Best Practices in Medical Documentation: A Curricular Module.

OBJECTIVE: To create and validate a checklist for high-quality documentation and pilot a multi-modal, immersive educational module across multiple institutions. We hypothesized that this module would improve knowledge, skills, and attitudes in medical documentation. METHODS: Module design was grounded in an established curriculum design framework. We conducted the study across 12 pediatric critical care fellowship programs between September 2017 and January 2018. Workshops were allotted 90 minutes for completion. We utilized a pre-/post- study design to determine the workshop's impact. Changes in knowledge were assessed through pre and post testing. Changes in skills were evaluated with a validated checklist for inclusion of key documentation elements. Changes in attitudes were determined through learner self-assessment RESULTS: 83 of 138 eligible fellows (60%) started the module and 62 of 83 (75%) completed data sets for analysis. Immediate post-testing demonstrated modest statistically significant improvement in knowledge, skills, and attitudes. The workshop was easily disseminated and deployed CONCLUSIONS: This study demonstrates that a multi-modal educational intervention can lead to improvement in medical documentation knowledge, skills, and attitudes in a cohort of PCCM fellows and be easily disseminated for use by other specialties and types of clinicians.

Life-Threatening Bleeding in Children: A Prospective Observational Study.

OBJECTIVES: The purpose of our study was to describe children with life-threatening bleeding. DESIGN: We conducted a prospective observational study of children with life-threatening bleeding events. SETTING: Twenty-four childrens hospitals in the United States, Canada, and Italy participated. SUBJECTS: Children 0-17 years old who received greater than 40 mL/kg total blood products over 6 hours or were transfused under massive transfusion protocol were included. INTERVENTIONS: Children were compared according bleeding etiology: trauma, operative, or medical. MEASUREMENTS AND MAIN RESULTS: Patient characteristics, therapies administered, and clinical outcomes were analyzed. Among 449 enrolled children, 55.0% were male, and the median age was 7.3 years. Bleeding etiology was 46.1% trauma, 34.1% operative, and 19.8% medical. Prior to the life-threatening bleeding event, most had age-adjusted hypotension (61.2%), and 25% were hypothermic. Children with medical bleeding had higher median Pediatric Risk of Mortality scores (18) compared with children with trauma (11) and operative bleeding (12). Median Glasgow Coma Scale scores were lower for children with trauma (3) compared with operative (14) or medical bleeding (10.5). Median time from bleeding onset to first transfusion was 8 minutes for RBCs, 34 minutes for plasma, and 42 minutes for platelets. Postevent acute respiratory distress syndrome (20.3%) and acute kidney injury (18.5%) were common. Twenty-eight-day mortality was 37.5% and higher among children with medical bleeding (65.2%) compared with trauma (36.1%) and operative (23.8%). There were 82 hemorrhage deaths; 65.8% occurred by 6 hours and 86.5% by 24 hours. CONCLUSIONS: Patient characteristics and outcomes among children with life-threatening bleeding varied by cause of bleeding. Mortality was high, and death from hemorrhage in this population occurred rapidly.

Establishing the Knowledge and Skills Necessary in Pediatric Critical Care Medicine: A Systematic Approach to Practice Analysis.

