Does clonidine 50 microg improve cervical plexus block obtained with ropivacaine 150 mg for carotid endarterectomy? A randomized, double-blinded study.

STUDY OBJECTIVE: To evaluate the effects of adding 50 microg clonidine to 150 mg ropivacaine for superficial cervical plexus block in patients undergoing elective carotid endarterectomy (TEA). DESIGN: Randomized, double-blind study. SETTING: Departments of Anesthesia and Vascular Surgery of a university hospital. PATIENTS: 40 ASA physical status II and III patients undergoing elective TEA during superficial cervical plexus block. INTERVENTIONS: Superficial cervical plexus block was placed using 20 mL of 0.75% ropivacaine alone (Ropi group, n = 20) or with the addition of 50 microg clonidine (Ropi-Clonidine group, n = 20). If required, analgesic supplementation was given with local infiltration with 1% lidocaine and intravenous fentanyl (50-microg boluses). Nerve block profile, need for intraoperative analgesic supplementation, and time to first analgesic request were recorded. MEASUREMENTS AND MAIN RESULTS: Median (range) onset time was 10 minutes (5-25 min) in the Ropi group and 5 minutes (5-20 min) in the Ropi-Clonidine group (P < 0.05). Intraoperative consumption of both 1% lidocaine and fentanyl was higher in patients of the Ropi group (15 mL [0-25 mL] and 250 microg [50-300 microg]) than in patients of the Ropi-Clonidine group (8 mL [0-20 mL] and 0 microg [0-150 microg]; P < 0.05 and P < 0.05, respectively). First postoperative analgesic request occurred after 17 hours (10-24 hrs) in the Ropi group and 20 hours (10-24 hrs) in the Ropi-Clonidine group (P > 0.05). CONCLUSIONS: Adding 50 microg clonidine to 150 mg ropivacaine for superficial cervical plexus block shortened the onset time and improved the quality of surgical anesthesia in patients undergoing elective TEA.

Neuropathy as the only symptom of common carotid artery spontaneous rupture. Case report.

We describe a case of a false aneurysm of the common carotid artery, caused by spontaneous carotid rupture, with atypical clinical presentation. The patient came to the our Hospital complaining of left shoulder pain and functional impairment of her left arm, during the past 20 days. The diagnostic work-up, color Doppler ultrasound, MR and angiography, evidenced a cervical false aneurysm; the electromyography showed denervation of the deltoid muscle, caused by cervical nerve roots compression. The therapeutic stages were initially an endovascular stent placement; then a surgical stage with evacuation for the hematoma and reconstruction of the carotid artery with saphenous graft.

[Consumption coagulopathy associated with a case of an abdominal aortic aneurysm].

Consumption coagulopathy with clinical symptoms reveals aortic arterial aneurysms in less than 5% of cases. The authors report a case of abdominal aortic aneurysm: surgical repair is able to remove the hemostasis abnormalities for a long time. Implications of the consumption coagulopathy are analyzed: diagnosis, preoperative correction of the coagulopathy, surgical technique.

Morphological changes of human pulmonary-artery endothelial cells after 12-hours hypothermic storage in organ-preservation solutions.

Pulmonary endothelial cells are known to be fundamental for lung preservation and one of the most serious limiting factors observed during transplantation is the stress to which these cells are subjected. On this premise, strenuous efforts should be made to select and employ the preservation solution best able to prolong ischemia time and thus prevent cytotoxic effects. The aim of this study was to identify the solution with minimum toxicity on endothelial cells. For this purpose, we analysed the noxious effect of solutions such as Euro Collins (ECS), Belzer (UWS) and Low-potassium Dextran (LPD) on endothelial cells after 12 hours of incubation at 10 degrees C. For each solution, we examined the modifications produced on the nuclei, mitochondria and cellular wall of human pulmonary-artery endothelial cells by transmission electron microscopy and recorded the results on an ultrastructural grading scale. As regards morphological alterations incompatible with cell life, the most cytotoxic solution proved to be ECS. UWS and LPD, on the contrary, appeared to preserve cells relatively well, and no perceptible difference was observed between the two solutions. In conclusion, it is interesting to note that although ECS is widely used for lung preservation, the results of our study indicate that a 12 hours at 10 degrees C in this solution may exert adverse effect on pulmonary endothelial cells.

A new extracellular type solution for lung preservation: "in vitro" comparison with Beltzer, low potassium Dextran and Euro-Collins solutions by means of human lung fibroblasts.

