This study compared the analgesic efficacy of intermittent injections of intrathecal fentanyl (10 micrograms), meperidine (10 mg), or sufentanil (5 micrograms) administered to 65 parturients during the first stage of labor. The groups did not differ in onset or duration of effective analgesia. The meperidine group, however, had significantly lower pain scores once cervical dilation progressed beyond 6 cm. Side effects included mild pruritus and nausea. After intrathecal drug injection, variable decelerations of the fetal heart rate increased in the fentanyl and meperidine groups. All neonates had a 5-min Apgar score of 7 or more. We conclude that intermittent intrathecal injections of fentanyl, meperidine, or sufentanil can provide adequate first-stage labor analgesia. Meperidine appears to provide more reliable analgesia as the first stage of labor progresses.

This study compared naloxone and nalbuphine when administered for treatment of side effects after epidural morphine, 5 mg, given for postcesarean analgesia. Patients requesting treatment for pruritus or nausea randomly received, in a double-blind fashion, up to three intravenous doses of either naloxone 0.2 mg (group 1; n = 20) or nalbuphine 5 mg (group 2; n = 20). The incidence of vomiting, the severity of nausea and pruritus, and the degree of sedation and pain were assessed before and 30 min after each dose. The first dose of nalbuphine decreased the incidence of vomiting (P < 0.005) and the severity of nausea and pruritus (P < 0.01), whereas naloxone caused no significant changes. Sedation scores increased after nalbuphine (P < 0.05) and remained unchanged after naloxone, whereas pain scores increased after naloxone (P < 0.01) and were unchanged after nalbuphine. Eighteen patients in group 1 and 12 in group 2 received a second dose, and 8 and 4 patients, respectively, a third dose. Other than decreased pruritus after the second dose with both drugs, no further changes occurred. We conclude that nalbuphine is superior to naloxone for the treatment of side effects after epidural morphine. However, persistent symptoms may require supplemental therapy, as repeated doses proved less effective than the initial dose.

To develop a regimen that would provide good analgesia after cesarean section with minimal side effects in the setting of prolonged (> 24 h) epidural infusion, buprenorphine or fentanyl was combined with 0.03% bupivacaine in a double-blind study of 23 parturients. Patients were randomly assigned to two groups: group I (n = 12), patient-controlled analgesia by epidural infusion of buprenorphine (3 micrograms/mL) with 0.03% bupivacaine; group II (n = 11), patient-controlled analgesia by epidural infusion of fentanyl (2 micrograms/mL) with 0.03% bupivacaine. Plasma for determination of opioid concentrations was obtained at intermittent intervals. Pain relief was similar and satisfactory in both groups. The median overall satisfaction score was higher (10.0 vs 7.5; P < 0.03) for group II. Pruritus was mild in most patients. Nausea and vomiting, which were most disturbing to the patients, were seen only with buprenorphine. No patient had a respiratory rate of < 12 breaths/min. Mean plasma opioid concentrations did not exceed 1 ng/mL during the study. However, four patients (33%) in group I and six patients (55%) in group II experienced sensory loss in the lower extremities, which made ambulation difficult. One patient in each group developed extensive pressure blisters on both heels. These complications led us to terminate the study. We conclude that 0.03% bupivacaine used in combination with an opioid in prolonged epidural infusions produces a high incidence of sensory loss in the lower extremities and is unsuitable for situations in which early ambulation is desired.

Although epidural opioids frequently are used to provide postoperative analgesia, several articles have suggested that the analgesia after epidural fentanyl is similar to that after an equal dose of fentanyl given intravenously. To address this issue further, 29 postthoracotomy patients were studied in a randomized, double-blinded trial comparing a lumbar epidural fentanyl infusion with an intravenous fentanyl infusion for analgesia, plasma fentanyl pharmacokinetics, and respiratory effects for 20 h postoperatively. In all patients in both groups, good analgesia was achieved (pain score less than 3, maximum 10) over a similar time course, although the patients receiving epidural infusion required a significantly larger fentanyl infusion dose than did the patients receiving intravenous infusion (group receiving epidural fentanyl infusion: 1.95 +/- 0.45 micrograms.kg-1.h-1; group receiving intravenous fentanyl infusion: 1.56 +/- 0.36 micrograms.kg-1.h-1; P = 0.0002). The time course for the plasma fentanyl concentrations was similar in the two groups, and plasma fentanyl concentrations were not significantly different at any sampling period (T7-T20; group receiving epidural fentanyl infusion: 1.8 +/- 0.5 ng/ml; group receiving intravenous fentanyl infusion: 1.6 +/- 0.6 ng/ml; P = 0.06). Similarly, calculated clearance values for the two groups were not significantly different (group receiving epidural fentanyl infusion: 0.95 +/- 0.26 l.kg-1.h-1; group receiving intravenous fentanyl infusion: 0.87 +/- 0.25 l.kg-1.h-1; P = 0.3). Both groups demonstrated a similar degree of mild to moderate respiratory depression postoperatively, which was assessed with continuous respiratory inductance plethysmography and sequential arterial blood gas analysis. Side effects (nausea, vomiting, pruritus) were mild and did not differ between groups.(ABSTRACT TRUNCATED AT 250 WORDS)

