Postoperative fluid retention after heart surgery is accompanied by a strongly positive sodium balance and a negative potassium balance[J]. Physiol Rep, 2016, 4(10) : e12807.Hessels L, Oude Lansink A, Renes MH, van der Horst IC, Hoekstra M, Touw DJ, et al. Postoperative fluid ...
The transmural pressure (RAPTM) for the right atrium can be calculated by the formula: RAPTM= RAP −PPL[9]. However, in the clinical practice,PPLandPPERare assumed to be equal to intrathoracic pressure (ITP) which is the external pressure around the heart and the lungs. However, it mus...
Major surgery presents a number of significant challenges to the anaesthetist such as producing adequate ventilation, oxygenation, hypnosis, muscle relaxation and pain relief (nociception) both during and after surgery. All these require a careful balance of the beneficial and unwanted effects of drugs...
*After some operations, patients are deliberately run “on the dry side”, whilst septic patients or patients in bowel obstruction will need aggressive fluid prescribing. Fluid Compartments Around 2/3rdoftotal body weightis water (‘total body water’). Around 2/3 of this distributes in to the...
A Computer-Aided Controller of Fluid Infusion Rate in Post-Operative Management of Open Heart SurgeryDuring the extra-corporeal circulation in open heart surgery, the circulatory blood is diluted from 45% to 20% of hematocrit by massive crystalloid fluid to get the decreased blood viscosity and.....
Radiation is a very common cancer treatment. About 50% of all cancer patients will receive radiation treatment, which may be delivered before, during, or after surgery and/or chemotherapy. Radiation can be delivered externally -- where X-rays, gamma rays, or other high-energy particles are del...
Abdominal surgery alone can induce a sterile, asymptomatic peritonitis. Nucleated cell counts (mostly neutrophils) can remain high (>30,000 cells/µL) for longer than a week after surgery. Neutrophils are usually nondegenerate, and bacteria are absent. ...

Because of the significant risk of elderly patients undergoing open-heart surgery on cardiopulmonary bypass, which includes death, disabling stroke, respiratory and renal complications, dilatation of the narrowed valve using balloon-catheters was hoped to provide an alternative to surgery. Unfortunately, ...
