Overview
 This presentation mainly focuses on:
 Adult smoke inhalation injuries.
 For this purpose this presentation is exploring
 The background of the adult smoke inhalation in injuries covering underlying
cause behind smoke inhalation injuries and its importance for nursing practice
 Assessment methods for patient with smoke inhalation injuries
 Six priority interventions that should be taken to prevent adult smoke health
injuries and the rationale for it

Aims
 The purpose of this presentation is to develop an understanding about the:
 Prevalence and pathophysiology of adult smoke inhalation injuries
 Assessment methods that are adapted in clinical setting to detect smoking
inhalation injuries
 Possible interventions implemented to prevent the injury.

Background
Details about smoke inhalation injury
 Acute smoke inhalation injury is defined as
the damage which is caused by inhalation
of harmful gases.
 Smoke inhalation injuries are most
commonly found in all the flame burnt
people especially when there is a case of
facial burn.
 Acute smoke inhalation injury has a high
mortality rate
 Vulnerable populations like elderly people
and children are easily affected by acute
smoke inhalation injury
Causes:
 Smoke inhalation injury is a type
of injury that is caused during
major fire events due to
inhalation of steam,
superheated gases and
incomplete combustion products
 It leads to thermal burns in the
airways caused and it is the
leading cause of respiratory
problems and acute respiratory
distress syndrome (ARDS).
(Toon et al., 2010; Lawson-Smith et al., 2011)

Background
Pathophysiology:
 The severity of smoke inhalation injury is dependent on environment and host factors such as
source of injury, concentration of toxic gases, temperature and the response shown by the
individual to the injury.
 The pathophysiological steps involved in the injury includes formation of cast, decrease in
surfactant, increase in airway resistance and decreases pulmonary compliance
 Microvascular changes predicts development of such injuries
 Such changes result in lung injury and acute respiratory distress (Jones et al., 2017)
Epidemiology:
 It is a major public health problem as it results in about 1, 80, 000 deaths per year globally (World
Health Organization, 2019).
 In Australia, 5430 cases of burn injury has been reported in the year 2013-2014 (Australian
Institute of Health and Welfare, 2016).

Assessment
 The primary assessment methods for inhalation injury includes conducting direct
observation followed by diagnostic procedures such as bronchoscopy
 The primary assessment will focus on collecting data on history of injury, visual
cues of inhalation injury and detecting visible signs of airway or pulmonary
dysfunction (Tanizaki, 2015).
 In the unclear cases, the nurses assess patients with nasal fibreoptic endoscopy
after nasal decongestants and local anaesthetic spray (Cox et al.,2013).

Assessment
 Other tools that are critical in diagnosing inhalation injury includes
Fiberoptic bronchoscopy and bronchoscopic evaluation based on
inhalation injury.
 Bronchoscopy facilitates direct visualization of tissue damage and
scoring helps to identify the severity of injury (Tanizaki, 2015).
 A safe environment is necessary during assessment.
 In the case of airway emergency the patient's assessment is done by the
skilled staff with appropriate equipments.

Assessment
 When the patients are severe the following treatments are done:
 Airway management
 Treatment of specific intoxication
 Monitoring and investigations
 Experimental treatment
 Possible future treatments (Gupta et al., 2018)

Interventions
The six priority intervention necessary for emergency management of
patients with smoking inhalation injuries are as follows:
 Intubation: It is the most common emergency management step to
reduce respiratory distress for patients
 Mechanical ventilation: This involves providing assisted ventilation for
breathing support and reducing the risk of respiratory support for
patients.
 Bronchoscopy: Bronchoscopy involves endoscopic technique for
evaluating and monitoring the airways (Tanizaki, 2015).

INTERVENTIONS
 100% oxygen for CO poisoning: Hyperbaric oxygen is provided to
patients when suspected with CO poisoning. Patients are mechanically
ventilated using 100 O2.
 Hydroxocobalamin for cyanide toxicity: Hydrocobalamin, an injectable
form of Vitamin B12 is provided to patients in case of cyanide poisoning
(Jones et al., 2017).
 Medical adjuncts: Medicines like beta agonist and heparin is provided to
address pathophysiological changes in patient (Dries & Endorf, 2013).

Rationale
 Intubation: Intubation is required for patient when airway patency is in
danger because of the injury.
 Mechanical ventilation: It is needed to improve hypoxemia and increase
functional residual capacity.
 Bronchoscopy: The main rationale behind this is increasing pulmonary
hygiene and improving pulmonary secretions by removing accumulated
matters (Dries & Endorf, 2013).

Rationale
 100% oxygen for CO poisoning: The significance of this therapy is that it
can help to address loss of consciousness and conditions of increased
carboxyhemoglobin level.
 Hydroxocobalamin for cyanide toxicity: It is a first line treatment for
cyanide poisoning and it is an antidote that results in increased survival
rate for patients.
 Medical adjuncts: This treatment helps to address bronchoconstriction
and decreased arterial blood flow (Tanizaki, 2015).
