Discrepancies Between the Management of Fever in Young Infants Admitted From Urban General Emergency Departments and Pediatric Emergency Departments.

INTRODUCTION/OBJECTIVE: Most pediatric emergency visits occur in general emergency departments (GED). Our study aims to assess whether medical decision making regarding the management of febrile infants differs in GEDs from pediatric EDs (PED) and deviates from pediatric expert consensus. METHODS: We conducted a retrospective chart review on patients younger than 60 days with fever admitted from 13 GEDs versus 1 PED to a children's hospital over a 3-year period. Adherence to consensus guidelines was measured by frequency of performing critical components of initial management, including blood culture, urine culture, attempted lumbar puncture, and antibiotic administration (<29 days old), or complete blood count and/or C-reactive protein, blood culture, and urine culture (29-60 days old). Additional outcomes included lumbar puncture, collecting urine specimens via catheterization, and timing of antibiotics. RESULTS: A total of 176 patient charts were included. Sixty-four (36%) patients were younger than 29 days, and 112 (64%) were 29 to 60 days old. Eighty-eight (50%) patients were admitted from GEDs.In infants younger than 29 days managed in the GEDs (n = 32), 65.6% (n = 21) of patients underwent all 4 critical items compared with 96.9% (n = 31, P = 0.003) in the PED. In infants 29 to 60 days old managed in GEDs (n = 56), 64.3% (n = 36) patients underwent all 3 critical items compared with 91.1% (n = 51, P < 0.001) in the PED. CONCLUSIONS: This retrospective study suggests that providers managing young infants with fever in 13 GEDs differ significantly from providers in the PED examined and literature consensus. Inconsistent testing and treatment practices may put young infants at risk for undetected bacterial infection.

Rapid Implementation of an Adult Coronavirus Disease 2019 Unit in a Children's Hospital.

OBJECTIVE: To describe the rapid implementation of an adult coronavirus disease 2019 (COVID-19) unit using pediatric physician and nurse providers in a children's hospital and to examine the characteristics and outcomes of the first 100 adult patients admitted. STUDY DESIGN: We describe our approach to surge-in-place at a children's hospital to meet the local demands of the COVID-19 pandemic. Instead of redeploying pediatric providers to work with internist-led teams throughout a medical center, pediatric physicians and nurses organized and staffed a 40-bed adult COVID-19 treatment unit within a children's hospital. We adapted internal medicine protocols, developed screening criteria to select appropriate patients for admission, and reorganized staffing and equipment to accommodate adult patients with COVID-19. We used patient counts and descriptive statistics to report sociodemographic, system, and clinical outcomes. RESULTS: The median patient age was 46 years; 69% were male. On admission, 78 (78%) required oxygen supplementation. During hospitalization, 13 (13%) eventually were intubated. Of the first 100 patients, 14 are still admitted to a medical unit, 6 are in the intensive care unit, 74 have been discharged, 4 died after transfer to the intensive care unit, and 2 died on the unit. The median length of stay for discharged or deceased patients was 4 days (IQR 2, 7). CONCLUSIONS: Our pediatric team screened, admitted, and cared for hospitalized adults by leveraging the familiarity of our system, adaptability of our staff, and high-quality infrastructure. This experience may be informative for other healthcare systems that will be redeploying pediatric providers and nurses to address a regional COVID-19 surge elsewhere.

COVID-19 PICU guidelines: for high- and limited-resource settings.

BACKGROUND: Fewer children than adults have been affected by the COVID-19 pandemic, and the clinical manifestations are distinct from those of adults. Some children particularly those with acute or chronic co-morbidities are likely to develop critical illness. Recently, a multisystem inflammatory syndrome (MIS-C) has been described in children with some of these patients requiring care in the pediatric ICU. METHODS: An international collaboration was formed to review the available evidence and develop evidence-based guidelines for the care of critically ill children with SARS-CoV-2 infection. Where the evidence was lacking, those gaps were replaced with consensus-based guidelines. RESULTS: This process has generated 44 recommendations related to pediatric COVID-19 patients presenting with respiratory distress or failure, sepsis or septic shock, cardiopulmonary arrest, MIS-C, those requiring adjuvant therapies, or ECMO. Evidence to explain the milder disease patterns in children and the potential to use repurposed anti-viral drugs, anti-inflammatory or anti-thrombotic therapies are also described. CONCLUSION: Brief summaries of pediatric SARS-CoV-2 infection in different regions of the world are included since few registries are capturing this data globally. These guidelines seek to harmonize the standards and strategies for intensive care that critically ill children with COVID-19 receive across the world. IMPACT: At the time of publication, this is the latest evidence for managing critically ill children infected with SARS-CoV-2. Referring to these guidelines can decrease the morbidity and potentially the mortality of children effected by COVID-19 and its sequalae. These guidelines can be adapted to both high- and limited-resource settings.

