Introduction
Laparoscopic gynecologic surgery is one of the most well-known procedures. Pneumoperitoneum with carbon dioxide insufflation can cause unfavorable hemodynamic effects due to catecholamine and vasopressin release.

Aim
To examine the effects of stellate ganglion block on hemodynamic response and postoperative pain.

Material and methods
In a prospective double blinded randomized parallel study we included 40 patients with ASA physical status I and II, aged between 18 and 50 years with a gynecologic problem candidate for laparoscopic surgery under general anesthesia. The patients were randomly divided into two groups. Fifteen minutes before anesthesia induction, the patients underwent ultrasound guided stellate ganglion block with 10 ml of lidocaine 1% and the control group underwent stellate ganglion block using 10 ml of distilled water as placebo. After induction of general anesthesia, systolic and diastolic blood pressure and heart rate were recorded, especially after blowing of CO2 gas, the position change, depletion of CO2, and tracheal extubation in recovery. The postoperative pain was calculated using the visual analogue scale (VAS) at three times (0, 30, and 24 h after surgery).

Results
Our results showed that mean systolic and diastolic blood pressure and heart rate did not show any significant difference at the measurement times (p > 0.05), and mean VAS of patients in the two groups was significantly different for the three measurement times except 24 h after surgery (p < 0.05).

Conclusions
Stellate ganglion block before laparoscopic gynecologic surgery has no significant effect on intraoperative and postoperative hemodynamic responses; however, it can decrease VAS in the early postoperative period.
