RESUMO
PresentationAn 83-year-old man presented for headache and altered mental status. Four days prior, he underwent endoscopic sinus surgery for nasal polyps. Over the two previous days, he gradually developed a headache and was brought to the emergency department when his wife noted mild confusion and generalised weakness. His examination was notable for a heart rate of 101 beats per minute, clear nasal discharge, meningismus and confusion to the date with generalised weakness. A lumbar puncture revealed cloudy cerebrospinal fluid (CSF) with a white blood cell count of 3519x10Ë9/L (95% neutrophils). A CT scan of the head was obtained (figure 1).emermed;38/7/519/F1F1F1Figure 1Non-contrast CT scan of the head in axial plane. QUESTION: What is the appropriate next step in management?Obtain MRI of the brain to localise ischaemic damage.Administer broad-spectrum antibiotics, including pseudomonal coverage.Consult otolaryngology to arrange functional endoscopic sinus surgery for CSF leak closure.Consult neurosurgery for surgical decompression of mass lesion(s).

OBJECTIVE: The objective was to determine the proportion of patients with pulmonary embolism (PE) treated with unfractionated heparin (UFH) who achieved therapeutic activated partial thromboplastin time (aPTT) values within 48 hours of treatment. METHODS: Retrospective analysis of a PE response team (PERT) database was performed at a large, urban, academic teaching hospital. Inclusion criteria were adult patients with acute PE for whom the PERT was consulted and who received anticoagulation (AC) with UFH according to guideline standard dosing. aPTT values during 6-hour time periods during the first 48 hours of AC were collected and analyzed. RESULTS: A total of 505 patients met inclusion criteria. For patients receiving a bolus and infusion of UFH, the proportions (95% confidence interval [CI]) of patients in the therapeutic range were 19.0% (14.2% to 25.0%) at 12 hours, 26.3% (26.3% to 33.1%) at 24 hours, 28.3% (22.0% to 35.4%) at 36 hours, and 28.4% (20.8% to 37.5%) at 48 hours. For titrated infusion only, the proportions (95% CIs) of patients were 23.3% (16.2% to 32.3%) at 12 hours, 41.4% (31.6% to 51.9%) at 24 hours, 37.0% (26.8% to 48.5%) at 36 hours, and 42.1% (30.2% to 55.0%) at 48 hours. No patient had all therapeutic aPTT values. CONCLUSIONS: The majority of patients with acute PE spend most of their first 48 hours outside of the therapeutic range of AC when treated with guideline standard dosing of UFH. Over half of the patients fail to achieve any therapeutic PTT level within 24 hours of UFH initiation, and no patient had all therapeutic aPTTs. Future research should focus on identifying factors associated with achieving therapeutic AC with UFH.
