An open study was carried out in 196 consecutive patients who had undergone orthopaedic (103) or gynaecological (93) surgical procedures to assess the effectiveness and tolerability of a single dose of 500 mg diflunisal in the relief of postoperative pain. Diflunisal was given when patients first complained of pain, and pain severity before and at intervals up to 6 hours after the dose was assessed using a 10-point analogue scale. The results showed that diflunisal was both prompt and prolonged in its effect. No pain was reported after 1 hour in 138 (71%) of the 196 patients, and after 6 hours only 13 (7%) still reported some pain. Diflunisal was equally as effective in the two groups. Side-effects were reported in 13 (7%) patients but these were ones commonly found in the post-operative situation.

In 104 premedicated patients undergoing general surgery, anaesthesia was induced either with etomidate 0.3 mg kg-1 preceded by fentanyl 1.25 or 2.5 microgram kg-1 i.v.or diazepam 0.0625 or 0.125 mg kg-1 i.v., or with thiopentone preceded by fentanyl 1.25 microgram kg-1 i.v. Despite the use of fentanyl or diazepam, the frequency of pain on injection in patients receiving etomidate was between 32% and 53%, being rated as severe in 5-20% of patients. No pain was experienced by patients receiving thiopentone. The frequency of involuntary movement was 15-35% with etomidate and 15% with thiopentone. The frequency of both pain and involuntary muscle movements was least when fentanyl 2.5 microgram kg-1 preceded the administration of etomidate. There was no significant relationship between the pain and muscle movement; three of 10 patients given etomidate into a central vein had such movements.

Seven elite boardsailors reporting nonradiating low back pain without leg pain during sailing volunteered for detailed examination. In these subjects, the onset of pain was limited to those occasions when sailing positions were held for a significant period of time, e.g., close hauled sailing or in light winds. No pain was described at any other time. The determination of possible antecedent factors was based on the results of clinical assessment, radiological evaluation, and computer tomography (CT) scanning. Apart from limited flexibility in some subjects, the clinical examination of these athletes was normal; CT changes in this group were limited to disc protrusions and bulges, and pars interarticularis defects. Despite the small number of subjects in the present report, it appears that the frequency of these problems exceeds that in the normal population. It may be possible to suggest that risk factors such as body position during prolonged sailing, particularly under light wind conditions without a harness, and limited flexibility may be associated with the radiological findings and may be implicated in the presence of low back pain, although further investigations appears warranted.

Celiac plexus block is usually performed under fluoroscopic or tomodensitometric guidance. We report on a new procedure using sonographic guidance. the patient lies in supine position. We use a real-time sonograph with a 3.5 MHz probe. On a transverse plane, the celiac axis is localized emerging from the aorta. Under local anesthesia, the tip of the spinal needle (177 mm, 22 g) is placed close to the aorta (about 5 mm) on both sides. 5 to 10 ml of 1% lidocaine, then 10 to 20 ml of absolute alcohol, are injected on each side. 21 patients (10 males, 11 females, mean age: 61.4) underwent the procedure. They presented with cancer of the pancreas in 14 cases, metastatic nodes from an extra-pancreatic tumor in 5 cases and chronic calcifying pancreatitis (CCP) in 2 cases. No pain relief was secured in 3 patients (14%). One of these presented with CCP, but endoscopic cystic diversion of a small cyst was successful in eradicating pain. Partial pain relief was secured in 5 cases (24%) and total pain relief in 13 cases (62%). No treatment-related complication was observed. We conclude that sonography is a simple and safe method of guidance in performing alcohol block of the celiac plexus. The anterior approach may prevent neurologic complications occurring with other methods of guidance using a posterior approach.

Calcitonin gene-related peptide (CGRP) was injected alone and in combination with substance P (SP) or neurokinin A (NKA) into the forearm skin and temporal muscle of human volunteers. In the skin, 50 pmol of CGRP induced a wheal response and a delayed erythema. No pain was recorded. No interaction between CGRP and SP or NKA was observed. In the temporal muscle, 200 pmol of CGRP alone did not induce pain or tenderness but, in combination with SP or NKA, CGRP elicited a significant pain sensation. It is concluded that CGRP may be involved in neurogenic inflammation and that only SP, of the three peptides present in nociceptive C fibers, seems to be of major importance in relation to cutaneous nociception. Simultaneous neurogenic release of CGRP and other neuropeptides in skeletal muscle may induce myofascial pain.

Study of the detailed pathology of the myocardium and coronary arteries in ambulatory subjects dying suddenly of coronary heart disease shows that they can be divided into two groups. In one group, there is atherosclerosis with a new vascular event involving coronary thrombosis, which initiates acute myocardial ischemia. In the other group, there is chronic high-grade stenosis due to atherosclerosis, but there is no recent vascular change; the myocardium in this group shows scarring from a previously healed infarction acting as a substrate for reentrant ventricular arrhythmias. A study of 168 consecutive cases of sudden coronary death in London showed 73.3% to have had a recent coronary thrombotic lesion, giving a ratio of 2.7:1 for patients with versus patients without new acute myocardial ischemia. The widely differing ratios reported in the literature probably reflect the patterns of case selection. Prodromal pain immediately before the onset of ventricular fibrillation in a patient without previous known coronary disease selects for a thrombotic cause and acute myocardial ischemia. Absence of pain in a patient known to have had a previous infarction selects for a primary arrhythmia on the basis of preexisting myocardial hypertrophy and/or scarring.

