Seventy-nine patients of end stage renal disease (ESRD) on maintenance haemodialysis were studied. Most of the cases were in their prime of life. The disease was equally common in both sexes and all ethnic groups. Chronic glomerulonephritis was the commonest cause followed by diabetes mellitus. Hypertension was the commonest associated illness. All patients were screened for hepatitis B surface antigen and antibody and those found negative were vaccinated. A-V fistula in the upper extremity was used as the vascular access in 93% cases. In 68% cases dialyzer was reused without any ill effect. Amongst the complications observed, hypotension was seen in 65%, psychological disorders in 52%, followed by nausea, vomiting, itching and cramps. Technical complications were related to A-V fistula in 45% cases. Forty three percent patients were maintained without blood transfusion and 88% showed improvement in their quality of life.

A randomised, single-blinded study was conducted to compare patient-controlled epidural analgesia with continuous infusion epidural analgesia for the treatment of pain following post-traumatic pelvic reconstruction. The patient-controlled group (n = 11) received a background infusion of 4 ml.h-1 of bupivacaine 0.125% with fentanyl 1 microgram.ml-1, and 3-6 ml bolus doses, self administered, as required (with a 15 min lockout interval). The continuous infusion group (n = 12) received a continuous infusion of the same solution through an identical apparatus, but with the demand button deactivated. This was started at 10 ml.h-1 and adjusted by the anaesthetist, as required, up to a maximum of 25 ml.h-1. Pain scores, side effects, and the volumes of drug infused were recorded over the first 3 postoperative days. One patient from each group was withdrawn because of catheter-related problems. Pain scores were similar and the incidence of nausea and pruritus was low in both groups. There was no recorded instance of respiratory depression or hypotension and there was no significant difference between the groups in the volumes of drug solution received. Patient satisfaction was equally very good in both groups. Patient-controlled epidural analgesia is an effective means of providing pain relief after post-traumatic pelvic reconstruction, but did not significantly reduce analgesic requirements in comparison with continuous infusion epidural analgesia.

Epidural anaesthesia with local anaesthetics has become a standard method of pain relief during labour. In recent years, spinal opiates, alone and in combination with local anaesthetics, have also been tried with varying degrees of success. Buprenorphine, a potent lipophilic opiate with long duration of action, has been used in several trials for caesarean section [3, 4, 6], but not yet in spontaneous labour. The aim of the present investigation was to evaluate epidural anaesthesia with bupivacaine alone and with bupivacaine+buprenorphine in comparison with no anaesthetic treatment in control parturients. METHODS. A total of 80 healthy women during labour at full term (age 18-38 years, weight 54-107 kg) were studied to evaluate the influence of 0.3 mg buprenorphine (group BB) vs placebo (group B) added to an initial dose of 15 ml plain bupivacaine 0.33% for lumbar catheter epidural anaesthesia. Plain bupivacaine 0.25% (10 ml) without any opiate admixture was used for reinjections. The control group was made up of 48 untreated parturients. After every injection, blood pressure, heart rate and respiratory rate were measured repeatedly, as were time intervals between injections, extent of blockade, duration of labour, actual and retrospective visual analogue pain score, and side effects such as pruritus, shivering or nausea and emesis. Maternal capillary blood gases were analysed three times during labour, and Apgar scores and venous and arterial umbilical blood gas analyses were obtained immediately after delivery. RESULTS. Admixture of buprenorphine 0.3 mg significantly increased the time interval between the first and second epidural doses (B: 162 +/- 47 vs BB: 224 +/- 64 min; mean, SD; Table 2) and significantly reduced the incidence of shivering (Table 9). The incidence of instrumental delivery was comparable in all groups (bupivacaine 32.5%, bupivacaine+buprenorphine 27.5%, control 21%; n.s.). No clinically relevant differences were observed between the epidural patients in onset and duration of the block (Fig. 1), analgesic efficacy (Fig. 2), duration of spontaneous labour (BB: 8.6 +/- 3.1 h, B: 8.5 +/- 2.9 h; n.s.) and vital functions of mothers and newborns. Although some statistically significant differences between the three groups were found in some parameters of the blood gas analyses (Table 7), the clinical condition of the newborns was always acceptable; Apgar scores were not significantly different. DISCUSSION AND CONCLUSIONS. The addition of buprenorphine to bupivacaine resulted in some advantages to the mother (reduced incidence of shivering) and the anaesthetist (time lapse before first reinjection was necessary) without jeopardizing the situation of the baby. Compared with untreated control parturients, retrospective pain scores during epidural anaesthesia with bupivacaine (with or without buprenorphine) were significantly lower. No clinically relevant disadvantages of epidural anaesthesia were observed. More studies are required to evaluate whether buprenorphine admixture allows a dose reduction of bupivacaine and could then claim clearer advantages than were found in the present investigation.

