Association between anesthesia technique and death after hip fracture repair for patients with COVID-19.

Purpose: Patients with COVID-19 undergoing hip fracture surgeries have a 30-day mortality of up to 34%. We aimed to evaluate the association between anesthesia technique and 30-day mortality after hip fracture surgery in patients with COVID-19.

Methods: After ethics approval, we performed a retrospective cohort analysis of the American College of Surgeons National Surgical Quality Improvement Program data set from January to December 2021.

Association of anaesthesia technique with 30-day primary graft patency after open lower limb revascularization: retrospective cohort study.

Background: The relationship between anaesthetic technique and graft patency after open lower limb revascularization is unclear. The aim of this study was to evaluate the association between 30-day graft patency after elective infrainguinal bypass and anaesthetic technique (regional anaesthesia (RA, i.e.

Development and internal validation of a multivariable risk prediction model for severe rebound pain after foot and ankle surgery involving single-shot popliteal sciatic nerve block.

Background: Rebound pain occurs after up to 50% of ambulatory surgeries involving regional anaesthesia. To assist with risk stratification, we developed a model to predict severe rebound pain after foot and ankle surgery involving single-shot popliteal sciatic nerve block.

Methods: After ethics approval, we performed a single-centre retrospective cohort study.

COVID-19 and breast cancer at a Regional Breast Centre: our flexible approach during the pandemic.

Purpose: In British Columbia (BC), there have been 2790 confirmed COVID-19 cases as of June 20, 2020. The aim of this project is to capture the effect of COVID-19 on the volume of surgery and adaptations to the surgical care of patients at a breast centre in BC.

Methods: All proven or suspected breast cancer cases treated with surgery between March 16, 2019 and April 30, 2019 and March 16, 2020 and April 30, 2020 through the Providence Breast Centre were included in this review.

Pecto-intercostal Fascial Block for Acute Poststernotomy Pain: A Case Report.

Sternotomy pain is a common complication after cardiac surgery. We present a 77-year-old patient with severe acute sternal pain after coronary artery bypass graft surgery who was successfully treated with a novel peripheral regional anesthetic technique, the pecto-intercostal fascial block. This interfascial plane block may represent an effective regional anesthetic component of a multimodal analgesic strategy for cardiac surgery patients who suffer from significant pain after a median sternotomy and are typically anticoagulated.

Effect of Beam Steering on Echogenic and Nonechogenic Needle Visibility at 40°, 50°, and 60° Needle Insertion Angles.

Currently, there is little understanding of the role of echogenic needles and beam steering at moderate angles of needle insertion. The ultrasound images of the echogenic and nonechogenic needles inserted into pork at 40°, 50°, and 60° were scored by anesthesiologists on a scale of 0-10. The effect of different levels of beam steer was also explored.

Hyperbaric Versus Isobaric Bupivacaine for Spinal Anesthesia: Systematic Review and Meta-analysis for Adult Patients Undergoing Noncesarean Delivery Surgery.

Background: It is widely believed that the choice between isobaric bupivacaine and hyperbaric bupivacaine formulations alters the block characteristics for the conduct of surgery under spinal anesthesia. The aim of this study was to systematically review the comparative evidence regarding the effectiveness and safety of the 2 formulations when used for spinal anesthesia for adult noncesarean delivery surgery.

Methods: Key electronic databases were searched for randomized controlled trials, excluding cesarean delivery surgeries under spinal anesthesia, without any language or date restrictions.

Intrathecal hyperbaric versus isobaric bupivacaine for adult non-caesarean-section surgery: systematic review protocol.

Introduction: Bupivacaine is the most commonly used local anaesthetic for spinal anaesthesia (SA). There are two forms of commercially available bupivacaine; isobaric bupivacaine (IB): a formulation with a specific gravity or density equal to cerebrospinal fluid, and hyperbaric bupivacaine (HB): a formulation with density heavier than cerebrospinal fluid. The difference in densities of the two available preparations is believed to affect the diffusion pattern that determines the effectiveness, spread and side-effect profile of bupivacaine.
