Desaturation in procedural sedation for children with long bone fractures: Does weight status matter?

Association of Pre-procedural Anxiety with Procedure-related Pain During Outpatient Pediatric Burn Care: A Pilot Study

The relationship between preprocedural anxiety and pain is not clear but has the potential to change the way pediatric patients need to be cared for prior to burn procedures. Using results from our recent randomized clinical trial among outpatient burn patients (n=90) age 6-17 years, the objective of this subsequent analysis was to assess whether preprocedural anxiety was associated with self-reported and researcher observed pain scores. Anxiety before the dressing change was assessed using an abbreviated State-Trait Anxiety Inventory for Children (range 6-21) and reported with 95% confidence intervals (CI). Self-reported pain was reported using a Visual Analog Scale (range 0-100) and observed pain was assessed using the Face, Legs, Activity, Cry, and Consolability-revised scale. Over half of patients (58.9%) reported mild anxiety (score <12) and about 5% of patients reported severe anxiety (score >16). Younger children (6-8 years) reported higher anxiety scores than older children (15-17 years), but the difference did not achieve statistical significance (mean=12.7, 95% CI: 11.5-13.9, p=0.09). Nonparametric spearman correlation indicated that anxiety score was significantly correlated with observed pain (p=0.01) and self-reported overall pain neared statistical significance (p=0.06). In the final logistic regression of reporting moderate-to-severe pain (pain score >30), the association between anxiety scores and self-reported overall moderate-to-severe pain was statistically significant (p=0.03) when adjusting for race, healing degree, and pain medication use within 6 hours prior to burn dressing care. This pilot study provides preliminary data showing that anxiety before outpatient pediatric burn dressing changes is significantly associated with self-reported overall moderate-to-severe pain.

A Perspective on Management of Limb Fractures in Obese Children: Is It Time for Dedicated Guidelines?

Limb fractures are the most common injuries in pediatric orthopedics. Early and late complications are often not preventable, even when providing the best treatment; furthermore, these injuries are largely implicated in medico-legal claims. The development of evidence-based guidelines is one of the main goals of medical research. Approved guidelines for diagnosis, treatment, and follow up are fundamental to obtain the best results in medical practice. Guidelines in pediatric traumatology have been developed, even though specific conditions, like obesity, could influence their drafting. The cast and fixation systems usually applied in pediatric fractures provide a growth plate sparing, a satisfying reduction, and good stress resistance, mostly because of a lower bodyweight compared to adults. Several studies suggest that obesity influences the bone quality, the management, and the outcomes in cases of fracture. High body weight increases the risk of trauma, modifies fracture characteristics, and increases the risk of incomplete reduction. Fractures in obese children have a higher rate of complications, regardless of conservative or surgical treatment. In obese children, surgical treatment is often used more frequently than with non-obese children. Such considerations are valid both for lower and upper limb fractures. The aim of this paper is to discuss recent scientific literature and provide a perspective on the benefits of a dedicated approach in the management of obese children. Guideline updates could improve healthcare quality in a pediatric setting, and also reduce medico-legal implications.

The Role of Obesity in Pediatric Orthopedics

Pediatric obesity has become a worldwide epidemic and leads to notable effects on the developing skeleton that can have lifelong implications. Obesity in the pediatric population alters bone metabolism, increasing the risk for fracture. It can alter the presentation of common pediatric orthopaedic conditions such as scoliosis. Obesity also leads to changes in the patterns and severity of pediatric fractures as well as alters conservative fracture treatment due to increased displacement risk. Obese pediatric trauma patients place a high burden on the nationwide hospital system in a variety of ways including the increased risk of perioperative complications. Obesity is modifiable, and addressing the issue can improve the orthopaedic and overall health of children.

Obesity in Pediatric Trauma

Obese children with high-energy injuries present with more severe injuries, more extremity injuries, and higher Injury Severity Scores. They are at increased risk for complications, prolonged ventilation, and ICU stay and have increased mortality. Obesity is associated with altered bone mass accrual and higher fracture rates. Obese patients have a higher risk of loss of reduction of forearm fractures, more severe supracondylar fractures, and a higher likelihood of lateral condyle fractures. Obese patients are more likely to have complications with femur fractures and have higher rates of foot and ankle fracture.

Higher Mallampati Scores Are Not Associated with More Adverse Events During Pediatric Procedural Sedation and Analgesia

Introduction

Procedural sedation and analgesia (PSA) is used by non-anesthesiologists (NAs) outside of the operating room for several types of procedures. Adverse events during pediatric PSA that pose the most risk to patient safety involve airway compromise. Higher Mallampati scores may indirectly indicate children at risk for airway compromise. Medical governing bodies have proposed guidelines for PSA performed by NAs, but these recommendations rarely suggest using Mallampati scores in pre-PSA evaluations. Our objective was to compare rates of adverse events during pediatric PSA in children with Mallampati scores of III/IV vs. scores of Mallampati I/II.

Methods

This was a prospective, observational study. Children 18 years of age and under who presented to the pediatric emergency department (PED) and required PSA were enrolled. We obtained Mallampati scores as part of pre-PSA assessments. We defined adverse events as oxygen desaturation < 90%, apnea, laryngospasm, bag-valve-mask ventilation performed, repositioning of patient, emesis, and "other." We used chi-square analysis to compare rates of adverse events between groups.

Results

We enrolled 575 patients. The median age of the patients was 6.0 years (interquartile range = 3.1,9.9). The primary reasons for PSA was fracture reduction (n=265, 46.1%). Most sedations involved the use of ketamine (n= 568, 98.8%). Patients with Mallampati scores of III/IV were more likely to need repositioning compared to those with Mallampati scores of I/II (p=0.049). Overall, patients with Mallampati III/IV scores did not experience a higher proportion of adverse events compared to those with Mallampati scores of I/II. The relative risk of any adverse event in patients with Mallampati scores of III/IV (40 [23.8%]) compared to patients with Mallampati scores of I/II (53 [18.3%]) was 1.3 (95% confidence interval [0.91-1.87]).

Conclusion

Patients with Mallampati scores of III/IV vs. Mallampati scores of I/II are not at an increased risk of adverse events during pediatric PSA. However, patients with Mallampati III/IV scores showed an increased need for repositioning, suggesting that the sedating physician should be vigilant when performing PSA in children with higher Mallampati scores.
