Three anaesthetic premedication regimens have been compared by double-blind controlled trial in 158 patients undergoing day-case surgery for varicose veins or hernia. Atropine plus droperidol was superior to atropine plus diazepam or atropine alone in lessening nausea and vomiting and in reducing the need for postoperative analgesia.

Oral naproxen in doses of 500 mg and 750 mg daily was compared with oral indomethacin, 75 mg daily, in a double-blind, completely randomized study of patients with post-operative pain after out-patients varicose vein surgery. Altogether, 120 patients were studied. In the study 750 mg naproxen proved to be equal in respect of analgesic efficacy to 75 mg indomethacin, and it was clearly superior to 1500 mg acetylsalicylic acid. Naproxen, 500 to 750 mg daily, afforded adequate post-operative analgesia in 98% of patients. The side-effects were mild. On the basis of the study, naproxen can be recommended as a pain-relieving drug after minor surgery, particularly when an antiphlogistic effect is also desirable.

Malignant hyperthermia syndrome developed during epidural analgesia in 25-year-old female to be operated on for haemorrhoidal varices. After premedication with diazepam and atropine epidural analgesia was started with lidocaine 300 mg and bupivacaine 50 mg. Signs and symptoms of malignant hyperthermia syndrome appeared 30 min. later, with muscle rigidity, hyperpyrexia 41.5degrees C, and loss of consciousness. Treatment alleviating the syndrome was applied as indicated in this complication. Full recovery was obtained.

Etidocaine 1% and bupivacaine 0.5% (both with adrenaline 5 mug/ml) have been compared in a double blind study in epidural analgesia. Time of onset, duration, recession of analgesia and intensity as well as frequency of motor blockade were recorded in a selected group of patients undergoing varicose vein stripping. The onset of action of etidocaine was more rapid. Duration, recession and intensity of analgesia were similar for the two drugs. The main difference between them was that etidocaine produced a higher frequency and greater intensity of motor blockade.

Ropivacaine, congenerate to bupivacaine and mepivacaine has been widely studied in laboratory animals, but there have been few investigations of its efficacy in human epidural anesthesia and peripheral nerve blocks. The aim of this study was to compare the three long-acting local anesthetics (bupivacaine 0.75%, ropivacaine 1% and etidocaine 1%) and to try, with reference to previous studies, to make some statement about the equipotency of ropivacaine relative to bupivacaine and etidocaine. METHODS. In a double blind randomized study, epidural anesthesia was carried out with 20 ml bupivacaine 0.75% (n = 24) and ropivacaine 1% (n = 21). Following this study epidural anesthesia was carried out with 20 ml etidocaine 1% (n = 20) in an open study. Patients with ASA I or II were enrolled in the study. All patients were scheduled for varicose vein stripping. Male and female patients aged 18-70 years and weighing 50-100 kg were included in the study. Patients were all placed in a sitting position, after which the epidural space was identified by the "loss of resistance" technique and a midline approach, at the L-3/4 interspace. Injections of 3 ml of the local anesthetic were given, followed by the remainder of the local anesthetic at 10 ml/min 1 min later. Following injection patients were immediately positioned supine. Analgesia was determined by the pin-prick method and motor blockade was assessed according to the Bromage scale. Heart rate and blood pressure were monitored until 3 h after injection. RESULTS. The latency of analgesia for the first blocked segment (T 12 for bupivacaine and ropivacaine and L-1 for etidocaine) was 6.0 min for bupivacaine 0.75, 5.5 min for ropivacaine 1%, and 5.2 min for etidocaine 1%, and the highest thoracic dermatome (T 5 for bupivacaine, T 4 for ropivacaine and T 7 for etidocaine) was reached after 24 +/- 10, 26 +/- 9, and 30 +/- 18 min for bupivacaine, ropivacaine, and etidocaine, respectively. The duration of sensory anesthesia at the T 10 dermatomal level was 257 +/- 102, 278 +/- 67, and 191 +/- 86 min for bupivacaine, ropivacaine, and etidocaine, respectively. The two-segment regression time was 199 +/- 80 min for bupivacaine, 201 +/- 52 min for ropivacaine, and 174 +/- 81 min for etidocaine. The total duration of sensory block was 340 +/- 103 min for bupivacaine, 428 +/- 65 min for ropivacaine and 223 +/- 62 min for etidocaine, respectively. In the ropivacaine and bupivacaine groups sensory anesthesia was considered adequate for surgery in all cases but one in each group; in the etidocaine group, however 60% of the patients showed inadequate analgesia and all these patients (12/20) required additional analgesics. Bupivacaine achieved an average of motor block 2.1, ropivacaine 2.3, and etidocaine 2.4. CONCLUSION. The results of this study indicate that ropivacaine is an effective local anesthetic agent. Its potency is about equal to that of bupivacaine and much higher than that of etidocaine...

