From the Guidelines
I would recommend adding norepinephrine as the first-choice vasopressor to target a mean arterial pressure (MAP) of 65 mm Hg, as the patient's persistent hypotension despite midodrine and ephedrine doses is a concern for sepsis-induced hypoperfusion 1. The patient's clinical presentation, including elevated temperature, increased oxygen requirements, wheezing, and reported change in sputum color, suggests a lower respiratory tract infection (LRTI) with a potential bronchospastic component. Given the patient's hypotension, I would closely monitor his response to the fluid challenge and consider adding vasopressors if hypotension persists despite adequate fluid resuscitation, as recommended by the Surviving Sepsis Campaign guidelines 1. The use of dynamic measures, such as pulse pressure variation, to predict fluid responsiveness may also be helpful in guiding fluid management 1. Additionally, I would recommend adding corticosteroids (such as prednisolone 30-40mg daily for 5-7 days) to address the significant wheezing, which suggests a bronchospastic component to the infection. Early imaging, such as a chest X-ray, should be performed as soon as possible to confirm the diagnosis of LRTI and rule out other conditions like pulmonary edema or pneumothorax. Appropriate antibiotics (already initiated with Tazocin), bronchodilators, and potentially corticosteroids will provide comprehensive management of both the infection and associated bronchospasm while monitoring for clinical improvement. It is also essential to closely monitor the patient's urine output, as sepsis-induced hypoperfusion can lead to acute kidney injury, and consider further hemodynamic assessment, such as echocardiography, to determine the cause of the hypotension 1.
From the Research
Assessment and Plan
The patient's condition is being managed with a focus on addressing the lower respiratory tract infection (LRTI) and hypotension. The current plan includes:
- Administering IV tazocin as per the SOS antibiotics protocol
- Collecting blood and blood cultures, as well as sputum and urine cultures
- Monitoring blood pressure and considering IV fluids if necessary
- Maintaining oxygen saturation levels above 94%
- Administering paracetamol as needed
- Considering a chest X-ray if the patient's condition does not improve
Considerations for Hypotension Management
The patient is currently receiving midodrine and ephedrine to manage hypotension. Studies have shown that midodrine is effective in increasing standing blood pressure and improving symptoms of orthostatic hypotension 2, 3. However, the patient's persistent hypotension despite receiving a total of 20mg midodrine and 15mg ephedrine suggests that alternative treatments may be necessary. Norepinephrine has been shown to be more effective than midodrine/octreotide in certain cases 4.
Additional Considerations
The patient's temperature is elevated at 38.0°C, and they have reported feeling unwell. The presence of a polyphonic wheeze on auscultation and the change in sputum color suggest a respiratory infection. The patient's urine output is adequate, and there is no evidence of peripheral edema.
Potential Additions to the Plan
- Consider adding a bronchodilator to help manage the patient's wheezing and respiratory distress
- Monitor the patient's temperature and adjust the antibiotic treatment as necessary
- Continue to monitor the patient's blood pressure and adjust the treatment plan as needed to ensure adequate blood pressure management
- Consider alternative treatments for hypotension, such as norepinephrine, if the patient's condition does not improve with current treatment 4
