Decay of counterflow He II turbulence in a finite channel: possibility of missing links between classical and quantum turbulence.

Decay of He II counterflow turbulence generated by applying a heat pulse to the closed end of a circular channel is investigated using second sound attenuation. Several orders of magnitude of decaying vortex line density display various regimes, starting with the inverse time decay predicted by Vinen towards distinct classical t(-3/2) power law occurring after saturation of the energy containing length scale by the size of the channel. The decaying counterflow turbulence displays a surprisingly close resemblance to recently reported decaying grid turbulence in He II, and both of them appear closely linked to classical grid generated turbulence.

[Anesthesia in percutaneous extraction of concretions from the kidney].

The authors discuss the problem of the most suitable anaesthesia for percutaneous extraction of renal concrements. Based on 203 anaesthesias, they compare the combination of local anaesthesia with intravenous administration of ketamine with a tranquilizer, local anaesthesia with administration of phentanyl and a tranquillizer and local anesthesia with phentanyl and a analgetic-spasmolytic mixture. In the great majority of patients they prefer a combination of local anaesthesia and continuous administration of phentanyl and fractionated administration of an analgetic-spasmolytic mixture.

[Percutaneous extraction of concretions from the kidney].

The authors submit a report on 225 patients operated by the percutaneous approach on the kidney during the period between March 1985 and February 1987. From 231 operations on account of lithiasis concrements were removed in 94.8%. No major complications were observed. The mean period which elapsed from operation to discharge was 8 days in one-stage operations and 19 days in multiple-stage operations. The authors discuss the indications and some technical conditions of the method.

The obturator nerve block. Preventing damage of the bladder wall during transurethral surgery.

During transurethral electroresection in the posterolateral bladder neck, trigone and posterior urethra, unintentional contractions of the thigh-adductor muscles may occur due to irritation of the obturator nerve. The sudden displacement of the bladder wall against the cutting loop may cause a perforation of the bladder. The authors describe the topographic relation of the bladder wall to the passage of the obturator nerve in the minor pelvis. The technique of obturator nerve block by local anaesthesia is described and its efficacy is demonstrated in 21 patients.
