Objectives: This study aimed to evaluate the effect of serratus anterior plane block (SAP) on postoperative morphine consumption. We aimed to determine the differences between both similar blocks and evaluate the effect of the methods of application of this block on patients' postoperative pain scores and morphine consumption.
Material And Methods: This study is a single-center, prospective and observational study performed with 40 volunteer patients with American Society of Anesthesiologists (ASA) I-III, who were 18-70 years of age, scheduled for breast surgery. A total of 40 patients who underwent general anesthesia were divided into two groups each with 20 patients. While SAP block was applied to the study group, no block was applied to the control group. SAP block was made by injecting a total of 40 ml of 0.25% bupivacaine between 2 muscles after the test dose was injected with saline. All patients were followed up for 12 hours postoperatively with patient-controlled analgesia (PCA) pump. Morphine consumption, visual analogue score (VAS) values and side effects were recorded at the postoperative 1st, 6th and 12th hours.
Results: There was no significant difference between the two groups in terms of hemodynamic parameters and demographic data. Postoperative morphine consumption and postoperative analgesic requirement were significantly lower in the SAP block group (p <0.001). Postoperative VAS values were significantly lower in the SAP block group (p <0.001). No complication was observed related to the block.
Conclusion: It was found that the SAP block reduced morphine consumption, significantly decreased VAS values, and reduced side effects due to opioids postoperatively.

Opioid Consumption Following Isolated and Recurrent Shoulder Dislocation and Reduction.
J Shoulder Elbow Surg
January 2025
Department of Orthopaedics; University Hospital Cleveland Medical Center, Cleveland, OH, USA.
Background: Recurrent shoulder dislocations often lead to multiple encounters for reduction and eventual surgical stabilization, both of which involve exposure to opioids and potentially increase the risk of chronic opioid exposure. The purpose of our study was to characterize shoulder instability and compare pre- and post-reduction opioid usage in singular dislocators (SD) and recurrent dislocators (RD).
Methods: This retrospective study was performed at a single academic institution using a prospective database.
A systematic review and meta-analysis on the effects of intravenous dexamethasone on postoperative outcomes in patients undergoing total knee arthroplasty.

Purpose: Dexamethasone has shown promising efficacy in alleviating pain and enhancing outcomes undergoing TKA. However, an optimal route of administration, dosage, and treatment duration have not yet been established. This study is to assess the effects of intravenous dexamethasone administration on postoperative pain management and prognosis in patients undergoing TKA.

Background: We have previously demonstrated that an extrafascial injection of 20 ml of local anaesthetic for interscalene brachial plexus block (ISB) reduces the rate of hemidiaphragmatic paralysis by 70% compared with an intrafascial injection, with similar efficacy. In this double-blind trial, we tested the hypothesis that a local anaesthetic volume of 10 ml injected extrafascially would reduce the rate of hemidiaphragmatic paralysis vs a volume of 20 ml, while providing similar analgesia.
Methods: Sixty ASA physical status 1-3 patients scheduled for elective shoulder surgery under general anaesthesia were randomised to receive ultrasound-guided extrafascial ISB using ropivacaine 0.
Adductor Canal Block Combined With IPACK Block for Postoperative Analgesia After Total Knee Arthroplasty: A Retrospective Cohort Study.

Department of Orthopedic Surgery, West China Hospital, Sichuan University, Chengdu, China.
Background: There is no consensus on whether adductor canal block (ACB) combined with infiltration between the popliteal artery and capsule of the posterior knee (IPACK) block can further increase analgesia and reduce opioid consumption after total knee arthroplasty (TKA) compared with ACB and periarticular infiltration analgesia (PIA).
Purpose: This study aimed to evaluate the effectiveness of combining ACB and PACK block on analgesia and functional recovery following TKA.
Methods: A retrospective cohort study was conducted involving 386 patients who underwent primary unilateral TKA at our institution from January 2020 to October 2022.
Transversus abdominis plane block combined with intrathecal fentanyl versus intrathecal morphine for post-cesarean analgesia: a randomized non-inferiority clinical trial.

Background: Intrathecal morphine is the standard for post-cesarean analgesia but often causes pruritus and may be unavailable in resource-limited settings. This study assessed whether a combination of bilateral transversus abdominis plane (TAP) block and intrathecal fentanyl provides non-inferior analgesia compared with intrathecal morphine following cesarean delivery within the multimodal analgesia context.
Methods: Eighty mothers were randomized to receive either intrathecal fentanyl 10 µg with bilateral TAP block using 15 mL of 0.
