Randomized Controlled Trial Comparative Study Clinical Trial Retracted PublicationInfluence of nimodipine and nifedipine on intrapulmonary shunting--a comparison to other vasoactive drugs.
This study was assigned to investigate the influence of calcium channel blockers (nimodipine and nifedipine) in comparison to other vasoactive drugs (nitroglycerin, dopamine) on pulmonary shunting (Qs/Qt). Fifty anesthetised patients scheduled for aortocoronary bypass operation were randomly allocated to 5 groups receiving one of the following drugs: nimodipine 1.0 microgram X kg-1 X min-1; nifedipine 0.7 microgram X kg-1 X min-1; nitroglycerin (TNG) 0.5 microgram X kg-1 X min-1; dopamine; micrograms X kg-1 X min-1; placebo (0.9% NaCl). ⋯ In contrast, the increase in cardiac output induced by dopamine (+27%) was accompanied by a significant increase in shunting (+34%). TNG application did not alter Qs/Qt, but pulmonary artery pressure (PAP) decreased markedly (-19%).

Surgical Steps And Lessons Learned In Final Separation Of Three-Years-Old Craniopagus Twins.
The only published paper1 describing the separation of the conjoined twins did not describe the novel steps and techniques of the microsurgery part, which lasted 26 hours. That paper did not include the neurosurgical video, either. The massive intracerebral hemorrhage that occurred on postoperative day 33 was not reported, and its potential causes have not been scrutinized. ⋯ It is impossible to say with certainty the cause of the hemorrhage, since there may have been other unknown causes (e.g., blood pressure spike). As a contributing factor, congestion of the veins is also possible.3 We concluded that closer monitoring, a stricter management of the interdisciplinary team work, and realizing the seriousness of the lack of sufficient structural support earlier could have prevented this unfortunate complication. In a similar case we advise future professionals to use a halo ring postoperatively for posterior protection until a sufficient cranioplasty can safely be done.
