INTRODUCTION: This systematic review and meta-analysis aimed to assess the efficacy and safety of interscalene brachial plexus block (ISB) techniques in upper limb and shoulder surgeries. EVIDENCE ACQUISITION: We conducted a comprehensive search of PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase, Medline, and Scopus databases up to May 14th , 2023. We employed a search strategy involving keywords such as "brachial plexus block," "interscalene brachial plexus block," "ISB," "extrafascial," and "intrafascial," without applying search restrictions or filters...

BACKGROUND: The erector spinae plane block is a relatively new regional anesthesia technique that is expected to provide some benefits for postoperative analgesia. This study investigated the effects of erector spinae plane block on postoperative opioid consumption in kidney donors undergoing hand-assisted laparoscopic donor nephrectomy for renal transplantation. METHODS: Fifty-two donors scheduled for elective hand-assisted laparoscopic donor nephrectomy were randomly divided into the block (25 donors) and control (27 donors) groups...

INTRODUCTION: Postoperative cognitive impairment is common in surgical patients, including postoperative delirium and postoperative cognitive dysfunction. Several studies investigating the association between peripheral nerve block and the risk of cognitive impairment after thoracic surgery showed conflicting results. Therefore, we conducted the current systematic review and meta-analysis to determine the effects of peripheral nerve block on postoperative cognitive impairment in thoracic surgical patients...

BACKGROUND: Corticosteroids have become standard of care for COVID-19 but their effect on the systemic immune-inflammatory response has been little investigated. METHODS: Multicenter prospective cohort, including critically ill COVID-19 patients between March and November 2020. C-reactive protein (CRP), lymphocyte count and fibrinogen levels were collected upon hospital admission before initiation of steroid treatment and at ICU admission, three days and seven days later, along with interleukin (IL)-6, IL-10 and tumor necrosis factor-alpha (TNF-α) plasma levels...

Intervertebral disc degeneration is characterized by deterioration in structural support that is potentially followed by stimulated neuronal ingrowth, and dysfunction of cellular physiology in the disc. Discogenic low back pain originates from nociceptors within the intervertebral disc or the cartilage endplate. This narrative review examines the mechanisms of disc degeneration, the association between degeneration and pain, and the current diagnosis and treatment of discogenic low back pain. Mechanisms of disc degeneration include dysregulated homeostasis of the extracellular matrix of the disc, altered spine mechanics, DNA damage, oxidative stress, perturbed cell signaling pathways, and cellular senescence...

BACKGROUND: Short-term acid-base effects of 0.9% saline solution infusion are not well described. Aim of this study was to assess the effects of a fluid challenge with 0.9% saline in critically ill patients according to the Stewart's approach, which allows a precise determination of acid base equilibrium. METHODS: In 40 mechanically ventilated critically ill patients, acid-base variables according to Stewart's approach were measured before and after 30 minutes from the infusion of 0...

BACKGROUND: Dreaming is often reported by patients who undergo propofol-based sedation, but there have not been any studies to date focused on the incidence of dreaming and factors associated therewith following the administration of ciprofol anesthesia in patients undergoing painless gastroscopy. The present study was thus developed with the goal of assessing the incidence of dreaming. METHODS: In total, this study enrolled 200 patients undergoing painless gastroscopy...
