Hemodynamics monitoring during laparoscopic cholecystectomy : use of thoracic electrical bioimpedance (teb)‎

الملخص EN

Background / Aim : the laparoscopic cholecystectomy approach has become increasingly popular since it has been demonstrated to be a safe and reliable technique with several advantages over standard open technique.

By using Thoracic electrical bio impedance (TEB) in this study, we were able to measure the effects of anesthesia, pneumoperitoneum, and patient position on the hemodynamic profile over time.

Materials and Methods : by the use of TEB, mean arterial blood pressure (MAP), heart rate (HR), cardiac index (CI) and stroke index (SI) were measured at nine points in time during laparoscopic cholecystectomy.

Results : 35 patients were encountered in this study.

There were hemodynamic changes during the procedure.

These changes were significant following anesthesia and C02 insufflation.

It gradually neutralized till reached normal levels after C02 disinflation and by the end of procedure in the recovery room.

Conclusion : although it is a tremendous advance for patients, laparoscopic cholecystectomy can be associated with a significant reduction in cardiac output and blood pressure.

Both surgeons and anesthesiologists must be alert to these changes.

We propose careful hemodynamic monitoring during these procedures.
