Discomfort and Bleeding in Relation to Bedrest Time after Bone Marrow Examination among Hemato-oncology Patients / 임상간호연구

PURPOSE: The purpose of this study was to investigate hemato-oncology patients' discomfort and bleeding in relation to the bedrest time after bone marrow examination. METHODS: A descriptive correlational study was conducted. The data were collected using self-report questionnaire from total of 131 patients who underwent bone marrow examination from January 2017 to September 2017. Data were analyzed with descriptive statistics, Wilcoxon Signed-rank test, McNemar's test and logistic regression. RESULTS: The level of discomfort after 4 hours of bedrest was significantly higher when compared to 2 hours of bedrest(p<.001). The occurrence of bleeding after 2 hours of bedrest was significantly higher than 4 hours of bedrest(p<.001), however the degree of bleeding was slight. No bleeding occurred in 84% of the patients after 2 hours of bedrest. CONCLUSION: The results of this study demonstrated that shortening the bed rest time after bone marrow examination was helpful in improving the patient's well-being. Bedrest time could be shortened according to the site of bone marrow examination and patient's condition.

Comparison of Foot Structure, Function, Plantar Pressure and Balance Ability According to the Body Mass Index of Young Adults

OBJECTIVES: This study compared foot arch height, plantar fascia thickness, a range of motion assessments of the ankle joint, strength of the ankle joint, plantar pressure, and balance between obese and normal weight young adults. METHODS: Fifty-two participants were required for the present study design to achieve 80% power, 0.8 effect size (η2), and an alpha level of 0.05. The participants were categorized to normal weight or obese groups based on BMI (≤ 24 kg/m2 and ≥ 25 kg/m2, respectively). The foot and ankle disability index and Sport survey were completed by the participants before the measurements. Foot arch height was measured using the navicular drop test, and plantar fascia thickness was measured using ultrasound. Plantar pressure and balance tests were also conducted, followed by ankle joint range of motion and strength tests. RESULTS: Foot arch height and plantar fascia thickness was significantly higher in the obese group compared with the normal weight group (p < 0.01). There were significant differences in eversion of ankle strength, plantar pressure in the big toe and heel and anterior-posterior balance between normal and obese weight groups (p < 0.05). CONCLUSION: Obese young adults had more abnormalities in the medial longitudinal arch, plantar fascia, and plantar pressure as well as weakened ankle eversion strength and balance problems compared with the normal weight group.

Estimation of the effect-site equilibration rate constant using the time-to-peak effect of muscle relaxants measured by train-of-four stimulation during general anesthesia induction / 대한마취과학회지

BACKGROUND: The concept of the effect-site concentration of anesthetic agents is important. The effect compartment model can be explained using the concepts of effect-site concentration and effect-site equilibration rate constant (k e0). This study confirms that the time-to-peak effect (tpe ) can be measured easily in clinical practice by applying a priming dose and train-of-four (TOF) during general anesthesia induction, and k e0 can be calculated from the tpe of the four muscle relaxants that are commonly used in general anesthesia. METHODS: Eighty patients who received general anesthesia were divided into the succinylcholine, rocuronium, atracurium, or vecuronium groups. Priming doses of muscle relaxants were administered. The effects of muscle relaxants were quantified by recording the twitch response of the adductor pollicis muscle after stimulating the ulnar nerve. The tpe was measured at the lowest TOF value. k e0 was calculated from the measured tpe . RESULTS: The k e0 values of the succinylcholine, rocuronium, atracurium, and vecuronium groups were 0.076 (0.030)/min, 0.228 (0.122)/min, 0.062 (0.011)/min, and 0.077 (0.019)/min, respectively. CONCLUSIONS: It is possible to estimate k e0 from the tpe of muscle relaxants using a priming dose and TOF during general anesthesia induction.

Metachronous Primary Carcinoid Tumor and Spindle Cell Carcinoma of the Lung

Spindle cell carcinoma (SpCC) of the lung is extremely rare, with an incidence of less than 0.5% among all lung malignancies. Neuroendocrine tumors are frequently associated with secondary primary malignancies. Here, we report a case of metachronous SpCC that occurred after treatment of a primary carcinoid tumor of the lung. The SpCC mass was successfully removed by lobectomy. In immunohistochemical analyses, the tissues were positive for cytokeratin 7 and vimentin.
