AI Article Synopsis
- A modified tracheostomy approach was created for respiratory studies in sheep to avoid severe tracheal stenosis seen in canine procedures.
- The surgical method involved making a slit in the trachea and sewing the mucosa to the skin, which successfully prevented significant stenosis in 19 out of 19 sheep after evaluation.
- In contrast, a traditional method that removed part of the tracheal rings resulted in severe stenosis in 5 out of 20 sheep.
Article Abstract
A modified tracheostomy was designed for respiratory function studies in sheep. Our primary objective was to prevent development of severe tracheal stenosis, which was observed with procedures designed for canine tracheostomy. Surgery consisted of an intercartilaginous tracheal slit, with apposition of tracheal mucosa to skin. This procedure produced no significant stenosis at postmortem evaluation in 19 sheep. In contrast, 5 of 20 sheep with excision of the ventral 1/3 of the third and fourth tracheal rings, had severe tracheal stenosis.

Cervical plexus block (CPB), like other types of regional anesthesia, represents an alternative anesthetic technique in those cases where the performance of general anesthesia (GA) carries an increased risk both for the patient and the outcome of the operative treatment. It has traditionally been used for years in carotid surgery as an alternative to GA, especially due to the possibility of superior monitoring - the awake patient. However, its effectiveness has been proven in other types of neck surgery, primarily in thyroid surgery, neck dissections, tracheostomy, central venous catheter insertion, clavicle surgery, etc.

BACKGROUND Ureaplasma urealyticum (UU) is a common microorganism that has been associated with a variety of obstetric and neonatal complications, such as infertility, stillbirth, histologic chorioamnionitis, neonatal sepsis, respiratory infections, and central nervous system infections. However, it is rare for it to cause severe neonatal asphyxia. This rarity is the focus of our case report, which aims to highlight the potential severity of UU infections in newborns.
