The Effect of Bilateral Infraorbital+ Infratrochlear Nerve Block for Rhinoplasty Operations

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Remifentanil consumption | We will compare the remifentanil consumption for the block performed and non-block group | 6 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Surgical bleeding grading | We will compare the surgical bleeding scores for the block performed and non-block group | 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 | 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 | 6 hours | 
| Post-operative nausea and vomiting | We will compare the Post-operative nausea and vomiting for the block performed and non-block group | 6 hours | 
| Need for analgesic after surgery | We will compare the Need for analgesic after surgery for the block performed and non-block group | 6 hours |
