[Anesthesia and the postoperative period in non-urgent tracheal surgery. Apropos of 36 patients].

The authors report 36 cases of resection and suture for stenosis or tumour of the trachea and give details of their technique of anaesthesia, the post-operative follow-up and their results. The development of fiber endoscopy and simplification of intubation, increases the security of the patient, facilitates the task of the anaesthetist and thus improves greatly the operative conditions and post-operative period.

Diffraction-like effects in a highly concentrated W/O emulsion: a PFG NMR study.

Diffraction-like effects have been observed by applying pulsed field gradient (PFG) nuclear magnetic resonance (NMR) to a highly concentrated water-in-oil (W/O) emulsion, made up of the nonionic surfactant C12E4 [CH3(CH2)11(OCH2CH2)4OH], n-decane, and brine [1 wt% NaCl(aq) solution]. The pulsed field gradient NMR data show one pronounced maximum and the shoulder of a second maximum in the attenuation curve of the NMR signal from water, the so-called Bragg interference peaks. From the diffraction-like peaks, the average distance (center to center) between the emulsion droplets can be obtained, in this case related to the average size of an emulsion droplet. Furthermore, we note that the long-term stability of the emulsion can be followed by pulsed field gradient NMR.

Nursing protocol for manipulation of haemodialysis catheters.

This study looked at the incidence of infection complications, in relation to central vein catheterisation as a provisional HD access, by means of the establishment of a nursing protocol for the handling of these catheters. Central vein catheterisation is a classical technique in Nephrology.

[Ciprofloxacin-induced vasculitis with cutaneous and renal involvement].

Quinolone antibiotics are frequently used in the practice of medicine. Nephrotoxic side effects related to the use of quinolones are uncommon. We report a patient in treatment with ciprofloxacin who presented with purpuric skin lesions and alteration of renal function. We review these antibacterial agents with special attention on associated adverse reactions, and present-day experience with the newer quinolone antibiotics.
