Factors Predicting Blood Pressure Change With Interscalene Block

Konya City Hospital110 enrolled

Overview

The primary aim of this study is to identify potential anthropometric features that predict the relationship between the Interscalene Block procedure and changes in blood pressure

This prospective, randomized study will be carried out after obtaining the necessary ethical approval and informed consent from the patients. 110 adult volunteer patients who will undergo ISB for shoulder surgery anesthesia will be included in this study. Evaluation of the patients before ISB and anthropometric measurements before and after Interscalene Block will be performed by an anesthesiologist who is not involved in the study.

Outcomes

Primary Outcomes

Our primary aim in this study is to determine possible anthropometric features that will predict the relationship between interscalene block procedure and blood pressure change.

Various anthropometric measurements (such as "neck diameter", "neck length" and "anterior scalene muscle thickness") may be effective in the spread of the local anesthetic agent during ISB, and these measurements may play a role as a factor in the blood pressure change associated with ISB.

Time frame: 60 minute

Secondary Outcomes

The secondary aim of this study is to reveal the relationship between interscalene block and heart rate.

Time frame: 60 minute
