Cardiopulmonary arrest caused by nafamostat mesylate during hemodialysis.

Dialysis-related adverse reactions can be serious and difficult to predict. In our case, nafamostat mesylate (NM) was thought to be the cause of cardiopulmonary arrest (CPA) due to NM-induced anaphylaxis but was not reflected in the allergy tests. Rare but life-threatening drawbacks occur immediately after hemodialysis initiation.

Isolated tricuspid valve infective endocarditis with multiple septic pulmonary emboli in a patient with atopic dermatitis.

Multiple lung nodules in atopic dermatitis patients may reflect infective endocarditis. Our case underlines the importance of potentially severe infections due to staphylococci associated with atopic dermatitis.

Characteristics of COVID-19 patients admitted into two hospitals in sapporo, Japan: Analyses and insights from two outbreak waves.

Background: Coronavirus disease (COVID-19) emerged in January 2020 in Sapporo city, and the outbreak has shown two peaks.

Methods: A total of 260 COVID-19 patients were enrolled and categorized into three groups according to the pandemic pattern, jobs and situation, and disease severity. We compared clinical characteristics according to these categories.

Enlargement of Intrathoracic Goiter with Unilateral Phrenic Nerve Paralysis Leading to Cardiopulmonary Arrest.

As an intrathoracic goiter expands, it causes airway stenosis and phrenic nerve paralysis, and slight respiratory stimuli can trigger sudden life-threatening hypoventilation. A 78-year-old obese woman with a large intrathoracic goiter was found unconscious with agonal breathing in her room early in the morning. Cardiopulmonary resuscitation restored spontaneous circulation.

Delayed diagnosis of traumatic ventricular septal perforation in penetrating chest injury: hematoma formation in the ventricular septum in CT suggests perforation.

Background: Ventricular septal perforation (VSP) can be caused by a penetrating cardiac injury. Diagnosis of VSP tends to be delayed because a shunt might not be detected by color flow Doppler at an early stage following injury.

Case Presentation: A 60-year-old man with depression was admitted to the emergency center after a knife injury in the chest.

Effects of epinephrine administration in out-of-hospital cardiac arrest based on a propensity analysis.

Background: Epinephrine administration has been advocated for cardiopulmonary resuscitation (CPR) for decades. Despite the fact that epinephrine administration during CPR is internationally accepted, the effects of the prehospital epinephrine administration still remain controversial. We investigated the effects of epinephrine administration on patients with out-of-hospital cardiac arrest based on a propensity analysis with regard to the 'CPR time'.

[Evaluation of autologous transfusion for radical prostatectomy].

Forty-six radical prostatectomy patients in whom an autologous transfusion had been performed in our hospital were studied retrospectively. Preoperative autologous donation (PAD), erythropoietin (EPO) administration and acute normovolemic hemodilution (ANH) were used for autologous transfusion. Red blood cell volume lost during hospitalization was calculated as 1329 +/- 493 ml.

[Perioperative complications of patients with cementless femoral head replacement].

Background: Studies have shown that use of cement is a risk factor for fat embolism in elderly patients with femoral neck fracture. We investigated the usefulness of the cementless femoral head replacement technique.

Methods: A retrospective study of 58 patients who had undergone this technique between January 1995 and May 2001 was conducted.

[Anesthetic management for a radical operation in an infant with cloacal exstrophy].

We report the anesthetic management for a radical operation in an infant with cloacal exstrophy. Diagnosis of cloacal exstrophy with meningocele was made at the 26th week of gestation. Cesarian section was performed under general anesthesia in order to keep the infant in a state of apnea to prevent aerophagia, the so-called "sleeping baby", at the 38th week of gestation.

[Myoglobinemia in a patient due to positioning during nephrectomy].

We report a case of myoglobinemia observed in the postoperative period due to forced positioning during nephrectomy. A 32-year-old male, weighing 93 kg, underwent the left nephrectomy due to renal cell carcinoma under general anesthesia with epidural block. The operation was performed uneventfully but he complained of severe pain in his right hip immediately after the recovery from anesthesia.

Effect of the lithotomy position on spinal anesthesia with hyperbaric tetracaine.

This study was performed to determine the effects of lithotomy position on the spread of analgesia and hemodynamics following spinal anesthesia with 0.5% hyperbaric tetracaine. Thirty patients who underwent hysterectomy due to myoma uteri were studied.
