Interim Singapore guidelines for basic and advanced life support for paediatric patients with suspected or confirmed COVID-19

The COVID-19 pandemic has resulted in significant challenges for the resuscitation of paediatric patients, especially for infants and children who are suspected or confirmed to be infected. Thus, the paediatric subcommittee of the Singapore Resuscitation and First Aid Council developed interim modifications to the current Singapore paediatric guidelines using extrapolated data from the available literature, local multidisciplinary expert consensus and institutional best practices. It is hoped that this it will provide a framework during the pandemic for improved outcomes in paediatric cardiac arrest patients in the local context, while taking into consideration the safety of all community first responders, medical frontline providers and healthcare workers.     

Gastric ulcer localization by direct in vivo labeling of sucralfate. Work in progress

We developed and evaluated a new procedure for imaging gastric ulcer disease with technetium 99m-labeled sucralfate. The new method employs direct in vivo labeling of sucralfate instead of in vitro labeling using human serum albumin, as previously reported in the literature. Tests using hydrochloric acid and a rabbit ulcer model showed the efficacy of the direct in vivo labeling technique and the ability of the tagged material to bind to ulcers, respectively. In 26 studies using humans with sucralfate labeled directly in vivo, 15 gave true-negative results and 11 gave true-positive results. Of 14 studies using humans with in vitro labeled sucralfate, three gave true-negative results, three gave true-positive results, and the results of eight were either false-negative or could not be interpreted because of high levels of activity remaining in the stomach. We suggest that the direct in vivo labeling method significantly improves the sucralfate gastric ulcer imaging technique.
