Impact of Regional Anesthesia on Blood Pressure in Humeral Fracture Surgery

Impact of Regional Anesthesia on Blood Pressure in Humeral Fracture Surgery : Comparative Study Using Propensity-score

This study aims to compare the hemodynamic impact of two anaesthetic strategies : Regional anesthesia versus General anesthesia in proximal humeral fracture surgery.

Proximal humeral fracture surgery is frequently performed under General Anesthesia (GA).

GA is frequently associated with a high risk of hypotension with significant consequences.

Regional anesthesia could be an interesting alternative to GA in order to limit hemodynamic consequences, especially in elderly patients. Furthermore, in the current state of Covid 19 crisis, regional anesthesia could provide solutions in exposing less medical staff on patient's airway.

The investigators hypothesize that the use of Regional anesthesia reduces the use of intraoperative vasopressor during surgery.

After ethical committee approval, a retrospective cohort of patients with proximal humeral fracture, in Montpellier's University Hospital, was analyzed from 2016 to 2020. An informational note was given to all patients participating to the study.

Inclusion Criteria:

• ASA I - IV
• Proximal humeral fracture
• Operated between january 2016 and december 2020
• Emergency surgery

Exclusion Criteria:

• Surgical revision or surgery for pre-existing infection, tumour
• Intubated patient / unconscious patient
• Haemostasis disorder
• Haemostasis disorder
• Refusal of the patient
