Preoperative elevated FDP may predict severe intraoperative hypotension after dural opening during decompressive craniectomy of traumatic brain injury.

Purpose: Coagulation disorder and intraoperative hypotension are representative complications of traumatic brain injury which cause worse perioperative outcome. The aim of this study was to survey the relation of coagulation disorder and intraoperative hypotension (IH) during decompressive craniectomy.

Method: Patients who underwent emergency decompressive craniectomy due to traumatic brain injury were retrospectively surveyed.

[Simple Formula to Predict Residual Amount of Continuously Infused Rocuronium in the Body].

Background: When antagonism is performed using sugammadex after continuous infusion of rocuronium, if the total amount of residual rocuronium can be esti- mated prior to performing antagonism, antagonism without excess or deficiency of sugammadex will be made possible. We therefore prepared a simple formula to predict residual amount of rocuronium in the body, which can be easily applied in clinical setting, and veri- fied it using Tivatrainer©.

Methods: 1.

Petechial and subcutaneous hemorrhage with blister formations in right upper extremity during cardiopulmonary bypass by axillary artery cannulation.

A 72-year-old man underwent aortic valve replacement and coronary artery bypass graft using cardiopulmonary bypass with right axillary artery cannulation. After undraping, petechial and subcutaneous hemorrhage with blister formations were found in right upper extremity. Axillary artery cannula was considered to compress right subclavian and disturb venous return in the right subclavian vein, which caused an acute compartment syndrome during cardiopulmary bypass.

Analysis of prehospital endotracheal intubation performed by emergency physicians: retrospective survey of a single emergency medical center in Japan.

Objectives: Advanced airway management in the prehospital setting is a serious issue in Japan because emergency medical technicians are not authorized to perform such management, whereas physicians-who are authorized to perform advanced airway management-do not usually engage in prehospital emergency medical activity. The purpose of this investigation was to investigate the success rate for endotracheal intubation (ETI) procedures and other methods of airway management employed by physicians in the prehospital setting in a single institution, as well as to examine the risk factors associated with difficult or failed endotracheal intubation (D/F ETI).

Methods: We performed a retrospective survey of patients treated in the prehospital setting by emergency physicians of the Hyogo Emergency Medical Center from 2004 to 2011.

[Difficult mask ventilation and tracheal intubation in a patient with Hutchinson-Gilford syndrome].

We report a case of difficult ventilation and tracheal intubation in a 18-year-old woman with Hutchinson-Gilford syndrome. She was diagnosed with osteosarcoma in the right tibia and thyroid cancer. She was scheduled for two operations under general anesthesia for the bone tumor and the thyroid.

[Case of postoperative paraplegia caused by idiopathic spinal cord infarction in a young male patient].

We report a case of spinal cord infarction in a 20-year-old man, who underwent abdominal surgery under general anesthesia combined with epidural anesthesia. The patient was a healthy young man with no medical history. After the operation, he complained of weakness and sensory blockade of both legs.

[Management for the removal of dopamin-secreting pheochromocytoma].

Incidence of dopamin-secreting pheochromocytoma is very rare. We reported managment of anesthesia for the removal of dopamin-secreting pheochromocytoma. A 46-year-old woman was diagnosed with pheochromocytoma, but lacking clinical symptoms.

[Management of one lung ventilation with bronchial blocker catheter for a patient with tracheobronchopathia osteochondroplastica].

Tracheobronchopathia osteochondroplastica is a rare benign disease, with difficult airway for intubation because the trachea and bronchia are narrow and transformed. We experienced one lung ventilation for a patient with the lung cancer associated with the tracheobronchopathia osteochondroplastica. The Coopdech bronchial blocker is a device for one lung ventilation.

[Management of maternal tetanus contracted by an obstetric procedure].

A 34-year-old woman from the Philippines showed difficulty in opening the mouth. She had no wounds in the last one mouth, but was treated with an obstetric procedure after stillbirth 16 days before in the Philippines. She showed trismus, rigidity and muscle pain, but no muscle spasms, dyspnea and autonomic dysfunction.

[Pneumothorax during esophageal endoscopic mucosal resection].

We report a case of pneumothorax occurring during esophageal endoscopic mucosal resection (EEMR). A 53-year-old man with early esophageal carcinoma was scheduled for EEMR under general anesthesia with artificial ventilation. During the operation, arterial oxygen saturation measured by pulse oximeter suddenly decreased from 99% to 84%, and airway pressure increased from 15 cmH2O to 25 cmH2O.

[Tracheal intubation for two patients with lingual tonsil hyperplasia and prospect of difficult airway management].

Lingual tonsil hyperplasia is rare, but may cause difficult or inpossible tracheal intubation. We experienced two cases of tracheal intubation for lingual tonsil hyperplasia. A 71-yr-old man was scheduled for resection and biopsy of symptomatic hypertrophied lingual tonsils.
