An observational study of gastric contents in pediatric patients with long bone fracture using gastric ultrasound.

BACKGROUND: The retention of gastric contents at surgery presentation is a risk factor for perioperative aspiration. A preoperative fasting (nil per os; NPO) interval is widely used to reduce this risk, but this approach is based on assumptions about the prevalence of typical gastric emptying rates. We assessed NPO guidelines' reliability with ultrasound (US) imaging and suction in pediatric patients presenting for single long-bone fracture repair after appropriate NPO intervals, when nearly all should have had empty stomachs. AIMS AND METHODS: This prospective cross-sectional observational study comprised 200 pediatric surgical patients. As their NPO times varied by food/drink type, we defined "weighted NPO units" as the lowest multiple of elapsed recommended NPO times between consumption and surgery for each type of food or drink. We used US to image the stomach and its contents before anesthesia induction, followed by gastric suction. We evaluated the relationships between weighted NPO units, US gastric contents grade, opioid analgesic dosage and timing, and suctioned volume. RESULTS: Despite meeting typical NPO standards (median 14 h fasting), many patients retained nontrivial quantities of gastric contents at surgery. Weighted NPO units did not exhibit statistically-significant relationships with either suctioned volume or US grade. However, suctioned volume did correspond well to US grade. CONCLUSION: NPO status may be a less reliable predictor of gastric contents at anesthesia induction in this patient population than has been assumed. Bedside US screening appears to provide more useful information for the planning of airway management.

Lumbar Erector Spinae Plane Block for Dega Pelvic Osteotomy in a Pediatric Patient With Complex Neurological Issues: A Case Report.

The erector spinae plane (ESP) block, initially designed for thoracic analgesia, has evolved into a versatile regional anesthesia technique with literature support for success in numerous contexts. In this case report, we highlight the successful application of ESP to provide postoperative analgesia for pediatric Dega osteotomy involving both the femoral head and acetabulum, in a patient with numerous neurological comorbidities that would have weighed against some more traditional regional anesthesia techniques. This case further highlights the versatility of ESP, demonstrating its use in blocking lumbar nerve roots in a pediatric patient with complex neurological challenges.

Trainee Perspectives Regarding the Effect of the Dobbs v. Jackson Women's Health Organization Supreme Court Decision on Obstetrics and Gynecology Training.

Objectives: We aimed to describe obstetrics and gynecology (OBGYN) trainees' anticipation of how the Dobbs v. Jackson Women's Health Organization (Dobbs) U.S. Supreme Court decision may affect their training. Methods: A REDCap survey of OBGYN residents and fellows in the United States from September 19, 2022, to December 1, 2022, queried trainees' anticipated achievement of relevant Accreditation Council for Graduate Medical Education (ACGME) training milestones, their concerns about the ability to provide care and concern about legal repercussions during training, and the importance of OBGYN competence in managing certain clinical situations for residency graduates. The primary outcome was an ACGME program trainee feeling uncertain or unable to obtain the highest level queried for a relevant ACGME milestone, including experiencing 20 abortion procedures in residency. Results: We received 469 eligible responses; the primary outcome was endorsed by 157 respondents (33.5%). After correction for confounders, significant predictors of the primary outcome were state environment (aOR = 3.94 for pending abortion restrictions; aOR = 2.71 for current abortion restrictions), trainee type (aOR = 0.21 for fellow vs. resident), and a present or past Ryan Training Program in residency (aOR = 0.55). Although the vast majority of trainees believed managing relevant clinical situations are key to OBGYN competence, 10%-30% of trainees believed they would have to stop providing the standard of care in clinical situations during training. Conclusions: This survey of OBGYN trainees indicates higher uncertainty about achieving ACGME milestones and procedural competency in clinical situations potentially affected by the Dobbs decision in states with legal restrictions on abortion.

The Association Between Well-Being and Empathy in Medical Residents: A Cross-Sectional Survey.

