Two groups of mothers who underwent elective cesarean section under epidural analgesia, were studied with the aim of comparing the analgesic potency and side effects of two solutions: morphine-bupivacaine and morphine-saline. Each group comprised 100 patients. The intraoperative anesthesia was established with bupivacaine plain, 5 mg/ml, in amount 85-125 mg. Immediately after the infant was delivered, the mothers received a single epidural dose of 3 mg of preservative-free morphine chloride mixed with either 5 ml of 0.25% bupivacaine (Group I) or 0.9% saline (Group II). The intraoperative observations showed "good effect" without need for supplementation of analgesia in 82 mothers in Group I, compared with 61 mothers in Group II (p less than 0.001). The postoperative observations showed that 82 mothers in Group I were satisfied with a single dose of morphine for more than 24 hours, while in Group II the corresponding number was 63 (p less than 0.01). A significant difference in the incidence of nausea and vomiting was found between the groups; 7 of the mothers experienced nausea and 4 vomited in Group I and 17 experienced nausea and 13 vomited in Group II (p less than 0.05, for both variables). Respiratory depression was seen in one mother during surgery immediately after supplementation of morphine-bupivacaine analgesia with ketamine. Other side effects, such as itching, bradycardia and Horner's triad were rare. It may be concluded that a single epidural dose of morphine in bupivacaine will augment intraoperative analgesia and prolong postoperative analgesia. Less favorable results were obtained when morphine in saline was used. Synergism between bupivacaine and morphine is suggested.

Different doses of epidural morphine were studied in order to determine their effectiveness in providing postoperative pain relief after surgery of the lower extremities and their relationship to the incidence of untoward reactions. The study was carried out in a double-blind fashion using five dosages of epidural morphine (0.5, 1.0, 2.0, 4.0, and 8.0 mg) and included 60 patients. The higher doses of morphine (2.0, 4.0, and 8.0 mg) were equally effective and more effective than the lower doses (0.5 and 1.0 mg) in providing postoperative analgesia. Nausea and vomiting were encountered more frequently with the highest dose (8.0 mg) and this finding was statistically significant (P less than 0.03). No statistically significant difference was found between the doses studied with regard to itching, urinary retention, and respiratory depression; the latter was evaluated in a subgroup of 20 patients. These data suggest that effective postoperative pain relief after surgery of the lower extremities can be achieved with relatively low doses of morphine sulfate and with minimal side effects. For the type of surgery studied, 2 mg morphine sulfate appeared to be the optimum dose.

In 12 consecutive unselected patients admitted to a consultant maternity unit one single injection of subarachnoid morphine sulphate 1.5 mg abolished pain during the first stage of labour. Pain in the second stage was abolished in four patients and lessened in three. During the early puerperium, pain at the site of the episitotomy was much reduced. Side effects included itching of the face, nausea and vomiting, and frontal headache, but these were mild and simply treated. They were even less severe in the last four patients, in whom barbotage was not used in administering the morphine. The high rate of forceps delivery and caesarean section (three cases of each) was not thought to be associated with the use of intrathecal morphine. These findings show that intrathecal morphine can abolish the pain of labour, whether spontaneous or induced, while preserving the mother's full awareness of labour and her co-operation in the second and third stages of labour. Further, controlled, trials are warranted.

Sixty-two patients were given morphine 2 mg and 69 patients were given diamorphine 0.5 mg by either the epidural or intrathecal route. All had undergone either total hip replacement or spinal disc surgery. Forty-nine out of 131 patients required no further analgesia. Diamorphine was superior to morphine and the intrathecal route more effective than the epidural. Headache, pruritus, urinary retention and nausea and vomiting were recorded, the incidence of the latter being unacceptably high, particularly when the drugs were administered by the intrathecal route: one patient required resuscitation. It is suggested that previously reported respiratory depression using these techniques is associated with the administration of other analgesics contemporaneously; that dosage should be limited to one-fifth of the estimation intramuscular dose; and that patients should be observed in a recovery ward for 24 hours.

Morphine was administered by the peridural route, in doses of 2 to 6 mg, without and with adrenalin 1/200,000, to 197 patients undergoing various surgical procedures under peridural anesthesia, with a view to lower post-operative pain. The evaluation of the effect was estimated subjectively, with the aid of a visual analogue scale and was also based on the demand for analgesia. The latency time appeared to be long: 1 hour. The overall mean duration of action is 16.25 h. The efficiency is related to the type of operation: 2-3 mg doses injected after the operation are effective in only about 50% of laparotomies and orthopedic procedures, whereas with soft tissue surgery or ano-perineal and gynecological surgery efficiency is higher (83.33% and 88.23% respectively). The injection given during the operation is more efficient, but urinary retention also seems to increase. No respiratory, circulatory or motor depression has been observed. The most untoward effects are nausea and vomiting (32.99%), urinary retention (25.40%), itching (20.30%). Combination with adrenalin does not improve the efficiency of the analgesia and secondary effects tend to be enhanced, especially urinary retention (53.57%). The spinal mediation of the effects of morphine and its access to supraspinal structures are discussed.

