Continuous Pectoral Fascia Blocks for Postoperative Analgesia After Median Sternotomy: A Case Report.

We report a novel case of a patient who presented for aortic valve replacement via median sternotomy. Bilateral continuous pectoral fascia blocks were placed to provide postoperative analgesia. Both numerical rating scale pain scores and opioid consumption after surgery were suggestive of analgesic benefit.

Reexamining the risks of drinking-water nitrates on public health.

Background: Nitrates in drinking water are generally considered the sole source of nitrite poisoning with methemoglobinemia in infantile methomoglobinemia (IM). However, IM, which occurs during the first 4 months of life, is actually a constellation of cyanosis and hypoxia associated with methemoglobinemia that can result from several other causes.

Methods: This review reexamines the role of nitrate levels in drinking water as a cause of IM and identifies other sources of nitrates that can affect public health and cause chronic diseases.
