A single-blind, randomized clinical trial was carried out to compare the analgesic effectiveness in patients with renal colic of single intramuscular doses of diclofenac sodium (75 mg) versus a dipyrone (1 g)/spasmolytics combination, and diclofenac sodium (75 mg) versus pethidine (75 mg). The first study involved three centres, the second study one centre. In total, 107 patients were treated with diclofenac sodium, 85 with dipyrone/spasmolytics, and 25 with pethidine. Assessments were made during the first hour after drug administration of the degree of pain relief, the severity of pain using a visual analogue scale, and the duration of analgesia. A global assessment of treatment efficacy was made by the participating physicians at the end of the study period. Patients treated with diclofenac sodium showed an earlier onset of analgesia and a higher incidence of total pain relief compared to those treated with dipyrone/spasmolytics or pethidine. Although the mean duration of analgesia was only slightly greater in the diclofenac sodium group than in the dipyrone/spasmolytics group, a significantly longer effect was seen when diclofenac sodium was compared with pethidine (p less than 0.01). Pain severity assessments revealed that diclofenac sodium caused a significantly greater improvement in pain after 60 minutes compared to dipyrone/spasmolytics (p less than 0.05) and after 30 minutes compared to pethidine (p less than 0.05). Global efficacy assessments by the physician rated diclofenac sodium as significantly superior to dipyrone/spasmolytics (p less than 0.01) and pethidine (p less than 0.001). Moreover, diclofenac sodium was better tolerated than either of the comparative treatments. The results indicate that intramuscular diclofenac sodium is a useful alternative to the drugs commonly used in India in the treatment of renal colic.

A randomized double blind study was carried out to determine whether alkalization of a 0.25% bupivacaine solution in a fentanyl-bupivacaine mixture hastened the onset, and increased the duration and quality, of extradural analgesia during labour. The study included 120 women with uncomplicated full-term gestation. Prior to the extradural injection, 0.1 ml of either 8.4% sodium bicarbonate or normal saline was randomly added to 20 ml of 0.25% bupivacaine. The patients were given 75 micrograms fentanyl with 12 ml of either alkalized or unaltered bupivacaine. Data for analysis were obtained in 106 parturients (bicarbonate group n = 54; control group n = 52). The pH of alkalized and unaltered bupivacaine were 7.07 +/- 0.01 and 5.56 +/- 0.01 respectively. There were no statistically significant differences between the bicarbonate and control groups with regard to the speed of onset of analgesia (7.08 +/- 0.7 min vs. 6.78 +/- 0.6 min), its duration (123.6 +/- 10.7 min vs. 113 +/- 6.6 min), and the number of cases of inadequate pain relief (6 and 3 respectively). The rate of maternal adverse effects, and neonatal status, were similar in both groups. It can be concluded that alkalizing a 0.25% bupivacaine solution in a fentanyl-bupivacaine mixture for epidural analgesia in labour has no clinical value.

Increasing the pH of 2% chloroprocaine (CP) with sodium bicarbonate to pH 7.7 hastens the onset of epidural analgesia. The purpose of the present study was to determine the effect of pCO2 on the onset of epidural analgesia with CP buffered to a constant pH 7.7. Four groups consisting of ten patients each were studied: C, control, commercial CP (pH 4.35); B, CP buffered with sodium bicarbonate (pH 7.7); T, CP buffered with tromethamine (pH 7.7), and BT, CP buffered with sodium bicarbonate and tromethamine (pH 7.7). All epidural catheters were placed at the L2-3 or L3-4 interspace using a loss-of-resistance technique with air with each patient in a sitting position. The pH and pCO2 of each local anesthetic solution were measured as well as the onset and duration of analgesia. The study groups did not differ with respect to demography or entry characteristics. There were intergroup differences in the pCO2 values of the study solutions as follows: Group 1 (C), 11.8 +/- 1.5 mmHg; 2 (B), 113.0 +/- 1.4 mmHg; 3 (T), 3.0 +/- 0.3 mmHg, and 4 (BT), 74.1 +/- 1.0 mmHg, respectively. The time to the onset of analgesia was significantly faster in Group 2 (B; 2.7 +/- 0.8 minute), while the onset of analgesia was significantly slower for Group 3 (T; 5.4 +/- 0.4 minute) than either Group 1 (C; 4.2 +/- 0.8 minute) or Group 4 (BT; 3.4 +/- 0.3 minute). Regression analysis revealed that the onset times of the buffered solutions were significantly related to pCO2 (r2 = 0.81).(ABSTRACT TRUNCATED AT 250 WORDS)

