Objectives. Using data from patients who developed elevations in serum creatinine concentrations while receiving continuous‐infusion lorazepam, we sought to determine the correlations between the magnitude of serum creatinine concentration rise and each of the following variables: serum propylene glycol level, cumulative lorazepam dose, and duration of lorazepam administration. An additional objective was to identify clinical markers for propylene glycol toxicity.

Osmol Gap as a Surrogate Marker for Serum Propylene Glycol Concentrations in Patients Receiving Lorazepam for Sedation

The prevalence of hyperosmolality and range of serum propylene glycol concentrations in this patient population is characterized and the amount of propylene Glycol administered to mechanically ventilated patients receiving continuous infusions of lorazepam is characterized.

Determination of a Lorazepam Dose Threshold for Using the Osmol Gap to Monitor for Propylene Glycol Toxicity

Study Objective. To determine a threshold dose for parenteral lorazepam when screening for propylene glycol toxicity with the osmol gap, and to characterize which osmol gap values are more predictive…

Propylene Glycol Accumulation After High-Dose Lorazepam: What Have We Learned?

The primary objective was to document the relationship between continuous infusion of high-dose lorazepam (HD-LZ) and serum propylene glycol (PG) concentrations 48 hrs into HD- LZ.

Assessing Propylene Glycol Toxicity in Alcohol Withdrawal Patients Receiving Intravenous Benzodiazepines: A One-Compartment Pharmacokinetic Model

It does not appear that intermittent bolus administration of intravenous benzodiazepines for alcohol withdrawal influenced renal function or anion gap regardless of number of administered doses, amount of PG received, or the estimated PG concentration.

A Prospective Evaluation of Propylene Glycol Clearance and Accumulation During Continuous-Infusion Lorazepam in Critically Ill Patients

Fifty critically ill patients receiving continuous-infusion lorazepam for a minimum of 36 hours were prospectively evaluated to determine the extent of propylene glycol accumulation over time, characterize propylene Glycol clearance in the presence of critical illness, and develop a pharmacokinetic model that would predict clearance based on patient-specific clinical, laboratory, and demographic factors.

Relationship of continuous infusion lorazepam to serum propylene glycol concentration in critically ill adults*

It is suggested that in critically ill adults with normal renal function, serum propylene glycol concentrations may be predicted by the high-dose lorazepam infusion rate and osmol gap, as reflected by a hyperosmolar anion gap metabolic acidosis.

Propylene Glycol Accumulation in Critically III Patients Receiving Continuous Intravenous Lorazepam Infusions

The continuous infusion rate and cumulative 24-hour lorazepam dose are strongly associated with and independently predict propylene glycol concentrations, and clinicians should be aware that propylene Glycol accumulation may occur with continuous-infusion lorzepam.

Acute kidney injury, hyperosmolality and metabolic acidosis associated with lorazepam

A 54-year-old male with a history of multiple admissions for alcohol intoxication received a high-dose lorazepam infusion for alcohol withdrawal during hospitalization and developed severe hyperosmolality, high anion gap metabolic acidosis, and acute kidney injury on his eighth day of hospitalization.

Propylene glycol accumulation associated with continuous infusion of lorazepam in pediatric intensive care patients

Propylene glycol accumulated significantly in pediatric intensive care patients receiving continuous lorazepam infusion, and propylene gly col concentration correlated with the cumulative lorzepam dose the patient received, however, significant laboratory abnormalities were not observed.

Short‐Term Lorazepam Infusion and Concern for Propylene Glycol Toxicity: Case Report and Review

The large PG exposure associated with long‐term cocaine‐induced renal insufficiency produced a toxic metabolic state and agents containing PG should be avoided in patients with compromised renal function induced by cocaine use.

Propylene glycol toxicity following continuous etomidate infusion for the control of refractory cerebral edema.

Etomidate, when administered by continuous infusion, has been shown to decrease cerebral metabolism resulting in a secondary decrease in cerebral blood flow with minimal changes in cerebral perfusion pressure, which decreased Intracranial pressure and cardiac parameters remained unchanged.

Clinicians should be aware of the potential for this interaction and monitor INRs or consider alternative therapy until more is known.

Propylene glycol toxicity in a patient receiving intravenous diazepam.

Hyperlactatemia, increased osmolar gap, and renal dysfunction during continuous lorazepam infusion

The vehicle of lorazepam, propylene glycol, can cause hyperlactatemia and elevated osmolar gaps, however, prophene glycol may also interfere with renal tubular function and may blunt renal compensation for respiratory acidosis.
