Randomized Controlled Trial Comparative Study Clinical Trial
[Frequency and severity of throat complaints following general anesthesia with the insertion of various endotracheal tubes].
Laryngeal and pharyngeal complaints following general anaesthesia are well-known problems. The frequency, extent, and intensity reported in several studies are at variance. Such transient postoperative problems should not be considered equivalent to traumatic airway injuries caused by endotracheal intubation. ⋯ The patients of groups A-D underwent oral intubation using lidocaine gel 2%; adequate cuff inflation was determined just after intubation. The patients were questioned every 24 h for 2 days postoperatively using an analogue scale and "open" and "closed" questions. The single groups were comparable in age, sex, height, weight, number of smokers, duration of operation (only groups A-D), and preoperative diseases of the upper airways.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
Epidural vs general anaesthesia and leg blood flow in patients with occlusive atherosclerotic disease.
Total leg blood flow (plethysmography), skin blood flow (laser-Doppler flowmetry), and haemodynamic stability (MAP, HR, RPP) were studied in vascular (ABI less than 1.0; n = 31) and in non-vascular (ABI greater than 1.0; n = 24) surgical patients during epidural or fentanyl-supplemented general anaesthesia. During epidural anaesthesia significant increases in total leg blood flow were observed in vascular (from 1.9 +/- 0.2 to about 3 ml/100 ml tissue/min) as well as in non-vascular (from 2.5 +/- 0.6 to about 7 ml/100 ml tissue/min) patients and leg blood flow remained high in the postanaesthetic period. During general anaesthesia total leg blood did not increase, either in vascular or in non-vascular patients, and in the postanaesthetic period blood flow values even lower than the initial ones were observed. ⋯ In vascular patients no critical redistribution of blood flow within the limb was observed irrespective of the type of anaesthesia. Good haemodynamic stability could only be maintained in the epidural group. It is concluded that epidural anaesthesia seems to offer considerable advantages over general anaesthesia for high-risk vascular patients during arterial reconstructions since better haemodynamic stability and higher leg blood flow can be achieved.
