Preoperative oral administration of fast-release morphine sulfate reduces postoperative piritramide consumption.

The aim of this prospective randomized placebo-controlled double-blind study was to investigate the effect of premedication with morphine sulfate on postoperative pain. Ninety-eight ASA I-III patients undergoing total replacement of the knee or hip joint were randomly assigned to one of two groups. Group 1 received 20 mg morphine sulfate p.

Effect of pre-emptive hydromorphone administration on postoperative pain relief--a randomized controlled trial.

Background And Aim Of Study: Pre-emptive analgesia represents a treatment strategy which tries to prevent the development of pain by inhibiting central reactions to peripheral sensory stimuli. In a prospective randomized double-blind placebo-controlled study, the effect of oral premedication with 4 mg of a slow-release hydromorphone preparation on postoperative piritramide consumption and subjective pain perception is being evaluated.

Patients And Methods: 96 women undergoing hysterectomy were randomly assigned to four study groups.

Desflurane maintains intraocular pressure at an equivalent level to isoflurane and propofol during unstressed non-ophthalmic surgery.

We have investigated the effects of desflurane compared with isoflurane and propofol on intraocular pressure (IOP) in 48 ASA I-II patients undergoing elective non-ophthalmic surgery. Anaesthesia was induced with thiopental 3-5 mg kg-1, fentanyl 2-4 micrograms kg-1 and vecuronium 0.1 mg kg-1.
