[Survey on practice of regional anaesthesia in Germany, Austria, and Switzerland. Part 1: Quality assurance and training concepts]. / Umfrage zur aktuellen Situation der Regionalanästhesie im deutschsprachigen Raum. Teil 1: Qualitätssicherung und Ausbildungskonzepte.

The practice of regional anaesthesia in German speaking countries was investigated by a survey. The first part of the trilogy contains the presentation and evaluation of the data about quality assurance and training concepts. In 2002 questionnaires were mailed to 750 randomly selected departments of anaesthesia and 384 hospitals participated (51.2%). The overall proportion of regional anaesthesia was 23% and in Switzerland it was significantly higher (adults: 48%; children: 31%). Of the hospitals 19% had no person who was responsible for quality assurance. The number of puncture attempts was unlimited in 59% of the hospitals. The first training steps were observed closely (complete observation: 81%). The exact beginning (48%) and end (15%/13%) of the training were often not fixed, 80% of all anaesthesia departments requested an improvement in the training for peripheral and 53% for neuroaxial regional anaesthesia techniques. Regional anaesthesia plays a highly important role. Concepts of training and quality assurance that are backed up by evidence-based medicine should be worked out to improve the training and further education in regional anaesthesia.

[Survey on practice of regional anaesthesia in Germany, Austria, and Switzerland. Part 3: Methods in obstetric anaesthesia]. / Umfrage zur aktuellen Situation der Regionalanästhesie im deutschsprachigen Raum. Teil 3: Verfahren der geburtshilflichen Anästhesie.

The practice of regional anaesthesia in German speaking countries was investigated by a survey. The last part of the trilogy contains the presentation and evaluation of the data about the methods in obstetric anaesthesia. In 2002 questionnaires were mailed to 750 randomly selected departments of anaesthesia, 384 hospitals (51.2%) responded of which 278 had an obstetric unit. Caesarean section rate was 22.5+/-8.2% and for elective caesarean section spinal anaesthesia was mostly used. General anaesthesia was never used in 58.3% of Swiss, 10.2% of German, and 21.1% of Austrian hospitals. For non-elective caesarean section 42.1% of the hospitals often used a spinal anaesthesia, and 44.8% sometimes, in Switzerland these were 92.9% and 7.1%, respectively. Pain relief for labour was usually achieved with epidural anaesthesia or drugs. The trend from general to regional anaesthesia for caesarean section is continued, as is the trend from local infiltrative techniques to epidural anaesthesia for vaginal delivery. Switzerland was in the forefront for these developments.

[Survey on current practice of regional anaesthesia in Germany, Austria, and Switzerland. Part 2: Use, success rates and techniques]. / Umfrage zur aktuellen Situation der Regionalanästhesie im deutschsprachigen Raum. Teil 2: Anwendung, Erfolgsraten und Techniken.

The current practice of regional anaesthesia in German-speaking countries was investigated in a survey. The second part of the trilogy presents data about its use, success rates, and techniques. In 2002 questionnaires were mailed to 750 randomly selected departments of anaesthesia of which 384 hospitals participated. Peripheral regional anaesthesia is used above all in traumatology and orthopaedics, 45% of the hospitals with paediatric surgery never used neuroaxial blocks. The residents achieved mean success rates of 69.7+/-11.8% for supraclavicular plexus block to 85.5+/-9.0% for spinal anaesthesia, the specialists in anaesthesia 79.2+/-11.3% (supraclavicular plexus block) to 91.0+/-6.8% (spinal anaesthesia). Standards for basic techniques, recording of success rates, and for quality assurance of peripheral nerve blocks should be worked out to improve the application of peripheral regional anaesthesia procedures. In neuroaxial anaesthesia satisfying success rates were reached in German-speaking countries. In paediatric anaesthesia its use still has many opponents.

Real-time ultrasonic observation of combined spinal-epidural anaesthesia.

BACKGROUND AND OBJECTIVE: The quality of combined spinal-epidural anaesthesia mainly depends on accurate identification of the epidural space. The real-time ultrasound control of the procedure for puncture was therefore evaluated. METHODS: Thirty parturients scheduled for Caesarean section were randomized to three equal groups. Ten control patients received conventional combined spinal-epidural anaesthesia. Ten of the remaining patients received ultrasonic scans by an offline scan technique, and 10 received online imaging of the lumbar region during epidural puncture. The epidural space was identified and needle advancement was surveyed through the interspinal and flaval ligaments. The number of attempts to advance the needle to achieve a successful puncture was measured and compared, as well as the number of vertebral interspaces punctured before successful entry into the epidural space. RESULTS: There was no difference between patient characteristics in the three groups. The visualization of the epidural structures and of the needle manipulations was very effective. In the ultrasound group, the reduction in the number of attempts at puncture was significant (P < 0.036). The number of interspaces necessary for puncture was reduced (P < 0.036) in the ultrasound online group compared with controls. The number of spinal needle manipulations was significantly reduced (P < 0.036). CONCLUSIONS: Real-time ultrasonic scanning of the lumbar spine is an easy procedure. It provides an accurate reading of the location of the needle tip and facilitates the performance of combined spinal-epidural anaesthesia.
