Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) Use in Pediatric Procedures
THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) refers to the use of high-flow nasal cannula to augment the ability to oxygenate and ventilate a patient under general anesthesia. The use of high-flow nasal cannula oxygen supplementation during anesthesia for surgical procedures has been a recent development in the adult population, with limited data analyzing the pediatric population. This study will determine whether high flow nasal cannula oxygen supplementation during surgical or endoscopic procedures can safely prevent desaturation events in children under anesthesia.
VR Usage in Non-Invasive Surgical Sub-Specialty Procedures
Preprocedural, preoperative, and prevascular access anxiety in pediatric patients has been previously shown to increase the likelihood of family stressors, agitation, sleep disturbances, and negative behavioral changes. The purpose of this study is to determine if a non-invasive distracting device (Virtual Reality (VR) headset, Augmented Reality (AR) headset, or bed mounted Video Projection unit (i.e. BERT, Bedside EnterRtainment Theater)) is more effective than the standard of care (i.e., no technology based distraction) for preventing anxiety before non-invasive surgical sub-specialty procedures among children during out-patient clinic visits. Examples of the most common procedures include, but are not limited to gastrostomy tube exchanges, suture removals, dressing changes, foley insertions, EEG set up, chest tube removals, cast removals, pin removals and other similar procedures. (The investigators refer to these procedures under an umbrella term of non-invasive surgical subspecialty procedures). The anticipated primary outcome will be reduction of child's anxiety during and after procedures.
Evaluation of Technology-Based Stress Reduction Techniques Prior to Vascular Access
Preprocedural, preoperative, and prevascular access anxiety in pediatric patients has been previously shown to increase the likelihood of family stressors, postoperative pain, agitation, sleep disturbances, and negative behavioral changes. The purpose of this study is to determine if a non-invasive distracting devices (Virtual Reality headset) is more effective than the standard of care (i.e., no technology based distraction) for preventing anxiety before vascular access among hospitalized children undergoing vascular access prior to anesthesia, procedures, surgery, blood draws, port access, or peripheral IV placement. The anticipated primary outcome will be reduction of child's anxiety during and after vascular access.

Screen-Based Distraction Tool for Preoperative Preparation
Preoperative anxiety in pediatric patients undergoing surgical procedures has been previously shown to increase the likelihood of family stressors, post- operative pain, agitation, sleep disturbances, and negative behavioral changes. The purpose of this study is to determine whether the use of a bed mounted Video Projection unit (i.e. BERT, Bedside EnterRtainment Theater) is more effective than the use of a standard of care tablet (i.e., iPad) for preventing anxiety before surgery among children undergoing anesthesia and surgery. The anticipated primary outcome will be reduction of child's anxiety in the preoperative and operating room setting and compliance with mask induction.

Varying Screen Size for Passive Video Distraction During Induction of Anesthesia in Low Risk Children: A Pilot Randomized Controlled Trial.
BACKGROUND: Preoperative anxiety affects up to 65% of children who undergo anesthesia induction and often results in uncooperative behaviour. Electronic devices have been used to distract children to reduce anxiety and create a more enjoyable preoperative experience. Few studies have compared the effects of different video delivery systems on preoperative anxiety.AIM: The primary aim was to determine if a large projection based video screen mounted to a patient's bed decreased anxiety when compared to a tablet during mask induction of anesthesia in children from 4-10 years of age.METHODS: We performed a prospective, randomized trial to determine differences in our primary outcome, preoperative anxiety, between the large Bedside Entertainment and Relaxation Theater (BERT) and a smaller tablet screen. Secondary outcomes included 1) induction compliance, 2) child fear, 3) frequency of emergence delirium, and 4) satisfaction.RESULTS: In examining the primary outcome for 52 patients, there was a main effect for time on mYPAS scores, f(2, 51)=13.18, p<0.01. mYPAS scores significantly increased across time for both groups. The interaction for time (T0, T1 or T2) x group (BERT vs. Tablet) was not significant, f(2, 51)=1.96, p=0.15; thus changes in mYPAS scores across time did not differ by group status. There was no significant difference in induction compliance, child fear, emergence delirium, or satisfaction between the two groups.CONCLUSION: In a low risk population, preoperative anxiety was low and induction compliance was high when pairing screen based distraction interventions, regardless of size, with parental presence at induction of anesthesia.