To assess prospectively any difference in either analgesia or side effect frequency with morphine versus meperidine, 50 patients, ages 8-16 years, were randomly assigned to receive postoperative patient-controlled analgesia (PCA) with either morphine or meperidine. A numerical rating scale pain score was obtained from each patient twice a day, and any nausea, vomiting, pruritus, or urinary retention requiring catheterization was noted. No significant difference in the incidence of side effects was noted between the morphine and meperidine groups; however, pain scores during morphine PCA were significantly less than those during meperidine PCA (P less than 0.001). These results suggest that morphine is the better opioid for pediatric PCA.

A 39-year-old woman was evaluated for possible liver transplantation due to rapidly developing hepatic failure 4 weeks after initiation of oral minocycline 100 mg twice a day for the treatment of acne. The patient developed a maculopapular rash, malaise, fever, nausea, and vomiting 2 weeks prior to admission to the hospital. On admission, her symptoms rapidly progressed to liver failure characterized by rapidly rising liver enzyme levels, worsening encephalopathy, and coagulopathy. Viral hepatitis serologies and blood cultures were all negative. After intensive supportive care for 2 weeks, the patient's condition gradually improved and she was discharged with mildly elevated liver enzyme levels and pruritus, without need of liver transplantation. Minocycline-induced hepatic injury is an idiosyncratic reaction with a sensitization period that appears to be 3-4 weeks in duration. The characteristic features include rash, fever, lymphadenopathy, and eosinophilia, as well as severe alterations in liver function. The high liver enzyme levels and the significant prolongation of the prothrombin time suggest massive hepatocellular damage. In light of the profound liver damage that occurs with this adverse reaction, care should be taken in administering minocycline to patients who have concomitant liver disease. It is recommended that patients should be instructed as to the possible signs and symptoms of toxicity and be monitored for evidence of idiosyncratic reaction or liver failure.

Gadobenate dimeglumine (formerly known as Gd-BOPTA) is a recently developed paramagnetic contrast agent that undergoes biliary as well as renal excretion. It may, therefore, be useful in MR imaging of the liver. Its safety, tolerance, and usefulness in visualizing hepatobiliary structures were studied in eight healthy subjects. Axial abdominal images were obtained with T1-weighted spin-echo and gradient-echo sequences at 1.5 T before and after IV administration of gadobenate dimeglumine in doses of 0.005, 0.05, 0.1, and 0.2 mmol/kg body weight. Two subjects received each dose. Administration of 0.1 mmol/kg resulted in a maximum liver enhancement of 149% on the gradient-echo sequence and of 90% on the T1-weighted spin-echo sequence 60 min after injection. The contrast enhancement of the liver remained virtually constant for 2 hr. The signal-to-noise ratio of the biliary tract increased from 38 to 121 after 2 hr on gradient-echo images. In addition, there was significant contrast enhancement of the kidneys. Optimal visualization of the liver parenchyma was achieved with doses of 0.05 and 0.1 mmol gadobenate dimeglumine/kg. Mild to moderate side effects such as nausea and retching, a sense of warmth at the infusion site, and transient pruritus lasting 1 min were reported by three (38%) of the subjects. The initial results of the first application of gadobenate dimeglumine in humans are encouraging because the contrast agent appears to be reasonably well tolerated at the doses appropriate for hepatobiliary imaging. Further clinical studies of this contrast agent are warranted to assess its effect on liver lesion conspicuity and the frequency with which side effects occur.

