From the Guidelines
The prognosis for a patient who underwent an emergency right decompressive craniectomy, expansile duraplasty, and intracranial pressure monitor insertion is generally poor, with a mortality rate of 26.9% and a favorable outcome at 6 months in approximately 27.4% of patients, as shown in the RESCUE-ICP study 1. The patient underwent a right decompressive craniectomy, expansile duraplasty, and intracranial pressure monitor insertion as an emergency procedure. This surgical intervention is typically performed for severe traumatic brain injury, large ischemic stroke, or other conditions causing dangerous brain swelling and increased intracranial pressure. The decompressive craniectomy involves removing a portion of the skull to allow the swollen brain to expand outward, relieving pressure. The expansile duraplasty refers to enlarging the dura mater (the tough outer membrane covering the brain) with a graft material to accommodate the swelling. An intracranial pressure monitor was also inserted to continuously measure pressure within the skull, allowing medical staff to detect dangerous increases and adjust treatment accordingly.
Post-Operative Care
Following this procedure, the patient will require:
- Intensive care monitoring
- Management of intracranial pressure
- Prevention of complications like infection or seizures
- Eventually, a cranioplasty procedure to replace the removed skull portion once brain swelling resolves, typically after 1-3 months The use of intracranial pressure monitoring has become an integral part of the management of severe traumatic brain injury patients, although its benefit on patient outcome has not been clearly demonstrated 1. The incidence of high intracranial pressure varies between 17 and 88%, and an intracranial pressure of 20-40 mmHg is associated with a higher risk of mortality and poor neurological outcome 1.
Sedation and Analgesia
The maintenance and cessation of sedation and analgesia in patients with severe traumatic brain injury should follow the guidelines for non-brain injured patients, apart from the treatment of intracranial hypertension and convulsive status epilepticus 1. The daily interruption of sedation may be deleterious to cerebral hemodynamics in signs of high intracranial pressure on brain CT scan, and the implementation of protocols to manage sedation and analgesia may provide benefits 1.
Outcome
The prognosis for these patients is generally poor, with a significant risk of mortality and poor neurological outcome. However, the RESCUE-ICP study showed that decompressive craniectomy can reduce mortality rates and improve outcomes in patients with refractory intracranial hypertension 1. The patient's outcome will depend on various factors, including the severity of the initial injury, the effectiveness of the surgical intervention, and the quality of post-operative care.
From the Research
Prognosis After Emergency Decompressive Craniectomy
The prognosis for a patient who underwent an emergency right decompressive craniectomy, expansile duraplasty, and intracranial pressure (ICP) monitor insertion can be understood by considering the following points:
- Mortality and Disability: Decompressive craniectomy (DC) is a life-saving procedure that results in lower mortality but also higher rates of severe disability 2.
- Complications: The incidence of complications following DC is high, with at least one complication occurring in 74% of patients 2. However, there is no significant impact of complications on outcome.
- ICP Reduction: DC is an effective ICP-lowering procedure, with moderate quality evidence showing that it is superior to standard care for reducing ICP within 48 hours 3.
- Neurological Outcome: The effects of DC on long-term neurological outcome are controversial, with some studies showing a clear reduction in risk of death or vegetative state, while others show little difference between DC and standard care 3.
- ICP Monitoring: ICP monitoring appears useful in guiding therapy after primary DC, with a statistically significant relationship between mean post-decompression ICP and Glasgow Outcome Scale (GOS) scores 4.
Key Factors Influencing Prognosis
Some key factors that influence the prognosis after DC include:
- Trauma: Trauma is a risk factor for complications after DC 2.
- Coagulopathy: Coagulopathy is also a risk factor for complications after DC 2.
- Primary DC: Primary DC is associated with a higher risk of complications compared to secondary DC 2.
- ICP/CPP: The relationship between ICP/cerebral perfusion pressure (CPP) and neurological outcome is significant, with higher ICP and lower CPP associated with unfavorable outcomes 4.
