[Possible patient overheating by OP-table heating equipment].
The technical equipment used in the operation theatre must be safe and foolproof. We observed a complication of near overheating a patient using the thermomaquet heating pads. The conclusion of our observation is that such heating pads must have a high-temperature cut-off device.

Comparative Study[Comparative examinations of different types of soda lime (author's transl)].
Three different types of soda lime (Dräger-Sorb 800, Sodasorb and Tricomed) were analysed both experimentally and in patients for their capability of eliminating CO2 from the anaesthetic circle system. In the experiment Sodasorb was exhausted already after 24 minutes (transmission of 0.6 vol-% CO2) while with Tricomed these data were reached only after 35 minutes and with Dräger-Sorb 800 after 40 minutes. Regarding measurements in patients the soda limes tested showed no significant difference in this field, but again Dräger-Sorb 800 was the best in eliminating CO2 (after a 2 hours application - 1.05 vol-% CO2 after the absorber, that is in the inspiratory gas flow), followed by Tricomed (1.38 vol-% CO2) nd Sodasorb (1.49 vol-% CO2). Considering its prolonged functional performance as well as its lower dust production Dräger-Sorb 800 can be regarded as the best soda lime being available especially with respect to almost equal expensiveness.

[Epidural fentanyl analgesia for the relief of postoperative pain (author's transl)].
The results are reviewed which were obtained with epidural administration of fentanyl for the relief of pain in 134 patients who had undergone abdominal surgery or had sustained multiple fractures of the ribs. Single doses of 0.1 mg of fentanyl were given epidurally via an indwelling catheter inserted between L1/L2 or L2/L3 or, in the case of 7 patients with multiple rib fractures, between Th8/Th9. The results were satisfactory to excellent. ⋯ Epidural injections caused a steeper rise in concentration than did intramuscular administration. Although none of the patients developed respiratory depression the possibility of respiratory failure should be taken into account when employing epidural fentanyl analgesia. The method is very effective in intensive therapy for relieving postoperative or post-traumatic pain, but is unsuitable for the relief of chronic pain because the analgesic effect is comparatively short-lived.

[Micropore filters for preventing venous air embolism during infusions (author's transl)].
The use of automatic pumps in intensive care medicine does not preclude the risk of accidental air embolism. The repeated introduction of small air bubbles into the infusion system in the course of additional medication may have a cumulative effect resulting in the blocking of the pulmonary capillary system. ⋯ The efficacy of the microfilter Ultipor type FAE-020 (marketed by Pall Biomedizin GmbH) in preventing the introduction of air was tested in 50 specimens with 650 single injections and 10 slow drip infusions by means of the ultrasound Doppler technique. The filters reliably stopped the introduction of air into the circulation.
