To test whether a neural network-based method could differentiate between tracheal and esophageal intubation in anesthetized patients by recognizing breathing circuit pressure and flow waveform patterns. ⋯ A neural network differentiated consistently tracheal from esophageal intubation when the ventilation test mode was used. The ventilation mode employed is feasible in most adult patients undergoing elective procedures under general anesthesia. Further research is required to train neural networks to recognize esophageal intubation in different age groups and when different ventilation modes are applied.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative complaints after spinal and thiopentone-isoflurane anaesthesia in patients undergoing orthopaedic surgery. Spinal versus general anaesthesia.
The present prospective study investigates the impact of a standardized technique of spinal and general anaesthesia on the incidence and consequences of postanaesthetic complaints dependent on age and sex of patients. ⋯ Spinal anaesthesia was associated with a lower incidence of postoperative complaints and treatments and a shorter surveillance compared to general anaesthesia. Specific complications related to spinal anaesthesia did not depend on age or sex and may allow for recommendation of this technique even in younger and female patients undergoing orthopaedic surgery.

[Study on combined acupunctural and general anesthesia in pneumonectomy].
Combined acupunctural and general anesthesia in pneumonectomy were studied. The result showed that general anesthesia complemented with electro-acupuncture at He Gu (LI 4) and San Yang Luo(SJ 8) reduced amount of Fentanyl 38-85 micrograms/h compared with general anesthesia alone. ⋯ It was considered that acupuncture in combination with general anesthesia could reduce dosage of anesthetics and the inhibition of physiological function. It is a practical and acceptable anesthetic method by the surgeon and patient.

Mivacurium is a short-acting nondepolarising muscle relaxant of the benzylisoquinoline type undergoing rapid breakdown by plasma cholinesterase. With 2.5 fold ED95, tracheal intubation can be accomplished within 2-3 min following injection. The ensuing DUR 25% (i.e. time from injection to 25% recovery of control twitch tension) is three times as long as with succinylcholine and about half as long as with equipotent doses of atracurium and vecuronium. ⋯ One of them, cis-atracurium, is five times as potent as the chiral mixture while having a similar pharmacodynamic and kinetic profile. It does not cause significant histamine release or clinically relevant cardiovascular effects at doses up to 8 times the ED95. Laudanosine release seems to be less with cis-atracurium than with atracurium.
