Post-Traumatic Stress Disorder (PTSD)

What is PTSD?

Post-traumatic stress disorder is a mental health condition caused by a trauma. The trauma can be a one-time thing (such as being victim of a crime) or long-term (such as living in a war zone or through a natural disaster). No one knows why some people bounce back after a trauma while others develop PTSD or why some people experience PTSD symptoms within weeks of the trauma and others may only start having symptoms years later.

Patients who are treated for sepsis in an ICU undergo several traumas. They have a serious illness, potentially bringing them to the brink of dying. Their body is subjected to numerous medical interventions. They are often in severe pain, and they feel scared and helpless. Add to this being in the busy ICU environment 24 hours a day, and the situation is primed for a psychological reaction like PTSD.

Some of the symptoms of PTSD include:

  • Having intrusive memories
  • Reliving events
  • Having upsetting dreams or nightmares about the event
  • Avoiding anything that may remind you of your experience
  • Feelings of hopelessness, depression, and anxiety
  • Being easily startled
  • Trouble sleeping or concentrating
  • Sleeping too much
  • Getting irrationally angry or aggressive

The symptoms may come and go, or they may linger.

Family members may be depressed too

When a loved one is critically ill, family members often feel helpless. They may relive events, wondering if they could have done something different, even once the emergency is over. They may feel guilt over past issues or fear for the future. Their experience is very different from that of the patient, but they, too, have gone through a stressful time and this may go unrecognized, and may lead to depression or anxiety.

Recognizing the problem

Recognizing the problem is the first step towards helping sepsis survivors and their loved ones to deal with lasting psychological issues. People who experience signs of PTSD, depression, or anxiety should acknowledge this and seek help from their doctor or qualified mental healthcare practitioner. These conditions can often be successfully managed through a combination of self-care, counseling or medications.

PTSD can be part of post-sepsis syndrome, or PSS. Learn more here.
