Post Intensive Care Syndrome – Understanding the Aftermath

Post Intensive Care Syndrome (PICS) is a set of new or worsened health problems that can occur after staying in an Intensive Care Unit (ICU). PICS can affect a patient physically, mentally, or cognitively and its symptoms can persist long after the patient has been discharged from the ICU.

The common symptoms and effects of PICS include:

• Cognitive Impairment: This can include problems with memory, attention, mental processing speed or problem-solving.
• Physical Impairment: A patient may face difficulties in physical activities such as difficulties in walking, muscle weakness, fatigue, and poor balance.
• Mental Health Problems: One might experience anxiety, depression or post-traumatic stress disorder (PTSD) after a ward in the ICU.

Significance of Critical Care Pharmacology in Intensive Care Nursing

Intensive care nursing requires precise attention to numerous medical details, among which pharmacology stands as a potent pillar. Critical Care Pharmacology is a branch of pharmacology that deals with the drug therapy of patients in a critical condition.

Critical Care Pharmacology is essential due to several reasons:

• Complex Medication Regimens: Patients in the ICU generally require a complex and often changing regimen of medications. Nurses need to understand what each medication does, when it is to be administered, and what side effects to watch out for.
• Pharmacokinetics and Pharmacodynamics: ICU patients often have altered metabolism, which can impact drug absorption, distribution, metabolism, and elimination. Understanding these changes is vital to adjust doses and avoid toxicity.
• Interactions: ICU patients are typically on multiple drugs, which raises the risk of drug interactions. Comprehending potential interactions can prevent harmful side effects.

The Intensive Care Nurse - Roles and Duties

The specialisation of the intensive care nurse (ICN) embodies highly skilled and trained nursing professionals prepared to provide care for the most critically ill or injured patients. Their roles and duties are plentiful and carry tremendous importance in patient care.

Key roles and duties of an Intensive Care Nurse include:

• Direct Patient Care: An ICN provides comprehensive care to patients, from basic needs, such as hygiene and comfort, to complex needs, such as ventilator care and titrating drips.
• Monitoring Vital Signs: ICNs continuously monitor the patient's vitals and are trained to identify and promptly respond to any sign of deterioration.
• Collaborative Care: ICNs collaborate with a team of healthcare professionals, including physicians, pharmacists, and therapists, to plan and implement patient care.
