ABSTRACT

BACKGROUND: Little data exist regarding the practice of sodium management in acute neurologically injured patients. This study describes the practice variations, thresholds for treatment, and effectiveness of treatment in this population. METHODS: This retrospective, multicenter, observational study identified 400 ICU patients, from 17 centers, admitted for ≥48 h with subarachnoid hemorrhage (SAH), traumatic brain injury (TBI), intraparenchymal hemorrhage, or intracranial tumors between January 1, 2011 and July 31, 2012. Data collection included demographics, APACHE II, Glascow Coma Score (GCS), serum sodium (Na+), fluid rate and tonicity, use of sodium-altering therapies, intensive care unit (ICU) and hospital length of stay, and modified Rankin score upon discharge. Data were collected for the first 21 days of ICU admission or ICU discharge, whichever came first. Sodium trigger for treatment defined as the Na+ value prior to treatment with response defined as an increase of ≥4 mEq/L at 24 h. RESULTS: Sodium-altering therapy was initiated in 34 % (137/400) of patients with 23 % (32/137) having Na+ >135 mEq/L at time of treatment initiation. The most common indications for treatment were declining serum Na+ (68/116, 59 %) and cerebral edema with mental status changes (21/116, 18 %). Median Na+ treatment trigger was 133 mEq/L (IQR 129-139) with no difference between diagnoses. Incidence and treatment of hyponatremia was more common in SAH and TBI [SAH (49/106, 46 %), TBI (39/97, 40 %), ICH (27/102, 26 %), tumor (22/95, 23 %); p = 0.001]. The most common initial treatment was hypertonic saline (85/137, 62 %), followed by oral sodium chloride tablets (42/137, 31 %) and fluid restriction (15/137, 11 %). Among treated patients, 60 % had a response at 24 h. Treated patients had lower admission GCS (12 vs. 14, p = 0.02) and higher APACHE II scores (12 vs. 10, p = 0.001). There was no statistically significant difference in outcome when comparing treated and untreated patients. CONCLUSION: Sodium-altering therapy is commonly employed among neurologically injured patients. Hypertonic saline infusions were used first line in more than half of treated patients with the majority having a positive response at 24 h. Further studies are needed to evaluate the impact of various treatments on patient outcomes.

ABSTRACT

PURPOSE: The frequency with which atypical antipsychotics initiated in the intensive care unit (ICU) is unknown. While there is lack of evidence to support the exact duration of treatment, antipsychotics should not be continued chronically for agitation and psychosis related to critical illness. The objective of this study was to determine whether atypical antipsychotics initiated in the ICU at a large tertiary academic medical center were continued after hospital discharge. Safety outcomes were also assessed. MATERIALS: A total of 1023 patients who received atypical antipsychotics during ICU stay were identified. Patients were assessed in a pseudo-randomized fashion until a sample of 191 patients was reached. After review of the exclusion criteria, the final study population was 100 patients. When antipsychotics were discontinued, progress notes were reviewed to identify the reason for discontinuation. Safety outcomes were assessed based on physician documentation in the medical charts. RESULTS: Atypical antipsychotics were continued in 23% of patients. Atypical antipsychotics were discontinued in 1 patient due to QTc prolongation. CONCLUSIONS: Atypical antipsychotics initiated in the ICU are frequently continued after hospital discharge. Given the known risks associated with extended therapy, initiatives are needed to prevent inappropriate continuation.

ABSTRACT

Seizures are a well-described complication of acute brain injury and neurosurgery. Antiepileptic drugs (AEDs) are frequently utilized for seizure prophylaxis in neurocritical care patients. In this review, the Neurocritical Care Society Pharmacy Section describes the evidence associated with the use of AEDs for seizure prophylaxis in patients with intracerebral tumors, traumatic brain injury, aneurysmal subarachnoid hemorrhage, craniotomy, ischemic stroke, and intracerebral hemorrhage. Clear evidence indicates that the short-term use of AEDs for seizure prophylaxis in patients with traumatic brain injury and aneurysmal subarachnoid hemorrhage may be beneficial; however, evidence to support the use of AEDs in other disease states is less clear.

ABSTRACT

BACKGROUND: Numerous anticonvulsant agents are now available for treating status epilepticus (SE). However, a paucity of data is available to guide clinicians in the initial treatment of seizures or SE. This study describes the current strategies being employed to treat SE in the U.S.A. METHODS: Fifteen American academic medical centers completed a retrospective, multicenter, observational study by reviewing 10-20 of the most recent cases of SE at their institution prior to December 31, 2009. A multivariate analysis was performed to determine factors associated with cessation of seizures. RESULTS: A total of 150 patients were included. Most patients with SE had a seizure disorder (58%). SE patients required a median of 3 AEDs for treatment. Three quarters of patients received a benzodiazepine as first-line therapy (74.7%). Phenytoin (33.3%) and levetiracetam (10%) were commonly used as the second AED. Continuous infusions of propofol, barbiturate, or benzodiazepine were used in 36% of patients. Median time to resolution of SE was 1 day and was positively associated with presence of a complex partial seizure, AED non-compliance prior to admission, and lorazepam plus another AED as initial therapy. Prolonged ICU length of stay and topiramate therapy prior to admission were negatively associated with SE resolution. Mortality was higher in patients without a history of seizure (22.2 vs. 6.9%, p = 0.006). CONCLUSIONS: The use of a benzodiazepine followed by an AED, such as phenytoin or levetiracetam, is common as first and second-line therapy for SE and appears to be associated with a shorter time to SE resolution. AED selection thereafter is highly variable. Patients without a history of seizure who develop SE had a higher mortality rate.
