Researchers at MIT , Massachusetts General Hospital and Harvard Medical School have developed an automated anesthesia delivery system that aims to administer the correct dose of anesthesia to the patients , which addresses the challenge of overdosage. The device was tested on Rhesus Macaques , wherein the brain activity was monitored and the dosage of the common anesthetic , Propofol was adjusted every 20 seconds . This technique ensured that the subject remained sedated for 125 minutes without excessive drug use.
Traditionally , the dosage is determined on various factors like weight , age etc. however, there is no relation between the dose and the time of sedation . Anesthesiologists often err on the side of caution , administering higher doses to prevent any mishap . This new device combines brain monitoring equipment with algorithms to determine optimal dosage for maintaining sedated state , thereby preventing errors.
While similar devices do exist , the unique feature here is its reliance on real time feedback from brain . The researchers envision this technology as valuable tool in long surgeries , potentially reducing complications like delirium and confusion . Future steps involve refining the system through additional trials and making brain monitoring less invasive by moving to EEG electrodes attached to scalp.
