摘要

It is ironic that when the first CFM56 fired into life in 1974, barely anyone outside of General Electric or its French partner Snecma noticed or even seemed to care. It was a low-key debut for an engine that would become an industry game-changer, yet 39 years later the contrast could not be greater for the first run of its 21st-century successor, the all-new Leap. The reason is simple. Compared to the first CFM56, which at the time was an unproven orphan with no applications or orders, the Leap is already a pivotal component of the plans of Airbus, Boeing and Comae. Remarkably, more than 5,000 Leap engines were on order before a drop of fuel was ignited.

7. Chemotherapy is one of the therapies for cancer patients that cause some side effects, one of them is nausea and vomiting. Nausea and vomiting are still felt by patients even though they take antiemetics. Nausea dan vomiting can cause fluid and electrolyte imbalance. The aim of this study was to analysis the effect of combination acupressure wristband and antiemetic among chemotherapy induced nausea vomiting (CINV) on breast cancer patients. This research used quasi experimental research method, with a pre-post test with the control group. The sampling techniques was consecutive sampling with 25 respondents both in intervention group and control group. In the intervention group had received an acupressure wristband. CINV measured on the second day until fourth day after chemotherapy. Nausea and vomiting score were measured twice a day by a telemonitoring methode by Rhodes Index Nausea, Vomiting and Retching (INVR) questionaire. Data were analyzed by paired t-test, independent t-test, Wilcoxon test and Mann Whitney. The result of this study showed that acupressure wristband significantly reduce the chemotherapy induced nausea and vomit (p value = 0.000). The use of acupressure wristband combined with antiemetic therapy can significantly decrease chemotherapy induced nausea and vomiting in breast cancer patients. Acupressure wristband recommended for consideration nursing intervention in treating breast cancer patients who experience nausea and vomiting. [O] . Endah Fatma 2018