Protocol-Driven Management of Convulsive Status Epilepticus at a Tertiary Children's Hospital: A Quality Improvement Initiative.

OBJECTIVES: Convulsive status epilepticus is a medical emergency. Prompt treatment has been shown to decrease progression to refractory convulsive status epilepticus. We aimed to reduce time to second-line anti-seizure medication through implementation of a standardized treatment protocol. DESIGN: Quality improvement project. We constructed a multidisciplinary team and completed Plan-Do-Study-Act cycles to achieve the project aim. SETTING: A tertiary care children's hospital. PATIENTS: Patients presenting to the Children's Hospital at Montefiore emergency department with convulsive status epilepticus or new-onset seizures during admission to Children's Hospital at Montefiore. INTERVENTIONS: Implementation of a standardized treatment protocol, uploading the protocol to the hospital's intranet, adding anti-seizure medications to the hospital's Pyxis system, and creating a standardized convulsive status epilepticus order set in the electronic medical record. The primary outcome measure was time from order to administration of second-line anti-seizure medication, and secondary outcome was total seizure time. MEASUREMENTS AND MAIN RESULTS: Seventy-eight patients were analyzed, including 41 from the baseline period (January 2014 through June 2015) and 37 from the postintervention period (July 2015 through December 2016). The median time to administration of second-line anti-seizure medication decreased from 52 to 21 minutes (p = 0.001) and total seizure time from 65 to 31 minutes (p = 0.09). CONCLUSIONS: A standardized treatment protocol for convulsive status epilepticus decreased time to administration of second-line therapy by 60%, but there was no statistically significant decrease in total seizure time.

American College of Critical Care Medicine Clinical Practice Parameters for Hemodynamic Support of Pediatric and Neonatal Septic Shock.

OBJECTIVES: The American College of Critical Care Medicine provided 2002 and 2007 guidelines for hemodynamic support of newborn and pediatric septic shock. Provide the 2014 update of the 2007 American College of Critical Care Medicine "Clinical Guidelines for Hemodynamic Support of Neonates and Children with Septic Shock." DESIGN: Society of Critical Care Medicine members were identified from general solicitation at Society of Critical Care Medicine Educational and Scientific Symposia (2006-2014). The PubMed/Medline/Embase literature (2006-14) was searched by the Society of Critical Care Medicine librarian using the keywords: sepsis, septicemia, septic shock, endotoxemia, persistent pulmonary hypertension, nitric oxide, extracorporeal membrane oxygenation, and American College of Critical Care Medicine guidelines in the newborn and pediatric age groups. MEASUREMENTS AND MAIN RESULTS: The 2002 and 2007 guidelines were widely disseminated, translated into Spanish and Portuguese, and incorporated into Society of Critical Care Medicine and American Heart Association/Pediatric Advanced Life Support sanctioned recommendations. The review of new literature highlights two tertiary pediatric centers that implemented quality improvement initiatives to improve early septic shock recognition and first-hour compliance to these guidelines. Improved compliance reduced hospital mortality from 4% to 2%. Analysis of Global Sepsis Initiative data in resource rich developed and developing nations further showed improved hospital mortality with compliance to first-hour and stabilization guideline recommendations. CONCLUSIONS: The major new recommendation in the 2014 update is consideration of institution-specific use of 1) a "recognition bundle" containing a trigger tool for rapid identification of patients with septic shock, 2) a "resuscitation and stabilization bundle" to help adherence to best practice principles, and 3) a "performance bundle" to identify and overcome perceived barriers to the pursuit of best practice principles.

