Association of acetaminophen testing results with standard clinical markers of enteral tolerance
| Detectable acetaminophen concentration (n = 9) | Undetectable acetaminophen concentration (n = 11) | P‐value | |||
|---|---|---|---|---|---|
| Ileus on imaging, n (%) a | n = 5 | 1 (20) | n = 8 | 7 (88) | .03 |
| Rate of TFs at 24 h (ml/h), median (interquartile range) | 40 (35–45) | 10 (0–25) | . 01 | ||
| Total residuals at 24 h (ml), median (interquartile range) b | n = 4 | 45 (7.5–112.5) | n = 7 | 830 (115–960) | .11 |
| TFs resumed, n (%) | 8 (89) | 8 (73) | .59 | ||
Abbreviation: TF, tube feeds.
a
Seven patients did not have abdominal imaging (four patients in the detectable acetaminophen concentration group and three patients in the undetectable acetaminophen concentration group). These individuals were analyzed as missing data.
b
Nine patients did not have documented gastric residual volumes (five patients in the detectable acetaminophen concentration group and four patients in the undetectable acetaminophen concentration group). These individuals were analyzed as missing data.
