A comparison of the effect on gastric emptying of either enflurane or propofol given during maintenance of anaesthesia for minor surgery.
MetadataShow full item record
Twenty patients scheduled for minor gynaecological surgery were studied. Anaesthesia was induced with propofol and maintained either with enflurane/oxygen/nitrous oxide or propofol/oxygen/nitrous oxide. The rate of gastric emptying was measured indirectly by the paracetamol absorption model. The results showed that there was no significant difference in gastric emptying rate between the two groups. Recovery in the propofol group was more rapid in that paracetamol ingestion occurred earlier in the recovery period compared with the enflurane group.
