From the Guidelines
In patients presenting with surgical sepsis, a hybrid approach of rapid pre-operative resuscitation followed by prompt surgical intervention is recommended to balance the need for source control with the optimization of the patient's hemodynamic status. This approach is supported by the Surviving Sepsis Campaign guidelines, which emphasize the importance of early source control and fluid resuscitation in managing sepsis and septic shock 1. The guidelines recommend that a specific anatomic diagnosis of infection requiring emergent source control be sought and diagnosed or excluded as rapidly as possible, and that any required source control intervention should be implemented as soon as medically and logistically practical after the diagnosis is made.
Key components of pre-operative resuscitation include:
- Rapid administration of crystalloid fluids, with a goal of 30 mL/kg within the first hour 1
- Early broad-spectrum antibiotics, such as piperacillin-tazobactam or meropenem, depending on the suspected source of infection
- Vasopressors, such as norepinephrine, if fluid resuscitation fails to restore adequate blood pressure 1
However, certain conditions, such as necrotizing soft tissue infections or intestinal perforation with peritonitis, may require expedited surgical intervention even during resuscitation. The decision to proceed with surgery should be based on the patient's overall clinical condition, including their hemodynamic status, lactate level, and urine output.
The benefits of a hybrid approach include:
- Improved outcomes by balancing the need for source control with the optimization of the patient's hemodynamic status
- Reduced morbidity and mortality by minimizing the time to source control and optimizing tissue perfusion
- Enhanced patient safety by avoiding prolonged resuscitation or surgery in a profoundly unstable patient
Overall, the management of surgical sepsis requires a nuanced and individualized approach, taking into account the patient's specific condition and the underlying pathophysiology of sepsis. By prioritizing a hybrid approach of rapid pre-operative resuscitation followed by prompt surgical intervention, clinicians can optimize outcomes and reduce morbidity and mortality in patients with surgical sepsis 1.
From the Research
Comparative Value of Immediate Operative Intervention versus Pre-operative Resuscitation
- The optimal approach to managing patients with surgical sepsis is a topic of ongoing debate, with some studies suggesting that immediate operative intervention may be beneficial, while others advocate for pre-operative resuscitation 2, 3.
- A study published in 2021 found that increasing volumes of pre-operative fluid resuscitation were associated with higher mortality rates in patients with abdominal sepsis, although this association was not significant after adjusting for other physiologic factors 2.
- Another study published in 2024 highlighted the importance of personalized fluid resuscitation in septic peri-operative patients, suggesting that a balanced approach using dynamic haemodynamic variables may be the safest approach 4.
- The use of balanced crystalloids, such as lactated Ringer's solution or Plasma-Lyte A, has been shown to improve outcomes in patients with sepsis, particularly when used early in the resuscitation process 5.
- A study published in 2022 noted that the current evidence for fluid resuscitation in septic shock is largely based on observational or retrospective studies, and that randomized trials are needed to determine the optimal fluid strategy 6.
Key Considerations
- The amount of pre-operative fluid resuscitation does not appear to be associated with differences in time to operation, ventilator days, or hospital length of stay 2.
- The choice of fluid composition, such as balanced crystalloids versus saline, may have an impact on sepsis outcomes, particularly when used early in the resuscitation process 5.
- Personalized fluid resuscitation, taking into account individual patient factors and dynamic haemodynamic variables, may be the safest approach in septic peri-operative patients 4.
- Further research is needed to determine the optimal fluid strategy for patients with septic shock, including the use of randomized trials to compare different fluid approaches 6.
