This study aims to assess consequences and causes of hemidiaphragmatic paralysis for ambulatory arthroscopic shoulder surgery in patients with BMI ≥ 30 kg/m².
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.
Study Type
OBSERVATIONAL
Enrollment
82
A diaphragmatic assessment will be performed using ultrasound. This is a pain free assessment. This assessment is commun in our unit after arthroscopic shoulder surgery.

Failure of outpatient arthroscopic shoulder surgery strategy
failure of outpatient arthroscopic shoulder surgery strategy is communly associated with dyspnea or hypoxia due to diaphragmatic paralysis
Time frame: the first 6 hours
Assessment of peripheral nerve block strategy associated with diaphragmatic paralysis
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
Time frame: the first 2 hours
