Palliative Care: The
need in T&T
• Three hospitals: EWMSC, POSGH, SFGH
• several doctors did not fully understand the
meaning of the word “palliative” as the majority
thought this exclusively applied to cancer patients
only
• Example: “You mean that you’re looking for cancer
patients?”
• It appeared that the nurses were better able to
identify these patients and showed a better
understanding when asked further about the
patient’s condition
• Unable to quantify these observations at present

What is dyspnoea?
• Dyspnoea may be defined as the
uncomfortable awareness of
breathing
• The feeling / sensation that you
cannot get enough air into your
lungs
• Shortness of breath
• It is subjective
• It is a symptom
What dyspnoea is not
• Rapid breathing (tachynoea)
• Deep breathing (hyperpnoea)
• Though all of the above may be
associated with dypnoea

Dyspnoea Trajectories
• Dyspnea is the most distressing symptom
experienced by critically ill patients at risk for
dying
• New data suggests different stages of onset of
dyspnoea prior to death
• Patients with noncancer diagnoses, particularly
chronic obstructive pulmonary disease, experience
severe dyspnoea for months before death
• whereas patients with cancer even without
apparent cardiorespiratory disease have an
escalation of dyspnoea near death
• The sickest patients and those who are cognitively
impaired or unconscious are not represented
because self-report measures are used

Cancer patients on
Chemotherapy: Symptoms
Clusters
• One Japanese Study of 462 patients during
follow-up found 4 major clusters of
symptoms:
1) psychosocial issues (insomnia,
psychological distress, decision-making
support);
2) nutrition-gastrointestinal issues (oral
problems, appetite loss, nausea);
3) fatigue; and
4) pain, dyspnea, and numbness.

Advanced Cancer and
Dyspnoea
• 135 patients with end stage
lung cancer
• Pain Clinic (M.D. Anderson Cancer Centre, Texas)
• Moderate to severe dyspnoea in
55%
• Severity of dyspnoea related to
• lung involvement (P = 0.0016) and
• anxiety (P = 0.0027)
Bruera et al. J Pain Symptom Manage. 2000
The Take Home
Message
• Dyspnoea is a disabling and
subjective sensation of inability to
breathe
• Dyspnoea is common in all end stage
diseases
• Dyspnoea may cluster with other
symptoms such as pain and
numbness
• In cancer patients lung involvement
and anxiety are related to dyspnoea