OBJECTIVES: To describe the practice analysis undertaken by a task force convened by the American Board of Pediatrics Pediatric Critical Care Medicine Sub-board to create a comprehensive document to guide learning and assessment within Pediatric Critical Care Medicine. DESIGN: An in-depth practice analysis with a mixed-methods design involving a descriptive review of practice, a modified Delphi process, and a survey. SETTING: Not applicable. SUBJECTS: Seventy-five Pediatric Critical Care Medicine program directors and 2,535 American Board of Pediatrics Pediatric Critical Care Medicine diplomates. INTERVENTIONS: A practice analysis document, which identifies the full breadth of knowledge and skill required for the practice of Pediatric Critical Care Medicine, was developed by a task force made up of seven pediatric intensivists and a psychometrician. The document was circulated to all 75 Pediatric Critical Care Medicine fellowship program directors for review and comment and their feedback informed modifications to the draft document. Concurrently, data from creation of the practice analysis draft document were also used to update the Pediatric Critical Care Medicine, was developed by a task force made up of seven pediatric intensivists and a psychometrician. The document was circulated to all 75 Pediatrics Pediatric Critical Care Medicine fellowship program directors for review and comment and their feedback informed modifications to the draft document. Concurrently, data from creation of the practice analysis draft document were also used to update the Pediatric Critical Care Medicine content outline, which was sent to all 2,535 American Board of Pediatrics Pediatric Critical Care Medicine diplomates for review during an open-comment period between January 2019 and February 2019, and diplomate feedback was used to make updates to both the content outline and the practice analysis document. MEASUREMENTS AND MAIN RESULTS: After review and comment by 25 Pediatric Critical Care Medicine program directors (33.3%) and 619 board-certified diplomates (24.4%), a comprehensive practice analysis document was created through a two-stage process. The final practice analysis includes 10 performance domains which parallel previously published Entrustable Professional Activities in Pediatric Critical Care Medicine. These performance domains are made up of between three and eight specific tasks, with each task including the critical knowledge and skills that are necessary for successful completion. The final practice analysis document was also used by the American Board of Pediatrics Pediatric Critical Care Medicine Sub-board to update the Pediatric Critical Care Medicine content outline. CONCLUSIONS: A systematic approach to practice analysis, with stakeholder engagement, is essential for an accurate definition of Pediatric Critical Care Medicine practice in its totality. This collaborative process resulted in a dynamic document useful in guiding curriculum development for training programs, maintenance of certification, and lifetime professional development to enable safe and efficient patient care.

Online Learning and Residents' Acquisition of Mechanical Ventilation Knowledge: Sequencing Matters.

OBJECTIVE: Rapid advancements in medicine and changing standards in medical education require new, efficient educational strategies. We investigated whether an online intervention could increase residents' knowledge and improve knowledge retention in mechanical ventilation when compared with a clinical rotation and whether the timing of intervention had an impact on overall knowledge gains. DESIGN: A prospective, interventional crossover study conducted from October 2015 to December 2017. SETTING: Multicenter study conducted in 33 PICUs across eight countries. SUBJECTS: Pediatric categorical residents rotating through the PICU for the first time. We allocated 483 residents into two arms based on rotation date to use an online intervention either before or after the clinical rotation. INTERVENTIONS: Residents completed an online virtual mechanical ventilation simulator either before or after a 1-month clinical rotation with a 2-month period between interventions. MEASUREMENTS AND MAIN RESULTS: Performance on case-based, multiple-choice question tests before and after each intervention was used to quantify knowledge gains and knowledge retention. Initial knowledge gains in residents who completed the online intervention (average knowledge gain, 6.9%; SD, 18.2) were noninferior compared with those who completed 1 month of a clinical rotation (average knowledge gain, 6.1%; SD, 18.9; difference, 0.8%; 95% CI, -5.05 to 6.47; p = 0.81). Knowledge retention was greater following completion of the online intervention when compared with the clinical rotation when controlling for time (difference, 7.6%; 95% CI, 0.7-14.5; p = 0.03). When the online intervention was sequenced before (average knowledge gain, 14.6%; SD, 15.4) rather than after (average knowledge gain, 7.0%; SD, 19.1) the clinical rotation, residents had superior overall knowledge acquisition (difference, 7.6%; 95% CI, 2.01-12.97;p = 0.008). CONCLUSIONS: Incorporating an interactive online educational intervention prior to a clinical rotation may offer a strategy to prime learners for the upcoming rotation, augmenting clinical learning in graduate medical education.

Assessing Competence in Central Venous Catheter Placement by Pediatric Critical Care Fellows: A National Survey Study.

