Clinical Trial Controlled Clinical Trial[The modification of injection pain and the incidence of thrombophlebitis following etomidate].
A prospective study with 161 patients was performed to investigate the effects of intravenous local anaesthetics on the pain of injection following etomidate injection. After placebo injection 56.6% of the patients reported on pain after etomidate, but only 29% after 20 mg lidocaine i.v. ⋯ The rate of postoperative thrombophlebitis was lowest in the group with combined lidocaine with venous congestives at 7.4%, in opposition to a rate of 18% in the remaining groups. In comparison to a second contralateral venous cannula without applied etomidate the venous sequelae did not increase significantly.

[Cricothyreotomy using the Quicktrach coniotomy instrument set].
Percutaneous cricothyroidotomy may be a lifesaving procedure for airway obstruction, which cannot be relieved by endotracheal intubation and can be performed with specially designed instruments. A new device, the "Quicktrach", was evaluated by an anatomical preparation, flow and resistance measurements, and puncture of the cricothyroid membrane in 55 corpses. The size of the parts of the instrument (needle, plastic cannula, depth gauge) in relation to the size of the larynx is adequate, thus there is little likelihood of perforation of the posterior wall of the larynx. ⋯ The "Quicktrach" is easy to apply even by inexperienced persons. The incidence of damage to the larynx (lesions including fractures of the thyroid, cricoid and 1. tracheal cartilage in 18%; soft tissue injury in 9%) is relatively high, however considering the live saving character of the procedure these numbers appear to be acceptable. Technical problems which occur with the use of the device are discussed and suggestions for improvement are made.
