PREVALENSI HIPOTENSI INTRA OPERASI PADA PASIEN BEDAH ORTOPEDI DENGAN SPINAL ANESTESI DI RUANG OK RSU KERTHA USADA SINGARAJA Ni Komang Dewi Kristina Fakultas Kesehatan Program Studi D IV Keperawatan Anestesiologi Institut Teknologi Dan Kesehatan Bali Email : [email protected] ABSTRAK Latar belakang : 56,3% dari 80 orang masih mengalami hipotensi dengan penggunaan spinal anestesi, pada intra operasi dapat menyebabkan terjadinya hipoperfusi organ-organ vital yang mengakibatkan terjadi hipoksemia dan kerusakan jaringan sehingga berpotensi menyebabkan komplikasi intra operasi. Tujuan : Mengetahui gambaran hipotensi intra operasi pasien bedah ortopedi dengan spinal anestesi di RSU Kertha Usada Singaraja. Metode : Menggunakan metode kuntitatif dengan desain deskriptif observasional dan pendekatan time series. Sampel yang didapatkan 51 responden dengan consecutive sampling pada bulan Februari-April dan observasi menggunakan tensimeter serta lembar observasi. Data dipresentasikan dalam bentuk frekuensi dan presentase dengan analisa univariat. Hasil : Sebanyak 27,5% responden mengalami hipotensi intra operasi, dengan 9,8% responden mengalami hipotensi di awal pembedahan dan 15,7% responden mengalami hipotensi di akhir pembedahan dengan faktor yang mempengaruhi yaitu umur, IMT, cairan prehidrasi, posisi pasien, durasi operasi dan penggunaan vasopressor. Kesimpulan : Penata anestesi diharapkan dapat memperhatikan kembali faktor-faktor yang menyebabkan hipotensi intra operasi terutama penggunaan cairan prehidrasi, posisi pasien setelah induksi spinal anestesi dan melakukan monitoring intra operasi dengan lebih ketat.

THE PREVALENCE OF INTRA-OPERATIONAL HYPOTENSION IN ORTHOPEDIC SURGICAL PATIENTS WITH SPINAL ANESTHESIA IN THE OPERATING ROOM AT KERTHA USADA GENERAL HOSPITAL, SINGARAJA Ni Komang Dewi Kristina Diploma IV of Nursing Anesthesiology Faculty of Health Institute of Technology and Health Bali Email: [email protected] ABSTRACT Background: 56.3% of 80 people are hypotensive with the use of spinal anesthesia. Intraoperatively it can cause hypoperfusion of vital organs resulting in hypoxemia and tissue damage so it has the potential to cause intraoperative complications. Aim: To find out the intraoperative hypotension in orthopedic surgery patients with spinal anesthesia at Kertha Usada General Hospital, Singaraja. Method: This study employed a quantitative method with a descriptive observational design and time-series approach. The sample of this study was 51 respondents, selected through consecutive sampling during February-April. Data were collected through observations using a sphygmomanometer and observation sheet. Data were analyzed using univariate analysis and presented in the form of frequency and percentage. Results: 27.5% of respondents experienced intraoperative hypotension, with 9.8% of respondents experiencing hypotension at the beginning of surgery and 15.7% of respondents experiencing hypotension at the end of surgery. The influencing factors were age, BMI, fluid pre-hydration, patient’s position, duration of surgery, and the use of vasopressors. Conclusion: Nurse Anesthetists are expected to pay attention to the factors that cause intraoperative hypotension, particularly the use of pre-hydration fluids, the patient’s position after spinal anesthesia induction and perform strict intraoperative monitoring.