Objective: To evaluate the extent to which personal well-being may be associated with empathy, while controlling for potential confounders. Settings/Location: Residency programs throughout the United States. Subjects: A total of 407 medical residents from residencies including general medicine, surgery, specialized and diagnostic medicine participated in this study. Outcome Measures: Well-being was measured using the modified existential well-being subscale of the spiritual well-being scale. Empathy was measured using the Jefferson Scale of Empathy. Results: Well-being was found to be positively correlated with empathy when adjusted for possible confounders (p < 0.001). In addition to well-being, other factors noted to be statistically significant contributors to higher empathy scores while controlling for the others included age, gender, year in residency, specialty, and work-hours (p < 0.05 for each). After controlling for these factors, a resident's year in residency was not found to be a statistically significant contributor to empathy score. Conclusions: In this study, well-being was associated with empathy in medical and surgical residents. Empathy is a fundamental component of physician competency, and its development is an essential aspect of medical training. These findings suggest that efforts to increase well-being may promote empathy among medical residents.

Use of Transparent Film Dressing to Facilitate Mask Ventilation in Bearded Patients.

BACKGROUND: Mask ventilation is a critical airway procedure made more difficult in the bearded patient. OBJECTIVE: We sought to objectively investigate whether application of transparent cling film (TegadermTM; 3M Healthcare, Maplewood, MN) over a beard in the operating room improves the quality of mask ventilation. METHODS: This was a randomized crossover trial of bearded adult patients undergoing surgery. Exclusions included emergency procedures, American Society of Anesthesiologists physical status classification > 3, a documented history of difficult mask ventilation, and body mass index (BMI) > 50. Transparent cling film was applied snuggly over the lower face with a 2- to 3-cm slit cut over the mouth after anesthesia induction. Mask ventilation performed by an anesthesiology resident, anesthesiology assistant, or anesthesiology assistant student and standardized to a thenar-eminence grip without use of airway adjuncts in a sniffing position. Standardized pressure-controlled ventilations were delivered via an anesthesia machine. A calibrated external pneumotachograph was used to measure delivered and returned tidal volumes from which raw and percent air leak were calculated. A clinically significant difference was determined a priori to be 15%, necessitating the enrollment of 25 patients. RESULTS: Of 25 subjects, 96% were men with a mean ± SD BMI of 29.3 ± 6. Seventeen (68%) had a full beard and 8 (32%) had a partial beard. The mean ± SD leakage was 48% ± 26% for transparent cling film vs. 46% ± 20% without its application, which was not significantly different (p = 0.67). CONCLUSIONS: The use of transparent cling film to cover the lower half of the bearded face did not have an impact on the ability or efficacy to perform mask ventilation in the operating room setting. CLINICALTRIALS: gov, Number NCT04274686.

Randomized Trial on Expectations and Pain Control Advancement in Surgery: The REPAIR Study.

IMPORTANCE: Following standardized preoperative education and adoption of shared decision making positively affects postoperative narcotic practices. OBJECTIVES: The aim of this study was to assess the impact of patient-centered preoperative education and shared decision making on the quantities of postoperative narcotics prescribed and consumed after urogynecologic surgery. STUDY DESIGN: Women undergoing urogynecologic surgery were randomized to "standard" (standard preoperative education, standard narcotic quantities at discharge) or "patient-centered" (patient-informed preoperative education, choice of narcotic quantities at discharge) groups. At discharge, the "standard" group received 30 (major surgery) or 12 (minor surgery) pills of 5-mg oxycodone. The "patient-centered" group chose 0 to 30 (major surgery) or 0 to 12 (minor surgery) pills. Outcomes included postoperative narcotics consumed and unused. Other outcomes included patient satisfaction/preparedness, return to activity, and pain interference. An intention-to-treat analysis was performed. RESULTS: The study enrolled 174 women; 154 were randomized and completed the major outcomes of interest (78 in the standard group, 76 in the patient-centered group). Narcotic consumption did not differ between groups (standard group: median of 3.5 pills, interquartile range [IQR] of [0, 8.25]; patient centered: median of 2, IQR of [0, 9.75]; P = 0.627). The patient-centered group had fewer narcotics prescribed ( P < 0.001) and unused ( P < 0.001), and chose a median of 20 pills (IQR [10, 30]) after a major surgical procedure and 12 pills (IQR [6, 12]) after a minor surgical procedure, with fewer unused narcotics (median difference, 9 pills; 95% confidence interval, 5-13; P < 0.001). There were no differences between groups' return to function, pain interference, and preparedness or satisfaction ( P > 0.05). CONCLUSIONS: Patient-centered education did not decrease narcotic consumption. Shared decision making did decrease prescribed and unused narcotics. Shared decision making in narcotic prescribing is feasible and may improve postoperative prescribing practices.

