'Post perfusion syndrome' was a term historically associated to cardiac surgery in view of
the transient neuro-cognitive deficits attributed to cardio pulmonary bypass pump. During
their recovery period, a significant number of patients experience delirium, a clinical
syndrome of acute onset and fluctuant course.Though these deficits are often known to be
transient without any permanent physical or neurological impairment, the experience can
still psycho-socially affect these patients for a longer length of time even after
discharge. The presence of delirium puts excessive, undesired strain on the patient, their
families, health care providers and hospital resources.
PTSS is an anxiety disorder caused by very stressful, frightening or distressing events. It
is known to either develop immediately after the disturbing event or weeks and months later.
The actual symptoms can be varied but are categorized in three sections: i.e.:
re-experiencing, avoidance and emotional numbing and hyperarousal (feeling 'on edge').
A problem that has such an impact on any patient is worth investigating and understood
better. Being in such a unique professional position, as a Clinical nurse practitioner, the
investigator is ideally placed to conduct this study. In this study, the researcher will be
focusing on the pre-operative risk factors in developing delirium, actual incidence of
delirium and follow the patients post operatively to evaluate the after effects of delirium
in the form of PTSS.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | What factors during the peri-operative period in patients with delirium are associated with higher incidence of post traumatic stress symptoms? | 6 weeks and 3 months following delirium post cardiac surgery | No | |
Secondary | What are the peri-operative factors that are associated with change in PTSS score from 6 weeks to 3 months. | 6-12 weeks | No | |
Secondary | What are the pre operative features that predict post operative delirium | The pre operative data collected will form an entry baseline for the study. But this will also aid in identifying common factors that are noted in patients who develop post operative delirium. | 5 days | No |