Retrospective Outcomes Comparison by Treatment Location for Pediatric Mild and Moderate Diabetic Ketoacidosis.

OBJECTIVES: Pediatric diabetic ketoacidosis (DKA) is often treated in a PICU, but nonsevere DKA may not necessitate PICU admission. At our institution, nonsevere DKA was treated on the floor until policy change shifted care to the PICU. We describe outcomes in pediatric mild to moderate DKA by treatment location. METHODS: Patients aged 2 to 21 with mild to moderate DKA (pH <7.3 but >7.1), treated on the floor from January 1, 2018 to July 31, 2020 and PICU from August 1, 2020 to October 1, 2022 were included. We performed a single-center, retrospective cohort study; primary outcome was DKA duration (from emergency department diagnosis to resolution), secondary outcomes included hospital length of stay, and complication rates, based on treatment location. RESULTS: Seventy nine floor and 65 PICU encounters for mild to moderate pediatric DKA were analyzed. There were no differences in demographics, initial pH, or bicarbonate; PICU patients had more acute kidney injury on admission. Floor patients had a shorter DKA duration (10 hours [interquartile range 7-13] vs 11 hours [9-15]; P = .04), and a shorter median length of stay (median 43.5 hours [interquartile range 31-62] vs 49 hours [32-100]; P < .01). No patients had clinical signs of cerebral edema; other complications occurred at similar rates. PICU patients received significantly more intravenous electrolyte boluses, but there were no differences in dysrhythmia or electrolyte abnormalities on final serum chemistry. CONCLUSIONS: Our study did not find a clear benefit to admitting patients with mild to moderate DKA to the PICU instead of the hospital floor. Our findings suggest that some children with nonsevere DKA may be treated safely in a non-PICU setting.

Response Time in the Transport of Pediatric Patients to a Tertiary Critical Care Unit.

Introduction: Various barriers delay the process of patient transfer to critical care units. We implemented quality improvement methods to decrease the time required for interhospital transfer of critical care patients. As a result, we aimed to decrease the time from initial transfer call to specialized transport team arrival at the referring hospital from 150 minutes to <40 minutes over 2 years. Methods: Quality improvement initiative monitoring the length of transport time of 245 patients transferred from referral hospitals to a tertiary pediatric intensive care unit for 31 months from March 2013 to October 2015. We reviewed preexisting transport protocols and identified barriers to the timely arrival to the pediatric intensive care unit. We implemented 3 interventions: a transport information line serving as a central communication center to coordinate the transport process between all stakeholders, the formation of a specialized pediatric transport team, and a training program. We collected transport response time data and monitored the impact of interventions via statistical process control charts. Results: There was a significant decrease in the length of the time course pre- and postintervention. We noted a special cause to decrease in time from referral hospital call to arrival of our transport team by 76% from 150 minutes to 36 minutes. In addition, the statistical process chart revealed a stable and effective process without significant shifts above the process mean as early as 3 months postintervention. Conclusions: By improving our transport services with additional resources and people, we have improved the efficiency of patient transport between institutions.

