About this trial
The purpose of this study, called a cross-sectional survey, is to interview patients on their experiences of pain and recovery following keyhole shoulder surgery, after receiving a single shot nerve block in addition to a general anesthetic. The researchers would like to explore patients' experiences to see if there are groups of patients who may benefit from insertion of a nerve catheter as compared to a single shot nerve block injection for keyhole shoulder surgery.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients receiving a single-injection PNB for outpatient arthroscopic shoulder surgery at TWH and WCH

Able to communicate in English
Disqualifiers
Cognitive impairment (inability to consent to participate in study)
Refusal to participate in study
Patients with primary block failure defined as those without a detectable sensory or motor block (determined by inability to abduct the arm and numbness or loss of sensation to pinprick over lateral shoulder/deltoid muscle, C5 dermatome)
Trial population
Patients scheduled for for an arthroscopic shoulder surgery at Toronto Western Hospital and Women's College Hospital, Toronto.

Trial groups
Trial outcomes
Primary outcomes
To determine the proportion of patients who have a preference for nerve block with a continuous infusion versus a single injection of local anesthetic
To determine the proportion of patients undergoing outpatient arthroscopic shoulder surgery who have a preference for prolongation of their peripheral nerve block with a continuous infusion versus a single injection of local anesthetic
Secondary outcomes
To determine predictive factors for catheter preference based on demographic characteristics
To determine predictive factors for catheter preference based on demographic characteristics
To determine predictive factors for catheter preference based on type and duration of shoulder surgery
To determine predictive factors for catheter preference based on type and duration of shoulder surgery
To determine predictive factors for catheter preference based on pre-operative anxiety defined by the PROMIS Anxiety Scale short form 8a
PROMIS Anxiety Scale measures self-reported anxiety traits based on 8 questions. Each question are rated on a 5-point scale (1-5) to get a total score between 5-40
To determine predictive factors for catheter preference based on pre-operative frailty
Frail scale evaluates five areas assigning 1 point for each if present and zero if absent. Total score 0-5. Robust=0; Pre-frail=1-2 and Frail=3-5
