Browse categories and answer follow-up questions to refine your symptom profile.
Triage and immediate priorities
High-risk presentation
Peritonitis
Rigid abdomen
Rebound tenderness
Sepsis physiology
SBP < 90 mmHg
Lactate >= 2 mmol/l
Complicated disease risk
Immunocompromised state
Significant comorbidity burden
Monitoring and access
Continuous pulse oximetry
Escalate if SpO2 < 92%
Supplemental oxygen if hypoxemia
Cardiac monitoring if shock concern
Persistent tachycardia > 120/min
Persistent hypotension after fluids
IV access
Two large-bore IVs for shock concern
Consider IO if unable to obtain
Resuscitation triggers
If septic shock physiology, initiate sepsis pathway
Crystalloid bolus 20-30 ml/kg
Broad-spectrum IV antibiotics within 1 hour
If generalized peritonitis, immediate surgical consult
NPO status
NG tube if vomiting or ileus
If severe uncontrolled pain, escalation
Parenteral analgesia
Reassess for perforation or abscess
Early decisions
Working diagnosis framework
Uncomplicated diverticulitis
Localized inflammation
No abscess, fistula, obstruction, perforation
Complicated diverticulitis
Abscess
Free perforation with peritonitis
Alternative diagnosis concern
Right lower quadrant pain
Hematuria or colicky pain
Imaging urgency
Immediate CT A/P with IV contrast if unstable or peritonitis
Identify perforation and source control needs
Identify drainable abscess
Deferred CT acceptable if classic mild recurrent episode and stable
Prior imaging-confirmed diverticulitis
No red flags for complicated disease
Early consult triggers
Surgery
Peritonitis
Obstruction
Interventional radiology
Abscess >= 3 cm
Abscess not responding to antibiotics
