The Relationship of Self-reported Pain Scores with Vital Signs in Ureter Stone Patients

PURPOSE: Some studies indicate that vital signs such as blood pressure, heart rate, respiration rate, body temperature correlate with each other. However, no study has rigorously confirmed the correlations between vital signs due to study limitations. The aim of this study is to determine the relationship of pain to vital sings and to assess its clinical utility in ureter stone patients. METHODS: All 371 patients with ureter stone admitted to the Emergency Department (ED) at Kyung Hee University Hospital from September 1, 2005 to August 31, 2006 were prospectively involved in our study. We recorded vital signs of all patients 3 times every 10 minutes before analgesic injection and determined mean values. We analyzed the data by using the SPSS 13.0 statistics program. RESULTS: The means for systolic and diastolic blood pressure, heart rate and respiration rate were significantly different in pain score (p<0.05), but were not different by body temperature. Correlations of pain grade to vital signs were calculated, and blood pressure, heart rate and respiration rate showed positive correlation with pain grade (p<0.05). In multivariate analysis by general linear analysis, only systolic blood pressure and respiration rate were significantly associated with pain scores (p<0.05). CONCLUSION: In general, we have a tendency to underestimate the importance of the respiration rate relative to blood pressure, heart rate, and body temperature except in special circumstances, such as COPD or asthma exacerbation. Self-reported pain scores of patients correlate with vital signs, especially blood pressure and respiration rate.

Delayed Presentation of Mitral Valve Leaflet Perforation Following Blunt Chest Trauma: A Case Report

Mitral regurgitation originating from mitral valve leaflet perforation secondary to blunt chest trauma is a rare condition. The mechanisms related with valvular injury are rapid acceleration- deceleration movements of the thorax, compression of the heart between the sternum and vertebrae during early systole or late diastole, and abrupt increase of the intrathoracic pressure followed by cardiac rupture. Transesophageal echocardiography (TEE) is a recommended diagnostic tool and is superior to transthoracic echocardiography (TTE) for diagnosing valvular lesions. Valvular injury causing sudden and severe mitral regurgitation will lead to congestive heart failure and death without operative correction. A high index of suspicion with appropriate diagnostic methods will provide a diagnosis and allow the possibility of operative correction. We report the case of a 45-year-old man with delayed presentation of traumatic mitral valve perforation and review previous reports of blunt traumatic mitral valve injury.

Pseudolesions around the Gallbladder Fossa: Comparison of Frequency and Radiological Characteristics in Multiphasic CT, CTAP, and CTHA

PURPOSE: The purpose of this study is to compare the frequency with which pseudole-sions around the gallbladder (GB) fossa are revealed by multiphasic CT, by CT during arterial portography (CTAP), and by CT during hepatic arteriography (CTHA) and to determine their radiological characteristics. MATERIALS AND METHODS:Multiphasic CT, CTAP, and CTHA examinations of 81 patients without pathology of the GB and around the GB fossa were evaluated for pseudolesion around the GB fossa. The definition of pseudolesion was as follows: 1) hyperattenuation during the arterial phase and isoattenuation during the delayed phase of multipha-sic CT, or perfusion defect on CTAP and hyperattenuation on CTHA; 2) no Lipiodol tagging on Lipiodol CT; 3) all findings observed adjacent to the gallbladder fossa; and 4) no interval change on follow-up CTAP and CTHA. We compared the frequency of pseudolesions around the GB fossa, as seen on multiphasic CT, CTAP, and CTHA, and determined their size, location, and shape, as revealed by CTHA. RESULTS: The frequency of pseudolesion was 2.5% (2/81) on multiphasic CT, while on CTAP or CTHA, the frequency was 53.1% (43/81), and 58 pseudolesions were identi-fied. Of 58 pseudolesions, 56 were revealed by CTAP and 57 by CTHA. Forty-nine of 58 pseudolesions were larger and all pseudolesions showed more contrast to parenchyma on CTHA than on CTAP. The location of pseudolesions was segment V(32 of 58), IV (25 of 58), and VI (1 of 58), and their size ranged from 5 to 30 (mean, 17.5)mm. Pseudolesions were wedge-shaped (48 of 58), oval (6 of 58), bandlike (3 of 58), or round (1 of 58). CONCLUSION: CTAP and CTHA frequently revealed pseudolesion around the GB fossa. The radiological characteristics of these modalities help differentiate pseudolesions from true tumoral hepatic lesions.

Double Uncture fo Single Common Femoral Artery for CT Hepatic Arteriography and CT Arterial Portography

PURPOSE: To evaluate the safety and efficacy of double puncture of a single common femoral artery for CThepatic arteriography(CTHA) and CT arterial portography(CTAP) in patients with hepatocellular carcinoma. MATERIAL AND METHODS: Between October and December 1995, 35 patients with hepatocellular carcinoma underwent doublepuncture of a single common femoral artery for combined CTHA and CTAP. Preangiographic laboratory data were asfollows : platelet count from 28,000 to 250,000/mm3 (average, 124,500/mm3) ; prothrombin time from 45.8% to100%(average, 85.3%). In the inguinal area, a pair of 21G puncture needles were used unilaterally for the firsttwo femoral punctures, at a distance of 5-7mm ; a 0.018" guidewire for the insertion of a 4-F sheath in a coaxialmicropuncure introducer set ; and a 0.035" guidewire and 4 F check-flo sheath for the insertion of 4-F catheters.After being moved to the CT room, patients then underwent spiral CTHA and CTAP for further detection ofhepatocellular carcinoma nodules. Transarterial chemoembolization followed, and the punctured site was thencompressed by the usual finger compression method. After initial compression and one day later, we observed thepuncture site for complications such as hematoma formation, thromboembolization or arteriovenous fistula ; ect. RESULTS: Except for the formation of two mild hematomas, no remarkable severe complications were noted. Fifteenpatients who had previously undergone combined spiral CTHA and CTAP using the bilateral femoral puncture method(with a 5-F check-flo sheath) felt more comfortable than when an earlier method was used. CONCLUSION: For combinedCTHA and CTAP, double puncture of a single common femoral artery is safer and more comfortable than the bilateralfemoral puncture method.
