The pupillary dilation reflex to a nociceptive stimulus as a tool for analgesia management: A diagnostic study.

Background: More than 70% of patients demonstrate pain after endotracheal aspiration. Tools are needed to objectify the need for analgesia in non-communicative critically ill patients.

Objective: The objective of this study was to identify the lowest intensity electrical stimulus for detecting pain before daily care interventions.

Pupillary dilation reflex and behavioural pain scale: Study of diagnostic test.

Background: The objective of this study was to assess the value of the pupillary dilation reflex as an assessment pain tool in critically ill patients. It is important to continue working for the well-being and security of critically ill patients.

Methods: We studied the diagnostic accuracy of the pupillary dilation reflex against the Behavioral Pain Scale.
