Brief Summary

This work aims to compare lidocaine and dexmedetomidine infusions for intraoperative bleeding in patients undergoing functional endoscopic sinus surgery.

Conditions

Lidocaine; Dexmedetomidine; Infusion; Intraoperative Bleeding; Functional Endoscopic Sinus Surgery

Outcome Measures

Primary Outcomes (1)

• Surgical field

  Surgical field will be assessed by Fromme et al. scale. (0-no bleeding, 1-slight bleeding, no suctioning of blood required, 2-slight bleeding occasional suctioning required, surgical field not threatened, 3-slight bleeding - frequent suctioning required. Bleeding threatens surgical field as few seconds after suction will be removed, 4-moderate bleeding - frequent suctioning required, bleeding threatens surgical field directly after suction will be removed, 5-severe bleeding - constant suctioning required, bleeding appeared faster than removed by suction. The surgical field severely threatened, and surgery not possible). The ideal category scale value will be determined to be ≤3.

  Intraoperatively

Secondary Outcomes (7)

• Total morphine consumption

  24 hours postoperatively

• Heart rate

  Till the end of surgery (Up to 4 hours)

• Mean arterial pressure

  Till the end of surgery (Up to 4 hours)

• Time to the first request for the rescue analgesia.

  24 hours postoperatively

• Degree of pain

  24 hours postoperatively

Study Arms (2)

Lidocaine group

EXPERIMENTAL

Patients will receive lidocaine (1.5 mg/kg loading then 1mg/kg/h infusion) just after induction of anesthesia induction and continued until the end of the operation.

Drug: Lidocaine

Dexmedetomidine group

EXPERIMENTAL

Patients will receive 1 μg/kg dexmedetomidine infusion over 10 min as a loading dose then 0.4-0.7 μg/kg/h just after induction of anesthesia induction and continued until the end of the operation.

Drug: Dexmedetomidine

Interventions

Lidocaine DRUG

Patients will receive lidocaine (1.5 mg/kg loading then 1mg/kg/h infusion) just after induction of anesthesia induction and continued until the end of the operation.

Lidocaine group

Dexmedetomidine DRUG

Patients will receive 1 μg/kg dexmedetomidine infusion over 10 min as a loading dose then 0.4-0.7 μg/kg/h just after induction of anesthesia induction and continued until the end of the operation.
