From the Guidelines
The next best step in managing this patient is to arrange follow-up paracentesis to confirm the resolution of spontaneous bacterial peritonitis (SBP) and to assess the effectiveness of the current antibiotic treatment with ceftriaxone, as recommended by the most recent guidelines 1. This patient has SBP due to E. coli with hypotension and gastrointestinal bleeding, already being treated with appropriate antibiotics and medications to control bleeding. The resolution of SBP should be proven by demonstrating a decrease of ascitic neutrophil count to <250/mm3 and sterile cultures of ascitic fluid, if positive at diagnosis, as stated in the guidelines 1. A second paracentesis after 48 h of start of treatment may help guide the effect of antibiotic therapy, and failure of antibiotic therapy should be suspected if there is worsening of clinical signs and symptoms and/or no marked reduction or increase in ascitic fluid neutrophil count compared to levels at diagnosis 1. Additionally, the patient should receive fluid resuscitation with crystalloids to address hypotension, with careful monitoring of vital signs, urine output, and mental status. Blood products like packed red blood cells may be needed if significant bleeding continues. Early consideration for endoscopic intervention is warranted if the gastrointestinal bleeding is severe or uncontrolled. The patient should also be monitored closely for signs of hepatic encephalopathy, renal dysfunction, and other complications of decompensated liver disease that commonly accompany SBP, as recommended by the guidelines 1. Intravenous albumin may also be considered to improve circulatory function and reduce the risk of hepatorenal syndrome and mortality in SBP patients, as suggested by the guidelines 1. However, the most immediate next step is to arrange follow-up paracentesis to assess the resolution of SBP and the effectiveness of the current treatment. The use of prophylactic antibiotics, such as ceftriaxone, is recommended in patients with acute variceal bleeding to reduce the incidence of bacterial infections and improve survival, as stated in the guidelines 1. The patient's hypotension and gastrointestinal bleeding should be managed concurrently, with careful consideration of the potential complications of decompensated liver disease. Overall, the management of this patient requires a comprehensive approach that addresses the SBP, gastrointestinal bleeding, and potential complications of decompensated liver disease.

From the Research
Patient Management
The patient is already on intravenous (IV) proton pump inhibitor, IV octreotide, and IV ceftriaxone for spontaneous bacterial peritonitis (SBP). Considering the patient's hypotension (blood pressure 95/60 mm Hg) and gastrointestinal bleeding, the next best step would be to address the hypotension.
- The patient's low blood pressure could be due to hypovolemia, which is a common complication in patients with gastrointestinal bleeding and SBP.
- According to the study 2, hydroxyethylstarch (HES) is a promising fluid in preserving blood volume, comparable to albumin, but superior to saline.
- However, the study 2 does not directly address the use of normal saline bolus infusion in hypotensive patients with gastrointestinal bleeding and SBP.
- Given the patient's current condition, initiating a normal saline bolus infusion could be considered to rapidly expand the intravascular volume and improve blood pressure.
Considerations for Other Options
- Arranging follow-up paracentesis (Option A) may be necessary to monitor the patient's response to treatment for SBP, but it does not directly address the patient's current hypotension.
- Starting prophylactic antibiotics on discharge (Option B) may be considered to prevent future episodes of SBP, but it is not the immediate priority in managing the patient's current condition.
- Initiating nonselective beta blocker (Option D) may be considered for long-term prevention of rebleeding in patients with esophageal varices, but it is not the immediate priority in managing the patient's current hypotension and gastrointestinal bleeding, as suggested by studies 3 and 4.
