Summary

Laparoscopic cholecystectomy is one of the regularly performed laparoscopic surgical procedures. It resulted in shorter hospital stays, improved cosmetic outcomes, and reduced bleeding and pain. However, during laparoscopic surgeries, the pneumoperitoneum is known to raise intracranial pressure (ICP), reduction in cerebral blood flow (CBF), and as a consequence, cerebral hypoxia. There are various possible advantages of low-flow anesthesia. During laparoscopic procedures, low-flow anesthesia may be used as a means of preventing a rise in intracranial pressure and cerebral hypoxia. But low flow anesthesia effects on İCP are not known in Laparoscopic cholecystectomy. The primary aim of this study is to compare the effects of low-flow (0.75 l/min) and normal-flow (1.5 l/min) anesthesia on ONSD in patients undergoing laparoscopic cholecystectomy. Seconder aims are regional cerebral oxygen saturation (rSO2), bispectral index (BIS), and evaluate the status of cognitive function in the postoperative 24th hours.

Conditions

  • Intracranial Hypertension

Interventions

PROCEDURE

Low flow technique in general anesthesia

It will be used a low flow technique by giving airflow as 0.75 l/min after the intubation and will keep going on until the end of the laparoscopic cholecystectomy.
