Pre anesthesia

BACKGROUND: Most preschool children are distressed during anesthesia induction. While current pharmacological methods are useful, there is a need for further optimization to an "ideal" standard. Remimazolam is an ultra-short-acting benzodiazepine, and intranasal remimazolam for pre-induction sedation may be promising. METHODS: This study included 32 preschool children who underwent short and minor surgery between October 2022 and January 2023. After pretreatment with lidocaine, remimazolam was administered to both nostrils using a mucosal atomizer device...

BACKGROUND: Approximately 10% of intraoperative cholangiograms identify choledocholithiasis (CDL), stones in the common bile duct. Choledocholithiasis management options include endoscopic retrograde cholangiopancreatography (ERCP) followed by cholecystectomy, laparoscopic cholecystectomy (LC) followed by ERCP (LC + ERCP), cholecystectomy with open common bile duct exploration, or laparoscopic cholecystectomy with laparoscopic common bile duct exploration (LC + LCBDE). The goal of these interventions is to clear the obstruction from CDL...

OBJECTIVE: Percutaneous CT-guided radiofrequency ablation (CT-RFA) is a widely accepted procedure for treatment of osteoid osteomas. However, the application of CT-RFA was restricted as a result of some drawbacks, such as radiation exposure, and inconvenience in general anesthesia. The primary aim of this study is to evaluate the safety and efficacy of intra-operative TiRobot-assisted percutaneous RFA of osteoid osteomas. METHODS: We retrospectively reviewed 21 medical files of patients who were treated with percutaneous RFA of osteoid osteomas guided by the TiRobot system in our institution between March 2021 and April 2022...

BACKGROUND: Most anesthesia providers experience an adverse event during their training or career. Limited evidence suggests skilled peer support programs (SPSPs) reduce initial distress and support adaptive functioning and coping. This study evaluated second victim perceptions of a voluntary SPSP. METHODS: An SPSP was developed and implemented for all clinical and administrative personnel in the Department of Anesthesiology and Perioperative Medicine in three hospitals and six outpatient surgery centers in December 2017...

INTRODUCTION: Skeletal muscle relaxants have previously not been examined in multimodal anesthesia regimens following joint arthroplasty. We sought to evaluate cyclobenzaprine's effect on postoperative opioid consumption as well as surgical recovery following joint arthroplasty. MATERIALS AND METHODS: In this retrospective cohort study, 471 patients undergoing 554 joint arthroplasty procedures were evaluated. Patients were divided into cohorts who did and did not receive cyclobenzaprine postoperatively, and postoperative opioid consumption and functional recovery measures were recorded in each cohort...

INTRODUCTION: Rural patients face barriers to accessing surgical care and often need to travel long distance for pre- or post-surgical consultations. Although adaptation to the COVID-19 pandemic has demonstrated the efficacy of virtual care, there is minimal data available to evaluate patient satisfaction with this modality and consequent health service utilization if virtual services are not available. METHODS: An online survey was conducted with participants living in rural British Columbia, Canada who had undergone surgery within 12 months of data collection and had either virtual or face-to-face pre- or post-surgical consultations...

Neuromyelitis optica (NMO), also known as Devic disease, poses unique challenges in obstetrical anesthesia, with limited research available. This case report presents the anesthetic management of a 43-year-old gravida 2 para 1 (G2P1) woman with NMO undergoing labor induction at 39 weeks of gestation. Having received uneventful epidural labor analgesia in her first pregnancy, she faced the delicate decision of neuraxial anesthesia in light of her NMO diagnosis, which was made following her initial pregnancy...

A breastfeeding 29-year-old woman who gave birth to her first child three months ago presented at the family doctor's appointment with a diverse array of symptoms, including vertigo, blurred vision, right lower limb weakness, and abdominal allodynia. She has a history of obesity and anxiety. The patient had a pre-pregnancy history of several visits to the family doctor. She takes folic acid, vitamin B12, iodine, and omega-3 supplements. The diverse symptomatology, the patient's insistence on seeking medical care, and the history of anxiety pose significant hurdles in arriving at a timely diagnosis...

This case report underscores the effective implementation of a delivery plan for a pregnant patient, focusing on a successful case study where a cesarean section, preceded by the pre-treatment of intravenous plasma-derived C1 inhibitor, resulted in the delivery of a healthy baby. The proposed delivery plan offers a systematic approach to managing hereditary angioedema during pregnancy. It recommends opting for delivery at an academic center equipped with high-risk obstetric care, obstetric anesthesia, and a level 4 Neonatal Intensive Care Unit...

Therefore, we intended to investigate the impact of the American Society of Anesthesiologist (ASA) classification and intraoperative hemodynamic instability on non-surgical complications following orthopedic surgery. (2) Methods: We collected data on 6478 patients, with a mean age of 57.3 ± 16, who underwent orthopedic surgeries between 2018 and 2020...

Background : The injection of local anesthetics is the procedure that still causes the most fear and anxiety in a dental session; to minimize this problem, we can use topical anesthesia. The aim of this study is to analyze the tolerability and the clinical efficacy in the control of pain, during the subsequent injection of the local anesthetic, of an experimental anesthetic patch with a new formulation, which was previously tested in gel formula. Methods : A total of 150 children, aged 4 to 9 years, were included in the study...

Background: The use of laryngeal masks in the surgical treatment of infantile lacrimal duct stenosis is controversial due to the potential risk of aspiration. Aims: This study investigates airway procedures in children aged <6 years for surgery of lacrimal duct stenosis in a tertiary care university hospital. Methods: After institutional approval, airway procedures, duration of anesthesiological measures, and airway-related complications were retrospectively analyzed. Patients were divided into two groups according to the airway procedures used (endotracheal tube [ET] vs...

Controlling preoperative anxiety is necessary in pediatric patients to avoid adverse effects such as emergence delirium, behavioral problems, post-traumatic stress disorder, anxiety prior to future procedures, and increased analgesic doses in the recovery room. Some patients, especially ones with behavioral issues, have a difficult time arriving at the hospital. Medications given at home can be helpful. We describe a case series of six patients who received pre-admission oral clonidine prior to arrival to the hospital...

OBJECTIVE: Laparoscopic cholecystectomy (LC), despite its minimally invasive nature, requires effective control of post-operative pain. The use of local anesthetics (LA) has been studied, but the level of evidence is low, and there is little information on important parameters such as health-related quality of life (HRQoL) or return to work. The objective of the study was to evaluate the efficacy of 0.50% levobupivacaine infiltration of incisional sites in reducing POP after LC. METHODS: This was a prospective, randomized, double-blind study...

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)...

Airway management is a vital part of anesthesia practices, intensive care units, and emergency departments, and a proper pre-operative assessment can guide clinicians' plans for securing an airway. Complex airway assessment has recently been at the forefront of anesthesia research, with a substantial increase in annual publications during the last 20 years. In this paper, we provide an extensive overview of the literature connected with pre-operative airway evaluation procedures, ranging from essential bedside physical examinations to advanced imaging techniques such as ultrasound (US), radiography, computed tomography (CT), and magnetic resonance imaging (MRI)...
