The purpose of the study was to evaluate the efficiency of postoperative analgesia with tramal in the newborns. Analgesia with tramal (5% solution for injections, "Gruonental GmbH", Germany) was administered postoperatively in 20 newborn children. Thirteen children were operated for congenital malformations in the gastrointestinal and urinary tracts, three children were operated for purulent-septic diseases and four children were operated for neoplasms. Hemodynamics indices, i.e. heart rate (HR) and arterial pressure, as well as SaO2, respiratory rate (RR), acid-base condition and behavioral reactions were assessed. Analgesia was implemented by the method of continuous intravenous infusion of tramal, 0.1-0.2 mg/kg.h combined with boluses, 1-2 mg/kg. The newborns were asleep for a major part of time during analgesia with tamal; the stable indices of hemodynamics, acid-base balance, glycemia and of the cortisol level were registered. Arterial hypertension, caused by several factors including the effect produced by tamal, was noted in 70% of children. Dose-dependent hypercapnia was registered in 80% of tests in children at unassisted respiration during the infusion of tamal, which is indicative of that tamal affects the respiratory center during the neonatal period and that it is necessary to monitor thoroughly the respiratory functions, i.e. RR, SatO2, pO2, pCO2, and to choose accurately a preparation dose. The continuous infusion of tamal ensures a sufficient analgesia after different operations and especially after medium-traumatic operations. |
