Summary

Alveolar recruitment manoeuvre plays a key role in the prevention of atelectasis. In addition, it affects haemodynamic parameters. This study aims to investigate the effects of RM on haemodynamic parameters using minimally invasive monitoring techniques.

Detailed description

During laparoscopic hysterectomy, pneumoperitoneum is created with carbon dioxide (CO₂) to provide surgical field of view and the patient is placed in Trendelenburg position. This increases intrathoracic pressure, decreases lung compliance and increases the risk of atelectasis. Therefore, lung protective ventilation strategies such as alveolar recruitment manoeuvre (RM), individualised PEEP application and low tidal volume are recommended. RM aims to increase lung compliance and prevent atelectasis by reopening collapsed alveoli. However, changes in haemodynamic parameters, especially mean arterial pressure and cardiac output, may occur during RM. In addition to standard monitoring for the management of these changes, haemodynamic evaluation can be performed with minimally invasive methods such as arterial waveform analysis. In this study, we aimed to evaluate the effects of RM applied during laparoscopic hysterectomy on intraoperative haemodynamic parameters using arterial waveform analysis.
