Preoperative NOT Anesthesia

The perioperative neurocognitive disorder (PND) is a severe complication that affects millions of surgical patients each year. Homocysteine (Hcy) is known to increase the risk of developing PND in both young and elderly mice. However, whether Hcy alone can induce cognitive deficits in middle-aged mice (12-month-old), whether exercise can attenuate Hcy-induced hippocampus-related cognitive deficits after surgery through suppressing neuroinflammation, synaptic elimination, and the level of Hcy remains unknown...

Galactose-⍺-1, 3-galactose (alpha-gal) is an oligosaccharide found in mammalian tissues that causes allergic reactions in patients with alpha-gal syndrome (AGS). AGS is a hypersensitivity reaction notable for both immediate and delayed allergic and anaphylactic symptoms. As a tick-based disease, AGS has gained increasing prevalence across the United States and can have a significant influence on which medications are safe for patients. Many medications used within the operating room and intensive care units have inactive ingredients that can be mammalian-derived and therefore should be vetted before administering to patients with AGS...

BACKGROUND: Surgical treatments such as lymphaticovenular anastomosis (LVA) are widely used in addition to conservative treatment of secondary lymphedema. However, their indications and effectiveness for primary lymphedema are unclear. This study aims to objectively demonstrate the effectiveness of LVA for adult-onset primary lymphedema from various perspectives. METHODS: We retrospectively examined patients with primary lower limb lymphedema who underwent LVA between January 2018 and December 2021 and were 21 or older...

PURPOSE: To investigate the association of pre--photorefractive keratectomy Schirmer-1 test value with post--photorefractive keratectomy central corneal epithelial thickness, ocular surface disease index score, and uncorrected distance visual acuity. METHODS: Patients were categorized according to preoperative Schirmer-1 value: the normal Schirmer Group (n=54; Schirmer-1 test value, >10 mm) and the low Schirmer Group (n=52; Schirmer-1 test value, between 6 and 10 mm)...

BACKGROUND: Pulmonary aspiration is a potentially lethal perioperative complication that can be precipitated by gastric insufflation. Face mask ventilation (FMV), a ubiquitous anesthetic procedure, can cause gastric insufflation. FMV with an inspiratory pressure of 15 cm H2O provides the best balance between adequate pulmonary ventilation and a low probability of gastric insufflation. There is no data about the effects of FMV > 120 seconds. OBJECTIVES: To investigate the effect of prolonged FMV on gastric insufflation...

INTRODUCTION: Traumatic mandibular fractures are the most common fractures of the facial region and are associated with loss of neurosensation in the inferior alveolar nerve (IAN). The present study aimed to compare IAN recovery after traumatic mandibular fractures between the open and closed reduction methods. MATERIALS AND METHODS: The study included 90 patients with traumatic mandibular fractures of the body, angle, and symphysis, divided into two groups of 45 patients: group 1 was treated with closed reduction and fixation with rich arch-bar fixation under local anesthesia, and group 2 was treated with open reduction and rigid internal fixation with 2-mm titanium mini plates and monocortical screws (6 mm), and the plate was fixed to the fractured bony fragments...

BACKGROUND: Common peroneal nerve palsy (CPNP) is a rare complication of total knee arthroplasty (TKA). It may lead to impaired function and pain. The purpose of this study was to determine the frequency and outcome of CPNP in a single orthopedic unit and to identify potential risk factors. METHODS: This is a single-center study using the hospital's prospectively collected quality registry. All TKAs from 2002 to 2022 were included and followed up from 3 to 24 months with a follow-up rate of 98...

BACKGROUND: Beta-blocker (BB) therapy plays a central role in the treatment of cardiovascular diseases. An increasing number of patients with cardiovascular diseases undergoe noncardiac surgery, where opioids are an integral part of the anesthesiological management. There is evidence to suggest that short-term intravenous BB therapy may influence perioperative opioid requirements due to an assumed cross-talk between G-protein coupled beta-adrenergic and opioid receptors. Whether chronic BB therapy could also have an influence on perioperative opioid requirements is unclear...

OBJECTIVE: To investigate if preoperative ondansetron reduces postoperative nausea associated with laparoscopic gastropexy and castration in dogs. STUDY DESIGN: Prospective clinical study. ANIMALS: Twenty client-owned, healthy male dogs. METHODS: Dogs were premedicated with dexmedetomidine (2-5 mcg kg-1 ) and methadone (0.2-0.5 mg kg-1 ) intramuscularly. General anesthesia was induced with propofol and maintained with an inhalant anesthetic agent...

Perioperative hypersensitivity reactions vary from mild to potentially fatal anaphylaxis, resulting in significant morbidity and mortality. Most of the perioperative hypersensitivity and allergic reactions are attributed to antibiotics, antiseptic solutions, latex, and opioids. In the current thrust for opioid-free anesthesia, owing to its multiple advantages, paracetamol and nonsteroidal antiinflammatory agents play a significant role in multi-modal pain and inflammatory response management. Nearly nine out of ten individuals experience postoperative pain, one-third experience postoperative nausea and vomiting, and one-fourth experience fever, irrespective of surgery and type of anesthesia, often as an inflammatory response...

