Employment Opportunities for Pediatric Critical Care Fellowship Trained Physicians in the United States.

Pediatric Critical Care Medicine (PCCM) training programs and trained fellows in the United State increased steadily without a corresponding increase in population growth. PCCM trainees worry about limited employment prospects. This study aimed to quantify the demand for PCCM trained physicians in the United States by prospectively tracking full-time employment opportunities over 12 months. The number of advertised opportunities identified was low compared with number of fellows likely to be seeking jobs during same time period. If market demand remains stable, there is risk of excess supply if number of newly fellowship-trained PCCM physicians continues to rise.

Fatal Cerebral Vasospasm following a Haemophilus influenzae Meningitis in a Young Child with Ventriculoperitoneal Shunt.

INTRODUCTION: Despite the successful implementation of Haemophilus influenzae vaccination, invasive serotypes still lead to a fatal infection. We recently cared for a patient with a ventriculoperitoneal shunt (VPS) and H. influenzae meningitis and septicemia complicated by vasospasm. Vasospasm caused by Haemophilus central nervous system infection has not been previously reported. CASE PRESENTATION: A 34-month-old patient with a recent VPS presented with H. influenzae meningitis and sepsis. Despite the explant of hardware, followed by maximum medical management, the patient developed stroke due to severe vasospasm, which led to diffused anoxic brain injury. CONCLUSIONS: We aim to alert for the possible critical condition caused by H. influenzae. It is essential to treat the underlying illness, despite the presence of a VPS. Surgical implant tends to be overlooked by other subspecialists. Being vaccinated to H. influenzae does not protect from different subtypes like non-typeable H. influenzae. The cause of vasospasm remains unclear.

Pediatric Deep Sedation for Ophthalmology Procedures in an Outpatient Setting, Risk Evaluation.

Background: Pediatric deep sedation (PDS) performed by a dedicated pediatric sedation service has been found to be safe, convenient, and efficient for minor procedures. Major complications such as cardiopulmonary resuscitation, intubation, and death are rare. However, minor complications such as desaturation, apnea, suctioning, or laryngospasm can occur infrequently. To date, little data exist evaluating PDS use for minor ophthalmology procedures. Aims: The aim of this study was to evaluate the incidence of complications for subjects receiving PDS for minor ophthalmology procedures. Setting: Pediatric children's hospital sedation service. Materials and Methods: This was a review of a prospectively collected database between 2018 and 2020. A hundred and thirty-four subjects aged 0-18 years, who underwent PDS for minor ophthalmology procedures, were compared to 1119 subjects who received PDS for other procedures (e.g., lumbar puncture, bone marrow aspirate/biopsy, and Botox). Statistical Analysis: SAS software, version 9.4, was used to determine variables associated with deep sedation that were predictive of complications. A multiple logistic regression procedure was conducted. Statistical significance was set at the 0.05 level. Results: Subjects receiving PDS for ophthalmology procedures had a higher rate of minor complications than the control group (n = 18, 13.4%, vs. n = 58, 5.7%; P < 0001). No major complications occurred in any of the studied subjects. The ophthalmology group had a higher rate of bag-mask ventilation, airway positioning, and suctioning. Conclusions: Ophthalmology procedures using PDS have a greater occurrence of minor complications compared to other painful procedures. No major complications were noted in either group, providing evidence that PDS can be performed safely for ophthalmology procedures using the sedation team model.

Interventricular Septal Pseudoaneurysm After Blunt Chest Trauma in a 6 Year Old: An Illustrative Case and Review.

