediatric hospital from July 2000 to July 2002 was performed. A sedation protocol was followed. Propofol was administered in a bolus of 1 mg/kg, followed by additional doses of 0.5 mg/kg. Narcotics were administered 1 minute before propofol administration. Adverse events were documented, as were the sedation duration, recovery time from sedation, and total time in the ED. RESULTS: Three hundred ninety-three discrete sedation events with propofol were analyzed. Procedures consisted of the following: fracture reductions (94%), reduction of joint dislocations (4%), spica cast placement (2%), and ocular examination after an ocular burn (0.3%). The median propofol dose was 2.7 mg/kg. Ninety-two percent of patients had a transient (

Propofol sedation by emergency physicians for elective pediatric outpatient procedures.

STUDY OBJECTIVE: We describe the efficacy of propofol sedation administered by pediatric emergency physicians to facilitate painful outpatient procedures. METHODS: By using a protocol for patients receiving propofol sedation in an emergency department-affiliated short-stay unit, a prospective, consecutive case series was performed from January to September 2000. Patients were prescheduled, underwent a medical evaluation, and met fasting requirements. A sedation team was present throughout the procedure. All patients received supplemental oxygen. Sedation depth and vital signs were monitored while propofol was manually titrated to the desired level of sedation. RESULTS: There were 291 separate sedation events in 87 patients. No patient had more than 1 sedation event per day. Median patient age was 6 years; 57% were male patients and 72% were oncology patients. Many children required more than 1 procedure per encounter. Most commonly performed procedures included lumbar puncture (43%), intrathecal chemotherapy administration (31%), bone marrow aspiration (19%), and bone biopsy (3%). Median total propofol dose was 3.5 mg/kg. Median systolic and diastolic blood pressures were lowered 22 mm Hg (range 0 to 65 mm Hg) and 21 mm Hg (range 0 to 62 mm Hg), respectively. Partial airway obstruction requiring brief jaw-thrust maneuver was noted for 4% of patient sedations, whereas transient apnea requiring bag-valve-mask ventilation occurred in 1% of patient sedations. All procedures were successfully completed. Median procedure duration was 13 minutes, median sedation duration was 22 minutes, and median total time in the short stay unit was 40 minutes. CONCLUSION: Propofol sedation administered by emergency physicians safely facilitated short painful procedures in children under conditions studied, with rapid recovery.
