[Assessment of vigilance for patients with sleep disordered breathing].

Objective: Assessment of vigilance for patients with sleep disordered breathing.

Methods: Vigilance of the patients referred to sleep study for suspected sleep disorders was evaluated prospectively by a computerized driving simulator SteerClear before (evening) and after (next morning) nocturnal sleep study. The vigilance was quantified by means of the averaged percentages of obstacle hitting made during the evening and the morning driving test, abbreviated as %Hm.

[Study on evaluation of fetal scalp tissue pH value during labor].

Objective: To assess the predictive value of serial monitoring fetal scalp tissue pH value (tpH) during labor.

Method: Fifty two primipara with singleton and cephalic presentation were recruited during their active phase of labor after rupture of membrane. Their fetal scalp tpH were determined by a new type of alloy pH spiral electrode and pH-LS-1 sensor.

Epiphyseal lengthening operation--an improved technique.

An improved method of epiphyseal lengthening operation and subsequent outer fixation are presented on the basis of experience in 30 cases. The operative technique is described in detail, including the different options of separative traction and osteotomy at subtrochanteric, distal part of the upper femur and lower tibial levels. The physiological and histological research concerning this method is discussed.

[Effects of indomethacin in guinea pig cochlea: researches on audiology, morphology and cochlear blood flow].

Prostaglandins are known to be widely distributed in mammal tissues with diverse and potent biological activities. Indomethacin is a well-known cyclooxygenase inhibitor of prostaglandin synthesis. However, no paper appeared in the literature with regard to the effects of indomethacin on inner ear hearing function and cochlear lateral wall blood flow (LWBF).

[Prediction of infection complicating premature rupture of the membranes by monitoring fetal breathing movement with ultrasound].

Modified Vintzileos monitoring skill and scoring criteria of fetal biophysical profile (FBP), were used in assaying 48 patients with premature rupture of the membranes (PROM). The last determination before delivery was compared with the outcome of pregnancy. The results showed: (1) The infection rate in patients with low biophysical score (less than or equal to 7) was significantly higher than that of high score (greater than 7); (2) The infection rate in patients presenting fetal breathing movements (FBM) of greater than or equal to 60 sec.
