Retrospective analysis and pre-clinical studies suggest that local anesthetics have anti-tumoral effects. However, the association between cancer recurrence and the use of local anesthesia is inconclusive and most reports are based on single local anesthetic results. ⋯ Our work demonstrates the differential effects and proposes the mechanisms of local anesthetics on esophageal carcinoma cell migration, growth, survival and chemosensitivity.

The anesthesia of patients with large mediastinal mass is at high-risk. Avoidance of general anesthesia in these patients is the safest option, if this is unavoidable, maintenance of spontaneous ventilation is the next safest technique. In these types of patients, it is not applicable to use double-lumen tube (DLT) to achieve one-lung ventilation (OLV) because the DLT has a larger diameter and is more rigid than single-lumen tube (SLT), so the mass may rupture and bleed during intubation. Even using a bronchial blocker, a small size of SLT is required for once the trachea collapses the SLT can pass through the narrowest part of trachea. However, it is difficult to control the fiberoptic bronchoscopy (FOB) and the bronchial blocker simultaneously within the lumen of a small size SLT with traditional intubation methods. ⋯ Extraluminal use of Uniblocker and maintenance of spontaneous ventilation during intubation may be an alternative to traditional methods of lung isolation in such patients with a large mediastinal mass.

The classic formula has been used to estimate the depth of tracheal tube intubation in children for decades. However, it is unclear whether this formula is applicable when the head and neck position changes intraoperatively. ⋯ Change in head position can influence the depth of tracheal tube intubation. Therefore, the estimated depth should be corrected according to the surgical head position.

The use of Spinal Cord Stimulation (SCS) system to treat medically refractory neuropathic pain is increasing. Severe neuropathic pain can be found in giant chest wall arteriovenous malformations (AVMs), exceedingly rare and debilitating abnormalities, rarely reported during pregnancy. ⋯ The use of lumbar US to find a safe site for a lumbar puncture in presence of SCS system in a patient affected by painful thoracic AVM makes this case a particularly unique operative challenge and offers a new possible use of ultrasound to detect a safe space in patients with SCS implant.
