Perbandingan Pemberian Deksametason 10 mg dengan 15 mg Intravena sebagai Adjuvan Analgetik terhadap Skala Nyeri Pascabedah pada Pasien yang Dilakukan Radikal Mastektomi Termodifikasi
Abstract
Deksametason merupakan kortikosteroid yang memiliki efek anti-inflamasi paling kuat. Penelitian ini bertujuan membandingkan deksametason 10 mg dengan deksametason 15 mg intravena prabedah terhadap nyeri pascabedah dan kebutuhan analgetik opioid. Penelitian ini merupakan uji acak terkontrol buta ganda pada 60 wanita dengan status fisik American Society of Anesthesiologist (ASA) I–II yang menjalani pembedahan radikal mastektomi termodifikasi dalam anestesi umum di Rumah Sakit Dr. Hasan Sadikin Bandung periode Desember 2013–April 2014. Pasien dibagi menjadi dua kelompok, yaitu 30 orang menerima deksametason 10 mg dan 30 orang menerima deksametason 15 mg yang diberikan 30 menit prabedah. Penilaian skala nyeri menggunakan nilai numeric rating scale (NRS) pada saat istirahat dan mobilisasi, pada jam ke-1, 2, 4, 12, dan 24 pascabedah. Pemberian analgetik tambahan opioid dilakukan bila nilai NRS>3. Analisis statistika data hasil penelitian menggunakan uji-t, chi-kuadrat, dan Mann-Whitney. Hasil penelitian menunjukan nilai NRS saat istirahat pada kelompok deksametason 10 mg dengan deksametason 15 mg tidak berbeda bermakna (p>0,05), sementara nilai NRS saat mobilisasi pada kelompok deksametason 10 mg lebih tinggi dibanding dengan kelompok deksametason 15 mg (p<0,05). Pemberian analgetik tambahan pascabedah tidak terdapat perbedaan secara bermakna antara kedua kelompok (p>0,05). Simpulan penelitian ini adalah pemberian deksametason 15 mg dapat diberikan karena mempunyai efek analgesia yang lebih baik.

Comparison between 10 mg and 15 mg of Intravenous Dexamethasone as Analgesia Adjunct on Post Operative Pain in Patients Undergo Modified Radical Mastectomy
Dexamethasone is a glucocorticoid with the strongest anti-inflammatory property. The aim of this study was to compare the effect of 10 mg and 15 mg of intravenous dexamethasone on post operative pain and opioid analgetic need. This was a randomized double-blind study involving 60 females with physical status ASA I–II whom underwent modified radical mastectomy under general anesthesia at Dr. Hasan Sadikin General Hospital during December 2013–April 2014. Patients were divided into 2 groups where 30 patients received 10 mg dexamethasone and 30 patients received 15 mg dexamethasone 30 minutes prior to surgery. Pain assessment was performed using numeric rating scare (NRS) at rest and during activity, documented on the 1st, 2nd, 4th, 12th and 24th hour post operative. Additional analgesia was given if NRS >3. Data were analyzed statistically using Student’s t test, chi-square and Mann Whitney U test. Result showed that the difference between NRS at rest for 10 mg and 15 mg dexamethasone (p>0.05) was not significant, while the difference in NRS during activity at all time measurements were statistically significant (p<0.05). There was no statistical significant difference in additional opioid administered between the two groups (p>0.05). This study concludes that 15 mg dexamethasone has a better analgesia effect to reduce analgesic dose.