A single dose of epidural morphine (EM) usually produces 24 h of post-cesarean section (CS) analgesia and patients require supplemental analgesics beyond this period. This study assesses if a second dose of EM administered 24 h after the first one offers superior therapeutic efficacy compared to conventional analgesics. Patients (n = 100) were randomized to receive one or two doses of epidural morphine. In all patients, EM 5 mg was administered after delivery. After 24 h patients received epidurally either normal saline (n = 50, Group 1) or morphine 5 mg (n = 50, Group 2). An independent observer used a visual analogue scale to assess nausea, itching, and analgesia 24 h after each injection. Results were expressed as mean +/- 1 s.e. mean and analyzed using nonparametric methods. The second dose of EM produced a significantly lower incidence and severity of nausea and itching than did the first dose (P < 0.01) in Group 2 with no difference in analgesia. The second day postoperative pain score in Group 1 was significantly greater than the first day score in the same group, and significantly greater than the severity score in Group 2. Only 36% of patients receiving two doses of EM required supplemental analgesics beyond 48 h compared to 76% of those receiving one dose (P < 0.01). No serious complications were noted. In summary, the use of a second dose of EM for post-CS analgesia produces better analgesia and reduces the need for oral analgesics. The second dose produced fewer side-effects, probably due to acute tolerance to morphine.

A total of 110 adults with acute ear, nose and throat infections were treated orally with 750 mg/day (n = 9) or 1500 mg/day (n = 46) sultamicillin, or 500 mg/day (n = 51) or 1000 mg/day (n = 4) cefuroxime axetil for a minimum of 5 days. Variations in dose and duration of treatment were due to severity of symptoms. After treatment with sultamicillin for 8.1 +/- 1.5 days or with cefuroxime axetil for 7.9 +/- 1.6 days, local pain, erythema, exudate, oedema and adenopathies were improved in both treatment groups and all sultamicillin-treated patients were apyretic. All sultamicillin-treated and all but three cefuroxime axetil-treated patients experienced cure or improvement; only one cefuroxime axetil-treated patient discontinued treatment due to treatment failure. Gastrointestinal adverse events occurred in both treatment groups (eight sultamicillin-treated patients and three cefuroxime axetil-treated patients); one patient receiving cefuroxime axetil discontinued treatment due to nausea. Pruritus was reported by one sultamicillin-treated patient.

Alpha 1-proteinase inhibitor (alpha 1-PI), a serine protease inhibitor, was tested for its efficacy for the treatment of recalcitrant atopic dermatitis. Atopic dermatitis affects both children and adults and has no established etiology. We hypothesized that during inflammation there is an excess of serine proteases and a deficiency of their naturally occurring inhibitors at the local site of tissue injury, even though there is a normal serum level of serine protease inhibitors. This pilot study consisted of a nonblinded trial using alpha 1-PI at a concentration of 20 mg/mL in an aqueous solution in an alternate day schedule in conjunction with a 1% cream of alpha 1-PI (Stage I) and a 5% cream of alpha 1-PI for maintenance therapy (Stage II). Before enrollment in this trial all six patients failed to respond to high potency topical steroids. Safety was gauged by careful clinical monitoring of subjective complaints, objective findings of erythema, edema, and serial measurements of blood chemistries and complete blood counts. Wound healing was documented by serial photography. Written informed consent was obtained from each patient. All six patients showed significant clinical improvement within 6 to 21 days of initiation of alternate day therapy. Alpha 1-PI stopped pain, pruritus, and promoted tissue healing without scarring in all six patients. No adverse side effects of therapy were documented by clinical history, physical examination, or by blood studies after 120 days of therapy. Atopic dermatitis may be one example where inflammation is due to an imbalance of serine proteases and their naturally occurring inhibitors.(ABSTRACT TRUNCATED AT 250 WORDS)

