Hemodynamic instability frequently occurs in critically ill patients. Pathophysiological rationale suggests that hemodynamic monitoring (HM) may identify the presence and causes of hemodynamic instability and therefore may allow targeting therapeutic approaches. However, there is a discrepancy between this pathophysiological rationale to use HM and a paucity of formal evidence (as defined by th...

conclusions we found that 0.3 mcg/kg of sufentanil attenuates cardiovascular responses to double-lumen endobronchial intubation without adverse effects. background sufentanil is a potent opioid analgesic frequently used in clinical anesthesia. double-lumen endobronchial intubation induces profound cardiovascular responses in comparison with ordinary endotracheal intubation because of the larger...

Carotid body tumours are rare benign that originate from neural non-chromaffin cells typically localized near bifurcation of carotid artery. Reported incidence tumor was 1-2 per 100,000. Surgical removal the is most definitive treatment. It has a high perioperative morbidity and mortality We combined general anaesthesia with regional technique for better haemodynamic stability. Basic elements a...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

introduction: prior studies comparing hemodynamic response function (hrf) in the young and elderly adults based on fmri data have reported inconsistent findings for brain vision and motor regions in healthy aging. it is shown that the averaging method employed in all previous works has caused this inconsistency. the averaging is so sensitive to outliers and noise. however, fmri data are obscure...

We present the case of an 86-year-old patient with severe chronic obstructive pulmonary disease undergoing modified radical mastectomy with axillary dissection by thoracic paravertebral block (PVB). Use of thoracic PVB provided hemodynamic and respiratory stability, excellent unilateral anesthesia and high patient satisfaction.

Emergent stent-graft endovascular aneurysm repair in a 69-year-old male patient with ruptured bilateral iliac artery aneurysms is reported. Endoleak prevention and pelvic circulation preservation are the critical issues in endovascular repair for iliac artery aneurysms, especially when covering bilateral internal iliac arteries. Perioperative hemodynamic stability is crucial for preventing isch...

Although percutaneous tracheostomy is a standardized procedure, rare major complications are still being evaluated and discussed. We describe a case of patient, with hemodynamic and respiratory stability, who displayed massive hemorrhage after 16 days of "Ciaglia Blue Rhino" tracheostomy. Unfortunately, neither prompt resuscitation maneuvers nor the surgical approach saved the life of patient.
