To evaluate relative efficacy, safety, and time course of analgesia, nefopam (45 and 90 mg), a new centrally acting nonnarcotic analgesic, was compared with propoxyphene (65 mg) and placebo in a single oral dose, parallel, stratified, randomized, double-blind trial with 100 hospitalized postpartum women with medium or severe episiotomy pain. Using subjective reports as indices of response, patients rated pain intensity and side effects at periodic interviews for 6 hr. After 45 and 90 mg nefopam, 21 of 25 and 20 of 25 patients (p less than 0.01) reported more than 50% reduction of pain, whereas after 65 mg propoxyphene 18 of 25 (p less than 0.05) and after placebo 11 of 25 reported reduction in pain. Relative efficacy, based on summed pain intensity differences, showed measurable but modest dose-dependent analgesia with nefopam, suggesting that the effectiveness of 65 mg propoxyphene lay between 45 mg nefopam and placebo. Side effects included mild dizziness and hypothermia after nefopam and mild elevation of diastolic arterial pressure after nefopam and propoxyphene. Our results suggest that 45- and 90-mg doses of nefopam induced more analgesia than 65 mg propoxyphene in the relief of episiotomy pain.

We report the extradural administration of low-dose morphine in 10 ml of 10% dextrose (2-3 mg) to 98 adult patients with various types of acute and chronic pain. Extradural morphine injections were given either via a Tuohy needle (single or repeat injection) or via an extradural catheter. Pain relief was evaluated by subjective scoring and by the subsequent need for systemic analgesics. In 56% of patients, pain relief was considered good or excellent, in 24% it was fair, and in 20%, poor. The best results were after surgery and trauma and in patients with advanced peripheral vascular disease. The analgesia of each dose of extradural morphine lasted for 8 h (mean range 4-36 h). There was no motor, sensory or sympathetic blockade and no respiratory or haemodynamic complications. Dizziness and vomiting occurred in two patients, and urinary retention for about 12 h in three.

Supine and erect arterial pressures were measured daily for six to seven days after delivery in 100 patients, of whom 50 had received epidural analgesia. There was no difference in the magnitude of postural hypotension between the epidural and control groups on any day after delivery, although in both groups the hypotension was greater during the first two days due almost entirely to changes in systolic arterial pressure. The incidence of dizziness on standing was similar in both groups (9%). Thus postural hypotension is no more common in women who have received epidural analgesia than in others. All patients should be helped out of bed after delivery, and any patient who experiences dizziness should have her blood pressure measured until the dizziness disappears.

Propiram is an orally administered opioid analgesic with partial morphine-like agonist and weak antagonist properties. Analgesic efficacy of propiram, usually 50 or 100mg, appears comparable to that of standard dosages of other oral opioid drugs [i.e. pentazocine, pethidine (meperidine)] in patients with acute pain of moderate to severe intensity arising from various gynaecological and surgical procedures, and may be superior to codeine in gynaecological and postoperative dental pain. Some evidence of a more rapid onset of action for propiram than for these opioid agents, and a longer duration of action for propiram than for codeine, is encouraging but remains to be substantiated in more extensive clinical use. The tolerability profile of propiram resembles those of others in its class, with drowsiness, nausea and vomiting, and dizziness experienced most frequently in controlled trials. The apparently low propensity of propiram for development of physical dependence and psychotomimetic effects requires confirmation with wider clinical experience. Available data thus indicate that propiram is an effective, orally administered opioid analgesic suitable for providing relief of acute moderate to severe pain arising from various surgical or gynaecological procedures, and that the drug is likely to become a useful alternative in such conditions where opioid analgesia is appropriate.

A prospective, open-label study of the effectiveness of transnasal butorphanol in the treatment of pain resulting from musculoskeletal injuries. Twenty-eight patients with strains (n = 20), fractures (n = 6), contusions (n = 1), and stab wounds (n = 1) were included. All patients were examined by an attending level emergency medicine physician and deemed to have pain severe enough to warrant parenteral narcotic analgesia. All patients received an initial 1-mg dose of transnasal butorphanol. Subsequent dosing was flexible depending on response to the initial dose. All patients received pain relief from transnasal butorphanol, and only one requested alternative analgesic medication. Fifty-seven percent (n = 16) of patients noticed at least a little relief of pain within 5 minutes of administration and 93% (n = 26) received at least a little relief within 15 minutes. Seventy-one percent of the patients received a 50% reduction of pain within 60 minutes. No serious side effects were noted, but drowsiness occurred in 82% (n = 23) and dizziness in 54% (n = 15) of the patients. One patient discontinued participation in the study because of nausea. In this limited trial transnasal butorphanol proved to be a rapidly effective opioid analgesic. Further controlled studies comparing transnasal butorphanol with standard parenteral narcotics are needed.

A prospective single-blind study was conducted to compare flunitrazepam vs trazodone in the premedication of patients undergoing day-case surgery for termination of pregnancy, with particular regard to the degree of preoperative sedation, intraoperative analgesia and postoperative recovery. 86 patients were randomly allocated to receive orally 45 minutes before the surgical procedure either flunitrazepam 2 mg (group F) or trazodone 50 mg (group T). In both groups anaesthesia was achieved by i.v. fentanyl 2.5 micrograms/kg and ketamina 250 micrograms/kg. Patients in group F showed a deeper degree of preoperative sedation. There were no significant differences in intraoperative analgesia and in the immediate arousal time. In the postoperative period, the incidences of emetic symptoms and dizziness were similar in both groups; the incidence of drowsiness was significantly higher in group F at 120 minutes but not at 180 minutes of observation. Psychomotor performance was assessed preoperatively two days before the surgical procedure and 60, 120 and 180 minutes after surgery, using the Toulouse-Pieron test and the reaction time to a luminous stimulus with the aid of a computerized analogic tachystoscope (Neurometer). Trazodone allowed a more rapid recovery of psychomotor performance and it can represent a valid alternative to the use of benzodiazepines in the premedication of day-case surgical patients.

