PENG vs SIFI Block for Positioning Pain During Spinal Anesthesia

Study Overview
=================
Brief Summary
-----------------
This study aims to compare the effectiveness of preoperative ultrasound-guided suprainguinal fascia iliaca compartment block (SFICB) and pericapsular nerve group block (PENG) in preventing positioning pain during spinal anesthesia in patients who are scheduled for surgery due to hip fracture.

Detailed Description
-----------------
Patients to whom an analgesic block was placed (either PENG or SIFI compartment analgesic block) to ameliorate positioning pain during spinal anesthesia for hip fracture surgery will be enrolled after written consent is obtained. Patients will be asked to report their pain intensity while sitting and their sitting angle will be measured. Patients will be observed for any possible complications( LAST, allergic reactions, hypotension, bradycardia). Pain intensity will then again be questioned postoperatively along with analgesic consumption at the 24th hour. Patients will be arranged into two cohorts according to the block (PENG vs SIFI) and the data obtained will be compared between two cohorts.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Positioning pain during spinal anesthesia with 10-point numeric rating scale (NRS) | NRS is a self-reported pain scale where patient defines intensity of their pain on a scale of 0 to 10. Zero means the patient has no pain while ten means the patient is experiencing the worst pain possible | 30 minutes after the block is placed | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sitting angle during positioning | Angle of sitting in degrees measured with a protractor during sitting for spinal anesthesia | 30 minutes after the block is placed | 
| Postoperative pain with 10-point numeric rating scale (NRS) | NRS is a self-reported pain scale where patient defines intensity of their pain on a scale of 0 to 10. Zero means the patient has no pain while ten means the patient is experiencing the worst pain possible | Postoperative day 1 |