Ambulatory Neuromuscular Scoliosis Patients Have Superior Perioperative Results Than Nonambulatory Neuromuscular Scoliosis Patients and Can Approach Adolescent Idiopathic Scoliosis Outcomes After Posterior Spinal Fusion.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: This study aims to identify differences in perioperative outcomes between ambulatory patients with neuromuscular scoliosis (ANMS) and adolescent idiopathic scoliosis (AIS) following spinal fusion. SUMMARY OF BACKGROUND DATA: NMS patients have severe curves with more comorbidities and procedural complexity. These patients require extensive fusion levels, increased blood loss, and suffer increased periop complications. However, NMS patients have a variable severity spectrum, including ambulation status. METHODS: Chart and radiographic review of NMS and AIS patients undergoing PSF from 2005 to 2018. NNMS included NMS patients who were completely dependent (GMFCS IV-V). ANMS consisted of community ambulators without significant reliance on wheeled assistive devices (GMFCS I-III). Subanalysis matched by age, sex, levels fused and preoperative Cobb angle was conducted as well. Wilcoxon Rank-Sum, Kruskal-Wallis, χ2, and Fisher exact tests were performed. RESULTS: There were 120 patients in the NNMS group, 54 in ANMS and 158 in the AIS group. EBL was significantly lower for ANMS and AIS patients (P < 0.001). Complications within 30 days were similar between ANMS and AIS (P = 1.0), but significantly higher for NNMS (P < 0.001). Two (1.3%) AIS patients, (1.7%) nonambulatory NMS patients, and one (1.9%) ANMS patient required revision surgery (P = 1.0). However, all NMS patients had increased fusion levels, fixation points, and surgery time (P < 0.05). NNMS had significantly longer ICU (P < 0.001), hospital stay (P < 0.001), intraoperative transfusions (P < 0.001), and fewer patients extubated in the OR (P < 0.001) than ANMS and AIS patients. In the subanalysis, ANMS had similar radiographic measurements, EBL, transfusion, surgery time, extubation rate, and complication rate (P > 0.05) to AIS. CONCLUSION: Our data show radiographic outcomes, infections, revisions, and overall complications for ANMS were similar to the AIS population. This suggests that NMS patients who ambulate primarily without assistance can expect surgical outcomes comparable to AIS patients with further room for improvement in length of ICU and hospital stay.Level of Evidence: 4.

Implementation of a Critical Care Asthma Pathway in the PICU.

OBJECTIVES: Acute asthma management has improved significantly across hospitals in the United States due to implementation of standardized care pathways. Management of severe acute asthma in ICUs is less well studied, and variations in management may delay escalation and/or deescalation of therapies and increase length of stay. In order to standardize the management of severe acute asthma in our PICU, a nurse- and respiratory therapist-driven critical care asthma pathway was designed, implemented, and tested. DESIGN: Cross-sectional study of severe acute asthma at baseline followed by implementation of a critical care asthma pathway. SETTING: Twenty-six-bed urban quaternary PICU within a children's hospital. PATIENTS: Patients 24 months to 18 years old admitted to the PICU in status asthmaticus. Patients with severe bacterial infections, chronic lung disease, heart disease, or immune disorders were excluded. INTERVENTIONS: Implementation of a nurse- and respiratory therapist-driven respiratory scoring tool and critical care asthma pathway with explicit escalation/deescalation instructions. MEASUREMENTS AND MAIN RESULTS: Primary outcome was PICU length of stay. Secondary outcomes were time to resolution of symptoms and hospital length of stay. Compliance approached 90% for respiratory score documentation and critical care asthma pathway adherence. Severity of illness at admission and clinical baseline characteristics were comparable in both groups. Pre intervention, the median ICU length of stay was 2 days (interquartile range, 1-3 d) with an overall hospital length of stay of 4 days (interquartile range, 3-6 d) (n = 74). After implementation of the critical care asthma pathway, the ICU length of stay was 1 day (interquartile range, 1-2 d) (p = 0.0013; n = 78) with an overall length of stay of 3 days (interquartile range, 2-3.75 d) (p < 0.001). The time to resolution of symptoms was reduced from a median of 66.5 hours in the preintervention group to 21 hours in the postintervention compliant group (p = 0.036). CONCLUSIONS: The use of a structured critical care asthma pathway, driven by an ICU nurse and respiratory therapist, is associated with faster resolution of symptoms, decreased ICU, and overall hospital lengths of stay in children admitted to an ICU for severe acute asthma.

A dual-team approach benefits standard-volume surgeons, but has minimal impact on outcomes for a high-volume surgeon in AIS patients.

