Randomized Controlled Trial Clinical Trial
[Remifentanil-propofol anesthesia in vertebral disc operations: a comparison with desflurane-N2O inhalation anesthesia. Effect on hemodynamics and recovery].
To ascertain whether there is a difference between total intravenous anaesthesia with propofol (P) and remifentanil (R) and inhalational anaesthesia with desflurane (D) and nitrous oxide (N) with regard to haemodynamic reactions, recovery profile and postoperative analgesic demand in patients scheduled for elective microsurgical vertebral disc resection. ⋯ Patients anaesthetised with propofol and remifentanil have significantly shorter emergence times than patients anaesthetised with desflurane and nitrous oxide. The low incidence of postoperative pain after microsurgical vertebral disc resections requires no large-scale analgesic therapy, even after total intravenous anaesthesia including remifentanil.

The aim of this study was to evaluate the quality of pain management in prehospital emergency care and to get more information about the administration of analgesics in prehospital patients. ⋯ During the prehospital period of emergency care many patients suffer from severe pain. The development of patient-oriented concepts concerning pain management could contribute to improvement of pain therapy in prehospital emergency medicine.

Currently undergoing a clinical trial a new miniaturized monoplane ultrasound probe potentially enhances the practicability of perioperative transesophageal echocardiography (TEE) without loss of echocardiographic quality. ⋯ In comparison with conventional TEE, the miniaturized TEE probe provides practicability advantages without significant loss of information for cardiovascular monitoring.

We investigated the effects of ultrapurified polymerized bovine hemoglobin (HBOC-201) on skeletal muscle tissue oxygen tension when applied before establishment of a nearly complete arterial stenosis. ⋯ These data suggest that haemoglobin solutions can reach poststenotic tissues. The increased oxygen extraction after application of HBOC-201 is associated with improved skeletal muscle oxygen tension during severe arterial stenosis.