The Variation of Chargemaster Price Listings for Urogynecologic Procedures.

IMPORTANCE: A 2018 Executive Order calling for price transparency required hospitals to publicly provide chargemasters, which are detailed lists of standard price listings for billable medical procedures. OBJECTIVES: The objective of this study was to evaluate price listing variations in common urogynecology procedures. STUDY DESIGN: This was a cross-sectional study of chargemasters obtained between February and April 2020 from hospitals across 5 states chosen to reflect the diversity of health systems in the United States. Hospital characteristic and quality metric data were obtained from the Homeland Infrastructure Foundation, U.S. Department of Agriculture, and U.S. Centers for Medicare & Medicaid Services websites. Current Procedural Terminology codes and procedure names for 9 urogynecologic procedures were used to search each chargemaster and extract price listings. Price listings were compared with data on quality, population demographics, and hospital characteristics to determine if any significant relationships existed. RESULTS: Eight hundred thirty-four chargemasters were identified. Price listings for most procedures differed significantly across the 5 states, including colpocleisis, cystoscopy with chemodenervation, diagnostic cystoscopy, diverticulectomy, sacral neuromodulation, midurethral sling, and sacrospinous ligament fixation. Price listings were significantly higher in urban hospitals than rural hospitals for 6 procedures. No significant association was seen with price listing and quality measures for most procedures. CONCLUSIONS: Listed prices varied for several urogynecologic procedures. Some of this variation is associated with hospital characteristics such as urban setting. However, notably, price listing was not associated with quality. Further investigation of chargemaster price listings with hospital characteristics and quality metrics and with what is actually paid by patients is imperative for patients to navigate charges.

Electrophysiological Analyses of Human Dorsal Root Ganglia and Human Induced Pluripotent Stem Cell-derived Sensory Neurons From Male and Female Donors.

Human induced pluripotent stem cell-derived sensory neurons (hiPSC-SNs) and human dorsal root ganglia neurons (hDRG-N) are popular tools in the field of pain research; however, few groups make use of both approaches. For screening and analgesic validation purposes, important characterizations can be determined of the similarities and differences between hDRG-N and hiPSC-SNs. This study focuses specifically on the electrophysiology properties of hDRG-N in comparison to hiPSC-SNs. We also compared hDRG-N and hiPSC-SNs from both male and female donors to evaluate potential sex differences. We recorded neuronal size, rheobase, resting membrane potential, input resistance, and action potential waveform properties from 83 hiPSCs-SNs (2 donors) and 108 hDRG-N neurons (8 donors). We observed several statistically significant electrophysiological differences between hDRG-N and hiPSC-SNs, such as size, rheobase, input resistance, and several action potential waveform properties. Correlation analysis also revealed many properties that were positively or negatively correlated, some of which were differentially correlated between hDRG-N and hiPSC-SNs. This study shows several differences between hDRG-N and hiPSC-SNs and allows a better understanding of the advantages and disadvantages of both for use in pain research. We hope this study will be a valuable resource for pain researchers considering the use of these human in vitro systems for mechanistic studies and/or drug development projects. PERSPECTIVE: hiPSC-SNs and hDRG-N are popular tools in the field of pain research. This study allows for a better functional understanding of the pros and cons of both tools.

Midazolam for Anesthetic Premedication in Children: Considerations and Alternatives.

Premedication in anesthesia has long been used to reduce patient anxiety, increase patient compliance, and supplement the overall anesthetic. In pediatric populations, premedication also has the indirect benefits of reducing parental anxiety as well as both the incidence and severity of emergence delirium. Oral midazolam, selected for its ease of administration, short duration of action, and reliable anxiolytic and amnestic effects, has been a favorite choice in this role for decades. The side effect profile of midazolam is also relatively benign, heavily dose-dependent, and easily managed in the perioperative setting. While midazolam appears to be an ideal adjunct in the anesthetic care of pediatric patients, there is a growing body of evidence suggesting prolonged benzodiazepine exposure causes neurodevelopmental changes in infants. This evidence, along with the 2017 Food and Drug Administration (FDA) warning labels for the use of select anesthetic medications, including midazolam in children under the age of three, has led to some debate in the anesthetic community over the continued use of this anesthetic for premedication in pediatric populations. This article aims to educate the reader on the history of midazolam as a premedication agent in pediatric populations and examine the evidence supporting and against its continued use in this role.

