Relief of pain after surgery remains poor for the majority of patients. The pain is unpleasant, and is associated with arterial hypoxaemia, venous thrombosis, myocardial ischaemia and a more florid hormonal response to surgery. Regional analgesia, systemic, subarachnoid or extradural opioids and antiprostaglandin drugs are all used to treat pain after surgery. ⋯ Intravenous administration avoids both problems and excellent results have been obtained using Patient Controlled Analgesia devices, but these machines are expensive. A simple regimen suitable for application to large numbers of surgical patients is required. Continuous infusion of fentanyl 100 micrograms h-1 IV begun two hours before surgery and supplemented by a single bolus dose of fentanyl 100 micrograms IV provided an effective background of analgesia.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of bupivacaine and morphine on pain and bowel function after colonic surgery.
Sixty patients scheduled for colonic surgery were randomly allocated to four groups according to postoperative pain medication: I. Control group, the patients received oxycodone intramuscularly (0.15 mg kg-1) on request. II. ⋯ Pain intensity (visual analogue scale) was lower in Groups II and III at 3 h and in Group IV at 24 h compared to the control Group I. All the epidurally treated groups needed less additional analgesics than the control Group I. Postoperatively bowel movements occurred on the second day in Group II (bupivacaine) as compared to the fourth day in all other groups (P less than 0.05).

Randomized Controlled Trial Comparative Study Clinical Trial
Continuous intercostal blockade after cardiac surgery.
The provision of analgesia using continuous bilateral intercostal blockade was compared with that provided by conventional i.v. narcotics for the first 48 h after cardiac surgery. The subjective quality of analgesia was significantly superior with the regional technique. However, pulmonary function tests, gas exchange, lung volume, and radiological and clinical evidence of pulmonary complications were not improved. The failure to reduce morbidity and the potential for complications such as pneumothorax, makes it difficult to recommend the regional analgesia technique in this situation.

Sleep physiology, pain and mood symptoms of 8 patients with idiopathic osteoarthritis of the hands who complained of morning symptoms were compared to 7 age and sex matched subjects with similar joint pathology, but who did not complain of morning symptoms. The "AM Symptoms" group had sleep related (nocturnal) myoclonus, associated with increased morning peripheral joint tenderness and decreased grip strength, whereas the "No Complaint" group had improved mood in the morning.

Randomized Controlled Trial Clinical TrialEffect of pretreatment with acetaminophen-propoxyphene for oral surgery pain.
To determine the effect of pretreatment and multiple doses on postsurgical pain, a study of the relative analgesic efficacy of placebo, acetaminophen 650 mg, and propoxyphene napsylate 100 mg alone and in combination was conducted. Forty-five patients undergoing surgical removal of impacted third molar teeth under local anesthesia were randomly allocated to the four treatment regimens under double-blind conditions. The first oral dose was administered one hour preoperatively and the second dose when the pain became moderate or severe, following the dissipation of the local anesthesia. ⋯ Duration of analgesia was also significantly longer with both propoxyphene-containing treatments. No side effects were reported. The results suggest that pretreatment with a narcotic agonist markedly improves postoperative analgesia.
