What causes emergence delirium? Emergence delirium is a side effect of general anaesthesia in children. It is caused by certain types of anaesthetic medicines (e.g. the anaesthetic gas Sevoflurane).

It is well known that ketamine may produce undesirable psychological sequelae during emergence from ketamine anaesthesia. They are termed emergence reactions and manifest themselves as vivid dreams, extracorporeal out-of-body experience, floating sensations, ‘weird trips’ and body image alterations [1].

• stage 1. stage of analgesia. begins with the administration of the anesthetic agent and ends when the patient becomes unconsious.
• stage 2. the excitment phase.
• stage 3. Surgical anesthesia state.
• stage 5. complete respitory depression.

Delayed emergence is defined as the failure to regain consciousness 30–60 minutes after general anesthesia, and the clinical presentation often involves both altered mental status and respiratory complications.

General anesthesia is, in fact, a reversible drug-induced coma. Nevertheless, anesthesiologists refer to it as “sleep” to avoid disquieting patients. Unfortunately, anesthesiologists also use the word “sleep” in technical descriptions to refer to unconsciousness induced by anesthetic drugs.

The time to emerge from anesthesia is affected by patient factors, anesthetic factors, duration of surgery, and painful stimulation. The principal factors responsible for delayed awakening following anesthesia are anesthetic agents and medications used in the perioperative period.

The condition, called anesthesia awareness (waking up) during surgery, means the patient can recall their surroundings, or an event related to the surgery, while under general anesthesia. Although it can be upsetting, patients usually do not feel pain when experiencing anesthesia awareness.

If general anesthesia is used, the anesthesiologist will start transitioning you from the normal awake state to the sleepy state of anesthesia. This is called induction, which is usually done by either injecting medicine through an IV or by inhaling gases through a mask.

Most people wake up a few hours after their brain surgery. But sometimes, your surgeon might decide to keep you asleep for a few days after surgery, to help you recover.

Here are some basic survival rate statistics, as reported by the American Cancer Society: Oligodendroglioma – 90% for patients 20-44, 82% for patients 45-54 and 69% for patients 55-64. Meningioma – 84% for patients 20-44, 79% for patients 45-54 and 74% for patients 55-64.

The risk of dying in the operating theatre under anaesthetic is extremely small. For a healthy person having planned surgery, around 1 person may die for every 100,000 general anaesthetics given. Brain damage as a result of having an anaesthetic is so rare that the risk has not been put into numbers.

How long will I be in the hospital? Usual length of stay for patients who undergo a craniotomy for a brain tumor, with no complications, is two nights, three hospital days. Patients who have postoperative difficulties may be required to stay longer.

Possible risks associated with brain surgery include:

• allergic reaction to anesthesia.
• bleeding in the brain.
• a blood clot.
• brain swelling.
• coma.
• impaired speech, vision, coordination, or balance.
• infection in the brain or at the wound site.
• memory problems.

A major surgery and its treatments can cause changes in a personality and ability to think. Patients may experience challenges with their communication, concentration, memory and emotional abilities. Most brain tumor patients exhibit signs that are consistent with depression and agitation, especially post surgery.

You are unlikely to have your whole head shaved. After the operation, your hair will grow back where it has been shaved. Once the wound on your head has healed, and your stitches or clips have been removed, you can wash your hair and use hair products as usual.

A significant hypoxic brain injury can result in coma and possibly post-coma unresponsiveness. Symptoms following a return to consciousness can include memory difficulties, abnormal movements, weakness in arms and legs, lack of coordination and visual problems.

The most rapid recovery is usually in the first six months, and by about one year the likely long-term outcome will have become clearer. However, improvement may continue for much longer after brain injury, certainly for several years, although the progress may become more modest and gradual after the first few months.

You might receive blood products and possibly fluids through an intravenous tube. Seeking immediate treatment reduces your chances of brain damage. You may also receive medication for blood pressure issues or to control your heart rate. Seizure-curbing medicines or anesthetics may also be part of your treatment.

Hypoxia is actually divided into four types: hypoxic hypoxia, hypemic hypoxia, stagnant hypoxia, and histotoxic hypoxia. No matter what the cause or type of hypoxia you experience, the symptoms and effects on your flying skills are basically the same.

A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of making a full or partial recovery. Furthermore, symptoms and effects of the injury are dependent on the area(s) of the brain that was affected by the lack of oxygen.

Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination. Brain cells are extremely sensitive to oxygen deprivation and can begin to die within five minutes after oxygen supply has been cut off.
