[Analgesia and intensive therapy in single-step, combined and complex operations].

300 single-step, combined and complex operations have been performed to patients aged 16 to 82 years in the Institute of Proctology, USSR Ministry of Public Health, over the last 10-year period. Surgery was performed under various types of endotracheal combined analgesia: NLA, NLA in combination with halothane or calypsol. Arterial hypotension (short-term BP decrease by more than 40% baseline) was found in 29 patients (9.6%), no intraoperative lethal outcomes have been observed. The volume of the infusion-transfusion therapy depended on intraoperative blood loss, duration of surgery and the extension of surgical interventions (8.4-12.4 ml/kg.h). An overall mortality rate was 3.6%, which does not exceed the mortality rate observed during conventional operations on the colon.
