Low-positive pressure ventilation improves non-hypoxaemic apnoea tolerance during ear, nose and throat pan-endoscopy: A randomised controlled trial.

Background: It has been suggested that oxygenation using pressure support ventilation (PSV) before general anaesthesia can reduce the duration of non-hypoxaemic apnoea.

Objective: The objective was to determine whether or not pre-oxygenation with PSV increases the duration of non-hypoxaemic apnoea in non-obese patients during pan-endoscopy.

Design: A randomised, controlled trial.

Ultrasound-guided percutaneous tracheostomy in critically ill obese patients.

Introduction: The purpose of this study was to evaluate the feasibility of ultrasound (US)-guided percutaneous tracheostomy (PCT) and the incidence of complications in critically ill, obese patients.

Methods: Fifty consecutive patients were included in a prospective study in two surgical and critical care medicine departments. Obesity was defined as a body mass index (BMI) of at least 30 kg/m².

[Management of the papillary microcarcinoma of the thyroid gland].

Objectives: To study the management and treatment of papillary microcarcinoma of the thyroid.

Material And Methods: Retrospective study of 57 patients operated on their thyroid gland between 1995 and 2004. All patients had a frozen section of the specimen.

Subjective voice assessment after thyroid surgery: a prospective study of 395 patients.

Background: Total thyroidectomy has become a routine surgical procedure. However, postoperative complications are not rare and can lead to voice disorders.

Aim: To study voice quality after total thyroidectomy.
