BACKGROUND Radial artery obstruction is the most common complication of coronary angiography performed via transradial access. Patent hemostasis can significantly reduce the risk of radial artery occlusion. Previous studies utilized sophisticated methods to evaluate radial artery patency. Simplified and easily applicable methods for successful patent hemostasis are currently lacking.AIM To determine which method(pulse oximeter vs the traditional radial artery palpation) is better to achieve patent hemostasis.METHODS This prospective, single center study included 299 consecutive patients who underwent coronary angiography or percutaneous coronary intervention between November 2017 and July 2019. Patients less than 18 years old, with a history of radial artery disease, or no palpable artery pulse were excluded from the study. Patients were randomly assigned to two groups. In the first group, radial artery flow was assessed by palpation of the artery during hemostasis(traditional method). In the second group, radial artery patency was estimated with the use of a pulse oximeter. Two different compression devices were used for hemostasis(air chamber and pressure valve). The primary study endpoint was the achievement of successful patent hemostasis.RESULTS The two groups(pulse oximeter vs artery palpation) had no significant differences in age, sex, body mass index, risk factors, or comorbidities except for supraventricular arrhythmias. The percentage of patients with successful patent hemostasis was significantly higher in the pulse oximeter group(82.2% vs 68.1%, P = 0.005). A lower percentage of patients with spasm was recorded in the pulse oximeter group(9.9% vs 19.0%, P = 0.024). The incidence of local complications, edema, bleeding, hematoma, vagotonia, or pain did not differ between the two groups. In the multivariate analysis, the use of a pulse oximeter(OR: 2.35, 95%CI: 1.34-4.13, P = 0.003) and advanced age(OR: 1.04, 95%CI: 1.01-1.07, P = 0.006), were independently associated with an increased probability of successful patent hemostasis. The type of hemostatic device did not affect patent hemostasis(P = 0.450).CONCLUSION Patent hemostasis with the use of pulse oximeter is a simple, efficient, and safe method that is worthy of further investigation. Larger randomized studies are required to consider its clinical implications.  相似文献

The r?le of serotonin (5-HT) in the cerebrovascular bed is the subject of the following review. Cerebral blood vessels are supplied with 5-HT-containing fibres which originate in the raphé nuclei in the brainstem. The activation of this system may result in a constriction of large arteries and a dilatation of arterioles. Intra-arterial administration of 5-HT causes reduction in cerebral blood flow and metabolism provided it bypasses the blood-brain barrier. The findings, marked changes in plasma levels of 5-HT and in cerebral blood flow during a classic migraine attack, are suggestive of an involvement of the 5-HT system.  相似文献

When cancer of the bladder is treated by removal of the malignant organ, there is a high incidence of impotency in males. A retrospective study of 71 adult patients revealed misconceptions, misinformation, and misinterpretation that could have been alleviated by more timely and appropriate counsel. Nurse-enterostomal therapists are identified as potentially valuable sex counselors but their training in this field is limited. A need for patient education is demonstrated and a plea for follow-up attention to sexual concerns in the extended postoperative period is issued.  相似文献
