To investigate the effect of an interventional upper pad at radial vascular access sites in PCI.
This work describes a protocol for a clinical trial, and 590 patients with ischemic coronary heart disease, whose condition was stable over the previous three months, were enrolled in the controlled trial within one year, all between 25 and 80 years of age. The patients were divided into two groups in terms of whether or not an interventional upper pad was used in PCI. The experiment group (EG) (n=319) received an interventional upper pad, whereas control group (CG) followed traditional post-interventional care (n=225). The main outcome variables were the pain score of wrist metacarpus and swelling value of the forefinger's circumference; Secondary outcome variables included the degree of overall comfort at the puncture limb. All outcome variables were measured at the beginning of the interventional period and again at 6 hours after PCI. Information on sex, age, operator and interventional type was also recorded.
Two sets of data were compared in terms of swelling value of the forefinger's circumference at the interventional limb, pain score of wrist metacarpus, the forefinger peripheral SaO2 fluctuation, comfort state self-evaluation about the interventional limb between bilateral limbs at baseline and after six hours in PCI. Patient's carpometacarpal pain score and swelling around the index finger roots in EG were lower than the CG, and the difference was statistically significant (P<0.05); fluctuation of SaO2 at the index finger endings did not change significantly between two groups of patients, and the difference was not statistically significant (P> 0.05). In EG the percentage of effect management about patients' comfort state self-evaluation is 95.61%; otherwise, in control group it is only 16.89%. And the difference was statistically significant (P<0.05).
If the application of an interventional upper pad proves to be effective, the study will be shown that the application of the interventional upper pad can alleviate swelling and pain of wrist metacarpus and improve the degree of overall comfort after PCI.