STUDY DESIGN: Retrospective chart review of prospectively collected data. OBJECTIVE: This study seeks to evaluate the effect of number of surgeons, surgeon experience, and surgeon volume on AIS surgery. Recent literature suggests that utilizing two surgeons for spine deformity correction surgery can improve perioperative outcomes. However, the surgeon's experience and surgical volume are likely as important. METHODS: AIS patients undergoing PSF from 2009 to 2019 were included. Patient demographics, X-ray and perioperative outcomes were collected and collated based on primary surgeon. Analysis was performed for single versus dual surgeons, surgeon experience (≤ 10 years in practice), and surgical volume (less/greater than 50 cases/year). Median (IQR) values, Wilcoxon Rank Sums test, Kruskal-Wallis test, and Fisher's exact test were utilized. RESULTS: 519 AIS cases, performed by 4 surgeons were included. Two surgeons were highly experienced, 1 of whom was also high volume. Five cohorts were studied: a single senior high volume (S1) (n = 302), dual-junior surgeons (DJ) (n = 73), dual senior-junior (SJ) (n = 36), dual-senior (DS) (n = 21) and a single senior, standard-volume surgeon alone (S2) (n = 87). Radiographic parameters were similar between the groups (p > 0.05). Preoperative Cobb was significantly higher for DS compared to S1 (p = 0.034) Pre- and post-op kyphosis were similar (p > 0.05). Cobb correction was similar (p > 0.05). Levels fused, fixation points, anesthesia and surgical times were similar (p > 0.05). When the standard-volume surgeon operated with a second surgeon, radiographic parameters were similar (p > 0.05), but anesthesia time, surgical time, and hospital length of stay were significantly shorter (p < 0.05). Additionally, DJ had significantly shorter anesthesia and operative times (p < 0.001) and length of stay (p < 0.001) compared to S2. CONCLUSION: Standard-volume surgeons have better outcomes with a dual surgeon approach. Junior surgeons benefit operating with an experienced surgeon. A high-volume surgeon, however, does not benefit from a dual surgeon approach. LEVEL OF EVIDENCE: Level II.

Back-to-Back Surgeries in AIS Patients Can be Performed Safely Without Compromising Radiographic or Perioperative Outcomes: A 10-year Review.

STUDY DESIGN: A retrospective chart review of prospectively collected data. OBJECTIVE: The aim of this study was to determine whether back-to-back scoliosis surgeries can be performed safely without compromising outcomes and the reproducibility of the practice between institutions. SUMMARY OF BACKGROUND DATA: During the summer, spinal surgeons will often book multiple cases in one day. The complexity and demands of spinal fusion surgery call into question the safety. Change of operating room staff including anesthesiologists, nurses, and neurologists may introduce new risks. METHODS: From 2009 to 2018, index AIS surgeries were included. In Groups 1, 2, and 3, surgeries were performed by a single surgeon. In Group 4, they were performed by other institutional surgeons. Group 1: first surgery of the day, Group 2: second surgery of the day, Group 3: only surgery of the day, Group 4: only surgery of the day by different institutional surgeon. Additional analysis was done to determine reproducibility after a surgeon was moved from Institution 1 to Institution 2. RESULTS: Five hundred sixty-seven AIS patients were analyzed. Group 1 patients had similar radiographic outcomes compared with Group 2 (P > 0.05). Surgical time was similar (P = 0.51), but significantly more levels fused (P = 0.01). Compared with Group 3, Group 2 had a smaller preoperative Cobb (P = 0.02), shorter surgeries (P < 0.001), and length of stay (P = 0.04) but similar complication rate (P = 1). Compared with Group 4, Group 2 had smaller preoperative Cobb (P < 0.001), shorter surgery, and lower complication rate (P = 0.03). When determining reproducibility, institution 2 patients had significantly less blood loss, shorter surgeries, and shorter lengths of stay (P < 0.05). CONCLUSION: Although long and involved, back-to-back AIS surgeries do not compromise radiographic or perioperative outcomes. Changes in operating team do not appear to impact safety, efficiency, or outcomes. This study also found that the practice is reproducible between institutions. LEVEL OF EVIDENCE: 3.

Pediatric Care in the Nonpediatric Emergency Department: Provider Perspectives.

