This is a series of images that shows what one can expect to see in cases of aspiration of gastric contents.\u00a0 Aspiration of gastric contents is very common in forensic cases.\u00a0 Back in the 1960s, people used to hear that famous musicians overdosed on drugs and “choked on their own vomit.”\u00a0 This was not true, as regurgitation is a common event in death, and it is also a common result of resuscitative efforts.\u00a0 Nowadays, unless there’s some other indication that it really was involved in the death, it’s considered essentially an artifact of death.<\/p>\n

Here is a relatively low power view of a rather large bronchiole (no cartilage) filled with stomach contents from a fentanyl death:<\/p>\n

Here’s are successively higher power views:<\/p>\n

The material is easily identified.\u00a0 In the annotated image below:<\/p>\n

    \n
  1. Plant material with easily identifiable cell walls (red arrow)<\/li>\n
  2. Striated muscle (green arrow)<\/li>\n
  3. Bacterial clusters (blue arrow)<\/li>\n
  4. Amorphous debris (yellow arrow)<\/li>\n<\/ol>\n

    \"\"<\/a><\/p>\n

    The amorphous debris is often not organic, and can be birefringent:<\/p>\n

    \"\"<\/a><\/p>\n

    Gastric contents are often found outside of the larger airways, extending into alveoli.\u00a0 Here’s an example of plant material (green arrow) and meat (blue arrow) in alveolar spaces.<\/p>\n
