Not Applicable

Completed

• Conditions: Anesthesia, Local
• Interventions: Other: bilateral infraorbital+infratrochlear block

• Registration Number: NCT05671237
• Lead Sponsor: Istanbul University

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
bilateral infraorbital+infratrochlear block group	bilateral infraorbital+infratrochlear block	For this group we will perform bilateral infraorbital+infratrochlear block before surgery

Primary Outcome Measures

Name	Time	Method
Remifentanil consumption	6 hours	We will compare the remifentanil consumption for the block performed and non-block group

Secondary Outcome Measures

Name	Time	Method
Surgical bleeding grading	6 hours	We will compare the surgical bleeding scores for the block performed and non-block group
Numeric rating Scale	6 hours	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"
Post-operative nausea and vomiting	6 hours	We will compare the Post-operative nausea and vomiting for the block performed and non-block group
Richmond agitation sedation scale	6 hours	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
Need for analgesic after surgery	6 hours	We will compare the Need for analgesic after surgery for the block performed and non-block group