UNLABELLED: The attempt to synthesise efficacious solution to prolong lung preservation is, at present one of the most interesting challenges in transplant research. Recently, several issues emphasise the central role of ionic composition of lung-flush solutions, underlining, however, that colloid-free solutions are clearly detrimental. We have been studying a complex extracellular type solution (SPAL UP) synthesised to minimise the pathological events that occur during both preservation and reperfusion period. We report the results of toxicity of SPAL UP on normal human fibroblasts obtained from foetal lung (WI-38). WI-38 cells were seeded at 1.4 x 10(4)/cm2 in disposable plastic 12-well plates. After 3 days, cells were incubated in SPAL UP, Beltzer (UWS), Low Potassium Dextran (LPD) and Eurocollins (ECS) solutions for 6 hours at 10 degrees C. Cellular viability was evaluated by the rate of protein synthesis exploiting the incorporation of 35S-Methionine (2 microCi/ml) in growth medium with 10 mM unlabelled Methionine during 30 minutes incubation at 37 degrees C. The results were expressed as nmol. 35S-Methionine/mg of proteins/minute, and presented as means +/- SD of data of three (n = 3) well for each solution studied. RESULTS: the viability at time 0 before incubation (considered as control) was 1.65 +/- 0.1; after hypothermic preservation the data were respectively as follow: SPAL UP 0.51 +/- 0.09; UW 0.24 +/- 0.02; ECS 0.19 +/- 0.01; LDP 0.19 +/- 0.05. CONCLUSIONS: in this "in vitro" model SPAL UP solution provides a significantly (p < 0.05) better cell preservation than regular UW, ECS and LPD solutions.

Hepatic artery aneurysm: an ever present danger.

Hepatic artery aneurysms are infrequent vascular lesions, difficult to diagnose preoperatively manifesting themselves usually by acute rupture. We report our experience in both diagnosis and surgical treatment of 3 cases. The selective angiograph of the celiac tripod and of superior mesenteric artery, is an indispensable means able, not only to put forward a certain diagnosis, but also to supply precious notions on the possibilities of compensation on the side of the collateral circle and of consequence, to suggest operative tactics. Surgical management may range from the simple binding to the reconstruction of the hepatic arterial axis by means of prosthesis grafts and if possible to the simple excision and termino-terminal regraft.

[A middle esophageal ring].

The Authors, having observed a case of middle oesophageal web giving rise to severe dysphagia, discuss the aetiopathogenesis, the diagnosis and therapy of these rare oesophageal lesions. Because of its pathological feature, the reported case was succesfully treated by surgical resection of the ring, using a transthoracic approach.

[Surgical treatment of cancer of the pancreas].

A series of 145 patients with cancer of the pancreas is presented. Radical surgery was performed in 23 cases. An assessment is made of anatomical and clinical factors likely to interfere with the results of surgery, particularly radical surgery. The mean survival after palliative operations was 5.5 months and after duodenocephalopancreatectomy 16.1 months. After resection, operative mortality as a whole was 21.6%, though in the last 5 years it had fallen to 8.8%. Actuarial survival after 1 yr was 56.3% and after 2 yr 18.8%. The average duration of the symptom picture was long due to the difficulty of making an early diagnosis. This has an adverse influence on the operability of cancer of the pancreas. On average, survival after resection was less in cases with infiltration of the lymph nodes, but not in those with extension of the neoplasia to neighbouring organs, such as the duodenum. The results of radical management were much the same as those reported in the literature and are regarded as unsatisfactory, even though better than those achieved with palliative surgery. Their improvement is discussed in the light of the technical features of duodenocephalopancreatectomy. It is felt that extensive lymphadenectomy is required and that this should be planned and performed in accordance with strict anatomical and surgical criteria.

[Traumatic chylothorax. A further indication for total parenteral nutrition].

Successful and rapid resolution of a serious cases of traumatic chylothorax by means of conservative management with TPN is reported. This method is clearly indicated as a mean of making up the calorie and amino acid need when litres of chyle are being lost every day. In addition, by resting the digestive tract it brings about a massive decrease in the production of lymph in the mesenteric district and thus leading to easier and earlier sufficiency of the collateral lymph drainage routes. The rapid decrease in quantity and the change over from chylous to serous chest drainage liquid after TPN are evidence of its soundness. An immediate lymphographic control revealed complete section of the duct. Two months later, collateral diaphragmatic and azygos circulation was observed. It is felt, therefore, that TPN extends the range of conservative management of posttraumatic and postoperative chylothorax.

[Treatment of thyroid neoplasms and proposed therapeutic plan].

Thirty-seven patients with thyroid cancer were treated at 1a Clinica Chirurgica of Parma between 1962 and 1970. Fourty-five per cent of tumors were papillary, 24 per cent follicular, 2 per cent medullary, 9 per cent anaplastic. Surgery combined with ormonal therapy formed the commonest treatment. Eighty-five per cent of the patients with papillary carcinoma 70 per cent with follicular and 33,3 per cent with anaplastic carcinoma survived for 10 years. This present series indicates that total thiroidectomy combined with ormonal therapy influences the survival time, confirms the prognostic value of histology and shows that papillary node metastases do not prejudice survival.