A method of anaesthesia for surgical treatment of varicose veins is presented. This consists of a combination of propofol and three-in-one blockade. In a non-blind, non-randomised series, this method was accepted just as well as epidural analgesia or general anaesthesia. The method is recommended for outpatient surgical treatment of varicose veins on account of rapid waking of the patients, reduced need for observation after anaesthesia and reduced pollution with anaesthetic gases in the operation theatre.

Pain in the muscles and the feeling of tension in the lower legs along the varicose veins brings many patients, especially women to an operation, usually after previous attempts of conservative treatment. The aim of the work was to present the choice of analgesia for the operation of the veins of the lower limbs with the control of the post-operative analgesia. The methods included two groups of patients. One group received halothane inhalation anaesthesia in combination with nitrous oxide and oxygen, and the other ketamine hydrochloride anaesthesia applied intravenously. Postoperative pain was graded as strong, medium, mild, and painfree state. The pain intensity was assessed for each patient by the hours, and by multiplying the obtained score by the number of patients, we got the total pain scores. The pain relief 1, 2, 3, and 4 hours after the administration of propoxiphen napsilate with paracetamol was calculated according to the formula: Br = Bo-B1 (2,3,4). As compared to the placebo, we got p.o.05 in favour of the active substance after ketamine hydrochloride anaesthesia. The results have shown that postoperative pain was much lower in the group of patients who had ketamine hydrochloride anaesthesia, what together with increased oxygen saturation during anaesthesia leads to the conclusion that this anaesthesia is appropriate for operations on the veins of the lower limbs because it ensures postoperative analgesia and oxygenation without oxygen inhalation. This is important because in the region attacked by varicosity the tissue metabolism is disturbed, oxygenation decreased and the values of pCO2 increased, frequently followed by skin atrophy, lower limb edema and lymphostasis.

Colonic affectation in the context of acute pancreatitis is undoubtedly a rare complication to judge from the number of cases reported in the literature, but its appearance is increasing, perhaps because it is receiving more attention. The "infrequent" complications of so-called acute pancreatitis range from massive necrosis of the colon to fistula of the transverse colon, colonic stricture as a chronic manifestation and finally, colonic varices as a sign of segmental portal hypertension due to involvement of the mesenteric portal axis. A retrospective study was made of 6 cases treated in our General and Digestive Surgery Department and the literature on this etiopathogenic situation was reviewed to study the clinical manifestations, diagnosis and treatment of these uncommon complications. We propose minimal catheter jejunostomy as a technique for the prevention and treatment of possible complications, with epidural analgesia of these patients.

A double blind clinical trial was carried out on randomised groups of 20 patients each undergoing surgery for varicose veins to compare the actions of etidocaine 1% and bupivacaine 0.5% and 0.75% with adrenaline 1:200.000. Bupivacaine 0.75% and etidocaine 1% were found to be equipotent, with a rapid onset and long duration of anaesthesia, and a comparable degree of profound motor block. The latency period of Etidocaine was markedly increased in the L V and S I segments, probably due to its high fat solubility. 0.5% bupivacaine, compared to the other preparations, showed significantly less motor block and duration of analgesia. Unlike other investigators, "spotty-analgesia" was not found in this series.

The efficacy of mild analgesics after 160 various superficial operations was studied by comparing intravenous lysine-acetylsalicylate (LAS) 1.8 g, Litalgin 4 ml (metamizole = dipyrone 2.0 g+ pitophenone 8.0 mg) or paracetamol 0.5 g to oxycodone 4 mg. At 15 min postdrug, oxycodone 4 mg had the best peak effect but this significant (P less than 0.05) difference to mild analgesics disappeared at 30 min, and thereafter all test analgesics showed an equally low effect. Two-thirds of the patients anaesthetized without peroperative analgesics needed pain relief when recovering from superficial surgery. The need for pain relief was lowest after varicose vein operations 40% of the patients as compared to about 70% after other types of superficial surgery. In 42% of the patients requiring pain relief, the test analgesics alone gave sufficient pain relief. The rest needed an additional 5 mg of oxycodone, on average, to be comfortable. The combined use of mild analgesics and oxycodone for adequate pain relief did not seem to reduce the postdrug sedation as compared to oxycodone alone. The results indicate that in traditional clinical dosages LAS, dipyrone or paracetamol can substitute about 5 mg oxycodone but offer sufficient analgesia only in about 40% of the patients recovering from superficial surgery.
