Eligibility
Inclusion criteria
Inclusion criteria: Age between 18 and 80 years; both sexes; American Society of Anesthesiologists of 1 to 3; body mass index between 20 and 35 kilogram per square meter; undergoing elective arthroscopic shoulder surgery
Exclusion criteria
Exclusion criteria: Patients unable to consent to the study; have neuropsychiatric diseases; cognitive impairment or altered mental status; pre-existing obstructive or restrictive pulmonary disease; coagulopathy; sepsis; hepatic or renal failure; glomerular filtration rate less than 30 ml per minute; pregnancy; known or suspected allergy to medications used during anesthesia; chronic pain condition requiring the ingestion of opioids at home and previous surgery in the neck or infraclavicular region ipsilateral to the operated limb
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the prevalence of ipsilateral hemidiaphragmatic paralysis after brachial plexus block, assessed by a blinded investigator using M-mode ultrasonography. Diaphragmatic function will be evaluated at 30 minutes after block performance, 30 minutes after admission to the post-anesthesia care unit, and 180 minutes after admission to the post-anesthesia care unit. Hemidiaphragmatic paralysis will be defined as absence of diaphragmatic movement or paradoxical cranial movement during deep inspiration. It is expected that patients receiving the costoclavicular brachial plexus block will have a significantly lower prevalence of hemidiaphragmatic paralysis than patients receiving the interscalene brachial plexus block | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes will include postoperative analgesic outcomes and safety variables. Pain intensity will be assessed using the Visual Analogue Scale before surgery, during block performance, at admission to and discharge from the post-anesthesia care unit, and at 2, 4, 6, 12, 24, and 48 hours after surgery. Additional secondary outcomes will include time to first pain complaint, perioperative and rescue morphine consumption, intraoperative and postoperative adverse events, and patient satisfaction with the anesthetic technique. It is expected that the costoclavicular block will provide postoperative analgesia comparable to the interscalene block | — |
