↵* Remifentanil–furosemide: a white precipitate appeared in the 1:1 (with or without agitation), 1:4 and 4:1 solutions after 15, 30 and 120 min, respectively.
↵† Remifentanil–MgSO4/GS–furosemide: a white precipitate appeared in all solutions, after 15 min (1:1:1 and 4:1:4), 60 min (4:1:1), 24 h (1:1:4, 4:4:1) or more (1:4:1, 1:4:4).
↵‡ Remifentanil–KCl–furosemide: a white precipitate appeared in the 4:1:4, 1:1:1, 4:1:1 and 4:4:1 solutions after 15, 60, 120 min and 24 h respectively. The other solutions remained clear.
↵§ Remifentanil–KCl–MgSO4/GS–furosemide: a white precipitate appeared after 15 min (4:4:1:1, 4:1:1:4 solutions), 30 min (1:1:1:1, 4:1:1:1, 4:1:4:4, 4:4:1:4 solutions) and 24 h (4:1:4:1 solution). The other solutions remained clear, but the 1:1:4:4, 1:4:4:1 and 4:4:4:1 solutions showed a lot of little bubbles.
C, compatible; D5W, dextrose 5%; GS, Glucosaline (3.3% dextrose and 0.3% NaCl); IC, incompatible; NS, NaCl 0.9%; RLS, Ringer lactate stocker.
