Perbedaan Perubahan Konsentrasi Natrium Plasma antara Preload 20cc/kgbb Ringer Laktat Dibandingkan dengan Preload 20cc/kgbb Ringer Asetat Malat

摘要

Background The use of fluid resuscitation in a large amount is an important factor which influences the balance of fluid and electrolytes in pathological patients. To give a large amount of fluid, the least affecting plasma osmolarity should be choosen and one of its parameter is sodium. Sodium is the biggest electrolyte ion component found in extracellular fluid. Ringer lactate and ringer acetate malate are crystalloid fluid types with different sodium concentrations. Ringer acetate malate has a higher sodium concentration and its osmolarity is closer to plasma osmolarity compared with ringer lactate. Therefore, it is considered more effective in fluid resuscitation.Aim To Analyze the difference of plasma sodium concentration modification between preload 20 cc/kgBody weight of ringer lactate and preload 20 cc/kgBody weight ringer acetate malate.Methodology This study is an experimental study with phase II clinical trial which was conducted randomly single-blind. The sample is 40 patients who underwent elective operations with spinal anesthetic at the Central Surgery Unit of dr.Kariadi Hospital Semarang who fulfilled inclusive and exclusive criteria to be divided into two groups. The choice of sample was made based on consecutive random sampling. The first group was given preload 20cc/kgBody weight ringer lactate and the second group was given preload 20 cc/kgBB ringer acetate malate. Before the giving of the preload, the patients\u27s blood sample was taken for the purpose of plasma sodium concentration examination. Next, after ten to fifteen minutes, another blood sample taking was conducted immediately in order to examine the plasma sodium concentration of electrolytes. Then, the results of the examination were compared with the basic data and were statistically tested. The data were analyzed and processed based on computer software program. The statistic test made used of t-test and p degree of significance=0,05. Finally, The results of the data analysis were presented in the form of tables and graphs.Results The mean value of the sodium before the giving of preload ringer lactate is=137,1±2,8 and after the giving of preload ringer lactate is=138,2±3,3 (p=0,021). The mean value of the sodium before the giving of preload ringer acetate malate is=137,2±1,8 and after the giving of preload ringer acetate malate is= 138,3±2,2 (p=0,013). However the difference is not statistically significant (p=0,880) at the use of preload 20cc /kgBody weight ringer lactate as compared with the use of preload 20 cc/kgBody weight ringer acetate malate.Conclusion There is no significant difference of sodium concentration modification in plasma in the use of preload 20 cc/kgBody weight ringer lactate compared with the use of preload 20 cc/kgBodyweight ringer acetate malate.