We compared, in a double-blind randomised study, intramuscular ketorolac 30 mg (n = 49) and intramuscular pethidine 75 mg (n = 51) for analgesia after elective caesarean section under general anaesthesia. Anaesthesia was induced with thiopentone and suxamethonium and maintained with atracurium, nitrous oxide and isoflurane. Intravenous fentanyl 100 micrograms was given after delivery of the neonate. In the recovery ward, patients who requested analgesia were allocated randomly to receive ketorolac 30 mg or pethidine 75 mg intramuscularly. Analgesia was assessed at intervals up to six hours, using a visual analogue scale and a four-point verbal scale, while duration of analgesia was taken as the time until the patient requested additional analgesia. There was no difference in the duration of analgesia between groups (Mann-Whitney test P = 0.27, Mantel-Haentszel test P = 0.17). Twenty-six patients in the ketorolac group and 17 patients in the pethidine group requested further analgesia by 90 minutes. However, four patients in the ketorolac group and six patients in the pethidine group requested no further analgesia within 24 hours. Pain VAS and overall assessment of analgesia was similar between groups, although more side-effects (nausea, dizziness) were noted in the pethidine group. Ketorolac 30 mg and pethidine 75 mg provided similar but variable quality of analgesia after caesarean section.

Treatment of postoperative pain is often insufficient. It normally consists of systemic application of an analgesic drug or a regional technique of analgesia. Fentanyl-TTS may be a new approach for postoperative pain therapy. Fentanyl is incorporated into a transdermal system; after application to the skin continuous release of therapeutic doses is achieved for a period of 72 h. Serum peak levels are obtained 8-16 h after application; the serum half-life is about 16-21 h because of the dermal depot. Fentanyl-TTS was administered in several clinical studies for therapy of postoperative pain. The efficacy of this new form of application could be demonstrated. For the first 12 h the patients needed supplementary doses of analgesic drugs in the same range as the placebo groups because of the lag time of fentanyl-TTS. In the following 12 h the need for supplementary analgesics was significantly reduced. After removal of the patch, the need for analgesics was still reduced for 12 h. In 21 of 341 patients respiratory depression occurred under therapy with fentanyl-TTS; no respiratory depression was observed in the placebo groups. Thus, respiratory depression might occur in up to 9% of postoperative patients treated with fentanyl-TTS. Other adverse effects were nausea (62%), vomiting (26%), sedation (22%), urinary retention (11%), headache (5%), and dizziness (8%). Local reactions under the patch were erythema (39%) or pruritus (9%). These phenomena disappeared within a few hours. The pharmacokinetics of fentanyl-TTS have two major drawbacks: during the first 12-15 h the patients need supplementary analgesics, usually opioids.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-one patients scheduled for elective cholecystectomy performed through a mini-laparotomy, were randomized to received either combined thoracic epidural anaesthesia/light general anaesthesia and postoperative balanced analgesia with continuous epidural bupivacaine 10 mg.h-1 and morphine 0.2 mg.h-1 for 38 h after surgery plus systemic ibuprofen 600 mg x 8 h-1 (N = 15) or general anaesthesia and postoperative analgesia with systemic morphine and ibuprofen 600 mg x 8 h-1 (N = 16). During postoperative epidural infusion sensory blockade to pinprick was Th4 to L1, and analgesia at rest and during mobilisation was superior compared to systemic morphine and NSAID. There were no significant differences between groups in haemodynamic responses (BP and heart rate) during rest, orthostatic stress and after walking assessed before, 24 and 48 h after operation except for a clinically unimportant lower heart rate (approximately 10 bpm) 48 h after surgery at rest and during orthostatic stress in the epidural group. There was no significant difference between groups in number of patients with a reduction > 20 mmHg (2.7 kPa) in systolic blood pressure during orthostatic stress (two in each group at 24 h) or in number of episodes of dizziness, nausea or vomiting during rest or mobilisation. These results do not support the common belief that low-dose thoracic epidural bupivacaine/morphine may prevent ambulation due to sympathetic blockade or to impaired cardiovascular adaptation to the upright position.

The authors present their experience with transnasal butorphanol to provide analgesia following orthopaedic and plastic surgical procedures in children. Transnasal butorphanol was administered to eight patients ranging in age from eight to 17 years and in weight from 34 to 64 kg. Following the surgical procedure, the patient and a parent were instructed on how to use the medication. They were instructed to administer one spray into one nostril every three h as needed for pain. The quality of analgesia was assessed twice a day using a visual analogue score of 0 to 10 (0 = no pain, 10 = worst pain imaginable). Intranasal butorphanol provided adequate analgesia in all eight patients with visual analogue scores of zero to two. Adverse effects from the medication included one report of nausea, one complaint of transient dizziness, and two reports of a bitter taste and some mild throat irritation. None of these was severe enough to preclude its subsequent use. Our preliminary experience suggests that transnasal butorphanol may offer an alternative route of delivery when intravenous administration is not feasible. Future studies are needed to compare its efficacy to intravenous and non-parenteral routes of administration. It may prove to be useful in other situations when intravenous access is lacking such as prior to invasive procedures in the outpatient clinic or emergency room.
