ClinConnect Summary

The MAAS Method clinical trial is looking at a new way to deliver anesthesia during certain types of surgeries, specifically using two anesthetic gases called sevoflurane and desflurane. The goal is to see how accurately a special device called the Minimal-flow Autocontrol Anesthesia System can provide the right amount of these gases to keep patients comfortable and safe while they are under anesthesia. Researchers will monitor how many times adjustments need to be made to keep the levels of anesthesia steady and will also check how long it takes to reach the desired levels.

To be part of this study, participants must be adults scheduled for specific robotic surgeries and must provide written consent. However, certain health conditions, such as severe lung disease or heart issues, may exclude individuals from participating. Those who join the trial can expect to receive tailored care during their procedure, focused on maintaining their lung function. Your participation will help researchers better understand how to improve anesthesia delivery for future patients.