OBJECTIVES: To describe the current approach to initial training, ongoing skill maintenance, and assessment of competence in central venous catheter placement by pediatric critical care medicine fellows, a subset of trainees in whom this skill is required. DESIGN: Cross-sectional internet-based survey with deliberate sampling. SETTING: United States pediatric critical care medicine fellowship programs. SUBJECTS: Pediatric critical care medicine program directors of Accreditation Council for Graduate Medical Education-accredited fellowship programs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A working group of the Education in Pediatric Intensive Care Investigators research collaborative conducted a national study to assess the degree of standardization of training and competence assessment of central venous catheter placement across pediatric critical care medicine fellowship programs. After piloting, the survey was sent to all program directors (n = 67) of Accreditation Council for Graduate Medical Education-accredited pediatric critical care medicine programs between July 2017 and September 2017. The response rate was 85% (57/67). Although 98% of programs provide formalized central venous catheter placement training for first-year fellows, only 42% of programs provide ongoing maintenance training as part of fellowship. Over half (55%) of programs use a global assessment tool and 33% use a checklist-based tool when evaluating fellow central venous catheter placement competence under direct supervision. Only two programs (4%) currently use an assessment tool previously published and validated by the Education in Pediatric Intensive Care group. A majority (82%) of responding program directors believe that a standardized approach to assessment of central venous catheter competency across programs is important. CONCLUSIONS: Despite national mandates for skill competence by many accrediting bodies, no standardized system currently exists across programs for assessing central venous catheter placement. Most pediatric critical care medicine programs use a global assessment and decisions around the ability of a fellow to place a central venous catheter under indirect supervision are largely based upon subjective assessment of performance. Further investigation is needed to determine if this finding is consistent in other specialties/subspecialties, if utilization of standardized assessment methods can improve program directors' abilities to ensure trainee competence in central venous catheter insertion in the setting of variable training approaches, and if these findings are consistent with other procedures across critical care medicine training programs, adult and pediatric.

Defining leadership competencies for pediatric critical care fellows: Results of a national needs assessment.

INTRODUCTION: Physicians in training, including those in Pediatric Critical Care Medicine, must develop clinical leadership skills in preparation to lead multidisciplinary teams during their careers. This study seeks to identify multidisciplinary perceptions of leadership skills important for Pediatric Critical Care Medicine fellows to attain prior to fellowship completion. METHODS: We performed a multi-institutional survey of Pediatric Critical Care Medicine attendings, fellows, and nurses. Subjects were asked to rate importance of 59 leadership skills, behaviors, and attitudes for Pediatric Critical Care practitioners and to identify whether these skills should be achieved before completing fellowship. Skills with the highest ratings by respondents were deemed essential. RESULTS: Five hundred and eighteen subjects completed the survey. Of 59 items, only one item ("displays honesty and integrity") was considered essential by all respondents. When analyzed by discipline, nurses identified 21 behaviors essential, fellows 3, and attendings 1 (p < 0.05). Nurses differed (p < 0.05) from attendings in their opinion of importance in 64% (38/59) of skills. CONCLUSIONS: Despite significant variability among Pediatric Critical Care attendings, fellows, and nurses in identifying which clinical leadership competencies are important for graduating Pediatric Critical Care fellows, they place the highest importance on skills in self-management and self-awareness. Leadership skills identified as most important may guide the development of interventions to improve trainee education and interprofessional care.

Developing a Tool to Assess Placement of Central Venous Catheters in Pediatrics Patients.

BACKGROUND: Pediatric critical care medicine requires the acquisition of procedural skills, but to date no criteria exist for assessing trainee competence in central venous catheter (CVC) insertion. OBJECTIVE: The goal of this study was to create and demonstrate validity evidence for a direct observation tool for assessing CVC insertion. METHODS: Ten experts used the modified Delphi technique to create a 15-item direct observation tool to assess 5 scripted and filmed simulated scenarios of CVC placement. The scenarios were hosted on a dedicated website from March to May 2013, and respondents recruited by e-mail completed the observation tool in real time while watching the scenarios. The goal was to obtain 50 respondents and a total of 250 scenario ratings. RESULTS: A total of 49 pediatrics intensive care faculty physicians (6.3% of 780 potential subjects) responded and generated 188 scenario observations. Of these, 150 (79.8%) were recorded from participants who scored 4 or more on the 5 scenarios. The tool correctly identified the expected reference standard in 96.8% of assessments with an interrater agreement kappa (standard error) = 0.94 (0.07) and receiver operating characteristic = 0.97 (95% CI 0.94-0.99). CONCLUSIONS: This direct observation assessment tool for central venous catheterization demonstrates excellent performance in identifying the reference standard with a high degree of interrater reliability. These assessments support a validity construct for a pediatric critical care medicine faculty member to assess a provider placing a CVC in a pediatrics patient.

