What is the management for a patient with a ruptured ovarian tumor in septic shock?

Management of Ruptured Ovarian Tumor in Septic Shock

A patient with a ruptured ovarian tumor in septic shock requires immediate simultaneous resuscitation and urgent surgical source control—begin aggressive fluid resuscitation with at least 30 mL/kg crystalloid within 3 hours, start broad-spectrum antibiotics within 1 hour, initiate norepinephrine if hypotension persists despite fluids, and proceed to emergency surgery for source control as soon as the patient is medically stabilized. 1, 2

Immediate Resuscitation (First 3 Hours)

Fluid Resuscitation

• Administer at least 30 mL/kg of IV crystalloid fluid within the first 3 hours using either balanced crystalloids or normal saline as the first-choice fluid 1, 2
• Continue fluid administration using a challenge technique—give additional fluids as long as hemodynamic parameters (blood pressure, heart rate, urine output, mental status) continue to improve 1, 2
• Use dynamic measures of fluid responsiveness (pulse pressure variation, stroke volume variation) when available rather than static measures like central venous pressure 1, 2
• Consider adding albumin if the patient requires substantial amounts of crystalloids 1, 2
• Avoid hydroxyethyl starches completely as they increase acute kidney injury and mortality risk 1, 2

Critical Pitfall: Fluid Overload

• While aggressive initial resuscitation is mandatory, avoid overly aggressive fluid resuscitation in patients with abdominal sepsis as this can increase intra-abdominal pressure, worsen bowel edema, and lead to abdominal compartment syndrome 2
• Monitor for signs of fluid overload and intra-abdominal hypertension, particularly after forced abdominal closure 2

Vasopressor Therapy

• Initiate norepinephrine as the first-choice vasopressor if the patient remains hypotensive despite adequate fluid resuscitation 1, 2
• Target a mean arterial pressure (MAP) of 65 mmHg initially 2, 1
• Add epinephrine if additional vasopressor support is needed to maintain adequate blood pressure 1
• Avoid dopamine due to increased risk of tachyarrhythmias 2

Antimicrobial Therapy (Within 1 Hour)

• Administer broad-spectrum antimicrobials within the first hour of recognition of septic shock 1
• Obtain at least two sets of blood cultures before starting antimicrobials if this does not significantly delay therapy 1
• Empiric coverage should be broad enough to cover all likely pathogens including gram-negative organisms, anaerobes, and gram-positive cocci given the intra-abdominal source 1
• Reassess antimicrobial regimen daily for potential de-escalation once pathogen identification and sensitivities are established 1

Clinical Context

• Ruptured ovarian tumors can cause life-threatening sepsis from purulent fluid release into the peritoneal cavity, as documented in cases with Staphylococcus aureus and other organisms 3, 4

Urgent Surgical Source Control

Timing and Approach

• Identify the specific anatomic diagnosis requiring source control as rapidly as possible and implement surgical intervention as soon as medically and logistically practical, ideally within 12 hours of diagnosis 1, 2
• The ruptured ovarian tumor represents a definitive source requiring emergent surgical intervention 2
• Proceed to emergency laparotomy or laparoscopy (if hemodynamically stable enough) once initial resuscitation has begun 3, 5

Surgical Objectives

• Remove the ruptured ovarian mass (salpingo-oophorectomy) 3, 5
• Evacuate purulent or hemorrhagic fluid from the peritoneal cavity 3, 4
• Perform thorough abdominal lavage with large volumes of normal saline (typically 4000+ mL) 4
• Assess for other pathology requiring intervention 3
• Use the intervention associated with the least physiologic insult when possible 2

Critical Pitfall: Delayed Source Control

• Do not delay surgical intervention once the patient has received initial resuscitation—delays in source control are associated with increased mortality in intra-abdominal infections 2
• The patient does not need to be completely hemodynamically normalized before surgery; proceed once adequate resuscitation has begun and the patient can tolerate anesthesia 2

Ongoing Monitoring and Reassessment

Hemodynamic Monitoring

• Continuously monitor vital signs including heart rate, blood pressure, oxygen saturation, respiratory rate, and urine output (target >0.5 mL/kg/h) 2, 1
• Guide resuscitation to normalize lactate levels as a marker of adequate tissue perfusion 1
• Reassess hemodynamic status frequently through clinical examination and available physiologic variables 1
• Consider ultrasound measurement of IVC diameter for defining fluid requirements 2

Respiratory Support

• Maintain head of bed elevated 30-45 degrees to limit aspiration risk 2
• If mechanical ventilation is required, use lung-protective ventilation strategies with tidal volumes of 6 mL/kg predicted body weight 2

Glucose Control

• Target blood glucose ≤180 mg/dL using a protocolized approach once the patient is stabilized 2

Additional Supportive Care

• Provide stress ulcer prophylaxis with proton pump inhibitor or H2-blocker given bleeding risk factors 2
• Initiate VTE prophylaxis with low-molecular-weight heparin or unfractionated heparin once bleeding risk is controlled 2

Special Considerations

Intra-abdominal Pressure Monitoring

• Monitor for intra-abdominal hypertension and abdominal compartment syndrome, particularly after aggressive fluid resuscitation and abdominal surgery 2
• Consider leaving the abdomen open or using temporary closure techniques if significant bowel edema or concern for compartment syndrome exists 2

Pathology Assessment

• Send all surgical specimens for histopathological examination as ruptured ovarian tumors may reveal unexpected findings including malignancy, endometriomas with infection, or metastatic disease 3, 4, 5
• Microbiological cultures from peritoneal fluid guide antibiotic de-escalation 4
