A double blind placebo-controlled study on the rectal administration of morphine as a premedication in abdominal hysterectomy
2000
Abstract Benzodiazepines are now commonly used as anxiolytic premedication prior to surgery. However, the role of opioids, as a premedication, has diminished over the last decades and they are no longer routinely used for premedication. Rather, opioids are generally used to treat severe pain in the postoperative period. Studies have shown that both NSAIDs and opioids improve analgesia in the early postoperative period. Until now, there have been no studies investigating the effect of morphine as a rectal premedication in adults in combination with blood levels of morphine. The effect of a rectal premedication with 30 mg of morphine sulphate, on postoperative pain levels and opioid consumpti…
Rectal pH in children
1989
In an attempt to establish normal values for rectal pH in children, we have measured pH in 100 paediatric patients. Measurement of rectal pH was performed in 25 infants and 75 children (27 girls and 73 boys) using a monocrystalline antimony electrode. Rectal pH was 9.6 +/- 0.9 (mean +/- SD, range 7.2 to 12.1) and was independent of sex, age and nutrition. This wide range of rectal pH values offers a possible explanation for the widely scattered bioavailability of drugs administered by the rectal route. Mean rectal pH was considerably higher than that reported for adults; this unexpected alkalinity should be taken into account, when drug formulations are considered for rectal administration …
