Increasing the injection volume by dilution improves the onset of motor blockade, but not sensory blockade of ropivacaine for brachial plexus block.

Background And Objective: Ropivacaine used for axillary plexus block provides effective motor and sensory blockade. Varying clinical dosage recommendations exist. Increasing the dosage by increasing the concentration showed no improvement in onset.

Remifentanil or propofol for sedation during carotid endarterectomy under cervical plexus block.

Background: During carotid endarterectomy under regional anaesthesia, patients often require medication to control haemodynamic instability and to provide sedation and analgesia. Propofol and remifentanil are used for this purpose. However, the benefits, side-effects, and optimal dose of these drugs in such patients are unclear.

Waste gas exposure to sevoflurane and nitrous oxide during anaesthesia using the oesophageal-tracheal Combitube small adult.

Exposure to sevoflurane (SEV) and nitrous oxide during ventilation using a Combitube (37Fr) small adult (SA) was compared with waste gas exposure using conventional endotracheal tubes. Trace concentrations of SEV and nitrous oxide were assessed using a direct reading spectrometer during 40 gynaecological laparoscopic procedures under general anaesthesia. Measurements were made at the patients' mouth and in the anaesthetists' breathing zone.

Nalbuphine by PCA-pump for analgesia following hysterectomy: bolus application versus continuous infusion with bolus application.

The analgesic properties of the partial agonist-antagonist nalbuphine in the postoperative period are well known. When used for patient-controlled analgesia (PCA) the effectiveness of this substance is comparable to that of morphine or tramadol. However, the optimal programme for administration of nalbuphine in PCA-pumps has not been investigated.

[[Course of the progression of experimentally induced arteriosclerotic vessel wall changes after treatment with magnesium orotate] ].

There are some experimental and clinical results regarding blood vessel protective properties of magnesium orotate (CAS 27067-77-2) till now. The goal of the present investigation was to verify the therapeutical efficacy of magnesium orotate vs. its singular components in cholesterol fed rabbits.
