Hubungan Posisi Pembedahan Intra Operasi Dengan Kejadian Hipotensi Pada Pasien Spinal Anestesi Di RSUD Klungkung Ni Made Sri Dwipayani Fakultas Kesehatan Program Studi D IV Keperawatan Anestesiologi Institut Teknologi dan Kesehatan Bali Email: [email protected] ABSTRAK Latar Belakang: Hipotensi pada anestesi spinal sangat dipengaruhi oleh posisi pasien. Posisi pembedahan merupakan praktik menempatkan pasien pada posisi fisik tertentu selama pembedahan. Perubahan posisi tubuh dapat mempengaruhi perubahan hemodinamik non invasif diantaranya tekanan darah, denyut jantung, saturasi oksigen, dan frekuensi pernafasan. Tujuan: Untuk mengetahui hubungan posisi pembedahan intra operasi dengan kejadian hipotensi pada pasien spinal anestesi di RSUD Klungkung. Metode: Penelitian ini menggunakan desain analitik korelasi dengan pendekatan cross sectional. Besar sampel dalam penelitian ini 144 responden. Alat pengumpulan data yang digunakan berupa lembar observasi. Cara pengambilan sampel dalam penelitian ini adalah non probability sampling dengan teknik consecutive sampling dan analisis menggunakan uji Chi-square test. Hasil: Hasil penelitian yang dilakukan menunjukkan bahwa dari 144 responden yang telah menjalani operasi elektif spinal anestesi di RSUD Klungkung sebanyak 67 responden (46,5%) mengalami kejadian hipotensi sedangkan yang tidak terjadi hipotensi sebanyak 77 responden (53,5%). Berdasarkan uji Chi-square test di dapatkan p value 0,05 (p value ≤ 0,05) atau didapatkan nilai χ2 hitung sebesar 5,981 > χ2 tabel sebesar 5,591 yang artinya Ha diterima dan Ho ditolak. Kesimpulan: Dalam penelitian ini terdapat hubungan yang signifikan antara posisi pembedahan intra operasi dengan kejadian hipotensi pada pasien spinal anestesi. Kata Kunci: Posisi Pembedahan, Hipotensi, Spinal Anestesi

The Correlation Between the Position of Intraoperative Surgery and the Incidence of Hypotension in Patients with Spinal Anesthesia at Klungkung Hospital Ni Made Sri Dwipayani Faculty of Health Diploma IV Nursing Anesthesiology Institute of Technology and Health Bali Email: [email protected] ABSTRACT Background: Hypotension in a spinal anesthetia is strongly influenced by the position of the patient himself. Surgical positioning is locating the patient in a certain physical position during the surgical process. Changes in body position could affect non-invasive hemodynamic changes namely blood pressure, heart rate, oxygen saturation, and respiratory rate. Purpose: To determine the correlation between the position of intraoperative surgery and the incidence of hypotension in patients with spinal anesthesia at Klungkung Hospital. Method: This study employed analytic correlation design with cross sectional approach. There were 144 respondents recruited as sample of the study which were selected by using non probability sampling with consecutive sampling technique. The data were collected by using observation sheet and analyzed by using Chi-square test. Result: The finding showed that there were 67 respondents (46.5%) experienced hypotension and there were 77 respondents (53.5%) did not experience hypotension. Based on the Chi-square test, p value of 0.05 was obtained (p value ≤ 0.05) or a calculated χ2 value of 5.981 > χ2 table of 5.591, which meant Ha was accepted and Ho was rejected. Conclusion: There is a correlation between the position of intraoperative surgery and the incidence of hypotension in patients with spinal anesthesia.
