Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...

We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).

FAQs
During PEG placement, endoscopic transillumination helps clinicians identify a suitable gastric site through the abdominal wall before puncture. A guidewire then provides a defined path for advancing the tube, while internal and external bumpers hold it in position. Together, these components connect visual confirmation, controlled access, and mechanical stabilization during placement.
PEG becomes relevant when oral intake is inadequate, yet the gastrointestinal tract remains usable for enteral nutrition. Common clinical contexts include swallowing impairment associated with neurologic disease or cancer treatment. Compared with repeated nasogastric tube placement, it offers a longer-term route for delivering nutrition when ongoing support is expected.
The two bumpers help maintain the feeding tube across the abdominal wall and keep its position relative to the stomach. Their stabilizing role is clinically important because displacement can compromise feeding access and contribute to leakage. Monitoring remains necessary to identify tube movement or other problems early, including infection and bleeding.
Clinicians first use an endoscope to examine the stomach and transilluminate it through the abdominal wall. They then puncture the selected area, pass a guidewire, and use that guidewire to position the feeding tube. Internal and external bumpers secure the tube after placement, completing the access route for enteral nutrition.
Post-placement monitoring should focus on infection, bleeding, leakage, and tube displacement, all of which are identified complications of PEG. These problems can affect local healing, tube stability, or delivery of nutrition. Careful patient selection and continued observation are therefore important parts of using the procedure safely in medical practice.
In neurologic disease or during cancer treatment, swallowing impairment may prevent adequate oral intake even when gastrointestinal function remains usable. PEG provides a route for longer-term enteral nutrition in these circumstances. Its use can improve nutritional delivery while avoiding the need for repeated placement of a nasogastric tube.
