Comparative Study[High continuous axillary-brachial plexus anesthesia. Comparison of a new method with perivascular axillary-brachial plexus anesthesia].
High axillary brachial plexus anaesthesia was performed in 25 patients. This technique employs simple, straight forward axillary access, and produces an infraclavicular brachial plexus block which is adequate for anaesthesia of the entire arm. The technique and the equipment required are described in the text and illustrated by the figures. ⋯ The only complication that occurred was an intravenous catheter placement, which was diagnosed and corrected. No other early or late complications were observed following the use of this technique in a large group of patients. This new technique is simple and easy to master.

Comparative Study Clinical Trial Controlled Clinical Trial[Peridural anesthesia with bupivacaine-CO2 and bupivacaine-HCl. A comparative study].
Carbonated bupivacaine and bupivacaine hydrochloride were used for epidural anaesthesia in patients undergoing surgery of the lower extremities. Thirty patients received 20 ml 0.5% bupivacaine hydrochloride and 32 patients 20 ml 0.42% carbonated bupivacaine. Carbonated bupivacaine had a more rapid onset of action and spread of both sensory and motor blockade than its hydrochloride salt. The differences were statistically significant.

Comparative Study[Results of various anesthesia procedures in cesarean section].
Between 1979 and 1985, 1170 anaesthetics have been used for caesarean sections. The frequency of caesarean sections ranged from 11.9% to 14%. Since 1979, the use of general anaesthesia for caesarean sections has continually decreased from 76% to 11% in favour of regional anaesthesia, and the decrease in general anaesthesia has been most obvious since 1981. ⋯ Regarding general anaesthesia, the most frequent secondary effects were said to be tachycardia, hypotension and ventricular extrasystoles. Serious complications rarely occurred; nevertheless, when they occurred, they were a threat to life under certain circumstances. Regarding regional anaesthesia, the most frequent secondary effects proved to be vomiting, hypotension and tachycardia.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study[Epidural anesthesia with carticaine in cesarean section. A comparison with bupivacaine].
The feasibility of 1.5% carticaine, an amide-type local anaesthetic agent, for epidural anaesthesia for Caesarean section was studied in 15 parturients. As a control, epidural anaesthesia in 15 parturients was done with 0.5% bupivacaine. The quality of anaesthesia before delivery was good in both groups. ⋯ The ratio of the unmetabolized drug to that of the metabolite found in maternal serum at the time of delivery was 0.75. Umbilical venous-maternal arterial serum concentration ratio in bupivacaine patients was 0.28 and in carticaine patients 0.32. The results suggest that carticaine is a feasible drug for Caesarean section.

The question whether bupivacaine 0.75% is responsible for cardiotoxic reactions during epidural anaesthesia in obstetrics, and if so, to what extent was investigated in a retrospective study. Epidural anaesthesia with bupivacaine 0.5% and 0.75% for caesarean section were compared according to their circulatory and cardiac side effects. Contrary to American publications on the negative results with bupivacaine 0.75%, in our hands the drug proved to be very useful and reliable for epidural anaesthesia for caesarean section. ⋯ Besides complete analgesia, the high degree of motor blockade should be mentioned. No negative influence on the newborn and mother could be found. As long as the technique for epidural blockade is performed correctly and the anaesthesist is experienced bupivacaine 0.75% for caesarean section can continue to be recommended.
