Description
Summary:Objectives: This study determines utility of addition of low dose (0.5mg/kg) ketamineto the traditional sedation outlines in patients undergoing lithotripsy.Methods: Experimental prospective blind controlled study in which 60 patients of bothsexes with scheduled lithotripsy were included. Patients were randomized in two groupscontrol and study; the variables to analyze were opiates requirements, post sedationpain, requirement of analgesic, adverse effects and time of stay in recuperation.Results: the variables were evaluated for both groups. There were significantdifferences for opiates requirement (group study: 135±49.6ug vs 160± 56ug groupcontrol t:-1.74 tc:-1.67 and p:0.04); there was variability in vital signs baseline just forhalf blood pressure (MAP 101 ± 12,5 vs 115 ± 20,7 p: 0,00). There was not significantvariability in HR 83± 14 bpm vs 80±12 bpm, Pso2 97± 3.6% vs 97± 3.9%. Aboutnegative outcomes, we didn’t find significant differences in perioperative arrhythmias(RR: 1.55 IC 0,70-3,50 X2:1,26), breathing depression (RR:1.33 IC: 0.32-5.45 X2:0.16), analgesic necessity (RR:1,0 IC: 0,36 - 2,75 X2: 0,0), nausea (RR:2,0 IC 0,19 -20,89 X2: 0,35) and vomits (RR:3,0 IC:0,33 - 27,23 X2:1,07).Conclusions: Ketamine use diminishes opiates requirement without increasing adverseeffects.RESUMEN:ketamina a dosis bajas (0.5mg/kg) a los esquemas de sedación tradicionales enpacientes sometidos a litotripsia extracorpórea.Métodos: estudio experimental prospectivo ciego controlado, en el cual fueronincluidos 60 pacientes de ambos sexos programados para la realización de litotripsiaextracorpórea aleatorizandolos en dos grupos control y estudio, las variables a analizarrequerimientos de opiodes, dolor postsedacion, requerimientos de analgésicos, efectosadversos y tiempo de estancia en recuperación.Resultados: fueron evaluadas las variables para ambos grupos encontrándose diferenciasignificativa en cuanto a requerimiento de opiodes (grupo estudio: 135±49.6ug vs160± 56ug grupo control t:-1.74 tc:-1.67 y p:0.04 ) se encontró variabilidad en cuantoa los signos vitales teniendo en cuenta la línea de base solo para tensión arterial media(TAM 101 ± 12,5 vs 115 ± 20,7 p: 0,001), FC 83± 14 LPM vs 80±12 LPM, Pso2 97±3.6% vs 97± 3.9 % no se encontró variabilidad significativa, evaluando desenlacesnegativos no hubo significancía en cuanto a arritmias peri operatorias (RR: 1.55 IC0,70-3,50 X2:1,26), depresión respiratoria (RR:1.33 IC: 0.32-5.45 X2: 0.16), necesidadanalgésicos (RR:1,0 IC: 0,36 – 2,75 X2: 0,0) , nauseas (RR:2,0 IC 0,19 – 20,89 X2:0,35) y vómitos ( RR:3,0 IC:0,33 – 27,23 X2:1,07).Conclusión: la utilización de ketamina disminuye los requerimientos de opiodes sinaumento de efectos adversos.
