This is a review of Ibn al Quff's account of surgical pain relief in his surgical book Al Omdah, in which he mentioned the word anesthetic (Al moukhadder) and the involvement of physician (al tabbaaee) to give mixture of drugs to prevent pain in a surgical condition to relieve the patient from pain or to make surgical management possible. Hich indicated one rare occasion to such description in Arabic medical texts. Methods of administration of these drugs were inhalation, ingestion and by rectal suppositories. The drugs used in anesthetic sponges include all the drugs that are recorded in the modern literature of anesthesia. They are as follows: opium, mandrake, Hyocymus albus, belladonna, Cannabis sativus, Cannabis indica, wild lettuce. The anesthetic sponge, mentioned in many references as an inhalation method, may be of symbolic value to surgery.
1. The anticonvulsant effects of subanaesthetic doses of propofol and thiopentone against PTZ-induced seizures and mortality were examined in the rat. 2. Administration of propofol (50 mg/kg, i.p.) 5 min prior to PTZ treatment increased the 2 h CD50 and the 24 h LD50 of PTZ by 3.4-fold, whereas thiopentone pretreatment (20 mg/kg, i.p.) increased these values by more than five-fold. 3. Both propofol and thiopentone prolonged the latency to the onset of clonic seizure but the effects of the former were more marked. 4. The data demonstrate that propofol was more effective than thiopentone in providing complete protection against PTZ-induced seizures for the first 30-40 min of observation and that thiopentone, because of its sustained effects, was more effective in reducing the cumulative incidence of seizures and mortality over 2 and 24 h, respectively. 5. We conclude that propofol is a very effective anticonvulsant and provides complete protection of short duration against PTZ-induced seizures in the rat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
