Background: Hypotension is commonly occurred with Spinal anesthesia. Colloids and Crystalloids are used preoperatively to prevent hypotension. Objective: To examine the effect of fluid (crystalloid vs. colloid) preloading on hemodynamic stability in old patients planned for lower limb orthopedic operations spinal Patients methods: Eighty undergoing surgery under anesthesia were included this wo...

Radical mastectomy is routinely performed under general anaesthesia, but geriatric patients with compromised cardio-pulmonary function are at increased risk of morbidity and mortality. We report successful perioperative management of radical mastectomy with sole paravertebral block in a 92 years old female with compromised cardio-pulmonary function and kyphoscoliotic spine. Single needle thorac...

A 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. For most of his two-month stay in the Intensive Care Unit (ICU), he was dependent on dopamine support to maintain hemodynamic stability. Keeping in mind evidence from the literature, that electrostimulation of acupoints Neiguan (PC - 6) and Jianshi...

Cardiac surgery is associated with intense nociceptive and autonomic stimulation especially during sternotomy and aortic root dissection and moderate-to-high dose opioids are required to blunt the hemodynamic and neuroendocrine response to this kind of procedures. However, episodes of unwanted sympathetic activation leading to intraoperative hypertension are not always preventable with a fentan...

The heart and the kidneys share responsibility for maintaining hemodynamic stability and end-organ perfusion. Connections between these organs ensure that subtle physiologic changes in one system are tempered by compensation in the other through a variety of pathways and mediators. In the setting of underlying heart disease or chronic kidney disease, the capacity of each organ to respond to per...

Opioids have been considered for their hemodynamic stability. Remifentanil is an opioid analgesic with rapid metabolism and fast primary effect and recovery. In this paper, a very rare effect of using remifentanil along with propofol was presented. An 84-year-old male patient with severe aortic stenosis underwent general anesthesia. In order to induce anesthesia and maintain it, fentanyl, pancu...

OBJECTIVE To report a case of severe hemorrhagic cystitis successfully treated by bilateral percutaneous nephrostomy. METHODS The case of a 67-year-old female patient who had monosymptomatic gross hematuria with clots is reported. RESULTS Standard conservative treatments failed and the patient developed a clot-retention plugged bladder. Endoscopic evacuation and electrocoagulation of bleedi...

The incidence of intraoperative arrhythmia is extremely high, and some arrhythmias require clinical attention. Therefore, it is essential for the anesthesiologist to evaluate risk factors for arrhythmia and understand their etiology, electrophysiology, diagnosis, and treatment. Anesthetic agents reportedly affect normal cardiac electrical activity. In the normal cardiac cycle, the sinoatrial no...

BACKGROUND Etomidate frequently leads to myoclonic jerks during anesthetic induction. This study aimed to detect if pretreatment with magnesium decreases myoclonus incidence. METHODS A hundred ASA (the American Society of Anesthesiologists) I-II patients were included and randomized into 2 groups. Three minutes before etomidate induction of anesthesia (by 0.3 mg/kg intravenous etomidate), Gro...

propofol is a widely used anesthetic drug because of its minor complication and also its fast effect. one of most popular complication in using this drug is pain during injection that is more sever in new generation of its components (lipid-free microemulsion). other complications of propofol are bradycardia and hypotension. this study compares 3 drugs with placebo in control of these complicat...
