Introduction: Maternal epilepsy is a critical condition that can significantly affect mothers and fetuses. Notably, the admission of a laboring mother with uncontrolled refractory status epilepticus (RSE) to the operating room presents a challenging scenario for anesthesiologists.

The Main Symptoms Of The Patient And The Important Clinical Findings: A 30-year-old primigravida was transferred to the operating room for an emergency cesarean section.

Most anesthetics reduce cardiac functions and lower blood pressure (BP), potentially causing excessive BP reduction in dehydrated patients or those with heart conditions, such as coronary artery disease (CAD). Considering the increased prevalence of cardiovascular disease with age, anesthesiologists must be cautious about BP reduction during general anesthesia in older adults. In the present case, a 76-year-old male patient with undiagnosed CAD in a hypovolemic state experienced a significant drop in systolic BP to the fifties during propofol and sevoflurane anesthesia.

Background: Postoperative nausea and vomiting (PONV) is a common complication of laparoscopic cholecystectomy. Although PONV is usually mild, severe thing can delay recovery and prolong hospitalization. We aimed to investigate the effects of ramosetron and esmolol, alone and in combination, on PONV, and pain.

Spinal intradural hematoma (SIH) is a rare condition which can cause neurological sequelae such as permanent motor weakness and sensory loss in the lower extremities. Herein, we describe a case of SIH following spinal anesthesia. The patient was a 30-year-old man who underwent treatment for accessory navicular syndrome at our department.

Intraoperative hypoxia occurs in approximately 6.8% of surgeries and requires appropriate management to avoid poor outcomes, such as increased mortality or extended hospitalization. Hypoxia can be caused by a variety of factors, including laryngospasm, inhalational anesthetics, and surgery for abdominal pathology or hip fractures.

Article Synopsis
  • A 71-year-old man had a serious liver issue with symptoms like fever and abdominal pain, and doctors thought it might be liver cancer at first.
  • After tests showed some problems in his liver, doctors treated him with antibiotics and then did surgery, discovering he had a pyogenic liver abscess (PLA) that had burst.
  • The patient got better, stayed in the hospital for 13 days, and later check-ups showed he was completely healthy again, highlighting the importance of careful diagnosis and treatment.

Background: Lightwand is a convenient tool that can be used instead of a laryngoscope for intubation. Tracheal intubation causes direct stimulation of the larynx, drastically increasing hemodynamic values including blood pressure and heart rate. This study aims to identify the effect of different doses of esmolol on hemodynamic changes during lightwand intubation.

Introduction: Patients with motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), have higher sensitivity to nondepolarizing neuromuscular blocking agents (NMBAs) and are at higher risk for a residual block. For this reason, the use of NMBAs such as rocuronium has been limited owing to the delayed reversal of muscle relaxation. It was recently reported that rapid and effective reversal of muscle relaxation occurs when sugammadex, a muscle relaxant reversal drug, is administered to patients in ALS with rocuronium-induced muscle relaxation.

Background: Sevoflurane is widely used to anesthetize children because of its rapid action with minimal irritation of the airways. However, there is a high risk of agitation after emergence from anesthesia. Strabismus surgery, in particular, can trigger agitation because patients have their eyes covered in the postoperative period.

Rationale: Variant angina is characterized by coronary artery spasm irrespective of the presence of fixed stenotic coronary lesions. Perioperative coronary artery spasm may be induced by the supersensitivity of vascular smooth muscle cells caused by various stimuli, including stimulation of the parasympathetic nervous system.

Patient Concerns: A 57-year-old male patient was undergoing arthroscopic rotator cuff repair under combined interscalene brachial plexus block and general anesthesia in the lateral decubitus position.

Purpose: This study set out to identify the association between the intraperitoneal CO concentrations and postoperative pain by dividing the participants into a control group and 2 experimental groups receiving irrigation (1 L and 2 L), and directly measuring their intraperitoneal CO concentrations with a CO gas detector.

Methods: A total of 101 patients, American Society of Anesthesiologists physical status classification I and II patients aged 18-65 years were enrolled in the study. Group 1 did not receive irrigation with normal saline, while groups 2 and 3 were administered irrigation with 1 L and 2 L of normal saline, respectively, after laparoscopic cholecystectomy.

Introduction: Anesthetic management of patients with Duchenne muscular dystrophy (DMD) is complicated because these patients are more sensitive to nondepolarizing neuromuscular blocking agents (NMBAs) and are vulnerable to postoperative complications, such as postoperative residual curarization and respiratory failure. Sugammadex is a new reversal agent for aminosteroidal NMBAs, but its safety in children is controversial.

Clinical Features: An 11-year-old boy with DMD underwent general anesthesia for a percutaneous nephrolithotomy.

Background: Oxycodone, a semisynthetic thebaine derivative opioid, is widely used for the relief of moderate to severe pain. The aim of this study was to compare the efficacy and side effects of oxycodone and fentanyl in the management of postoperative pain by intravenous patient-controlled analgesia (IV-PCA) in patients who underwent laparoscopic supracervical hysterectomy (LSH).

Methods: The 127 patients were randomized to postoperative pain treatment with either oxycodone (n = 64, group O) or fentanyl group (n = 63, group F).

Purpose: Transient Horner's syndrome is an uncommon complication of epidural anesthesia, though its exact incidence in thoracic epidural anesthesia is not clear. Therefore, this study prospectively evaluated the incidence of Horner's syndrome after thoracic epidural anesthesia for mastectomy.

Methods: Patients scheduled for mastectomy, with or without breast reconstruction, were enrolled in this prospective observational study from September 2010 to December 2013.

Background: The opioid sparing effect of low dose ketamine is influenced by bolus dose, infusion rate, duration of infusion, and differences in the intensity of postoperative pain. In this study, we investigated the opioid sparing effect of low dose ketamine in patients with intravenous patient-controlled analgesia (PCA) using fentanyl after lumbar spinal fusion surgery, which can cause severe postoperative pain.

Methods: Sixty patients scheduled for elective lumbar spinal fusion surgery were randomly assigned to receive one of three study medications (K1 group: ketamine infusion of 1 µg/kg/min following bolus 0.

Background: Hypercapnia augments cardiac output and can initiate a sympathetically mediated release of catecholamines to increase cardiac output. Many studies of hemodynamic changes by hypercapnia under general anesthesia with inhalation anesthetics besides sevoflurane. This study examined the hemodynamic changes by increasing end-tidal carbon dioxide (EtCO2) under sevoflurane-N2O anesthesia.