Electrophysiological analyses of human dorsal root ganglia and human induced pluripotent stem cell-derived sensory neurons from male and female donors.

Human induced pluripotent stem cell-derived sensory neurons (hiPSC-SNs) and human dorsal root ganglia (hDRG) neurons are popular tools in the field of pain research; however, few groups make use of both approaches. For screening and analgesic validation purposes, important characterizations can be determined of the similarities and differences between hDRG and hiPSC-SNs. This study focuses specifically on electrophysiology properties of hDRG in comparison to hiPSC-SNs. We also compared hDRG and hiPSC-SNs from both male and female donors to evaluate potential sex differences. We recorded neuronal size, rheobase, resting membrane potential, input resistance, and action potential waveform properties from 83 hiPSCs-SNs (2 donors) and 108 hDRG neurons (9 donors). We observed several statistically significant electrophysiological differences between hDRG and hiPSC-SNs, such as size, rheobase, input resistance, and several actional potential (AP) waveform properties. Correlation analysis also revealed many properties that were positively or negatively correlated, some of which were differentially correlated between hDRG and hiPSC-SNs. This study shows several differences between hDRG and hiPSC-SNs and allows better understanding of the advantages and disadvantages of both for use in pain research. We hope this study will be a valuable resource for pain researchers considering the use of these human in vitro systems for mechanistic studies and/or drug development projects.

Management of a Large Post-tonsillectomy Thrombus Obstructing the Laryngeal View: A Case Report.

Anesthetic management of children with a post-tonsillectomy hemorrhage can be challenging. The patients may be anemic and hypovolemic and are at increased risk of having a difficult airway due to active bleeding, vomiting, and anatomical issues. A clot may also interfere with viewing the larynx, further exacerbating the difficulty of intubation. We describe a pediatric post-tonsillectomy hemorrhage case complicated by a large obstructing clot that was removed with Magill forceps after the airway was successfully secured with an endotracheal tube during rapid sequence induction.

Propofol-Related Infusion Syndrome in a Child With Refractory Status Epilepticus: Successful Resuscitation With Veno-Arterial Extracorporeal Membrane Oxygenation, Continuous Renal Replacement Therapy, and Therapeutic Plasma Exchange.

Propofol is used for sedation, anxiolysis, anesthesia induction, and as an anticonvulsant. In cases of refractory status epilepticus (RSE), propofol is more efficient than barbiturates. We present a case of a 3-year-old female with RSE who developed propofol-related infusion syndrome (PRIS) despite low dosage after failed attempts with multiple anti-epileptic drips and bolus therapies. Careful consideration must be made before initiating propofol administration for RSE. We discuss our PRIS treatment approach with extracorporeal membrane oxygenation, therapeutic plasma exchange, and continuous renal replacement therapy leading to our patient recovering to baseline and being discharged home from the hospital.

Rapid Evaluation of Gastric Content With Ultrasound: An Educational Tool.

Pulmonary aspiration is a severe complication in patients receiving anesthesia for surgical procedures. The risk and severity of aspiration are significantly higher in the presence of substantial gastric contents. Bedside ultrasound imaging of the gastric antrum is emerging as a rapid and valuable method to evaluate gastric contents before surgery. Rapid gastric ultrasound using a three-category grading system promotes timely decision-making to help in emergent or urgent surgeries by identifying patients with potentially high gastric volumes or solid food contents. In emergent cases with limited time, a single ultrasound view of the gastric antrum is still likely to yield helpful information. In this report, we argue that bedside ultrasound offers a more reliable assessment of gastric contents than assumptions based on time-based fasting guidelines.

Utilizing Cohesive Bandage to Prevent Adverse Effects of Bleomycin Sclerotherapy: A Case Report.

Sclerotherapy with bleomycin can cause cosmetic complications, including flagellate dermatitis and hyperpigmentation, induced or exacerbated by microtrauma to the skin. We report a case of a 9-year-old pediatric patient with congenital vascular malformations in which a cohesive bandage (eg, 3M Coban) was utilized to prevent bleomycin-induced hyperpigmentation. Postoperatively and on follow-up, there were no signs of hyperpigmentation or dermatitis in our patient. This report highlights using skin protective measures during bleomycin sclerotherapy for improved postoperative outcomes. If a patient is undergoing bleomycin sclerotherapy, consider removing adhesive where possible and using cohesive bandage to secure lines, airway instruments, and monitoring equipment.

