Efficacy of pectoralis nerve blocks I & II with liposomal bupivacaine in patients undergoing elective breast reduction procedures: A retrospective study.

Background: The pectoral nerve (PECs) block I and II nerve blocks with liposomal bupivacaine (LB, Exparel) are used for postoperative analgesia in breast surgery, but evidence on efficacy for breast reduction is limited. We examined the effect of the PECS I and II blocks with LB on perioperative opioid use and pain scores compared to no block and blocks with plain local anesthetic (LA). We hypothesized that patients receiving a block with LB would require lower opioid amounts.

Liposomal Bupivacaine via an Adductor Canal Block Compared to a Peripheral Nerve Catheter and No Block After Total Knee Arthroplasty: A Retrospective Analysis.

Background As total knee arthroplasty is one of the most common surgeries in the United States, it is important to identify regional anesthesia methods that optimize patient recovery. This study evaluates the effectiveness of adductor canal (AC) blocks with liposomal bupivacaine (LB) compared to other regional anesthesia techniques. We hypothesized that patients receiving single-shot (SS) AC blocks with LB would have lower postoperative opioid consumption compared to other groups.

Associations of Co-Occurring Chronic Conditions With Use of Rehabilitation Services in Older Adults With Back Pain: A Population-Based Cohort Study.

Objective: The objective was to examine the associations of number and type of chronic conditions with the use of rehabilitation services among older adults with bothersome back pain.

Methods: We conducted a cohort study using the National Health and Aging Trends Study, a longitudinal survey of Medicare beneficiaries ≥65 years. We included community-dwelling older adults with bothersome back pain in 2015.

Carotid Blood Flow as a Surrogate for Pulse Contour Analysis in Assessment of Fluid Responsiveness: A Prospective, Observational, Single-Centre Study (Contour Study).

Background and objectives The quest for an accurate and reliable non-invasive method of assessing cardiac output in critically ill patients is still ongoing. Carotid artery Doppler is a promising non-invasive, reproducible, and feasible bedside monitor. So we compared the change in cardiac output derived from arterial pressure waveforms (pulse contour analysis) with that from carotid artery Doppler-derived measurements, in post-major elective abdominal surgery patients.
