Utility of Point-of-care Ultrasound in Children With Pulmonary Tuberculosis.

ABSTRACT: BACKGROUND:Point-of-care ultrasound (POCUS) detects extrapulmonary tuberculosis (EPTB) in HIV infected adults but has not been evaluated in children despite their higher risk of EPTB. This study's aims were to investigate feasibility of POCUS for EPTB in children, frequency of POCUS findings suggestive of EPTB and time to sonographic resolution of findings with treatment. METHODS:This prospective South African cohort study enrolled children with suspected pulmonary tuberculosis (PTB). POCUS for pleural, pericardial or ascitic effusion, abdominal lymphadenopathy or splenic or hepatic microabscesses was performed and repeated at 1, 3 and 6 months of tuberculosis (TB) treatment. Prevalence of POCUS findings and their association with HIV infection was investigated in children with confirmed PTB (microbiologically proven), unconfirmed PTB (clinically diagnosed) or unlikely TB (respiratory disease that improved during follow-up without TB treatment). RESULTS:Of 232 children [median age 37 months (interquartile range, 18-74)], 39 (17%) were HIV infected. Children with confirmed or unconfirmed PTB had a higher prevalence of POCUS findings than children with unlikely TB [18 of 58 (31%) and 36 of 119 (30%) vs. 8 of 55 (15%); P = 0.04 and P = 0.03, respectively]. Pleural effusion [n = 30 (13%)] or abdominal lymphadenopathy [n = 28 (12%)] were the most common findings; splenic microabscesses [n = 12 (5%)] were strongly associated with confirmed PTB. Children coinfected with HIV and TB were more likely than HIV-uninfected children with TB to have abdominal lymphadenopathy (37% vs. 10%; P < 0.001) or splenic microabscesses (23% vs. 3%; P < 0.001]. Most ultrasound findings were resolved by 3 months with appropriate TB treatment. CONCLUSIONS:POCUS for EPTB in children with PTB is feasible. The high prevalence of findings suggests that POCUS can contribute to timely diagnosis of childhood TB and to monitoring treatment response.

Project description:IntroductionPoint-of-care ultrasound (POCUS) use is increasing in pediatric clinical settings. However, gastric POCUS is rarely used, despite its potential value in optimizing the diagnosis and management in several clinical scenarios (i.e., assessing gastric emptying and gastric volume/content, gastric foreign bodies, confirming nasogastric tube placement, and hypertrophic pyloric stenosis). This review aimed to assess how gastric POCUS may be used in acute and critically ill children.Materials and methodsAn international expert group was established, composed of pediatricians, pediatric intensivists, anesthesiologists, radiologists, nurses, and a methodologist. A scoping review was conducted with an aim to describe the use of gastric POCUS in pediatrics in acute and critical care settings. A literature search was conducted in three databases, to identify studies published between 1998 and 2022. Abstracts and relevant full texts were screened for eligibility, and data were extracted, according to the JBI methodology (Johanna Briggs Institute).ResultsA total of 70 studies were included. Most studies (n = 47; 67%) were conducted to assess gastric emptying and gastric volume/contents. The studies assessed gastric volume, the impact of different feed types (breast milk, fortifiers, and thickeners) and feed administration modes on gastric emptying, and gastric volume/content prior to sedation or anesthesia or during surgery. Other studies described the use of gastric POCUS in foreign body ingestion (n = 6), nasogastric tube placement (n = 5), hypertrophic pyloric stenosis (n = 8), and gastric insufflation during mechanical ventilatory support (n = 4). POCUS was performed by neonatologists, anesthesiologists, emergency department physicians, and surgeons. Their learning curve was rapid, and the accuracy was high when compared to that of the ultrasound performed by radiologists (RADUS) or other gold standards (e.g., endoscopy, radiography, and MRI). No study conducted in critically ill children was found apart from that in neonatal intensive care in preterms.DiscussionGastric POCUS appears useful and reliable in a variety of pediatric clinical settings. It may help optimize induction in emergency sedation/anesthesia, diagnose foreign bodies and hypertrophic pyloric stenosis, and assist in confirming nasogastric tube placement, avoiding delays in obtaining confirmatory examinations (RADUS, x-rays, etc.) and reducing radiation exposure. It may be useful in pediatric intensive care but requires further investigation.