A double-blind, crossover study was undertaken in general practice to compare the efficacy and tolerability of a new controlled-release indomethacin with sustained-release diclofenac sodium in patients with osteoarthritis. Eighty-four patients were randomly allocated to receive controlled-release indomethacin tablets (75 mg) or sustained-release diclofenac sodium tablets (100 mg) at night for a period of 4 weeks before being crossed-over to receive the alternative treatment for a further 4 weeks. Pain scores for day and night, duration of morning stiffness, requirement for escape analgesia, and treatment preference were similar for both treatments. There was no significant difference between treatments for incidence and severity of side-effects. It was concluded that controlled-release indomethacin tablets (75 mg) given as a single night-time dose were as efficacious and well tolerated as sustained-release diclofenac sodium (100 mg).

The efficacy and tolerability of a new, controlled-release indomethacin (75 mg) tablet was compared to that of a sustained-release diclofenac sodium (100 mg) tablet in 84 patients with rheumatoid arthritis. The study was designed as a double-blind, double-dummy crossover trial, patients being allocated at random to receive 1 active tablet and 1 placebo tablet of the alternative medication at night for 4 weeks before being crossed over to the alternative treatment for a further 4 weeks. Patient and clinical assessments on entry and at the end of each treatment period showed that pain scores for day and night, duration of morning stiffness, requirement for escape analgesia (paracetamol) and treatment preference were similar for both treatments. Both preparations also significantly improved the degree of joint tenderness compared to baseline (p less than 0.001), as measured by a modified Ritchie Articular Index. Incidence and severity of side-effects were comparable, with a significant improvement in degree of constipation reported for both treatments compared to baseline (p less than 0.05). The incidence and severity of headache was statistically significantly worse (p less than 0.05) for controlled-release indomethacin; however, there was no difference in any other parameter of tolerability. It was concluded that controlled-release indomethacin tablets (75 mg) given as a single night-time dose were as efficacious and well tolerated as sustained-release diclofenac sodium (100 mg).

A randomized double-blind study of parturients after Cesarean section was undertaken to assess the efficacy of the combination of single dose intramuscular diclofenac sodium and low dose epidural morphine (EM) for postoperative analgesia. 50 parturients under epidural anesthesia were divided into 2 treatment groups: group A received 2 mg EM 30 min after the last dose of lidocaine and 3 ml normal saline i.m. at recovery room; group B received the same EM and 75 mg diclofenac i.m. postoperatively. Pain scores were compared at the 2nd, 4th, 8th, 12th, 18th, and 24th h. Results showed that group B was superior to group A in analgesic quality from the 8th h and thereafter (P less than 0.05) and 100% patients in group B were in the excellent to good analgesia categories at the 8th and 12th h record compared to 92% and 72% patients in group A respectively. Side effects were similar in both groups. The combination of NSAIDs with low dose EM could improve the analgesic quality after Cesarean section.

