Stability of premixed syringes of diamorphine and hyperbaric bupivacaine.

Background: It is common clinical practice to add diamorphine to heavy bupivacaine when performing spinal anaesthesia for either obstetric or general surgical procedures. If pre-filled syringes were available potential problems arising due to the wrong mixture being administered could be reduced, whilst also providing greater assurances of sterility and accuracy of dosage. It is therefore necessary to establish whether diamorphine 100 microg/mL is stable in solution with 0.

Long strictureplasty is as safe and effective as short strictureplasty in small-bowel Crohn's disease.

Background: For the past 20 years it has been shown that intestinal strictureplasty is safe and effective in the management of short strictureplasty. Long strictureplasty (> 20 cm) may be an alternative to resection in some patients, especially in diffuse disease or after previous extensive resections. We reviewed the outcome of long strictureplasty for Crohn's Disease, to examine safety and recurrence rates, compared with conventional short strictureplasty.

A comparison of patient-controlled analgesia administered by the intravenous or intranasal route during the early postoperative period.

Intranasal administration of lipophilic opioids has been shown to be an effective method of administration which is devoid of major side-effects. Whether it is as effective as intravenous administration for patient-controlled analgesia (PCA) has been investigated for fentanyl and pethidine, but not for diamorphine. This study reports a randomised controlled trial designed to compare the effectiveness of diamorphine administered as PCA utilising either the intranasal or intravenous routes.