Medication Abortion Follow-Up Rates in a Rural Population Before and After Introduction of a Remote Follow-Up Option.

Background: Medication abortion (MAB) follow-up historically involves visiting a health care facility for ultrasonography or laboratory testing. In rural states such as New Mexico, many patients travel hours for MAB, making two visits burdensome. Studies demonstrate feasibility, safety, and patient preference for remote follow-up. Materials and Methods: We evaluated whether MAB follow-up by telephone had noninferior loss-to-follow-up (LTFU) rates compared with ultrasonography or laboratory follow-up in a rural population. This was a retrospective chart review of University of New Mexico MAB LTFU rates after changing to telephone follow-up (home group, n = 136). Patients were propensity-matched in a 1:2 ratio to a historical cohort (health care group, n = 272) to eliminate significant differences. We defined LTFU as no contact within 50 days. We evaluated complications requiring intervention, possible ongoing pregnancy, completion of the home follow-up protocol (7- and 30-day calls, high-sensitivity urine pregnancy test [UPT]), follow-up by intended method (home or health care), and number of call attempts. Results: LTFU rates for the home group (n = 23, 17%) were noninferior to the health care group (n = 60, 22%, p = 0.24). Rates of complications requiring intervention (p = 0.83) and possible ongoing pregnancy (p = 0.72) among the home group were similar to the health care group. Ninety-seven (71%) home group patients completed the initial call, 79 (58%) completed the UPT, and 86 (69%) completed the 30-day call. Ninety-five (70%) home group patients followed up by intended method, comparable with the health care group (n = 199, 73%, p = 0.56). Staff made a median of 3 (interquartile range: 2-4) calls per home group patient. Conclusions: Remote MAB LTFU rates were noninferior to in-person LTFU rates.

Anesthetic Management of a Patient With Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-Like Episodes Syndrome During Extensive Spinal Surgery With Both Motor Evoked Potentials and Somatosensory Evoked Potentials: A Case Report.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a complex and infrequently encountered mitochondrial cytopathy. Patients with MELAS often present with multi-systemic manifestations, making their anesthetic management particularly challenging. In this case report, we describe in detail our anesthetic approach for a 19-year-old male with confirmed MELAS linked to an m.3243A>G mutation. The patient had been diagnosed with MELAS at age 12 following a stroke-like episode and presented with progressive spinal deformities. He exhibited a 70° thoracic spine curvature and an 80° kyphosis, requiring a T1-L2 posterior spinal fusion. The surgical plan included neuromonitoring with both somatosensory and motor evoked potentials. Intravenous anesthetics such as propofol are typically preferred in this context due to their reduced interference with neuromonitoring compared to volatile anesthetics. Anticipating a surgical duration of six to seven hours, however, we hesitated to rely on propofol for this extended period due to its potential risks of lactic acidosis in the context of MELAS. Given that propofol infusion for extended periods (>48 hours) or at high doses (≥5 mg·kg-1·hour-1) is known to induce propofol-related infusion syndrome, and coupled with our concerns about the risk of lactic acidosis in this patient, we were compelled to design an anesthetic plan that avoided propofol altogether without excessive use of volatile anesthetics. This proactive approach ensured the maintenance of consistent neuromonitoring signals and the patient's safety, especially given his underlying mitochondrial dysfunction. Our primary rationale in presenting this case report is to highlight the challenges posed by MELAS in the setting of extended surgery, with a focus on anesthetic considerations during neuromonitoring. For prolonged surgeries that typically rely heavily on intravenous anesthetics, which interfere less with neuromonitoring than volatile anesthetics, the use of propofol should be approached with caution in MELAS contexts due to its associated risk of lactic acidosis. To our knowledge, this is the first case report that described the anesthetic management of a patient with MELAS undergoing a procedure of such duration, requiring both somatosensory and motor evoked potential neuromonitoring. We believe our experiences will serve as a reference for anesthesiologists and perioperative teams faced with similar challenging clinical situations.

Successful Rescue Ventilation of an Infant With a Laryngeal Mask Airway After Accidental Extubation in the Prone Position During Open Calvarial Reconstruction of a Craniosynostosis: A Case Report.