OBJECTIVES: Most pediatric emergency visits are to nonpediatric emergency departments (EDs), and little is known about provider comfort level with pediatric patients. We aimed to assess providers' comfort level caring for pediatric patients of different age groups and perceived resources and barriers to delivering evidence-based pediatric care. METHODS: We conducted an anonymous electronic survey of providers (physicians, nurse practitioners, and physician assistants) in nonpediatric EDs in an urban area who admit to a single quaternary-care children's hospital. Questions addressed provider comfort in examining, diagnosing, and treating patients across 4 age groups; access to management guidelines; resources for education; and benefits of feedback from inpatient providers. Comfort was assessed with a 5-point Likert scale, with "comfortable" being defined as a 4 or 5. The association between patient age and provider comfort was analyzed by using logistic regression with generalized estimating equations. RESULTS: We surveyed 375 providers. Our response rate was 26% (14% nurse practitioners, 34% physician assistants, and 51% physicians). Of respondents, <50% report being comfortable caring for patients <3 months of age (46% examining, 38% diagnosing, 46% treating). Thirteen percent found it mostly or very easy to keep up with pediatric management guidelines (n = 12); cited barriers were time constraints, a lack of access to journals or pediatric experts, and low institutional priority due to low pediatric volume. CONCLUSIONS: This study suggests that nonpediatric ED providers' comfort in caring for pediatric patients decreases with decreasing patient age. Less than half of providers report that they are comfortable managing patients <3 months old.

Predictors of inadequate initial echocardiography in suspected Kawasaki disease: Criteria for sedation.

OBJECTIVE: Kawasaki disease is the primary cause of acquired pediatric heart disease in developed nations. Timely diagnosis of Kawasaki disease incorporates transthoracic echocardiography for visualization of the coronary arteries. Sedation improves this visualization, but not without risks and resource utilization. To identify potential sedation criteria for suspected Kawasaki disease, we analyzed factors associated with diagnostically inadequate initial transthoracic echocardiography performed without sedation. DESIGN: This retrospective review of patients < 18 years old undergoing initial transthoracic echocardiography for the inpatient evaluation of suspected Kawasaki disease from 2009 to 2015 occurred at a medium-sized urban children's hospital. The primary outcome was diagnostically inadequate transthoracic echocardiography without sedation due to poor visualization of the coronary arteries, determined by review of clinical records. The associations of the primary outcome with demographics, Kawasaki disease type, laboratory data, fever, and antipyretic or intravenous immunoglobulin treatment prior to transthoracic echocardiography were analyzed. RESULTS: In total, 112 patients (44% female, median age 2.1 years, median BSA 0.54 m2 ) underwent initial transthoracic echocardiography for suspected Kawasaki disease, and 99 were not sedated. Transthoracic echocardiography was diagnostically inadequate in 19 out of these 99 patients (19.2%) and was associated with age ≤ 2.0 years, weight ≤ 10.0 kg, and antipyretic use ≤ 6 hours before transthoracic echocardiography (all P < .05). These variables did not reach statistical significance on multivariable analysis. CONCLUSIONS: Patients ≤ 2.0 years or ≤ 10.0 kg or those recently receiving antipyretics, potentially a surrogate for irritability, were associated with diagnostically inadequate transthoracic echocardiography during the inpatient workup of Kawasaki disease. These factors should be considered when deciding which patients to sedate for initial Kawasaki disease transthoracic echocardiography.

Mortality before and after initiation of a computerized physician order entry system in a critically ill pediatric population.

OBJECTIVE: A worrisome increase in mortality has been reported recently following the initiation of a computerized physician order entry (CPOE) system in a critically ill pediatric transport population. We tested the hypothesis that such a mortality increase did not occur after the initiation of CPOE in a pediatric population that was directly admitted to the neonatal and pediatric intensive care units at Montefiore Medical Center during two 6-month periods before CPOE and one 6-month period immediately after CPOE was initiated. Mortality in the pre- and post-CPOE time periods was compared, and adjustment for potentially confounding covariates was performed. SETTING: The pediatric and neonatal intensive care units at Montefiore Medical Center. PATIENTS: All patients admitted from the emergency room or operating room or as transfers from other institutions directly to the pediatric and neonatal intensive care units at Montefiore Medical Center. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Overall, 29 (3.16%) of the 917 patients in the pre-CPOE period and nine (2.41%) of the 374 patients in the post-CPOE period died during their hospital stay (p = .466). The power to detect the hypothesized mortality increase was 81.7%. The variables that remained significant risk factors for mortality after adjustment were shock (odds ratio, 9.41; 95% confidence interval, 2.90-30.49), prematurity (odds ratio, 3.57; 95% confidence interval, 1.74-7.30), male gender (odds ratio, 3.31; 95% confidence interval, 1.47-7.69), or a hematologic/oncologic diagnosis (odds ratio, 3.14; 95% confidence interval, 1.44-6.86). Post-CPOE initiation status remained unassociated with mortality after adjusting for all covariates (odds ratio, 0.71; 95% confidence interval, 0.32-1.57). CONCLUSION: Mortality did not increase during CPOE initiation.

