About

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

Full 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.

Enrollment: 82 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• All patients with body mass index ≥ 30kg/m², undergoing ambulatory arthroscopic shoulder surgery (acromioplasty and supraspinatus tendon repair) will be screened.

Exclusion criteria

age <18 years, brachial plexus neuropathies, severe bronchopulmonary disease, acute respiratory distress, coagulopathies, systemic glucocorticoid use, pregnancy, routine use of opioid medications, intolerance for one or more medications of the study protocol and diabetes.

Trial design

82 participants in 2 patient groups

diaphragmatic paralysis/paresis group

Description:

Diaphragmatic paralysis can be associated with regional anesthesia procedure in arthroscopic shoulder surgery as phrenic nerve is close to the brachial plexus. Diaphragmatic paralysis will be defined using ultrasounds.

Treatment:

Procedure: diaphragmatic assessment using ultrasounds.

No diaphragmatic paralysis/paresis group

Description:

Some strategies of peripheral nerve block are able to spare diaphragmatic paralysis.

Treatment:

Procedure: diaphragmatic assessment using ultrasounds.
