Recognizing oesophageal intubation: successful use of the oesophageal detector device combined with a disposable end-tidal carbon dioxide detectorBothma, Pieter Adriaan 17 August 2016 (has links)
A dissertation to the Faculty of Medicine, University of the
Witwatersrand, Johannesburg, in fulfilment of the requirements for the
degree of Master of Medicine (in the branch of Anaesthesia).
Johannesburg 1994. / Unrecognized oesophageal intubation leads to death or severe disability.
Even careful, well trained anaesthetists may be unable to differentiate
tracheal from oesophageal intubation by the commonly employed methods.
End-tidal carbon dioxide measurement has been found to be a reliable test
of tracheal intubation. The availability of a small disposable end-tidal carbon
dioxide detector, the Easy cap makes this facility universally available. The
oesophageal detector device is a small mechanical device used to recognize
oesophageal intubation. By combining two reliable devices working on
completely different principles the risk of false negative or false positive
results are virtually eliminated. The potential defects of each device are
covered by the other.
The purpose of this study was to evaluate the combined use of the
oesophageal detector device and the Easy cap by a blinded observer to
differentiate the endotracheal tube from an oesophageal tube in sixty
patients. These two tests were found to be very reliable, easy, rapid and
cheap - ideal for use in theatre, casualty departments and in the field. The
advantages and disadvantages of these devices are discussed and the relevant
literature is reviewed.

A review of indications for endotracheal intubation in a private emergency centre in PretoriaGroenewald, Anita 12 July 2012 (has links)
M.Sc. (Med.), Faculty of Health Sciences, University of the Witwatersrand, 2011 / There is no clear list of indications for endotracheal intubation in the emergency
centre. Current indications are derived from studies done in other disciplines, such as
anaesthesiology (1, 2). The emergency centre is unique due to the presence of
clinically undifferentiated patients as well as the urgency accompanying the
management of critically ill or injured patients.
A consensus statement for South African emergency centres was developed using a
modified Delphi approach. The statement makes recommendations for a list of
indications for endotracheal intubation in the emergency centre. This retrospective
record review looks at indications used for endotracheal intubation in a private
emergency centre during 2006. These indications were then measured against the
consensus document derived from indications suggested by experts.
The study evaluated 183 critically ill or injured patients during the study period of
which 56 were intubated. Of all the critically ill or injured patients, only three were not
intubated that should have been, according to the consensus document. The study
found that the emergency doctors in the specific emergency centre used similar
indications to intubate as suggested by the consensus document.

Retrospective Review of the Short-Term Outcomes of Tracheal resection for Laryngotracheal stenosis at Chris Hani Baragwanath hospitalMakaulule, Ratshili Prince January 2019 (has links)
A research report submitted to the Faculty of Health Sciences, University of the
Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of
Master of Medicine in Otorhinolaryngology.”
Johannesburg, 2019 / INTRODUCTION:
Laryngotracheal stenosis is rare but has become a well-recognized pathological
otorhinolaryngological condition. It develops when scar tissue forms in the trachea and
larynx. Laryngotracheal stenosis can cause significant morbidity and the management of it
is often complex. Tracheal resection with end-to-end anastomosis is a well-recognized
surgical procedure performed for treatment of larygotracheal stenosis and has been
shown to have great success.
AIM:
To review the short-term outcomes of tracheal resection for
larygotracheal stenosis at the Chris Hani Baragwanath Academic
Hospital Otorhinolaryngology Department.
METHOD:
This was a retrospective study, reviewing 24 patients with larygotracheal stenosis who
underwent segmental tracheal resection with end-to-end anastomosis at the Chris Hani
Baragwanath Academic Hospital, performed between 2005 and 2015.
RESULTS:
The study included 24 patients with ages ranging from 18 to 64 years. There were 15
(62.5%) males and 9 (37.5%) females. The causes of larygotracheal stenosis were
prolonged intubation in 22 (91.7%) and inhalation burns in 2 (8.3%) patients. Eleven
patients (45.8%) had postoperative complications, of which 4 (36.4%) were minor
complications and 7 (63.6%) were major complications. The outcomes of surgery were
excellent in 13 (54.2%), satisfactory in 8 (33.3%) and unsatisfactory in 3 (12.5%).
CONCLUSIONS:
Prolonged intubation was found to be the most common cause of larygotracheal stenosis.
Tracheal resection for larygotracheal stenosis has been shown to have satisfactory to
excellent short-term outcomes in terms of successful decannulation, voice quality, and
low morbidity. In our study, the surgery was successful in 21 (87%) patients, which is
comparable to success rates shown in the literature. Preoperative tracheostomy and
higher degree of stenosis Meyer Cotton (III and IV) were associated with high postoperative complications. Irrespective of the cause, tracheal resection is a good surgical option, for the treatment of patients with severe stenosis and those who have failed treatment from other alternative surgeries. / E.K. 2019
