Blood Purification in Toxicology:Reviewing the Evidence and Providing Recommendations
Salicylates
General Recommendation
-
ECTR is recommended in severe salicylate poisoning (1D)
Indications
ECTR is recommended if ANY of the following are met:
-
If [salicylate] > 7.2 mmol/L (100 mg/dL) (1D)
-
If [salicylate] > 6.5 mmol/L (90 mg/dL) in the presence of impaired kidney function (1D)
-
In the presence of altered mental status (1D)
-
In the presence of new hypoxemia requiring supplemental oxygen (1D)
-
If standard therapy (supportive measures, bicarbonate, etc.) fails (1D)
ECTR is suggested if ANY of the following are met:
-
If [salicylate] > 6.5 mmol/L (90 mg/dL) (2D)
-
If [salicylate] > 5.8 mmol/L (80 mg/dL) in the presence of impaired kidney function (2D)
-
If the systemic pH is ≤ 7.20 (2D)
Cessation of ECTR is indicated if:
-
Clinical improvement is apparent (1D) and
-
[salicylate] < 1.4 mmol/L (19 mg/dL) (1D) or ECTR has been performed for a period of at least 4-6 h when salicylate concentrations are not readily available (2D)
Choice of ECTR
-
Intermittent HD is the preferred modality in patients with salicylate poisoning (1D)
-
The following are acceptable alternative if HD is not available:
-
Intermittent HP (1D)
-
CRRT (3D)
-
Exchange transfusion in neonates (1D)
-
Miscellaneous
-
It is recommended to continue intravenous bicarbonate therapy between ECTR sessions (1D).