Twenty mothers who had requested regional analgesia during labour had a 32-gauge catheter inserted into the lumbar subarachnoid space. The mean time to place the catheters was 116 s (range 55-270 s) and there were no technical difficulties. Incremental diamorphine was given, up to a maximum initial dose of 0.5 mg. Analgesia was excellent in 11 mothers, good in seven and unsatisfactory in two. The duration of initial analgesia from diamorphine was 101 min (range 30-170 min). Eight mothers were able to move about during the first stage, with effective analgesia. Side effects were common: 15 mothers had pruritus, 15 had nausea or vomiting, and eight had mild sedation. No mother had a ventilatory frequency of less than 12 b.p.m. in the 12 h after the last dose of intrathecal diamorphine. Intrathecal 0.5% bupivacaine was given to 16 mothers in the first stage because the analgesia after a top-up with diamorphine became insufficient later in the labour. Fifteen mothers were pain free after bupivacaine; there was one failure. The initial effective dose of bupivacaine was between 0.25 ml and 2 ml. The maximum height of the block after bupivacaine was T9, and there was no hypotension. Nine mothers were given hyperbaric 0.5% bupivacaine 1-2 ml during the second stage; all were pain free for the procedure. The maximum force needed to withdraw the catheters was 700 g; and all catheters were removed intact. There were no post-spinal headaches.

A multicenter study was performed to determine the incidence of adverse reactions to two contrast media with similar low osmolality during cardiac angiography. The study was of a randomized double-blind design comparing ioxaglate (an ionic dimer) and iopamidol (a nonionic compound) and included 500 patients; 250 patients received ioxaglate and 250 iopamidol. There were 58 adverse reactions attributed to the contrast media in the ioxaglate group and 29 in the iopamidol group (p less than 0.001). Chest pain occurred in 11 patients in the ioxaglate group compared with 5 in the iopamidol group (p = 0.123). Nausea or vomiting was present in 20 and 2 patients, respectively (p less than 0.0003). Allergic adverse reactions, such as bronchospasm, urticaria and itching, occurred in 15 of the ioxaglate group and only 1 of the patients receiving iopamidol (p less than 0.0007). Fifty-two patients in the ioxaglate group had a known allergic history (not to contrast medium) or asthma, whereas 77 receiving iopamidol had a similar history. Seven of the 52 ioxaglate-treated patients developed an allergic adverse reaction compared with none of the 77 in the iopamidol group (p = 0.001). Of 41 patients receiving ioxaglate who were premedicated with diphenhydramine, 4 had an allergic adverse event. In the iopamidol group 45 patients received similar premedication and none had an allergic adverse reaction (p less than 0.03). Thus, this multicenter study shows that adverse reactions occur more often with ioxaglate than with iopamidol and that patients with an allergic history have a greater risk with ioxaglate therapy compared with iopamidol.

Earlier studies have suggested that epidural fentanyl improves intraoperative analgesia during cesarean section, but others have suggested that it worsens postoperative analgesia from epidural morphine. The purpose of this study was to determine whether epidural fentanyl given before epidural morphine improves the quality of intraoperative epidural anesthesia without worsening postoperative analgesia provided by epidural morphine. Sixty patients having epidural anesthesia for cesarean delivery were studied. Epidural anesthesia was established using 2% lidocaine with epinephrine 5 micrograms/mL. After delivery, either fentanyl 100 micrograms/10 mL or normal saline-control 10 mL was injected through the epidural catheter in a randomized, double-blind manner. All patients received 3.5 mg of morphine epidurally after uterine repair. After administration of the epidural study drug, there were no significant differences in the pain responses during surgery between the two groups. Patients in the fentanyl group experienced significantly less nausea and vomiting between delivery and the end of surgery than did patients in the normal saline-control group (P = 0.013). Postoperatively, visual analogue scale scores for pain, pruritus, nausea, and sedation were similar at 1, 2, 4, and 8 h in the two groups. We conclude that fentanyl 100 micrograms administered epidurally during cesarean delivery did not improve intraoperative analgesia, but significantly reduced intraoperative nausea and vomiting without diminishing the efficacy of postoperative analgesia provided by epidural morphine.

Peritonitis following urticaria on two occasions in a 46-year-old white female treated with CAPD for nine years is reported. On both occasions an episode of urticaria and pruritus occurred 24 hr before the dialysate became cloudy, and the patient experienced abdominal pain, nausea, and vomiting. The culture of the peritoneal dialysis effluent grew gamma Streptococcus with the first episode. To our knowledge this is the first report of CAPD peritonitis preceded by urticaria where the skin findings were most likely related to the peritoneal infection.