Approximately 175 patients at a dialysis unit were screened for entrance into the study; 43 patients were accepted according to the research criteria. These 43 subjects were given the trait anxiety test from the State-Trait Anxiety Inventory by Spielberger, Gorsuch, and Lushene (1968). Subsequently, the subjects with the ten lowest and ten highest scores were followed over two months or a total of 454 dialyses, and observed for hospitalizations, clinic appointments for treatment, and deaths. During dialysis they were observed for: hypotension; nausea and vomiting; fluid overload; infection of vascular access; clotting of vascular access; epistaxis; pain; pruritus; muscle cramps; and headache. The low anxiety group was found to have a significantly greater incidence of hypotension while the high anxiety group had a greater incidence of clinic appointments for treatment, fluid overload, and cramps. The latter group also had a significantly greater incidence of total complications with the exception of hypotension. Implications were made that appropriate nursing intervention might help prevent physical discomforts in patients on hemodialysis.

In order to investigate the analgesic effect of timing of administration of ketorolac 10 mg i.v., we recorded patient-controlled use of diamorphine at 2, 4 and 12 h after abdominal hysterectomy. In a randomized, double-blind trial, 30 patients received ketorolac before skin incision and 28 after skin closure. A control group of 32 patients did not receive ketorolac. We measured operative blood loss and assessed nausea, vomiting and pruritus. After 2 h of patient-controlled analgesia, the median cumulative diamorphine dose in the group given ketorolac before operation was less than that of the control group (95% confidence interval 8-66 micrograms kg-1; P = 0.01). There were no other statistically significant differences in diamorphine consumption between the groups. The frequency of nausea and vomiting was similar in all groups Median blood loss in the group given ketorolac before operation exceeded that of the patients who did not receive ketorolac before operation (95% confidence interval 20-149 ml; P = 0.01). We conclude that the diamorphine-sparing effect of ketorolac attributable to timing of administration was small, conferred no clinical benefit and was accompanied by increased bleeding. No patient given ketorolac complained of pruritus.

Thirty-seven eligible patients, median age 59 years (range 37-72) and median performance status 1 (0-2), with advanced, untreated, measurable gastric carcinoma were given docetaxel, 100 mg m-2 i.v. over 60 min without premedication, once every 3 weeks. Metastatic sites included the liver in 12 patients and retroperitoneal lymph nodes in 16. Eight of the 33 evaluable patients (24%) achieved a partial remission for a median of 7.5 months (3-11+). An additional 11 patients had stabilisation of disease. The patients received a median of four cycles of docetaxel (range 1-8) for a total of 156 courses. Dose reduction was necessary in 30 cycles; 14 cycles were delayed a mean of 3 days. Haematological toxicity consisted mainly of non-cumulative neutropenia, with a median nadir count of 0.35 x 10(9) l-1 (0.04-1.64) and eight episodes (5%) of leucopenic fever; non-haematological toxicities included alopecia, mild nausea and vomiting and allergic manifestations such as skin rash and pruritus. There were no drug-related deaths. Our data indicate that docetaxel is an active agent in advanced gastric cancer; further clinical investigations seem warranted.

We have studied the effect of propofol on the side effects associated with intrathecal morphine in 40 patients undergoing major arthroplasty. Patients received spinal anaesthesia with plain 0.5% bupivacaine 20 mg mixed with preservative-free morphine 0.3 mg. Before injection of the local anaesthetic, the patients were allocated randomly to receive either a bolus dose of propofol 10 mg followed by an infusion of 30 mg/24 h or equal volumes of 10% Intralipid (control group). The number of patients without postoperative nausea and vomiting (PONV) was similar in both groups. However, the incidence of nausea and vomiting was lower in the propofol (13 and 22, respectively) than in the control (34 and 36) group (P < 0.01 and P < 0.05, respectively). Severe vomiting episodes were less frequent in the propofol group (1 vs 11; P < 0.05). Four patients in the propofol group and 12 patients in the control group had itching (P < 0.05). The incidence of urinary retention was similar in both groups. There was no additional sedation attributable to propofol. In conclusion, sub-hypnotic doses of propofol protected significantly against itching and had a modest effect on PONV after intrathecal morphine.

This survey describes respiratory and mucosal symptoms of garbage-handling and recycling workers in Denmark. The study includes 20 paper-sorting workers, eight compost workers, and 44 garbage-handling workers. As a control group, 119 workers from water purification plants of Copenhagen were chosen; workers in our study had a lower mean age and shorter mean employment time than did members of the control group. There was no significant difference in tobacco consumption between the groups. Garbage-handling workers were exposed to a significantly higher mean concentration (SD) of total dust than were water supply workers-0.74 (0.77) mg/m3 compared with 0.42 (0.25) mg/m3 (p < 0.05). Total count of microorganisms was significantly higher in garbage-handling and composting areas compared with paper-sorting as well as water supply areas 0.46 (0.125) x 10(5), 0.54 (0.77) x 10(5), 4.7 (5.89) x 10(3), and 0.08 (0.04) x 10(3) cfu/m3, respectively (p < 0.05). This difference could not be explained as an effect of differential growth requirements. Significantly higher amounts of gram-negative bacteria were found in composting and garbage-handling plants than in water-supply plants. In garbage-handling plants only, there were significantly higher amounts of endotoxins than in paper-sorting plants. Significantly higher prevalence of chest tightness (14%), flu-like symptoms (14%), itching eyes (27%), itching nose (14), and sore or itching throat (21%) were found among garbage-handling workers, compared with, respectively, 1, 1, 11 and 0% among water-supply workers. Furthermore, prevalence of nausea and vomiting or diarrhea rose from 2% and 7% among the water-supply workers to 19% and 27% among the garbage workers.(ABSTRACT TRUNCATED AT 250 WORDS)