Professionalism and Communication Education in Pediatric Critical Care Medicine: The Learner Perspective.

OBJECTIVE: Communication and professionalism are often challenging to teach, and the impact of the use of a given approach is not known. We undertook this investigation to establish pediatric critical care medicine (PCCM) trainee perception of education in professionalism and communication and to compare their responses from those obtained from PCCM fellowship program directors. METHODS: The Education in Pediatric Intensive Care (E.P.I.C.) Investigators used the modified Delphi technique to develop a survey examining teaching of professionalism and communication. After piloting, the survey was sent to all 283 PCCM fellows in training in the United States. RESULTS: Survey response rate was 47% (133 of 283). Despite high rates of teaching overall, deficiencies were noted in all areas of communication and professionalism assessed. The largest areas of deficiency included not being specifically taught how to communicate: as a member of a nonclinical group (reported in 24%), across a broad range of socioeconomic and cultural backgrounds (19%) or how to provide consultation outside of the intensive care unit (17%). Only 50% of fellows rated education in communication as "very good/excellent." However, most felt confident in their communication abilities. For professionalism, fellows reported not being taught accountability (12%), how to conduct a peer review (12%), and how to handle potential conflict between personal beliefs, circumstances, and professional values (10%). Fifty-seven percent of fellows felt that their professionalism education was "very good/excellent," but nearly all expressed confidence in these skills. Compared with program directors, fellows reported more deficiencies in both communication and professionalism. CONCLUSIONS: There are numerous components of communication and professionalism that PCCM fellows perceive as not being specifically taught. Despite these deficiencies, fellow confidence remains high. Substantial opportunities exist to improve teaching in these areas.

Are pediatric critical care medicine fellowships teaching and evaluating communication and professionalism?

OBJECTIVES: To describe the teaching and evaluation modalities used by pediatric critical care medicine training programs in the areas of professionalism and communication. DESIGN: Cross-sectional national survey. SETTING: Pediatric critical care medicine fellowship programs. SUBJECTS: Pediatric critical care medicine program directors. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Survey response rate was 67% of program directors in the United States, representing educators for 73% of current pediatric critical care medicine fellows. Respondents had a median of 4 years experience, with a median of seven fellows and 12 teaching faculty in their program. Faculty role modeling or direct observation with feedback were the most common modalities used to teach communication. However, six of the eight (75%) required elements of communication evaluated were not specifically taught by all programs. Faculty role modeling was the most commonly used technique to teach professionalism in 44% of the content areas evaluated, and didactics was the technique used in 44% of other professionalism content areas. Thirteen of the 16 required elements of professionalism (81%) were not taught by all programs. Evaluations by members of the healthcare team were used for assessment for both competencies. The use of a specific teaching technique was not related to program size, program director experience, or training in medical education. CONCLUSIONS: A wide range of techniques are currently used within pediatric critical care medicine to teach communication and professionalism, but there are a number of required elements that are not specifically taught by fellowship programs. These areas of deficiency represent opportunities for future investigation and improved education in the important competencies of communication and professionalism.

Decompensated septic shock in the setting of megace-induced severe adrenal suppression in an otherwise healthy pediatric patient: a case report.

A previously healthy 4-year-old boy presented to the emergency department at the Children's Hospital of Alabama with pneumonia caused by Pneumococcus infection and rapid progression to circulatory collapse. He was described as previously healthy except for being a "picky eater" and has been taking Megace (megestrol acetate) as an appetite stimulant for the past 2 years. We believe that the severity of his presentation was due in part to severe adrenal suppression from long-term Megace use. We were able to successfully resuscitate him with the addition of stress dose hydrocortisone, and he went on to have a complete recovery without any permanent disability. Previous literature has reported the adverse effect of Megace in suppressing adrenal function in patients with cancer and acquired immunodeficiency syndrome. This is the first report of this adverse effect in an otherwise healthy child. As the use of Megace becomes more widespread as an appetite stimulant in children, we hope to raise awareness of this important, potentially life-threatening adverse effect among physicians.

