HUBUNGAN ANTARA PEMBERIAN TERAPI CAIRAN KRISTALOID DENGAN MEAN ARTERIAL PRESSURE PADA PASIEN SPINAL ANESTESI Ni Made Sitha Adelia Maheswari Fakultas Kesehatan Program Studi D IV Keperawatan Anestesiologi Institut Teknologi dan Kesehatan Bali Email: [email protected] ABSTRAK LatarBelakang: Mean Arterial Pressure dapat berubah akibat dari anestesi spinal karena terjadinya vasodilatasi yang disebabkan adanya blockade saraf simpatis. Pemberian cairan kristaloid dengan preloading dan coloading ialah pemberian cairan yang banyak pada waktu yang singkat setelah dilakukannya regional anestesi. Tujuan: Untuk mengidentifikasi hubungan antara pemberian terapi cairan kristaloid dengan Mean Arterial Pressure pada pasien spinal anestesi. Metode: Desain penelitian ini deskriptif korelasi dengan pendekatan cross sectional. Penelitian ini dilakukan di RSU Kertha Usada Buleleng pada bulan April-Mei 2023, sampel pada penelitian ini adalah 113 responden yang menjalani pembedahan menggunakan anestesi spinal yang dipilih dengan teknik purposive sampling. Pengumpulan data menggunakan lembar observasi dan analisa data menggunakan deskriptif statistik uji fisher’s exact. Hasil: Tidak adanya hubungan antara pemberian terapi cairan kristaloid dengan mean arterial pressure pada pasien spinal anestesi. Dengan mean arterial pressure setelah diberikan terapi cairan kristaloid pada kategori normal antara 70-105 mmHg (69,9% ) dan pada nilai hipertensi > 105 mmHg (30,1%.). Kesimpulan: Penelitian ini menemukan bahwa pemberian terapi cairan kristaloid pada menit ke-15 pertama tidak berhubungan dengan Mean Arterial Pressure pada pasien dengan tindakan spinal anestesi, sehingga perlu dilakukannya observasi mean arterial pressure pada menit ke-5 sampai ke-30 setelah pemberian terapi cairan kristaloid pada pasien spinal dilakukan.

THE RELATIONSHIP BETWEEN CRYSTALLOID FLUID THERAPY AND MEAN ARTERIAL PRESSURE ON PATIENTS WITH SPINAL ANESTHESIA Ni Made Sitha Adelia Maheswari Faculty of Health Diploma IV of Nursing Anesthesiology Institute of Technology and Health Bali Email: [email protected] ABSTRACT Background: Mean Arterial Pressure can change as a result of spinal anesthesia due to vasodilatation caused by sympathetic nerve blockade. The crystalloid fluid therapy with preloading and co-loading is the administration of large amount of fluid in a short time after regional anesthesia is performed. Purpose: To determine the relationship between crystalloid fluid therapy and Mean Arterial Pressure on patients with spinal anesthesia. Method: This study employed descriptive correlation design with cross sectional approach. The research was conducted in Kertha Usada Hospital in April-May 2023. There were 113 respondents who have undergone incision with spinal anesthesia and those were chosen by using purposive sampling technique. The data were collected by using observation sheet and the data were analysed by using descriptive statistic fisher’s exact test. Findings: There was not relationship between crystalloid fluid therapy and mean arterial pressure on patients with spinal anesthesia. By mean arterial pressure after being given crystalloid fluid therapy, the blood pressure was 70-105 mmHg (69.9%) and hypertension was > 105 mmHg (30,1%.). Conclusion: The crystalloid fluid therapy which is given during 15th minute doesn’t correlate with Mean Arterial Pressure on patients with spinal anesthesia. Thus, the observation is needed during 5th minute until 30th minute after being given crystalloid therapy. Keywords: Crystalloid, Mean Arterial Pressure, Spinal Anesthesia
