Randomized Controlled Trial Comparative Study Clinical TrialComparison of diazepam and midazolam as oral premedicants for bronchoscopy under local anesthesia.
A randomized double blind comparison between diazepam 10 mg, and midazolam 15 mg as oral premedicants in diagnostic fiber optic bronchoscopy under local anesthesia was made. The subjective assessments by the patient, the observer and the bronchoscopist showed that midazolam 15 mg orally gives an at least comparable degree of sedation, relief of anxiety and patient's tolerance as diazepam 10 mg orally. ⋯ Psychomotor recovery after 4 hours is better after midazolam 15 mg than after diazepam 10 mg. No adverse reactions were seen with both premedicants.

The concept of a closed peri-neurovascular space surrounding the cervicobrachial plexus, introduced by A. Winnie, allows the blockade of the cervical and brachial plexuses by means of a single puncture technique. The single puncture has positive advantages: 1. ⋯ A new indication seems to be the implantation of a cardiac pacemaker. Complications often quoted in literature are Horner syndrome-a minor complication-and blockade of the ascending branches of the recurrent laryngeal nerve and of the phrenic nerve. The risk of a pneumothorax is almost nil.
