Diaphragmatic Paralysis in Arthroscopic Shoulder Surgery

Completed

• Conditions: Analgesia; Dyspnea; Hypoxia

• Registration Number: NCT03192865
• Lead Sponsor: Clinique Medipole Garonne

Brief Summary

This study aims to assess consequences and causes of hemidiaphragmatic paralysis for ambulatory arthroscopic shoulder surgery in patients with BMI ≥ 30 kg/m².

Detailed Description

This prospective observational study will screen patients with body mass index (BMI) ≥30 kg/m² undergoing acromioplasty or supraspinatus tendon repair. Occurrence of post-operative hemidiaphragmatic paralysis will be observed using M-mode ultrasonography and its consequences on patient ventilation: arterial oxygen saturation, dyspnea, success of ambulatory procedure. Causes of diaphragmatic paralysis will be analyzed.

Primary Outcome Measures

Name	Time	Method
Failure of outpatient arthroscopic shoulder surgery strategy	the first 6 hours	failure of outpatient arthroscopic shoulder surgery strategy is communly associated with dyspnea or hypoxia due to diaphragmatic paralysis

Secondary Outcome Measures

Name	Time	Method
Assessment of peripheral nerve block strategy associated with diaphragmatic paralysis	the first 2 hours	Different strategies of peripheral nerve block can be proposed for post-operative pain relief in arthroscopic shoulder surgery.; All strategies were grouped in 3 parts: * Interscalene block with high volume of local anesthetics; * Interscalene block with low volume of local anesthetics; * distal block
