Objective To evaluate the efficacy of dexmedetomidine as an opioid-sparing agent in infants following open thoracic or abdominal operations. Methods Retrospective review of postoperative neonates who received IV acetaminophen with or without dexmedetomidine. The primary outcome was opioid dosage within the first ten postoperative days. Secondary outcomes included times to extubation, full feedings and discharge. Results 112 infants met inclusion criteria. Those managed with dexmedetomidine received 1.8-4.3 times more opioid on postoperative days 1-3, had longer times to extubation and trended towards longer lengths of hospital stay than infants who were not. Opioid was dosed >0.2 ME/kg on only 23% of days when the acetaminophen dose was >40 mg/kg/day and 10% of days when the acetaminophen dose was >45 mg/kg. Conclusion Dexmedetomidine may not be opioid sparing after major operations in neonates and its use delays recovery. IV acetaminophen dosed at 40 mg/kg/day or greater may yield the most substantial opioid-sparing effect.

Objective The use of standing electronic scooters associated with micromobility applications (e-scooters) has risen nationally. The aim of this study was to obtain a detailed view of soft tissue and bony craniofacial injury associated with e-scooter-related trauma. Methods Single-institution retrospective case series of patients presenting to a level 1 trauma center emergency department or trauma unit with documented e-scooter-related craniofacial injury. Results Of 203 included patients, 188 (92.6%) patients sustained craniofacial injury. One hundred thirty-one (64.5%) had exclusively soft tissue injury, 3 (1.5%) exclusively bony injury, 51 (25.1%) both soft and bony injuries, and twenty-five (12.3%) patients sustained dental injury. Aesthetic units most frequently sustaining acute soft tissue injury were the forehead (n = 106, 34.6%), scalp (n = 36, 11.8%), chin (n = 34, 11.1%), upper lip (n = 32, 10.5%), and cheek (n = 31, 10.1%). Aesthetic subunits most often sustaining acute soft tissue injury included the brow (42, 13.7%), central forehead (39, 12.7%), lateral forehead (n = 25, 8.2%), and upper lip vermillion (n = 23, 7.5%). Craniofacial osseous fracture most often occurred in the orbit (n = 42, 24.6%) and maxilla (n = 40, 23.4%). Individual osseous segments most frequently sustaining acute fracture included the anterior maxillary sinus wall (n = 22, 12.9%), nasal bone (n = 20, 11.7%), lateral orbital wall (n = 16, 9.4%), orbital floor (n = 15, 8.8%), and zygomatic bone (13, 7.6%). Conclusions Our analysis demonstrates that most patients presenting to our center with craniofacial trauma sustained acute bony fracture, most often to the midface. Our data of common injuries associated with e-scooter trauma could inform implementation in the form of facial safety equipment or safety skills training for e-scooter riders. Level of evidence 4.

BACKGROUND The impact of metopic craniosynostosis on intracranial volume (ICV) and ICV growth is unclear. In addition, the relationship between head circumference (HC) and ICV in these patients is not previously described. METHODS A retrospective review of 72 patients with metopic craniosynostosis was performed. The ICVs were calculated from manually segmented preoperative computed tomography scans. Magnetic resonance imaging data for 270 healthy children were available. The ICVs were calculated in FreeSurfer.First, a growth curve for metopic patients was generated and a logarithmic best-fit curve was calculated. Second, the impact of metopic craniosynostosis on ICV relative to healthy controls was assessed using multivariate linear regression. Third, the growth curves for metopic patients and healthy children were compared.Pearson's correlation was used to measure the association between HC and ICV. RESULTS Mean metopic ICV was significantly lower than normal ICV within the first 3 to 6 months (674.9 versus 813.2 cm; P = 0.002), 6 to 9 months (646.6 versus 903.9 cm; P = 0.005), and 9 to 12 months of life (848.0 versus 956.6 cm; P = 0.038). There was no difference in ICV after 12 months of age (P = 0.916).The ICV growth in patients with metopic craniosynostosis is defined by a significantly different growth curve than in normal children (P = 0.005).The ICV and HC were highly correlated across a broad range of ICVs and patient age (r = 0.98, P

