Fifty three Medical ICU patients underwent tracheostomy procedure through percutaneous dilatational
technique using both Grigg's and Ciaglia's methods.
This non-randomised retrospective study compares percutaneous dilatational
tracheostomy with standard operative tracheostomy performed in intensive care units.
Ilhan Ozdemir State Hospital, Giresun, Turkey, between October 2013 and February 2014, and comprised patients greater than 18 years of age who were dependent on mechanical ventilation for an extended duration and were scheduled to undergo percutaneous dilatational
tracheostomy with Griggs technique.
The spherical stretch strain is the bond's normal strain owing to spherical dilatational
deformation, the deviatoric stretch strain is the bond's normal strain owing to the deviatoric deformation and the shear strain is the bond's tangential strain due to the whole deformation.
6] So-called noncompliant balloons were exclusively used in our study; they are characterised by the fact that they only change their diameter minimally upon dilatational
pressure and therefore minimise the risk of overexpansion.
Clinical experience with 100 cases of percutaneous dilatational
tracheostomy with and without bronchoscopic guidance.
These holes, called dilatational
bands, function as a natural defense mechanism, and help to prevent further damage to the surrounding bone.
Endoscopic percutaneous dilatational
tracheotomy: A prospective evaluation of 500 consecutive cases.
The hole drilled through a number of steeply dipping, northerly trending gold bearing pyrite veins without intersecting any bonanza grades which are associated with vertical dilatational
zones and occur where these veins intersect with a prominent easterly trending fracture set, such as that intersected in NEV022 (2m at 98.
Bedside percutaneous dilatational
tracheostomies were done in three (20%) cases.
tracheostomy (PDT) is a common bedside procedure in critical care for patients requiring prolonged mechanical ventilation, having shown reduced complications compared to surgical tracheostomy (1).

tracheostomy versus surgical tracheostomy in critically ill patients: a systematic review and meta-analysis Critical Care 10 R55
Our study had insufficient data to attribute the increased incidence of tracheal stenosis to the introduction of the percutaneous dilatational
tracheostomy technique that has gained recent popularity.
On the other hand, for shear AE, both compressional and dilatational
P-wave first motions are detected.
The researchers investigated the physical properties of foams--overrun, yield stress, volume, surface tension and dilatational
elasticity at air-water interfaces.
