Analgesia from morphine and ketamine. A comparison of infusions of morphine and ketamine for postoperative analgesia.

Ketamine 4 micrograms/kg/minute produced pain relief similar to that from morphine 33 micrograms/minute in a double-blind study that compared analgesia from constant-rate intravenous infusions of the two drugs in 60 patients. The analgesic efficacy of the infusions, as assessed by pain scores and the requirement for supplementary self-administered morphine, was poor. Ventilatory depression, the most significant side effect, occurred only in patients who received morphine infusion. The low dose ketamine infusion did not provide clinically useful analgesia even though adequate plasma concentrations were achieved.

Clinical Trials as Topic↗

Patient-controlled analgesia. Experience of two new machines.

Two modern patient-controlled analgesia pumps have been evaluated in the laboratory and in clinical use. Both machines generally performed satisfactorily and patients achieved good pain relief from self-administered morphine. The relative merits of the two pumps are discussed and although the on demand analgesic computer is preferred, a substantial investment of time on the ward is required to provide continuous patient-controlled analgesia.

Equipment Design↗

A disposable device for infusion analgesia. An evaluation of the Travenol infusor.

The performance of the Travenol infusor when used to administer an intravenous infusion of analgesic after surgery has been investigated. Mean flow was very similar to the manufacturer's quoted figure of 2 ml/hour, but there was a large interindividual variation. Results from a laboratory study suggest that this was due to variation in the manufacture of the infusor.
