| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Pulse pressure variation | Experimental | Pulse pressure variation will be recorded via an arterial catheter after anesthetic induction, before pneumoperitoneum, after pneumoperitoneum, before infusion of 6% hydroxyethyl starch, and after infusion of 6% hydroxyethyl starch. Stroke volume will be also measured to differentiate the fluid responders. |
