Percutaneous cannulation of the dorsalis pedis artery. A prospective study.

Strain-gauge plethysmography was used to determine the systolic arterial pressure in the great toe of 38 patients (aged 23-70 yr) undergoing lung surgery. In eight patients (21%) manual compression of the dorsalis pedis artery reduced the arterial pressure in the great toe to less than 40 mm Hg, and cannulation of the artery was not attempted. In 24 of 30 patients with adequate collateral arterial supply, a Teflon cannula (Venflon 1.20) was inserted percutaneously to the dorsalis pedis artery. Median cannulation time was 160 min. Six patients (25%, 95% confidence limits 10-47%) developed thrombosis of the artery and, in one, unsuccessful cannulation caused thrombosis. In two patients, recanalization of the artery occurred between the 2nd and the 8th day after operation. In four patients, examination 3-5 months after cannulation revealed a persisting decrease in the function of the dorsalis pedis artery. This suggests that the dorsalis pedis artery should not normally be selected for cannulation.

Postoperative arterial oxygen tension after peroperative PEEP-ventilation.

Forty otherwise healthy patients (29 women and 11 men), undergoing elective cholecystectomy, were randomly allocated to be ventilated during the operation either with a positive end-expiratory pressure of 1 kPa (10 cmH2O) (PEEP group) or with intermittent positive pressure ventilation without PEEP (control group). During the operation the mean arterial oxygen tension (PaO2) in the PEEP group increased from 14.6 to 16.5 kPa, while no changes occurred in the control group (13.5 and 13.6 kPa). On the first postoperative day, PaO2 decreased by 12% of the preoperative values in the PEEP group; the decrease was 20% in the control group. On the third postoperative day, the PaO2 in the control group was still 9% below the preoperative values, but on the fifth day, both groups had reached their preoperative PaO2 values. In the postoperative period, no statistically significant difference in PaO2 could be demonstrated between the groups. Determinations of the forced vital capacity and forced expiratory volume in the first second showed no difference between the groups pre- or postoperatively. The present study demonstrated no clinically relevant beneficial effect of peroperative PEEP ventilation on the postoperative arterial hypoxaemia after an upper abdominal laparotomy.

Arterial dominance in the hand.

Arterial pressure was measured simultaneously in the thumb and in the contralateral arm using strain-gauge plethysmography in 100 healthy persons aged 13--43 yr, before and after compression of the radial or the ulnar artery. The radial and ulnar pulses were palpable in all instances. In 29 (14.5%) hands compression of either artery did not reduce the thumb pressure. In 152 (76%) occlusion of the radial artery caused a decrease of more than 10 mm Hg, but never to less than 40 mm Hg. In 91 (45.5%) occlusion of the ulnar artery reduced thumb pressure, on three occasions to less than 40 mm Hg. Radial dominance was shown in 110 hands (55.0%), 24 (12.0%) showed ulnar dominance and in 66 (33.0%) neither vessel dominated.

Blood pressure in the great toe with simulated occlusion of the dorsalis pedis artery.

Blood pressure was measured in both great toes using strain-gauge plethysmography in 100 healthy persons aged 18 to 43 before and during successive compression of the dorsalis pedis artery, the posterior tibial artery, and both arteries at the same time. In 54 (27 percent) of 200 feet, successive compression of the dorsalis pedis and the posterior tibial arteries produced no decrease in pressure in the great toe. In 47 of the feet, toe pressure decreased significantly only after compression of the posterior tibial artery, and in 65 of the feet toe pressure decreased significantly only after compression of the dorsalis pedis artery. In 34 of the feet, toe pressure decreased significantly after compression of each of the arteries. Thus in 99 (50 percent) of 200 feet, compression of the dorsalis pedis artery decreased the pressure in the great toe significantly, and in 4 feet the pressure decreased below 40 mm Hg. When both arteries were simultaneously compressed, 69 feet showed detectable blood pressure in the great toe. Attempts to evaluate adequacy of collateral circulation by pressure blanching of the great toe prior to artery compression and then observing capillary refilling time upon release of toe compression proved unreliable.
