Skin blood flow was monitored using a laser-Doppler (LD) flowmeter in 21 healthy volunteers after an occlusion of the digital arteries. The peripheral vascular bed was exposed to occlusion ischemia of varying duration (1, 4, or 8 min) and to a change in digital arterial pressure produced by different positions of the arm above heart level to characterize the pattern of LD flow oscillations in postocclusive reactive hyperemia (PRH) and to elucidate the relevance of metabolic and myogenic mechanisms in governing its fundamental frequency. The descending part of the hyperemic flow was characterized by the appearance of conspicuous periodic oscillations with a mean fundamental frequency of 7.2 +/- 1.5 cycles/min (SD, n = 9), as assessed by a Fourier transform frequency analysis of 50-s sections of flow. The mean respiratory frequency during the periods of flow frequency analysis was 17.0 +/- 2.2 (SD, n = 9), and the PRH oscillations remained during apnea in all tested subjects. The area under the maximum flow curve increased significantly with prolongation of the occlusion (paired t test, P < 0.001; n = 9), but showed no dependence on the estimated blood pressure in the digital arteries, which suggests the predominant role of a metabolic component in this part of the PRH response. In contrast, the fundamental frequency of PRH oscillations exhibited a significant decrease with a reduction in the estimated digital arterial pressure (linear regression, b = 0.08, P < 0.001; n = 12), but did not change with the prolongation of arterial occlusion despite a significant increase in mean LD flow (paired t test, P < 0.001; n = 9).(ABSTRACT TRUNCATED AT 250 WORDS)

Studi memperkirakan emesis gravidarum terjadi pada 50-90% kehamilan. Mual muntah pada kehamilan memberikan dampak yang signifikan bagi tubuh dimana ibu menjadi lemah, pucat dan cairan tubuh berkurang sehingga darah menjadi kental (hemokonsentrasi). Keadaan ini dapat memperlambat peredaran darah dan berakibat pada kurangnya suplay oksigen serta makanan ke jaringan sehingga dapat membahayakan kesehatan ibu dan janin. Salah satu terapi yang aman dan dapat dilakukan untuk mengurangi keluahan mual muntah pada ibu hamil adalah pemberian aromaterapi lemon. Penelitian bertujuan untuk mengetahui efektifitas aroma terapi lemon untuk menangani emesis gravidarum. Penelitian ini menggunakan rancangan Quasi experiment  dengan  one group pre-post test design. Populasi penelitian adalah ibu hamil yang mengalami emesis gravidarum di Kecamatan Berbah, Sleman. Jumlah sampel 20 ibu hamil trimester pertama yang diambil dengan teknik purposive sampling. Pengukuran mual muntah dilakukan debelum dan setelah  pemberian aromaterapi lemon menggunakan Indeks Rhodes. Analisa data menggunakan uji Paired t-test. Hasil penelitian didapatkan rata-rata skor mual muntah sebelum pemberian aromaterapi lemon berdasarkan Indeks Rhodes pada Ibu Hamil dengan emesis gravidarum yaitu 22,1 dan terjadi penurunan skor setelah pemberian aromaterapi lemon menjadi 19,8. Ada pengaruh pemberian aromaterapi lemon dengan pengurangan mual muntah pada ibu hamil (p-value = 0.017). Berdasarkan hasil penelitian dapat disimpulkan pemberian aromaterapi lemon efektif untuk mengurangi emesis gravidarum pada ibu hamil trimester pertama.  Kata kunci: aromaterapi lemon, emesis gravidarum THE EFFECTIVENESS OF LEMON AROMATHERAPY FOR HANDLING EMESIS GRAVIDARUM   ABSTRACT Studies estimate that nausea and vomiting (emesis gravidarum) occur in 50 – 90% of pregnancies. Nausea and vomiting of pregnancy have a significant impact on the body in which it makes a mother becomes weak, pale, and decreasing body fluid so that the blood becomes thick (hemoconcentration). This situation can slow down blood circulation and inflict the lack of oxygen and food supplies to the body tissues so that it can endanger the health of the mother and fetus. One of the therapies that is safe and can be conducted to reduce nausea and vomiting of pregnancy is by giving the lemon aromatherapy treatment. The research aims to determine the effectiveness of the aroma of lemon therapy to deal with emesis gravidarum. This study applied quasi-experimental research with one group pretest-posttest design. The population of this study was pregnant women who experienced emesis gravidarum. Furthermore, samples were 20 mothers from Berbah, Sleman taken by using a purposive sampling technique. Nausea and vomiting were assessed between before and after giving lemon aromatherapy using the Rhodes Index. The data were analyzed using the paired t-test. The mean score of nausea and vomiting before giving lemon aromatherapy on mother with emesis gravidarum based on the Rhodes Index was 22.1. However, it decreased after given lemon aromatherapy treatment to 19.8. Therefore, there was an effect on giving lemon aromatherapy treatment toward the decrease of nausea and vomiting for pregnant women (p-value = 0.017). Lemon aromatherapy is effective to reduce emesis gravidarum.  Keywords: lemon aromatherapy, emesis gravidarum
