[Para-spinal analgesia in obstetrics].

The use of regional analgesia and anesthesia in obstetrics has been established since the end of the 19th century. According to an agreement between German societies of anesthesiologists and obstetricians, regional anesthesia may be performed by both anesthesiologists and obstetricians under certain preconditions. At the RWTH Aachen hospital, the responsibility for different anesthetic techniques is divided between anesthesiologists and obstetricians in order to reduce legal risks.

[Cerebrovascular abnormalities in pregnancy].

A 37-year-old pregnant woman without neurological history was admitted in the 21st week of pregnancy for multiple seizures. Angiography confirmed the diagnosis of cerebral angioma. The patient decided to continue with her pregnancy; caesarean section under regional anesthesia via an epidural catheter was uneventful.

[Arousal in various analgosedation schedules].

The patterns of recovery of patients who received seven different analgesic and sedative treatments were investigated with regard to the time at which the subjects awoke. For observations of the neurologic status, we developed a special score. The analgesic and sedative therapies were given at three various doses.

[Analgosedation of the ventilated intensive care patient].

Seven different schemes for analgesic anaesthesia were investigated for their clinical applicability, potential side effects, and impacts on circulation parameters of the systemic and pulmonary (peripheral) circulation as well as on the intracranial pressure. In all, so patients per group were treated. The results revealed different reactions of patients, such as a higher incidence of disturbances of the autonomic nervous system and excitation after medication withdrawal.

[Comparative studies of the postoperative phase following opioid analgesia using fentanyl and alfentanil within the scope of extracorporeal shockwave lithotripsy].

30 patients (ASA Class I-III) received opioid analgesia with fentanyl and alfentanil for extracorporeal shock wave lithotripsy. Average doses were 0.41 mg for fentanyl and 4.
