From Pre-Existing Renal Failure to Perioperative Renal Protection: The Anesthesiologist's Dilemmas.

CONTEXT: Pre-existing renal dysfunction presents specific features that anesthesiologists must deal with. Anesthesia and renal function are connected and can interfere with each other. Induced hypotension anesthesia and the toxic effects of anesthetic drugs can further deteriorate renal function. EVIDENCE ACQUISITION: Decreased renal function can prolong anesthetic drug effects by decreased elimination of these drugs. Anesthesia can deteriorate renal function and decreased renal function can interfere with drug elimination leading to their prolonged effect. The anesthesiologist must understand all the physiological aspects of the patient, renal protection, and the relationships between anesthetic drugs and renal function. This review article aims to summarize these aspects. RESULTS: Perioperative renal failure and renal protection is a crucial moment in clinical practice of every anesthesiologist. CONCLUSIONS: Good knowledges for renal function remain a hallmark of daily practice of the anesthesiologist, considering renal function as an important determinant factor in anesthesia practice.

Anesthetic considerations on adrenal gland surgery.

Adrenal gland surgery needs a multidisciplinary team including endocrinologist, radiologist, anesthesiologist, and surgeon. The indications for adrenal gland surgery include hormonal secreting and non-hormonal secreting tumors. Adrenal hormonal secreting tumors present to the anesthesiologist unique challenges requiring good preoperative evaluation, perioperative hemodynamic control, corrections of all electrolytes and metabolic abnormalities, a detailed and careful anesthetic strategy, overall knowledge about the specific diseases, control and maintaining of postoperative adrenal function, and finally a good collaboration with other involved colleagues. This review will focus on the endocrine issues, as well as on the above-mentioned aspects of anesthetic management during hormone secreting adrenal gland tumor resection.

Anesthetic challenges of patients with cardiac comorbidities undergoing major urologic surgery.

The cardiac patient undergoing major urologic surgery is a complex case requiring a great attention by the anesthesiologist. Number of this group of patients having to go through this procedure is constantly increasing, due to prolonged life, increased agressiveness of surgery and increased anesthesia's safety. The anesthesiologist usually has to deal with several problems of the patient, such as hypertension, chronic heart failure, coronary artery disease, rhythm disturbances, intraoperative hemodymanic changes, intraoperative bleeding, perioperative fluid imbalance, and metabolic disturbances. A cardiac patient undergoing major urologic surgery is a complex case requiring a great attention by the anesthesiologist. The scope of this review article is to present the most frequent issues encountered with this group of patients, and to synthetically discuss the respective strategies and maneuvers during perioperative period, which is the major challenge for the anesthesiologist.

Acute right intrathoracic gastric volvulus. A rare surgical emergency.

The acute intrathoracic gastric volvulus is a rare condition, difficult to diagnose and treat. It consist in a abnormal organo-axial rotation over 180°, associated with gastric obstruction or strangulation. More uncommon condition is the gastric volvulus caused by a right sliding diaphragmatic hernia and dislocating the stomach, or part of it, on the right hemithorax. Gastric volvulus classic clinical presentation described by Borchardt, consist on a triad of severe epigastric pain, vomiting followed by retching without ability to vomit and difficulty or inability to pass a nasogastric tube. Imaging, beginning from a simple chest radiograph showing an elevated gastric air-fluid level in lower lung segments, can help to define diagnosis and to determine the immediate necessity to operate trying to avoid fatal complications as gastric ischemia, perforation or haemorrhage. We present the case of a 58 year-old man arrived at our Emergency Department with moderate acute epigastric pain and already vomiting from 4 hours. The patient underwent initially a chest radiograph, Computed Tomography, upper digestive endoscopy, upper digestive contrasted radiology and then was operated. Post operative situation of the patient on recovery and during the 3 months follow up didn't experience any pain or difficulty in feeding.