After elective hospitalization, eleven healthy young women developed symptomatic hyponatremia that was rapidly followed by polyuria, hypernatremia, hyperglycemia, and death. The patients were 30 +/- 2 years old (+/- SE) with initial serum sodium of 140 +/- 1 mmol/L. They all awoke from analgesia but, 32 hours after completion of the procedure, they went from alertness to respiratory arrest in less than 1 hour. At this time, serum sodium was 116 +/- 2 mmol/L and blood glucose was 6.7 +/- 0.7 mmol/L. Without treatment for the hyponatremia, urine output spontaneously increased from 38 to 689 mL/h and urine osmolality fell from 546 to 83 mmol/kg body weight. Over the next 51 hours, blood glucose rose to a high of 24.1 +/- 2.5 mmol/L while serum sodium rose to a high of 167 +/- 2 mmol/L. None of the patients regained consciousness. At autopsy, all patients had cerebral edema with herniation along with hypoxic brain damage. The pituitary showed infarction of both anterior and posterior lobes in 7 of 7 patients examined, while 8 of 11 had necrosis of the medulla and 8 of 8 patients examined had hypothalamic necrosis. All had normal pancreas and kidneys at autopsy. Soon after respiratory arrest, all of the patients developed fixed, dilated pupils that often led to the diagnosis of brain death. Autopsy showed compression of the third cranial nerve (oculomotor) because of cerebral herniation. Thus, all of the patients were diagnosed as being brain dead when some may have been saved. These data suggest that in otherwise healthy young women, untreated symptomatic hyponatremia may lead to brain edema, cerebral herniation, and infarction of pituitary and hypothalamus, resulting in central diabetes insipidus and mellitus.

There have been few major complications of percutaneous nephrostolithotomy (PNL) reported. We recently experienced cardiac arrest during PNL under epidural anesthesia. The patient was a 52 year old man weighing 64 kg who had been suffering from right renal pelvic stone for years. He was scheduled for PLN under epidural anesthesia. Analgesia was obtained to the level of Th6. The operation proceeded uneventfully for about 60 min. By this time, he suddenly complained nausea, and hypotension with bradycardia occurred. Blood pressure and pulse rate returned immediately to the normal level by IV atropine and ephedrine. But after three minutes, blood pressure and pulse rate went down again. This hypotension with bradycardia was unresponsive to epinephrine, calcium chloride and sodium bicarbonate. This was followed by asystole. Resuscitation was successful with the addition of epinephrine, calcium chloride, and sodium bicarbonate about 15 min after cardiac massage had started. The patient was, on the fifth postoperative day, with no evidence of impairment of renal, cardiac and respiratory functions but a slight impairment of neurologic function. Several possible causes for this cardiac arrest and anesthetic management of percutaneous nephrostolithotomy are discussed.

Hemodynamic response to induction to anesthesia and tracheal intubation was assessed in 132 patients with gastric cancer divided into groups depending on the method of induction. Group I was administered thiopental sodium at a dose of 4-5 mg/kg, group II--thiopental sodium at the same dose and fentanyl (1.5 micrograms/kg), group III--thiopental sodium at the same dose with local laryngeal anesthesia using a 10% lidocaine solution, group IV--propanidid (4-5 micrograms/kg), and fentanyl (1.5 micrograms/kg), group V--thiopental sodium at the same dose and fentanyl (3-5 micrograms/kg), group VI--diazepam (15-20 mg) and fentanyl (3-5 micrograms/kg). Tracheal intubation followed dithylin injection without premedication. It has been established that adequate analgesia achieved by fentanyl (3-5 micrograms/kg) administration is the main factor that has a stabilizing effect on circulation during induction to anesthesia involving tracheal intubation. Lower drug doses and local laryngeal anesthesia proved effective in less than one third of patients. Circulatory response to pressor-depressor induction factors depends significantly on the baseline cardiac output and BP values and to a lesser extent on circulating blood volume (CBV) deficiency. Preoperative volume expansion with 12-15 ml/kg infusions stabilizes circulation parameters even in the absence of CBV deficiency, which confirms the functional nature of hypovolemia in patients with gastric cancer.

Hysterosalpingography provides important information in the evaluation of infertility but is generally considered an uncomfortable and painful procedure. We evaluated various analgesics for decreasing or eliminating the discomfort from this procedure. Two types of analgesia were required to give maximum pain relief during and after the examination in the 180 patients evaluated. The best results were achieved with a combination of naproxen sodium, 550 mg, given orally two hours before the examination, and 20% benzocaine, applied to the cervix.