Pediatric off-label use of recombinant factor VIIa.

OBJECTIVE: Our goal was to report our institutional experience with recombinant factor VIIa for the treatment and/or prevention of bleeding in nonhemophiliac children. METHODS: This was a retrospective case series in a tertiary pediatric referral hospital. RESULTS: During 1999-2006, 135 patients received recombinant factor VIIa for off-label use. The median number of doses was 2; the median dose was 88 mug/kg. The most common diagnoses among patients receiving recombinant factor VIIa were disseminated intravascular coagulation/sepsis (28), surgical bleeding (19), procedural prophylaxis (16), and trauma (15). The median volume of blood products administered 24 hours before recombinant factor VIIa treatment was 29.7 vs 11.7 mL/kg 24 hours after treatment. Only 1 high-risk patient had significant bleeding after receiving prophylactic recombinant factor VIIa before an invasive procedure. Nonsurvivors had significantly increased incidence of multiple organ dysfunction syndrome (75%) compared with survivors (23%). The largest group of patients (n = 28) received recombinant factor VIIa for bleeding and/or coagulopathy because of disseminated intravascular coagulation; the mortality in this group was 26 (93%) of 28. Eleven patients received multiple doses of recombinant factor VIIa to treat bleeding complications after hematopoietic stem cell transplant, without improvement in blood use. Mortality in medical patients was 58% vs 16% in surgical patients. Three patients had significant thrombotic adverse events after receiving recombinant factor VIIa, resulting in 2 deaths and 1 leg amputation. CONCLUSIONS: Off-label use of recombinant factor VIIa significantly decreases blood-product administration; surgical patients had control of life-threatening bleeding with low associated mortality. Prophylactic recombinant factor VIIa may be effective in preventing bleeding if given before invasive procedures in children at high risk. Prolonged use of recombinant factor VIIa for bleeding complications after hematopoietic stem cell transplant is not effective in preventing packed red blood cell transfusion. Presence of disseminated intravascular coagulation and mulitorgan dysfunction syndrome may help predict futility of recombinant factor VIIa treatment. Off-label use of recombinant factor VIIa is associated with thromboembolic events in children.

Severe invasive community-associated methicillin-resistant Staphylococcus aureus infections in previously healthy children.

OBJECTIVE: An increase in community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections has been reported in the literature. Most severe, life-threatening infections were previously thought to be associated with chronically ill or frail patients. Our pediatric intensive care unit (PICU) has seen a recent dramatic increase in primary, severe invasive CA-MRSA infections in healthy children. DESIGN/SETTING: A retrospective chart review of all previously healthy patients admitted to our 19-bed combined medical-surgical PICU with a primary diagnosis of severe invasive, culture-proven CA-MRSA disease during the past 6 years. RESULTS: Eleven previously healthy patients were admitted to our PICU with severe, primary, invasive CA-MRSA infections from March 2006 through September 2007, in contrast to no patients meeting these criteria in the preceding 5 years. The mortality rate was 27%, compared with an overall PICU mortality rate during the study period of <7%. The mean PICU length of stay of these patients was 14.9 days, compared with an average PICU length of stay of 2.4 days. Despite initiation of treatment with vancomycin at admission to the PICU in all but one case, patients took a mean of 5.7 days to convert to negative blood cultures. Eight patients had bacteremia longer than 4 days. Six of the patients developed bilateral necrotizing pneumonia requiring prolonged mechanical ventilation. CONCLUSIONS: Severe CA-MRSA infections in healthy children are increasing at an alarming rate in our institution. This acute rise in incidence, coupled with an alarmingly high associated mortality rate, raises important questions about the initial empirical antibiotic therapy we use in caring for patients presenting with suspected life-threatening CA-MRSA disease. Vancomycin monotherapy may not be adequate treatment for severe CA-MRSA infections.

Matrix metalloproteinase activity in pediatric acute lung injury.

