Objective Nociceptive Assessment in Ventilated ICU Patients: A Feasibility Study Using Pupillometry and the Nociceptive Flexion Reflex
Published on: July 4, 2018
Summary
Intensive care survivors often recall distressing sensory and psychological experiences. These common memories highlight the need for improved patient comfort and care environments.
Area of Science:
- Critical Care Medicine
- Patient Experience Research
- Psychosomatic Medicine
Background:
- Intensive care units (ICUs) are vital for managing critically ill patients.
- The patient experience in ICUs is often characterized by numerous stressors.
- Understanding these stressors is crucial for holistic patient care.
Discussion:
- Patients frequently report adverse sensory stimuli, including pain, noise, and extreme temperatures.
- Psychological distress, such as fear, anxiety, and isolation, are prevalent memories.
- Basic physiological needs like thirst and hunger, alongside sleep deprivation, significantly impact patient recall.
Key Insights:
- A wide range of negative experiences, from physical discomfort to psychological distress, are common among ICU survivors.
- Sensory overload (noise, light) and deprivation (absence of daylight) are significant factors.
- Feelings of helplessness due to physical restraint and lack of information contribute to patient suffering.
Outlook:
- Future research should focus on mitigating these adverse experiences through environmental modifications and enhanced communication.
- Developing patient-centered care protocols can alleviate common stressors in the ICU.
- Improving the ICU environment is essential for better patient outcomes and recovery.

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

01:13Patient-centered Care
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
01:21Methods of Documentation III: PIE
Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:
01:27Ethical Issues
Nurses are essential in patient care, upholding the ethical principles of their profession and effectively navigating ethical dilemmas. Neglecting ethical issues can lead to inadequate patient care, compromised therapeutic relationships, and moral distress among healthcare workers.

01:23Acute Respiratory Failure-IV
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
01:26Acute Coronary Syndrome V: Nursing Management
Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
