Randomized Controlled Trial Clinical Trial
Influence of droperidol on nausea and vomiting during patient-controlled analgesia.
We have studied the addition of droperidol to morphine during patient-controlled analgesia (PCA) in 57 patients using PCA after abdominal hysterectomy. Patients in group 1 (control group) received placebo at induction of anaesthesia and a PCA containing morphine; those in group 2 received droperidol 1.25 mg and a PCA containing morphine and those in group 3 droperidol and a PCA containing droperidol 0.05 mg mg-1 of morphine. ⋯ We did not observe side effects attributable to droperidol. We conclude that droperidol added to morphine in PCA reduces nausea and antiemetic requirements after abdominal hysterectomy.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled epidural analgesia in obstetric anaesthetic practice.
A randomised single-blind controlled study was made of 60 patients to evaluate the effectiveness of epidural patient-controlled analgesia (PCA) device for obstetric management compared with a continuous infusion system. In both cases 0.125% plain bupivacaine was used. It was found that epidural PCA is at least as effective as an infusion system in producing analgesia and has the advantages of increased satisfaction and reduction of local anaesthetic requirement. Whether there are also advantages resulting from less obstetric intervention at delivery has not been proven.

Randomized Controlled Trial Clinical TrialPreoperative infiltration of the surgical area enhances postoperative analgesia of a combined low-dose epidural bupivacaine and morphine regimen after upper abdominal surgery.
In a randomized, blinded trial we assessed the value of adding preoperative infiltration of the surgical area with bupivacaine to a low dose epidural regimen for postoperative pain treatment. Forty-nine patients scheduled for major upper abdominal surgery during combined thoracic epidural (bupivacaine + morphine) and general anaesthesia were studied. Postoperative analgesia was epidural bupivacaine 10 mg/hr-1 + morphine 0.2 mg/hr-1 for 72 h. ⋯ However, during mobilization group I had lower pain scores compared to group II (P < 0.05). There was a significant reduction in the need for supplemental intramuscular morphine in the treatment group compared to the control group (P < 0.05). Thus an enhanced analgesic effect was demonstrated by adding preoperative infiltration of the surgical area with local anaesthetic to a low dose epidural bupivacaine/morphine regimen after upper abdominal surgery.

Randomized Controlled Trial Comparative Study Clinical TrialEfficacy of low-dose epidural anaesthesia in surgery of the anal canal--a randomised controlled trial.
The aim of the study was to compare in terms of patient comfort, surgical requirements and anaesthetic safety, the difference between epidural and general anaesthesia in patients undergoing surgery of the anal canal. The study was undertaken on 50 adult patients undergoing anal surgery. ⋯ Advantages and disadvantages of both methods were noted in the study. It was concluded that low-dose epidural is a more effective means of providing analgesia, while maintaining adequate sphincter tone for surgery on the anal canal, than general anaesthesia.

Informed consent--recall of risk information following epidural analgesia in labour.
Recall of information pertaining to informed consent for epidural insertion in 40 primiparous labouring women was assessed. The recall of informed consent was compared between those patients who had attended antenatal epidural education classes, and those who had not. ⋯ Recall of information was significantly better in patients who had attended antenatal epidural education classes. We recommend that informed consent for epidural analgesia in labour be obtained antenatally whenever possible, and that details of the consent be recorded in the patient's notes.
