    Patients who experience hypotension during surgery are at increased risk of postoperative delirium, according to a large study presented at the ANESTHESIOLOGY 2021 Annual Meeting.

    Postoperative delirium, changes in mental function that can cause confusion after surgery, and the most common surgical complications senior citizenCan be caused by a variety of factors, including pain, stress, insomnia, and anxiety.Previous small studies were not definitive, but 316,000 new studies Patience Hypotension during surgery Postoperative delirium.. Researchers note that low blood pressure reduces the supply of oxygen and glucose to the brain.

    “Postoperative delirium is a major obstacle to rapid recovery from surgery because patients are more likely to depend on others for activities of daily living and may accelerate cognitive decline,” said senior author Matthias. Dr. Ikerman, MD, said. Head of Research and Chair, Professor Francis F. Foldes of the Department of Anesthesiology at the Montefiore Medical Center and Albert Einstein Medical College in New York. “Our study suggests that rapid treatment of hypotension during surgery may prevent delirium and help recovery.”

    In a study of 316,717 patients who had nonHeart surgery Between 2005 and 2017, 2,183 (0.7%) were diagnosed with delirium within 30 days after surgery in one of the two hospitals.Of those patients, 41.7% had mean arterial pressure (systole and Diastolic blood pressure) Less than 55 mmHg during less than 15 minutes of surgery, 2.6% performed more than 15 minutes of surgery. Lead author Luca J. Researchers, including Wachtendorf, BS, and Omid Azimaraghi, MD, Low blood pressure Up to 60% more likely to experience postoperative delirium, and the effect was magnified in patients who had longer surgery.

    Postoperative delirium can affect anyone, but older patients are at greatest risk. Postoperative delirium usually lasts 1 to 3 days after surgery, but some patients experience long-term memory loss, which makes learning, concentration, and thinking difficult.

    “The doctor’s anesthesiologist measures the patient’s blood pressure at least every 3 minutes. Surgery“This study shows that immediate provision of drugs to raise blood pressure when it drops can help reduce the risk of postoperative delirium,” said Dr. Ackerman.
