Lung Function After Robot-assisted Radical Prostate Ectomy

Investigation of the Possible Advantages of the AirSeal-system Compared to Conventional CO2 Insufflation Systems in Terms of Lung Function and Hemodynamics in Robot-assisted Laparoscopic Radical Prostate Ectomy

The aim of our study is to investigate if the use of the AirSeal insufflation system impairs the lung function of patients less than a conventional system in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). Therefore we examine the lung function before and after surgery.

As a second purpose of the study, in a subgroup, we investigate the influence of the gas insufflators (AirSeal and conventional) on hemodynamics during surgery. Furthermore we study the change in the lung perfusion-ventilation-ratio by using the electric impedance tomography technique.

Inclusion Criteria:

• Patients scheduled for RALP
• Written informed consent
• ≥ 18 years of age

Exclusion Criteria:

• Age under 18 years
• Patients who refuse participating in the study
• Obstructive airway disease (COPD and Asthma)
• Postoperative admission to an intensive or intermediate care unit
• Patients who do not speak German or English
