Study Type

OBSERVATIONAL

Conditions

Robotic Surgery Heart Failure, Systolic

Summary

The field of robotic-assisted laparoscopic surgery increases all the time. Older and more fragile patients which are not suitable for major open surgery could be scheduled for robotic- assisted surgery. The peroperative anesthesiological challenges and stresses during this type of surgery could anyway be even more prominent. The extreme positioning of patients during robotic surgery in the pelvis, often 30 degrees head down tilting (Trendelenburg positioning), should increase the work load of the heart significantly. There are no studies concerning fragile patients with heart failure during these conditions. In this study the circulatory effects in patients with normal heart function and preexisting heart failure will be studied during robotic surgery in extreme Trendelenburg positioning During surgery the work load and performance of the heart will be monitored using an esophageal doppler and optical spectrophotometry measuring regional saturation of the brain. This study can identify patients at risk of developing critical circulatory failure during this type of surgery.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is monitoring how the heart performs when patients are placed in a steep head-down position (Trendelenburg position) during robotic surgery. This position shifts blood toward the chest and can affect heart function, and the study aims to better understand and manage these changes. **You may be eligible if...** - You are 18 years or older - You are scheduled for robotic surgery that requires the steep Trendelenburg position (head-down tilt) - You are able to give written informed consent **You may NOT be eligible if...** - You are under 18 years old - You have dementia - You are unable to provide written consent Talk to your doctor to see if this trial is right for you.
