In the acute experiment six healthy volunteers were given orally two doses of lithium chloride, 16 and 32 mmol, and placebo sodium chloride 32 mmol in a double-blind standardized procedure, with a 1-week interval between treatments. Compared to sodium, lithium produced a decrease in subjective well-being, decrease of skin conductance fluctuations, and increase in plasma calcium concentrations. Dose-related effects were maximal at the first hour after ingestion, decreasing or disappearing at 3--5 h. Most effects did not correlate with plasma or erythrocyte lithium concentrations, but drug effects and feelings of nausea were highly correlated. Accordingly, most acute effects seemed due to peripheral drug effects. In the chronic experiment six healthy volunteers were given orally 16 mmol of lithium chloride or sodium chloride (placebo) twice a day for 1 week in a double-blind standardized procedure with a 2-week interval between treatment weeks. Compared to placebo, lithium produced feelings of subjective impairment, an increase in EEG slow waves and of auditory evoked response variability, a deficit in long-term memory, and an increase in plasma magnesium concentrations. Most lithium effects did not correlate with plasma or erythrocyte lithium concentrations.

3 cases of intravascular spill of hyperosmolar urea during induced midtrimester abortion are reported. In each case 80 gm of urea had been infused. Although urea may pose less concern than hypertonic sodium chloride because of its ability to readily cross cell membranes and its action as an osmotic diuretic, inadvertent intravascular spill can produce symptoms that include nausea, headache, sensations of warmth, and intense uterine cramping. Also, abnormal blood pigments may occasionally be noted in the urine. The 3 patients were 23, 20, and 24 years old, all para 0. The symptoms generally subsided after 30 minutes, and serum and urinary abnormalities returned to normal within 24 hours. Treatment included iv hydration, careful monitoring of fluid/electrolyte balance and renal function, and avoiding the use of oxytocic agents for at least 24 hours. The 3 patients eventually underwent successful abortions, 1 with intraamniotic prostaglandin F2 alpha (PGF2a), and 1 with urea-PGF2a abortion, without further complications.

Two college students developed symptoms of poisoning following ingestion of a salt solution during a college physiology laboratory exercise. Symptoms included nausea, vomiting, diarrhea, and altered consciousness. The ingested solution was identified as isotonic buffered saline containing sodium azide in a concentration of 1.0 g/L. The solution was commercially prepared for instrumentation use only and was used inadvertently for the exercise instead of freshly preparing sodium chloride in water. One student drank three sips of the solution and survived. The other student drank 700 to 800 mL and over several days became progressively ill, suffering myocardial damage and cardiac dysrhythmias, and, finally, died. Toxicologic studies confirmed the presence of azide in an antemortem urine sample from the deceased. Sodium azide is an uncommon but potent poison which can cause serious illness and death.

A 37 year old black female presented with congestive cardiac failure, 2 months postpartum. She developed spontaneous hypoglycaemia and symptoms of acute adrenal crisis (hypotension, nausea, abdominal pain and tachycardia with small thready pulse), which responded to i.v. dextrose, sodium chloride and hydrocortisone. Biochemical investigations revealed low serum cortisol and plasma adrenocorticotrophic hormone (ACTH) levels. The patient initially showed an impaired cortisol response to intramuscular aqueous tetracosactrin, but an exuberant response after priming with intramuscular tetracosactrin depot. These findings, together with the normal remaining pituitary function, led us to conclude that this patient had isolated ACTH deficiency associated with congestive cardiac failure and acute adrenal crisis.

Supravesical urinary diversion using a jejunal conduit may be associated with hyponatremia, hypochloremic-acidosis, hyperkalemia, azotemia, and a clinical picture of nausea, vomiting, dehydration, muscular weakness, elevated temperature, and lethargy. This syndrome is secondary to the loss of sodium chloride into the urine passing through the conduit and absorption of potassium and urea from it. Treatment and prevention of this syndrome consist of adequate supplements of sodium chloride and hydration. Intravenous hyperalimentation as the precipitating factor of a severe form of this syndrome and its successful management are described. The pathophysiology of the jejunal conduit syndrome is also discussed. Great selectivity and extreme caution are recommended with respect to the use of intravenous hyperalimentation in patients with jejunal conduits.

This prospective, double-blind study examined the antiemetic effectiveness of the addition of droperidol to a morphine solution for use in patient-controlled analgesia in a group of 50 patients undergoing elective lumbar laminectomy. The addition of 20 mg droperidol to 120 mg morphine in 60 ml saline given by a Baxter 'Infusor' patient-controlled analgesia device reduced the incidence of vomiting as compared to the addition of sodium chloride from 42.8% to 12.5% (p = 0.028) and of nausea from 71.4% to 29.2% (p = 0.005). The proportion of patients requiring rescue antiemetic therapy was reduced from 47.6% to 16.7% (p = 0.025) and the time interval to the first use of rescue antiemetic agent was significantly prolonged (p = 0.029). The use of droperidol was associated with an increased degree of sedation during the first 12 h after operation.