BACKGROUND Prior studies have shown a lack of diversity among plastic surgery trainees. The authors evaluate trends in minority representation among applicants to plastic surgery and the correlation with practicing residents, compared to other specialties. METHODS The Association of American Medical Colleges Electronic Residency Application Service provided applicant data for integrated, independent plastic surgery, and other select specialties from 2010 to 2016. Journal of the American Medical Association Graduate Medical Education annual reports and Association of American Medical Colleges graduate student questionnaires provided resident and medical student data. Binomial distribution analysis was used to assess differences in Black, Hispanic, and female proportions of applicants and residents. Best-fit trend lines were compared among groups and specialties. RESULTS Women have seen an increase in integrated and independent resident representation (+2.23 percent and +0.7 percent per year, respectively) over the past 7 years, despite a relative decrease in applicants. The proportion of female applicants and residents correlated yearly for all specialties (p > 0.05). Conversely, for all years and all specialties, the Black proportion of applicants was significantly higher than the resident representation of the same year (p < 0.05). Hispanic applicant and resident representation have seen a minimal change. CONCLUSIONS Female representation among trainees has increased greatly, but there has been a decline in Black representation of integrated plastic surgery residents despite increases in medical school graduates and applicants. The data highlight a discrepancy between the population of applicants and residents suggesting that barriers starting from medical school may contribute to the lack of diversity in plastic surgery.

Purpose Maximizing operating room (OR) efficiency is essential for hospital cost containment and effective patient throughput. Little data is available regarding the safety and efficacy of extubation of children in the post-anesthesia care unit (PACU) by a nurse rather than in the OR. We sought to evaluate the impact of a long-standing practice of PACU extubation upon airway complications and OR efficiency. Methods The records of 1930 children who underwent inguinal hernia repair, laparoscopic appendectomy or pyloromyotomy at a children's hospital between July, 2018 and June, 2020 were reviewed. Extubations were performed in the OR only when the PACU was inadequately staffed or during the early months of the Covid-19 pandemic. Cases in which there was a deep extubation, a PACU hold was in effect or a patient went directly to an inpatient unit from the OR were excluded. Intra- and post-operative time metrics were recorded and emergency airway interventions were assessed. Results 1747 operations were evaluated. Time from the end of the procedure to leaving the OR ranged from 4.1 to 4.8 min when extubation was done in the PACU and was 6-9 min less than with OR extubation. (see table). There were 23 airway events (1.5% of all cases) after PACU extubation that necessitated only brief bag-mask ventilation. There were no cases of re-intubation. Conclusions In a large population of children undergoing diverse surgical procedures, post-anesthesia care unit extubation was safe and resulted in rapid transfer of patients from the operating room after completion of their operation. Time saved because of shorter operating room times reduces hospital costs and can allow for increased throughput. Extubation in the post-anesthesia care unit may not only be as safe as operating room extubation, but may result in fewer serious airway events as patients may be less likely to have their endotracheal tube removed prematurely.

Medical students pursuing plastic surgery training must overcome multiple challenges to successfully match in such a highly coveted subspecialty. This adversity is amplified in applicants from medical schools without a home plastic surgery residency program and academic division. There is a paucity of data on the advantage of medical students applying from an institution with a home residency program. Applicant data from the past 5 years were accessed from the Association of American Medical Colleges Electronic Residency Application Services statistics form. Individual home programs of successfully matched applicants were collected from plastic surgery residency websites. A survey was distributed to 32 students pursuing specialty residencies from home medical schools without a plastic surgery residency. Evaluation of a subset of incoming plastic surgery interns revealed that 72% of matched applicants attended home medical institutions with plastic surgery residency programs. Seventy-seven percent of survey respondents felt strongly that students at institutions with home residency programs had a significant advantage. The current COVID pandemic is changing the landscape of subinternships and bringing to light the disadvantage students face without home residency programs. The development of virtual subinternships, online mentorship, and selection of students for subinternships from geographic areas without home programs may help address some disparities in educational opportunities. Continuing these virtual programs and offering preferential help to disadvantaged medical students permanently is an avenue for the field of plastic surgery to be a leader in diversity and inclusion.

