Clinical Trial Controlled Clinical TrialA pilot/introducer needle for central vein cannulation.
A kit for safe and easy insertion of a central vein cannula was devised. A small gauge (22 gauge) metal pilot needle was equipped with a Y-shaped hub which had a side-port to accept a small gauge (0.46 mm) Seldinger guide wire. Once the needle reached the vein, guidewire was threaded in through the side-port. ⋯ Each method was used on 20 patients, for total of 60 patients, with a high success rate. Less than 3 minutes were required from puncture to catheter insertion. No serious complications were encountered.

Case Reports Clinical Trial Controlled Clinical TrialUse of cultured human epidermal allografts for the treatment of extensive partial thickness scald burn in children.
In spite of recent progress in burn treatment, the early surgical therapy of partial thickness scald burns in children is still controversial. Early tangential excisions is not easily applicable for these patients because of difficulties in determination of the burn depth and probable physiological derangement after surgery. Hypertrophic scar formation and wound contraction after meshed autografts are other limitations. ⋯ Allografting of the cultured epidermis without surgical excision apparently promoted the rapid regeneration of the partial thickness burns. Procedural complications did not occur. Cultured allografts should be used as an effective and safe biological dressing for partial thickness scald burns in children.

Measurement of functional residual capacity and pulmonary carbon monoxide diffusing capacity during mechanical ventilation with PEEP.
First, our new simplified method to measure FRC and DLCO simultaneously during mechanical ventilation was described in detail. Secondly, we applied the method to ARDS patients and observed the effects of PEEP on arterial blood gases (ABGs), FRC and DLCO of these patients. ⋯ DLCO/FRC remained unchanged, although DLCO increased with PEEP. We concluded that the dissociation of FRC and ABG data in a group of patients could be caused by wasted ventilation which might be attributed to VA/Q unevenness.

Effects of inspiratory pressure oscillation on pulmonary gas exchange and circulatory functions in anesthetized, mechanically ventilated dogs.
Anesthetized, mechanically ventilated dogs were used to study the effects of inspiratory pressure oscillation on gas exchange. Respiratory failure was induced in dogs artificially, changing either tidal volume or ventilatory rate. Pressure oscillation of approximately 2 Hz with amplitudes of 2 to 7 cmH2O was applied on the inspiratory phase of mechanical ventilation. ⋯ The oscillated ventilation while breathing He-O2 and SF6-O2 showed no consistent difference in the effects on gas exchange. It can be concluded that simple pressure oscillation improves gas mixing in the lungs and may be applied to respiratory care. However the mechanism remains to be elucidated.