Motor vehicle accident is the most common cause of blunt cardiac injury (BCI) in children (85.3%) due to the height of the child in relation to proper restraints and the compliant pediatric rib cage (J Trauma. 1996;40:200-202). Trauma to the chest wall may lead to injury of the myocardium, resulting in myocardial contusion, ventricular septal defect (VSD), ventricular free wall rupture, or valve compromise (J Trauma. 1996;40; 200-202; Heart Lung. 2012;41:200-202; J Inj Violence Res. 2012;4:98-100). There are several proposed mechanisms for the formation of VSD after blunt chest trauma including rupture of ischemic myocardium related to the initial trauma and reopening of a spontaneously closed congenital VSD. Also, chest trauma during isovolumetric contraction of the ventricles may generate enough intraventricular force to cause myocardial rupture (J Trauma. 1996;40:200-202; J Inj Violence Res. 2012;4:98-100; Korean J Pediatr. 2011;54:86-89; Ann Thorac Surg. 2012;94:1714-1716; J Emerg Trauma Shock. 2012;5:184-187). Previous case reports highlight the formation of a true VSD after BCI and the requirement of emergent repair (J Emerg Trauma Shock. 2012;5:184-187; Am Heart J. 1996;131:1039-1041; Korean Circ J. 2011;41:625-628; Ann Thorac Surg 2013;96:297-298; Kardiol Pol. 2013;71:992; Chin Med J. 2013;126:1592-1593). Reported is a case of a 6-year-old girl who developed an interventricular septal pseudoaneurysm after a motor vehicle accident of pedestrian versus car. On the day of presentation, she developed bradycardia after emergent surgical repair for abdominal trauma that required cardiopulmonary resuscitation including 5 minutes of chest compressions. At the time of resuscitation, an emergent transthoracic echocardiogram noted an interventricular pseudoaneurysm. She has been followed with serial transthoracic echocardiograms and has not required surgical intervention. We discuss the risk factors, prevalence, and diagnostic studies and recommended treatment options for structural heart disease after BCI.

Is Orally Administered Pentobarbital a Safe and Effective Alternative to Chloral Hydrate for Pediatric Procedural Sedation?

OBJECTIVES: Chloral hydrate had been extensively used for children undergoing sedation for imaging studies, but after the manufacturer discontinued production, pediatric sedation providers explored alternative sedation medications. Those medications needed to be at least as safe and as effective as chloral hydrate. In this study, we examined if pentobarbital is a suitable replacement for chloral hydrate. METHODS: Subjects who received pentobarbital were recruited from a prospectively collected database, whereas we used a retrospective chart review to study subjects who received chloral hydrate. Sedation success was defined as the ability to provide adequate sedation using a single medication. We included electively performed sedations for subjects aged 2 months to 3 years who received either pentobarbital or chloral hydrate orally. We excluded subjects stratified as American Academy of Anesthesiologists category III or higher and those who received sedation for electroencephalogram. The data collected captured subject demographics and complications. RESULTS: Five hundred thirty-four subjects were included in the final analysis, 368 in the chloral hydrate group and 166 in the pentobarbital group. Subjects who received pentobarbital had a statistically significant higher success rate [136 (82%) vs 238 (65%), p < 0.001], but longer sleeping time (18.1% vs 0%, p < 0.001) in all age groups. Subjects who received chloral hydrate had a higher risk of airway complications in the <1 year of age group (6.5% vs 1.8%, p = 0.03). CONCLUSIONS: For pediatric patients younger than 3 years of age undergoing sedation for imaging studies, oral pentobarbital may be at least as effective and as safe as chloral hydrate, making it an acceptable and practical alternative.

Gastric Volume and Its Relationship to Underlying Pathology or Acid-suppressing Medication.

BACKGROUND: Pulmonary aspiration during sedation is a major concern for sedation providers, making identifying high-risk patients a priority. Gastric fluid volume (GFV), an accepted risk factor for aspiration, has not been well characterized in fasting children. We hypothesized that GFV would increase with gastrointestinal (GI) pathology and decrease with regular acid-suppressor use. AIMS: The primary objective was to determine baseline GFV in fasting children. The secondary objectives were to evaluate the effect of GI pathology and regular use of acid-suppressing medications on GFV. SETTINGS AND STUDY DESIGN: This was prospective, observational study. MATERIALS AND METHODS: We endoscopically aspirated and measured GFV of 212 children fasting for >6 h who were sedated for esophagogastroduodenoscopy (EGD). Inclusion criteria were children up to 21 years of age, with the American Society of Anesthesiologists physical Status I and II presenting for elective EGD. After determining baseline GFV, the effect of GI pathology and effect of regular acid-suppressing medication use on GFV was analyzed. STATISTICAL ANALYSIS: Analysis of variance was used to compare the GFV among ages and pathology and medication groups. Student's t-test was used to compare GFV between genders and also to compare GFV in confounder analyses. RESULTS: For the studied 212 children, average GFV was 0.469 ± 0.448 mL/kg (0-2.663 mL/kg). We found no association between GI pathology and GFV (P = 0.147), or acid-suppressor use and GFV (P = 0.360). CONCLUSIONS: Average GFV in this study falls within the range of prior EGD-measured GFV in fasting children. Contrary to our hypothesis, we found no association between pathologies or regular acid-suppressor use on GFV. On the basis of GFV, children with GI disorders or those using acid-suppressors do not appear to pose an increased risk of aspiration. Future studies should discern differences in effects on GFV of immediate preprocedural versus the regular use of acid-suppressing medications.