Objective: Masses of the sternoclavicular area are rare, and are not well described in the literature. We aim to present a series of patients with masses in this location and to review all reported English language cases of sternoclavicular masses in pediatric patients. Methods: This is a case series of pediatric patients with masses of the sternoclavicular area presenting to a tertiary care pediatric hospital from 2010 through 2017. Data was collected by using ICD-9 and ICD-10 codes to query the electronic medical record. Chart review included age at presentation, mass characteristics, medical and surgical interventions, and pathology results. A review of the literature was then performed. Results: Ten patients with masses overlying the sternoclavicular area were identified. Four patients presented with abscess and were treated with incision and drainage. Three of these patients were then treated with staged excision once infection cleared. Two additional patients were treated with primary excision. Four patients were treated with observation. The most common histopathologic finding was epidermoid. One patient was found to have a dermoid cyst, and 1 had a congenital cartilaginous rest. Conclusion: Epidermoids and dermoids are the most common masses overlying the sternoclavicular area. Controversy remains regarding the embryologic origin of sternoclavicular masses. The differential for masses in this area also includes branchial remnants, bronchogenic cysts, ganglion cysts, or septic arthritis.

Introduction: Operating room (OR) throughput and efficiency is a key driver of hospital costs. We sought to evaluate the efficacy, safety, and cost implications of a practice of post-anesthesia care unit (PACU) extubation for 4 common pediatric surgical operations. Methods: The records of 6,956 children who underwent inguinal hernia repair, laparoscopic appendectomy, pyloromyotomy, and tonsillectomy/adenoidectomy at a free-standing children’s hospital between July 2018 and June 2020 were reviewed. OR flow time metrics and postoperative airway interventions were assessed. Based on a 2014 study, 1 minute of operative time was assessed at $37. Exclusion criteria included PACU holds and direct transfers from the OR to an inpatient unit. Results: There were 5,245 procedures analyzed. All patients were extubated in the PACU except during periods of elevated COVID-19 transmission risk or when the PACU was understaffed. The mean time from procedure completion to leaving the OR was between 3.7 and 4.8 minutes for patients extubated in the PACU and 10.0 and 13.0 minutes for those extubated in the OR. PACU respiratory events were minor, infrequent, and of similar incidence after PACU or OR extubation. Conclusion: We found PACU extubation to be safe and effective in reducing patient time in the OR by up to 13 minutes. We project that our hospital has saved more than $1 million in 2 years due to the time savings associated with only these 4 common operations. In a time of limited resources, a policy of PACU extubation could have a substantial impact on the financial viability of children’s hospitals.

Opioid was dosed0.2 ME/kg on only 23% of days when the acetaminophen dose was40 mg/kg/day and 10% of days when the acetaminophen dose was45 mg/kg.Dexmedetomidine may not be opioid sparing after major operations in neonates and its use delays recovery. IV acetaminophen dosed at 40 mg/kg/day or greater may yield the most substantial opioid-sparing effect.

Objective: The purpose of this study is to use imaging data to determine if endoscopic endonasal surgery (EES) for skull base tumor resection interrupts skull base growth and development, resulting in an atrophic midface skeletal structure, compared to matched normal controls. Methods: Data were collected by a retrospective chart review done on children aged 16 years and below who underwent endoscopic tumor resection and had pre- and postoperative magnetic resonance imaging with relevant midface anatomy. 121 normal controls were matched to 20 EES patients by age and gender. Three measurements related to midface anatomy were taken from 1 sagittal T1 slice and 1 axial T2 slice of each scan. Statistical analysis was used to compare growth measures between cases and controls. Results: Twenty patients who underwent EES between November 2015 and April 2018 met our inclusion criteria. The mean age of the patients, 11 males and 9 females, was 10 years, and 8 patients (38%) were aged 7 years or younger. Six patients who had a high-flow CSF leak obtained a nasoseptal flap. A student T test and multivariate regression analysis found that EES did not affect midface and skull base growth. Among the variables assessed, age appears to be the only driver of growth. Conclusion: There were no identified differences in craniofacial growth in pediatric patients undergoing EES for skull base tumor resection as compared to the control group. EES does not appear to significantly interfere with midface/skull base development and is a good surgical option for pediatric patients.

