ClinConnect Summary

This clinical trial is studying how a standardized way of managing the placement of a device called a laryngeal mask airway (LMA) can help reduce problems for elderly patients during surgery. The LMA is used to keep the airway open and is often preferred over traditional methods because it is easier to use and causes less discomfort. However, if it is not placed correctly, it can lead to complications such as sore throat or even more serious issues, particularly in older adults who may have other health concerns. The researchers want to find out if better management and monitoring of the LMA can lower these risks.

To be eligible for the trial, participants must be at least 60 years old and scheduled for certain types of elective surgeries that are expected to last between 30 minutes and 2 hours. They should also be in relatively good health, with no severe breathing problems or other conditions that could complicate the surgery. If you decide to take part in this study, you can expect to receive careful monitoring of the LMA during your surgery, which aims to make the experience safer and more comfortable. This research is important because it could lead to improved practices that benefit older patients during their surgical procedures.
