An interventional study of bilateral infraorbital+infratrochlear block in Anesthesia, Local, sponsored by Istanbul University. Completed at 1 site in Turkey. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-06-05.
Sponsored by Istanbul University · Not applicable, Interventional, and Other
The aim of our study is to examine the effect of bilateral infraorbital and infratrochlear nerve blocks for rhinoplasty operations on perioperative remifentanil need and postoperative pain scores.
Rhinoplasty operations are one of the most applied cosmetic surgeries in the world.
Depending on the procedure type and hemodynamic lability, the quality of the surgical field, perioperative and postoperative complications as well as the success of surgery are affected.To provide improved surgical field quality, controlled hypotension and high concentrations of inhalation anesthetics, magnesium sulfate, remifentanil, clonidine, calcium channel blockers, tranexamic acid, intravenous nitroglycerin have been used.
The American Society of Anesthesiology recommends using regional anesthesia methods and administering multimodal analgesia in every possible surgery. In our study we have performed bilaterral infraorbital an infratrochlear nerve blocks which are main nerves of the nose, for the patients of rhinoplasty. With blocking the infratrochlear and infraorbital nerves we will examine the need for remifentanil during surgery, postoperative pain scores.
Istanbul University is the lead sponsor of 496 studies on the registry; 80 are open to participants now.
Of its 5 completed or terminated interventional studies of FDA-regulated products, 1 (20%) have results posted.

Patients undergoing rhinoplasty surgery
Exclusion Criteria:
For this group we will perform bilateral infraorbital+infratrochlear block before surgery
Other: bilateral infraorbital+infratrochlear block
For this group we will start the surgery without performing a block
we will perform bilateral infraorbital+infratrochlear nerve block
Remifentanil consumption
We will compare the remifentanil consumption for the block performed and non-block group
Time frame: 6 hours
Surgical bleeding grading
We will compare the surgical bleeding scores for the block performed and non-block group
Time frame: 6 hours
Richmond agitation sedation scale
We will compare the Richmond agitation sedation scale for the block performed and non-block group. +4 Combative +3 Very agitated +2 Agitated +1 Restless 0 Alert and calm -1 Drowsy -2 Light sedation -3 Moderate sedation -4 Deep sedation -5 Unarousable
Time frame: 6 hours
Numeric rating Scale
We will compare the numeric rating scale for pain for the block performed and non-block group. The numeric rating scale (NRS) is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and 10 meaning "the worst pain imaginable"
Time frame: 6 hours
Post-operative nausea and vomiting
We will compare the Post-operative nausea and vomiting for the block performed and non-block group
Time frame: 6 hours
Need for analgesic after surgery
We will compare the Need for analgesic after surgery for the block performed and non-block group
Time frame: 6 hours