Pediatric Acute Lung Injury (ALI) is associated with a high mortality and morbidity, and dysregulation of matrix metalloproteinases (MMPs) may play an important role in the pathogenesis and evolution of ALI. Here we examined MMP expression and activity in pediatric ALI compared with controls. MMP-8, -9, and to a lesser extent, MMP-2, -3, -11 and -12 were identified at higher levels in lung secretions of pediatric ALI patients compared with controls. Tissue Inhibitor of Matrix metalloproteinase-1 (TIMP-1), a natural inhibitor of MMPs was detected in most ALI samples, but MMP-9:TIMP-1 ratios were high relative to controls. In subjects who remained intubated for >or=10 days, MMP-9 activity decreased, with > 80% found in the latent form. In contrast, almost all MMP-8 detected at later disease course was constitutively active. Discriminating MMP-9:TIMP-1 ratios were found in those who had a prolonged ALI course. These results identify a specific repertoire of MMP isoforms in the lung secretions of pediatric ALI patients, and demonstrate inverse changes in MMPs -8 and -9 with protracted disease.

Histamine 2 receptor antagonists vs intravenous proton pump inhibitors in a pediatric intensive care unit: a comparison of gastric pH.

PURPOSE: The aim of this study was to assess gastric pH in critically ill pediatric patients receiving intravenous stress ulcer medication. MATERIALS AND METHODS: A prospective study was done in 48 patients with a gastric tube in place who were receiving either ranitidine or a proton pump inhibitor and no enteral nutrition. Daily peak and trough gastric pHs were measured. RESULTS: The median age was 7 years 5 months (range, 1 month to 19 years), the median weight was 31 kg (range, 3-130 kg), and the median pediatric risk of mortality 2 (PRISM2) score was 12.5 (range, 0-31). All patients were intubated and 8 received dialysis. The average trough pH was 4.4 +/- 1.6 in the ranitidine group, 4.9 +/- 1.8 in the once daily proton pump inhibitor group, and 5.0 +/- 1.2 in the twice daily proton pump inhibitor group (P = .16). The average peak pH was 5.3 +/- 1.8 in the ranitidine group, 5.9 +/- 1.6 in the once daily proton pump inhibitor group, and 6.0 +/- 1.0 in the twice daily proton pump inhibitor group (P = .06). Three (10%) of 28 trough pH measurements in the twice daily proton pump inhibitor group were more acidic than 4 vs 24 (40%) of 60 in the ranitidine group, and 22 (40%) of 56 in the once daily proton pump inhibitor group (P = .02). One (4%) of 27 peak pH measurements in the twice daily proton pump inhibitor group were more acidic than 4 vs 13 (20%) of 61 in the ranitidine group, and 9 (16%) of 56 in the once daily proton pump inhibitor group (P = .12). Three patients (6%; 95% confidence interval, 0.51%-16%) developed upper gastrointestinal bleeding, and 4 patients (8%; 95% confidence interval, 0%-13%) developed ventilator-acquired pneumonia. CONCLUSIONS: Many critically ill pediatric patients receiving stress ulcer prophylaxis have a trough or peak gastric pH more acidic than 4.

Matrix metalloprotease-9 dysregulation in lower airway secretions of cystic fibrosis patients.

Matrix metalloproteases (MMPs) are proteolytic enzymes that regulate extracellular matrix turnover and aid in restoring tissue architecture following injury. There is an emerging role for extracellular matrix destruction in the pathogenesis of chronic neutrophilic lung diseases. In this study, we examined the expression and activity profiles of MMPs in lower airway secretions from cystic fibrosis (CF) patients, patients with acute respiratory failure (ARF), and normal controls. A discrete repertoire of MMP isoforms was found in the CF samples, with robust MMP-9 expression compared with normal controls and ARF. CF samples possessed increased levels of active MMP-9, as well as decreased amounts of tissue inhibitor of metalloprotease-1 (TIMP-1), a natural inhibitor of MMP-9. The CF inpatient samples demonstrated fully active MMP-9 activity compared with CF outpatients, ARF, and normal controls. CF samples also demonstrated increased human neutrophil elastase (HNE) levels compared with ARF and normal controls. To examine potential mechanisms for the protease dysregulation seen in the CF clinical samples, in vitro studies demonstrated that HNE could activate pro-MMP-9 and also degrade TIMP-1; this HNE-based activation, however, was not seen with MMP-8. A strong correlation was seen between HNE and MMP-9 activity in CF inpatient samples. Finally, the dysregulated MMP-9 activity seen in CF inpatient sputum samples could be significantly reduced by the use of MMP-9 inhibitors. Collectively, these findings further emphasize the proposed protease/antiprotease imbalance in chronic neutrophilic lung disease, providing a potential mechanism contributing to this proteolytic dysregulation.