Spinal Fusion for Scoliosis in Rett Syndrome With an Emphasis on Respiratory Failure and Opioid Usage.

Our objective was to characterize our experience with 8 patients with Rett syndrome undergoing scoliosis surgery in regard to rates of respiratory failure and rates of ventilator-acquired pneumonia in comparison to patients with neurologic scoliosis and adolescent idiopathic scoliosis. This study was a retrospective chart review of patients undergoing scoliosis surgery at a tertiary children's hospital. Patients were divided into 3 groups: (1) adolescent idiopathic scoliosis, (2) neurologic scoliosis, and (3) Rett syndrome. There were 133 patients with adolescent idiopathic scoliosis, 48 patients with neurologic scoliosis, and 8 patients with Rett syndrome. We found that patients with Rett syndrome undergoing scoliosis surgery have higher rates of respiratory failure and longer ventilation times in the postoperative period when compared with both adolescent idiopathic scoliosis and neurologic scoliosis patients. There is insufficient evidence to suggest a difference in the incidence of ventilator-acquired pneumonia between the Rett syndrome and the neurologic scoliosis group. We believe our findings are the first in the literature to show a statistically significant difference between these 3 groups in regard to incidence of respiratory failure.

Increased Risk of Infection in Obese Adolescents After Pedicle Screw Instrumentation for Idiopathic Scoliosis.

STUDY DESIGN: Original research. OBJECTIVE: To evaluate perioperative risk factors associated with obesity in children undergoing posterior spinal fusion for adolescent idiopathic scoliosis. The authors hypothesized that patients with a high body mass index (BMI) percentile would be associated with increased morbidity as measured by various intraoperative parameters. SUMMARY OF BACKGROUND DATA: Few studies have evaluated the effects of increased BMI in children undergoing surgery. Adolescent idiopathic scoliosis represents 80% of idiopathic scoliosis cases and is the most common indication for surgery. METHODS: Patients were divided into 3 groups: normal weight (n = 144) (5% < BMI < 85%), overweight (n = 25) (BMI > 85% to 95%), and obese (n = 38) (BMI > 95%). Patients with BMI less than 5% were excluded from this study because they were underweight. Perioperative data were collected and analyzed based on differences between groups. RESULTS: A total of 207 patients were included in this study. There was a significant difference in the length of anesthesia (p = .032). The rate of infection was 11% in the obese group, 12% in the overweight group, and 3% in the normal weight group (p = .03). CONCLUSIONS: Even with pedicle screw instrumentation, the researchers saw an increase in infection in overweight and obese patients. Patients should be counseled before surgery for weight loss to limit surgical complications such as possible risk of postoperative wound infection.

Minimally Invasive Scoliosis Surgery: A Novel Technique in Patients with Neuromuscular Scoliosis.

Minimally invasive surgery (MIS) has been described in the treatment of adolescent idiopathic scoliosis (AIS) and adult scoliosis. The advantages of this approach include less blood loss, shorter hospital stay, earlier mobilization, less tissue disruption, and relatively less pain. However, despite these significant benefits, MIS approach has not been reported in neuromuscular scoliosis patients. This is possibly due to concerns with longer surgery time, which is further increased due to more levels fused and instrumented, challenges of pelvic fixation, size and number of incisions, and prolonged anesthesia. We modified the MIS approach utilized in our AIS patients to be implemented in our neuromuscular patients. Our technique allows easy passage of contoured rods, placement of pedicle screws without image guidance, partial/complete facet resection, and all standard reduction maneuvers. Operative time needed to complete this surgery is comparable to the standard procedure and the majority of our patients have been extubated at the end of procedure, spending 1 day in the PICU and 5-6 days in the hospital. We feel that MIS is not only a feasible but also a superior option in patients with neuromuscular scoliosis. Long-term results are unavailable; however, short-term results have shown multiple benefits of this approach and fewer limitations.