Speeding the Detection of Vessel Cannulation: An In-Vitro Stimulation Study.
Anesthesia and analgesia
BACKGROUND: Some practitioners "prime" small IV angiocatheter needles with 0.9% sodium chloride-claiming this modification speeds visual detection of blood in the angiocatheter flash chamber on vessel cannulation.METHODS: We compared the time required for human blood to travel the length of saline-primed and saline-unprimed 24- and 22-gauge angiocatheter needles (Introcan Safety IV Catheter; B. Braun, Bethlehem, PA). A syringe pump (Medfusion 4000, Cary, NC) advanced each angiocatheter needle through the silicone membrane of an IV tubing "t-piece" (Microbore Extension Set, 5 Inch; Hospira, Lake Forest, IL) filled with freshly donated human blood. When the angiocatheter needle contacted the blood, an electrical circuit was completed, illuminating a light-emitting diode. We determined the time from light-emitting diode illumination to visual detection of blood in the flash chamber by video review. We tested 105 saline-primed angiocatheters and 105 unprimed angiocatheters in the 24- and 22-gauge angiocatheter sizes (420 catheters total). We analyzed the median time to visualize the flash using the nonparametric Wilcoxon rank sum test in R (http://www.R-project.org/). The Stanford University Administrative Panel on Human Subjects in Medical Research determined that this project did not meet the definition of human subjects research and did not require institutional review board oversight.RESULTS: In the 24-gauge angiocatheter group, the median (and interquartile range) time for blood to travel the length of the unprimed angiocatheter needle was 1.14 (0.61-1.47) seconds compared with 0.76 (0.41-1.20) seconds in the saline-primed group (P = 0.006). In the 22-gauge catheter group, the median (interquartile range) time for blood to travel the length of the unprimed angiocatheter needle was 1.80 (1.23-2.95) seconds compared with 1.46 (1.03-2.54) seconds in the saline-primed group (P = .046).CONCLUSIONS: These results support the notion that priming small angiocatheter needles, in particular 24-gauge catheters, with 0.9% sodium chloride may provide earlier detection of vessel cannulation than with the unprimed angiocatheter.

A Retrospective Review of a Bed-mounted Projection System for Managing Pediatric Preoperative Anxiety.
Pediatric quality & safety
2018; 3 (4): e087
Introduction: Most children undergoing anesthesia experience significant preoperative anxiety. We developed a bedside entertainment and relaxation theater (BERT) as an alternative to midazolam for appropriate patients undergoing anesthesia. The primary aim of this study was to determine if BERT was as effective as midazolam in producing cooperative patients at anesthesia induction. Secondary aims reviewed patient emotion and timeliness of BERT utilization.Methods: We conducted a retrospective cohort study of pediatric patients undergoing anesthesia at Lucile Packard Children's Hospital Stanford between February 1, 2016, and October 1, 2016. Logistic regression compared induction cooperation between groups. Multinomial logistic regression compared patients' emotion at induction. Ordinary least squares regression compared preoperative time.Results: Of the 686 eligible patients, 163 were in the BERT group and 150 in the midazolam. Ninety-three percentage of study patients (290/313) were cooperative at induction, and the BERT group were less likely to be cooperative (P = 0.04). The BERT group was more likely to be "playful" compared with "sedated" (P < 0.001). There was a reduction of 14.7 minutes in preoperative patient readiness associated with BERT (P = 0.001).Conclusions: Although most patients were cooperative for induction in both groups, the midazolam group was more cooperative. The BERT reduced the preinduction time and was associated with an increase in patients feeling "playful."

Contralateral osteotomy of the pedicle and posterolateral elements for en bloc resection: a technique for oncological resection of posterolateral spinal tumors
JOURNAL OF NEUROSURGERY-SPINE
2017; 26 (3): 275-281
En bloc resection of tumors involving the spinal column is technically challenging and is associated with high morbidity to the patient due to the proximity of critical neurological and vascular structures and the destabilizing nature of this surgery. Nevertheless, evidence has shown improved progression-free survival with en bloc resection for certain low-grade malignant and aggressive benign musculoskeletal tumors. To avoid the morbidity of en bloc spondylectomy in patients with tumors localized to the lateral and posterolateral spinal column, the authors have found that the goals of surgery can be accomplished through a contralateral osteotomy of the pedicle and posterolateral elements for en bloc resection (COPPER). They reviewed their series of 5 patients who underwent successful tumor removal through a COPPER approach. These patients were all found to harbor spinal column tumors involving the posterolateral elements that, based on pathology, would benefit from en bloc resection. Tumor pathology included chondrosarcoma, leiomyosarcoma, osteoblastoma, and liposarcoma. Resections were performed by completing ipsilateral facetectomies above and below the lesion and ipsilateral pedicle osteotomies from a contralateral approach following hemilaminectomy. By disarticulating the posterolateral elements while carefully protecting the thecal sac, the tumors were removed en bloc along with the affected lamina, pedicles, pars interarticularis, and spinous processes, allowing tumor-free margins. This technical report suggests that the COPPER approach is safe and effective for en bloc resection of tumors involving the posterolateral aspect of the spinal column with tumor-free margins and that it eliminates the need for anterior column reconstruction.

