Objectives: The objective of this study was to assess the prevalence, severity, and outcomes of pediatric acute respiratory distress syndrome in a resource-limited country. In addition, we sought to explore the predisposing factors that predicted the initial severity, a change from mild to moderate-severe severity, and mortality. Design: Retrospective study. Setting: PICU in Songklanagarind Hospital, Songkhla, Thailand. Patients: Children 1 month to 15 years old with acute respiratory failure admitted to the PICU from January 2013 to December 2016. Interventions: None. Measurements and Main Results: From a total of 1,738 patients admitted to PICU, 129 patients (prevalence 7.4%) were diagnosed as pediatric acute respiratory distress syndrome using the Pediatric Acute Lung Injury Consensus Conference definition. The patients were categorized by severity. Fifty-seven patients (44.2%) were mild, 35 (27.1%) were moderate, and 37 (28.1%) were severe. After multivariable analysis was performed, factors significantly associated with moderate to severe disease at the initial diagnosis were Pediatric Risk of Mortality III score (odds ratio, 1.08; 95% CI, 1.03–1.15; p = 0.004), underlying oncologic/hematologic disorder (odds ratio, 0.32; 95% CI, 0.12–0.77; p = 0.012), and serum albumin level (odds ratio, 0.46; 95% CI, 0.27–0.80; p = 0.006), whereas underlying oncologic/hematologic disorder (odds ratio, 5.33; 95% CI, 1.33–21.4) and hemoglobin (odds ratio, 0.63; 95% CI, 0.44–0.89) predicted the progression of this syndrome within 7 days. The 30-day all-cause mortality rate was 51.2% (66/129). The predictors of mortality were the Pediatric Risk of Mortality III score (odds ratio, 1.12; 95% CI, 1.02–1.24; p = 0.017), underlying oncologic/hematologic disorder (odds ratio, 7.81; 95% CI, 2.18–27.94; p = 0.002), receiving systemic steroids (odds ratio, 4.04; 95% CI, 1.25–13.03; p = 0.019), having air leak syndrome (odds ratio, 5.45; 95% CI, 1.57–18.96; p = 0.008), and presenting with multiple organ dysfunction (odds ratio, 7.41; 95% CI, 2.00–27.36; p = 0.003). Conclusions: The prevalence and mortality rate of pediatric acute respiratory distress syndrome in a developing country are high. The oncologic/hematologic comorbidity had a significant impact on the severity of progression and mortality.
Background: Chylothorax is an uncommon cause of pleural effusion in children. This study aimed to determine the characteristics, treatment strategies, and outcomes of chylothorax in children from a single institute. Methods:The 65 episodes of chylothorax in patients aged 0-15 years who were diagnosed and received treatment in Songklanagarind Hospital between January 2001 and December 2020 were retrospectively review and analyzed.Results: Of the 65 episodes, 80% were postoperative chylothorax, and were mostly related to cardiac surgery. The most common treatment strategy employed was dietary modification (64.6%). Octreotide was used as adjunctive therapy in 33.8%. Most cases of chylothorax were successfully treated by conservative treatment, while 10.7% required surgical therapy. The median time to resolution of chylothorax was 21 days [interquartile range (IQR): 8-33 days]. Young children aged <1 year were more likely to require mechanical ventilation and develop ventilator-associated pneumonia and catheter-related complications. The factors associated with death or prolonged hospitalization (>28 days) were non-postoperative chylothorax, use of total parental nutrition (TPN) >14 days, hypoalbuminemia, and ventilator-associated pneumonia.Conclusions: Most (89.2%) cases of chylothorax were successfully treated conservatively using dietary modification and octreotide therapy. The modifiable risk factors for death or prolonged hospitalization were use of TPN >14 days and hypoalbuminemia.
The study was approved by the Institutional Review Board, and written informed consent was obtained from the parents/guardians of the patients before inclusion.
We report the case of an 8-year-old boy with diffuse large B cell lymphoma who developed a right-sided spontaneous pneumothorax with pleural effusion after recovery from septic shock. The pleural fluid was thought to be malignancy-associated chylothorax concomitant with complicated pleural effusion due to a milky-like appearance, a high level of triglycerides and Gram-negative bacteria staining in the fluid. He was put on total parental nutrition and octreotide for 2 weeks, but did not improve. The laboratory results also showed a persistent bacterial infection in the pleural fluid despite appropriate antibiotics. Eventually, a CT scan revealed a fistulous tract between the right pleural cavity and the stomach. Fistula repair was successful by right open thoracotomy with decortication. Even though the gastropleural fistula is a very rare condition in paediatric patients, the physician should consider this diagnosis in a patient who has an unusual presentation or refractory chylothorax-like pleural effusion.
Appropriate sedation in mechanically ventilated patients is important to facilitate adequate respiratory support and maintain patient safety. However, the optimal sedation protocol for children is unclear. This study assessed the effectiveness of a sedation protocol utilizing the COMFORT-B sedation scale in reducing the duration of mechanical ventilation in children. This was a nonrandomized prospective cohort study compared with a historical control. The prospective cohort study was conducted between November 2015 and August 2016 and included 58 mechanically ventilated patients admitted to the pediatric intensive care unit (PICU). All patients received protocolized sedation utilizing the COMFORT-B scale, which was assessed every 12 hours after intubation by a single assessor. The prospective data were compared with retrospective data of 58 mechanically ventilated patients who received sedation by usual care from November 2014 to August 2015. Fifty percent of 116 patients were male and the mean age was 22 months (interquartile range [IQR]: 6.6–68.4). Patients in the intervention group showed no difference in the duration of mechanical ventilation (median 4.5 [IQR: 2.2–10.5] vs. 5 [IQR: 3–8.8] days). Also, there were no significant differences in the PICU length of stay (LOS; median 7 vs. 7 days, p = 0.59) and hospital LOS (median 18 vs. 14 days, p = 0.14) between the intervention and control groups. The percentages of sedative drugs, including fentanyl, morphine, and midazolam, in each group were not statistically different. The COMFORT-B scale with protocolized sedation in mechanically ventilated pediatric patients in the PICU did not reduce the duration of mechanical ventilation compared with usual care.