Intranasal Dexmedetomidine as a Sedative for Pediatric Procedural Sedation.

OBJECTIVE: This study seeks to evaluate the efficacy and safety of intranasal (IN) dexmedetomidine as a sedative medication for non-invasive procedural sedation. METHODS: Subjects 6 months to 18 years of age undergoing non-invasive elective procedures were included. Dexmedetomidine (3 mcg/kg) was administered IN 40 minutes before the scheduled procedure time. The IN dexmedetomidine cohort was matched and compared to a cohort of 690 subjects who underwent sedation for similar procedures without the use of dexmedetomidine to evaluate for observed events/interventions and procedural times. RESULTS: One hundred (92%) of the 109 included subjects were successfully sedated with IN dexmedetomidine. There were no significant differences in the rate of observed events/interventions in comparison to the non-dexmedetomidine cohort. However, the IN dexmedetomidine group had a longer postprocedure sleep time when compared to the non-dexmedetomidine cohort (p < 0.001), which had a significant effect on recovery time (p = 0.024). Also, the dexmedetomidine cohort had longer procedure time and total admit time (p < 0.001 and p = 0.037, respectively). CONCLUSIONS: IN dexmedetomidine may be used for non-invasive pediatric procedural sedation. Subjects receiving IN dexmedetomidine had a similar rate of observed events/interventions as the subjects receiving non-dexmedetomidine sedation, with the exception of sleeping time. Also, patients sedated with IN dexmedetomidine had longer time to discharge, procedure time, and total admit time in comparison to other forms of sedation.

The risk of shorter fasting time for pediatric deep sedation.

BACKGROUND: Current guidelines adopted by the American Academy of Pediatrics calls for prolonged fasting times before performing pediatric procedural sedation and analgesia (PSA). PSA is increasingly provided to children outside of the operating theater by sedation trained pediatric providers and does not require airway manipulation. We investigated the safety of a shorter fasting time compared to a longer and guideline compliant fasting time. We tried to identify the association between fasting time and sedation-related complications. METHODS: This is a prospective observational study that included children 2 months to 18 years of age and had an American Society of Anesthesiologists physical status classification of I or II, who underwent deep sedation for elective procedures, performed by pediatric critical care providers. Procedures included radiologic imaging studies, electroencephalograms, auditory brainstem response, echocardiograms, Botox injections, and other minor surgical procedures. Subjects were divided into two groups depending on the length of their fasting time (4-6 h and >6 h). Complication rates were calculated and compared between the three groups. RESULTS: In the studied group of 2487 subjects, 1007 (40.5%) had fasting time of 4-6 h and the remaining 1480 (59.5%) subjects had fasted for >6 h. There were no statistically significant differences in any of the studied complications between the two groups. CONCLUSIONS: This study found no difference in complication rate in regard to the fasting time among our subjects cohort, which included only healthy children receiving elective procedures performed by sedation trained pediatric critical care providers. This suggests that using shorter fasting time may be safe for procedures performed outside of the operating theater that does not involve high-risk patients or airway manipulation.

Variability of DKA Management Among Pediatric Emergency Room and Critical Care Providers: A Call for More Evidence-Based and Cost-Effective Care?

Management protocols have been shown to be effective in the pediatric emergency medicine (PEM) and pediatric critical care (PCC) settings. Treatment protocols define clear goals which are achieved with consistency in implementation. Over the last decade, many new recommendations have been proposed on managing diabetic ketoacidosis (DKA). Although no perfect set of guidelines exist, many institutions are developing DKA treatment protocols. We sought to determine the variability between institutions in implementation of these protocols.

