The aim of this research was to investigate fluid distribution abnormalities in extremely obese individuals, and to evaluate changes after weight loss induced by gastric bypass surgery. Fifteen extremely obese
Arterial waveform analysis.The first method to be discussed involves taking advantage of heart-lung interactions, specifically the respiratory variations in arterial pressure that are seen in ventilated patients. These variations have been shown to be related to central blood volume, diastolic function, ...
The concept of fluid balance is at the heart of describing fluid accumulation in any population. Fluid balance is a measure of the intake and output for a given duration. This is classically expressed over a period of time as daily fluid balance (24-h) or cumulative fluid balance (since ad...
Fluid leakage is seen most often with dwell volumes that are too large, especially in the period immediately after catheter placement.25Lower fill volumes should be used. Fluid leakage into thethoraxcan compromise respiration. External fluid leakage around the catheter increases the risk of infection...
Fluid therapy during major surgery: achieving a balance in unknown quantities 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 thes...
9、Doctors say the fluid and scar tissue are an uncommon complication resulting from the quadruple bypass surgery Mr. Clinton had just six months ago.(医生说,肺部积水和疤痕是克林顿六个月前作心脏搭桥手术所引起的并发症,在类似手术中并不常见。) ...
Although septal myectomy is the preferred treatment for medication-refractory hypertrophic obstructive cardiomyopathy (HOCM), the procedure remains subjective. A preoperative planning procedure is proposed using computational fluid dynamics simulations a
Instead, coronary bypass surgery may be required. Bypass surgery is an open-chest or open-heart procedure, and typically involves grafting a piece of healthy blood vessel onto the coronary artery so as to bypass the blockage and restore blood flow to the coronary tissue. The healthy blood ...
