HUBUNGAN KETINGGIAN BLOK SPINAL ANESTESI DENGAN KEJADIAN HIPOTENSI INTRA OPERATIF DI RUANG INSTALASI BEDAH SENTRAL RUMAH SAKIT TINGKAT II UDAYANA DENPASAR Ahmad Faisal Nurhakiky Fakultas Kesehatan Program Studi D-IV Keperawatan Anestesiologi Institut Teknologi Dan Kesehatan Bali Email : [email protected] ABSTRAK Latar Belakang : Dari data studi pendahuluan tiga bulan terakhir, jumlah pasien yang dilakukan spinal anestesi di RS TK II Udayana adalah sebanyak 235 pasien 50-60% pasien yang dilakukan operasi regional anestesi dengan teknik spinal anestesi ternyata mengalami hipotensi pada intra operatif. Kejadian hipotensi setelah diberikan obat anestesi spinal disebabkan oleh beberapa faktor salah satunya yaitu ketinggian blok, sehingga perlu dilakukan penelitian tentang hubungan ketinggian blok spinal anestesi dengan kejadian hipotensi. Tujuan : Untuk mengetahui Hubungan Ketinggian Blok Dengan Kejadian Hipotensi di Ruang Instalasi Bedah Sentral Rumah Sakit Tingkat II Udayana Denpasar. Metode : Jenis penelitian yang digunakan dalam penelitian ini adalah analitik korelasional dengan metode pendekatan cross sectional, pengambilan sampel menggunakan teknik sampling yaitu convenience sampling dengan jumlah 75 responden pasien dengan tindakan anestesi spinal, instrument yang digunakan pada penelitian ini adalah lembar observasi dan penelitian ini dianalisis menggunakan uji statistik rank spearmen (Rho). Hasil : Hasil penelitian menunjukkan ketinggian blok rendah yang terjadi hipotensi sebanyak 1 (1,3%), pada ketinggian blok sedang yang terjadi hipotensi sebanyak 69 (92,1%), serta pada ketinggian blok tinggi yang terjadi hipotensi sebanyak 1 (1,3%). Terdapat pengaruh signifikan antara ketinggian blok dengan kejadian hipotensi yang berarti tingkat hubungan korelasi lemah dengan nilai rho -0,493 dengan arah korelasi negatif yang artinya semakin rendah ketinggian blok maka semakin tinggi resiko tidak terjadinya hipotensi. Kesimpulan : Terdapat hubungan signifikan antara Ketinggian Blok Dengan Kejadian Hipotensi Intra Operatif di ruang Instalasi Bedah Sentral Rumah Sakit Tingkat II Udayana Denpasar. Kata Kunci : Ketinggian Blok, Kejadian Hipotensi, Anestesi Spinal.

THE CORRELATION BETWEEN BLOCK HEIGHT OF SPINAL ANESTHESIA WITH INTRAOPERATIVE HYPOTENSION INCIDENT IN CENTRAL SURGICAL INSTALLATION OF UDAYANA HOSPITAL Ahmad Faisal Nurhakiky Faculty of Health Diploma IV Nursing Anesthesiology Institute of Technology and Health Bali Email : [email protected] ABSTRACT Background: Based on the preliminary study data for the last three months, the number of patients who underwent spinal anesthesia at Udayana Hospital was 235 patients. 50-60% of patients who underwent regional anesthesia with spinal anesthesia experienced intraoperatively hypotensive. The incidence of hypotension after being given spinal anesthetia is caused by several factors, one of them is the height of the block, so it is necessary to do research on the correlation between the height of the spinal anesthesia block and the incidence of hypotension. Purpose: To determine the correlation between block height of spinal anesthesia with intraoperative hypotension incident in central surgical installation of Udayana Hospital. Method: This study employed analytic correlation study with cross sectional approach. There were 75 respondents recruited as sample of the study which were selected by using convenience sampling technique. The data were collected by using observation sheet and analyzed statistically by using rank spearmen (Rho) test. Result: The finding showed that 1 respondent (1.3%) had low block height and experienced hypotension, there were 69 respondents (92.1%) had moderate block height and experienced hypotension and at a high block height there was hypotension as much as 1 (1.3%). There was a significant effect between block height and the incidence of hypotension, which meant the level of correlation was weak with a rho value of -0.493 with a negative correlation direction, which meant that the lower the block height, the higher the risk of not developing hypotension. Conclusion: There is a significant correlation between block height of spinal anesthesia with intraoperative hypotension incident in central surgical installation of Udayana Hospital.
