Operation airway: the first sustainable, multidisciplinary, pediatric airway surgical mission.

OBJECTIVE: This study aimed to describe the development and implementation of the first sustainable, multidisciplinary, pediatric airway surgical mission in an underserved country. METHODS: This prospective, qualitative study was conducted for the first 4 Operation Airway missions in Quito, Ecuador. The major goals of the missions were to assist children with aerodigestive abnormalities, create a sustainable program where the local team could independently provide for their own patient population, develop an educational curriculum and training program for the local team, and cultivate a collaborative approach to provide successful multidisciplinary care. RESULTS: Twenty patients ages 4 months to 21 years were included. Twenty-three bronchoscopies, 5 salivary procedures, 2 tracheostomies, 1 T-tube placement, 1 tracheocutaneous fistula closure, 2 open granuloma excisions, and 6 laryngotracheal reconstructions (LTRs) were performed. All LTR patients were decannulated. A new type of LTR (1.5 stage) was developed to meet special mission circumstances. Two videofluoroscopic swallow studies and 40 bedside swallow evaluations were performed. One local pediatric otolaryngologist, 1 pediatric surgeon, 3 anesthesiologists, 7 intensivists, 16 nurses, and 2 speech-language pathologists have received training. More than 25 hours of lectures were given, and a website was created collaboratively for educational and informational dissemination (http://www.masseyeandear.org/specialties/pediatrics/pediatric-ent/airway/OperationAirway/). CONCLUSION: We demonstrated the successful creation of the first mission stemming from a teaching institution with the goal of developing a sustainable, autonomous surgical airway program.

Perioperative dexamethasone administration and risk of bleeding following tonsillectomy in children: a randomized controlled trial.

CONTEXT: Corticosteroids are commonly given to children undergoing tonsillectomy to reduce postoperative nausea and vomiting; however, they might increase the risk of perioperative and postoperative hemorrhage. OBJECTIVE: To determine the effect of dexamethasone on bleeding following tonsillectomy in children. DESIGN, SETTING, AND PATIENTS: A multicenter, prospective, randomized, double-blind, placebo-controlled study at 2 tertiary medical centers of 314 children aged 3 to 18 years undergoing tonsillectomy without a history of bleeding disorder or recent corticosteroid medication use and conducted between July 15, 2010, and December 20, 2011, with 14-day follow-up. We tested the hypothesis that dexamethasone would not result in 5% more bleeding events than placebo using a noninferiority statistical design. INTERVENTION: A single perioperative dose of dexamethasone (0.5 mg/kg; maximum dose, 20 mg), with an equivalent volume of 0.9% saline administered to the placebo group. MAIN OUTCOME MEASURES: Rate and severity of posttonsillectomy hemorrhage in the 14-day postoperative period using a bleeding severity scale (level I, self-reported or parent-reported postoperative bleeding; level II, required inpatient admission for postoperative bleeding; or level III, required reoperation to control postoperative bleeding). RESULTS: One hundred fifty-seven children (median [interquartile range] age, 6 [4-8] years) were randomized into each study group, with 17 patients (10.8%) in the dexamethasone group and 13 patients (8.2%) in the placebo group reporting bleeding events. In an intention-to-treat analysis, the rates of level I bleeding were 7.0% (n = 11) in the dexamethasone group and 4.5% (n = 7) in the placebo group (difference, 2.6%; upper limit 97.5% CI, 7.7%; P for noninferiority = .17); rates of level II bleeding were 1.9% (n = 3) and 3.2% (n = 5), respectively (difference, -1.3%; upper limit 97.5% CI, 2.2%; P for noninferiority < .001); and rates of level III bleeding were 1.9% (n = 3) and 0.6% (n = 1), respectively (difference, 1.3%; upper limit 97.5% CI, 3.8%; P for noninferiority = .002). CONCLUSIONS: Perioperative dexamethasone administered during pediatric tonsillectomy was not associated with excessive, clinically significant level II or III bleeding events based on not having crossed the noninferior threshold of 5%. Increased subjective (level I) bleeding events caused by dexamethasone could not be excluded because the noninferiority threshold was crossed.

Quality improvement utilizing in-situ simulation for a dual-hospital pediatric code response team.

