Displacement of catheters inserted through internal jugular veins with neck flexion and extension. A preliminary study.

Displacement of central venous catheters inserted through internal jugular veins in adult man was estimated on chest x-rays in six patients and measured in six corpses. The downward displacement of the catheter tips with maximum neck flexion varied between 1.0 and 2.0 cm in patients, and between 1.0 and 2.5 cm in corpses. The upward displacement with maximum neck extension varied between 0.5 to 1.0 cm in patients and 0.5 to 1.5 cm in corpses. The total displacement varied between 1.5 to 3.0 cm in patients, and 1.5 to 4.0 cm in corpses. The geater displacement in corpses might be explained by detachment of sternocleidomastoid muscles, and by resection of the sternum and anterior ribs, performed for access to the heart and superior vena cava. There was no apparent correlation between the side and site of the vein puncture, body length, sternocleidomastoid length, distances from the punction sites to suprasternal notch, and values of the displacements of the catheter tips in any group. To avoid rhythm disturbances and perforation of the heart (possible complications of the catheter displacement), the necessity of locating central venous catheter tips 3.0 to 4.0 cm above the superior vena cava-right atrial junction, and firm fixation of the catheter is stressed.

Long duration subarachnoid anaesthesia with continuous epidural block.

UNLABELLED: A method of spinal anaesthesia with Dixidextracaine-70 (a mixture of xylocaine 40.0 mg + percaine, 10.0 mg+ Dextran-70, 60,0 mg+ distiled water ad 2.0 ml) with continuous epidural block has been tested in 150 patients. The advantages of this association are: the possibility of obtaining a high quality conduction anaesthesia, virtually unlimited in time, the ability to extend over several anatomical regions the surgical field, minimal toxicity, the absence of postoperative pulmonary complications, and the economy. Drawbacks are: the need for two vertebral punctures, the longer induction time of anaesthesia and some difficulty in finding the subarachnoid space after catheterisation of the epidural space. The indications of the method include subdiaphragmatic surgery, interventions on more than one anatomical region, surgery in aging patients, patients with full stomach, and those with anaesthetic and surgical risk, as well as socioeconomic factors which may prevent application of a differentiated and safe narcosis. CONTRAINDICATIONS: those of subarachnoid and epidural block. The incidents and accidents are minimal and specific to both techniques. The fear of producing total subarachnoid anaesthesia by injection of the anaesthetic solution in the epidural space after puncture of the subarachnoid space is virtually unfounded.

Subarachnoid block with an anaesthetic mixture containing dextran. Cytologic changes in the cerebrospinal fluid.

The present study included 22 patients who received an anaesthetic subarachnoid injection of 1.0--1.2 ml Dixidextracaine-70 (a mixture of xylocaine 40.0 mg+cinchocaine 10.0 mg+Dextran-70 60.0 mg+distilled water ad 2.0 ml), associated with adrenaline in a final concentration of 1/10000. Before and 24--168 hours after administration of the subarachnoid anaesthesia, 2.0 ml of cerebrospinal fluid was collected for quantitative and qualitative determination of the cellular elements and for physical and bacteriological examinations. No bacteriological contamination or qualitative and quantitative alterations of leucocytes in the cerebrospinal fluid were found after the administration of anaesthetic-dextran mixture. It is concluded that the association of Dextran-70 with xylocaine and percaine, as well as with adrenaline, for lengthening the duration of the subarachnoid anaesthesia has no acute irritative effect upon the central nervous system and its membranes in the course of seven days following its administration.

[Identification of the epidural space by air-fluid reflux (author's transl)].

Detection of the epidural space by Dogliotti's method with a Tuohy needle (inner gauge 1.6mm) is followed by introduction of 3.0-5.0 ml of test solution and rapid injection of 3.0-5.0 ml air with a 5.0ml syringe. After the introduction of the air, the syringe is immediately removed from the needle. Location of the needle tip in the epidural space is marked by air bubbles coated by a thin fluid film, which hang over the hub of the needle and then burst. In some instances a slight wheezing can be heard as the air introduced into the epidural space comes out. The air-fluid reflux is determined by the elasticity of the dura and points always at the location of the tip of the needle in the epidural space. This sign is present in 95 per cent of the cases. The intensity of the air-fluid reflux depends upon the elasticity of the dura, the diameter of the needle and of the syringe and the force by which the plunger is pushed down.
