[Study of a protocol of intra-articular analgesia after arthroscopy of the knee].
The purpose of this study was to assess the analgesic effects of intra-articular injection of a morphine-bupivacaine combination following knee arthroscopy. 47 patients were evaluated. Knee arthroscopies were all performed under general anaesthesia, using propofol, alfentanil, isoflurane and nitrous oxide. Analgesic effects were evaluated by a visual analogic pain scale. ⋯ Analgesia was good in the immediate postoperative period, with minimal side effects. The serum bupivacaine levels were low. However the analgesic efficacy of intra-articular injection of morphine-bupivacaine should be corroborated through a double blind study.

[Inhalation anesthesia in unusual situations: the Eole 2 NA ventilator].
The volumetric ventilator Eole 2 NA has been adapted to work as an anaesthesia machine with low flow or closed system. This modified device is very easy to use in exceptional situations: because of its strength and reliability; its favorable quality/price ratio; versatile electrical supply: mains (220 volts) or 24 D. ⋯ V. from internal battery (2 hours autonomy) or external battery (8 hours autonomy); gas economy: less than 1 L.min-1 of fresh gas flow, whether O2/N2O = 0.5 L.min-1 of each gas or 1 L.min-1 delivered by an oxygen concentrator. Clinical trials are discussed.

Comparative Study Clinical Trial Controlled Clinical Trial[Intra-articular analgesia after arthroscopy of the knee].
In 33 patients the authors compared two protocols for postoperative analgesia after elective arthroscopy of the knee. One group (n = 11) received plain bupivacaine 0.25% by intra-articular administration. ⋯ The last group (placebo group: n = 11) received the same volume of saline. The combination of bupivacaine with fentanyl reduced postoperative pain more effectively than plain bupivacaine and the analgesic effect was still present 9 hours after the arthroscopy.

Isolated lower limb injuries are very common; difficulties for emergency anaesthesia may come from full stomach and drug interferences. The outcome of geriatric-fractured hip is influenced neither by a preoperative delay shorter than 48 hours, nor by the choice of anaesthetic technique; Nevertheless the use of acrylic cement is associated with an increased early mortality rate in hemiarthroplasties. ⋯ Spinal anaesthesia using 0.5% plain bupivacaine produces a block quickly achieved, not influenced by posture, allowing surgical installation and procedures. Postoperative analgesia using local anaesthetics may obscure symptoms of compartment syndrome which occasionally complicate tibial and femoral nailing.