Oral and nasal enteral tube placement errors and complications in a pediatric intensive care unit.

OBJECTIVE: To report five cases of errors in the placement of oral/nasal enteral tubes in a pediatric intensive care unit, and to review literature on placement techniques and complication rates. DESIGN: Case series and review of the literature. SETTING: A 19-bed pediatric intensive care unit in a tertiary care pediatric hospital. PATIENTS: A 14-yr-old male with respiratory distress following a near drowning, a 10-yr-old male with recurrent acute lymphocytic leukemia and Pneumocystis carinii pneumonia, a 16-yr-old female with complex congenital heart disease and respiratory failure, a 16-yr-old male with status asthmaticus, and a 2-yr-old male with congenital heart disease. INTERVENTIONS: None. MAIN RESULTS: Five cases of enteral tube placement errors occurred in our combined medical-surgical pediatric critical care unit within the past year. All five resulted in placement of the feeding tube in the respiratory tract, four occurred despite the presence of cuffed endotracheal tubes. Three of the five patients had subsequent worsening of their respiratory status. One developed a pneumothorax, one developed pulmonary hemorrhage, and one developed an increased oxygen requirement. CONCLUSIONS: Patients in the pediatric intensive care unit may have characteristics that place them at an increased risk for misplacement of oral or nasal enteral tubes into the respiratory tract. Placement of enteral tubes into the respiratory tract may cause serious morbidity and possibly mortality. Checking the placement of enteral tubes with traditional methods does not prevent misplacement in the respiratory tree, and new techniques should be considered.

Deep sedation with propofol in patients with Rett syndrome.

Herein we present the largest retrospective case-control series of deep sedation in patients with Rett syndrome, including discussion of the unique aspects of Rett syndrome that make these patients at high risk for sedation. Twenty-one patients with Rett syndrome and 21 control patients who received propofol for deep sedation to facilitate lumbar puncture were compared. Patients with Rett syndrome required significantly less propofol than control patients when standardized for weight and the duration of the procedure (P = .004). Seven of the 21 patients with Rett syndrome compared with none of the control patients experienced a serious adverse event, most of which were due to prolonged apnea (P = .004). All adverse events were transient, and all patients returned to their baseline after the procedure was completed. Sedation of patients with Rett syndrome is associated with a relatively high rate of complications and should not be done without appropriate personnel available who recognize the risks of sedating this unique population.

The use of enteral naloxone to treat opioid-induced constipation in a pediatric intensive care unit.

OBJECTIVE: To describe the effects of enteral naloxone used to treat opioid-induced constipation in pediatric intensive care patients. DESIGN: Retrospective chart review. SETTING: Pediatric intensive care unit. PATIENTS: Twenty-three patients who received opioid therapy and enteral naloxone in our institution from January 2003 to February 2004 were compared with a randomly sampled control group matched for age, weight, sex, and length of stay who received opioids but had not received enteral naloxone. INTERVENTIONS: None. MEASUREMENTS: Daily stool output, daily opiate usage, nutrition, adjuvant laxative use, and side effects were assessed. RESULTS: Patients stayed an average of 5 days (range, 0-13 days) in the pediatric intensive care unit before enteral administration of naloxone was instituted and received it for an average of 9 consecutive days (range, 3-30 days). Mean stool output for study patients before administration of enteral naloxone was 0.14 +/- 0.38 stools per day, whereas after its initiation it was 1.60 +/- 1.14 stools per day (p < .001). However, two patients developed significant opiate withdrawal symptoms after receiving enteral naloxone. The average stool output for control patients was 0.53 +/- 1.21 stools per day. CONCLUSIONS: Enteral naloxone may be effective in increasing stool output in opioid-induced constipation but carries the risk of introducing withdrawal symptoms. Further studies are needed to evaluate this agent for opioid-induced constipation in the intensive care unit.
