Randomized Controlled Trial Comparative Study Clinical TrialA contribution to the monitoring of neuromuscular blockade: an evaluation of the Datex Relaxograph.
The Datex Relaxograph is a neuromuscular transmission monitor, which measures the degree of neuromuscular blockade during anesthesia. In order to evaluate the reliability of the Relaxograph, results, obtained with this apparatus, were compared with simultaneous mechanical measurements obtained with the Myograph 2000 (Biometer). Although there was a good correlation between the two throughout the study, a shift towards mechanical responses was observed in all cases. ⋯ Results show that neither drug offers major clinical advantages over the other. In a third study, a new bolus-constant infusion regimen of atracurium was evaluated. Results show that it produces a predictable and stable neuromuscular blockade.

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.

Randomized Controlled Trial Comparative Study Clinical TrialLocal versus general anaesthetic in the management of the fractured nose.
Displaced fractured noses are usually manipulated under general anesthetic. The appearances of fractured noses were assessed and the airways measured by rhinomanometry before and after nasal manipulation in 29 patients. Seventeen received a local anaesthetic (LA) and 12 a general anaesthetic (GA) for the manipulation. ⋯ Bony manipulation did not affect the nasal airway. Local anaesthesia was acceptable to all but one patient. The benefits, including those of cost and safety, of local anaesthetic for manipulation of almost all fractured noses are discussed.

[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
Postoperative recovery after general anaesthesia with and without retrobulbar block in retinal detachment surgery.
This study was to determine whether general anaesthesia plus retrobulbar block would be a better anaesthetic technique than general anaesthesia alone in retinal detachment surgery. Twenty-eight patients were allocated randomly to either general anaesthesia with retrobulbar block or general anaesthesia alone. The anaesthetist involved was blinded as to whether a retrobulbar block was performed or not. ⋯ Those who received general anaesthesia plus block recovered significantly more rapidly than those receiving general anaesthesia alone. The time to opening of eyes on command (p less than 0.05), telling the correct date of birth (p less than 0.01), reaching a full recovery score (p less than 0.005) and performing a simple motor task (p less than 0.025) was shorter in patients with general anaesthesia plus block. Thus general anaesthesia plus retrobulbar block was superior to general anaesthesia alone in terms of pain and recovery after operation.
