Summary

Introduction- During laparoscopic procedures surgical field exposure is one of the crucial aspects for a successful surgery. Exposure can be optimized by pneumoperitoneum, positioning of the patient and muscle relaxation.

The European Association for Endoscopic Surgery has recommended using the lowest intraperitoneal pressure allowing adequate exposure of the operative field rather than using a routine pressure. A way to lower intraabdominal pressure during laparoscopic procedures is to employ a deeper level of neuromuscular blockade.

Intravenous (IV) opioids such as fentanyl and remifentanil are commonly used to provide analgesia and supplement sedation during general anesthesia.

In terms of analgesia, management of intraoperative stress, remifentanil exhibits similar effects to fentanyl in adult healthy volunteers and surgical patients.

In clinical practice, if the surgeon asks for relaxation toward the end of the surgery, then many anesthesiologists will increase the dose of the IV opioids. In our experience the use of remifentanil achieves a better muscle relaxation and surgical space exposure with a lower intraabdominal pressure and less need for a neuromuscular blockage as compared to fentanyl.

Thus, the investigators aimed to compare the use of fentanyl versus remifentanil during laparoscopic hysterectomy. Because surgical complications due to inadequate exposure are a rare event, the typical way to study this issue is to use surgeon's satisfaction score.