OBJECTIVE: Given the rarity of in-hospital pediatric emergency events, identification of gaps and inefficiencies in the code response can be difficult. In-situ, simulation-based medical education programs can identify unrecognized systems-based challenges. We hypothesized that developing an in-situ, simulation-based pediatric emergency response program would identify latent inefficiencies in a complex, dual-hospital pediatric code response system and allow rapid intervention testing to improve performance before implementation at an institutional level. METHODS: Pediatric leadership from two hospitals with a shared pediatric code response team employed the Institute for Healthcare Improvement's (IHI) Breakthrough Model for Collaborative Improvement to design a program consisting of Plan-Do-Study-Act cycles occurring in a simulated environment. The objectives of the program were to 1) identify inefficiencies in our pediatric code response; 2) correlate to current workflow; 3) employ an iterative process to test quality improvement interventions in a safe environment; and 4) measure performance before actual implementation at the institutional level. RESULTS: Twelve dual-hospital, in-situ, simulated, pediatric emergencies occurred over one year. The initial simulated event allowed identification of inefficiencies including delayed provider response, delayed initiation of cardiopulmonary resuscitation (CPR), and delayed vascular access. These gaps were linked to process issues including unreliable code pager activation, slow elevator response, and lack of responder familiarity with layout and contents of code cart. From first to last simulation with multiple simulated process improvements, code response time for secondary providers coming from the second hospital decreased from 29 to 7 min, time to CPR initiation decreased from 90 to 15 s, and vascular access obtainment decreased from 15 to 3 min. Some of these simulated process improvements were adopted into the institutional response while others continue to be trended over time for evidence that observed changes represent a true new state of control. CONCLUSIONS: Utilizing the IHI's Breakthrough Model, we developed a simulation-based program to 1) successfully identify gaps and inefficiencies in a complex, dual-hospital, pediatric code response system and 2) provide an environment in which to safely test quality improvement interventions before institutional dissemination.

A pilot study to identify pre- and peri-operative risk factors for airway complications following adenotonsillectomy for treatment of severe pediatric OSA.

OBJECTIVE: A pilot study to identify risk factors predicting post-operative complications in children with severe OSA undergoing adenotonsillectomy. METHODS: Retrospective review in a tertiary care academic institution. Two-stage least squares regression analysis and instrumental variable analysis to allow for modeling of pre- and peri-operative risk factors as having significance in predicting post-operative morbidity. RESULTS: Eighty-three children (mean age 4.88 ± 3.09 years) with apnea-hypopnea index (AHI) ≥ 10 who were observed overnight following adenotonsillectomy were evaluated for rates of major (increased level of care, CPAP/BiPAP use, pulmonary edema and reintubation) and minor (oxygen saturation <90%) airway complications as well as total observation costs. Major and minor complications occurred in 4.8% and 19.3% of children, respectively. Age <2 years (p<0.01), AHI >24 (p<0.05), intra-operative laryngospasm requiring treatment (p<0.05), oxygen saturations <90% on room air in PACU (p<0.05) and PACU stay >100 min (p<0.01) independently predicted post-operative complications. Children with any one of these factors experienced a 38% complication rate versus 4% in all others. CONCLUSIONS: This pilot study identified pre- and peri-operative risk factors that collectively can be investigated as predictors of post-operative airway complications in a prospective study. By identifying preliminary results comparing the complication rates between those children with and without these risk factors, we will be able to calculate the sample size for a future prospective validation study. Such a study is necessary to understand the safety and potential significant cost savings of observing children without risk factors on the pediatric floor and not in an ICU setting. A best practice algorithm can be created for children with severe OSA only after completing this prospective study.

Anesthesia for pediatric airway surgery: recommendations and review from a pediatric referral center.

Pediatric airway surgery presents many significant challenges to the anesthesia provider. The clinical experience of the Massachusetts Eye and Ear Infirmary serves as a guide in this review to describe the clinical reasoning and perioperative management of the pediatric patient needing airway surgery, with specific emphasis on diagnostic procedures, trauma, laryngotracheal reconstruction, juvenile recurrent respiratory papillomatosis, and adenotonsillectomy.

Challenges in pediatric ambulatory anesthesia: kids are different.

The care of the child having ambulatory surgery presents a specific set of challenges to the anesthesia provider. This review focuses on areas of clinical distinction that support the additional attention children often require, and on clinical controversies that require providers to have up-to-date information to guide practice and address parental concerns. These include perioperative risk; obstructive sleep apnea; obesity; postoperative nausea and vomiting; neurocognitive outcomes; and specific concerns regarding common ear, nose, and throat procedures.
