Suction tube with pressure regulation: technical note

Negative pressure suction technique for bone cement introduction into the delivery syringe. A technical note.

The authors present in this brief note a technique to facilitate the introduction of high viscosity bone cement into a cement syringe for retrograde high pressure cementing during total hip or revision knee arthroplasty. The nozzle part of the syringe is connected to the suction device used intra-operatively, to achieve a negative pressure in the syringe. Introduction of the cement into the syr...

Parotid Duct Repair with Intubation Tube: Technical Note

The parotid duct can be damaged in traumatic injuries and surgical interventions. Early diagnosis and treatment of a duct injury is of great importance because complications such as sialocele and salivary gland fistula may develop if the duct is not surgically repaired. We think the cuff of an intubation tube is an ideal material in parotid duct repair, because of its technical characteristics,...

Kinetics of Benzyl Chloride Production in a Bench Reactor Under Pressure with Stirrer (TECHNICAL NOTE)

Benzyl chloride is economically one of the most important starting materials for a large number of industrial syntheses. Far too much money is now spent to buy and import this valuable product. The production of benzyl chloride has been recognized as one of our national projects and budgeted by the National Iranian Petrochemical Organization in order to economize on the country’s foreign exchan...

Cricoid pressure prevents placement of the laryngeal tube and laryngeal tube-suction II.

BACKGROUND The laryngeal tube has a potential role in patients with a difficult airway, but cricoid pressure is required if the patient is at risk of aspiration. The effect of cricoid pressure on insertion of these devices is unknown. METHODS In a randomized cross-over study, the laryngeal tube (25 patients) or the laryngeal tube-suction II (15 patients) was inserted with cricoid pressure app...