Initial clinical outcomes of audiovisual-assisted therapeutic ambience in radiation therapy (AVATAR).
Practical radiation oncology
Radiation therapy is an important component of treatment for many childhood cancers. Depending upon the age and maturity of the child, pediatric radiation therapy often requires general anesthesia for immobilization, position reproducibility, and daily treatment delivery. We designed and clinically implemented a radiation therapy-compatible audiovisual system that allows children to watch streaming video during treatment, with the goal of reducing the need for daily anesthesia through immersion in video.We designed an audiovisual-assisted therapeutic ambience in radiation therapy (AVATAR) system using a digital media player with wireless streaming and pico projector, and a radiolucent display screen positioned within the child's field of view to him or her with sufficient entertainment and distraction for the duration of serial treatments without the need for daily anesthesia. We piloted this system in 25 pediatric patients between the ages of 3 and 12 years. We calculated the number of fractions of radiation for which this system was used successfully and anesthesia avoided and compared it with the anesthesia rates reported in the literature for children of this age.Twenty-three of 25 patients (92%) were able to complete the prescribed course of radiation therapy without anesthesia using the AVATAR system, with a total of 441 fractions of treatment administered when using AVATAR. The median age of patients successfully treated with this approach was 6 years. Seven of the 23 patients were initially treated with daily anesthesia and were successfully transitioned to use of the AVATAR system. Patients and families reported an improved treatment experience with the use of the AVATAR system compared with anesthesia.The AVATAR system enables a high proportion of children to undergo radiation therapy without anesthesia compared with reported anesthesia rates, justifying continued development and clinical investigation of this technique.

Epidural Steroid Injections for Radiculopathy and/or Back Pain in Children and Adolescents: A Retrospective Cohort Study With a Prospective Follow-Up.
Regional anesthesia and pain medicine
2016; 41 (1): 86-92
Epidural steroid injections (ESIs) are commonly performed for adults with spinal pain and/or radiculopathy. Previous pediatric ESI case series were not identified by literature review. The primary aim of this study was to examine the safety and provisional outcomes of pediatric ESIs.With institutional review board approval, medical records were reviewed for patients aged 9 to 20 years receiving a first ESI at Boston Children's Hospital from 2003 through 2013. A subset of patients completed a Web-based follow-up questionnaire. Descriptive statistics included frequencies, medians, interquartile ranges, and Kaplan-Meier methods. Statistical comparisons were made using Wilcoxon rank sum, χ2, Fisher exact, and Cox proportional hazards regression analyses.A total of 224 patients aged 9 to 20 years underwent 428 ESIs. One hundred seventy-four (76.0%) patients had a lumbar disc herniation with radiculopathy; the others had a spectrum of other spinal disorders. There were no serious adverse events, hospitalizations, dural punctures, or nerve injuries. During follow-up, 69 (41.6%) of 166 previously nonoperated lumbar disc plus radiculopathy patients underwent discectomy at a median time of 128 days (interquartile range, 76-235 days) after first injection. Degrees of straight-leg raising at presentation was significantly associated with subsequent discectomy. On follow-up, patients who did and did not undergo discectomy had low pain scores and high function scores.Children and adolescents can receive ESIs under conscious sedation with good safety. Further prospective studies may better define the role for these injections in the comprehensive management of pediatric spinal pain disorders.