The association of extremely diluted concentrations of opioids and local anesthetics appears to be highly promising for pain control during labour. This study examined the efficacy of the association of Fentanyl 100 mcg and Bupivacaine 10 mg in second-stage labour pain and perineal pain. The study which was carried out in 20 patients confirmed the lack of collateral effects on the fetus, mother (except for slight itching in 25% of cases) and the progress of labour. A virtually total elimination of pain was obtained in all cases during the dilatation and expulsion stages. During the second stage of labour pain was completely abolished in 50% of cases, whereas in the remaining 50% it lasted on average for 13 minutes. Perineal analgesia was sufficient to allow episiorrhaphy in 50% of patients without resorting to the use of local anesthetic.

At the beginning, the way intrathecal morphine was used for postoperative pain relief was quite unfortunate, because the doses derived from experience with morphine-tolerant cancer patients were considerably too high and respiratory depression occurred frequently. Subsequent dose-finding studies showed that the doses of morphine used initially could be reduced by a factor of ten without loss of the analgesic effect and with a marked reduction in side-effects. No respiratory depression has been reported when doses below 0.1 mg morphine are used. METHOD. In this prospective study the effect of 0.06 to 0.08 mg intrathecal morphine, mixed with the local anaesthetic for spinal anesthesia, was investigated in surgical patients aged 21 to 81 years, ASA grade I or II, scheduled for orthopaedic operations or herniorraphies. Thirty unpremedicated patients were enrolled in the study and were, after informed consent, randomly allocated to a control group without morphine or to a morphine group. The analgesic effect was assessed by the time interval between the administration of the spinal anaesthesia and the first demand for an analgesic medication. The mood state was evaluated with the adjective checklist of Janke and Debus 6 h after the spinal anaesthesia. RESULTS AND DISCUSSION. In the control group half of the patients asked for an analgesic medication within 275 min (median) after the spinal anaesthesia, and all patients within 420 min, whereas in the morphine group half of the patients asked for an analgesic within 1170 min (median). Seven patients had not required an analgesic at the termination of the observation period 20 h after the spinal anaesthesia. The mood status showed no difference between the two groups, in particular, no dizziness or drowsiness after morphine. There was no difference in the incidence of side-effects such as nausea or urinary retention between the two groups. Pruritus was not reported spontaneously but was found upon questioning in five patients. It was in no case disturbing. CONCLUSIONS. Morphine (0.06 to 0.08 mg) mixed with the local anaesthetic for spinal anaesthesia provided for an analgesia of more than 20 h duration in half of the patients. This technique is safe, simple, reliable and virtually free of side-effects. No particular supervision due to the administration of intrathecal morphine is necessary in this dose range if systemic opiates are avoided. If the analgesia is unsatisfactory, a non-opioid analgesic is recommended.

Administration of large doses of fentanyl is a popular method to provide postoperative analgesia after thoracotomy. It is however unclear whether epidural lumbar (L) or epidural thoracic (T) administration of fentanyl confers any major advantage over intravenous (iv) infusion. Using a randomized prospective study design, we compared the potential benefits of L, T, and iv fentanyl administration after thoracotomy in 50 patients. Epidural catheters were not injected during surgery. Postoperatively a fentanyl infusion (5 micrograms/ml) was started at 1 microgram.kg-1.h-1 after a bolus of 1 microgram/kg and adjusted to maintain a score < or = 30/100 at rest using a visual analog scale (VAS) for pain. Data were prospectively collected before surgery, at fixed intervals during the 48 h of fentanyl infusions, and the day of discharge. There was no difference between the groups in overall quality of analgesia at rest and after coughing, quantity of fentanyl delivered (L = 1.15 +/- 0.38, T = 1.22 +/- 0.23, iv = 1.27 +/- 0.3 micrograms.kg-1.h-1), incidence of pruritus needing treatment (L = 2, T = 1, iv = 0 patients), need to decrease fentanyl infusion rate because of side effects (L = 2, T = 2, iv = 4 patients), importance of pulmonary infiltrates, or arterial blood gas values. One patient (L group) needed naloxone (0.04 mg iv). Intravenous patients were more frequently nauseated (P = .009) and needed boluses of fentanyl more often (L = 3 +/- 9, iv = 6 +/- 12, T = 4 +/- 8; P = .04).(ABSTRACT TRUNCATED AT 250 WORDS)
