Which of the following is a known risk of general anaesthetic?

Temporary confusion and memory loss are recognized risks associated with general anaesthesia, particularly in certain populations such as the elderly. These cognitive effects can occur following surgery and might be attributed to several factors, including the type and length of surgery, the medications used, and individual patient factors like age and pre-existing cognitive function.

The mechanism behind these effects generally relates to the impact of anaesthetic agents on brain function during and after the procedure. Research has shown that some patients can experience postoperative cognitive dysfunction, characterized by issues with memory, attention, and executive function. In most cases, this confusion is temporary and tends to resolve over time, but it is important for healthcare professionals to be aware of this potential outcome when planning and monitoring patient care post-surgery.

Understanding these risks can help nurses and other healthcare providers prepare patients for potential outcomes and guide them in their recovery process.
