[The effects of pentazocine, diazepam and midazolam in patients to reduce the uncomfortable feeling during epidural block procedure].
The effects of pentazocine, diazepam and midazolam in 100 patients to reduce the uncomfortable feeling during epidural block procedure were studied. All patients (ASA I-II) were premedicated with intramuscular atropine sulfate 0.5 mg and hydroxyzine 50 mg. To relieve pain and anxiety during epidural block procedure, pentazocine (15 mg; 20 Cases or 30 mg; 20 Cases), diazepam (5 mg; 20 Cases) or midazolam (2.5 mg; 20 Cases) was given intravenously in the operating room before epidural procedure. After the epidural block, patients were anesthetized with nitrous oxide-oxygen-isoflurane or nitrous oxide-oxygen-sevoflurane. The following day, patients' self-assessments of pain during epidural block procedure were categorized as good and fair. The effects of drugs were compared between patients with im premedication only with patients with further iv administration. Patients with pentazocine 15 mg were similar to the patients given only im premedication. Pentazocine 30 mg and diazepam 5 mg tended to allay the patients' pain feeling. Midazolam 2.5 mg was effective producing anterograde amnesia and antianxiety effects. Small doses of midazolam were effective to relief patients' uncomfortable feeling.
