Introduction Although rare during routine mediastinoscopy, CVAs can occur in patients who are not adequately monitored. Ventilation of both lungs through a single-lumen endotracheal tube is usually adequate. However, the majority of these patients are asymptomatic and the mass is discovered on routine chest X-ray.

This is secondary to prolonged compression of the innominate artery caused by the mediastinoscope, precipitating malperfusion to the head. The increased visual field, image magnification, and ability to use two instruments simultaneously make it a popular technique. The reported incidence of pneumothorax after mediastinoscopy is 0. Paralysis is required until end of procedure.

Invasive Blood Pressure Monitoring During Mediastinoscopy: Which Side Are You On?

I am happy to report there has not been one since they have taken over the department. Our surgical volume has grown over cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!

Additionally we have seen a reduction if requested preop lab tests. Sign In or Create an Account.

The less commonly performed anterior approach is through the second intercostal space, lateral to the sternal border; this is used to inspect the lower mediastinum. In particular, the pulse oximeter probe was placed on the left hand for oxygenation and hemodynamic monitoring.


Ideally, muscle relaxants should be avoided in patients with clinical features suggestive of myaesthenic syndrome. Patients should only be extubated after full recovery of reflexes and neuromuscular function; a short period of postoperative ventilation may be required. You must be logged in to post a comment. The mediastinum is rich in mefiastinoscopy nodes that are the site of localized inflammatory disease, primary lymphatic tumours or metastatic disease.

The middle mediastinum contains heart and pericardium, tracheal bifurcation and main bronchi, the lung hila, phrenic nerve, anesthseia, and lymph nodes. Perioperative cardiorespiratory complications in adults with mediastinal mass. Although rare during routine mediastinoscopy, CVAs can occur in patients who are not adequately monitored.

For Permissions, please email: The posterior mediastinum contains descending aorta, oesophagus, vagus nerve, the sympathetic chain, thoracic duct, azygos and hemiazygos veins, and paravertebral lymph nodes. These require selective lung collapse. Patients with myasthenia gravis are sensitive to non-depolarizing muscle relaxants and have a variable response to depolarizing agents. Other relative contraindications include severe tracheal deviation, cerebrovascular disease, severe cervical spine disease with limited neck extension, previous chest radiotherapy, and thoracic aortic aneurysm.

Intraoperatively, a right radial arterial catheter was placed for hemodynamic monitoring after the induction of general anesthesia and endotracheal intubation using standard American Society of Anesthesiologists monitors. The mediastinoscope is then inserted anterior to the aortic arch.

Mediastinoscopy (Guide)

Anesthesix reinforced tube is preferred to minimize the risk of the tube kinking during surgery. Of note, an arterial line was crucial in this speedy diagnosis, but the laterality of the invasive monitor—right-sided—proved decisive.

In addition to routine haematology, biochemistry, and ECG, preoperative investigations should include chest X-ray, and CT scan aimed at evaluating the location of the tumour, its relation to adjoining structures, and the degree of tracheal compression. If the initial intubation was not difficult, this can be achieved by passing a left-sided double lumen tube while the bleeding is being controlled by digital compression.


Hence, maintenance of spontaneous ventilation is critical to avoid precipitating complete obstruction in these patients.

With a long-standing mass, fibreoptic endoscopy should be performed prior to extubation to rule out tracheomalacia. Some may argue that a pulse oximeter on the right hand can achieve the same goal of detecting mediastinosopy, as a poorly perfused hand due to innominate artery compression can cause a decreased pulse oximeter reading.

Tracheobronchial obstruction can potentially worsen with induction of general anaesthesia and intermittent positive pressure ventilation IPPV. Flow—volume curves should be obtained in the upright and supine position to evaluate functional impairment and ascertain the presence of obstruction. If the patient is asymptomatic, preoxygenation followed by intravenous induction of anaesthesia can be performed. Consider A-line based on health of patient. Hence, a right radial arterial catheter may be the best monitor for the timely detection of innominate artery compression, especially in older patients with atherosclerosis and possible poor circle of Willis collateral circulation.

Regular paracetamol and NSAIDs if not contraindicated could be prescribed as part of multimodal analgesia. Close mobile search navigation Article navigation.

The surgeon was notified immediately and the scope repositioned, relieving pressure of the right-sided vessel and restoring appropriate flow to the right upper extremity and right cerebral hemisphere.
