Clinical Trial Summary

This study will be carried out to compare the efficacy of dexmedetomidine, propofol or lidocaine infusions in attenuation of hemodynamic responses to pneumoperitoneum during adult laparoscopic cholecystectomy using electrical cardiometry.

Description:

Many drug infusions have been used to control hemodynamic responses to laparoscopic surgeries like propofol, fentanyl, esmolol with varying degrees of success.

Dexmedetomidine has sedative and analgesic properties seems to be appropriate enough to control the sympathetic response as well as provide a stable hemodynamics

• normal saline
Patients will receive infusion of 25 ml normal saline in 50ml syringe pump (control group).
