Goal. Compare the area of the sensor unit with the blockade of the sciatic nerve subgluteal and classic access. Achieved 60 blockades of the sciatic nerve in combination with femoral nerve blockade. In group A (30 patients) the blockade of the sciatic nerve was performed classical access, in group B (30 patients) - subgluteal access with the patient lying on his stomach. All of the blockade of the sciatic nerve were performed with 30 ml of 1% lidocaine (epinephrine 1: 200 000). Sensory block was evaluated in the foot, ankle, lower leg, popliteal fossa and hamstring. Evaluation of the sensory block was performed using prick. In group A complete motor block of the sciatic nerve occurred in all 30 patients. In those same 30 patients (100%) developed a full sensory block (++) in the area of the foot, lower leg, popliteal, posterior thigh. All patients had complete motor block of the sciatic nerve. In group B complete sensory block in the area of the foot, lower leg developed in all patients. In the popliteal fossa a full sensory block (++) did not develop in any patient, a partial unit + occurred in 22 patients (73.3%) and in 50 patients (26.7%) did not develop a sensor unit. In group B the sensor unit in the lower, middle and upper third Femur not developed (-) no patient. When the blockade of the sciatic nerve subgluteal access full sensor unit is not developed in the popliteal fossa and hamstring. When using the classic access sensor unit is developed in the popliteal fossa and hamstring

Material and methods. In group 1 (20 patients) the blockade of the sciatic nerve was performed subgluteal access; in group 2 (20 patients) - subgluteal access to soft tissue compression in the projection of the sciatic nerve for 3-5 cm distal to the injection site; gluteal access is blockade of the sciatic nerve - in the third group (20 patients). All of the blockade of the sciatic nerve was performed by administering 30 mL of 1% lidocaine (epinephrine 1: 200 000). Sensory block was evaluated in the foot, ankle, lower leg, popliteal fossa and hamstring. A total of 60 patients. Also, in addition to the blockade of the sciatic nerve was performed femoral nerve blockade. Results. Complete motor and sensory block of the sciatic nerve occurred in all 60 patients of the 1st, 2nd and 3rd groups. In group 1, a full block back femoral cutaneous nerve and the popliteal fossa region did not develop in any patient. In 19 patients in group 2 developed a full suite of «+» posterior femoral cutaneous nerve. In 1 patient in group 2 block PFCN was assessed as partial «+». In all patients, the third group developed a full suite of «+» PFCN. Conclusion. When the sciatic nerve blockade subgluteal access full sensor unit is not developed in the popliteal fossa and hamstring. When the sciatic nerve blockade gluteal access sensor unit is developing in the area of the foot, lower leg, popliteal fossa and hamstring. Our method wire blockade of the sciatic nerve and PFCN «2-in-1» from subgluteal access can achieve the touch in the foot, lower leg, popliteal fossa and hamstring.

ABSTRACT:A 77-year-old man developed progressive sensory and motor symptoms in the right lower leg. Examination showed neurological deficits in the distribution of the right tibial and common peroneal nerves. Swellings in both popliteal fossae were palpated. Investigation showed these to be large thrombosed aneurysms. On surgical examination on the right, the aneurysm was found to be compressing the distal sciatic nerve.

Spontaneous Delivery

Previous research has revealed that passive (involuntary inhalation) tobacco smoking during gestation can have adverse effects upon the developing fetus. These prior investigations did not concentrate on changes in fetal morphology. This study was undertaken to delineate fetal neural abnormalities at the ultrastructural level in mice pups exposed in utero to passive maternal smoking.Pregnant study animals, housed in a special chamber, were subjected to cigarette smoke daily from conception until delivery. Blood tests for determination of carbon monoxide levels were run at 15-18 days gestation. Sciatic nerve tissue from experimental and control animals were obtained following spontaneous delivery and fixed in 2.5% gluteraldehyde in 0.1M cacodylate buffer pH 7.3. The samples were post-fixed in osmium ferrocyanide (1:1 mixture of 1.5% aqueous OSO4 and 2.5% K4 Fe(CN)6). Following dehydration, the tissues were infiltrated with and embedded in Spurr. Sections were stained with uranyl acetate and lead citrate.

Several speculations exist as to the site of incorporation of preformed molecules into myelin. The possibility that an autoradiographic analysis of cholesterol-1,2-H3 incorporation at very short times after injection might shed some light in the solution of that problem led to the present experiment.Cholesterol-1,2-H3 was injected intraperitoneally into 24 tenday old mice. The animals were then sacrificed at 10,20,30,40,60,90,120 and 180 min after the injection and the sciatic nerves were processed for electron microscope autoradiography. To analyze the grain distribution in the autoradiograms of cross and longitudinal sections from each sciatic nerve myelin sheaths were subdivided into three compartments named: outer 1/3, middle 1/3 and inner 1/3 compartments.It was found that twenty min. after the injection of cholesterol -1.2-H3 (Figs. 1 and 2), 55% of the total number of grains (t.n.g) found in myelin were within the outer 1/3 compartment, 9% were within the middle 1/3 and 36% within the inner 1/3 compartment
