Particle tracking microrheology is used to study the effect of a constant applied shear during gelation of aqueous gellan gum with a monovalent salt. Shear modifies the gellan gum hydrogel microstructure and the bulk rheological properties of the system, depending on whether shear is applied during gelation or afterwards. The microstructure determines the linear elastic response of the gel, as ...

A randomised cross-over study was performed in 34 patients with no evidence of airway difficulties, following induction of general anaesthesia, to compare the efficacy of the Levitan FPS scope (LFPS) and the single-use bougie for tracheal intubation during simulated grade IIIa laryngoscopy. Success rates for intratracheal placement of the device, and the time required for insertion and tracheal...

A patient developed sepsis syndrome with shock 7 h after an anaesthetic for a shoulder replacement. Tracheal intubation had been difficult and required the use of a stylet and gum-elastic bougies. A gastrografin swallow subsequently demonstrated an oesophageal perforation and mediastinitis was diagnosed at surgical exploration. She survived after a prolonged period of intensive care treatment.

Purpose: To analyze the outcomes of patients in whom we performed a SG depending on the calibrating bougie. Methods: Retrospective review of patients who underwent SG. Baseline characteristics were analyzed, and outcomes compared between groups. In order to identify the contribution of each predictor in the %EWL, a linear regression univariate and multivariate model was constructed. Results: 16...

To the Editor: The tracheal tube introducer (bougie) is widely used to facilitate difficult intubation. However, single-use introducers, compared to reusable ones, appear to be more traumatic [1-3]. A 61-year-old woman with esophageal reflux and no predictive signs of difficult intubation received rapidsequence induction with application of cricoid pressure. Direct laryngoscopy revealed a Corma...

INTRODUCTION We compared intubating with a preloaded bougie (PB) against standard bougie technique in terms of success rates, time to successful intubation and provider preference on a cadaveric airway model. METHODS In this prospective, crossover study, healthcare providers intubated a cadaver using the PB technique and the standard bougie technique. Participants were randomly assigned to st...

An oscillatory capillary rheometer was used to investigate the effects of NaCl, KCl, and CaCl2 on visco-elastic properties of xanthan and locust bean gum (LBG) blends in dilute solution. Gums were evaluated for intrinsic viscosity and elastic component. Molecular conformation of the xanthan–LBG complex was assessed by the power-law and Huggins equations. Addition of any of the three salts reduc...

BACKGROUND In this study a new instrument and technique is described for the endoscopic treatment of complete posterior urethral strictures, which may result in serious complications and sometimes require troublesome treatments. METHODS Three patients with complete posterior urethral obstruction were treated endoscopically with the guidance of a new instrument: Evrim Bougie. Evrim Bougie look...
