Analgesia, Dyspnea, Hypoxia
Conditions
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.
Interventions
PROCEDUREdiaphragmatic assessment using ultrasounds.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 |
