OBJECTIVES: In mechanically ventilated patients, awareness with paralysis (AWP) can have devastating consequences, including post-traumatic stress disorder (PTSD), depression, and thoughts of suicide. Single-center data from the emergency department (ED) demonstrate an event rate for AWP factors higher than that reported from the operating room. However, there remains a lack of data on AWP among critically ill, mechanically ventilated patients. The objective was to assess the proportion of ED patients experiencing AWP and investigate modifiable variables associated with its occurrence. DESIGN: An a priori planned secondary analysis of a multicenter, prospective, before-and-after clinical trial. SETTING: The ED of three academic medical centers. PATIENTS: Mechanically ventilated adult patients that received neuromuscular blockers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All data related to sedation and analgesia were collected. AWP was the primary outcome, assessed with the modified Brice questionnaire, and was independently adjudicated by three expert reviewers. Perceived threat, in the causal pathway for PTSD, was the secondary outcome. A total of 388 patients were studied. The proportion of patients experiencing AWP was 3.4% (n = 13), the majority of whom received rocuronium (n = 12/13; 92.3%). Among patients who received rocuronium, 5.5% (n = 12/230) experienced AWP, compared with 0.6% (n = 1/158) among patients who did not receive rocuronium in the ED (odds ratio, 8.64; 95% CI, 1.11–67.15). Patients experiencing AWP had a higher mean (sd) threat perception scale score, compared with patients without AWP (15.6 [5.8] vs 7.7 [6.0]; p < 0.01). CONCLUSIONS: AWP was present in a concerning proportion of mechanically ventilated ED patients, was associated with rocuronium exposure in the ED, and led to increased levels of perceived threat, placing patients at greater risk for PTSD. Studies that aim to further quantify AWP in this vulnerable population and eliminate its occurrence are urgently needed.

Status epilepticus (SE) is continuous clinical and/or electrographic seizures lasting 5 minutes or more without recovery and carries a high mortality. Medication management varies by institution, as well as administration, combination of antiepileptic drugs (AEDs), and dosing. Single-center retrospective review of medication management of SE patients admitted to West Virginia University Hospital before and after neurointensivist implemented guidelines. Patients admitted between January 2012 and June 2014 were grouped in the prior to neurointensivist group (pre-NI) and patients admitted between July 2014 and June 2016 were grouped in the postneurointensivist group (post-NI). Baseline demographics, hospital, intensive care unit (ICU), and ventilator length of stay were recorded. Medications reviewed included number of AEDs and maximum dose of lorazepam, phenytoin, levetiracetam, and lacosamide. Outcomes included number of continuous infusions of either midazolam or propofol at seizure suppression doses as well as pentobarbital, phenobarbital, or ketamine, and need for vasopressor use. Of the 74 patients included, the pre-NI group (n = 40) utilized more AEDs (6 vs 4) compared with the post-NI group (n = 34). The pre-NI group had less midazolam continuous infusions meeting seizure suppression doses (8 vs 9), but higher average doses (49 vs 27 mg/h) compared with the post-NI group. More patients in the pre-NI group were on propofol seizure suppression doses (15 vs 10) and phenobarbital continuous infusions (11 vs 2) than the post-NI group. Patients had less vasopressor use in the post-NI group than the pre-NI group (11 vs 23). Frequency and dosing of lorazepam, phenytoin, levetiracetam, and lacosamide were similar between the 2 groups. Ventilator use, hospital, and ICU length of stay were also similar between groups. Implementation of a neurointensivist and medication guidelines resulted in fewer AEDs and less vasopressor use in the management of SE. Midazolam use was slightly higher in the post-NI group but at lower doses overall.

Background: The purpose of this study was to evaluate if dosing fentanyl, dexmedetomidine, and propofol based on ideal or adjusted vs actual weight in patients would decrease overall opioid and sedative use. Methods: This was a retrospective chart review comparing adjusted vs actual weight-based dosing protocol of mechanically ventilated (MV) intensive care unit (ICU) adult patients who required fentanyl and either propofol or dexmedetomidine. Results: A total of 261 patients were included in which 101 patients were in the actual weight group and 160 patients were in the adjusted weight group. Total doses per MV day of fentanyl was 1042 ± 1060 µg in the actual weight group vs 901 ± 1025 µg in the adjusted weight group (P = .13). Total doses per MV day of midazolam was 20 ± 19 mg in the actual group vs 15 ± 19 mg adjusted group (P = .02). Average MV days was 8.2 vs 7.1 days, ICU length of stay was 10.6 vs 9.4 days, and self-extubation rates were 17.8% vs 4.4% in the actual group and adjusted group, respectively. Conclusion: Total midazolam doses per MV day were lower in the adjusted group. No significant change was seen in MV days, ICU length of stay, or self-extubation rates.
