[A Case of Epidural Hematoma after Removal of Epidural Catheter in a Patient with Coagulation Disorder].

A 75-year-old man with abdominal aortic aneurysm underwent Y-graft replacement under combination of general anesthesia and epidural anesthesia. Although we inserted an epidural catheter at first attempt from T11-12, nurse cut the epidural catheter accidently. We re-inserted from the same place.

Genome-wide association study identifies candidate loci associated with postoperative fentanyl requirements after laparoscopic-assisted colectomy.

Aims: Opioids are widely used as effective analgesics, but opioid sensitivity is well known to vary widely among individuals and the underlying genetic factors are not fully understood, thus hampering efficient pain treatment. We explored the genetic factors that contribute to individual differences in opioid sensitivity by performing a genome-wide association study.

Methods: We conducted a multistage genome-wide association study in subjects who underwent laparoscopic-assisted colectomy (LAC).

[The SorbaView SHIELD is a Useful Product for Use in Perioperative Management].

Background: We studied the stability of the continuous arterial pressure line (A line) achieved by using a catheter securement device.

Methods: A total of 100 patients requiring an arterial catheter were divided into 2 groups of fixation: (1) fixation achieved by using the SorbaView SHIELD (Centurion Medical Products Corporation, USA) and (2) fixation by using Tegaderm 3 M (TEGADERM 3 M, Japan). We analyzed the stability of the fixation, presence or absence of skin disorders, and the preference by nurses.

[A case of obstruction in the left internal jugular vein which both ultrasound prescan and chest computed tomography could not detect before the insertion of a pulmonary artery catheter].

In a 54-year-old man, at the time of anesthesia administration during the Bentall re-operation, a preoperative ultrasound scan showed right internal jugular vein thrombosis before insertion of a pulmonary artery catheter into the right internal jugular vein. Therefore, we performed the insertion after confirming that the left internal jugular vein was safe via a preoperative ultrasound and chest computed tomography (CT). Although we could insert the catheter sheath, contrast imaging revealed that the pulmonary artery catheter had advanced no further than approximately 15 cm into the left internal jugular vein.

[Successful intubation in a difficult case using an Ambu Laryngeal Mask Angle Type-i, and the ability to pass a gastric tube behind the laryngeal mask].

A 71-year-old male was scheduled for a laparoscopic cholecystectomy. The plan was to intubate him using direct laryngoscopy. After induction of anesthesia and analgesia direct laryngoscopy was performed but it was difficult to get a good view of epiglottis, and at 2nd attempt there was laryngeal edema, which made the procedure more difficult.

[Case of perioperative tracheal laceration by electrocautery].

Although tracheal laceration during surgical procedure is a rare complication, it can be life-threating. Its immediate recognition and treatment are important. A 72-year-old man with aortic valve regurgitation was scheduled for aortic valve replacement.

Early verb learning in 20-month-old Japanese-speaking children.

The present study investigated whether children's representations of morphosyntactic information are abstract enough to guide early verb learning. Using an infant-controlled habituation paradigm with a switch design, Japanese-speaking children aged 1 ; 8 were habituated to two different events in which an object was engaging in an action. Each event was paired with a novel word embedded in a single intransitive verb sentence frame.

Epicardial hematoma and myocardial ischemia following application of Starfish stabilizer: an uncommon complication of the device.

The Starfish heart positioning device allows excellent cardiac positioning and hemodynamic stability during off-pump coronary artery bypass graft surgery. Herein, we present a patient in whom the use of this device caused epicardial hematoma as the result of an injured epicardial vein, an uncommon complication of this device. In this patient, regional left ventricular wall motion abnormality on transesophageal echocardiography and a ST-T change on electrocardiogram occurred secondary to the development of the epicardial hematoma.

Risk factors for the development of reversible psychomotor dysfunction following prolonged isoflurane inhalation in the general intensive care unit.

Study Objective: To identify risk factors for reversible psychomotor dysfunction after prolonged sedation with isoflurane during mechanical ventilation in the intensive care unit (ICU).

Design: Retrospective case series.

Setting: General ICU at Tonami General Hospital.

Can intravenous atropine prevent bradycardia and hypotension during induction of total intravenous anesthesia with propofol and remifentanil?

This study was conducted to examine whether pretreatment with intravenous atropine could prevent bradycardia and hypotension during induction of total intravenous anesthesia with propofol and remifentanil in a prospective randomized placebo-controlled manner. Seventy patients, aged 24-78 years, were randomly divided into two groups, and received 0.5 mg atropine or placebo saline 1 min before induction of intravenous anesthesia with remifentanil at 0.

Suspected recurrent anaphylaxis in different forms during general anesthesia.

We report on a patient who presented with recurrent severe shock during general anesthesia. The patient was a man scheduled for lung surgery whose first attack was a coronary spasm, which was followed by a second shock with severe bronchospasm and hypotension 4 weeks later. An elevated serum tryptase concentration was observed, and subsequent skin testing revealed negative reactions to some drugs administered in this case.

Spread of spinal anesthesia in patients having perianal surgery in the jackknife position: effects of baricity of 0.5% bupivacaine and positioning during and after induction of spinal anesthesia.

Study Objective: To compare the influence of baricity and patient positioning during onset of subarachnoid block in patients placed in the prone, jackknife position with head-down tilt of 15 degrees .

Design: Randomized study.
