Background: Chronic-kidney-disease (CKD) is prevalent among adults undergoing noncardiac surgery, with surgery-related factors potentially worsening CKD or triggering acute kidney injury (AKI). We hypothesized that CKD patients experience more kidney function decline within one to two years post-surgery than those without CKD, particularly if they develop AKI.

Methods: We conducted a single-center retrospective cohort study, including noncardiac surgery patients with documented creatinine preoperative and between 1 and 2 years after surgery.

Introduction: The number of tracheal intubation attempts required to reach proficiency in videolaryngoscopy with hyperangulated blades is unknown. Understanding this training requirement might guide training for clinicians who perform laryngoscopy. We therefore performed a planned sub-analysis of a randomised controlled trial comparing tracheal intubation success with videolaryngoscopy vs.

Study Objectives: Alerts for vital sign abnormalities seek to identify meaningful patient instability while limiting alarm fatigue. Optimal vital sign alarm settings for postoperative patients remain unknown, as is whether alerts lead to effective clinical responses reducing vital sign disturbances. We conducted a 2-phase pilot study to identify thresholds and delays and test the hypothesis that alerts from continuous monitoring reduce the duration of vital sign abnormalities.

Purpose: Initially introduced as a safer alternative to smoking, electronic cigarettes (e-cigarettes) and vaping have since been associated with lung injury. Nevertheless, there is limited perioperative data on their potential contribution to the harmful effects of mechanical ventilation on the lungs. We hypothesized that, in adults undergoing noncardiothoracic surgeries, preoperative vaping/e-cigarette use is associated with hypoxemia during the first postoperative hour, and with an increased incidence of intraoperative and postoperative pulmonary complications.

To improve the fertility of cervical artificial insemination (AI) in sheep, we investigated isoxsuprine HCl usage on the cervical passage during cervical AI. We also compared cervical and laparoscopic AI fertility results of using chilled semen at different durations. Semen was collected from rams and diluted as 20 × 10 or 400 × 10 spermatozoa/straw for laparoscopic and cervical AI, respectively, and chilled to 4°C within 2 h.

Article Synopsis
  • A study was conducted to evaluate the effects of combining liposomal bupivacaine with plain bupivacaine on pain management after minimally invasive thoracic surgery, hypothesizing it would provide better pain relief than bupivacaine alone.
  • The research involved 189 patients and measured overall benefit of analgesia scores (OBAS), respiratory function, and opioid usage over the first three postoperative days.
  • Results showed no significant difference in pain relief, respiratory mechanics, or opioid consumption between the two groups, indicating that liposomal bupivacaine did not offer advantages over standard bupivacaine.

Introduction: Troponin elevation after noncardiac surgery is associated with an elevated risk of 30-day mortality. Little is known about relative merit of using a high-sensitivity Troponin T (hsTnT), the fifth-generation assay, vs the nonhigh sensitivity Troponin T (non-hsTnT), the fourth-generation assay, in the noncardiac surgery setting. We aimed to identify whether hsTnT can identify additional patients at risk that would have gone undetected with non-hsTnT measurement.

Most pancreatic islets are destroyed immediately after intraportal transplantation by an instant blood-mediated inflammatory reaction (IBMIR) generated through activation of coagulation, complement, and proinflammatory pathways. Thus, effective mitigation of IBMIR may be contingent on the combined use of agents targeting these pathways for modulation. CD47 and thrombomodulin (TM) are two molecules with distinct functions in regulating coagulation and proinflammatory responses.

  • The study explored if using a ureteral access sheath (UAS) during kidney surgery reduces the risk of acute kidney injury by measuring myo-inositol oxygenase (MIOX) levels.
  • Patients were divided into two groups: one that used the UAS and one that did not, with blood samples taken before and after surgery to assess MIOX levels.
  • Results showed no significant differences in MIOX changes between the two groups, indicating that low intrarenal pressure can be maintained without UAS, suggesting its necessity may be questioned.

  • The study examined the blood concentration levels and potential toxicity of using a mix of plain and liposomal bupivacaine in thoracic fascial plane blocks during surgery.
  • Eighteen adult patients were involved, with results indicating significant variability in plasma levels; the highest concentration was reached about 30 minutes post-injection, with some patients exceeding the toxic threshold.
  • Despite elevated concentrations in some patients, no clear signs of toxicity were observed, suggesting that combining these anesthetics may not be as safe as assumed.

Introduction: The cause of postoperative delirium is unknown, but it is thought to result at least in part from inflammation. Metformin, besides its hypoglycemic properties, demonstrates anti-inflammatory effects systemically and in the brain. We tested the primary hypothesis that chronic metformin use in adults with type 2 diabetes is associated with less delirium during the first 5 days after major noncardiac surgery.

Background: The smallest meaningful improvement in pain scores (minimal clinically important difference [MCID]) after an analgesic intervention is essential information when both interpreting published data and designing a clinical trial. However, limited information is available for patients with chronic pain conditions, and what is published is derived from studies involving pharmacologic and psychological interventions. We here calculate these values based on data collected from 144 participants of a previously published multicenter clinical trial investigating the effects of a single treatment with percutaneous cryoneurolysis.

Background: Administration of cholinesterase inhibitors in combination with anticholinergic drugs for reversal of neuromuscular blocks may precipitate delirium through impairment of central cholinergic transmission, which could be avoided by using sugammadex. Therefore, we tested the primary hypothesis that postoperative delirium is less common when neuromuscular block is reversed with sugammadex than with neostigmine combined with glycopyrrolate or atropine.

Methods: We conducted a single-center retrospective cohort study, analyzing all adult patients having general anesthesia for noncardiac surgery who received neostigmine or sugammadex from January 2016 to March 2022.
