Preoperative Anxiety

Preoperative anxiety is the emotional distress, worry, or fear that occurs before surgery, often in response to uncertainty, anesthesia, pain, and possible outcomes. In patients undergoing cancer procedures, anticipating surgery can activate the sympathetic nervous system and stress-hormone pathways, producing symptoms such as heightened heart rate, poor sleep, and difficulty concentrating. Researchers assess these responses through validated questionnaires, clinical interviews, and physiological measures to examine effects on patient well-being, treatment experience, and recovery. Studying preoperative anxiety can guide communication, psychological support, and other interventions that improve perioperative care and inform patient-centered cancer research.

Anxiety is a commonly observed behavioral disorder that stems from fear. It is described as increased restlessness, or unpleasant feelings of fear over anticipated events. Experimenters often use rodent models to better understand anxiety disorders in humans. They use different paradigms, like exposing rodents to bright spaces or loud sounds, which are known to induce fear. These tests combined with other interventions such as surgery or drug-administration may assist researchers in pinpointing...

The plus-maze measures anxiety-like behaviour in rodents. There are two opposite closed and two opposite open arms; anxious rodents avoid the open arms. The central area is neither completely open nor closed, so time spent here is ambiguous and difficult to interpret. Here a modification of the plus-maze protocol eliminating this area is described.