Celiac plexus block is usually performed under fluoroscopic or tomodensitometric guidance. We report on a new procedure using sonographic guidance. The patient lies in supine position. We use a real-time sonograph (Kontron Sigma 1 AC) with a 3.5 MHz probe. On a transverse plane, the celiac axis is localized emerging from aorta. After local anesthesia, the tip of the spinal needle (177 mm, 22 G) is placed close to aorta (about 5 mm) on both sides. 10 to 15 ml of 1 per cent lidocaine then 10 to 15 ml of absolute alcohol are injected on each side. 21 patients (10 males, 11 females, mean age: 61) underwent the procedure. They presented with cancer of the pancreas in 14 cases, metastatic nodes in 3 cases, cholangiocarcinoma in 2 cases and chronic calcifying pancreatitis (CCP) in 2 cases. No pain relief occurred in 3 patients (14 per cent). On of those presented with CCP but the endoscopic cystic diversion of a small cyst was successful to eradicate pain. Partial pain relief occurred in 5 cases (24 per cent). Total pain relief was obtained in 13 cases (62 per cent). No complication related to the treatment was observed. Sonography is a simple and safe method of guidance to perform alcohol block of the celiac plexus. The anterior approach may prevent neurologic complications related to other methods of guidance.

The purpose of this investigation was to compare the rate of absorption and clearance time of midazolam (Versed) when administered by the submucosal (SM) route), and the intramuscular (IM) route in ten healthy adult volunteers, ranging in age from 25 to 35 years. Each subject received midazolam 0.08 mg/kg, to a maximum of 5 mg, by the SM and IM routes at two week intervals. Vital signs and arterial oxygen saturation levels were monitored every five minutes throughout the 180 minute study period. Blood samples (3 ml) were collected via an intravenous line, prior to midazolam administration and at 2, 5, 10, 20, 30, 45, 60, 90, 120, 150 and 180 minutes, centrifuged and analyzed by gas-liquid chromatography. The mean absorption rates and the mean elimination times of the two routes were not significantly different. The mean peak absorption was reached at 10 minutes by the SM route (80.4 ng/ml) and at 20 minutes (92.0 ng/ml) by the IM route, with considerable individual variability. Vital signs were stable throughout the study period in all subjects with both routes. All subjects reported pain at the injection site during SM injection which continued for up to 48 hours. No pain related to the IM injection was reported.

This study examines the incidence and severity of postoperative pain after gingivectomy using one non-eugenol-containing periodontal dressing, Coe-pak (n = 76) and 2 eugenol-containing periodontal dressings, Wondrpak (n = 64) and Nobetec (n = 86). All patients were subjected to gingivectomy using 1 type of local anaesthesia (lidocaine + adrenalin) only and covering the surgical areas with either of the 3 different dressings in a randomized study. Postoperative pain was assessed on 100 mm visual analogue scales over 5 days starting immediately after surgery. No pain was reported by 22.0% of the patients after Coe-pak, 23.4% after Wondrpak and 30.2% after Nobetec. 13.2% of the patients took analgesics after Coe-pak treatment, 3.1% after Wondrpak and 1.2% after Nobetec. Mean pain score after Coe-pak was higher (P less than 0.05) than after Nobetec 2 h after operation until the morning on the 3rd postoperative day. Mean pain score after Coe-pak was higher (P less than 0.05) than after Wondrpak 3 h to 9 h after operation. No statistically significant difference was found between Wondrpak and Nobetec regarding mean pain score.

An epidural type catheter was placed in the pleural space under direct vision before the closure of the chest in 24 patients who underwent thoracotomy for various types of lung or aortic surgery. All patients received intrapleural injections of 20 ml of 0.5 per cent bupivacaine with or without epinephrine as initial pain therapy. Patients also received subsequent doses of a similar volume of 0.375 per cent bupivacaine with epinephrine 1:200,000 up to four times a day for a maximum duration of seven days. Good pain relief was achieved in patients who underwent lateral and posterior thoracotomies. No pain relief was achieved in patients who underwent anterior thoracotomy or in patients in whom there was excessive bleeding in the pleural space. Bupivacaine blood concentrations were measured in 11 patients following the initial dose of 20 ml of 0.5 per cent bupivacaine (with epinephrine 1:200,000 in five of the 11 patients). The mean peak plasma concentration of bupivacaine when used with epinephrine was 0.32 +/- 0.02 microgram.ml-1. The mean peak plasma concentrations of bupivacaine when used without epinephrine was 1.28 +/- 0.48 microgram.ml-1. Our present data show that intrapleural analgesia is useful in the management of postoperative pain in patients who undergo thoracotomy. Our data also show that there is a significant decrease in peak plasma concentrations of bupivacaine when epinephrine is added to the solution (P less than 0.05).
