A 54-year-old man had emergency laparoscopic chelecystectomy for acute cholecystitis. General inflammatory change (CRP 26.6 mg x dl(-1), WBC 26,800) was noted preoperatively. Anesthesia was induced with propofol and remifentanil and maintained with sevoflurane in oxygen and remifentanil. Operation was performed uneventfully within 128 min. At the end of the surgery, 0.1 mg of fentanyl was administrated. After confirming adequate respiration and oxygenation, endotracheal tube was removed. At that period, hypertension (SBP 220 mmHg) and tachycardia (HR 122 beats x min(-1)) developed. Soon thereafter, he became agitated and complained of dyspnea with desaturation (Spo2 < 70%). After reintubation, massive pinkish babbly secretion flowed out from the endotracheal tube. Chest X-ray revealed diffuse bilateral infiltration of the lungs without cardiomegaly. He was transferred to the intensive care unit for mechanical ventilation. His condition improved progressively and was extubated on the POD 6. The cause of pulmonary edema is thought to be profound centralization of circulating volume associated with catecholamine-induced vasoconstriction due to rapid disappearance of remifentanil effect. Adequate analgesia is necessary during remifentanil-based anesthesia especially in patients suffering from general inflammatory changes.

Objective: In the context of acute cardiogenic pulmonary edema (ACPE), a frequently encountered medical emergency associated with high early mortality rates, there is a need to predict short-term outcomes for risk stratification.Our aim was to derive and validate a model, a simple clinical scoring system using baseline vital signs, clinical and presenting characteristics, and readily available laboratory tests, that allows accurate prediction of short-term mortality in individuals experiencing ACPE.
Methods: This retrospective cohort study included 1088 patients with ACPE from six health centers.

High altitude characterized by the low partial pressure of the oxygen is a life-threatening condition that contributes to the development of acute pulmonary edema and hypoxic lung injury. In this study, we aimed to investigate the contribution of some inflammatory and oxidative stress markers along with antioxidant system enzymes in the pathogenesis of HAPE (high-altitude pulmonary edema) formation. We incorporated the study on 42 male rats to unravel the role of mast cells (MCs) and TNF-α in the lung after the effect of acute hypobaric hypoxia.

Importance: Lung ultrasound (LUS) aids in the diagnosis of patients with dyspnea, including those with cardiogenic pulmonary edema, but requires technical proficiency for image acquisition. Previous research has demonstrated the effectiveness of artificial intelligence (AI) in guiding novice users to acquire high-quality cardiac ultrasound images, suggesting its potential for broader use in LUS.
Objective: To evaluate the ability of AI to guide acquisition of diagnostic-quality LUS images by trained health care professionals (THCPs).

Anterior cord syndrome is a rare yet critical neurological condition that poses significant challenges in clinical management. We present the case of a 71-year-old male with a medical history of hypertension, uncontrolled type II diabetes mellitus, hypothyroidism, and end-stage renal disease requiring dialysis who presented to the emergency department with complaints of chills, back pain, abdominal pain, and vomiting episodes. Based on the severity of the patient's illness, it was decided that inpatient admission would be best.

Key Clinical Message: Although the symptoms of accidental chlorine inhalation are typically mild, severe exposure can result in acute respiratory distress syndrome (ARDS). We present a case of pediatric ARDS due to chlorine exposure in which lung lavage and exogenous surfactant were successful in avoiding more invasive and costly treatments.
Abstract: Chlorine inhalation as a result of swimming pool chlorination accidents is relatively common.
