AI Article Synopsis
- The study aimed to compare the effects of an interscalene brachial plexus block using bupivacaine or levobupivacaine along with general anesthesia on desflurane consumption in patients undergoing arthroscopic shoulder surgery.
- The research involved 60 patients, who were randomly assigned to receive either general anesthesia alone or in combination with one of the two blocks, measuring various recovery and pain-related outcomes.
- Results showed that both bupivacaine and levobupivacaine groups used less desflurane compared to the general anesthesia-only group, leading to quicker recovery times and better pain management post-surgery.
Article Abstract
Background: The goal of this study was to compare the influence of an interscalene brachial plexus block (ISB) performed with either bupivacaine or levobupivacaine in conjunction with general anaesthesia (GA) on desflurane consumption, which was titrated to maintain the recovery profiles and postoperative analgesia while also keeping the bispectral index score (BIS) between 40 and 60 in patients undergoing arthroscopic shoulder surgery.
Methods: Sixty patients undergoing arthroscopic shoulder surgery were prospectively randomized to receive GA with desflurane alone (group C) or in combination with a preoperative ISB by either bupivacaine 0.25 % (group B) 40 ml or levobupivacaine 0.25 % (group L) 40 ml. BIS scores or respiratory and hemodynamic parameters during the operation, recovery characteristics, consumed doses of desflurane and pain intensities were evaluated.
Results: The eye opening time was 4.0 ± 2.5 minutes for group B, 4.6 ± 2.4 minutes for group L, and 6.2 ± 2.1 minutes for group C (p < 0.05). Group B and group L saved 36 % and 25 % desflurane per unit time respectively when compared with group C (p < 0.001and p < 0.05) while the mean pain scores and analgesic requirements the first day after surgery were higher in group C (p < 0.05).
Conclusions: Because of lower desflurane consumption, a superior recovery profile, and a high degree of patient acceptance, general anaesthesia in combination with interscalene block may be preferred in arthroscopic shoulder surgery.
Trial Registration: The trial registration number is ACTRN12613000381785.

The Superior Glenoid Humeral Ligament's Role in Superior Labrum Anterior-Posterior Lesions and Subtype Classification Based on Arthroscopic Views: A Multicenter, Retrospective Study.

Background: Superior labrum anterior-posterior (SLAP) lesions are common shoulder injuries. The 10-type classification system has been widely used to diagnose SLAP lesions since it was proposed. However, growing evidence from arthroscopic studies indicates the existence of many SLAP lesions, especially those associated with superior glenoid humeral ligament (SGHL) injuries, that were not included in the initial classification.
View Article and Find Full Text PDFBackground: Clinical studies have shown that the open Latarjet procedure (OLP) has lower recurrence rates than the isolated arthroscopic Bankart (IAB) procedure for recurrent anterior shoulder instability, but no long-term comparative studies exist for IAB in patients without bone loss.
Purpose/hypothesis: This study aimed to compare the outcomes of IAB in selected patients without bone loss versus OLP. The hypothesis was that OLP would be more successful in preventing recurrence, even in carefully selected patients for IAB.
Background: Traumatic anterior shoulder dislocation is the most common type of joint dislocation, with an incidence of 11 to 29 per 100 000 persons per year. Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.
Methods: This review is based on pertinent publications (2014-2024) that were retrieved by a selective search in the PubMed and Google Scholar databases.

Purpose: The purpose of this study was to evaluate sex-based disparities in outcomes following surgery for anterior shoulder instability and to assess the quality of the current literature on this topic.
Methods: Following PRISMA guidelines, a June 2023 database search (PubMed, Web of Science, Embase, Cinahl) identified level I-III clinical studies on anterior shoulder instability (Jan 2003-May 2023). Eligible studies included male and female outcomes after anterior shoulder stabilization.

Purpose: The purpose of this study is to compare postoperative healthcare utilization, prescriptions, and shoulder surgery between patients with an acute depressive episode (ADE) and those without an acute depressive episode (NADE) within 3 months before arthroscopic rotator cuff repair.
Methods: Diagnostic and procedural codes were used to identify patients in the TriNetX Research Network at least 18 years of age and underwent arthroscopic rotator cuff repair between January 2010 and November 2021. Patients with a previous rotator cuff repair or diagnosis of recurrent major depressive disorder were excluded.