Extensive spinal epidural abscess treated with "apical laminectomies" and irrigation of the epidural space: report of 2 cases
JOURNAL OF NEUROSURGERY-SPINE
2015; 22 (3): 318-323
Spinal epidural abscess (SEA) is a rare but often devastating infection of the epidural space around the spinal cord. When an SEA is widespread, extensive decompression with laminectomy is often impossible, as it may subject the patient to very long operative times, extensive blood loss, and mechanical instability. A technique called "skip laminectomy" has been described in the literature, in which laminectomies are performed at the rostral and caudal ends of an abscess that spans 3-5 levels and a Fogarty catheter is used to mechanically drain the abscess, much like in an embolectomy. In this report of 2 patients, the authors present a modification of this technique, which they call "apical laminectomies" to allow for irrigation and drainage of an extensive SEA spanning the entire length of the vertebral column (C1-2 to L5-S1). Two patients presented with cervico-thoraco-lumbar SEA. Laminectomies were performed at the natural apices of the spine, namely, at the midcervical, midthoracic, and midlumbar spine levels. Next, a pediatric feeding tube was inserted in the epidural space from the thoracic laminectomies up toward the cervical laminectomy site and down toward the lumbar laminectomy site, and saline antibiotics were used to irrigate the SEA. Both patients underwent this procedure with no adverse effects. Their SEAs resolved both clinically and radiologically. Neither patient suffered from mechanical instability at 1 year after treatment. For patients who present with extensive SEAs, apical laminectomies seem to allow for surgical cure of the infectious burden and do not subject the patient to extended operating room time, an increased risk of blood loss, and the risk of mechanical instability.

A patient with surgically unrepaired single ventricle and uncontrolled amiodarone-induced thyrotoxicosis for emergent thyroidectomy.
A & A case reports
2014; 3 (5): 61-64
We present the case of a 20-year-old woman with a history of hypoplastic left heart syndrome, D-transposition of the great arteries, and mitral/pulmonary valve atresia without surgical palliation, who was admitted with persistent atrial flutter/fibrillation and worsening cardiac function from amiodarone-induced thyrotoxicosis. Despite maximal medical therapy, she continued to have uncontrolled thyrotoxicosis and underwent successful emergent thyroidectomy under general anesthesia. With advances in the treatment of congenital heart disease, more patients are surviving to adulthood and require emergent noncardiac surgery. Therefore, anesthesiologists must understand the principles for managing patients with congenital heart disease and how the patient's physiology may affect the anesthetic plan.

Minimally invasive spine surgery for adult degenerative lumbar scoliosis
2014; 36 (5)
Historically, adult degenerative lumbar scoliosis (DLS) has been treated with multilevel decompression and instrumented fusion to reduce neural compression and stabilize the spinal column. However, due to the profound morbidity associated with complex multilevel surgery, particularly in elderly patients and those with multiple medical comorbidities, minimally invasive surgical approaches have been proposed. The goal of this meta-analysis was to review the differences in patient selection for minimally invasive surgical versus open surgical procedures for adult DLS, and to compare the postoperative outcomes following minimally invasive surgery (MIS) and open surgery.In this meta-analysis the authors analyzed the complication rates and the clinical outcomes for patients with adult DLS undergoing complex decompressive procedures with fusion versus minimally invasive surgical approaches. Minimally invasive surgical approaches included decompressive laminectomy, microscopic decompression, lateral and extreme lateral interbody fusion (XLIF), and percutaneous pedicle screw placement for fusion. Mean patient age, complication rates, reoperation rates, Cobb angle, and measures of sagittal balance were investigated and compared between groups.Twelve studies were identified for comparison in the MIS group, with 8 studies describing the lateral interbody fusion or XLIF and 4 studies describing decompression without fusion. In the decompression MIS group, the mean preoperative Cobb angle was 16.7° and mean postoperative Cobb angle was 18°. In the XLIF group, mean pre- and postoperative Cobb angles were 22.3° and 9.2°, respectively. The difference in postoperative Cobb angle was statistically significant between groups on 1-way ANOVA (p = 0.014). Mean preoperative Cobb angle, mean patient age, and complication rate did not differ between the XLIF and decompression groups. Thirty-five studies were identified for inclusion in the open surgery group, with 18 studies describing patients with open fusion without osteotomy and 17 papers detailing outcomes after open fusion with osteotomy. Mean preoperative curve in the open fusion without osteotomy and with osteotomy groups was 41.3° and 32°, respectively. Mean reoperation rate was significantly higher in the osteotomy group (p = 0.008). On 1-way ANOVA comparing all groups, there was a statistically significant difference in mean age (p = 0.004) and mean preoperative curve (p = 0.002). There was no statistically significant difference in complication rates between groups (p = 0.28).The results of this study suggest that surgeons are offering patients open surgery or MIS depending on their age and the severity of their deformity. Greater sagittal and coronal correction was noted in the XLIF versus decompression only MIS groups. Larger Cobb angles, greater sagittal imbalance, and higher reoperation rates were found in studies reporting the use of open fusion with osteotomy. Although complication rates did not significantly differ between groups, these data are difficult to interpret given the heterogeneity in reporting complications between studies.