Objective The purpose of this study is to specifically assess pediatric patients with nonpneumatized sphenoid sinuses who have undergone transsphenoidal resections of skull base tumors and assess the complications and outcomes. Methods Data was collected by a retrospective chart review done on children ages 7 and under who underwent endoscopic tumor resection and had a partially or completely nonpneumatized sphenoid sinus on preoperative computed tomography imaging. Surgical data collected included surgical corridor, gross total versus subtotal resection, repair method, use of septal flap, intraoperative and postoperative cerebrospinal fluid leak, and estimated blood loss. Results Six patients were identified that fit our inclusion criteria who underwent surgery between November 2015 and April 2018 (3 males, 3 females; average age = 4.28 years). Tumor pathologies include three craniopharyngiomas, Rathke cleft cyst, meningocele, and neuroblastoma. All cases involved varying percentages of sphenoid sinus pneumatization. All cases except one craniopharyngioma and the neuroblastoma required removal of cancellous bone to access pathology. Degree of sphenoid pneumatization tended to be greater with age and resulted in less intraoperative bleeding. The two youngest patients with completely nonpneumatized sphenoid sinuses lost 61.73 and 17.52% of their total blood volume intraoperatively. Procedures were able to be adequately performed and pathology completely addressed with minimal postoperative complications and no postoperative CSF leaks. Conclusions Intraoperative challenges including hemorrhage are likely in nonpneumatized patients, and thus surgeons should be prepared with adequate vascular access and blood products. Hemorrhage and total blood volume loss are increased in the younger patients with no sphenoid pneumatization. Despite the additional challenges, a nonpneumatized sphenoid sinus is not a contraindication for an endoscopic resection in the pediatric population.

526 Background: The impact of COVID-19 on cancer patients may be attributed not only to its direct effects on the immune system but also to delays in diagnosis and treatment. Data on the effects of COVID-19 on pancreatic ductal adenocarcinoma (PDAC) patients are scarce. Therefore, we set out to determine the impact of the pandemic on diagnosis and treatment initiation. We hypothesized that time from diagnosis to treatment would be increased in the COVID era compared to the pre-COVID era. Methods: We conducted an IRB-approved retrospective chart review of 488 patients diagnosed with PDAC from March 2019 to September 2020 at two academic medical centers. Patients were divided into two groups, based on the date of initial pathologic diagnosis. We defined the pre-COVID era as March 2019 to March 2020, the 12-month time period before California’s statewide lockdown. The COVID era was defined as the 6 months following the lockdown, March 2020 to September 2020. Demographics, clinical stage, and treatment type were recorded. In addition, initial clinical encounter date, pathologic diagnosis date, and initial treatment date were also collected. All data were gathered at two large-scale academic institutions. Descriptive statistics were used in the analysis. Results: There were 333 patients diagnosed during the pre-COVID era and 155 patients during the COVID era. While race/ethnicity and age at diagnosis were statistically similar for both groups, females made up a significantly larger proportion of COVID era patients than pre-COVID era patients ( p= 0.02). There was no significant difference in clinical stage at diagnosis between the two groups ( p= 0.84). In the pre-COVID era, 19.5% of cases were resectable, 11.1% borderline resectable, 20.1% locally advanced, and 31.8% metastatic. In the COVID era, 17.4% of patients were resectable, 11% borderline resectable, 23.9% locally advanced, and 32.9% metastatic. Median time from pathologic diagnosis to initiation of treatment was 32 days for the pre-COVID era patients and 28 days for the COVID era patients ( p= 0.38). Initial treatment type was also similar between the two groups ( p= 0.29). Conclusions: Fortunately, our data indicate that the COVID-19 pandemic has not significantly prevented PDAC patients from seeking care. Additionally, it does not appear that COVID-19 has delayed treatment initiation or changed initial treatment type. We believe that the successful adoption of telemedicine and other safety protocols have allowed patients with PDAC to continue receiving appropriate care during the pandemic.[Table: see text]
