Hemodialysis with bicarbonate 30 mEq/l versus 34 mEq/l and acetate: better hemo...
Bruges, M; Serviço de Nefrologia, Hospital de Santa Cruz, Carnaxide.; Barata, J D; Oliveira, C; Furstenau, C; Gomes, E M; Simões, JThe use of bicarbonate buffer in dialysis is more physiological than acetate. The aim of this prospective study was to compare the hemodynamic stability, acid-base and electrolyte balance changes in a group of 5 hospital hemodialysis (HD) patients, with 3 different dialysis fluids: one with 30 mEq/l of bicarbonate (B30), another with 34 mEq/l of bicarbonate (B34) and the last with acetate (ACE). All the patient...

Barata, J D; Serviço de Nefrologia, Hospital Santa Cruz, Carnaxide, Sanofi Portugal.; Oliveira, C; Bruges, M; Gusmão, L; Santana, A; Ponce, P; Simões, JTo test the efficacy and safety of a low molecular. Weight heparin (LMWH)--Fraxiparine, for hemodialysis (HD) anticoagulation, compared with conventional heparin (H) or serum lavage without other anticoagulation (L).Prospective controlled study.Twenty-nine consecutive patients referred for dialysis in a tertiary care hospital were divided in 3 groups A, B and C, each group A and B patient submitted to 2 dialysi...
Identification of a period of renal ischemic vulnerability studying the changes...
Barata, J D; Serviço de Nefrologia, Hospital de Santa Cruz, Carnaxide.; Bruges, M; Oliveira, C; Simões, J; Bruges, L; Melo, J Q; Melo-Gomes, RWe studied the pre operative status and the 1st, 4th, 12th and 24th hours of the post operative period after open heart surgery with cardiopulmonary bypass with a crystalloid solution containing 10 gr of mannitol. We considered acute renal failure (ARF) as being any increase in plasma creatinine values of 0.25 mg/dl for the first 24 hours and 0.5 mg/dl for periods longer than 24 hours. Six patients had transito...
Hydro-electrolyte changes induced by transurethral prostatic resection.
Ponce, P; Correia, R; Guimarães, P; Freitas, M; Barata, J D; Santos, J RTransurethral resection prostatectomy (TURP) has been associated with severe hyponatremia due to massive absorption of bladder irrigation fluid (IF). TURP was performed in 41 patients using Sorbitol-Mannitol IF (Group A) and in 6 patients using distilled water (Group B). Six other patients were operated upon using surgical procedures identical in time and type of anesthesia to TURP (Group C). The three groups w...