Clostridium sordellii as a Cause of Fatal Septic Shock in a Child with Hemolytic Uremic Syndrome.

Clostridium sordellii is a toxin producing ubiquitous gram-positive anaerobe, mainly associated with trauma, soft tissue skin infections, and gynecologic infection. We report a unique case of a new strain of Clostridium sordellii (not present in the Center for Disease Control (CDC) database) infection induced toxic shock syndrome in a previously healthy two-year-old male with colitis-related hemolytic uremic syndrome (HUS). The patient presented with dehydration, vomiting, and bloody diarrhea. He was transferred to the pediatric critical care unit (PICU) for initiation of peritoneal dialysis (PD). Due to increased edema and intolerance of PD, he was transitioned to hemodialysis through a femoral vascular catheter. He subsequently developed severe septic shock with persistent leukocytosis and hypotension, resulting in subsequent death. Stool culture confirmed Shiga toxin producing Escherichia coli 0157:H7. A blood culture was positively identified for Clostridium sordellii. Clostridium sordelli is rarely reported in children; to our knowledge this is the first case described in a pediatric patient with HUS.

Aminophylline infusion for status asthmaticus in the pediatric critical care unit setting is independently associated with increased length of stay and time for symptom improvement.

INTRODUCTION: The role of aminophylline in the treatment of severe acute asthma in the pediatric critical care unit (PCCU) is not clear. We sought to examine the association of aminophylline treatment with PCCU length of stay and time to symptom improvement. MATERIAL AND METHODS: Patients with severe acute asthma who were admitted to our PCCU and received aminophylline infusion were retrospectively compared with similar patients who did not receive aminophylline. The primary outcome measure was functional length of stay (i.e. time to which patients could be transferred to a general pediatric ward bed). A secondary outcome was time to symptom improvement. RESULTS: Adjusted functional length of stay was longer for subjects who received aminophylline (n = 49) than for the patients who did not (n = 47) (hazard ratio 0.396, p < 0.001), as well as the time for symptom improvement (hazard ratio 0.359, p < 0.001). In the group of subjects receiving aminophylline, those with a serum theophylline level ≥ 10 mcg/ml (therapeutic) (n = 31) had longer functional length of stay (hazard ratio 0.457, p = 0.0225) and time to symptom improvement (hazard ratio 0.403, p = 0.0085) than those with levels < 10 mcg/ml (sub-therapeutic) (n = 18). CONCLUSIONS: The addition of aminophylline to therapy with corticosteroids and inhaled ß-agonists was associated with statistically and clinically significant increases in functional length of stay and time to symptom improvement in the PCCU. This potential morbidity supports the National Asthma Education and Prevention Program guideline proscribing aminophylline use in acute asthma.

Extracorporeal membrane oxygenation as a platform for recovery: a case report of a child with pulmonary hemorrhage, refractory hypoxemic respiratory failure, and new onset goodpasture syndrome.

We report a case of a 9-year-old female with acute pulmonary hemorrhage and refractory hypoxemic respiratory failure secondary to Goodpasture syndrome (GS). After failing treatment with high frequency oscillatory ventilation and inhaled nitric oxide, she was successfully managed with venovenous extracorporeal membrane oxygenation (VV ECMO). The patient's weight at the time of cannulation was 31 kg. A 19 French 18 cm (arterial) Biomedicus cannula was inserted in the right internal jugular vein and used as the drain. A 17 French 50 cm (venous) Biomedicus cannula was inserted in the right femoral vein and used as the return. Then the patient was anticoagulated with 100 units/kg of intravenous heparin and the circuit was primed with one unit of packed red blood cells. VV ECMO was performed with an SIII Sorin roller head pump with integrated servo regulator and a Quadrox D Bioline coated oxygenator. Despite systemic anticoagulation with heparin, the patient's pulmonary hemorrhage resolved. Extracorporeal membrane oxygenation served as a platform through which we were able to provide renal replacement therapy and plasmapheresis. The patient was successfully discharged home with normal pulmonary function.