In this case report, we present a critical situation during an open calvarial reconstruction involving an 11-month-old infant. The patient experienced accidental extubation, requiring immediate intervention while in the prone position. Approximately two hours post-incision, ventilation became increasingly difficult due to a significant leak detected in the system. On closer inspection, it was observed that both the rubber tourniquet responsible for securing the anesthesia circuit and the tape that held the endotracheal tube in place had become loosened. In response to this emergency, the decision was made to remove the displaced endotracheal tube. We successfully introduced a 1.5 laryngeal mask airway (LMA; Unique™, Teleflex Incorporated, Wayne, PA), which restored ventilation. The patient maintained stable oxygen levels throughout this emergency period, displaying no signs of desaturation. An hour post-intervention, the surgical procedure was completed. The process of removing the LMA was uneventful without any complications. In the setting of emergent airway management, especially for patients in the prone position during surgical procedures, accidental extubation presents a challenge for healthcare providers. This case highlights the importance of prompt decision-making and having alternative airway devices on hand, such as an LMA.

Chargemaster Pricing Variation for Commonly Billed Procedures in Interventional Cardiology.

OBJECTIVES: A chargemaster is a database of all of the billable items offered by a hospital with their base price listings. A 2018 executive order required all American hospitals to publish their chargemasters to increase price transparency and reduce healthcare expenditures. Chargemaster listings, however, demonstrate marked variability and inconsistency and have not been associated with consumer benefit. The objective of this study was to analyze chargemasters for commonly billed interventional cardiology procedures across five diverse states to explore relationships between price listings and hospital characteristics, ownership, location, and hospital quality. METHODS: Chargemasters were downloaded from hospitals in five states selected to represent the nation's healthcare diversity. Price listings for five interventional cardiology procedures (percutaneous coronary angiography, coronary angiography, single-vessel angioplasty, single-vessel stent, and percutaneous coronary intervention of acute myocardial infarction) were extracted. Statistical analyses such as the Kruskal-Wallis test were performed to explore relationships between mean chargemaster price listings for each procedure and hospital characteristics, ownership, location, and quality ratings. RESULTS: The median mean chargemaster price of four of the five interventional cardiology procedures significantly differed across all states. Price listings were significantly higher in urban versus rural areas and in general acute care hospitals and state government-owned facilities. The highest prices were found with the highest hospital quality rating. CONCLUSIONS: Chargemaster price listings for common interventional cardiology procedures varied significantly across these five states. Urban and metropolitan hospital location, hospital type, and hospital ownership could be factors driving increased chargemaster procedure prices. Prices were highest at hospitals with the highest quality rating.

Incidence of acute compartment syndrome with routine use of regional anesthesia for patients with long bone fractures: a large single-center retrospective review from a level I trauma tertiary academic institution.

INTRODUCTION: Traditionally, using peripheral nerve blocks (PNBs) in patients with long bone fractures has been limited due to concerns that it may interfere with the timely diagnosis of acute compartment syndrome (ACS). However, our large academic institution and level I trauma center have been using regional anesthesia routinely for pain management of patients with long bone fractures for more than a decade, with strict adherence to a comprehensive management protocol. The aim of this retrospective review is to present our experience with this practice. METHODS: Following Institutional Review Board approval, we performed a retrospective chart review of patients with long bone fractures and ACS over a 10-year period (2008-2018). RESULTS: 26 537 patients were included in the review. Approximately 20% of these patients required surgery, and 91.5% of surgically treated patients received regional anesthesia. The incidence of ACS in our cohort was 0.1% or 1.017 per 1000 patients with long bone fractures. CONCLUSION: Current recommendations on using PNBs in patients at risk for ACS have been mainly based on expert opinion and dated case reports. Due to the nature of the condition, prospective data are lacking. Our large observational dataset evaluated the risk of missing or delaying ACS diagnosis when PNBs were offered for trauma patients and demonstrated a relatively low incidence of ACS despite the routine use of PNBs under strictly protocolized conditions when patients were managed by a dedicated multidisciplinary care team.

Successful Administration of Preoperative Botox for Giant Omphalocele Repair With Ultrasound Guidance.

We present a case of a four-year-old male with a history of giant omphalocele who underwent ultrasound-guided Botox injection to bilateral anterior abdominal wall musculature in preparation for definitive repair. Botox administration was successfully combined with preoperative subfascial tissue expanders to achieve definitive midline closure of the anterior abdominal wall defect. Our experience suggests that Botox can be safely used as part of the treatment plan for giant omphalocele repair.
