Anaphylactic shock associated with intravenous thrombolytics: case report and an analysis from adverse event reporting system.
Adverse events including intracerebral hemorrhage and reperfusion arrhythmias are well known to occur with thrombolytic therapy. We report a case report of anaphylactic reaction directly attributable to intravenous (IV) recombinant tissue plasminogen activator and identify additional cases through review of the Food and Drug Administration Adverse Event Reporting System. A systematic review of Adverse Event Reporting System was performed for allergic adverse events occurring in conjunction with IV thrombolytics. ⋯ There was 1 death directly attributable to allergic reaction in a patient who received IV reteplase for MI. Although IV alteplase is identical to endogenous tissue plasminogen activator, it appears to be the most common cause of allergic reaction among currently used thrombolytics, with or without concomitant administration of angiotensin-converting enzyme inhibitors. A greater awareness among physicians may result in prompt recognition and treatment.

Studies investigating the relationship between blood gas tension and outcome in cardiac arrest survivors have reported conflicting results. This might have resulted from the use of a blood gas value at a single time point and the difference in the proportion of patients treated with therapeutic hypothermia (TH). We investigated the association of the mean blood gas tensions calculated from blood gas values obtained between restoration of spontaneous circulation and end of TH with the outcome in cardiac arrest patients treated with TH. ⋯ Mean Pao2 had no independent association with in-hospital mortality whereas hypocarbia was independently associated with in-hospital mortality. We also found a V-shaped independent association between the mean Pao2 and poor neurologic outcome at hospital discharge.

Propofol for benzodiazepine-refractory alcohol withdrawal in a non-mechanically ventilated patient: a case report.
Long-term alcohol use confers neurochemical changes in response to alcohol's exogenous inhibitory effects. Downregulation and decreased sensitivity of γ-aminobutyric acid receptors render benzodiazepines less effective at controlling psychomotor agitation. ⋯ Successful use of propofol in refractory AWS in patients with endotracheal intubation and mechanical ventilation has been reported. We present a case of resolution of AWS symptoms in a benzodiazepine-refractory, nonintubated, non-mechanically ventilated alcohol withdrawal patient with low-dose, continuous-infusion propofol.
