Evaluation of Modified Knot Technics for Retrograde Intubation

Retrograde tracheal intubation.

Summary Successful management of difficult tracheal intubation by retrograde intubation has been reported for almost 50 years and can be used whether or not it is anticipated. There are numerous reports of variations to the basic technique to enhance reproducibility of this guided blind procedure. A review and analysis of the equipment and techniques provides a better understanding of this effe...

A modified technique of retrograde intubation dacryocystorhinostomy for proximal canalicular obstruction

PURPOSE To describe a modification of the retrograde intubation dacryocystorhinostomy (DCR) in patients with proximal canalicular obstruction. MATERIALS AND METHODS Interventional case report of a 43-year-old female with a nine-month history of left epiphora following a road traffic accident involving the proximal lower canaliculus. An external DCR approach was performed. Following the creati...

Retrograde Wire Intubation in Airway Management

Retrograde intubation using the subcricoid region.

The applied anatomy of the cricothyroid and cricotracheal region of the neck and a retrograde method of tracheal intubation using the subcricoid region are described. This approach has several advantages, including absence of bleeding complications, as there are no major blood vessels on the cricotracheal membrane, and reduction in the possible development of subglottic oedema and stenosis.

An evaluation of turbidimetric technics for estimation of plasma fibrinogen.

Studies on precipitation and turbidimetric methods for fibrinogen determination employing Na2SO3, Na2SO4, (NH4) 2S04 and a mixture of phosphate salts are presented. Optimal reaction conditions for these technics have been verified. The amounts of plasma fibrinogen precipitated by the sulfite and phosphate methods are in closer agreement than either are with values obtained by the (NH4)2S04 and ...
