Comparative Study
[Pentax-AWS improves laryngeal view compared with Macintosh blade during laryngoscopy and facilitates easier intubation].
The PENTAX-AWS (AWS), combined with PBLADE is a novel tracheal intubation device which allows indirect visualization of the vocal cords without the alignment of the oral, pharyngeal axes required for direct laryngoscopy. Intubation procedure can be monitored on a built-in CCD monitor. ⋯ We conclude that the PENTAX-AWS provides a better laryngeal view than the Macintosh laryngoscope and facilitates easier intubation under vision in a higher proportion of patients.

Intracranial subdural hematoma (SDH) following dural puncture (DP) is a life-threatening complication. However, the characteristics and prognosis are little-known. ⋯ Seventy per cent of SDH occured following anesthesia related procedures. Most of them had an onset within one month after DP The prognosis was relatively good as long as SDH could be diagnosed at its early stage. It was necessary to observe the disappearance of postural headache and associated symptoms carefully to avoid delayed diagnosis.

Comparative Study
[Leakage in anesthesia circuits--a comparison between 1998 and 2005 investigations].
We checked for the occurrence of any leakage in an anesthesia circuit to estimate the present situation of airtightness of an anesthesia circuit in 55 anesthesia machines at various medical institutions in Okinawa. ⋯ Most instances of leakage of the above described anesthesia circuits were identified in the corrugated breathing tube and canister. As a result of our findings, we strongly recommend that these parts be checked very carefully during pre-anesthetic leak tests.

Thermometers widely used intraoperatively are invasive and non-hygienic. We developed an earphone-type infrared tympanic thermometer and evaluated its usefulness as a core temperature monitor. ⋯ The earphone-type tympanic thermometer can be used in a clinical setting as a reliable core temperature monitor.

A 23-year-old man with xeroderma pigmentosum underwent laparoscopic cholecystectomy. He experienced transient worsening of the neurological symptom after anesthesia with volatile agents in the previous surgery. ⋯ From these two anesthesia experiences in one patient, we suggest that TIVA is more appropriate than anesthesia with volatile agents as a method for general anesthesia for xeroderma pigmentosum patients. Minimum usage of muscle relaxants under the monitoring of neuromuscular blockade is also recommended, since xeroderma pigmentosum patients are sensitive to muscle relaxants due to the neuronal dysfunction and muscle
