Ehlers-Danlos syndromes (EDS) are a set of heritable heterogenous connective tissue disorders characterized by defects in collagen synthesis, affecting skin, ligaments, joints, blood vessels and other organs. EDS patients often have vascular fragility syndromes with arterial aneurysms and dissections. Patients also have kyphoscoliosis and due to the underlying connective tissue abnormalities, these patients often present for orthopedic surgery. Overall, there is very little evidence-based knowledge for the management of EDS. Much of the literature is based upon expert opinion.
Anesthetic implications
Preoperative optimization
- Preoperative evaluation should focus on bleeding history, cervical/TMJ hypermobility, skin fragility, scoliosis, signs of mitral/aortic insufficiency
- Vascular instability may cause major vessel dilation and cause aortic or mitral insufficiency
Intraoperative management
Monitoring:
- Arterial lines run the risk of vascular wall dissection. Consider ultrasound-guided arterial line placements
- EDS patients can often demonstrate orthostatic tachycardia syndrome (POTS)
Positioning:
- Eyes should be protected to prevent retinal detachment and globe rupture
- Careful padding of extremities
Skin Fragility
- Minor forces can result in skin injuries such as tape, stickers, and other monitors that attach to the patient
- Bruising and hematoma formation occurs with repetitive non-invasive BP monitoring
- Special attention to removing tape from eyes and skin
- Discuss the risk/benefits of using a tourniquet in these patients with surgical team
Airway Management:
- Care should be taken for TMJ joint laxity during laryngoscopy
- EDS patients may present with occipitalatlantoaxial instability causing TMJ joint dislocation
Postoperative management
- Early mobilization is helpful to prevent muscle loss
- Inspect surgical sites for hematomas or bleeding
- Patients with POTS should be monitored early after surgery for bleeding and cardiovascular instability
- Treat PONV aggressively to avoid esophageal rupture from violent vomiting
- EDS patients can have pneumothorax after positive pressure ventilation
- EDS patients with epidurals have greater risk for PDPH and epidural hematoma formation
Obstetric Considerations
- EDS patients are considered high-risk and should have maternal-fetal-medicine specialist consultations
- Prone to premature rupture of membranes, preterm labor, and uterine/vascular ruptures[1]
- Labor and delivery may progress very rapidly in the hypermobile form of EDS
- Patients may have significant kyphoscoliosis, making neuraxial anesthesia challenging although not contraindicated
- Use caution or avoid neuraxial approaches in patients with vascular EDS
- Remifentanil PCA may be a good alternative for these patients
- EDS patients have greater rates of post-dural puncture headaches because of underlying tissue fragility
- Some EDS patients have spontaneous dural ruptures causing PDPH-symptoms without iatrogenic insult to the dura

Pathophysiology
Mutations to genes that code for fibrillar collagen proteins in connective tissue
Their are six manor subtypes ranging phenotypically from very mild to life-threatening phenotypes.[2][3]
Signs and symptoms
- Joint hypermobility/instability
- kyphoscoliosis
- Skin fragility
- Aortic root dilitation causing aortic insufficiency
Diagnosis
Treatment
No treatments currently exist
Medication
Incidence is low and hence lacks randomized drug trials
Drug therapy will be protected under Orphan Drug development policies
Surgery
Prognosis
Epidemiology