Breaking the glass ceiling: an interview with Dr. Shirley Graves, a pioneering woman in medicine
2014; 24 (4): 440-445
Shirley Graves M.D., D.Sc. (honorary) (1936), Professor Emeritus of Anesthesiology and Pediatrics at the University of Florida, was one of the most influential women in medicine in the 1960 and 1970s, a time when the medical profession was overwhelmingly male-dominated. In today's society, it is hard to believe that only 50 years ago, women were scarce in the field of medicine. Yet Dr. Graves was a pioneer in the fields of pediatric anesthesia and pediatric critical care medicine. She identifies her development of the pediatric intensive care unit and her leadership in the Division of Pediatric Anesthesia at the University of Florida as her defining contributions. Through her journal articles, book chapters, national and international lectures, and leadership in the American Society of Anesthesiology and the Florida Society of Anesthesiology, she inspired a generation of men and women physicians to conquer the unthinkable and break through the glass ceiling.

The development of a specialty: an interview with Dr. Mark C. Rogers, a pioneering pediatric intensivist.
Dr. Mark C. Rogers (1942-), Professor of Anesthesiology, Critical Care Medicine, and Pediatrics at the Johns Hopkins University, was recruited by the Department of Pediatrics at Johns Hopkins Hospital in 1977 to become the first director of its pediatric intensive care unit. After the dean of the medical school appointed him to chair the Department of Anesthesia in 1979, Rogers changed the course and culture of the department. He renamed it the Department of Anesthesiology and Critical Care Medicine, and developed a long-term strategy of excellence in clinical care, research, and education. However, throughout this period, he never lost his connection to pediatric intensive care. He has made numerous contributions to pediatric critical care medicine through research and his authoritative textbook, Rogers' Textbook of Pediatric Intensive Care. He established a training programme that has produced a plethora of leaders, helped develop the pediatric critical care board examination, and initiated the first World Congress of Pediatric Intensive Care. Based on a series of interviews with Dr. Rogers, this article reviews his influential career and the impact he made on developing pediatric critical care as a specialty.

Assessment of the length of myotomy in peroral endoscopic pyloromyotomy (G-POEM) using a submucosal tunnel technique (video).
Peroral endoscopic pyloromyotomy is a novel technique that has recently been described in the literature. There is little data to guide the length of myotomy created. The aim of study was to evaluate the proper incision length of the muscular layer during peroral endoscopic pyloromyotomy using a submucosal tunnel technique.The study was designed as a prospective ex vivo study. Fresh ex vivo porcine stomachs from animals weighing 80-100 kg and porcine stomachs from animals weighing 15-25 kg were used for pyloromyotomy. Four different myotomy lengths (1, 2, 3, and 4) were compared in the large animal series and three different myotomy lengths (1, 2, and 3) were compared in the small series. A total of 23 cases of the submucosal tunnel technique were performed by two endoscopists using 12 large stomachs and 11 small stomachs.The mean overall procedure time (±SD) of pyloromyotomy was 65.7 (±14.3) min. In the large stomach series, the mean pyloric diameter (±SD) and change from baseline (as percentage) following a 1, 2, 3, and 4 pyloromyotomy were 13.3 ± 9.5 mm (7.1 %), 20.7 ± 11.7 mm (10.6 %), 31.1 ± 15.0 mm (15.2 %), and 33.0 ± 15.0 mm (16.0 %), respectively. In the small stomach series, the changes of mean pyloric diameter following a 1, 2, and 3 cm pyloromyotomy were 12.2 ± 5.6 mm (7.5 %), 23.1 ± 7.6 mm (13.1 %), and 28.0 ± 10.4 mm (15.5 %), respectively.A 3 cm pyloromyotomy for a large animal series and 2 cm for the small animal series appeared to be most appropriate for enlargement of the pylorus.
