A tracheostomy is an opening (made by an incision) through the neck into the trachea (windpipe). A tracheostomy opens the airway and aids breathing.

A tracheostomy may be done in an emergency, at the patient’s bedside or in an operating room. Anesthesia (pain relief medication) may be used before the procedure. Depending on the person’s condition, the tracheostomy may be temporary or permanent.

When is a tracheostomy considered❓

A tracheostomy may be performed for the following conditions:

▪️Obstruction of the mouth or throat
▪️Breathing difficulty caused by edema (swelling), injury or pulmonary (lung) conditions
▪️Airway reconstruction following tracheal or laryngeal surgery
▪️Airway protection from secretions or food because of swallowing problems
▪️Airway protection after head and neck surgery
▪️Long-term need for ventilator (breathing machine) support

【Molecular Characterization of Bacterial Community Composition in the Rhizosphere of Invasive Plant Species Amur Honeysuckle (Lonicera maackii) in an Urban Wetland Forest】
#论文#

#土壤微生物# #植物# #森林# #生态系统#

Soil microbes, through their positive or negative impacts on individual plants, can be key determinants of plant community diversity and composition. This research investigates the effects of the growth of invasive plant Amur Honeysuckle (Lonicera maackii) on the rhizosphere bacterial community composition, and diversity in an urban wetland forest ecosystem.

【有趣#俚语# 】Lemon law≠柠檬の法律上回书说到，"Lemon"除了水果柠檬之外，还有没用之物，蹩脚货的意思。所以，"Lemon law"是不是就是：伪劣商品赔还法‍⚖️
英英释义：A law requiring an automobile manufacturer or dealer to replace, repair, or refund the cost of an automobile that proves to be defective after purchase.

eg.Congress passed much tighter lemon laws this summer.
今年夏天，国会通过了更为严格的伪劣商品赔还法。
