Background: Spinal anesthesia is popular, simple and well accepted reliable technique for below umbilicus surgery. It frequently used lower segment section because of its rapid onset, a dense neural block, avoidance risk airway, little local anesthetic toxicity minimal transfer drug to the fetus, as failure block. Objectives this study was compare incidence severity hypotension, dose requiremen...

The standard of treatment of decompensated class IV congestive heart failure (CHF) usually involves positive ionotropic agents such as continuous infusion of dobutamine. When this is inadequate, or the patient is unable to tolerate the dobutamine, secondary to refractory tachycardia/malignant arrhythmia, phosphodiesterase inhibitors, such as Milrinone/Amrinone are commonly employed. The mechani...

Carotid sinus hypersensitivity has a high prevalence in the elderly and is a possible cause of falls. In carotid sinus hypersensitivity, external triggers cause sudden reductions in blood pressure, leading to dizziness or syncope, resulting in falls. Turning of the head is considered an important example of such an external trigger in everyday life, wherein rotation of the neck is thought to ma...

Hypotension is a commonly encountered complication in haemodialysis patients and is a significant cause of morbidity and mortality. Bilateral visual loss in dialysis induced hypotension remains poorly recognized as a complication by both renal physicians and ophthalmologists. We report 2 cases of patients on renal dialysis who suffered severe longstanding hypotension with bilateral non-arteriti...

Several recently reported deaths following the use of sodium nitroprusside have been attributed to the accumulation of the nitroprusside metabolite, cyanide. In this study, brief nitroprusside infusions (mean = 36 minutes) were administered in currently recommended doses during intracranial surgery. The peak blood cyanide following the infusions was 65.2 +/- 17.5 microgram per cent (mean +/- SE...

Background Exercise-induced hypotension in patients with coronary artery disease (CAD) has been considered to be due to an inability to achieve an adequate increase in cardiac output to match the demands of exercise. We investigated 10 consecutive patients (9 men and 1 woman; age, 38 to 71 years; mean, 52 years) with angiographically documented CAD and exercise-induced hypotension (EIH) (BPpeak...
