Case Reports
[Successful nasal intubation using airway scope with gum elastic bougie in a case of difficult airway].
AWS (Airway Scope, Pentax, Tokyo), a new videolaryngoscope, was originally designed to facilitate oral laryngoscopy and tracheal intubation. We describe a successful case of nasal intubation with a combination of AWS and GEB (gum elastic bougie). A 50-year-old man with a past history of difficult intubation was scheduled to undergo subtotal esophagectomy. ⋯ Oral insertion of AWS showed full view of the glottis and nasal insertion of GEB was easily advanced into the trachea through an endotracheal tube, allowing tracheal intubation while utilizing GEB as a stylet. No complication occured in this case. In conclusion, nasal intubation using AWS combination with GEB is useful for patients with difficult airways and is easy to perform.

Lidocaine is frequently used as a local anesthetic and has very low incidence of serious complications. I report on a case of lidocaine intoxication in a 66-year-old man who presented with seizure and cardiac periarrest following the brachial plexus block with 450 mg of lidocaine. ⋯ Bradycardia and subsequent cardiovascular depression were found 74 minutes after the lidocaine block. The patient was successfully treated with diazepam, atropine sulphate and transcutaneous pacing for each symptom, respectively.

In this decade, the molecular mechanism of sepsis has been strikingly clarified. Especially, the identification of toll-like receptors as the pivotal molecules for the recognition of the stimulation of the inflammatory products of microorganisms has contributed to the elucidation of intracellular signaling pathways which result in severe systemic inflammatory response in sepsis. The production and release of a variety of pro-inflammatory mediators have been found to be associated with severe systemic inflammation and multiple organ dysfunction syndrome (MODS). ⋯ Despite of the advance in the basic research regarding molecular pathophysiology of sepsis, sepsis is still accompanied by high mortality in clinical settings. Almost all clinical trials targeting sepsis-associated mediators have failed, except the substitution therapy of activated protein C. However, further trials based on the basic findings, including the therapies targeting the multiple mediators, will contribute to the improvement of outcome of clinical sepsis. ple organ dysfunction syndrome (MODS), pro-inflammatory mediator, disseminated intravascular coagulopathy (DIC).

We report a case of anaphylactic shock caused by repeated use of aprotinin. Following re-administration of aprotinin at the beginning of repeated mitral valve replacement, the patient fell into shock state probably induced by anaphylactic reactions. Immediately, bispectral index (BIS) decreased from 40 to 5, and near-infrared spectroscopy showed regional tissue oxygen saturation (rSO2) of frontal head decreasing from 64/56% (left/right) to 26/36%. ⋯ After the immediate initiation of cardiopulmonary bypass, the perfusion pressure increased to 40 mmHg, and BIS and frontal rSO2 recovered to 45 and 70/61%, respectively. The patient had no significant neurological sequela after the surgery. We conclude that parallel changes of BIS and frontal rSO2 reflect acute global cerebral ischemia, and these parameters may be useful for decision making in the treatment of shock patients.

Although postoperative femoral neuropathy is an uncommon complication occurring after pelvic surgery, we experienced several cases of femoral nerve palsy in patients after radical prostatectomy. All cases had neither previous vascular nor peripheral nerve disease. To investigate the possible etiology, we compared the difference in age, height, body weight, body mass index (BMI), duration of surgery, and volume of bleeding in patients with or without femoral nerve palsy. ⋯ After these strategies, we found that the frequency of femoral nerve palsy had considerably decreased. Patients received physical therapy and showed nearly total neurological recovery. We report here unusual complication following major pelvic surgery, and discuss the possible etiology and some strategies for prevention of this injury.
