ABSTRACT
Objective: To determine the presence of hyperchloremic acidosis associated with the use of crystalloid solutions in patients with trauma who entered the Intensive Care Unit of Hospital General Xoco.Background: To restore the circulation in patients with trauma is intended to ensure adequate tissue perfusion and avoid excessive accumulation of fluid in the interstitium. Today, the correction of hypovolemia is based on the use of crystalloids and/or colloids. Saline solution is preferred because it is isotonic and cheap, but to infuse large volumes of this, there are changes to the acid-base balance. This is a retrospective study to determine the presence of hyperchloremic acidosis associated with the use of crystalloid solutions in patients with trauma admitted to the Intensive Care Unit (ICU) of Hospital General Xoco.
Material and methods: We reviewed the files of patients admitted for trauma during the period December 26, 2008 to June 25, 2009. Was recorded, age, sex, type of illness, trauma or medical; probability of death through the scale of ISS and APACHE II, cause of discharge, and hours in the Emergency Room or operating room prior to admission to ICU, days in ICU stay, cost of care in ICU for days, estimated by SiGenera project. Were the characteristics and quantity of solution administered prior to admission to the ICU. In all cases, reporting record arterial blood gases, serum electrolytes, lactate reported during the first 6 hours of stay in ICU. Calculate the AG = Na - Cl - HCO3 is why I believe the error or predictive value for metabolic acidosis: pH↓ Cl = (Na - (Cl - HCO3) / Lactate / EB.
Results: Administration of crystalloids resulted in significantly decreased pH 7.30 ± 0.11, and HCO3-16.48 ± 4.82, lactate 3.47 ± 0.87, and Cl-increased to 109.21 ± 4.45. The AG was found in 11.4 ± 3.57 and the ratio of error to predict the degree acidosis in hyperchloremia by 0.4057 ± 0.19 (p › 0.01). The length of stay in ICU was 6.42 ± 4.85 days, days with a cost/patient of 51, 625.76.
Conclusions: The infusion of large volumes of crystalloids acidosis hyperchloremic occurs with normal AG, there is a direct impact of this phenomenon in the days of hospital stay and costs day/patient.