BACKGROUND: Modern perioperative guidelines encourage drinking oral carbohydrates 2 h before management. Nevertheless, research on the safety of preoperative carbohydrate drinks, particularly in extremely elderly patients is lacking. We aimed to evaluate the safety of carbohydrate drinks 2 h before surgery in extremely elderly patients (≥ 80 years) using gastric ultrasonography. METHODS: We conducted a randomized prospective comparative study of 70 patients aged over 80 years who were scheduled for total knee arthroplasty, hip fracture or humerus fracture surgery...

INTRODUCTION: Among older adults undergoing surgery, postoperative delirium is the most common complication. Cognitive impairment and dementia are major risk factors for postoperative delirium, yet they are frequently under-recognized. It is well established that applying delirium preventive interventions to at-risk individuals can reduce the likelihood of delirium by up to 40%. The aim of this study was to evaluate how often delirium preventive interventions are missing in patients at risk for delirium due to baseline cognitive impairment...

BACKGROUND: Lipomas are benign and are usually located in subcutaneous tissues. Surgical excision frequently requires an incision equal to the diameter of the lipoma. However, small incisions are more cosmetically pleasing and decrease pain and/or hypoesthesia at the incision. A "fibrous structure" occurs inside the lipoma and is characterized by a low-intensity signal on T1-weighted magnetic resonance images. The "fibrous structure" is actually retaining ligaments with a normal structure that intrudes from the periphery1 ...

BACKGROUND: Primary trigger point deactivation surgery has been successful in reducing or eliminating nerve compression headaches between 79% and 90% of the time. The aim of this review article was to discuss the factors that contribute to index trigger point deactivation surgery failure, the importance of reevaluating trigger points following failure, and the options for secondary surgery. METHODS: A literature search was performed using a combination of keywords involving "chronic headache" and "nerve deactivation surgery," in databases until February 2023...

OBJECTIVE: Compared with fresh frozen plasma (FFP), Omniplasma has been attributed to an increased coagulation potential and an increased fibrinolytic potential. This study aimed to compare Omniplasma and FFP used for cardiopulmonary bypass (CPB) priming regarding the incidence of postoperative thrombotic or hemorrhagic complications and outcomes in pediatric patients undergoing cardiac surgery. DESIGN: A retrospective observational cohort study SETTING: This single-center study was performed at the University Medical Center Groningen...

OBJECTIVE: Evaluation of viscoelastic parameters along with Hct percentages, platelet numbers, and fibrinogen concentrations in healthy dogs undergoing elective stifle arthroscopy and tibial plateau leveling osteotomy (TPLO). These results determine if dogs are in a normal, hypocoagulable, or hypercoagulable state at 4 different time points. ANIMALS: Prospective study of 37 client-owned dogs enrolled between February 2, 2022, and November 10, 2022. METHODS: All dogs received a standardized anesthetic protocol...

BACKGROUND: Percutaneous transforaminal endoscopic decompression (PTED) is an ideal minimally invasive decompression technique for the treatment of lumbar spinal stenosis (LSS) with degenerative lumbar spondylolisthesis (DLS). The posterosuperior region underneath the slipping vertebral body (PRSVB) formed by DLS is an important factor exacerbating LSS in patients. Therefore, the necessity of removing the PRSVB during ventral decompression remains to be discussed. This study aimed to describe the procedure of PTED combined with the removal of the PRSVB and to evaluate the clinical outcomes...

OBJECTIVE: Acute kidney injury (AKI) requiring renal-replacement therapy (RRT) after heart transplantation (OHT) is common and impairs outcomes. This study aimed to identify independent donor and recipient risk factors associated with RRT after OHT. DESIGN: A retrospective data analysis. SETTING: Data were collected from clinical routines in a maximum-care university hospital. PARTICIPANTS: Patients who underwent OHT...

PURPOSE OF REVIEW: There is an increasing awareness of the significance of intraoperative pain during cesarean delivery. Failure of spinal anesthesia for cesarean delivery can occur preoperatively or intraoperatively. Testing of the neuraxial block can identify preoperative failure. Recognition of the risk of high neuraxial block in repeat spinal in case of preoperative failure is important. RECENT FINDING: Knowledge of risk factors for block failure facilitates prevention by selecting the most appropriate neuraxial procedure, adequate intrathecal doses and choice of technique...

BACKGROUND: Total joint arthroplasty (TJA) performed in the ambulatory surgical center (ASC) has been shown to be safe and cost-effective for an expanding cohort of patients. As criteria for TJA in the ASC become less restrictive, data guiding the efficient use of ASC resources are crucial. PURPOSE: We sought to identify factors associated with length of stay in the recovery room after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) performed in the ASC...
