At an anesthesiology center in Abu Dhabi, the duration of anesthesia effects can vary significantly depending on the type used and the individual patient. Local anesthesia may wear off within a few hours, while general anesthesia for a major surgery may have residual effects for a few days, including grogginess, nausea, and occasional memory lapses. Regional anesthesia, such as an epidural, can last several hours. Post-operatively, pain management may involve further use of anesthetics. Having a caregiver available to help after anesthesia is important, as full cognitive and motor skills recovery may take some time.
