简要总结

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

详细描述

Sinus surgery is one of the most prevalent surgeries on the ear, nose, and throat (ENT). It is mainly carried out through endoscopy and significantly improves the clinical symptoms of patients with rhinosinusitis. Safe conditions must be maintained for this surgery, and the major problem reported during functional endoscopic sinus surgery (FESS) under general anesthesia (GA) is impaired visibility due to excessive bleeding.

Dexmedetomidine is an α2-adrenoceptor agonist with sedative, anxiolytic, sympatholytic, analgesic-sparing effects and minimal depression of respiratory function. It is potent and highly selective for α2-receptors.

Lidocaine is an amino amide-type short-acting local anesthetic (LA). It has a short half-life and a favorable safety profile and is,, therefore,, the LA of choice for continuous IV administration.

研究组 & 干预措施

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.

干预措施: Lidocaine (Drug)

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.

干预措施: Dexmedetomidine (Drug)

结局指标

主要结局

Surgical field

时间窗: Intraoperatively

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.

次要结局

  • Mean arterial pressure(Till the end of surgery (Up to 4 hours))
  • Total morphine consumption(24 hours postoperatively)
  • Heart rate(Till the end of surgery (Up to 4 hours))
  • Incidence of adverse events(24 hours postoperatively)
  • Degree of patient satisfaction(24 hours postoperatively)
  • Time to the first request for the rescue analgesia.(24 hours postoperatively)
  • Degree of pain(24 hours postoperatively)