Forty-five ASA physical status I volunteers, divided in three groups of 15 each, received intravenous regional anesthesia (IVRA) of the upper limb with 40 mL meperidine 0.25%, lidocaine 0.5%, or 0.9% sodium chloride (isolated ischemia) by random allocation. Using a double-blind method, the onset and recovery of sensory block was tested at six sites of the forearm and hand. The onset of complete motor block was also assessed. The symptoms after deflation of the tourniquet were recorded. The onset of block, as determined by pin-prick touch, and cold was significantly faster in the meperidine group (P < 0.001) than in the saline group, but also slower (P < 0.001) than in the lidocaine group. After the tourniquet was deflated, recovery occurred in reverse order. A complete motor block was noted in all volunteers from the meperidine and lidocaine groups, but in only 11 cases from the 0.9% sodium chloride group (P < 0.01). In the meperidine group, motor block developed concomitantly or prior to sensory block. There was a significant increase in the incidence of dizziness, nausea, and pain at the injection site in the meperidine group in comparison with the lidocaine group. We conclude that meperidine has local anesthetic action on the peripheral nerve in vivo, but that its single use for IVRA should be a second choice for patients allergic to local anesthetics.

An opioid-sparing effect of alpha-trinositol (D-myo-inositol 1,2,6-trisphosphate) following cholecystectomy in otherwise healthy patients was suggested by a pilot study. In order to verify this result, pain, pain relief and nausea were studied in patients undergoing elective cholecystectomy by minilaparotomy. The patients were randomized using double-blind design to receive an intravenous infusion of either alpha-trinositol or sodium chloride (placebo) for eight hr after the operation. Pain, pain relief and nausea were evaluated up to 72 hr after surgery using visual analogue scales (VAS). Rescue analgesic medication was registered. As a further measure of pain and/or restrictions caused by pain, peak expiratory flow, walking distance and pressure pain thresholds were assessed. There was no difference between the groups in ratings of pain, pain relief, nausea or amount of analgesic medication given. The mean ratings of pain were significantly higher in the sitting position compared to lying down. Neither pressure pain thresholds, nor the walking distance differed between the patients given alpha-trinositol and placebo, respectively. There were significant reductions of peak expiratory flow and of pressure pain thresholds under both costal margins up to 72 hr after surgery compared to presurgery values. As a conclusion, no analgesic effect of alpha-trinositol at the dosage used was observed in the postoperative patients studied.

To evaluate the analgesic efficacy of local anesthetic infiltration, 20 parturients scheduled for elective minilaparotomy and bilateral tubal ligation with either spinal or epidural anesthesia participated in this prospective, randomized, controlled, double-blind trial. All patients received intravenous (iv) metoclopramide 10 mg and ketorolac 60 mg intraoperatively, as well as preincisional infiltration of the infraumbilical skin incision with 0.5% bupivacaine. Infiltration of bilateral uterine tubes and mesosalpinx was performed either with 0.5% bupivacaine (n = 10) or isotonic sodium chloride solution (n = 10). Intravenous meperidine (25 mg every 3 minutes as needed) was given to treat pain in the postanesthesia care unit (PACU). The total amount of meperidine administered in the PACU was significantly larger in the saline group than in the bupivacaine group. Pain scores at 30, 45, 60, 75, and 90 minutes postoperatively and on the 7th postoperative day were significantly lower in the bupivacaine group than in the saline group. During tubal ligation, infiltration of uterine tubes and mesosalpinx with 0.5% bupivacaine significantly enhanced analgesia both immediately postoperatively and on the 7th postoperative day compared with infiltration with sodium chloride. In conclusion, this study proved that during bilateral tubal ligation with either spinal or epidural anesthesia, preemptive analgesia using iv ketorolac, iv metoclopramide, and infiltration of the incised skin and uterine tubes with 0.5% bupivacaine can eliminate pain, nausea, vomiting, or cramping and maintain good analgesia for 7 days postoperatively.

A prospective, randomized, double-blind and placebo-controlled study was conducted to assess the effectiveness of i.v. administration of 6% hydroxyethyle starch solution (HES) in preventing moderate and severe ovarian hyperstimulation syndrome (OHSS) in patients in an in-vitro fertilization programme. A total of 101 women who had serum oestradiol concentrations >1500 pg/ml and/or more than 10 follicles on day of human chorionic gonadotrophin (HCG) administration were recruited into two groups: HES group (n = 51) received 1000 ml 6% HES; and the placebo group (n = 50) received 1000 ml of sodium chloride 0.9% solution at the time shortly after embryo transfer. Follow-up examinations 7 +/- 1 and 14 +/- 1 days after embryo transfer included transvaginal ultrasound (diameters of each ovary and maximum cysts, number of cysts, ascites), blood tests (serum oestradiol, progesterone, beta-HCG, C-reactive protein, blood count, plasma proteins, electrolytes, kidney function tests) and evaluation of abdominal pain, nausea, diarrhoea, abdominal swelling and weight gain. Only one moderate OHSS developed in the HES group whereas seven moderate-severe cases were observed in the placebo group (P = 0.031). Furthermore, serum oestradiol concentration, leukocyte count, increase in abdominal circumference and weight gain 14 days after embryo transfer were significantly higher in the placebo group. There were no differences between the two groups in terms of age, oestradiol concentration and number of follicles at time of HCG injection. Administration of 6% HES prevents the development of moderate-severe OHSS in risk patients.
